From 5749157f15740fa515487f9eddbbea446c0e0b61 Mon Sep 17 00:00:00 2001 From: Rafael Richards Date: Sat, 30 May 2026 21:07:28 -0400 Subject: [PATCH 1/2] B2: IRIS-native backends for STDCRYPTO / STDCOMPRESS / STDHTTP MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add IRIS arms to the three optional modules behind a runtime engine-detect seam, so each module's public API and *TST.m suites work identically on YottaDB and IRIS. One .m per module — the IRIS arm is an else-branch in the existing dispatch helper, never a second source file (architecture invariant). Engine seam: - STDOS: new $$engine^STDOS() → "iris"/"ydb" via $ZVERSION["IRIS" (safe on both engines; never touches the YDB-only $ZYRELEASE). Backends (YDB $&pkg.fn path unchanged; IRIS branch added ahead of it): - STDCRYPTO → $SYSTEM.Encryption.SHAHash / .HMACSHA (native; raw-byte digests identical to libcrypto; HMACSHA(bits,data,key) arg order verified vs RFC 4231). - STDHTTP → %Net.HttpRequest (native; Send/StatusCode/Data/Headers). respHeaders rebuilt as a status-line+headers block so request^STDHTTP parses both engines identically. Live success path smoke-tested (GET → 200/body/headers). - STDCOMPRESS → embedded Python: zlib (wbits 31 gzip / -15 raw deflate) + libzstd.so.1 via ctypes (no zstd Python module ships, but the system .so does). M<->Python binary bridged latin-1 (codepoint==byte for 0..255). Core-harness portability (required for the optional suites to run on IRIS): - STDASSERT.raises: $ZLEVEL+ZGOTO unwind is YDB-only ( on IRIS). Branch on an inlined $ZVERSION probe — IRIS wraps the XECUTE in ObjectScript try/catch (helper irisCapture), which unwinds any $$ depth and preserves $ECODE. YDB path unchanged. (Discovery logged.) - STDCOMPRESSTST: ported $ZCHAR/$ZASCII -> $CHAR/$ASCII (YDB-only intrinsics; byte-identical under YDB byte mode and on IRIS, no assertion weakened). - IRIS embedded-Python hangs through M $ETRAP -> the IRIS dispatch helpers use ObjectScript try/catch instead. (Discovery logged.) Verification (via normal `m test`, no hand docker exec): - IRIS (vista-iris): 4 optional suites, 150 assertions, 0 failed (STDCRYPTOTST 23, STDCRYPTODOCTST 1, STDCOMPRESSTST 59, STDHTTPTST 67). - YDB core (m-test-engine, byte mode): 44 suites, 2414 assertions, 0 failed — no regression (STDASSERTTST 35/35, STDOSTST 30/30). YDB optional tier still awaits the engine-side callouts (follow-up B1). Regenerated dist/ (STDOS gained engine()); module-tracker rows + 3 discoveries entries updated in the same commit. fmt clean; lint 0 error-level.

Writing `set rc=$ZF("crypto_sha256",data,.out)` triggers the PostToolUse `m fmt` hook, which silently rewrites the line as `set rc=$zfind("crypto_sha256",data,.out)` — and `$zfind` is a string-search intrinsic with completely unrelated semantics.

Keeps the novel payload — IRIS-native backends for the three optional modules — and drops everything master already provides. Kept (rebased onto master): - STDCRYPTO → $SYSTEM.Encryption.SHAHash / .HMACSHA (IRIS) ahead of the YDB $&stdcrypto callout. - STDHTTP → %Net.HttpRequest (IRIS) ahead of the YDB $&stdhttp callout. - STDCOMPRESS→ embedded-Python zlib + ctypes/zstd (IRIS) ahead of the YDB $&stdcompress callout. - STDCOMPRESSTST: $ZCHAR/$ZASCII → $CHAR/$ASCII (IRIS has no $ZCHAR; byte-identical under ydb_chset=M — matches the rest of the byte suites). Dropped (superseded by master's IRIS sweep): - The PR's $$engine^STDOS() helper — master's STDOS is already IRIS-ported by inlining $zversion["IRIS" per function; the 3 backends now use that same inlined-probe idiom (6 dispatch call-sites) instead of a helper. - The PR's STDASSERT irisCapture arm — master already has irisRaises (s9). Verified dual-engine (m-test-engine + m-test-iris): STDCRYPTOTST 23/23 and STDHTTPTST 67/67 green on IRIS as well as YDB; STDCRYPTODOCTST 1/1; STDCOMPRESSTST 59/59 on YDB. STDCOMPRESS-IRIS needs working embedded Python (the iris-community image lacks it — discoveries 2026-06-14); its logic is the PR's vista-iris-validated code, unchanged but for the proven seam. dist/ regenerated; module-tracker + discoveries + memory updated; make manifest-check / check-manifest / arch check (layer m) all clean.

There is no standalone setup() / teardown() pair.\n\nPublic labels:\n with(tag,code) ; XECUTEs code inside an auto-managed\n transaction scope; rolls back on exit\n and re-raises any error code raised\n inside ``code``.\n $$active() ; → 1 if any nested transaction is open\n (any TSTART, not just STDFIX-owned).\n register(tag,setupCode,teardownCode) ; declarative fixture\n invoke(tag,code) ; fixture-aware variant of with(): runs\n registered setup hook, then code, then\n registered teardown hook — all inside\n one rolled-back scope.\n cleanup ; idempotent rollback of any leaked\n transaction scope; safe at $tlevel=0.\n\nState layout (under ^STDLIB($job,\"FIX\",...)):\n STACK,$tlevel = tag ; one entry per open scope, set inside\n the transaction so TROLLBACK erases it.\n REG,tag,\"SETUP\" ; registered setup code\n REG,tag,\"TEARDOWN\" ; registered teardown code\n\n``trollback target`` (target = the pre-tstart $tlevel) rolls back\nexactly the level this frame opened, so nested with()/invoke() pairs\nroll back inner-only — bare ``trollback`` (which targets level 0) would\nunbalance every outer transaction.\n\nEngine portability (YDB + IRIS): YDB ``trollback n`` rolls back TO level\nn; IRIS ``trollback n`` rolls back n LEVELS (opposite meaning), so the\nrollback is engine-split — IRIS uses ``trollback $tlevel-target``. Full\npartial-rollback fidelity holds on both (nested inner-only rollback works\non IRIS too). REQUIREMENT: IRIS needs the namespace's database to be\nJOURNALED for ``TSTART`` (an unjournaled db faults ````);\nSTDFIX is therefore usable only on a journaled IRIS namespace. (TSTART is\nalso forbidden lexically inside an IRIS ``try{}``/``xecute``, but STDFIX's\nown tstart is a direct command, so this never bites here.)\n\nErrors set $ECODE to one of:\n ,U-STDFIX-EMPTY-TAG,\n ,U-STDFIX-UNREGISTERED-TAG,", "errors": [ "U-STDFIX-EMPTY-TAG", "U-STDFIX-UNREGISTERED-TAG" @@ -4858,7 +4858,7 @@ "description": "Opens a YDB transaction, sets the scope tag in the stack,\nXECUTEs code, then ``trollback $tlevel-1`` to roll back\nexactly this scope.

Gate = **install→test-in-place→back-out→ +verify-clean on both engines**. Symmetric: MSL keeps its bare-engine portability +lane *and* adds this (so MSL grows `make kids` at M0); VSL is VistA-only so every +green is KIDS-installed by construction. Rationale: a source-loaded test skips the +real contract (namespace mapping, env-check `XPDENV` run-twice, Required-Build +resolution, DD/XPAR/OPTION/KEY component install). Both gates (the 4 drift gates + +the KIDS-install loop) are **M0 deliverables — must exist before any seam crosses +TDD-red**.

Modular + TDD-proven verbs (`assemble/disassemble/load/install/verify/backout`), gated on + THREE invariants: round-trip, **deterministic assemble** (volatile fields + normalized → byte-identical export, diffable in git), **reversible install** + (install→backout leaves engine byte-identical, asserted — *not* "backout returned + OK"). **Git is source of truth for the KIDS package** (§7.2): a declarative + `kids/.build.json` spec + routines in git; the transport global is a + regenerable, drift-gated `dist/kids/` artifact — never an opaque blob. m-kids + owns the verbs + spec schema; each repo owns its own spec. New risks C13–C16; + CQ9/CQ10. +- **First vertical = walking skeleton (M1, §12.1):** lightest real seam = config + over XPAR (`VSLCFG`), MSL side already shipped (`STDENV`+`STDJSON`, zero new pure + code), one PARAMETER DEFINITION component.

Cause: the **unguarded `zgoto`-`$etrap` idiom** — + `set $etrap="set $ecode="""" zgoto "_parseLvl_":parseFail^STDJSON"` (parse) + + the same in encode(). IRIS rejects the YDB `zgoto LEVEL:label` form. **Same + issue STDASSERT.raises had (s9) — STDFS/STDHARN already guard it with + `if $zversion["IRIS" … quit` arms that return BEFORE the zgoto line.** STDJSON + is the only base module that left it unguarded (`grep zgoto src/*.m` → only + STDJSON among the 15). **Fix: add the IRIS try/catch arm.** NOT byte-mode. +2. **STDXML — crash ` parseElement+20^STDXML myNs("")`.** Cause: **null + (empty-string) subscripts** — `myNs("")` / `nsMap("")` (line 292/403) key the + default (no-prefix) namespace under `""`. **IRIS rejects null subscripts by + default; YDB allows them.** Fix forks: (a) sentinel key in code, (b) enable IRIS + null-subscripts at the namespace/runner, (c) scope STDXML YDB-only. → user + decision (the analog of the s10 byte-mode fork that never materialised). +3. **STDCSV — won't even COMPILE on IRIS:** loading STDCSV.m → + ` ERROR #5475: Expected end of line : '@callback@(curRow,.fields)' … + parseFile+34^STDCSV`. **IRIS ObjectScript does not support ARGUMENT INDIRECTION** + (`do @cb@(args)`) at all (only name-indirection `do @cb`). The whole routine + fails to compile → suite 0/0. Fix: build the call with `xecute` (hides the + dispatch from both compilers; by-ref `.fields` survives — xecute shares the + frame). Confirms the s10 `@callback@` note but it's a *compile* failure, not a + runtime one, so it kills the whole routine. +4. **STDDATE — 1 assertion fail "year in plausible range"** (reproduces on + m-test-iris source AND foia). `now()` returns a malformed date **`3567-05-6.157218T…`**. + Cause: `now()` reads `$ZHOROLOG` expecting YDB's **4-comma `d,s,u,t`** format + (days,seconds,microsec,tzoff). **IRIS `$ZHOROLOG` is a single elapsed-seconds + value (`630534.157234`)** → the whole thing lands in the day field. Fix: IRIS + arm using **`$ZTIMESTAMP`** (UTC already, in `$H` format `ddddd,sssss.ffffff` — + no tz subtraction needed). Keep YDB `$ZHOROLOG` path byte-identical. +5. **STDUUID — NO fix needed.** Source 131/131 on m-test-iris AND on foia (VISTA + namespace); KIDS-installed in isolation also **131/131**. The baseline's 129/2 + was **collateral from the crashing suites earlier in the same sequential IRIS + process** (same pattern as s9's raises-abort frame corruption). It will clear + once STDJSON/STDXML/STDCSV stop crashing — verify in the final full run. NOT + line-length truncation (STDUUID max line 103; STDDATE 157 / STDREGEX 191 are + longer and fine). + +**s11 fix #1 LANDED — STDJSON error-unwind ported to IRIS** (commit pending): +`parse()`+`encode()` get `if $zversion["IRIS" quit $$irisParse/$$irisEncode` +arms; new `parseBody(ctx,text,root)` holds the shared recursive-descent steps, +run inside `xecute "try { do parseBody^STDJSON(.ctx,text,.root) set ok=1 } catch +ex { set ok=0 }"`. **Gotcha I hit:** first cut put `set ok=1` AFTER the +trailing-garbage `if` on the same line — M's `if` scope runs to end-of-line, so +for valid input (peek="") the `if` was false and `set ok=1` was *skipped* too → +every parse returned 0. Fix: `set ok=1` BEFORE the `if … do raise` (a raise there +throws → catch → ok=0). YDB byte-identical (**STDJSONTST 209/209 on YDB**); IRIS +parse(valid)→1 / parse(invalid)→0 / encode roundtrips. **But STDJSONTST is NOT yet +green on IRIS** — two MORE tail issues surface once the crash clears (the suite +crashed at the first, masking them): **(a) byte-exact UTF-8** — `tParseStringUnicodeBmpEscape`/ +`tParseStringSurrogatePair` use **`$zchar`** (which IRIS DOESN'T support — `$char` +works, `$zchar`→``) to build expected UTF-8 *byte* strings, and feed +*literal* multibyte source that Atelier loads as Unicode chars on IRIS, not bytes +— the documented byte-mode boundary (CLAUDE.md: "STDJSON's UTF-8 decode assumes +1 M char == 1 byte"); **(b) empty-string object key** — `tParseObjectEmptyKeyAllowed` +stores `root("")` = a **null subscript** (the SAME class as STDXML's `myNs("")`). +So STDJSON needs the byte-mode decision (a) + the sentinel-key treatment (b) before +STDJSONTST greens. **Lesson: each crashing suite has SEVERAL stacked IRIS issues; +the 10/15 baseline undercounts the per-suite work.** + +**s11 fix #4 LANDED — STDDATE now() dual-engine.** `now()` engine-splits the +clock read: IRIS arm reads `$ztimestamp` (UTC in `$H` format `ddddd,sssss.ffffff`, +xecute-hidden so YDB never parses the name) → utcD/utcS/u; YDB arm keeps `$zhorolog` +(4-piece) unchanged; the UTC→ISO formatting tail is shared via `if…do / else do` +(no mid-routine label — a `goto`+label tripped M-MOD-024 phantom-entry-point lint +errors).

That let +STDCSV compile on IRIS, but the suite still crashed ` parseFile+21` — a +**latent STDFS bug**: `readLn`'s IRIS arm `xecute "try { read line } catch ex { set +eof=1 }"` left `$ECODE` set after the EOF `` (IRIS try/catch populates +`$ECODE`; YDB's `$ZEOF` path never does), so `readLines`→`parseFile`'s post-read +`if $ecode'=""` check tripped. Fix: the catch now `set $ecode=""` (EOF is a normal +loop terminator). STDFSTST passed before only because STDHARN resets `$ECODE` +between tests — the pollution only bit a caller that checks `$ecode` right after. +**STDCSVTST 59/59 + STDFSTST 50/50 on foia remote AND YDB.** YDB byte-identical. + +**s11 fix #2 LANDED — STDXML null-subscript sentinel (user chose sentinel-key).** +The default (no-prefix) XML namespace was keyed under `myNs("")`/`nsMap("")` — a +null subscript IRIS rejects (` parseElement+20`).

Goals & Non-Goals + +### Goals +- **Bi-directional.** VistA acts as both an HTTP **server** (inbound, exposing services) and an HTTP **client** (outbound, calling external services). +- **VistA-native.** Implemented as portable M routines, installable and patchable via KIDS, owned by a VistA namespace. +- **Portable.** One codebase runs on IRIS and YottaDB. Engine differences live only in named adapters (§3). +- **Modern auth.** OAuth 2.0 Bearer as the default credential; pluggable provider interface. +- **Reuses existing security model.** Maps onto NEW PERSON (#200), `^XUSEC` keys, and context options (OPTION #19) rather than inventing a parallel one. + +### Non-Goals (v0.1) +- Not replacing the RPC Broker or CPRS transport (Law 3 stands; this is additive). +- Not replacing HWSC/XOBW wholesale — outbound client may *coexist with* or later supersede it; not in scope to migrate existing XOBW consumers. +- No WebSockets, HTTP/2, or server-push in v0.1 (HTTP/1.1 request/response only). +- No HTML/UI rendering layer — this is a services stack (JSON-first). + +--- + +## 2. Architectural Principles + +These are the load-bearing decisions. Everything downstream follows from them. + +**P1 — The Broker is the precedent, not a dependency.** +The RPC Broker (`XWB`, file #8994, default TCP port 9200) is already a pure-M TCP listener that *jobs off each connection to a separate M process* and runs unmodified on both IRIS and YottaDB. This stack reuses that proven concurrency pattern but speaks **HTTP/1.1** on the wire instead of the Broker's (redacted, proprietary) framing. We are not extending or modifying `XWB` — we mirror its shape in a new namespace. + +**P2 — The only portable layer is M.** IRIS web tooling (CSP, `%CSP.REST`, `%Net.HttpRequest`, `%DynamicObject`) is ObjectScript and IRIS-only. None of it is permitted. Transport, TLS, and JSON are therefore implemented in M, with engine-specific mechanics isolated behind adapters. + +**P3 — Authenticate modern, authorize native.** A request carries a modern credential (OAuth2 Bearer). After validation it is *bound to a NEW PERSON #200 IEN* and the standard ambient `DUZ` is set. Authorization then reuses VistA's existing boundary: **OAuth scope → context option** (Law 5 — calls outside the context option's RPC/route surface are rejected regardless of identity). + +**P4 — Symmetric transforms.** The same request/response contract (§5) and JSON codec (§10) serve both inbound and outbound. The outbound client is the inbound parser run in reverse. + +**P5 — Configuration is data, not code.** All tunables (ports, TLS config names, AS introspection URL, timeouts) live in XPAR parameters (§11) with standard precedence, never hard-coded. + +--- + +## 3.

Inbound — Listener & Concurrency + +**Model:** Broker-style listener + per-connection worker (P1). + +1. **Listener process** (started by TaskMan or a startup option) opens a *listening* TCP socket on the configured port, with TLS enabled by referencing a named server TLS config (§9). +2. On each accepted connection it **jobs off** a worker M process bound to that connection, then returns to accept the next. (This mirrors the Broker's "jobs-off each connection to a separate M process.") +3. The **worker** handles the full HTTP exchange for that connection: parse → auth → route → dispatch → serialize → write. With keep-alive, the worker loops over multiple request/response cycles until close or idle timeout. +4. Worker exit closes the socket and the process. + +**Per-engine open item — socket handoff.** How the accepted connection is transferred from listener to jobbed worker differs between IRIS and YottaDB (socket inheritance vs. re-attach vs. accept-in-child). This is the single most engine-sensitive piece and is isolated in `VWEBL`. Candidate patterns to evaluate in v0.2: +- *Accept-in-child:* listener only owns the listening socket; each worker performs the `accept`. (Cleanest handoff, needs a serialization/lock so only one worker accepts at a time, or an engine accept-queue.) +- *Inherit-on-job:* listener accepts, then jobs a child that inherits the connected device. + +**Limits & safety (config-driven, §11):** max concurrent workers, per-connection idle timeout, max request line / header / body sizes (DoS guards), max requests per keep-alive connection. + +--- + +## 5. HTTP Parse/Serialize Contract (the portability seam) + +This is the contract every layer above the socket depends on. Defined as M local-array shapes (data contracts, not code). + +### 5.1 Request structure — `REQ` +| Subscript | Contents | +|---|---| +| `REQ("method")` | Upper-case verb (`GET`,`POST`,…) | +| `REQ("path")` | Decoded path, no query string | +| `REQ("rawpath")` | Raw path as received | +| `REQ("query",name)` | Percent-decoded query param (last-wins or list — TBD §15) | +| `REQ("hdr",lowername)` | Header value, name lower-cased for case-insensitive lookup | +| `REQ("body")` | Raw body (single node if small) | +| `REQ("body",n)` | Body chunk `n` (large/streamed bodies) | +| `REQ("body","len")` | Decoded content length | +| `REQ("json",…)` | Parsed JSON tree (populated lazily by handler via §10) | +| `REQ("peer")` | Remote address | +| `REQ("tls","cn")` | Client-cert CN, if mTLS provider used | + +### 5.2 Response structure — `RSP` +| Subscript | Contents | +|---|---| +| `RSP("status")` | Integer status code | +| `RSP("hdr",Name)` | Response header (original casing preserved) | +| `RSP("body")` / `RSP("body",n)` | Body content | +| `RSP("json")` | If set, codec serializes it to `body` and sets `Content-Type` | + +### 5.3 Parser obligations (`STDHTTPMSG`, in m-stdlib) +- Read request line; reject malformed / oversized (414/400). +- Read headers until CRLFCRLF; enforce header count/size caps. +- Body framing: honor `Content-Length`; support `Transfer-Encoding: chunked` (de-chunk into `REQ("body",…)`). +- Connection management: detect `Connection: close` vs keep-alive; HTTP/1.1 default keep-alive. +- Never trust client `Content-Length` beyond configured max. + +### 5.4 Serializer obligations (`STDHTTPMSG`, in m-stdlib) +- Emit status line, headers, blank line, body, with correct CRLF. +- Always set `Content-Length` (no server-side chunking required in v0.1). +- Set `Date`, `Server`, `Connection` headers; `Content-Type` defaulted from `RSP("json")`. + +**Why this seam matters:** the parser/serializer are *fully portable* and identical on both engines — which is exactly why they live in m-stdlib (`STDHTTPMSG`), not this package. Only the bytes feeding them (from the socket layer — `STDNET` + the `VWEBIO` engine adapter) are engine-specific. + +--- + +## 6. Router & Dispatch + +**Route table** is data (a global / FileMan file — TBD §15), so routes are installable and patchable, not compiled in. + +| Field | Meaning | +|---|---| +| method | Verb or `*` | +| pattern | Path pattern with named segments, e.g. `/patients/:dfn/meds` | +| handler | `TAG^ROUTINE` entry point invoked with `REQ`/`RSP` | +| scope | Required OAuth scope(s) → mapped to a context option (§7) | +| auth | `required` \| `optional` \| `none` (health checks) | + +**Dispatch sequence (per request):** +1. Match `REQ("method")` + `REQ("path")` → route (extract path params into `REQ("param",name)`). +2. No match → 404. Method mismatch on existing path → 405. +3. If `auth=required`, invoke auth middleware (§7). Failure → 401/403. +4. Invoke handler `TAG^ROUTINE`. Handler reads `REQ`, populates `RSP`. +5. Uncaught error → 500 with a sanitized body; full detail to audit log (§12). +6. Serializer writes `RSP`. + +Handlers call FileMan DBS APIs (`GETS^DIQ`, `FILE^DIE`, `UPDATE^DIE`, `LIST^DIC`, `FIND^DIC`) or existing RPCs — i.e., this stack is a new *transport* in front of unchanged application logic. + +--- + +## 7. Identity & Authorization + +The most consequential section. Authentication is modern and pluggable; authorization is native. + +### 7.1 Pluggable provider interface +Auth is a provider abstraction (`VWEBA` dispatches to a configured provider).

Extract `Authorization: Bearer ` from `REQ("hdr","authorization")`. +2. Call the configured AS introspection endpoint **using the outbound client (§8)** — VistA validating an inbound token by acting as an HTTP client is the dogfooding payoff. +3. AS returns `active`, `sub`, `scope`, expiry, etc. Inactive/expired → 401. +4. Cache introspection results briefly (config TTL) keyed by token hash to avoid an AS round-trip per request. + +> No private signing keys or JWT crypto live in VistA in this default path — which is exactly what keeps it portable and KIDS-clean. + +### 7.3 The DUZ binding (mandatory) +A valid token authenticates a *subject*; it does not grant the ability to touch FileMan. Per Kernel invariants, `DUZ` (caller's IEN in NEW PERSON #200) is ambient and required for nearly all VistA operations. The stack must therefore, after authentication: + +1. Map `principal.subject` → a NEW PERSON #200 IEN via a configurable identity map (claim → #200 lookup; candidate keys: secid, NPI, network username, or a dedicated mapping file — TBD §15). +2. No mapping → 403 (authenticated but not provisioned in VistA). +3. Set `DUZ` and establish standard context (`DUZ(0)`, division, etc.) for the worker process. +4. Optionally check `^XUSEC("KEY",DUZ)` for handlers gated on security keys. + +### 7.4 Authorization — scope → context option (Law 5) +Rather than a bespoke permission layer, map each OAuth **scope** to a **context option (OPTION #19)** whose RPC/route surface defines what that scope may do. A request is authorized only if its principal's scopes cover the route's required scope, *and* the dispatched operation lies within the mapped context option's surface. This reuses VistA's existing, audited security boundary instead of duplicating it. + +### 7.5 Audit +Every authentication decision (success/failure, subject, mapped DUZ, route, scope) is logged (§12). Consider correlating with SIGN-ON LOG (#3.081) conventions for consistency with existing authentication auditing. + +--- + +## 8. Outbound HTTP Client + +Symmetric with inbound (P4): build a `REQ`, serialize with `STDHTTPMSG`, open a client TLS socket (`STDNET` + `VWEBIO`), write, read response with `STDHTTPMSG` into `RSP`. + +**Capabilities (v0.1):** methods GET/POST/PUT/PATCH/DELETE; request headers + body; JSON convenience via §10; TLS verification against a named client TLS config (§9); connect/read timeouts; basic retry policy (config-driven). Used internally by the introspection provider (§7.2) and available to any M caller needing to reach an external service. + +**Relationship to HWSC/XOBW:** XOBW provides outbound web-service calls today but is Java-middleware-backed and outside the portable-M goal (and outside the documented VDL corpus). This client is a pure-M alternative. v0.1 coexists; a migration assessment for existing XOBW consumers is out of scope and noted for a later module. + +**Engine-specific:** only the client socket *open* (device params + TLS reference) lives in the adapter; request building, serialization, and response parsing are portable. + +--- + +## 9. TLS Configuration (per engine) + +TLS stays out of M *logic* but is invoked from M via the device `OPEN` referencing an **externally defined named TLS configuration**. The shape is symmetric across engines; the config mechanism differs. + +| | IRIS | YottaDB/GT.M | +|---|---|---| +| Config definition | SSL/TLS Configuration created administratively (Management Portal / security config) — **not** ObjectScript | TLS config entry in the encryption plugin config file (`ydb_crypt_config`), OpenSSL-backed | +| Referenced from M | TCP device `OPEN` with `/SSL="ConfigName"` | Socket device with `tls` deviceparameter naming the config | +| Server (inbound) | Server-role SSL config on the listening socket | TLS-enabled server socket (same plugin used for replication TLS) | +| Client (outbound) | Client-role SSL config, verify peer | Client TLS config, CA bundle for verification | +| mTLS | Require client certificate in config | Configure client-cert requirement | + +**Design rule:** the M code references a TLS config *name* pulled from XPAR (§11). Operators provision the actual cert/key/CA out-of-band per engine. No certs or crypto material in M, none in the KIDS build. This is what makes native TLS viable without ObjectScript *and* without an external proxy. + +> Note: the listening-socket TLS handoff to jobbed workers interacts with §4's socket-handoff open item — confirm the chosen handoff pattern preserves the TLS session per engine. + +--- + +## 10. JSON Codec + +IRIS `%DynamicObject` and YottaDB have no shared JSON facility, so a **portable pure-M JSON codec** (`STDJSON`, from m-stdlib) is a required build component, not an afterthought. + +- **Decode:** JSON text → M local array tree (objects as named subscripts, arrays as numeric subscripts, with type markers for null/bool/number/string). +- **Encode:** the inverse, with correct escaping and UTF-8 handling. +- **Interface:** `REQ("json",…)` and `RSP("json")` are the codec's I/O surfaces (§5). +- **Reuse vs. build:** evaluate existing open-source pure-M JSON implementations before writing one; whichever is chosen must pass a shared conformance test on both engines. (Decision §15.) +- IRIS-native JSON is explicitly **not** used (breaks portability, violates P2). + +--- + +## 11. Configuration Model (XPAR) + +All tunables are XPAR parameters under the package, honoring precedence **USR > LOC > SRV > DIV > SYS > PKG**. + +| Parameter (illustrative) | Scope typical | Purpose | +|---|---|---| +| `VWEB LISTEN PORT` | SYS | Inbound TLS port | +| `VWEB TLS SERVER CONFIG` | SYS | Named server TLS config (§9) | +| `VWEB TLS CLIENT CONFIG` | SYS | Named client TLS config (outbound) | +| `VWEB MAX WORKERS` | SYS | Concurrency cap | +| `VWEB IDLE TIMEOUT` | SYS | Keep-alive idle seconds | +| `VWEB MAX BODY` | SYS | Max inbound body bytes | +| `VWEB AUTH PROVIDER` | SYS | Active provider (introspection/mtls/…) | +| `VWEB OAUTH INTROSPECT URL` | SYS | AS introspection endpoint | +| `VWEB OAUTH CACHE TTL` | SYS | Introspection cache seconds | +| `VWEB IDENTITY MAP KEY` | SYS | Which claim maps to #200 | + +--- + +## 12. Audit & Observability + +- **Access log:** one record per request — timestamp, peer, method, path, status, bytes, latency, mapped DUZ, route, scope. +- **Auth log:** auth decisions per §7.5. +- **Error log:** uncaught handler errors with full stack/context (never leaked in the HTTP body). +- **Health endpoint:** `GET /healthz` (auth `none`) for liveness; optional readiness check that verifies listener + AS reachability. +- Storage mechanism (FileMan file vs. flat global vs. MailMan alert thresholds) — decision §15. + +--- + +## 13. Naming & Namespace + +`ZHWS` was the original **placeholder** — now **retired** (D0/D7); `MWEB` +was a brief interim pick, also superseded. The `Z*` prefix signals a +*local/non-distributed* namespace, which is wrong for a package committed +to VA distribution (D0). The working namespace must: + +- be **distinct from `STD*`** — the portable, engine-agnostic primitives + live in m-stdlib under `STD*`; this package is the VistA-coupled + consumer that *imports* them, and sharing the prefix would blur the + load-bearing line drawn in D0; and +- **signal the VistA coupling** with a `V`-prefix — this package *is* the + VistA side (FileMan handlers, `DUZ`/#200 auth, KIDS), so making that + visible in every routine name reinforces the D0 line right in the code. + This matches the sibling VistA Standard Library layer `VSL` + ([`msl-vsl-architecture.md`](msl-vsl-architecture.md)): + **`V*` = VistA-coupled package, `STD*` = portable library.** + +**Working namespace:** `VWEB` ("VistA Web Stack"); package title +*"VistA Web Services (on m-stdlib)."* The **final** routine namespace is +still **DBA-assigned** before any VA pilot (the working name is what the +spec and source carry until then). Routine names, options, parameters, +RPCs, security keys, and FileMan files all carry that namespace prefix +per §5 package invariants. + +> The split: `STD*` (m-stdlib) = portable / YottaDB+IRIS / no VistA +> dependency / library-distributed. `VWEB*` (this package) = VistA-coupled +> / KIDS-distributed / depends on m-stdlib being present at build time. + +--- + +## 14. KIDS Packaging + +- **Build:** a KIDS distribution containing the `VWEB*` routines, route-table file (if FileMan-backed), XPAR parameter definitions, context option(s) for scope mapping (§7.4), and any security keys. It declares the **`VSL` and m-stdlib base builds as KIDS Required Builds** — `STD*`/`VSL*` are installed once and reused, never bundled into this build (anti-duplication rule). +- **Patch identity:** `NAMESPACE*VERSION*PATCH` (e.g. `VWEB*1.0*1`). +- **Environment check / pre-install:** verify engine type and minimum version, TLS plugin/config availability, port availability, required Kernel patch level. +- **Post-install:** create XPAR defaults, register the startup option (listener launch via TaskMan), seed the route table. +- **No external artifacts in the build** — TLS material and AS endpoints are operator-provisioned (§9, §11), keeping the distributable pure-M and ATO-friendly. +- **Both engines:** the build installs identically on IRIS and YottaDB FOIA VistA; only the operator-provisioned TLS config mechanism differs. + +--- + +## 15.

This makes the **m-stdlib ↔ VistA-package separation load-bearing**: truly portable, engine-agnostic (YottaDB *and* IRIS) code lives in **m-stdlib under the `STD*` namespace**; the VistA/KIDS-coupled stack (listener, router, auth, DUZ binding, FileMan handlers, KIDS/XPAR) is a **distinct VistA package** that depends on the `STD*` (and `VSL`) **base builds** via KIDS **Required Builds** — installed once and reused, **never vendored/copied in** (the anti-duplication rule; see [`msl-vsl-architecture.md` §3.1/§4](msl-vsl-architecture.md)). The package namespace must therefore **not** be `STD*` (that would blur the line) but be `V`-prefixed to signal VistA coupling (see D7 + §13). | +| D1 | Socket handoff pattern listener→worker (§4) | Accept-in-child, pending per-engine spike | +| D2 | Query/header multi-value handling (§5.1) | Last-wins + list node for repeats | +| D3 | Route table store: FileMan file vs. global (§6) | FileMan file (installable/auditable) | +| D4 | Identity map claim → #200 (§7.3) | Dedicated mapping file keyed on a stable claim (secid?) | +| D5 | JSON: adopt existing pure-M lib vs. build (§10) | Adopt + conformance-test if license/quality fit | +| D6 | Add local-JWT provider (needs M crypto) (§7.1) | Defer to v0.2+; introspection covers v0.1 | +| D7 | Namespace (§13): working name + path to official assignment, given D0 | **Resolved — `VWEB`** ("VistA Web Stack"). Retired the `ZHWS` placeholder (`Z*` = local/non-distributed, wrong for VA distribution) and the interim `MWEB`. Working namespace is (a) **distinct from `STD*`** to preserve the D0 line, and (b) **`V`-prefixed** to signal VistA coupling in every routine name — matching the sibling `VSL` library (`V*` = VistA package, `STD*` = portable).

Goals & Non-Goals + +### Goals +- **Pure-M S3 client.** `PUT`, `GET`, `HEAD`, `LIST`, `DELETE`, and multipart + upload against an Amazon S3 bucket, with **zero** non-M dependency beyond the + TLS socket the engine already provides. +- **In-M SigV4.** AWS Signature Version 4 (`AWS4-HMAC-SHA256`) computed entirely + from `STDCRYPTO`'s HMAC-SHA-256 / SHA-256 primitives — no AWS SDK, no shell-out + to `aws` CLI, no helper service. +- **Portable.** One `STD*` codebase runs identically on YottaDB and IRIS; the only + engine-specific code (socket open + TLS) lives behind `VSLIO`/`STDNET`. +- **The log-egress worked example.** Stream `STDLOG` records out of VistA to S3 as + NDJSON, proving the Standard Library architecture's outbound seam end-to-end — *no log + ever written into a MUMPS global*. +- **Provider-swappable.** The same `STDLOG` calls ship to a different object store + (GCS/Azure) by swapping the `VSL*` sink, not the application code. + +### Non-Goals (v0.1) +- Not a full AWS SDK. Only the S3 operations the log-egress and object-IO use + cases need; no STS, no IAM, no DynamoDB, no SNS/SQS. +- No SigV4**A** (multi-region `AWS4-ECDSA-P256-SHA256`) — single-region SigV4 only. +- No browser-style POST policy uploads or pre-signed-URL query auth in v0.1 + (Authorization-header auth only; pre-signed URLs noted for a later phase). +- No S3 Select, no event notifications, no bucket administration (create/delete + bucket, policies, lifecycle) — those are console/IaC concerns, not a log shipper's. +- No credential vending logic — credentials are operator-provisioned config + (§10); the connector consumes them, it does not mint them. + +--- + +## 2. Why VistA Needs This — the Logging Gap (VDL-grounded) + +This is the load-bearing justification, and it is the same one the Standard Library +architecture draws in +[§6.2](msl-vsl-architecture.md#62-example-application-2--vista-log-streaming-to-aws-s3): + +**VistA has no mainstream, always-on logging facility, and the reason is +structural.** The only place a pure-M routine can durably write is a **global**, +and a global lives in the *same database that holds patient data*. A verbose log +global (`^XTMP`, a package-specific log file, a debug global) grows without bound, +inflates **journaling** and **backups**, competes for the same disk and the same +`^%ZIS`/FileMan I/O path as the live clinical workload, and can threaten the +production system. So sites keep logging sparse, ad-hoc, or switched off. + +Yet modern operations need the opposite: comprehensive, durable, **externalized** +logs for SIEM/security monitoring, HIPAA audit trails, debugging, and +observability. The fix is to **stop writing logs into the M database** and stream +them to cheap, immutable, lifecycle-managed object storage. + +**What the VDL corpus does and does not give us here** (full status in the Standard Library +architecture [§12](msl-vsl-architecture.md#12-documentation-gaps--status-after-the-v02-corpus-fetch)): + +- The **outbound socket path is documented** — Kernel's Device Handler exposes + `CALL^%ZISTCP` (ICR #2118, *Supported*, IPv6-compliant: `IPADDRESS`/`SOCKET`/ + `TIMEOUT` → `IO`/`POP`) and `CLOSE^%ZISTCP`. This is the exact, DBIA-registered + primitive `VSLIO` binds to open the TLS socket to S3 (`XU/krn_8_0_dg_device_handler_ug`, §18). +- **TLS is documented** — patch `XU*8*787` introduces the Kernel TLS routines and + the `DEFAULT TLS SERVER CONFIG` Kernel System Parameter (→ a named IRIS + `Security.SSLConfigs` entry); a *client*-role TLS config naming the AWS CA bundle + is the symmetric outbound case (`XU/krn_8_0_tm`, §18). +- **Background scheduling is documented** — a persistent TaskMan task + (`$$PSET^%ZTLOAD`, ICR #10063) drives the periodic flush, self-healing on + restart, and `^%ZTLOAD` can queue **without an I/O device** (`ZTIO=""`) — exactly + the shape for a job that owns its own outbound socket (`XU/krn_8_0_dg_taskman_ug`, §18). +- **Config is documented** — XPAR Parameter Tools (`$$GET^XPAR`, #8989.5/.51) hold + bucket/region/credential-reference parameters (`XT/ktk7_3p26sp`, §18). +- **What's absent:** the VDL carries **no** AWS-integration, object-storage, or + cloud-egress guidance for VistA at all — a corpus-wide search returns zero docs. + This connector is **greenfield** relative to the VDL: there is no prior VistA + pattern to conform to, only the Kernel primitives above to build on. + +> **Conclusion:** every VistA primitive the S3 log shipper needs (outbound socket, +> TLS, background task, hierarchical config) is documented and DBIA-registered in +> the gold corpus. The *AWS* half — SigV4 signing, the S3 REST contract — has no +> VistA precedent and is what this spec contributes, as portable `STD*` code. + +--- + +## 3. Architectural Placement — the Sharp Line + +This connector obeys the Standard Library architecture's +[sharp-line principle](msl-vsl-architecture.md#12-the-principle) +verbatim: **engine-agnostic capability is `STD*`; VistA-specific binding is +`VSL*`; nothing VistA leaks up into `STD*`, nothing portable is reimplemented in +`VSL*`.** + +The S3 connector splits cleanly because **everything about talking to S3 is +portable** and **everything about being inside VistA is not**: + +| Concern | Portable? | Home | +|---|---|---| +| SigV4 canonical request, string-to-sign, signing-key derivation, signature | ✅ pure math over HMAC/SHA | `STDSIGV4` (`STD*`) | +| S3 REST request construction (method, host, path, `x-amz-*` headers) | ✅ string building | `STDS3` (`STD*`) | +| NDJSON batch serialization | ✅ | `STDJSON` (`STD*`) | +| Payload SHA-256, hex encoding | ✅ | `STDCRYPTO` / `STDHEX` (`STD*`) | +| HTTP/1.1 framing of the request/response | ✅ | `STDHTTP` / `STDHTTPMSG` (`STD*`) | +| Opening the **TLS socket** to `s3..amazonaws.com` | ❌ engine-specific | `VSLIO` → `CALL^%ZISTCP` | +| **Where credentials live** (XPAR vs `.env`) | ❌ VistA-native | `VSLCFG` → `$$GET^XPAR` | +| **What drives the flush** (TaskMan vs cron) | ❌ VistA-native | `VSLTASK` → `^%ZTLOAD` | +| **What feeds the logs** (`STDLOG` sink binding) | ❌ side-effecting seam | `VSLS3` | +| Packaging (KIDS build, env-check, namespace) | ❌ VistA-native | `VSLBLD` | + +**The payoff of the split:** `STDS3` + `STDSIGV4` are usable by *any* pure-M +program — a YottaDB batch job, an m-cli command, a non-VistA service — with no +VistA present.

AWS S3 over REST — the SDK Surface We Reimplement + +The official AWS SDKs (boto3, AWS SDK for Java, etc.) are convenience wrappers +over the **Amazon S3 REST API**. Because the REST API is a stable, documented +HTTP contract, a pure-M client reimplements the *thin slice* the SDK would +otherwise generate. The operations this connector needs: + +| S3 operation | HTTP | Request-target (virtual-hosted-style) | Body | Success | +|---|---|---|---|---| +| **PutObject** | `PUT` | `https://.s3..amazonaws.com/` | object bytes | `200 OK` + `ETag` | +| **GetObject** | `GET` | `…/` | — | `200 OK` + object bytes | +| **HeadObject** | `HEAD` | `…/` | — | `200 OK` + metadata headers | +| **ListObjectsV2** | `GET` | `…/?list-type=2&prefix=

The bucket name is part of the **`Host` header**, not the +canonical URI, in virtual-hosted-style — this matters for the signature. + +**The three mandatory signed pieces** every request carries (from the AWS S3 +Authorization-header doc, §16): + +1. `Host` — the endpoint host (signs the bucket in virtual-hosted-style). +2. `x-amz-date` — request timestamp, **`YYYYMMDDgHHMMSSZ`** basic-ISO form (note: + `STDDATE`'s `$$now` returns *extended* ISO with separators; `STDSIGV4` strips + them — see §6). +3. `x-amz-content-sha256` — either the **hex SHA-256 of the payload** (signed + payload, recommended) or the literal `UNSIGNED-PAYLOAD`. + +The `Authorization` header then carries +`AWS4-HMAC-SHA256 Credential=…, SignedHeaders=…, Signature=…`. + +--- + +## 6. AWS Signature Version 4 — the Signing Process in Pure M + +SigV4 is four steps. Each maps directly onto an existing `STDCRYPTO`/`STDHEX` +primitive — which is *why* a pure-M signer is feasible with no new crypto code. + +**Step 1 — Canonical Request.** A newline-joined string: + +``` +\n +\n ; URI-encoded path, "/" not encoded +\n ; sorted, URI-encoded key=value&… +\n ; lowercased "name:trimmed-value\n", sorted by name +\n ; lowercased ";"-joined header names + ; hex SHA-256 of body, or UNSIGNED-PAYLOAD +``` + +Then hash it: `CR_HASH = SHA256_hex(CanonicalRequest)`. +→ M: `$$sha256^STDCRYPTO(cr)` (already returns 64-char lowercase hex). + +**Step 2 — String to Sign.** + +``` +AWS4-HMAC-SHA256\n +\n +///aws4_request\n ; the Credential Scope + +``` + +**Step 3 — Signing Key** (an HMAC chain; each step keys the next): + +``` +kDate = HMAC_SHA256("AWS4"+secretKey, yyyymmdd) +kRegion = HMAC_SHA256(kDate, region) +kService = HMAC_SHA256(kRegion, service) ; "s3" +kSigning = HMAC_SHA256(kService, "aws4_request") +``` + +→ M: each line is `$$hmacSha256Bytes^STDCRYPTO(key,data)` (raw-byte output so the +next HMAC keys on raw bytes, **not** hex — this is the single most common SigV4 +bug, and byte mode `ydb_chset=M` makes it exact). + +**Step 4 — Signature** (hex, this time): + +``` +signature = HEX( HMAC_SHA256(kSigning, StringToSign) ) +``` + +→ M: `$$hmacSha256^STDCRYPTO(kSigning,sts)` (the hex variant). + +**Authorization header:** + +``` +AWS4-HMAC-SHA256 Credential=/, SignedHeaders=, Signature= +``` + +> **Byte-mode correctness.** The signing-key chain passes **raw 32-byte HMAC +> outputs** as keys.

Reference Python (boto3) Code → MUMPS Equivalent + +The official AWS SDK for Python (**boto3**) is the reference implementation. Two +layers matter: the **high-level client** (what an application calls) and the +**low-level SigV4 signer** (what boto3/botocore does internally, and what AWS +documents as a standalone Python example — §17). `STDS3` mirrors the first; +`STDSIGV4` mirrors the second. + +### 7.1 High-level `put_object` + +**Python (boto3) — AWS S3 `put_object` reference:** + +```python +import boto3 + +s3 = boto3.client("s3", region_name="us-east-1") +resp = s3.put_object( + Bucket="my-vista-logs", + Key="vista/2026/06/07/site508-batch-0001.ndjson", + Body=ndjson_bytes, + ContentType="application/x-ndjson", + ServerSideEncryption="AES256", +) +etag = resp["ETag"] +``` + +**MUMPS equivalent (`STDS3`) — same call shape, explicit creds:** + +```M + ; build a credential context once (access key / secret / region / service) + new ctx + set ctx("accessKey")=ak,ctx("secretKey")=sk,ctx("region")="us-east-1",ctx("service")="s3" + ; + new opt,resp + set opt("contentType")="application/x-ndjson" + set opt("sse")="AES256" ; → x-amz-server-side-encryption + set status=$$putObject^STDS3(.ctx,"my-vista-logs","vista/2026/06/07/site508-batch-0001.ndjson",ndjson,.opt,.resp) + if status'=200 set $ec=",U-STDS3-PUT-"_status_"," + set etag=resp("header","etag") +``` + +`boto3` reads credentials/region from the environment or `~/.aws/config`; the +portable `STDS3` takes them as an explicit `ctx` array (no ambient state — that is +`VSLCFG`'s job under VistA, §10). + +### 7.2 The SigV4 signing routine + +This is the heart of the connector.

Configuration & Credentials Model + +Portable `STDS3`/`STDSIGV4` are **stateless about config** — they take an explicit +`ctx`. Under VistA, `VSLCFG` builds that `ctx` from **XPAR parameters** +(`$$GET^XPAR`, #8989.5/.51, with the standard `USR > LOC > SRV > DIV > SYS > PKG` +precedence — `XT/ktk7_3p26sp`, §18): + +| XPAR parameter (illustrative) | Scope | Purpose | +|---|---|---| +| `VSLS3 BUCKET` | SYS | Target log bucket | +| `VSLS3 REGION` | SYS | AWS region (e.g. `us-gov-west-1` for GovCloud) | +| `VSLS3 ENDPOINT` | SYS | Host override (path-style / S3-compatible / FIPS endpoint) | +| `VSLS3 TLS CLIENT CONFIG` | SYS | Named client TLS config (CA bundle) for `VSLIO` | +| `VSLS3 KEY PREFIX` | SYS/DIV | Object-key prefix (e.g. `vista//`) | +| `VSLS3 SSE` | SYS | Server-side encryption mode (`AES256` / `aws:kms`) | +| `VSLS3 FLUSH SECONDS` | SYS | Background flush interval (`VSLTASK`) | +| `VSLS3 BATCH MAX BYTES` | SYS | Single-PUT vs multipart threshold | + +**Credentials — never in XPAR plaintext.** Options, in precedence order +(D-S3-1): + +1. **IAM role / instance profile** (preferred where the VistA host runs on EC2 or + has an SSM/IMDS path) — the credential is fetched at flush time, short-lived, + never persisted. `ctx("sessionToken")` carries the STS token. +2. **A named credential reference** that `VSLCFG` resolves out of an + operator-managed secret store (file with restricted perms, or the engine's + secured config), **never** the access key in a global or an XPAR value. +3. The access key/secret in an OS-protected config file readable only by the + VistA service account — the floor, not the recommendation. + +This mirrors the Standard Library architecture's TLS rule: **no credential material in M +source, in a global, or in the KIDS build** — only a *reference* to operator- +provisioned material, resolved at runtime. + +--- + +## 11. Interfacing with the v-stdlib — `VSLS3` Log Sink + +This section is the connector's primary recommendation set: **how `STDS3` plugs +into VSL to ship VistA logs.** It realizes the data flow drawn in the +Standard Library architecture +[§6.2 Mermaid diagram](msl-vsl-architecture.md#62-example-application-2--vista-log-streaming-to-aws-s3). + +### 11.1 The binding — `STDLOG`'s sink seam → `VSLS3` + +`STDLOG` is a **side-effecting seam** (Standard Library architecture §2.3 / §4.2): the +logging *API* is portable, the *sink* is pluggable. Recommendation: + +- VistA application code calls the ordinary, unchanged `STDLOG` API + (`do info^STDLOG(...)`, `do error^STDLOG(...)`). It has **no knowledge of S3**. +- `VSLS3` registers as `STDLOG`'s sink at install time. Each log record is + appended to an in-process (or short-lived spool) **batch buffer**, not written + through to S3 synchronously — logging must never block the clinical path on a + network round-trip. +- A record is a flat M array; `VSLS3` serializes the batch to **NDJSON** with + `STDJSON` (one JSON object per line: timestamp, level, message, `DUZ`, routine, + job number, station). + +### 11.2 The flush — `VSLTASK` drives egress + +- A **persistent TaskMan task** (`$$PSET^%ZTLOAD`, ICR #10063 — Standard Library + architecture §3.5) wakes every `VSLS3 FLUSH SECONDS`, or when the batch crosses + `VSLS3 BATCH MAX BYTES`, whichever first. +- It composes the object key (`///

/-.ndjson`), + calls `$$putObject^STDS3` (or the multipart trio for large batches, §7.4), and + on `200 OK` clears the flushed batch. +- The task queues **without an I/O device** (`ZTIO=""`) and owns its own outbound + socket — exactly the TaskMan shape the corpus documents for this (§2). + +### 11.3 The socket — `VSLIO` is the only engine-specific hop + +- `STDS3` hands the assembled, signed request to the HTTP layer; under VistA the + socket open is `VSLIO` → **`CALL^%ZISTCP`** (ICR #2118: `IPADDRESS`/`SOCKET`/ + `TIMEOUT` → `IO`/`POP`) against the **`VSLS3 TLS CLIENT CONFIG`** named config + (Standard Library architecture §3.6). No certificate material in M; the config names the + AWS CA bundle out-of-band. + +### 11.4 Durability & back-pressure recommendations + +The risk a log shipper must not create is **threatening the clinical system it +observes** — the very failure mode that keeps VistA from logging today (§2). So: + +1. **Bounded spool, drop-oldest.** The batch buffer has a hard byte cap. If S3 is + unreachable and the spool fills, **drop oldest records and increment a dropped + counter** — never grow unbounded into the database. (Optionally spool to a + capped HFS file via `STDFS`, *not* a global, for crash durability — D-S3-4.) +2. **Asynchronous only.** No `STDLOG` call ever waits on the network. Flush is + always the background task's job. +3. **Idempotent keys + retry with backoff.** Each batch's object key includes a + monotonic sequence; a retried `PUT` overwrites identically (S3 `PUT` is + idempotent for a given key+body), so a flush that times out and retries cannot + duplicate or corrupt. `STDS3` returns the status; `VSLTASK` owns the + retry/backoff policy. +4. **Self-healing task.** `$$PSET^%ZTLOAD` persistence restarts the flusher if it + dies, so a transient crash doesn't silently stop egress. +5. **Fail-open for logging.** If S3 egress is broken, the clinical system keeps + running and logs keep batching/dropping with a counter — logging degrades, the + EHR does not. + +### 11.5 What the bucket side buys (the "why bother" payoff) + +Once logs are NDJSON objects in S3, the VistA operator gets — with **zero** extra +M code — what the M database never could: **lifecycle policies** (auto-expire/ +archive to Glacier), **immutability** (Object Lock for tamper-evident HIPAA audit +trails), **Athena/`SELECT`** ad-hoc query over the NDJSON, and **SIEM ingestion** +(the bucket is a standard SIEM source). The Standard Library architecture's §6.2 framing +holds: the M system's *only* outward act is one signed `PUT` across the trust +boundary; everything analytical happens off the live database. + +### 11.6 Provider-swap recommendation + +Keep `VSLS3` a *thin* sink: batching, spooling, key composition, and the +`STDS3` call. Put **nothing** S3-specific in `STDLOG` or in the application. Then +a future `VSLGCS` (Google Cloud Storage) or `VSLAZ` (Azure Blob) sink — each with +its own portable `STDGCS`/`STDAZBLOB` client and its own signer — drops in behind +the identical `STDLOG` seam, and the same VistA log calls ship to a different +cloud unchanged. This is the Standard Library architecture's reuse thesis, demonstrated. + +--- + +## 12. Security Considerations + +- **Credentials.** §10: prefer IAM-role/STS short-lived creds; never an access + key in a global, XPAR plaintext, M source, or the KIDS build. The signing key + derives the secret in-memory per flush and is never persisted. +- **Least privilege.** The IAM principal the shipper uses should hold *only* + `s3:PutObject` (+ `s3:AbortMultipartUpload`) on the one log-bucket prefix — + no `GetObject`/`DeleteObject`/`ListBucket` on the log path. `getObject`/`delete` + in `STDS3` exist for *other* object-IO consumers, not the log shipper. +- **TLS verification is mandatory.** `VSLIO`'s client TLS config must verify the + S3 endpoint against a pinned CA bundle — an unverified socket would let a + man-in-the-middle harvest signed requests. (The signature protects integrity, + not confidentiality of the log payload.) +- **PHI in logs.** Logs streamed off-box may contain PHI. Recommend: bucket-side + SSE (`AES256`/`aws:kms`), Object Lock for audit immutability, a Government/ + BAA-covered account (GovCloud region where required), and an application + discipline that log *messages* avoid raw PHI where feasible. This is a policy + surface the connector enables but cannot enforce — call it out in the `VSLS3` + DIBRG. +- **GovCloud / FIPS.** `VSLS3 REGION` + `VSLS3 ENDPOINT` support + `us-gov-west-1`/`us-gov-east-1` and FIPS endpoints + (`s3-fips..amazonaws.com`) — likely mandatory for a VA deployment. +- **Clock skew.** SigV4 rejects requests whose `x-amz-date` skews > 15 min from + S3's clock (`403 RequestTimeTooSkewed`). The VistA host's time must be NTP-synced; + `VSLTASK` should surface skew-class 403s as an alert, not a silent retry loop. + +--- + +## 13. Testing Strategy + +**Portable layer (`STDS3` / `STDSIGV4`) — m-stdlib gates, no VistA, no network:** + +- **SigV4 known-answer vectors.** Assert `STDSIGV4` byte-exact against the + **AWS-published SigV4 test suite** and the worked example in the AWS S3 + Authorization-header doc (§16) — canonical request, string-to-sign, signing + key, and final signature each checked. This is the single highest-value test: + it catches the raw-byte-vs-hex chain bug (§6) deterministically with no S3. +- **Request-assembly snapshots.** `STDS3` builds for `putObject`/`listObjectsV2`/ + multipart are asserted against frozen expected byte strings (`STDSNAP`). +- **Round-trip against a local S3-compatible server** (MinIO/LocalStack) via + `STDS3`'s `endpoint` override — exercises the real HTTP path with no AWS + account, in CI. (Optional `make test-optional`-style suite, since it needs a + container.) +- **85%-per-module coverage**, fmt/lint, manifest/skill/doctest drift gates — same + as every `STD*` module. + +**VistA layer (`VSLS3`) — v-stdlib gates, live `VistaEngine`:** + +- `VSLS3` `*TST.m` runs inside a real FOIA VistA (YDB **and** IRIS) per the Standard Library + architecture's **no-mocks** rule (§8): real XPAR params, real `^%ZIS`/`CALL^%ZISTCP` + socket, real `$$PSET^%ZTLOAD` task. The S3 endpoint is a CI MinIO/LocalStack so + the test never touches production AWS. +- **Back-pressure tests:** spool-full drop-oldest, S3-unreachable degradation, + retry/backoff, sequence-key idempotency — assert the clinical-safety properties + of §11.4 explicitly. +- KIDS install → flush → verify object in bucket → back-out → verify-clean. + +--- + +## 14.

Purpose, Scope & the Sharp-Line Principle + +### 1.1 The problem + +m-stdlib fills the gaps in M's standard library as a **pure-M, engine-agnostic** +library: its core is dependency-free and byte-mode-correct on both YottaDB and +IRIS, with three optional `$ZF`-callout modules. It has **no VistA dependency** +and is tested on a bare engine. That portability is the whole value proposition +— `STDHTTPMSG` must be reusable by a non-VistA service exactly as easily as by a +VistA one. + +But a real VistA application cannot live on portable primitives alone. The +moment a primitive has a **side effect with a VistA-native home** — persisting a +record (FileMan, not a flat file), reading config (XPAR, not a `.env`), +authenticating a caller (Kernel `DUZ`/`^XUSEC`, not a bare token), opening a +listening socket (the Device Handler `^%ZIS` with a Kernel TLS config), writing +an audit record (a FileMan file / MailMan alert, not stdout), or shipping +(a KIDS build to a DBA-assigned namespace, not a `git clone`) — the portable +abstraction needs a **VistA-flavored back end**. + +### 1.2 The principle + +> **Engine-agnostic capability lives in `STD*` (m-stdlib). VistA-specific +> binding of that capability lives in a separate, independently-tracked, +> KIDS-installable package (`VSL` *(working)*). Nothing VistA leaks up into +> `STD*`; nothing portable is reimplemented in `VSL`.** + +This is the same load-bearing line drawn for the web stack in +[`https-stack-spec.md` D0](https-stack-spec.md): the commitment to **VA KIDS +distribution + IRIS compatibility** is what makes the separation mandatory +rather than stylistic. This document generalizes that line from "the web stack" +to **all** of m-stdlib. + +### 1.3 What "seamless" means here + +The requirement is that *all* m-stdlib functionality works against the VistA +back end. It does **not** mean every `STD*` module gets a VistA twin. It means: + +- **Pure/computational modules** (`STDJSON`, `STDREGEX`, `STDB64`, `STDHEX`, + `STDURL`, `STDDATE`, `STDCSV`, `STDXML`, `STDFMT`, `STDSTR`, `STDMATH`, + `STDCOLL`, `STDXFRM`, `STDSEMVER`, `STDUUID`, `STDCSPRNG`, the proposed + `STDHTTPMSG`/`STDHTTPD`/`STDJWT`/`STDVALID`/`STDESCAPE`) run **unchanged** on a VistA + engine — they touch no VistA seam, so the adapter layer is empty for them. + "Seamless" = *they already work*; `VSL` proves it under the VistA test + transport. +- **Side-effecting / environment modules** (`STDFS`, `STDOS`, `STDENV`, + `STDLOG`, `STDNET`, `STDCACHE`, `STDFIX`/`STDSEED`, and the Kernel-crypto + surface of `STDCRYPTO`) get a **VistA-backed adapter** in `VSL` that satisfies + the same contract using FileMan / XPAR / Kernel / Device-Handler instead of + POSIX. "Seamless" = *the contract is identical; only the back end differs*. + +The deliverable is **two deterministic, gated, fully-tested artifacts**: portable +`m-stdlib` (as today) and `VSL`/v-stdlib (new), the latter managed to a VA +VistA spec and **end-to-end tested against a live VistA** with no mocks. + +--- + +## 2.

Part B — VistA Integration Points Review + +All entry points below are drawn from the VistA gold-docs corpus; citations are +keyed to [§13](#13-references-vista-gold-docs). + +### 3.1 Packaging & distribution — KIDS + +VistA packages are built, transported, and installed via **KIDS** (Kernel +Installation & Distribution System): + +- **BUILD (#9.6)** defines a package version (`NAMESPACE VERSION`) and its + components: routines, FileMan files + data dictionaries, OPTIONs, SECURITY + KEYs, PARAMETERs, templates, protocols, REMOTE PROCEDUREs, mail groups, HL7 + links. **INSTALL (#9.7)** records each install event; **PACKAGE (#9.4)** holds + version + patch-application history. +- A **Transport Global** carries the BUILD + components in KIDS-closed-reference + form, staged under `^XTMP`, distributed as a Host-File-Server file or PackMan + message. +- **Install phases:** load distribution → run **environment-check routine** + (abort-this / abort-all / proceed) → answer pre/post-install questions → run + pre-install → install components → run post-install → re-enable options. + Programmatic hooks: `XPD*` utilities (`MES^XPDUTL`/`BMES^XPDUTL` output, + `$$VERSION^XPDUTL` current package version, `$$PATCH^XPDUTL` verify a patch is + installed, `$$NEWCP`/`$$COMCP`/`$$VERCP^XPDUTL` checkpoints, `$$OPTDE^XPDUTL` + disable/enable an option), `EN^XPDIJ` to task the install via TaskMan, + `UPDATE^XPDID` to drive the install progress bar. + - *(v0.2, grounded in the dedicated KIDS Developer's Guide §13.)* The + **environment-check routine must be a single self-contained routine** (it is + the only routine loaded on the target at check time) and **KIDS runs it + twice** — once at *Load a Distribution* and again at *Install Package(s)*; + the key variable **`XPDENV`** tells the routine which phase it is in. This is + exactly the hook `VWEB`'s env-check ([§7.2](#72-managed-to-a-va-vista-spec)) + uses to fail fast on engine type/version, TLS-config presence, and Kernel + patch level. +- **Patch identity:** `NAMESPACE*VERSION*PATCH` (e.g. `VWEB*1.0*1`); the + routine **namespace is DBA-assigned** for VA distribution — `Z*` is local-only + and not distributable. +- **Required Builds (the dependency mechanism, grounded in the KIDS DG, v0.2):** + the **`REQUIRED BUILD` (#11) Multiple** on BUILD (#9.6) names other builds a + consumer depends on, each with an **install action** — `WARNING ONLY` (warn, + continue), `DON'T INSTALL, LEAVE GLOBAL`, or `DON'T INSTALL, REMOVE GLOBAL` + (block until the prerequisite is present). At the installing site KIDS + verifies the requirement against the **PACKAGE (#9.4)** file's **VERSION (#22)** + Multiple and **PATCH APPLICATION HISTORY (#9.49,1105)** Multiple. This is the + concrete, file-level mechanism behind the "shared base builds, not vendoring" + rule below and the version-skew mitigation in [§10 R6](#10-risks): a consumer + declares the minimum `STD*`/`VSL*` base build it needs as a `DON'T INSTALL` + Required Build, and KIDS refuses to install against too-old a base. + +> **`VSL` consequence — shared base packages, not vendoring.** A library only +> earns its keep if it is installed **once** and reused by every routine on the +> system; copying its routines into each consumer's build is exactly the +> copy/paste duplication VistA already suffers from. So each layer ships as its +> **own KIDS base package**, and consumers declare dependencies via KIDS +> **Required Builds** (the BUILD #9.6 mechanism patches already use to require +> prior builds) — the same way every VistA package already requires Kernel (`XU`) +> and FileMan (`DI`): +> +> - **m-stdlib base build** — the `STD*` routines, installed once (DBA-assigned +> namespace for the VistA form; see [§11 Q9](#11-open-questions)). +> - **`VSL` base build** — `VSL*` adapters + FileMan file definitions +> (audit/config) + XPAR parameter definitions; **Requires** the m-stdlib base. +> - **`VWEB` (and any other app)** — `VWEB*` + OPTIONs (listener startup, context +> options) + an environment-check routine (engine type/version, TLS, Kernel +> patch level); **Requires** the `VSL` base (and m-stdlib transitively). +> +> Result: `STD*` and `VSL*` exist **once** on a VistA system and are callable by +> *any* M routine or package — m-stdlib/`VSL` become infrastructure base packages, +> peers of `XU`/`DI` in the dependency graph. No duplicated routines, no +> per-consumer drift. + +### 3.2 Data — FileMan Database Server (DBS) silent API + +VistA's rule is **no direct global access — all file I/O goes through FileMan +DBS calls or a documented DBIA.** The callable surface `VSL` will wrap: + +- **Read:** `GETS^DIQ(file,iens,fields,flags,target[,msg])` (multi-field into an + FDA-shaped target array; flags `E`/`I`/`N`/`R`/`Z`), `$$GET1^DIQ(...)` (single + field), `LIST^DIC` / `FIND^DIC` / `$$FIND1^DIC` (lookup/finder, LAYGO). +- **Write:** `UPDATE^DIE([flags,]fda,ien[,msg])` (add/file from an FDA, `+n` + add-nodes resolved to real IENs), `FILE^DIE` (file into known records), + `WP^DIE` (word-processing fields). +- **Validate:** `VAL^DIE` / `CHK^DIE` (external→internal validation without + filing). +- **Errors:** structured in `^TMP("DIERR",$J,...)` with `TEXT`/`PARAM` subnodes; + the `DIERR` local holds `count^lines`. `VSL` maps `DIERR` → m-stdlib's + `$ECODE` convention (`,U-VSL-…,`) so callers wrap with one `$ETRAP`. +- **IENS** = comma-terminated internal-entry-number string; **FDA** = + `FDA(file,"iens",field)=value`. + +> **`VSL` consequence:** the `STDFS`-shaped storage seam, when bound to VistA, +> is **not** a filesystem — it is FileMan. `VSL` exposes a FileMan-native +> storage adapter (`$$get/$$set/$$exists/$$kill` over `(file,iens,field)`), +> *not* a fake POSIX path layer. Code that genuinely needs a host file uses the +> HFS path of `STDFS` unchanged; code that needs persistence uses the FileMan +> adapter. + +### 3.3 Config — XPAR Parameter Tools + +The **PARAMETER (#8989.5)** + **PARAMETER DEFINITION (#8989.51)** files, accessed +via `$$GET^XPAR(entity,param,instance,format)`, `EN^XPAR`, `CHG^XPAR`, +`ENVAL^XPAR`, with an **entity-precedence hierarchy** (typ. `USR > LOC > SRV > +DIV > SYS > PKG`). This is VistA's native, audited, hierarchical config store. + +> **`VSL` consequence:** the `STDENV`/`STDOS` config seam binds to XPAR. `VWEB`'s +> tunables (`VWEB LISTEN PORT`, `VWEB TLS SERVER CONFIG`, …) are XPAR parameters, +> not a `.env` file — already reflected in [`https-stack-spec.md` §11](https-stack-spec.md). + +### 3.4 Identity & authorization — Kernel + +- **Ambient identity:** `DUZ` = caller's IEN in **NEW PERSON (#200)**; `DUZ(0)` + = FileMan access code; required for nearly all FileMan operations. +- **Authorization:** **security keys** in `^XUSEC(KEY,DUZ)`; **context options** + (OPTION #19, "B"-type) gate the callable RPC/route surface — the Broker's + `XWB CREATE CONTEXT` / `CRCONTXT^XWBSEC` handshake validates the user holds the + context option before any RPC runs. +- **Credential hashing:** Kernel `^XUSHSH` / `$$ENCRYP^XUSHSH` (one-way hash for + Access/Verify codes). +- **Sign-on / audit:** `XUS SIGNON SETUP`, `XUS GET USER INFO`, BSE token APIs; + the **SIGN-ON LOG (#3.081)**. + +> **`VSL` consequence:** the auth/crypto seam binds `STDCRYPTO`'s +> compare/hash to Kernel where appropriate, and provides the **principal → +> `DUZ`/#200 binding** + **scope → context-option** authorization that +> [`https-stack-spec.md` §7](https-stack-spec.md) requires. Portable token +> crypto (HMAC, base64url, constant-time compare) stays in `STD*`; the VistA +> *authorization decision* lives in `VSL`. + +### 3.5 Process & scheduling — TaskMan + +`^%ZTLOAD` queues background jobs; startup OPTIONs launch persistent processes. +A long-running listener (the `VWEB`/`VSL` socket listener) is started at system +startup as a TaskMan-launched OPTION, mirroring `XWB LISTENER STARTER`. + +> **`VSL` grounding (v0.2, from the dedicated TaskMan Developer's Guide §13).** +> The listener is the textbook use of a **persistent TaskMan task**: +> **`$$PSET^%ZTLOAD(ztsk)`** (ICR #10063) marks a task persistent so TaskMan +> **automatically restarts it if the lock on `^%ZTSCH("TASK",tasknumber)` is +> removed** — a self-healing listener, provided the task uses only incremental +> locks and is restartable from `^%ZTSK(task,…)`. `^%ZTLOAD` can queue **without +> an I/O device** (`ZTIO=""`) — the right shape for a socket server that owns +> its own device. Option-schedule control (`RESCH^XUTMOPT` set up, +> `OPTSTAT^XUTMOPT` read, `EDIT^XUTMOPT` edit) and `EN^XUTMDEVQ` (run a task +> directly or queued) cover `VSLTASK`'s scheduling surface; `TOUCH^XUSCLEAN` +> notifies Kernel of tasks that legitimately run ≥ 7 days, which a permanent +> listener does. So `VSLTASK` is a thin binding over `$$PSET^%ZTLOAD` + +> `^%ZTLOAD`, not new machinery. + +### 3.6 I/O & TLS — Device Handler + +Kernel's **`^%ZIS`** device handler opens/uses/closes devices from the **DEVICE +(#3.5)** file (incl. TCP socket devices: address/port/open-params). + +> **Documented socket APIs (v0.2, from the dedicated Device Handler Developer's +> Guide §13).** The DG names the exact, DBIA-registered primitives `VSLIO` +> binds: +> - **Outbound client connect — `CALL^%ZISTCP`** (ICR #2118, **Supported**, +> **IPv6-compliant**): inputs `IPADDRESS` (IPv4 or IPv6), `SOCKET` (1–65535), +> `TIMEOUT`; outputs `IO` (the connection reference) and **`POP`** (0 = success, +> positive = failed) — "works the same as a call to `^%ZIS`." **`CLOSE^%ZISTCP`** +> tears it down. This is the documented outbound-socket path for +> [§9.2](#92-outbound-client-path--symmetric) (the introspection client, the S3 +> log shipper). +> - **Handle-based device management — `OPEN^%ZISUTL` / `USE^%ZISUTL` / +> `CLOSE^%ZISUTL`** (open/use/close a device *by handle*): the right shape for +> a server juggling many concurrent connections, since each worker addresses +> its own device handle rather than the shared `IO*` variables. +> - **`^%ZIS` / `^%ZISC`** remain the standard single-device open/close. + +**TLS is configured out-of-band** (engine-level) and referenced **by name** from +the device — *no certificate material in M or in the KIDS build*. This matches +[`https-stack-spec.md` §9](https-stack-spec.md), and **v0.2 closes the prior +"TLS undocumented" gap on the server side**: the Kernel TM (§13) documents that +patch **`XU*8*787`** "introduces the necessary Kernel routines to support TLS +communication" and, on post-install, **auto-configures a Kernel System Parameter +named `DEFAULT TLS SERVER CONFIG`** that "points to the IRIS `Security.SSLConfigs` +entry the Kernel uses for TLS connections." Administrators can **repoint that +parameter to a renewed certificate config with immediate effect and no restart** +(seamless cert rotation), and TLS requires **IRIS for Health ≥ 2024.1.2** (earlier +builds carry a handshake defect, InterSystems WRC# 984378). This is precisely the +"named, out-of-band TLS config" model the architecture assumed — now grounded in +the corpus rather than inferred. + +> **`VSL` consequence:** `STDNET`'s portable socket primitives are wrapped by an +> `VSL` device adapter (`VSLIO`/`VWEBIO`) that performs the engine-specific +> `^%ZIS`/`CALL^%ZISTCP` `OPEN` against a named TLS config (`DEFAULT TLS SERVER +> CONFIG` or a per-app override). `STDNET` stays portable; the TLS/device +> mechanics are the adapter's only engine-specific code, and **no certificate +> material ever enters `STD*`, `VSL*`, or a KIDS build**. + +### 3.7 The existing connectivity precedent — RPC Broker (XWB) + +The **RPC Broker** is already a pure-M TCP listener (default port **9200**) that +**jobs off a separate M process per connection** and runs unmodified on IRIS and +YottaDB; **REMOTE PROCEDURE (#8994)** is the callable registry; **Broker Security +Enhancement (BSE)** adds mutual-TLS/IAM. The **M-to-M Broker** (XWB*1.1*34) does +VistA→VistA.

It is the inbound, request/ +response shape — the world *pulling* clinical data out of VistA over an open +standard. The §9 smoke test exercises this path end-to-end. + +### 6.2 Example application #2 — VistA log streaming to AWS S3 + +The complementary shape: an **outbound, fire-and-forget data egress** that proves +the same `STD*`/`VSL*` seams in the *write* direction. Where the FHIR app is a +client of VistA, the log shipper is VistA acting as a client of an external +service (AWS S3). + +**The need — why VistA barely logs today.** VistA has no mainstream, always-on +logging facility, and the reason is structural: the only place a pure-M routine +can durably write is a **global**, and a global lives in the *same database that +holds patient data*. A verbose log global (`^XTMP`, a package log file, …) grows +without bound, inflates journaling and backups, competes for the same disk, and +can threaten the live clinical system — so sites keep logging sparse, ad-hoc, or +switched off entirely. Yet modern operations need the opposite: comprehensive, +durable, externalized logs for security monitoring (SIEM), HIPAA audit trails, +debugging, and observability. The fix is to **stop writing logs into the M +database at all** and stream them to cheap, immutable, lifecycle-managed object +storage instead. + +**The application.** A log shipper binds the portable `STDLOG` sink seam (Layer 2) +to an S3 streaming sink (a `VSL*` adapter, Layer 3). VistA code anywhere calls the +ordinary `STDLOG` API; the records are batched, serialized to newline-delimited +JSON with `STDJSON`, signed with AWS SigV4 (`STDCRYPTO` HMAC-SHA256 + `STDHEX`), +framed by `STDHTTPMSG`, and `PUT` to an S3 bucket over TLS via `VSLIO`. A +background `TaskMan` job (`VSLTASK`) drives the periodic flush; bucket/region/ +credential references are XPAR parameters (`VSLCFG`). **No log ever lands in a +MUMPS global** — the legacy `^XTMP`-style sink is exactly what this replaces. + +The diagram stacks the levels as **separate bands, each in its own color**, with +the external **AWS Cloud** as a distinct dashed band at the bottom — the +whitespace and the colour break show the physical separation.

What remains undocumented is only the VA **OAuth2/SMART-on-FHIR Authorization-Server / token-introspection** contract — and a corpus-wide search found **zero** OAuth/SMART/FHIR/IAM docs anywhere in the 3,692-doc VDL inventory (not merely unfetched — absent). | Low–Med | TLS path: build to the documented `DEFAULT TLS SERVER CONFIG` model. **OAuth path RESOLVED to a gate (Q5):** the introspection-AS is an **open interface**; M0a–M5 don't touch OAuth and the **M6 smoke test uses a stub/test AS**, so wiring the production VA AS (specs **outside the VDL**, see [§12](#12-documentation-gaps--proposed-vdl-fetches)) is a **pre-pilot gate, not a dev blocker**. | +| R6 | **Shared-base version skew** — a consumer needs an `STD*`/`VSL*` API newer than the base build installed on a site (the flip side of *not* vendoring). | Medium | KIDS **Required Build** version constraints + m-stdlib SemVer; a consumer declares the minimum base version it needs, and the environment-check routine fails fast if the installed base is too old. Solve version management with dependency metadata, **not** by copying routines in. | +| R7 | **Coverage on real backends is slower / flakier** than local. | Low–Med | Deterministic fixtures (§8.2), pinned seed data, per-test FileMan teardown; quarantine genuinely non-deterministic VistA behaviors explicitly. | +| R8 | **Scope creep — `VSL` accreting VistA app logic** (becoming a package, not an adapter). | Medium | Hard rule: `VSL*` contains only the VistA *binding*; anything reusable goes to `STD*`; anything app-specific goes to the consumer (`VWEB`). | +| R9 | **IRIS without VistA** (IRIS-for-Health sites whose VistA differs from FOIA) — adapter assumptions may not hold. | Medium | Pin to documented Kernel/FileMan DBIAs only; test against the IRIS-for-Health VistA build, not bare IRIS. | + +--- + +## 11. Resolved Decisions + +**All resolved 2026-06-11 — no open questions remain before implementation.** The +two **external-dependency** items (Q5 VA OAuth AS, Q9 VA DBA namespace) are +**pre-pilot integration gates that do NOT block dev**: M0a–M6 run on FOIA VistA with +working namespaces and a stub AS (see each row). + +| # | Question | Decision | +|---|---|---| +| Q1 | **Name of the integration layer — DECIDED 2026-06-07.** Chosen: repo **`v-stdlib`**, routine namespace **`VSL*`**, name **"VistA Standard Library."** | **`VSL` / `v-stdlib` / "VistA Standard Library."** **Framing (load-bearing):** MSL and VSL are the **two tiers of one standard-library effort** — `m-stdlib` (`STD*`) is the *portable* tier; `v-stdlib` (`VSL*`) is the *VistA-native* tier that binds the portable seams to FileMan/Kernel/XPAR/Device-Handler/TaskMan. The name makes the parallel explicit (MUMPS Standard Library : VistA Standard Library) and positions VSL as a foundational base package (peer of `XU`/`DI`), **not** a transitional "bridge." **Scope guard:** the elevated name does *not* license scope creep — VSL remains **adapters/bindings only** ([R8](#10-risks)); portable logic always goes to `STD*` first (the priority rule). **Namespace verification (2026-06-07, three registries):** `VSL` is collision-free — exact + prefix-clear against the **470-package FileMan namespace registry** (empirical, from a live VistA), the **196-package KIDS registry** (`vista-kids-packages.csv`), and the **vdocs gold-docs corpus** (~0 mentions). **Alternatives evaluated & ruled out:** `VBL`/"VistA Bridge Library" (safe incumbent, but "bridge" undersells a permanent foundational layer); `VNL`/"VistA Native Library" (sharp "portable vs native" contrast — the runner-up); `VIL`/"VistA Integration Library" (**rejected** — name collides with the active VA product **VIA "VistA Integration Adapter"**, namespaces `VIA`/`VIAA`/`VIAB` present, see §3.9); `VDL`/"VistA Driver Library" (**rejected** — `VDL` = the **VA/VistA Document Library** that `vdocs` ingests, and "driver" is the org's term for the `m-driver-sdk` engine drivers); `VAL` (**rejected** — collides with Kernel `VA`/`VALM`). **Still required before VA pilot:** DBA confirmation against the VA Approved Application Abbreviations registry (may include namespaces reserved but not in FOIA/VDL) — verify both the `VSL*` routine **and** `^VSL(` global namespaces. | +| Q2 | **One `VSL` package or several?** | **DECIDED: single `VSL` base build v1.** Split (`VSLDATA`/`VSLAUTH`/`VSLNET`) only if install-footprint pressure appears — one Required-Build edge is simpler and matches the single-writer/one-package model. | +| Q3 | **FileMan storage contract.** | **DECIDED: a first-class `(file,iens,field)` FileMan API.** `VSLFS` is FileMan-native; `STDFS`'s HFS path is reserved for genuine host files.

The introspection-AS is an **open interface** — M0a–M5 don't touch OAuth; the **M6 smoke test runs against a stub/test AS**.

Documentation Gaps — Status After the v0.2 Corpus Fetch + +v0.1 listed seven proposed VDL fetches. v0.2 worked each against the vdocs gold +corpus and its full **3,692-document VDL inventory**. Outcome: **four gaps +closed, one is content-fetched but pending a gold-promotion fix, and two are +confirmed structurally absent from the VDL** (so no fetch can close them — they +need a non-VDL source or stay open interfaces).

The HWSC **Systems Management Guide** (`XOBW/xobw1_0sg`) §*Using SSL/TLS and Certificate-Based Authentication* corroborates cert-based auth. v0.1's "the cited `XU*8*787` patch was not in the index" was simply wrong — it is in `krn_8_0_tm`. | +| **VistA IAM / OAuth 2.0 / SMART-on-FHIR** | ⛔ | A corpus-wide inventory search for `oauth` / `smart on fhir` / `token introspection` / `fhir` / `identity and access` / `ssoi` returned **0 documents across the entire 3,692-doc VDL** — these are *not unfetched, they are absent*. VA's IAM/SSOi/STS and SMART-on-FHIR specs are not published in the VDL. `VWEB`'s introspection-AS contract must therefore be sourced **outside the VDL** and stays an **open interface** ([§11 Q5](#11-open-questions), [R5](#10-risks)). | +| **PARAMETER Tools full API reference** | ⛔ (best-available already cited) | The VDL carries **no consolidated Parameter Tools developer reference** — `XT/ktk7_3p26sp` (the patch supplement already cited) is the only Parameter-Tools API source on the VDL, and it does document the `XPAR`/`XPAREDIT` entry points (`ADD^XPAR`, `TEDH^XPAREDIT`, …).

Purpose & Relationship to the Architecture Doc + +The architecture doc establishes the four-layer model — **L1** engine +(YottaDB | IRIS), **L2** portable `STD*` (MSL), **L3** VistA-coupled `VSL*` +(VSL), **L4** VistA internals — and the principle that *engine-agnostic capability +lives in `STD*`; VistA binding of that capability lives in `VSL*`*. It defines the +**five side-effect seams** (storage, config, identity/crypto, sockets, +observability) and their adapters. + +What it does **not** specify, and what this plan supplies, is the **coordination +machinery** that lets two separately-tracked repos evolve without breaking each +other: + +- the **exact contract** VSL implements and how it is versioned (§5, §6); +- how MSL changes **propagate** to VSL and how VSL requests new MSL primitives + without forking the contract (§10); +- how the two are **distributed and depended-upon** without duplication (§7); +- the **shared test transport** that proves both halves on a live VistA (§8); +- the **milestone sequence** that de-risks the engine-sensitive pieces first (§11); +- the **per-seam build plan** with first-tests and DBIA pins (§12). + +Read the architecture doc first; this plan assumes its vocabulary (`VSLFS`, +`VSLCFG`, `VSLSEC`, `VSLIO`, `VSLLOG`, `VSLTASK`, `VSLBLD`, `VistaEngine`). + +--- + +## 2. The Coordination Problem — Why MSL⟷VSL Is the Crux + +MSL and VSL are not one project split in two; they are **two repos with opposite +constraints** that must nonetheless present a single, seamless capability: + +| | MSL (`STD*`) | VSL (`VSL*`) | +|---|---|---| +| **Dependency** | zero VistA; testable on a bare engine | requires FileMan + Kernel (a VistA-bearing engine) | +| **Distribution** | library source **and** a KIDS base build | KIDS only, DBA namespace | +| **Test transport** | `LocalEngine`/`DockerEngine` (+ dual-engine IRIS via `STDHARN`) | **`VistaEngine`** (live FOIA VistA, YDB **and** IRIS), no mocks | +| **Governance** | open library SemVer | VA KIDS spec, DIBRG, back-out | +| **Priority** | upstream — the contract owner | downstream — the contract consumer | + +The danger is **drift**: MSL changes a side-effecting signature and VSL's adapter +silently no longer satisfies it; or VSL grows logic that should have been a +portable `STD*` primitive; or a site installs a VSL build against too-old an MSL +base. Every one of these is a *coordination* failure, not a code failure. The rest +of this plan is the set of mechanisms that make each one impossible (or loudly +caught). + +The org already has a proven template for exactly this shape — the +**`m-driver-sdk ⟷ m-iris ⟷ m-ydb`** effort, whose rule is *"the SDK is the only +coupling — serialize the SDK, parallelize the drivers"* +([`vista-cloud-dev/CLAUDE.md`](../../../CLAUDE.md) § Driver coordination). This +plan applies the **same discipline** with MSL's seam contract playing the role of +the SDK. + +--- + +## 3. Coordination Principles (the load-bearing rules) + +1. **The contract is the only coupling.** The sole thing VSL depends on from MSL + is the **public signatures of the side-effecting `STD*` seams** (§5). Everything + else — pure modules, internal helpers — is free to change. Narrowing the coupling + to a named, versioned surface is what lets the two tracks move independently. +2. **Serialize the contract, parallelize the adapters.** Changes to the contract + are **batched and tagged** by the MSL track (frozen-MSL windows, §6). Within a + frozen window the seven VSL adapters can be built **in parallel** because they + share nothing but the frozen contract. +3. **MSL has priority; VSL never reimplements.** Per the repo rule + ([`m-stdlib/CLAUDE.md`](../../CLAUDE.md) § Architectural rule), any utility both + need is added to `STD*` **first** and imported. A `VSL*` adapter contains *only* + the VistA binding (§10, R-scope-creep). +4. **Install once, reuse everywhere.** `STD*` and `VSL*` are **shared KIDS base + builds** depended on via **Required Builds (#11)**, never vendored into consumers + (§7). +5. **No mocks, ever, at L3.** VSL adapters are proven against a **live VistA** on + **both** engines (§8). Pure `STD*` modules are proven to *run unchanged* under + the same transport (a conformance pass, not new code). +6. **Same gates both sides.** VSL adopts MSL's `; doc:`→manifest→skill→doctest + toolchain, `^STDASSERT`, 85%-per-module coverage, fmt/lint, TDD-red-first (§9). +7. **One writer per repo per branch.** MSL and VSL are edited in separate sessions + on separate branches; cross-repo features go **leaf-first, sequentially** + (MSL contract change lands and tags *before* the VSL adapter that consumes it). +8. **Registry-driven everything (the meta-principle).** *Every interface that can + drift is a generated, drift-gated artifact — never a convention, a review note, + or a tracker line.* One discipline, `source-tag → generate → registry → + red-gate`, governs **all** of them: the seam contract (§5.2), the ICR registry + (§5.4), the citation provenance (§5.5), the version-controlled KIDS build spec + (§7.2), and the `v` CLI command contract + registry + ([`v-cli-platform.md`](v-cli-platform.md)). A new layer earns trust by adding its + tag→registry→gate triple, not by being carefully watched. This is what makes the + whole vertical *provably* non-drifting rather than diligently maintained. + +--- + +## 4.

CI enforces this two ways: a signature-match check (§5.2) and the +no-duplication lint (§9). + +### 5.2 The contract artifact (a versioned interface manifest) + +MSL already emits `dist/stdlib-manifest.json` from `; doc:` blocks. **Extend it +with a machine-readable "seam-contract" view** so the coupling is a *file*, not a +convention: + +- Each side-effecting entry point in S1–S5 (+ `VSLTASK`/`VSLBLD` deps) is tagged + in its `; doc:` block with `@seam ` → the manifest gains a + `"seams": { "STDFS": { "contract_version": "1", "entry_points": [ {label, args, + returns, raises} ] }, … }` block. +- The **contract version** is an integer that bumps **only** when a seam signature + changes incompatibly (independent of the library SemVer — see §6). +- VSL pins the contract version it built against; **VSL CI fetches the pinned + MSL manifest and asserts the seam signatures still match** (a cross-repo drift + gate, the analogue of m-stdlib's own `make check-manifest`). + +This makes "MSL changed a seam and VSL didn't notice" a **red CI gate**, not a +production surprise. + +### 5.3 DBIA conformance (VSL→L4) + +The downward edge (VSL→VistA) must be **DBIA-conformant — no direct global +access** (architecture doc §3.2). Two calls are already pinned to **Supported** +ICRs (#2118, #10063). The remaining S1/S2/S3/S5 calls are documented Supported +APIs in the gold corpus (FM 22.2 DG, XT\*7.3\*26, Kernel) but their **ICR numbers +are a build-time deliverable**: each VSL adapter records the Supported ICR for +every L4 entry point it calls in its module doc, and `VSLBLD` lists them in the +KIDS build's ICR section. **§5.4 turns this from a tracked task (T-DBIA) and +prose into a generated registry + a red gate** — so the "every L4 call has a +Supported ICR / no direct global access" rule cannot be violated, not merely +audited. + +### 5.4 The L4 ICR registry + DBIA-conformance gate (VSL→L4) + +§5.3 states the *rule*; left there, enforcement is a tracked task and prose in +module docs — a silent-drift door. A VSL adapter could ship a call to an L4 +routine whose ICR is `Private`, retired, or simply never recorded, and nothing +would fail. v0.2 closes it with the same tag→manifest→gate mechanism boundary ① +uses. + +**The tag (source of truth).** Every L4 call site in `VSL*` source carries a doc +tag naming the ICR it relies on and where that ICR is documented: + +``` +; doc: @icr 2118 @status Supported @custodian XU @source XU/krn_8_0_dg_device_handler_ug#CALL^%ZISTCP +``` + +**The registry (generated).** `make manifest` (VSL repo) collects these into +`dist/icr-registry.json`, keyed by adapter: + +```json +{ + "VSLIO": [ + { "call": "CALL^%ZISTCP", "icr": 2118, "status": "Supported", + "custodian": "XU", + "source": { "doc_key": "XU/krn_8_0_dg_device_handler_ug", + "anchor": "§CALL^%ZISTCP", "retrieved_on": "2026-06-07", + "body_sha": "sha256:…" } } + ] +} +``` + +`VSLBLD`'s KIDS-build ICR section is **generated from this registry**, never +hand-kept — one source feeds both the gate and the build manifest. + +**The gate (`make check-icr`, red on violation).** In VSL CI it: + +1. parses VSL source for external-reference call patterns — `^DIC`, `^DIE`, + `^DIQ`, `^XPAR`, `^XU*`, `^XUS*`, `^%ZIS*`, `^%ZTLOAD`, `^XLF*`, … (the same + walk the §9 no-duplication lint performs, inverted from "flag scope creep" to + "flag unregistered DBIA"); +2. asserts **every** such call site is declared in `icr-registry.json` with a + non-retired `Supported` or `Controlled Subscription` ICR — undeclared, or a + `Private`/retired ICR, is **red**; +3. asserts no set/kill/`$ORDER` against a VistA file global appears outside a + declared FileMan-DBS call — the "no direct global access" rule (architecture + §3.2), mechanized. + +This turns risk **C8** and the no-direct-global rule from audited conventions +into a gate. Two calls are pinned today (#2118, #10063); the rest fill in as each +adapter lands (M1–M4) — but the **gate exists from M0**, so no adapter can merge +with an unregistered or direct-global call. + +### 5.5 Citation provenance — the VDL drift gate (→VDL) + +The design is *grounded* in VDL gold-docs — the ICR numbers, `CALL^%ZISTCP`'s +IO/POP contract, the `DEFAULT TLS SERVER CONFIG` model, Required Build #11. The +architecture doc's §13 records these as a **prose bibliography**, "verified +present" by hand on one date. But `~/data/vdocs` is a **shared, mutating lake** +(the §12 gold-promotion defect is itself proof the doc surface shifts): if a +re-ingested VDL release changes a cited API, nothing flags that the foundation +moved, and a citation can silently fall out of gold (`is_latest=1→0`) — which +already happened to six Kernel guides. + +The ICR number is the **shared key between the L4 edge and the VDL edge**, so one +artifact carries both. The `@source` field of each `icr-registry.json` entry +(§5.4) pins provenance to a content hash — `body_sha` is the hash of the cited +**normalized body section** under +`~/data/vdocs/documents/silver/text/03-normalized///body.md`. + +**The gate (`make check-citations`).** A `vdocs`-backed check (against `index.db` ++ the normalized bodies) — for every cited `doc_key`: + +1. it still resolves in the corpus; +2. it is still `is_latest=1` (gold) — a demotion is **red** (this rule would have + caught the six-guide regression); +3. the `body_sha` of the cited section is unchanged — a changed hash ⟹ the + documentation moved ⟹ the grounding must be re-reviewed and the `body_sha` + re-blessed; **red** until then. + +**Honest limitation.** This detects *corpus* change (the proxy), not +VA-publication change directly. Re-ingesting a newer VDL release is what surfaces +a VA change; this gate is what then **catches** it instead of letting it pass +silently. Because the corpus is external and shared, the gate runs on a cadence +(CI when the corpus pin changes, or a scheduled check) rather than every VSL +commit — but a failure **blocks the next contract freeze**. Before running it, +honor the vdocs shared-lake rule (check for a live operator run first). + +This promotes §13 from a bibliography to a **gated provenance registry**: the VDL +interface cannot move under the design without a red gate. + +--- + +## 6. Versioning & Dependency Pinning + +Three version axes, kept deliberately separate: + +| Axis | Lives on | Bumps when | Consumed by | +|---|---|---|---| +| **MSL library SemVer** (`v0.5.0` today) | m-stdlib tags | any MSL release | non-VistA consumers; VSL dev-time | +| **Seam contract version** (§5.2) | `stdlib-manifest.json` | a seam signature changes incompatibly | VSL CI drift gate | +| **MSL KIDS base patch** (`STD*1.0*n` / assigned ns) | the MSL KIDS build | a VistA-distributable MSL change | VSL Required Build #11 | + +**Frozen-MSL windows (the serialize-the-contract rule in practice):** + +1. The MSL lane **batches** any seam-contract changes a VSL milestone needs, then + **tags** an MSL release and rebuilds the KIDS base. +2. VSL **pins** that release: at dev-time it loads the tagged `STD*`; at + install-time its KIDS build declares **Required Build `STD* >= `** with + action `DON'T INSTALL, REMOVE GLOBAL` (so KIDS refuses to install VSL against + too-old an MSL base — the R6 mitigation, grounded in the KIDS DG: Required Build + #11 checks PACKAGE #9.4 VERSION #22 + PATCH APPLICATION HISTORY #9.49,1105). +3. VSL **never** forces an MSL change mid-window — it records **`needs MSL: `** + in its tracker (§10) and the MSL lane folds it into the next tag. + +**No `replace`/vendor directives.** Just as the drivers carry no `replace` against +the SDK, VSL carries **no vendored copy** of `STD*`; it depends on the pinned base +build. (See §7 for why install-time pinning is what makes "install once" safe.) + +--- + +## 7. Distribution Coordination — Install-Once Base Builds + +The anti-duplication rule (architecture doc §4.1) is a *coordination* rule: a +library earns its keep only if it lives on a system **once** and every routine +calls it. + +- **MSL gains a `make kids` target (M0)** producing a KIDS base build of the + `STD*` routines — **routines only** (no FileMan files, no options): a pure + shared-library package. Namespace per **Q9** (request `STD`, or remap to a + DBA-assigned prefix). This is the one place portable `STD*` acquires VistA + namespace governance. +- **VSL base build** (`VSLBLD`): `VSL*` routines + the FileMan file definitions + it owns (audit/config scratch) + XPAR parameter definitions + SECURITY KEYs + + **Required Build on the MSL base** (§6). Ships to its own DBA namespace. +- **VWEB (and any consumer)** adds only its own OPTIONs (listener startup, context + options) + a mandatory **environment-check routine** (engine type/version, TLS + config presence via `DEFAULT TLS SERVER CONFIG`, Kernel patch level, IRIS ≥ + 2024.1.2) and **Requires** the VSL base (MSL transitively). + +Result: `STD*` and `VSL*` exist **once**, callable by any routine — infrastructure +base packages, peers of `XU`/`DI` in the dependency graph. The dependency edges +are KIDS Required Builds, resolved at install time; **version management replaces +copying**. + +### 7.1 The `v pkg` domain (KIDS lifecycle) + +> **The deepest unknown in this whole plan.** §8.4 *requires* install-via-KIDS + +> back-out as the definition of green; this section says **what builds that +> capability**. It is the **first domain of the `v` CLI** — the platform for VistA +> developer tools ([`v-cli-platform.md`](v-cli-platform.md)): a developer types +> `v pkg install`, never "KIDS." The **offline** half (a `.KID` ↔ git tree) already +> ships as **pure Go** in `v-pkg` (the repo formerly `m-kids`/`kids-vc`, a +> byte-identical port of XPDK2VC). The **live `install → verify → uninstall`** half +> is **unbuilt and is the single largest discovery area** — KIDS gives no clean, +> scriptable, fully-reversible install — so it is its own **modular, TDD-proven** +> workstream, de-risked *before* anything depends on it (**M0a**, §11). It is **Go +> orchestration of VistA's existing Kernel KIDS routines** (`^XPDI…`) over the +> m-cli transport — **no new MUMPS package**. + +**Verbs (each an independently-testable unit). Offline = shipped; live = M0a:** + +| `v pkg` verb | Does | State | +|---|---|---| +| `v pkg unpack` (`decompose`) | `.KID` → per-component git tree (routines `.m`, DDs `.zwr`, Kernel entries) | shipped | +| `v pkg build` (`assemble`) | declarative git build spec → transport global / `.KID` | shipped | +| `v pkg check` (`roundtrip`) | unpack → build → re-parse, verify reproduced (exit 3 on drift) | shipped | +| `v pkg canon` · `parse` · `lint` | canonicalize IENs · summarize · PIKS data-class gate | shipped | +| `v pkg install ` | load + run install: env-check (`XPDENV`), components, pre/post hooks | **M0a (new)** | +| `v pkg verify ` | assert every declared component installed (INSTALL #9.7, PACKAGE #9.4, routine/file/param) | **M0a (new)** | +| `v pkg uninstall ` | reverse the install from a recorded manifest — restore prior state | **M0a (new)** | +| `v pkg status ` | query install / version state | M0a (new) | + +(Developer-friendly verbs; the VA terms — "back-out/rollback," "load distribution" +— stay in the docs, never the command, per the platform plain-language rule.) + +**The three invariants the tooling is gated on (deterministic, binary):** + +1. **Round-trip:** `unpack(build(spec)) == spec` and `build(unpack(kid)) == kid` + (modulo normalized volatile fields). The build cannot silently change shape + across the version-control boundary. +2. **Deterministic build:** the *same* spec produces a **byte-identical** export + — install date/time, user, and checksums **normalized/stripped** — which is what + makes the package diffable in git and lets a drift gate reproduce it (§7.2). +3. **Reversible install:** `install` then `uninstall` returns the engine to a state + **byte-identical** to pre-install (routine + global diff empty). This is the + core install/uninstall proof and the strongest thing §8.4's gate asserts — + *not* "uninstall returned OK," but "the system is provably back to where it was." + +**How it plugs in.** The m-cli `VistaEngine` loop (§8) *drives* these verbs: a +green is `v pkg build → install → verify → run *TST.m in place → uninstall → verify +clean`, on both engines. The `v pkg` domain owns the verbs + the build-spec schema; +each library repo owns only its own build spec (§7.2). New verbs are requested of +the `v pkg` lane the same one-directional way VSL requests MSL primitives (§10). + +### 7.2 Version-controlling the KIDS package (git is the source of truth) + +The requirement: **every M routine of MSL / VSL / consumer AND the KIDS packaging +of each is in git as diffable source** — never an opaque transport-global blob. +The model is the same `dist/`-artifact discipline m-stdlib already uses for its +manifest: + +- **Source of truth in git:** the routine `.m` files (in `src/`) **+ a declarative + build spec** `kids/.build.json` — the BUILD #9.6 definition in + human-readable, diffable text: component list (routines, file #s, params, keys, + options), Required Builds + versions, the env-check routine name, and the ICR + list (generated from `icr-registry.json`, §5.4). A package change shows up as a + **source diff**, reviewable like any other. +- **The transport global is a build artifact**, produced by `v pkg build`, + committed under `dist/kids/.kids` in **normalized** form (volatile fields + stripped — invariant #2) so it is *also* diffable, and **gated by a drift + check**: `v pkg build` must reproduce the committed export byte-for-byte, + exactly as `make check-manifest` gates `dist/`. A hand-edited export = red. +- **Result:** the KIDS package is reproducible from git, every change is a + reviewable diff, and the assembled artifact can never drift from its spec. + +This makes the KIDS packaging a **fourth gated artifact** alongside the seam, ICR, +and citation registries — the same `source-tag → generate → drift-gate` discipline +the rest of the vertical runs on. + +--- + +## 8. Test-Transport Coordination — VistaEngine, Dual-Engine, No-Mocks + +The two tracks share **one** new test transport, **`VistaEngine`** (architecture +doc §8): a live FOIA VistA on **YDB** and a second on **IRIS-for-Health**, driven +by the m-cli runner alongside the existing `LocalEngine`/`DockerEngine`/`SSHEngine`. + +**The conformance matrix (owned by VSL, references MSL module versions):** + +| Half | What it proves | Where it runs | New code? | +|---|---|---|---| +| **A — pure MSL conformance** | every pure `STD*` module runs **unchanged** under VistaEngine (JSON, HTTP codec, JWT, base64url, URL, CSPRNG, …) | VistaEngine, both engines | no — a conformance pass | +| **B — VSL adapter tests** | each `VSL*` adapter's `*TST.m` passes against **real** FileMan/XPAR/`DUZ`/`^%ZIS` | VistaEngine, both engines | yes | + +- **Determinism without mocks:** dedicated test FileMan files / sacrificial + sub-ranges; `STDFIX`/`STDSEED` set up and tear down **real** records per test; + pinned test patient/user/parameter seed via a dedicated KIDS test-seed build + (Q6). **A result that differs across YDB and IRIS is a failure, not a warning** + (extends the `STDHARN` dual-engine work already on the m-stdlib side). +- **Coordination point:** the matrix pins **MSL module versions** (half A) and the + **contract version** (half B). When MSL tags a new release, half A re-runs to + confirm the pure modules still pass under VistaEngine before VSL bumps its pin. +- **Gated:** `make ci` on the VSL repo **requires** VistaEngine reachable; without + it L3 is untestable per the no-mocks rule (R2). + +### 8.4 Install-via-KIDS, tested in place — the embedded-first-class rule (no vendored sidecar) + +**The rule.** A green for *any* MSL or VSL library is **not** earned by running its +suites against source loaded from the working tree. It is earned only when the +library has been **packaged into a KIDS build, installed through KIDS onto the +test VistA, and its suites then run against the routines as they live in the +installed VistA namespace** — proven as an embedded, **first-class VistA +application**, never a vendored sidecar loaded beside VistA. + +This applies symmetrically to both libraries: + +- **MSL** keeps its existing bare-engine lane (LocalEngine/DockerEngine — proving + portability with zero VistA). But a *full* green additionally requires the + **`make kids` base build to install on VistaEngine via KIDS**, and the + pure-module suites (conformance matrix half A, §8) to pass **against the + KIDS-installed `STD*` routines** — not source `zload`ed for the test. Two + distributions, two proofs: library-source portability **and** first-class KIDS + install. +- **VSL** has no bare-engine lane at all — it is VistA-only — so *every* VSL green + is a KIDS-installed green by construction. + +**Why this matters (what a source-loaded test silently skips).** KIDS install is +itself part of the contract: routine-namespace mapping, the environment-check +routine (`XPDENV`, run twice), Required-Build resolution against PACKAGE #9.4, +FileMan file/DD installation, XPAR / OPTION / SECURITY-KEY component install, and +post-install hooks. A library that passes when `zload`ed from disk but fails to +*install* — a namespace collision, a missing Required Build, a DD that won't load, +an env-check that aborts — is **not deployable into VistA**. Testing the installed +package is the only thing that proves "first-class VistA application," and it is +exactly the boundary a vendored-sidecar test never exercises. + +**The install → test → back-out cycle (the gate).** `make ci` on each repo, +against VistaEngine, runs this **literal command sequence** (working names; via the +`v pkg` domain + the m-cli runner) on **both** YDB and IRIS: + +```sh +v pkg build kids/.build.json # git spec → normalized KIDS export (drift-gated, §7.2) +v pkg install --engine vista # load + run the KIDS install on VistaEngine +v pkg verify # assert every declared component present +m test --engine vista # run *TST.m against the INSTALLED routines (§8.4) +v pkg uninstall # reverse the install from the recorded manifest +v pkg verify --clean # assert engine byte-identical to pre-install +``` + +Back-out is proven, not assumed (DIBRG). Determinism (§8.2) is unchanged: +fixtures/seed data file into real FileMan, torn down per test. A divergence between +the two engines, or a non-zero exit at any step, is **red**. This is the +**KIDS-install-conformance gate** in §9. + +**Build-order consequence.** The MSL `make kids` base build and the VistaEngine +KIDS-install path are **M0** deliverables (§11) — *before* any seam crosses +TDD-red — because under this rule nothing can show green until the +install-and-test-in-place loop exists. + +--- + +## 9. Quality-Gate Coordination + +VSL is **as deterministic and gated as MSL** by adopting the identical toolchain: + +| Gate | MSL today | VSL adopts | +|---|---|---| +| Source style | `m fmt` + `m lint --error-on=error` (modern/pythonic-lower) | same | +| Tests | `^STDASSERT` `*TST.m`, TDD-red-first (safe-default stubs, never `$ECODE`) | same, **on VistaEngine, against the KIDS-installed package** (§8.4) | +| Coverage | 85%-per-module | same | +| Generated artifacts | `; doc:`→`make manifest`/`skill`/`doctest`, CI drift gates | same toolchain; **+ cross-repo contract drift gate (§5.2)** | +| **Seam-contract integrity** (boundary ①, MSL-side) | (new) **STDSNAP snapshot of the `seams` block** — a changed seam signature fails MSL CI unless `contract_version` bumped in the same commit | reads the bumped version via the cross-repo drift gate (§5.2) | +| **Error-code interface** | `errors.json` drift gate | **+ VSL `errors.json`**; every `$ECODE` a seam `raises` must exist in it | +| **DBIA conformance** (boundary ②) | n/a | **`make check-icr`** — every L4 call declared in `icr-registry.json` with a Supported ICR; no direct global access (§5.4) | +| **Citation provenance** (boundary ③) | **`make check-citations`** — every cited `doc_key` still gold + `body_sha` unchanged (§5.5) | same; a failure blocks the next contract freeze | +| **KIDS-install conformance** (the embedded-first-class rule) | (new) **`make kids` base build installs on the test VistA via KIDS and its suites pass against the *installed* routines** (§8.4) | `make kids` + KIDS **install → test-in-place → back-out → verify-clean** + DIBRG | + +**The no-duplication lint (coordination-specific):** a VSL-side check flags any +`VSL*` routine that re-implements logic available in `STD*` (heuristic: byte/string +manipulation, parsing, encoding with no `^DI`/`^XPAR`/`^XU`/`^%ZIS` call) — keeping +the seam invariant (§5.1) honest mechanically, not by review alone. + +**The seam-snapshot bump-forcer (boundary ①, MSL-side tightening).** v0.1 caught a +forgotten `contract_version` bump only *downstream*, in VSL CI. v0.2 catches it at +the source: m-stdlib keeps a **STDSNAP golden snapshot of the generated `seams` +block**, and any change to a seam entry-point's normalized record +(`args`/`returns`/`raises`) fails **MSL CI** unless the snapshot is deliberately +re-blessed **and** that seam's `contract_version` is bumped in the same commit. A +signature change therefore cannot merge without an explicit, reviewed bump — the +drift is impossible to forget, not merely detectable later. + +--- + +## 10. Change-Propagation Protocol (priority rule, "needs MSL: X") + +When VSL or a consumer needs a capability that isn't yet a portable primitive: + +1. **Stop — do not implement it in `VSL*`.** Per the priority rule, portable logic + belongs in `STD*`. +2. VSL records **`needs MSL: `** in its in-repo tracker + (`v-stdlib/docs/*-tracker.md`) — the analogue of the drivers' + `needs SDK: X`. It does **not** bump MSL. +3. The **MSL lane** picks it up, adds the primitive `STD*`-first (TDD-red→green, + manifest/skill/doctest regen), bumps the seam-contract version if it's a new + seam entry point, and **tags** a frozen-MSL release. +4. VSL **pins the new release** and consumes the primitive. + +This keeps the dependency arrow one-directional (VSL→MSL, never the reverse) and +prevents the two classic failures: portable logic stranded in VSL, and VSL forcing +half-baked MSL changes mid-stream. + +**Worked example (the S4 socket seam).** VWEB needs to frame an HTTP request → +that's `STDHTTPMSG` (pure, MSL). It needs to *send* it over TLS → that's the +`STDNET` seam bound by `VSLIO` to `CALL^%ZISTCP`. If, building `VSLIO`, we find we +need a portable "read N bytes with timeout" helper, it goes into `STDNET` +(`needs MSL: $$readn^STDNET`), tags, then `VSLIO` calls it — never a private copy +in `VSL*`. + +--- + +## 11.

Red on mismatch. | +| C2 | **Version skew at a site** — VSL installed against too-old an MSL base. | High | KIDS Required Build #11 with `DON'T INSTALL, REMOVE GLOBAL` + version minimum (§6); env-check fails fast (§7). | +| C3 | **Scope creep** — `VSL*` accretes portable logic. | Med | Seam invariant (§5.1) + no-duplication lint (§9) + the `needs MSL: X` protocol (§10). | +| C4 | **Two-writer clash** — both repos edited at once, pushes collide. | Med | One-writer-per-repo lanes (§4); cross-repo features sequential, leaf-first (§13). | +| C5 | **VistaEngine unavailable** — L3 untestable, blocks both halves of the matrix. | High | M0b stands it up as required CI infra (R2); without it, no VSL increment can verify. | +| C6 | **Engine divergence** (YDB vs IRIS) caught late. | High | Dual-engine gate from M0a onward (§8); confine the most engine-sensitive code to `VSLIO` (R1). | +| C7 | **MSL SemVer ≠ contract version confusion.** | Low | Three explicit axes (§6); the contract version is independent of library SemVer and lives in the manifest. | +| C8 | **DBIA non-conformance** — a VSL call has no Supported ICR, or uses a `Private`/retired one, or accesses a global directly. | Med | **`make check-icr` gate (§5.4):** every L4 call must be declared in `icr-registry.json` with a Supported/Controlled ICR; undeclared, retired, or direct-global = red. T-DBIA (§12) fills the pins; the gate makes shipping an unregistered call impossible. | +| C9 | **Documentation drift** — a cited VDL doc changes, is demoted from gold, or is re-ingested with a different API, silently invalidating the grounding. | High | **`make check-citations` gate (§5.5):** every cited `doc_key` must still resolve, still be `is_latest=1`, and its cited section's `body_sha` unchanged. A moved doc is red until the grounding is re-reviewed and re-blessed. | +| C10 | **Forgotten contract bump** — MSL changes a seam signature without bumping `contract_version`. | Med | **Seam-snapshot bump-forcer (§9):** a STDSNAP snapshot of the `seams` block fails MSL CI unless the version bumps in the same commit — caught at the source, not only downstream in VSL CI. | +| C11 | **Install-only-as-sidecar** — a library passes its suites against working-tree source but fails to *install* via KIDS (namespace collision, missing Required Build, un-loadable DD, aborting env-check) — i.e. it isn't actually a deployable VistA application. | High | **KIDS-install-conformance gate (§8.4):** green requires install via KIDS → test against the *installed* routines → back-out → verify-clean, on both engines. Source-loaded green is not green. | +| C12 | **Error-code interface drift** — a seam's raised `$ECODE` set changes without the registry noticing. | Low–Med | `raises` is part of the seam contract (§5.2), gated against MSL `errors.json` and a new VSL `errors.json` (§9). | +| C13 | **KIDS export non-determinism** — built transport globals embed install date/time, user, and checksums, so the same spec yields different bytes → un-diffable in git, drift gate impossible. | Med | `v pkg build` **normalizes/strips volatile fields** (invariant #2, §7.1); the committed export is the normalized form; a drift gate reproduces it (§7.2). | +| C14 | **Uninstall incompleteness** — KIDS does not natively fully uninstall (routines persist; files/DDs/params linger), so an uninstall silently leaves residue and the next install isn't clean. | High | `v pkg uninstall` reverses a **recorded install manifest** (from INSTALL #9.7 components); the gate asserts the engine is **byte-identical to pre-install** (invariant #3), not "uninstall returned OK". | +| C15 | **The `v pkg` tooling is itself unproven** — a new dependency the entire vertical rests on. | High | M0a proves every verb + the three invariants on a **one-routine throwaway package** before any seam depends on it; each verb is modular and TDD-proven. | +| C16 | **KIDS lifecycle differs YDB vs IRIS** — install/compile/back-out behave differently across engines. | Med | M0a runs the full lifecycle on **both** engines; a divergence is red (same dual-engine rule as §8). | + +(Architecture-doc risks R1–R9 still apply; these C-risks are the *coordination* +layer on top.) + +--- + +## 15. Resolved Decisions (coordination-specific) + +**All resolved 2026-06-11 — none open before implementation.** These extend, not +duplicate, the architecture doc's Q1–Q9 (all also resolved). + +| # | Question | Decision | +|---|---|---| +| CQ1 | **Where does the seam-contract manifest live?** | **DECIDED: extend `stdlib-manifest.json`** with the `seams` block — one source, one drift gate (not a separate `dist/seam-contract.json`). | +| CQ2 | **Does VSL vendor MSL for dev-time tests?** | **DECIDED: no vendoring** — load the pinned MSL base on VistaEngine (consistent with §6). | +| CQ3 | **Contract version granularity?** | **DECIDED: per-seam `contract_version`** — a VSL adapter pins only the seam it uses. | +| CQ4 | **Who owns `VistaEngine`?** | **DECIDED: the m-cli runner** (it owns the other transports), driven by the `v pkg` verbs (platform CQ2). | +| CQ5 | **Does MSL's KIDS base ship pure modules only, or also the seam stubs?** | **DECIDED: pure modules + the side-effect seam entry points (signatures).** The seams are real `STD*` entry points VSL overrides via adapter dispatch; both ship in the MSL base. | +| CQ6 | **Single VSL package or per-seam split?** | **DECIDED: single VSL base build v1** (matches architecture Q2); split only under install-footprint pressure. | +| CQ7 | **Generate a `dist/namespace-registry.json` collision gate?** | **DECIDED: yes** — a fourth tag→registry→gate triple (`VSL*`/`^VSL(`/file #s/params/keys/options vs the FileMan-470 + KIDS-196 lists), turning the point-in-time check into a re-runnable gate. Lands by M5 (packaging), where the names firm up. | +| CQ8 | **KIDS build manifest — generated or hand-authored?** | **DECIDED: generated** — the component list (routines, file #s, params, keys, ICRs from `icr-registry.json`) is generated where possible; the install→test→back-out gate (§8.4) is the backstop for anything the generator misses. | +| CQ9 | **KIDS build-spec format + ownership?** | **DECIDED: the `v pkg` domain owns the `kids/*.build.json` schema + verbs; each repo owns its own spec** — mirrors "MSL owns the seam contract, VSL owns its adapters." | +| CQ10 | **Commit the assembled export, or regenerate in CI only?** | **DECIDED: commit the normalized export** under `dist/kids/` for reviewable diffs + a reproduce-drift gate (the `dist/`-artifact model, §7.2); CI regeneration is the gate, not the source. | + +--- + +## 16. Definition of Done + +The MSL⟷VSL integration is **done** when: + +1.

All four seam gates are green and wired into CI: the **cross-repo contract + drift gate** (§5.2), the **MSL-side seam-snapshot bump-forcer** (§9), the + **`make check-icr` DBIA-conformance gate** (§5.4), and the **`make + check-citations` provenance gate** (§5.5). +4. `STD*` and `VSL*` install **once** as shared KIDS base builds; a consumer + (`VWEB`) installs via **Required Builds** with **zero duplicated routines**, and + KIDS refuses a too-old base (C2 proven). +5. The **`VWEB` end-to-end smoke test** (M6 / architecture §9) is green on both + engines. +6. Coverage (85%), fmt/lint, manifest/skill/doctest drift, and the **KIDS + install → test-in-place → back-out** gate (§8.4) are green on both repos; + `icr-registry.json` is complete (every `VSL→L4` call has a pinned Supported + ICR — T-DBIA done) and every entry carries a verified citation `body_sha` (§5.5). +7. The **`v pkg` lifecycle tooling** (`unpack/build/check` + `install/verify/ + uninstall`) is modular and TDD-proven, with its three invariants — round-trip, + deterministic build, reversible install — green on **both** engines (§7.1), and + conforms to the `v` CLI contract/registry ([`v-cli-platform.md`](v-cli-platform.md)). +8. **Every repo's KIDS package is version-controlled as diffable source** (a + declarative build spec + routines), and `v pkg build` reproduces the committed + normalized export under a drift gate (§7.2) — no opaque transport-global blobs. + +--- + +## 17.

Fully decoupled but +more moving parts. See [CQ1](#10-open-questions).)* + +--- + +## 4. The command-surface contract (per domain) + +Built on **`clikit`** — the shared Go CLI conventions every toolchain binary already +honors: `--output text|json|auto`, a versioned JSON envelope, deterministic error +objects, the **exit-code ladder** (`0` ok · `1` runtime · `2` usage · `3` +check/drift · `4` refused), plus `schema` and `version`. The `v` contract is an +*extension* of clikit, not a reinvention. + +Each domain emits a **contract manifest** `dist/v-contract.json`, **generated from +its Go command definitions** (kong), carrying: + +- `domain`, tool **SemVer**, and a **`contract_version`** (bumps only on an + incompatible command-surface change — independent of SemVer, exactly like the + seam `contract_version` in the coordination plan §6); +- every **command**: name, summary, args (name/type/required), flags, the output + **schema** ref, and the exit codes it can return. + +A **drift gate** asserts the manifest matches the actual command tree (the same +`make check-manifest` discipline that gates `dist/`). The contract is a *file*, not +a convention — so a domain's surface cannot silently drift from what it declares. + +--- + +## 5. The registry (the unified, generated surface) + +`v`'s whole command surface is **generated from the aggregate of the pinned +domains' contract manifests** into a **registry** (`dist/v-registry.json`). `v help`, +shell completion (`kongplete`, already a dep), and dispatch all read the registry — +`v` **never hand-maintains its command list**. The registry is drift-gated against +the pinned domains' contracts, so "`v` advertises a command a domain no longer +provides" is a **red gate**, not a runtime surprise. + +**Version axes (parallel to the coordination plan §6):** + +| Axis | Lives on | Bumps when | Consumed by | +|---|---|---|---| +| Domain **SemVer** | the domain repo's tags | any release | `v`'s go.mod pin | +| **`contract_version`** | the domain's `dist/v-contract.json` | command surface changes incompatibly | the registry drift gate | +| **Registry pin set** | `v`'s `go.mod` + `dist/v-registry.json` | `v` adopts a new domain version | `v` users | + +--- + +## 6. The shared Go template + `v new ` + +A **`v-tool-template`** — the tooling parallel of `~/claude/templates/python` and +`m new` — scaffolds a new domain repo with everything standardized from line one: +`clikit` wired, the contract-manifest generator, registry registration, the +conformance suite (§7), Makefile gates (fmt/lint/test/coverage/`check-manifest`), +and the JSON-envelope output plumbing. **`v new `** emits it. This is what +makes "a Go library of VistA utility functions" a *standardized* library rather +than a pile of bespoke CLIs — every domain is born with the same contract, +registry hook, and quality gates. + +--- + +## 7. Conformance + the plain-language gate + +Every domain ships (from the template) a shared **conformance suite**: + +1. **Contract drift** — the `dist/v-contract.json` matches the actual command tree. +2. **Envelope conformance** — output validates against the clikit schema; the + exit-code ladder is honored. +3. **Plain-language lint** (on-brand, the family's reason to exist) — **no domain, + command, or flag name may contain vista-ese**: `fileman`, `kids`, `xpar`, + `mailman`, `taskman`, `duz`, `^%zis`, `dic`, `die`, … A leak = **red**. This + mechanically enforces §2 as the family grows, so no tool ever re-exposes the + insider terms the platform exists to hide. + +--- + +## 8. Relationship to the rest of the stack + +- **`clikit`** is the foundation — the `v` contract/registry extends it; don't + reinvent the envelope, output modes, or exit codes. +- **The m-cli `VistaEngine` transport** — `v-*` tools that touch a live VistA should + drive it through the **same transport abstraction** (`DockerEngine` / `SSHEngine` + / a live VistA) the m-cli runner already owns, so every tool reaches the engine + one uniform way. `v pkg`'s install/uninstall lifecycle drives Kernel's KIDS + routines over this transport. +- **`v-*` Go tools vs `V*` M packages — different layers, don't conflate:** + +| | `v db` (Go, host) | `VSLFS` (`V*`, M, in VistA) | +|---|---|---| +| Runs | on the developer's host | inside the VistA engine | +| Is | a developer CLI that *talks to* FileMan from outside | the seam adapter that *binds* `STDFS` to FileMan | +| Audience | a developer at a terminal | M code calling the seam | +| Lifecycle | a `v` domain release | a KIDS-installed routine | + + They are complementary — the `v-*` tools are often *used to develop and test* the + `V*` packages — but they are not the same thing. + +--- + +## 9. First domain: `v pkg` (the KIDS lifecycle) + +Repo **`v-pkg`** (renamed from `m-kids`). It already ships the **offline** half as +pure Go (`decompose` / `assemble` / `roundtrip` / `canonicalize` / `parse` / +`lint`, byte-identical port of XPDK2VC); the platform adds the **live lifecycle** +(`build` / `install` / `verify` / `uninstall` / `status`) driving Kernel's existing +KIDS routines over the m-cli transport — **no new MUMPS package**, just Go +orchestration of `^XPDI…`. This is **M0a** of the coordination plan and the **first +proof of the whole `v` platform**: the determinism ledger there (§12.1) becomes +literal `v pkg` invocations — `v pkg build && v pkg install && … && v pkg uninstall +&& v pkg verify` — on both engines. + +--- + +## 10.

The empirical signal is the *entry reference* — every +`tag^routine` call site in the corpus.

The functions VistA *reinvents* most (JSON, string ops, encoding, +structured logging) are **exactly m-stdlib's charter** — and several +(base64/hex, CSPRNG, TOML, semver, UUID) fill **genuine gaps where VistA has +essentially nothing**. + +--- + +## 2. Why this matters for m-stdlib + +m-stdlib's reason to exist is "fill the highest-impact gaps in M's standard +library without reinventing what already works." To honor that, we must know +*what already works and is already used* in the largest M codebase on earth. +This report is the objective check: it tells us which de-facto VistA functions +m-stdlib must **defer to** (and never duplicate), and which categories VistA +**reinvents per-package** (and therefore m-stdlib should **centralize**). + +--- + +## 3. Methodology & data provenance + +**Corpus.** `~/projects/vista-meta/vista/vista-m-host/Packages/**/Routines/*.m` +— the FOIA VistA M distribution, the same routine set the VEHU education +instance runs. 39,330 `.m` files, 4,138,428 lines, across 100+ package +directories. + +**Primary metric — the entry reference.** In M, code reuse is expressed as +`tag^routine` (call a labeled entry point in another routine) and `$$tag^routine` +(extrinsic function). We extracted every token matching +`[%A-Za-z][A-Za-z0-9]*\^%?[A-Za-z][A-Za-z0-9]{0,7}` — i.e. an alphanumeric +*tag*, a caret, and an alphanumeric *routine*. Requiring alphanumerics on +**both** sides of the caret excludes bare global references (`^DPT(`, +`^%ZOSF`), which begin with the caret. This yields **529,055** call sites and +**94,736** distinct targets. + +**Three ranking signals per function:** + +- **Calls** — raw occurrence count (how *often* it's invoked). This is + "frequency" in the literal sense the request asked for. +- **Caller routines** — distinct `.m` files that reference it (how *widely*). +- **Packages** — distinct package directories that reference it. **This is the + de-facto-library signal:** a function called by 90+ packages is a shared + library; one called by 1 package (even thousands of times) is internal + plumbing. + +**Why breadth matters.** Raw frequency alone is misleading. `EN2^NURCCPU2` +has 1,608 call sites — but **all in 1 package** (Nursing): it is internal glue, +not a library. `$$NOW^%DTC` has fewer raw uses than some, yet is called by +**114 packages**: it is unambiguously de-facto-standard. The report ranks the +top-200 table by frequency (as requested) but reports breadth in every row so +plumbing is distinguishable from library. + +**Grounding.** Library identities are confirmed against the **vdocs GOLD +corpus** and the actual routine headers: + +- `$$GET1^DIQ` is the documented FileMan DBS field-read API — *VA FileMan 22.2 + Developer's Guide* §Example 3/5 (`documents/gold/consolidated/DI/di_dg/body.md`); + the Pharmacy Reengineering API manual even documents downstream calls as + "the VA FileMan DBS call `$$GET1^DIQ`" + (`documents/gold/consolidated/PSA/psa_api/body.md`). +- `XLFSTR` / `XLFDT` are the Kernel string and date/time function libraries — + routine headers: `XLFSTR ;ISC-SF/STAFF - String Functions ;;8.0;KERNEL` and + `XLFDT ;ISC-SF/STAFF - Date/Time Functions ;;8.0;KERNEL`, both carrying *"Per + VHA Directive 2004-038, this routine should not be modified"* — the literal + marker of a frozen, canonical library. +- `XPAR` is Toolkit Parameter Tools — `XPAR ; SLC/KCM - Parameters File Calls + ;;7.3;TOOLKIT` and *XT\*7.3\*26 Parameter Tools Supplement* + (`documents/gold/consolidated/XT/xt_pdd/body.md`). + +**Known caveats (stated for honesty):** + +1. **String-literal false positives.** Six "functions" tied at 342 calls — + `JAN^FEB`, `MAR^APR`, `MAY^JUN`, `JUL^AUG`, `SEP^OCT`, `NOV^DEC` — are not + calls. They are fragments of the caret-delimited month literal + `"JAN^FEB^MAR^APR^MAY^JUN^JUL^AUG^SEP^OCT^NOV^DEC"`, which appears **342 + times verbatim** across the corpus (itself a copy-paste finding — see §6). + They are **excluded** from the ranked table; the table therefore lists the + top **194** true entry references. +2. **`$J` is not reinvention.** `$JUSTIFY` is a native MUMPS intrinsic; using + it for right-justification is idiomatic, not a failure to use a library. + §7 treats it accordingly. +3. **FileMan editor internals.** Tags like `F^DIE17`, `OUT^DIE17`, `Z^DIE2`, + `QQ^DIEQ` are FileMan's own scrolling-editor engine cross-referencing + itself. They have high counts but narrow breadth (≤26 packages) because they + are mostly invoked from FileMan-generated compiled INPUT templates. They are + shown but flagged "(internal)". + +--- + +## 4. The de-facto VistA standard library (namespace rollup) + +Summing **all 529,055** call sites by provider namespace (not just the top +200) gives the objective shape of VistA's de-facto library.

calls**; 69 are intra-package plumbing +(<10 packages) carrying 34,933 calls. The library/plumbing split is visible at +a glance by reading the **Pkgs** column. + +--- + +## 6. Redundancy & copy-paste analysis + +The request asked specifically for the *amount* of redundant/repetitive/ +copy-paste code. Three objective probes: + +### 6.1 Exact-duplicate routine bodies + +Hashing every routine body (md5 of all lines after the first) finds **72 +groups of byte-identical routines covering 166 routines** — i.e. ~0.42% of the +corpus is a literal whole-file copy of another routine. **This is low** — +VistA's redundancy is *not* primarily at whole-file granularity. The exact +dupes that do exist are mostly FileMan-generated compiled templates and a +handful of namespaced clones. + +### 6.2 Line-level copy-paste (the real redundancy) + +The redundancy lives at the **line/idiom** level. The single most-repeated +non-trivial code line in all of VistA appears **2,644 times**: + +``` +S X=DG(DQ),DIC=DIE +``` + +and an entire **cluster of ~15 lines from FileMan's scrolling editor engine +(`DIE17`/`DIEQ`/`DIE0`/`DIR2`) each recurs 820–860 times.** These are +**machine-generated** — FileMan emits the same boilerplate into every compiled +INPUT template — so they are "copy-paste" in effect but generated by design, +not hand-duplicated. They explain why the `DIE17` internal tags rank so high in +§5 with narrow breadth. + +### 6.3 The month literal — hand copy-paste in the wild + +The caret-delimited constant +`"JAN^FEB^MAR^APR^MAY^JUN^JUL^AUG^SEP^OCT^NOV^DEC"` appears **342 times +verbatim** across hundreds of routines — a textbook hand-copied constant that, +in a modern codebase, would live once in a library (`$$month^…`). It is the +cleanest single illustration of "developers paste the same data because there +is no shared home for it." + +**Redundancy verdict:** whole-file duplication is rare (166 routines, 0.42%); +the dominant redundancy is (a) generated FileMan template boilerplate and +(b) hand-pasted small idioms/constants. The latter is the category a modern +stdlib eliminates. + +--- + +## 7. Reinvention analysis + +"Reinvented instead of using a built-in that already exists." Measured cases, +each with objective numbers: + +### 7.1 Case conversion — `$TR` instead of `$$UP^XLFSTR` + +`$$UP^XLFSTR` is *literally* `Q $TR(X,"abc…xyz","ABC…XYZ")` (confirmed in the +source). Yet: + +| Approach | Count | +|---|---:| +| Routines using the library `$$UP^XLFSTR` | 1,306 | +| Routines with a hand-written lowercase-alphabet literal in `$TR` | **404** | +| Occurrences of the explicit `$TR(x,"a…z","A…Z")` uppercase idiom | 529 | + +≈**24% of all uppercasing in VistA is reinvented** verbatim rather than +calling the one-line library function that does exactly the same thing. + +### 7.2 The library function nobody uses — `$$SPLIT^XLFSTR` + +`SPLIT^XLFSTR` exists in Kernel (split a string by delimiter into a var list) +and has **0 callers** in the entire corpus. Developers instead hand-roll +`$PIECE` loops everywhere. A library function that is undiscoverable is +functionally equivalent to one that doesn't exist — a key lesson for m-stdlib's +discoverability tooling. + +### 7.3 JSON — reinvented per package (the headline reinvention) + +VistA's Kernel ships a canonical JSON encoder/decoder: `XLFJSON` / +`XLFJSOND` / `XLFJSONE`. Despite that, **the corpus contains 26 distinct +`*JSON*` routines and 24 distinct JSON entry-point targets, totaling 2,643 +JSON-build call sites** — each package rolling its own: + +| Namespace | JSON routines | Package | +|---|---|---| +| `XLFJSON*` | `XLFJSON`, `XLFJSOND`, `XLFJSONE` | Kernel (the *official* one) | +| `SDESJSON`, `SDES2JSON`, `SDESBUILDJSON`, `SDEC…JSON` | 8+ | Scheduling (VSE) | +| `VPRJSON*` | `VPRJSON`, `VPRJSOND`, `VPRJSONE` | Virtual Patient Record | +| `HMPJSON*` | `HMPJSON`, `HMPJSOND`, `HMPJSONE` | Health Management Platform | +| `YTWJSON*`, `YSBJSON` | 5+ | Other | + +Two Scheduling JSON entries alone (`ERRLOG^SDESJSON` 1,173 calls; +`ERRLOG^SDES2JSO` + `BUILDJSON^SDES2JSO` 904 calls) make the top-200. **This is +the canonical reinvention pattern**: a general-purpose primitive (JSON) with no +*authoritative, modern, easy-to-call* home, so every team builds its own. + +### 7.4 Encoding — a genuine gap, not reinvention + +Only **6 routines** in the entire corpus mention base64/encoding primitives. +VistA effectively has **no** base64/hex library. So m-stdlib's `STDB64`/`STDHEX` +fill a real void rather than competing with anything. + +### 7.5 Honest non-finding — `$J` + +`$J(` appears 25,977 times vs 222 routines using `$$RJ^XLFSTR`.

The areas VistA *fragments and + reinvents* (JSON = 24 clones; structured logging; CSV; case-conversion as a + one-liner that 404 routines re-paste) map **one-to-one onto m-stdlib's + charter**. m-stdlib is the missing "one true home" for exactly the + primitives that have no home in VistA. + +2. **The genuine gaps validate the gap-filling mission.** base64/hex (6 + routines), regex (none), UUID (none), CSV (none), HTTP/URL (none), math + helpers (none), collections/cache (none), CSPRNG (none) — for these, + m-stdlib competes with *nothing*. It is additive, not duplicative. + +3. **Caveat — string & date are overlap zones; treat them as bridges, not + replacements.** `XLFSTR`/`XLFDT`/`%DT` are top-tier de-facto functions + (30k+ calls, 100+ package breadth). m-stdlib `STDSTR`/`STDFMT`/`STDDATE` + must (a) not silently diverge in semantics from the canonical Kernel + functions, and (b) ship explicit **FM-date ↔ ISO-8601** and + **XLFSTR-parity** bridges so a VistA developer adopting m-stdlib is never + forced to choose.

Confirmed *not* v-pkg's fault: the M0a ZZSKEL fixture fails identically. **Implication:** the recorded "M0a YDB driver-path proven on vehu" (tracker T0a.3/T0a.4/T0a.5) was actually the **raw-M-over-`docker exec`** path (sourcing the env file), not `v pkg … --engine ydb`.

Verified: STDASSERTTST **40/40 both engines**, STDFMTTST **62/62** + STDARGSTST **37/37** clean on IRIS (were crashing), STDUUIDTST **131/131** (P2 below also cleared), YDB full **2096/0**. | +| 2026-06-12 | **P1** | m-iris | `m.iris.Runner.cls` `GetOut` (output capture) | **The m-iris runner's output capture faults on wide (Unicode >255) characters.** `m-iris exec eval 'W $C(8212)'` (em-dash) → `ERROR #5540 … GetOut+2^m.iris.Runner.1`; `W $C(233)` (single byte) and ASCII are fine. `GetOut` retrieves the captured device output via an SQL function that chokes on a wide char in the result.

Surfaced on the T0b.2 IRIS leg. | **m-stdlib:** characterise + fix (run `STDUUIDTST` on IRIS, find the failing label). Lower priority than the `raises` crash. | **resolved 2026-06-12 (s9)** — STDUUIDTST now **131/131 on IRIS** (m-test-iris, isolated run) after the `raises` port. The "1 fail" was a **side-effect of the `raises` abort corrupting the harness frame**, not a real STDUUID bug (no STDUUID source change).

(b) → **m-stdlib**: make STDSEED/STDCSV's test-fixture `open` IRIS-portable (deviceparams / temp path), or guard the suites' file I/O per engine.

IRIS needs mode strings (`readonly→"R"`, `newversion:stream:nowrap→"WNS"`, `append→"WA"`, `close:(delete)→close:"D"`) and **catches `` where YDB sets `$ZEOF`**. Also `$$env^STDOS` used `$ztrnlnm` (YDB intrinsic → crash on IRIS), blocking STDFS's callout-gating. Surfaced finishing the T0b.2 IRIS leg (Variant B). | **Resolved (file I/O) 2026-06-13 (s10):** added a portable facade to **STDFS** — public `$$openRead/$$openWrite/$$openAppend` (engine-branched, `xecute`-hide the off-engine syntax so each compiler only parses its own — same trick as STDHARN's ZGOTO-in-`$etrap`) + private `readLn` (portable EOF) / `closeDelete` / `sizeIris` (`%File.GetFileSize`); writeFile finalises the last record with LF on IRIS to match YDB's stream-close (byte-identical on-disk size). **STDOS.env** got a `$system.Util.GetEnviron` IRIS arm. The 5 consumers now route through STDFS (`readFile`/`readLines`/`writeFile`/`writeLines`/`openAppend`); test fixtures (STDSEEDTST/STDCSVTST) too. **STDFSTST 50/50 BOTH engines; YDB full 2098/0 (no regression).** Gotchas hit: `'$zversion["IRIS"` parses as `('$zversion)["IRIS"` (unary `'` precedence) → use the positive `if $zversion["IRIS"` form; readonly-OPEN of a MISSING file *raises* DEVOPENFAIL on YDB (timeout doesn't catch it) so `openRead` keeps a ZGOTO trap; STDCSPRNG's binary `/dev/urandom` read keeps `(readonly:nowrap)` (NOT migrated — `nowrap` is load-bearing for `read *b`, dropping it 0/0'd YDB). | **resolved (file I/O) 2026-06-13** | +| 2026-06-13 | P2 | m-stdlib | Library-wide dual-engine sweep (post-T0b.2): 4 non-base modules still YDB-only | Ran the full pure-M stack on BOTH engines after T0b.2. **YDB (m-test-engine): 33 suites 2043/0** (the callout suites STDCSPRNG/STDCRYPTO/STDCOMPRESS/STDHTTP need their `.so`/byte-mode — the documented optional tier). **IRIS (foia/remote via `run^STDHARN`): 25 of 29 suites GREEN** — the base-17 plus **6 non-base modules already IRIS-clean** (STDCACHE 48/48, STDENV 46/46, STDLOG 62/62, STDSEMVER 99/99, STDSNAP 30/30, STDXFRM 38/38) + STDASSERT/STDHARN infra. **4 non-base modules still crash on IRIS**, each a class already solved in the base: **STDSEED** + **STDMOCK** = `do @callback@(args)` argument indirection (→ the STDCSV `xecute`-dispatch fix); **STDFIX** = `set $etrap` transaction/fixture unwind (→ the STDASSERT.raises `$ZVERSION[IRIS` try/catch fix); **STDPROF** = `$ZHOROLOG` timing (→ the STDDATE/STDUUID `$ZTIMESTAMP` arm). | **CLOSED 2026-06-13 (resume session): all 4 fixed.** STDPROF (`$ZTIMESTAMP` arm + an undef-safe min/max — M has no boolean short-circuit, so `'$data(x)!(e` on IRIS-strict), STDMOCK + STDSEED (`xecute`-built dispatch — IRIS has no argument indirection), **STDFIX** (the real bug: YDB `trollback N` rolls back TO level n, IRIS rolls back n LEVELS — opposite semantics; `trollback target` → `trollback 0` `` on IRIS; engine-split to `trollback $tlevel-target`).

IRIS forbids `TSTART` only when it appears *lexically inside* a `try{}` or an `xecute`'d string — **not** when reached through a `do`-chain. Proven: `$$f()` where `f` does `tstart`, called from inside `try{ … }`, works (tl=1). So STDHARN-run suites (`try { do RUN^STDHARN }` → … → `do with^STDFIX` → `tstart`) are fine; STDFIXTST is **28/28 via the runner** after the STDFIX `trollback`-semantics fix above. The whole "runner / journaling" investigation was a red herring — the only real bug was STDFIX's YDB-vs-IRIS `TROLLBACK n` semantics. Minor true caveat: `m-iris exec eval 'tstart …'` (the Eval path `xecute cmd`) still can't `tstart` because the cmd is `xecute`'d — but that's a rare one-line-eval path, not how suites run. | **no m-iris change needed.** Documented so the next reader doesn't re-chase it. | resolved (no-op) | +| 2026-06-13 | P3 | m-iris | docker/session transport truncates large output frames | While certifying T0b.2 on IRIS: the m-iris **docker** transport (`iris session` stdout-marker capture, used by `m test --docker=m-test-iris`) returns only a partial frame for large suites — STDJSONTST came back with 84 of 209 assertions, STDOSTST/STDUUID also truncated — whereas the **remote/Atelier** transport (GetOut, used against foia) returns the full frame (209/209). So per-suite IRIS validation during this work used foia/remote as ground truth and treated `--docker` only for quick compile/error probing. The earlier m-iris GetOut wide-char fix (`49a5b00`) is on the remote path; the docker session-capture path is separate. | **m-iris lane** (not m-stdlib): the `iris session` stdout-marker capture should stream/chunk large output rather than truncate.

Coverage: STDFS 69.3% per-file (dual-engine xecute-hidden arms unreachable on the YDB tier — documented exception like STDHARN 76.7%; aggregate gate unaffected); STDOS 85.1%. **(history below)** **Offline deliverables done; live loop blocked on m-ydb.** Build spec `kids/std.build.json` (MSL base = 15 ≤8-char pure modules: STDSTR/STDMATH/STDB64/STDHEX/STDFMT/STDCOLL/STDDATE/STDURL/STDARGS/STDJSON/STDTOML/STDXML/STDCSV/STDUUID/STDREGEX); `v pkg build` → **byte-identical** `dist/kids/MSL.kids` (`MSL*0.1*1`), drift-gated by `make kids`/`check-kids`. Test-in-place orchestrator `scripts/kids-test-in-place.sh` (v pkg install → load STDASSERT+STDHARN+*TST as never-shipped harness sidecar → `do run^STDHARN()` against the **installed** routines → uninstall → verify clean); harness primitives validated piecemeal on vehu (durable `exec load`; STDHARN frame contract). **m-ydb `$ydb_gbldir` blocker FIXED** (m-ydb `e5dcf85`) → the YDB driver path now reaches globals; the loop runs install→harness→… and the **harness mechanism is proven** (STDSTRTST/STDMATHTST/STDB64TST passed **in place** against KIDS-installed routines: 154 assertions, 0 failures). **YDB leg GREEN (2026-06-12 s8):** after the v-pkg streamed-install fix (`aa1991f` — install was silently installing only the first ~3 routines of a multi-routine KID; now streams the transport global in size-bounded chunks → staging global → MERGE + `EN^XPDIJ`), the full loop is green on vehu: all 15 routines install, **15/15 suites pass test-in-place (1403 assertions, 0 fail)**, reversible uninstall, verify-clean. Orchestrator now runs the harness **per suite** (a single 15-suite frame overflows the IRIS runner's output capture) and tolerates runner errors. **IRIS leg PARTIAL:** the chunked install **fully works on IRIS** (all 15 installed on foia), but test-in-place is **6/15** — blocked by (1) **discoveries P1 m-stdlib: `raises^STDASSERT` is YDB-only** (`$ETRAP`/`ZGOTO` → `` on IRIS) crashing the 6 error-path suites (STDFMT/STDDATE/STDARGS/STDJSON/STDXML/STDCSV); (2) **discoveries P1 m-iris: runner `GetOut` faults on wide-char output** (STDURL/STDREGEX); (3) **discoveries P2: STDUUIDTST 1 IRIS-only failure**. This is the first time m-stdlib suites have run on IRIS (YDB-first project). STDASSERT(9)/STDSEMVER(9) sidecar'd per the ≤8-char decision. **Update (2026-06-12 s9): `raises^STDASSERT` PORTED to IRIS** (discoveries P1 closed) — `$ZVERSION["IRIS"`→`irisRaises` try/catch, YDB byte-identical; STDASSERTTST 40/40 both engines, STDFMT 62/62 + STDARGS 37/37 clean on IRIS, STDUUID now 131/131 (P2 cleared as a raises side-effect), YDB full 2096/0. Remaining IRIS crashes are **non-raises** (discoveries P2 2026-06-12): STDJSON/XML/CSV → m-iris GetOut wide-char lane; STDSEED → IRIS file-OPEN portability. **To close 15/15: m-iris GetOut wide-char fix + STDSEED/STDCSV file-open portability**, then re-run `kids-test-in-place.sh iris` on foia and flip ☑. **Update (2026-06-13 s11): RE-BASELINE → 10/15.** The m-iris GetOut wide-char fix (`m-iris-driver@49a5b00`) WORKS on remote (STDURL/STDREGEX/STDFMT green). **No byte-mode blocker** (STDB64/STDHEX pass). 4 real m-stdlib code fixes remain — STDJSON unguarded `zgoto`-`$etrap`, STDXML null subscripts, STDCSV `@callback@` arg-indirection (won't compile on IRIS), STDDATE `now()` `$ZHOROLOG`-format — all YDB-byte-identical; STDUUID's 2 fails were collateral (no fix).

New `kids.MString`/`Subs.MRef` render M source. The Go-generated scripts ran end-to-end on vehu: install→`status=3`+`$$PING→pong`, verify→`installed=1`, uninstall→`installed=0` (reversible). `make lint` clean; race+cover green (installspec 91.4%). Decided the load approach = **direct `^XTMP` populate** (zero driver/SDK changes; user-chosen over a stdin transport). Next: mount as `v pkg install/verify/uninstall` verbs over the driver `Exec`. +- 2026-06-12 — **T0a.3 + T0a.4 install/uninstall lifecycle LIVE-PROVEN on YDB FOIA** (the plan's deepest M0a unknown). On `worldvista/vehu` (GT.M V7.0-005), drove `v pkg build`'s ZZSKEL artifact end-to-end: `EN1^XPDIL` load (the build's emitted layout matches the `GI` parser; 2 stdin answers) → `EN^XPDIJ` direct synchronous install (no prompts — `$$ANSWER^XPDIQ` returns default-NO for routine-only builds; `DUZ(0)="@"` required) → **#9.7 status = 3 "Install Completed"**, routine installed and **executes** (`$$PING^ZZSKEL()`→`"pong"`). Reversible uninstall (`^%ZOSF("DEL")` + `DIK` ×2) returned the engine to its pre-install snapshot (snapshot→install→uninstall→diff green; only the monotonic IEN counters advance). Decoded a real gotcha: an aborted install leaves a 0-node-less #9.7 entry that silently bricks both `EN^XPDIJ` and the KIDS unload — automation must purge by IEN. Full sequence + gotchas → `v-pkg/docs/kids-installation-automation.md §7.1`; §11 Q1 closed. **Next:** wire the proven sequence into Go `v pkg install/verify/uninstall` over the driver `Exec` (non-interactive-load design point), then T0a.5 dual-engine on IRIS. +- 2026-06-12 — **T0.1 live gate CLOSED.** User granted docker-exec (sandbox); `W $ZV` now confirmed on both engines: YDB `GT.M V7.1-002` (docker exec, m-test-engine) + IRIS `2026.1 (Build 234U)` (Atelier REST + docker exec, m-test-iris). The VistaEngine transport reaches a live session on both. Next live: bring up a FOIA VistA (vehu/foia — bare test engines lack KIDS) for the T0a.3 install proof. +- 2026-06-12 — T0a.3 advanced (design de-risked; live driver owed): vdocs GOLD-corpus research **closed the silent-install entry-point gap** (was an open question) — load `EN1^XPDIL`, install `EN^XPDIJ(xpda)` (ICR 2243) / `EN^XPDI`, prompt-suppress `XPDDIQ("XPZ1"/"XPO1"/"XPI1")`, phase `XPDENV`, result INSTALL #9.7 `STATUS`(#.02) + PACKAGE #9.4 patch history; `v-pkg/docs/kids-installation-automation.md` corrected (the unconfirmed `$$LOAD^XPDID`/`D INSTALL` removed). Added `v-pkg/internal/installspec` (declarative install answers + `Answers.XPDDIQ()` mapping), tested. The install **driver** + the install→verify proof remain live-only (need a FOIA engine + `%RO` confirmation of the routine signatures — the corpus has no XPD* source). Pushed (refile-v-pkg). +- 2026-06-12 — T0a.2 done (offline): `v pkg build` builds a KIDS transport global from the spec + routine source (`kids.MakeBuildPairs` — BLD+RTN+VER, volatile fields normalized: date 0, checksums stripped); the **ZZSKEL** throwaway package (one routine + spec, `v-pkg/testdata/zzskel/`) builds **byte-identical** across runs (deterministic-build invariant), golden-gated. `build` verb added → contract (`dist/v-contract.json`) + registry (`dist/v-registry.json`) regenerated. Pushed (v-pkg refile-v-pkg, v-cli main). The export's KIDS-installability is the T0a.3 live proof (FOIA via VistaEngine). Next T0a.3: `v pkg install` (load+run KIDS install on VistaEngine) — needs a live engine (docker/ssh, user gate). +- 2026-06-12 — T0a.1 done: KIDS build-spec schema + validating loader (`v-pkg/internal/buildspec`) — `kids/.build.json` (components · Required Builds #11 + action · env-check routine · ICR list), `Parse`/`Load` reject unknown fields and validate namespace/version/routine-names/actions; `testdata/zzskel.build.json` fixture. Pushed (refile-v-pkg). Next T0a.2: ZZSKEL package + `v pkg build` consuming the spec → byte-identical normalized export. +- 2026-06-12 — T0a.0 acceptance gate MET: added the contract/registry generators — `dist/v-contract.json` (v-pkg §4, reflected from the kong tree via clikit.BuildSchema; `vcontract.Manifest` + `pkgcli.Contract()`) and `dist/v-registry.json` (v-cli §5, aggregates pinned domains' contracts in-process), each golden-drift-gated with `make contract`/`registry` (+ `check-*`). With `v pkg ` working + plain-language lint green, all three gate criteria pass. Pushed (v-pkg refile-v-pkg, v-cli main). Remaining is cleanup only (v-tool-template population, tag/merge/pin, shared-clikit extraction). +- 2026-06-12 — T0a.0 repos wired: m-kids→**v-pkg** GitHub rename done (refile-v-pkg pushed); umbrella repo created and corrected to **v-cli** (binary `v`, parallel to m-cli/m), pushed to `main`; **v-tool-template** created (empty). Remaining: contract/registry generators + drift gates, populate v-tool-template, merge refile-v-pkg + tag v-pkg + pin it in v-cli (drop the dev `replace`), and extract clikit to a shared module before the 2nd domain. +- 2026-06-11 — T0a.0 started: refiled m-kids→**v-pkg** (module/binary/dir renamed; 9 offline verbs extracted to an importable `pkgcli.Commands`, byte-identical; branch `refile-v-pkg` pushed). Stood up the **`v` umbrella** (static-pinned: imports v-pkg, mounts `v pkg ` in-process via dev `replace`; **`v pkg roundtrip` green end-to-end**) + **`v new`** (rejects vista-ese, scaffolds a domain) + the **plain-language lint** conformance gate (walks the whole surface; green). `v` is git-init'd locally (push pending the gh-created `v` repo). Discovery: multi-domain in-process composition needs clikit extracted to a shared module (one domain reuses v-pkg/clikit). Remaining: contract/registry JSON generation, v-tool-template repo, the GitHub create/rename (user gh ops, sandbox-blocked for me). +- 2026-06-11 — T0.1 substrate built on the **m engine-driver contract** (decided integration = subprocess + JSON envelope, driver-contract §2/§11; NOT in-process import). Landed across repos: m-ydb SSH `remote` transport + `ydbdriver` facade (contract §3 amended); m-iris `irisdriver` facade (live-validated); **`m-driver-conformance`** gate built in m-driver-sdk (both drivers 16/16 — caught + fixed real drifts: m-iris version shape, doctor envelope/exit via clikit `ResultExit`); m-cli **`VistaEngine`** (driver-backed engine) + `m vista status|exec`. **IRIS live-green** end-to-end (`m vista status --engine iris` → real m-test-iris banner). YDB path code-identical + unit-green; live FOIA-vehu run owed (docker/ssh sandbox-blocked). m-cli on branch `t0.1-vista-engine`. +- 2026-06-12 (s3) — **tracker reconciled to reality.** m-iris closed the T0a.5 IRIS driver-path gap (`33019b7` on `m-iris-driver`, untagged): the `exec` axis is wired (`exec load/run/eval` in `internal/remote.Transport` · `Load` `.int` docname · runner `W`→`^mIrisRun(rid,"out")`→`ExecResult.Stdout`). T0a.5 row was stale ("blocked on m-iris") — corrected: the driver fix is IN; only the end-to-end `v pkg … --engine iris` run on foia + the ☑ flip remain. v-pkg unchanged (done). Remaining org-wide: (A) close T0a.5 end-to-end; (B) v-cli registry regen (3 pkg verbs missing from `dist/v-registry.json`); (C) m/v waterline G1 gate (`m arch check` + `layer` tags) — not started. +- 2026-06-12 (s4) — **T0a.5 CLOSED → M0a DONE (dual-engine driver-path exit gate green).** Ran the v-pkg lifecycle over the IRIS DRIVER path end-to-end against **foia** (IRIS 2026.1, namespace VISTA): `v pkg install /tmp/ZZSKEL.kids --engine iris --transport remote` → `installed:true status:3`; `$$PING^ZZSKEL()`→"pong" (`m-iris exec eval`); `v pkg verify` → `installed:true status:3 ZZSKEL:true`; `v pkg uninstall` → `uninstalled:true`, post-verify `installed:false status:0 ZZSKEL:false` (reversible). All over `mdriver.Client`→m-iris `exec` (binary built from `m-iris-driver` HEAD `31fa0f6`, `meta caps` lists `exec`; commit `33019b7`). Infra recipe reused: stop vehu→start foia→kill VistA-TaskMan tree (frees community-IRIS license slots)→`_SYSTEM`/`vista123`→`meta doctor` all-green. v-pkg needed **no** code change — the s3 wiring was contract-correct. T0a.3/T0a.4 also flipped ☑ (their "remaining" Go-wiring + IRIS items are now done). Env restored (vehu up, foia stopped). Next org-wide: (B) v-cli registry regen; (C) m/v waterline G1 gate. +- 2026-06-12 (s5) — **T0b.2 started (◐): offline deliverables done; live loop blocked on an m-ydb gap; paused per user.** Built the MSL KIDS base: `kids/std.build.json` = 15 ≤8-char pure modules (STDSTR/STDMATH/STDB64/STDHEX/STDFMT/STDCOLL/STDDATE/STDURL/STDARGS/STDJSON/STDTOML/STDXML/STDCSV/STDUUID/STDREGEX); `v pkg build` → **byte-identical** `dist/kids/MSL.kids` (`MSL*0.1*1`, 12304 lines), drift-gated by new `make kids`/`check-kids`. Designed the test-in-place orchestrator `scripts/kids-test-in-place.sh`: install the base via `v pkg`, then load STDASSERT+STDHARN+the `*TST` suites as a **never-shipped harness sidecar** and `do run^STDHARN()` so the suites exercise the **KIDS-installed** library routines (not source) — uninstall + verify-clean close the loop. Harness primitives proven piecemeal on vehu (durable `exec load`+`exec run`; STDHARN `##END-HARNESS pass/fail` frame). **Two findings (discoveries.md):** (1) **P1 m-ydb** — the docker transport omits `$ydb_gbldir` (`execEnv()`→nil), so every global-accessing op (the whole KIDS lifecycle) fails `%YDB-E-ZGBLDIRUNDEF`; `v pkg … --engine ydb` fails on vehu — **and the recorded M0a YDB-driver proof was actually raw-M-over-`docker exec`** (T0a.5 row corrected). (2) **≤8-char routine names** — STDASSERT(9)/STDSEMVER(9) can't ship in the base; user chose to keep the 8-char compliance limit and sidecar STDASSERT now + rename later. **Decision: pause; user fixes m-ydb's docker env first**, then re-run both engines (IRIS leg is otherwise unblocked) and flip T0b.2 ☑. +- 2026-06-12 (s6) — **m-ydb gbldir blocker FIXED; harness mechanism PROVEN in place; new v-pkg blocker found.** Fixed the m-ydb docker `$ydb_gbldir` gap (m-ydb `e5dcf85`, branch `m-ydb-driver`: `buildTrapped` now `SET $ZGBLDIR` at runtime; TDD + `make test-it` r2.07 + live vehu — `v pkg` full ZZSKEL lifecycle green). Re-ran the YDB leg: install + `do run^STDHARN` worked and **STDSTRTST/STDMATHTST/STDB64TST passed IN PLACE** against KIDS-installed routines (154 assertions, 0 failures) — the **test-in-place mechanism is validated**. But STDHEX..STDREGEX (12 suites) crashed `ZLINKFILE` because **`v pkg install` silently installed only the first 3 routines of the 15-routine KID** (staged `ZVPKGINS` = 493 lines / ~64 KB, valid footer, only STDSTR/STDMATH/STDB64; `status:3` reported). Root cause = v-pkg's **install-as-one-mega-routine** design caps at ~64 KB (and m-ydb's docker `exec load` separately fails ~922 KB routines). Recorded as **discoveries P1 (v-pkg)**; the m-ydb gbldir P1 row marked FIXED. **Fix = re-architect v-pkg install to stream `^XTMP` via `mdriver.Client.SetGlobal` + a tiny `EN^XPDIJ` routine** (separate v-pkg session). T0b.2 stays ◐, now blocked on that v-pkg fix (both engines, same install path). Engine restored (vehu up, clean; foia never started). +- 2026-06-12 (s7) — **v-pkg streamed-install fix shipped (`aa1991f`, branch `refile-v-pkg`).** Re-architected `v pkg install`: `StageChunks` streams the transport global into a staging global `^XTMP("VPKGI",…)` in ≤40 KB routine bodies; `FinalInstallScript` verifies the staged node count (refuses on mismatch) then `INST → MERGE → EN^XPDIJ` in one process. TDD + race/vet/gofmt + contract-no-drift green. Live on vehu: the full 15-routine MSL base installs (all `$T(^STD*)=1`), the YDB test-in-place loop is **15/15 (1403 assertions)**, uninstall reversible. Also corrected an earlier mis-attribution: v-pkg always generated the correct full script — the loss was the driver staging the one giant routine. +- 2026-06-12 (s8) — **YDB leg CLOSED (15/15); IRIS leg PARTIAL (6/15) — three new blockers.** Ran the IRIS leg on foia (infra recipe: stop vehu→start foia→kill TaskMan→`_SYSTEM`/`vista123`→`meta doctor`). The **chunked install fully works on IRIS** (all 15 routines installed) — cross-engine-validates the v-pkg fix. But test-in-place is only **6/15** because the m-stdlib suites had **never run on IRIS** (YDB-first project), exposing: (1) **discoveries P1 m-stdlib** — `raises^STDASSERT` is YDB-only (`$ETRAP`/`ZGOTO $ZLEVEL` → ` raises+28^STDASSERT` on IRIS), crashing all 6 error-path suites (STDFMT/STDDATE/STDARGS/STDJSON/STDXML/STDCSV); the non-`raises` suites pass clean; (2) **discoveries P1 m-iris** — runner `GetOut` faults on wide-char (>255) output (`W $C(8212)` → ``), so STDURL/STDREGEX (most non-ASCII descriptions) error; (3) **discoveries P2** — STDUUIDTST 1 IRIS-only assertion failure. Orchestrator improved: **per-suite** harness calls (a 15-suite frame overflows IRIS GetOut) + runner-error tolerance; re-verified **still 15/15 on YDB**. Engines restored (vehu up + clean, foia stopped). **To close the IRIS leg:** port `raises^STDASSERT` to IRIS (mirror STDHARN's `$ZVERSION["IRIS"` try/catch), fix STDUUID, and the m-iris `GetOut` wide-char fix (separate lane). +- 2026-06-12 (s9) — **`raises^STDASSERT` PORTED to IRIS (discoveries P1 closed).** `raises` gets a `$ZVERSION["IRIS"` branch → new `irisRaises(captured,code)`: runs the XECUTE'd code in an ObjectScript `try { xecute code } catch ex { set captured=$ecode }`, then `use $principal` + clear `$ecode` and `goto raisesUnwound` — the shared substring-match against `errno` is engine-identical; **YDB path byte-identical** (the `if` is false on YDB). **Empirically validated through the *real* test runner (`m test --docker=m-test-iris --engine=iris`), after discovering ad-hoc `irissession` heredocs mislead — IRIS rejects `.m`/`.mac` hand-loads, so my early "`,M13,`/``" results were undefined-label artifacts, not error-clobbering.** On IRIS, try/catch leaves `$ECODE` engine-identical: `,M9,` for ``, and the full user code `,U-STDFMT-UNCLOSED-BRACE,` for a `set $ECODE` raise deep in an extrinsic chain — so no module's `raise()` needed changes. (Caveat learned: IRIS `try{}` fully suppresses even a deeper `$ETRAP`, so try/catch is the only viable unwind — an `$ETRAP`+arg-less-`quit` port faults `` on the extrinsic return, the IRIS analog of the YDB M17 that forced the ZGOTO trick.) TDD: RED = STDASSERTTST 0/0 crash on IRIS; added `tRaisesCapturesDeepUserEcode` (rqDeep→rqMid→rqRaise `set $ECODE` chain) to lock the user-code path on both engines. **GREEN: STDASSERTTST 40/40 on YDB AND IRIS; STDFMTTST 62/62 + STDARGSTST 37/37 clean on IRIS (were raises-crashes); STDUUIDTST 131/131 (discoveries P2 cleared — the "1 fail" was a raises-abort side-effect, not a STDUUID bug); YDB full suite 2096/0 (no regression); STDASSERT coverage 85.5% ≥85; fmt/lint clean; dist/ manifest regenerated.** Remaining IRIS 0/0 suites are **non-raises** (discoveries P2 2026-06-12): STDJSON/XML/CSV (zero `raises` calls) → m-iris GetOut wide-char lane; STDSEEDTST → crashes at its *first* test on `open path:(newversion):0` (IRIS file-OPEN portability), before its raises test. Branch `t0b2-msl-kids-base`. Engines restored (vehu up, foia stopped — IRIS validated via m-test-iris this session, not foia). +- 2026-06-13 (s11) — **RE-BASELINE on foia → 10/15 (MEASURE-FIRST overturned the s10 byte-mode scope).** Rebuilt `m-iris/dist/m-iris` from `m-iris-driver@49a5b00` (the GetOut wide-char fix; the prior binary predated it), brought up foia, ran `kids-test-in-place.sh iris`. **10/15** (was 6/15). **The m-iris GetOut wide-char fix WORKS on remote** — STDURL 150/0, STDREGEX 102/0, STDFMT 62/0 all green (Phase-3 wide-char DONE on the foia path). **STDB64 55/0 + STDHEX 49/0 — the byte family — PASS, so there is NO byte-mode blocker** (the s10 "STDJSON byte-mode" claim was a misdiagnosis). The 5 reds have **5 distinct causes**, diagnosed via the real driver (docker m-test-iris for compile/assert detail, foia/remote as ground truth): **(1) STDJSON** crash ` parse+12` for ALL inputs = the **unguarded `zgoto`-`$etrap`** idiom (parse+encode) — the only base module that didn't guard it like STDFS/STDHARN/STDASSERT.raises do; **(2) STDXML** crash ` myNs("")` = **null subscripts** (IRIS rejects, YDB allows); **(3) STDCSV** won't COMPILE on IRIS (`#5475` on `@callback@(curRow,.fields)` — IRIS has **no argument indirection**); **(4) STDDATE** 1 fail = `now()` reads `$ZHOROLOG` as YDB 4-comma but IRIS `$ZHOROLOG` is elapsed-seconds → year 3567; **(5) STDUUID** 2 fails were **collateral** from the crashers (source+installed both 131/131 in isolation — no fix). **Real work = 4 code fixes** (STDJSON IRIS try/catch arm · STDXML null-subscript fix [user fork] · STDCSV `xecute` dispatch · STDDATE `$ZTIMESTAMP` arm), all YDB-byte-identical, following established in-repo idioms. discoveries.md s11 rows. Engines: foia up (this session), vehu stopped — restore at close. +- 2026-06-13 (s11 close) — **T0b.2 ☑ — 17/17 test-in-place on BOTH engines.** The s11 measure-first re-baseline (10/15) understated per-suite work: each crashing suite stacked several IRIS issues exposed only as the prior one cleared. Landed, each its own commit, YDB-byte-identical: **STDJSON** — zgoto-$etrap IRIS arm; **two latent UTF-8 operator-precedence bugs** in emitUtf8 + the surrogate combine (M has no precedence; wrong on *both* engines, never caught because the old tests used literal-byte passthrough — the `\u`-escape test rewrite exposed them); empty object key → graceful `U-STDJSON-PARSE` on IRIS (user decision: IRIS prohibits null local subscripts; documented in stdjson.md + users-guide); irisParse `$ECODE`-on-failure clear; file smoke tests migrated to the STDFS facade. **STDXML** — `$$dfltNsKey()` space-sentinel for the default-namespace null subscript (user-chosen). **STDCSV** — `@callback@` arg-indirection → `xecute`-built dispatch; **+ latent STDFS `readLn` bug** (IRIS try/catch left `$ECODE` set after the EOF ``, poisoning the post-read check). **STDDATE** — `now()` `$ZTIMESTAMP` IRIS arm. **STDUUID** — `unixMs()` `$ZTIMESTAMP` IRIS arm (v7 time-prefix was loosely-monotonic on IRIS via the YDB `$zhorolog` assumption → same-second misorder). **STDOS** — full IRIS port (cwd/user/hostname via `$system.*`, cmdline/argc/arg/argv graceful-empty), and cwd switched to **`$ZDIRECTORY`** (YDB's authoritative cwd; `$PWD` was unset in vehu's `docker exec`). **STDFS+STDOS added to the base** (15→17); `v pkg build` accepts STDFS's `$ZF`; deterministic gate ✓. Re-runs: foia + vehu both `suites=17 pass=1483 fail=0`. YDB per-suite green on m-test-engine (2028/0; STDCSPRNG byte-mode suite needs the `.so`, untouched). Coverage exception: STDFS 69.3% (dual-engine, documented). Engines restored: vehu up, foia stopped. +- 2026-06-13 (s12) — **Loose ends B + C closed; G1 waterline gate built.** (B) Regenerated v-cli's stale `dist/v-registry.json` — it carried only 7 pkg verbs; v-pkg's contract gained `install`/`verify`/`uninstall` in the M0a lifecycle work (T0a.3–T0a.5), so the aggregated registry was 3 verbs behind. `make registry` (which also `go mod tidy`'d `m-driver-sdk v0.3.0` into v-cli's graph — v-pkg's `pkgcli` now imports `mdriver.Client`); full `make check` green; v-cli `chore/registry-regen-lifecycle-verbs` pushed. (C) Built the **m/v waterline G1 gate** (`m-v-waterline-adr.md` §3.2 G1, the ADR's "land first" gate): new `internal/arch` + `m arch check` in m-cli (`arch-waterline-g1`). `ResolveLayer` reads `layer` from a committed meta artifact (`dist/repo.meta.json` · `dist/v-contract.json` · root `repo.meta.json`) or `--layer`. For an `m`-layer repo it runs two arms — Go dep closure (`go list -deps -json` → fail on any `vista-cloud-dev/v-*`) + M source scan (`.m` for `^VSL*` refs); a `v`-layer repo passes trivially. Exit 3 + violation list on any m → v edge. TDD, `internal/arch` 85.7% cover, wired into m-cli's `make all`. **Proven:** m-cli self-gates clean; m-stdlib (now tagged `layer: m` here) gates clean on the M arm; v-cli falsely checked as `--layer m` flags v-pkg + v-cli (exit 3). **Resume:** tag the rest (m-driver-sdk/m-ydb/m-iris = m; v-pkg/v-cli = v) + adopt the gate in each CI; then **T0b.1 scaffold v-stdlib (layer v).** +- 2026-06-13 (s12) — **T0b.1 DONE — v-stdlib scaffolded + pushed.** Created github.com/vista-cloud-dev/v-stdlib (public, matching the m-stdlib/v-pkg/v-cli siblings; `main` `f5bbb64`). No automated scaffolder exists (the Go m-cli has no `new` verb, the legacy Python `m` is gone, `~/claude/templates/m-project/` is empty), so modeled the skeleton on m-stdlib, adapted to layer v / VSL*: `.m-cli.toml` (modern, pythonic-lower, target-engine any), `Makefile` (`check-fast` = fmt-check+lint+arch engine-free; engine-bound `test`/`coverage` stage STDASSERT from m-stdlib via `--routines`, with `ENGINE`/`DOCKER` vars), `dist/repo.meta.json` with **`layer: v`** (gated by `m arch check` → passes trivially, v→m allowed), `tests/VSLSMOKETST.m` (trivial `^STDASSERT` smoke), README + CLAUDE.md (waterline rules, TDD, dual-engine). Gotcha: `m fmt --rules` only accepts `identity|canonical`; the `pythonic-lower` style comes from `.m-cli.toml` `[fmt]` when no `--rules` is passed (mirror m-stdlib's bare `m fmt`). **Verified green:** fmt-check + lint (0 findings) + arch (layer v, clean); **VSLSMOKETST 2/2 on YDB (m-test-engine) AND 2/2 on IRIS (m-test-iris)** — empty-suite-green exit criterion met dual-engine. No `VSL*` modules yet; VSLCFG (XPAR config, binds STDENV) is first at M1/T1.2. **Next M0b step: T0b.3** (the four drift gates + `seams` block). +- 2026-06-13 (s12) — **(D) layer tags landed across all 8 ecosystem repos.** Tagged the 5 remaining repos (m-cli + m-stdlib were tagged when G1 was built; v-stdlib at scaffold): **m** = m-driver-sdk (`coordination`), m-ydb (`m-ydb-driver`), m-iris (`m-iris-driver`); **v** = v-pkg (`refile-v-pkg`), v-cli (`chore/registry-regen-lifecycle-verbs`). Each via a root `repo.meta.json` — the layer is a **repo** property, so it does NOT belong in the per-domain generated `dist/v-contract.json` (v-pkg) or aggregate `dist/v-registry.json` (v-cli); `ResolveLayer` reads root `repo.meta.json` (falling through past those generated artifacts, which carry no `layer` key). All 3 `m` repos gate **clean on the Go arm** (`go list -deps` → no `vista-cloud-dev/v-*` in closure) + M arm; the 2 `v` repos pass G1 trivially. Each committed on its current working branch + pushed. **Residual:** the gate runs locally / in each repo's `make` only — the reusable org CI workflow (ADR §3.3.2, `.github/workflows/arch-waterline.yml`) is not yet wired, so CI doesn't enforce it on push yet. Next M0b: T0b.3. +- 2026-06-14 (s12) — **Org CI workflow wired + verified live; G1 now enforced in CI.** Created the reusable `.github/.github/workflows/arch-waterline.yml` (ADR §3.3.2) and completed all activation: merged m-cli arch→main (PR#5, a merge commit that also landed the stacked T0.1 VistaEngine + SDK-dedupe — both already verified), merged the workflow→`.github` main (PR#1), and added the `arch:` caller to all 8 repos. **Two non-obvious CI findings:** (1) the workflow first used `go install github.com/vista-cloud-dev/m-cli@main`, but the **Go module proxy caches the `@main` branch→commit resolution** and lagged the fresh merge ~30 min (kept resolving the pre-merge `856065b` with no `arch check`) → switched to `git clone --depth 1 --branch ${ref}` + `go build` (exact HEAD immediately; m-cli's deps still via proxy) — PR#2, validated locally vs m-cli main `47c4e49`. (2) v-cli has a dev `replace => ../v-pkg`, which would break the Go-arm's `go list` in CI — but v-cli is layer v, so arch **skips** the Go arm (trivial pass); the m-layer Go repos have no local-path replace, so their Go-arm is CI-safe. **Verified GREEN on GitHub Actions:** v-stdlib `arch/arch SUCCESS` (chain proof: caller→reusable@main→clone+build m→`m arch check`) and m-cli `arch/arch SUCCESS` (real m-layer Go-arm). m-cli + v-stdlib callers merged to main (each also got its first/updated `ci.yml`); the other 6 callers sit on their repos' current feature branches and activate when those merge. +- 2026-06-14 (s12) — **Phase A stabilization started — m-layer landed to main; a real CI bug fixed en route.** Wrote the orchestration runbook (`docs/plans/msl-vsl-orchestration-kickoff.md`: stabilize→standardize→implement; one-session↔one-repo↔one-branch; seam-as-coupling; handoff/session-boundary rules) and began Phase A leaf-first. Landed via PR (CI green): **m-stdlib**→master (waterline + tracker + memory + runbook), **m-driver-sdk**→main, **m-ydb**→main (also lands its driver work: `$ZGBLDIR` fix, SSH remote transport, clikit ResultExit). **CI bug found + fixed:** `go-ci.yml`'s schema-check step runs `go run . schema`, which assumes m-cli's `schema` command — so **m-driver-sdk** (library, `package mdriver` → "not a main package") and **m-ydb** (driver, no `schema` verb → exit 2 under pipefail) were RED on go-ci (pre-existing, masked by stale mains). Fix: `with: schema-check: false` in their go-ci callers; both then fully green (lint+test+matrix+arch). **Phase-B item:** standardize this (every Go repo's go-ci caller sets schema-check correctly, or the drivers add a `schema` verb). **HELD (then landed — see s12 close):** m-iris. +- 2026-06-14 (s12 close) — **Phase A COMPLETE — all 8 mains canonical, gate enforcing everywhere.** Landed the v-side + m-iris on top of the m-side: **v-pkg** `refile-v-pkg`→main (the m-kids→v-pkg refile + M0a lifecycle) **+ tagged `v0.1.0`**; **v-cli** dropped the dev `replace => ../v-pkg` and pinned `v-pkg v0.1.0` (registry unchanged; G4 seam-pin satisfied) → main; **m-iris** `m-iris-driver`→main after **trivial lint cleanup** (10 golangci-lint findings — httptest `w.Write`/`io.WriteString` errcheck, two unused `cc` params in remote-unsupported lifecycle stubs, an unused test param, a comment typo; tests already green, conformance 16/16) — merged with a merge commit and the **branch kept** so continued M8 work isn't disrupted. All landings CI-green (lint+test+matrix+arch). **Dependabot:** v-pkg/m-cli/m-iris merged; m-ydb #1 sent `@dependabot rebase` (its branch predated the `schema-check: false` ci.yml fix). **Not touched (genuine pending features, not stale-main artifacts):** m-stdlib PR#1 `iris-native-backends`, m-cli PR#2 `engine-chset-byte-mode` — left for their own review/merge. **Next: Phase B** (standardize substrate) then T0b.3. +- 2026-06-13 (s10) — **File I/O made dual-engine: STDFS portable facade + 5-consumer migration (Variant B "full refactor").** STDFS (was YDB-only by design) now has public `$$openRead/$$openWrite/$$openAppend` + private `readLn`/`closeDelete`/`sizeIris`, engine-branched (`readonly→"R"`, `newversion:stream:nowrap→"WNS"`, `append→"WA"`, `close:(delete)→close:"D"`, `$ZEOF`↔``-catch), with off-engine syntax `xecute`-hidden so each compiler parses only its own arm. **STDFSTST 50/50 BOTH engines** (was 0/0 IRIS). STDOS.env got a `$system.Util.GetEnviron` IRIS arm (was `$ztrnlnm`). STDJSON/STDCSV/STDSEED/STDLOG routed through STDFS; STDSEEDTST/STDCSVTST fixtures ported. **YDB full 2098/0 — no regression**; fmt clean, lint errors=0, KIDS drift-gate ✓, dist regenerated. **KEY OUTCOME:** the file-I/O refactor makes the file layer portable but does **NOT** turn the consumer SUITES green on IRIS — they have separate non-file blockers (discoveries P2 2026-06-13): **STDJSON byte-mode parser** (`$$parse` crashes on IRIS, no file involved), **STDCSV `@callback@(args)` indirection** (crashes on IRIS even ASCII), and **wide-char descriptions** (STDCSV/STDSEED/STDLOG/STDXML → m-iris GetOut/session-capture lane). Only **STDFS** goes green on IRIS this session. Coverage note: STDFS 69.3% / STDOS 83.7% per-file (dual-engine IRIS arms unreachable on the YDB coverage tier — same documented situation as STDHARN 76.7%). **To actually green the IRIS consumer suites still needs: byte-mode portability + a portable `parseFile` callback idiom + the wide-char capture path** — all separate from file I/O.
