It answers one question — *"if this change landed, what canonical +engineering knowledge would it touch, break, or fix?"* — and it answers it +with the same evidence discipline as the rest of OpenMind. It never mutates +Git, never contacts a remote, and never writes into a single canonical table. + +--- + +## 1. Canonical Base Workspace versus Git Overlay + +The Base Workspace is everything Phases 1–6 built: Assets, immutable +Revisions, Segments, Evidence and content snapshots (Phase 2/3); the canonical +Engineering Knowledge Graph of Entities, Claims and Relations with Knowledge +Revisions and Human Decisions (Phase 5); the formal Traceability snapshot of +policy-verified trace paths, coverage, gaps and orphans (Phase 6); and the +canonical Conflicts (Phase 6). It is the single source of truth. It is written +only by ordinary ingestion, deterministic projection, explicit promotion and +governed decisions. + +A **Git Overlay** is a derived, provisional view layered *on top of* a +coherent snapshot of that Base: + +```text +Overlay = Base Workspace snapshot + + Git file delta (base → head) + + Overlay content snapshots (immutable before/after bytes) + + Overlay Segments / Overlay Evidence + + graph delta (added / modified / removed graph objects) + + derived impact (requirements, tests, traces, gaps, conflicts, risk) +``` + +The overlay may **reference** Base objects by id (`base_asset_id`, +`base_entity_id`, `base_relation_id`, `base_trace_path_id`, +`base_conflict_id`, …). It may never alter them. Every overlay-derived result +carries the coordinates that make it reproducible and falsifiable: + +```text +overlay_id +overlay_revision +base_knowledge_revision +base_traceability_run +base_policy_checksum +base Git commit +head Git commit (or worktree hash) +``` + +If you cannot name the Base coordinates a result was computed against, the +result is not trustworthy — so the model refuses to produce one. + +## 2. Git Baseline coherence + +An overlay is only meaningful if the Base graph it is compared against +actually corresponds to a known Git commit. The **canonical Git Baseline** +(`workspace_git_baselines`) is that pin. Capturing a baseline records, for one +repository, the tuple: + +```text +commit_sha, tree_sha, branch_name, head_ref, +knowledge_revision, traceability_run_id, trace_policy_checksum, +graph_projector_version, trace_engine_version, asset_state_hash +``` + +A baseline may be captured only when the repository is locally available; the +worktree and index are clean; HEAD resolves to a commit; the workspace's +active Assets under the repository have current Revisions whose recorded +source commit is coherent with HEAD and report no dirty source metadata; +canonical graph staleness reconciliation has completed; the current Knowledge +Revision and Traceability Policy checksum are known; and a current +Traceability snapshot exists (or the baseline explicitly records that none +does). A dirty worktree is never silently baselined — capture is an explicit +command. + +Overlay planning fails safely when the requested base commit does not match +the recorded baseline, with typed errors: `base_commit_mismatch`, +`base_knowledge_revision_missing`, `baseline_not_captured`, `baseline_dirty`. +OpenMind will not compute canonical Requirement impact against the wrong +commit. + +## 3. Repository discovery + +Repositories are discovered through the workspace's already-registered source +paths (machine-local, Phase 1). For each candidate path OpenMind runs +`git rev-parse --show-toplevel` (a read) to find the repository root, and +`--absolute-git-dir` / `--is-bare-repository` / `rev-parse --show-object-format` +to classify it. Discovery supports: + +* a workspace rooted directly at a Git repository; +* several registered roots pointing into the same repository (deduplicated); +* nested independent repositories; +* Git worktrees where `.git` is a file, not a directory; +* detached HEAD; +* SHA-1 and SHA-256 object-format repositories. + +OpenMind does not recurse into ignored build/vendor directories merely to +find repositories. + +## 4. Multi-repository Workspaces + +One workspace may contain several repositories (a service and its client, or a +set of microservices). Each is registered with a portable **repository key**: + +```text +git: e.g. git:. git:services/namecheck +``` + +The absolute repository root is **never** stored in the portable SQLite +database. It is resolved at run time from machine-local configuration +(`openmind/machine.py`), exactly like every other absolute source path, which +keeps the `data/` directory copyable and origin-trace-free. Deduplication of +repositories that resolve to the same Git common directory happens in +machine-local memory; only the portable key is persisted. + +A **change-set overlay** spans multiple repositories, each with its own base +ref, head ref and merge-base, but produces a single logical impact report. + +## 5. Git command security boundary + +There is exactly **one** Git subprocess boundary: `GitCommandRunner.run()` in +`openmind/git/command.py`. Every Git invocation in the entire codebase goes +through it. It: + +* uses `subprocess.run` with `shell=False` and an explicit argument list + (never a shell string); +* sets an explicit `cwd` (the repository root); +* enforces a bounded timeout and bounds captured output size; +* sets a controlled environment: `GIT_OPTIONAL_LOCKS=0`, + `GIT_TERMINAL_PROMPT=0`, `GIT_PAGER=cat`, `GIT_EXTERNAL_DIFF=` (empty), + `GIT_CONFIG_NOSYSTEM=1`, `LC_ALL=C`, and clears credential/askpass helpers; +* rejects any subcommand not on an explicit allow-list. + +**Allowed** command families (read-only): `rev-parse`, `rev-list`, +`merge-base`, `show`, `cat-file`, `diff`, `diff-tree`, `status`, `ls-files`, +`ls-tree`, `check-ignore`, `for-each-ref`, `symbolic-ref`, `check-attr`. + +**Forbidden** (rejected before spawning a process): `checkout`, `switch`, +`reset`, `restore`, `clean`, `merge`, `rebase`, `cherry-pick`, `apply`, `am`, +`commit`, `tag`, `branch`, `fetch`, `pull`, `push`, `gc`, `repack`, `config`, +`remote`, `stash`, and anything else not explicitly allowed. OpenMind Phase 7 +is a Git **reader**, not a Git operator. + +The CLI, REST and MCP surfaces never accept arbitrary Git argument arrays. +They expose only *typed operations* (resolve a ref, summarize a diff, …) that +build the argument list internally. + +## 6. Ref and object validation + +Refs arriving from a caller are validated before use. Rejected: empty refs, +refs beginning with `-` (which would be parsed as options), refs containing +NUL or ASCII control characters, and refs Git reports as ambiguous. Commit +resolution uses the option-terminated form: + +```text +git rev-parse --verify --end-of-options ^{commit} +``` + +so a hostile value can never become a Git option and a ref is never +interpolated into a shell. No Phase 7 command contacts a remote; a missing ref +or missing merge-base returns an actionable typed error +(`ref_not_available_locally`, `merge_base_unavailable`, +`possibly_shallow_clone`) and never triggers a fetch. + +OpenMind does **not** bypass Git's unsafe-repository protection: it never +writes `safe.directory`. An unsafe (wrong-owner) repository is reported as +such and the user must fix ownership explicitly. + +## 7. Merge-base behavior + +A branch or PR overlay compares the head ref against the **merge-base** of the +target branch and the head, not against the tip of the target branch. This is +the same three-dot semantics a code review uses: it isolates what the branch +*introduces* from what merely happened on the target in parallel. `merge-base` +is computed once per repository and stored on the overlay-repository row. A +commit-range overlay uses its explicit base ref directly. When no merge-base +exists locally (commonly a shallow clone), the overlay fails with +`merge_base_unavailable` / `possibly_shallow_clone` rather than guessing. + +## 8. Committed overlays + +Commit-range, branch and PR overlays operate entirely on committed objects. +Diffs are read with `git diff-tree`/`git diff` against commit SHAs; content is +read with `git cat-file --batch` without ever checking anything out. Committed +overlay Evidence stays valid even if Git later garbage-collects the object, +because the exact bytes are snapshotted into OpenMind's immutable content +store at build time. + +## 9. Working-tree overlays + +A working-tree overlay captures three layers **separately**: + +```text +staged = diff(HEAD → index) +unstaged = diff(index → worktree) +untracked = files Git does not ignore and does not track +``` + +The final "after" state is the worktree, but layer provenance is preserved on +every changed file and every piece of Evidence. Untracked files are included +only when not ignored, of a supported type, and within bounded size and count. +A deterministic **worktree hash** is computed from the HEAD commit, index +entries, staged blob hashes, and the content hashes of unstaged and untracked +files — never from timestamps alone — so an unchanged working tree produces an +identical hash and a no-op refresh. If the worktree hash differs between the +start and end of a build, the snapshot was inconsistent: the build is marked +`partial` (or retried once) with reason `working_tree_changed_during_analysis` +and is never reported as complete. + +## 10. File-change taxonomy + +Diffs are read from machine-readable, NUL-delimited Git output +(`--raw --numstat --name-status -z -M -C --no-ext-diff --no-textconv +--no-color`) — never localized human output. Supported change types: `added`, +`modified`, `deleted`, `renamed`, `copied`, `type-changed`, `unmerged`, +`submodule`, `unknown`. A working tree with `unmerged` entries cannot produce a +reliable impact report; it returns `working_tree_unmerged` rather than guessing +conflict contents. Commit metadata is bounded to SHA, parent SHAs, subject and +timestamp; author email addresses are not persisted by default. + +## 11. Rename and copy behavior + +Rename (`-M`) and copy (`-C`) detection is on by default and can be disabled +explicitly. Each renamed/copied file preserves `old_path`, `new_path` and the +similarity score. A **pure rename** (100% similarity, blob unchanged) is +reported as a *path change*, not as if the implementation changed — it may +still affect path aliases, package/module identity, build configuration and +source references, but it does not fabricate a modified method. Only files +whose parser-relevant content or logical path actually changed are re-parsed. + +## 12. Binary, symlink, submodule and Git LFS handling + +* **Binary**: detected via the diff's binary marker and a NUL-byte probe. + Recorded with hashes and change metadata; never passed to a text parser or + an embedding model; never given fake line ranges. +* **Symlink** (mode `120000`): the link *target text* is stored as the blob + content; the link is never followed; `is_symlink=true`. +* **Submodule** (mode `160000`): the old/new submodule commit is recorded; the + content is opaque; OpenMind never enters or fetches the submodule. +* **Git LFS**: a standard LFS pointer is detected structurally + (`version https://git-lfs…`, `oid sha256:…`, `size …`). The pointer's oid + and declared size are recorded (`is_lfs_pointer=true`); the actual LFS object + is never downloaded. + +Each of these is honest about being unanalyzable — they contribute `unknown` +risk, not a false clean bill. + +## 13. Immutable Git Evidence + +Every changed file's before and after bytes are snapshotted into the existing +content-addressed store (`content_store.put`) at build time. Overlay Evidence +(`git_overlay_evidence`, id prefix `oev_`) cites a range within one side of one +file via a locator: + +```json +{ "kind": "git-blob-range", "repository": "git:services/namecheck", + "overlayId": "ov_…", "overlayRevision": 2, "side": "after", + "commit": "abc123…", "path": "src/main/java/NameCheckService.java", + "startLine": 120, "endLine": 156, + "symbol": "NameCheckService#execute(Request)" } +``` + +Working-tree Evidence uses `kind: "git-worktree-range"` with a `worktreeHash`, +a `baseCommit` and a `layer` (`staged`/`unstaged`/`untracked`). Rules: paths +are repository-relative; no absolute path enters portable SQLite; content is +recoverable from the immutable blob store; committed Evidence survives Git GC; +working-tree Evidence survives later file edits; before and after Evidence have +distinct ids; quotes and content hashes are verified. **Overlay Evidence is +never accepted by canonical Candidate Promotion** — it is provisional by +construction. + +## 14. Overlay segmentation + +The deterministic parsing primitives (code segmentation, the document parser +registry, the OpenAPI/JSON-Schema/SQL parsers) are refactored to operate on a +`(logical_path, bytes, media_probe, source_metadata)` tuple rather than +requiring a live filesystem path, so an overlay can parse a blob that was never +checked out. No parser logic is duplicated. Only added, modified, meaningfully +renamed, relevant copied, and supported working-tree files are parsed; deleted +files reuse their before-side Base/Git snapshot segments. Changed segments are +classified `added | modified | deleted | moved | context-changed | unchanged`. +A segment is `modified` when a changed line range intersects its source range +or its content hash changes — so an edit to one Java method does not mark every +method in the file modified; symbol identity is preserved where possible. + +## 15. Overlay vector indexes and Base search composition + +Overlay changed content is embedded into per-overlay collections +(`overlay_code_`, `overlay_documents_`, `overlay_knowledge_`). +Unchanged Base chunks are never copied. **Composed search** searches the +overlay changed content and the Base content, then masks Base hits that belong +to deleted / modified / renamed-old / type-changed paths (the overlay's version +supersedes them), preserves Base hits for unchanged files, fuses results +deterministically, and labels every hit `base` / `overlay-before` / +`overlay-after`. The response is sectioned (`code`, `documents`, `knowledge`) +and reports `maskedBaseHits`. Existing Base search commands and MCP tools are +unchanged. Closing or deleting an overlay drops its collections through the +existing bounded, interruptible vector-drain path, so responsive deletion, +in-flight-drain protection, the startup janitor and deleting-workspace +protection are not regressed. + +## 16. Overlay graph deltas + +The overlay projects a graph **delta** by running the same deterministic +projector over the before and after states of changed content and diffing the +results. Entity delta types: `added | modified | removed | renamed | +unchanged | unknown`. Examples: a new Java method → *added* code-symbol; a +deleted method → *removed* code-symbol; a renamed file with the same method → +*modified* binding/path (not removed+added); an OpenAPI `POST`→`PUT` → +*removed* old Interface + *added* new Interface; a changed config value → +*modified* Configuration fact; a changed SQL column type → *modified* +Database-Object fact. Relation deltas cover only structurally generated +relations (`contains`, `calls`, `configures`, `publishes`, `consumes`). The +model is **never** used to infer new `implements` / `refines` / `verifies` +relations, and overlay deltas are never written into canonical graph tables. + +## 17. Virtual graph composition + +A read-only `GraphView` port (`openmind/ports/graph_view.py`) exposes the graph +read surface (`get_entity`, `list_entities`, `get_claim`, `get_relation`, +`list_relations`, `neighbors`, `evidence_for_relation`). `CanonicalGraphView` +wraps the Phase 5 store and returns byte-identical results to today's canonical +reads. `OverlayGraphView` composes the Base view with the overlay delta: + +```text +Base active object + added delta + modified delta − removed delta + = virtual overlay graph +``` + +No Base row is changed; removed Base objects disappear only from the virtual +view; modified objects keep a link to their Base object; new overlay entities +use overlay ids and canonical-key *candidates*; every returned node discloses +its origin (`base` / `overlay`). Phase 5 traversal and Phase 6 trace/conflict +readers accept a `GraphView` where practical, so the same code computes both +canonical and virtual results; canonical call sites keep using +`CanonicalGraphView`. + +## 18. Requirement and Test impact + +For each directly affected canonical implementation / interface / data / +workflow / configuration Entity, the analyzer uses **reverse formal +traceability** (Phase 6) to collect affected Requirement roots and their +current Base trace paths, then revalidates those traces in memory against the +`OverlayGraphView` and compares before/after. Requirement impact types include +`implementation-changed/removed/added`, `interface-changed`, +`configuration-changed`, `data-model-changed`, `trace-weakened`, +`trace-broken`, `trace-created`, `trace-unchanged`, `ambiguous-impact`. An +added code symbol is **never** reported as implementing a Requirement unless a +valid overlay relation supports it. + +Test impact produces two distinct groups: **impacted tests** (canonical Test +Cases / Results whose Base trace paths include changed or removed objects) and +**recommended tests** (active canonical Test Cases connected to impacted +Requirements or implementation targets, even if the test itself did not +change). Tests are never executed and a recommended test is never claimed to be +sufficient verification. + +## 19. Projected Gaps + +Overlay trace paths are **not** persisted into canonical `trace_paths`. The +analyzer compares the Base formal trace with the virtual overlay formal trace +and records derived impact: paths introduced / removed / weakened / +strengthened, new stale paths, new/resolved ambiguity. Projected **Gap** +impact is `introduced | resolved | persisting | unknown` (e.g. a deleted test → +*introduced* missing-test; a deleted sole implementation → *introduced* +missing-implementation; an added valid test relation → *resolved* missing-test). +A projected Gap is never inserted into canonical Gap tables. + +## 20. Projected Conflicts + +The existing deterministic Conflict detectors (Phase 6) run against **only the +affected subjects** in the `OverlayGraphView` — never the whole virtual graph. +Results are classified `introduced | resolved | persisting | modified | +unknown` (e.g. config `3000`→`5000` while a Requirement still says `3000` → +*introduced* specification-code conflict; OpenAPI `PUT`→`POST` matching a +Requirement → *resolved* HTTP-method conflict; a binary interface file → +*unknown*). Projected Conflicts remain overlay records; they are never inserted +into canonical `engineering_conflicts`, and no conflict-governance action is +available until the change is actually merged and canonical graph +synchronization confirms it. + +## 21. Deterministic risk policy + +Risk is **rule-based, never model-scored**, over the ordered scale +`critical > high > medium > low > info` with a separate `unknown`. Summarized +rules: *critical* — an authoritative Requirement deleted, a verified +Requirement loses all implementation paths, an active critical Conflict gets +worse, or a new critical deterministic Conflict is introduced. *high* — a +verified Trace becomes broken, a required implementation/Interface/Test is +removed, an authoritative Interface or normative Claim changes, a high-severity +Gap is introduced, or a policy-marked security-sensitive configuration changes. +*medium* — a traced implementation/config/schema/topic changes, an inferred +relation becomes ambiguous, a medium Gap/Conflict is introduced, or a Test Case +changes. *low* — untraced implementation change, doc-only change without +canonical bindings, or a pure rename with no semantic identity change. *info* — +comment/metadata-only, new unbound documentation, or a formatting-only change +proven by normalized content equality. *unknown* — binary change, unavailable +LFS object, truncated analysis, unsupported parser, missing Base coherence, or +an unanalyzed submodule. **`unknown` is never downgraded to `low`.** + +## 22. Overlay Revision semantics + +Each overlay has its own monotonic `overlay_revision`, unrelated to the +canonical Knowledge Revision. The first successful build is revision 1; a +changed head ref or working-tree state produces the next revision; an unchanged +refresh produces none; a failed build never increments. Every report is stamped +with both the Base Knowledge Revision and the Overlay Revision. Old revisions +stay queryable until the overlay is deleted; closing preserves history; +deleting removes only overlay data. + +## 23. Overlay staleness + +The overlay's **source hash** is computed from the Git adapter version, overlay +builder version, repository ids, base/head commits and trees, merge bases, +worktree hash, raw file-change identities, before/after content hashes, Base +Knowledge Revision, Base Trace Policy checksum, graph-projector version, +trace-engine version, conflict-detector versions, and the bounded options. A +refresh with the same source hash is a no-op (no parse, no embed, no revision, +no report). When the head ref moves, only newly changed files are re-parsed and +a new revision is created. When the target Base commit or the canonical +Knowledge Revision advances, the overlay becomes **`stale`** and must be +explicitly refreshed/rebased — the old report is never silently reinterpreted +against a new Base. A changed Trace Policy checksum invalidates only Trace +impact; a changed detector version invalidates only Conflict impact; file/segment +work is reused where safe. + +## 24. Post-merge reconciliation + +OpenMind never merges a branch. After the user merges externally and updates +the canonical checkout, `overlay reconcile` verifies that the overlay head +commit is now an ancestor of (or its tree provably present in) the canonical +HEAD, that the canonical worktree is clean, and that canonical ingestion + +graph sync + staleness reconciliation + trace refresh (+ optional conflict +scan) have completed; it records the resulting Knowledge Revision and +Traceability run and links the overlay's changes to canonical Revisions. On +success the overlay state becomes `merged`. Projected overlay relations are +**never** auto-promoted — only canonical ingestion, deterministic projection +and explicit governance may alter the Base graph. + +## 25. PR Impact Report format + +The report is rendered deterministically from structured impact records — never +written by a model — as both JSON (schema `1.0.0-draft.1`) and Markdown. +Required sections: identity; baseline; head; repositories; commits; file +summary; changed files; changed segments; direct graph deltas; impacted +Requirements; impacted Interfaces/Data-Models/Configurations/Workflows; +impacted tests; recommended tests; Trace impact; Gap impact; Conflict impact; +risk summary; unknowns; limits and truncation; Evidence index. Every impact +statement carries a Base/Overlay object id, a reason, an Evidence id, a +confidence, a source side and a path/locator. The Markdown body is +byte-identical for identical overlay state (no embedded generation timestamp; +the manifest may carry one). + +The **Change Impact Packet** (`openmind impact export`) writes a deterministic, +hash-manifested directory (`manifest.json`, `summary.json`, `report.md`, and +per-record JSON-lines files) with SHA-256 file hashes, deterministic ordering, +no absolute paths, no secrets, no author emails, no LFS contents, and explicit +partial/truncation state. A standalone verifier (`python -m +openmind.impact_verify`) re-checks hashes and referential integrity. It is +**not** a Feature Evidence Packet (Phase 9). + +## 26. Compatibility guarantees + +* Canonical tables (`assets`, `asset_revisions`, `segments`, `evidence`, + `engineering_entities/claims/relations`, `trace_paths`, + `traceability_gaps`, `traceability_coverage_snapshots`, + `engineering_conflicts`) are never written by an overlay. +* Existing ingestion (`openmind ingest`, `asset add`, `document add`) keeps its + public contract and its zero-cloud-call guarantee. +* Existing graph and traceability commands are unchanged; a Base query stays a + Base query and overlay-aware queries are explicit. +* Phase 4 semantic analysis is never run automatically for changed files. +* All 43 existing MCP tools keep their names, arguments, response fields and + read-only behavior; Phase 7 adds exactly 8 read-only tools (total 51). +* `.openmind schemaVersion` stays `1.1.0`; the Knowledge Bundle stays + `2.0.0-draft.2`; the Skill Bridge stays unchanged and database-independent. +* Phase 1–6 databases migrate to v0008 without losing any data (v0008 is + purely additive). + +## 27. Testing strategy + +Focused acceptance suites (`tests/verify_git_*.py`, +`tests/verify_overlay_*.py`, `tests/verify_impact_packet.py`) build **temporary +Git repositories** in-process — no network — with invented neutral history (a +`NameCheck` service with `REQ-NC-017`, a `POST /name-check` interface, a +`timeout=3000` config, a `NameCheckService.execute` implementation, a +`NameCheckTest` and a passing result) plus feature-branch variants (method body +changed, timeout `3000`→`5000`, `POST`→`PUT`, test deleted, implementation +added, file renamed, binary contract changed) and extra fixtures for +multi-repo, working-tree layers, submodule/LFS pointers, Unicode filenames and +shallow-clone merge-base failure. Every script is registered in +`scripts/run_acceptance.py`; an unregistered `verify_*.py` fails the manifest. +Security tests assert that every command sent to the runner uses `shell=False`, +only allowed families, `-z` output, rejects `-`-leading refs, does not bypass +unsafe-repository protection, enforces the timeout and bounds output, and +contacts no remote. Isolation tests assert overlay operations change zero rows +in every canonical table. + +## 28.
