From bc23964081af8a610fc6f2cc42012e5183c9ed5b Mon Sep 17 00:00:00 2001 From: Harshit Singh Bhandari Date: Tue, 23 Jun 2026 21:41:19 +0530 Subject: [PATCH 01/60] feat(runtime): add tmux adapter package Adds backend/internal/adapters/runtime/tmux implementing ports.Runtime via the tmux CLI. Drop-in replacement for the zellij adapter on Darwin/Linux. Key design points: - Handle is a plain session id string (no pane-id split needed for tmux). - Exact-match session targeting via = prefix for kill-session and has-session. - Keep-alive shell appended to launch command so sessions survive agent exit. - send-keys -l chunked for literal text delivery (no key-name interpretation). - IsAlive distinguishes definitive-dead (missing/no-server output) from probe errors so the reaper never kills a session on a transient tmux failure. - 34 tests pass: 32 unit tests via fakeRunner seam, 2 integration tests on real tmux 3.6b (TestRuntimeIntegration, TestRuntimeIntegrationExactSessionParsing).

([]byte, error)` and `Start(env, name, args...) error`) with an +`execRunner` default, so tests inject a `fakeRunner`. The tmux binary defaults to +`"tmux"` (allow `Options.Binary` override; resolve via `exec.LookPath`). + +- **Create**: validate session id (sanitize like zellij's `SessionName`; tmux + session names must not contain `.` or `:` — those are window/pane separators — + and must be non-empty; reuse the same sanitize-to-`[A-Za-z0-9_-]`+hash approach). + Validate WorkspacePath non-empty, Argv non-empty, env keys (port + `validateEnvKeys`). Then: + `tmux new-session -d -s -x 220 -y 50 -c ` + where `` runs the agent then **execs a keep-alive shell so the tmux + session survives the agent exiting** (this is the whole reason a multiplexer is + used). Build the launch as a single shell command string passed to + `sh -c` (or the configured shell), of the form: + `export K=V; ...; export PATH=...; ; exec "${SHELL:-/bin/sh}" -i` + Reuse zellij's `wrapLaunchCommandUnix` quoting approach (single-quote each env + value and each argv word). Pass env to the agent via the exported-vars prefix + (do NOT rely on tmux `-e`, which has its own quirks). After creating, set + `tmux set-option -t status off` (hide the status bar in the embedded web + terminal). Then verify liveness via IsAlive; on failure, Destroy and return an + error (mirror zellij's create cleanup discipline). Return + `ports.RuntimeHandle{ID: }`. NOTE: tmux needs no pane-id discovery — the + handle is just the session id. Keep the handle format simple (the session id); + do NOT invent a `session/pane` split unless a consumer requires it (none does — + verify). +- **Destroy**: `tmux kill-session -t `. Treat "session not found"/"can't find + session" stderr on a non-zero exit as success (idempotent), mirroring zellij's + `deleteSessionMissingOutput`. +- **IsAlive**: `tmux has-session -t `. Exit 0 => alive. A non-zero exit whose + output says the session/server is missing ("can't find session", "no server + running", "error connecting") => definitively `false, nil`. Any OTHER error => + `false, err` (a probe failure, NOT proof of death) — this distinction matters + because the reaper feeds the lifecycle manager and must not kill a session on a + transient probe error. Mirror zellij's IsAlive contract precisely. +- **SendMessage**: send literal text then Enter. Use + `tmux send-keys -t -l ` for the literal text (the `-l` flag stops + tmux interpreting words like "Enter"/"C-c" as key names), chunked via the ported + `chunks(message, chunkSize)` helper, then `tmux send-keys -t Enter` to + submit. (Per the agent-orchestrator reference, multiline text can alternatively + go via `load-buffer -`/`paste-buffer`, but `send-keys -l` chunked is simpler and + correct — use it. Mark any simplification with a `ponytail:` comment.) +- **GetOutput**: `tmux capture-pane -t -p -S -` (the `-S -` starts n + lines back in history; `-p` prints to stdout). Then apply the ported + `trimTrailingBlankLines` + `tailLines(out, lines)`. `lines <= 0` => error, like + zellij. +- **AttachCommand**: return argv `["tmux", "attach-session", "-t", ]` (use the + resolved binary path as argv[0]) and a `nil` env block (no per-session socket dir + needed for tmux — unlike zellij's Windows ConPTY env). The terminal layer's + existing Unix `defaultSpawn` (creack/pty) will spawn this unchanged. + +## Options +```go +type Options struct { + Binary string // default "tmux" (resolved via exec.LookPath) + Shell string // default $SHELL else /bin/sh + Timeout time.Duration // default 5s + ChunkSize int // default 16*1024 +} +``` + +## Tests (REQUIRED — this is the runnable check) +1. **Unit tests** `tmux_test.go` using a `fakeRunner` (copy the struct shape from + zellij_test.go: records calls, returns scripted outputs/err).

Real end-to-end: Create a session running a + trivial command (e.g. `sh -c 'echo hello; ...'` via Argv), assert IsAlive true, + SendMessage, GetOutput contains expected text, Destroy, then IsAlive false. + Use a unique session id (incorporate the test name) and ALWAYS Destroy in a + `t.Cleanup` so a failed test never leaks a tmux session on the dev machine. + tmux 3.6b IS installed here, so this test WILL run — make it pass. + +## Constraints / definition of done +- `cd backend && go build ./... ` succeeds. +- `cd backend && go test ./internal/adapters/runtime/tmux/...` passes (unit + + integration), and `go vet ./internal/adapters/runtime/tmux/...` is clean. +- Do NOT modify any file outside the new `internal/adapters/runtime/tmux/` package. +- Do NOT add new dependencies (tmux is shelled out via os/exec; no Go module + needed). go.mod must be unchanged. +- Follow the user's hard rule: **never use em dashes** in code, comments, or commit + messages.

Keep the handle format simple (the session id); ++ do NOT invent a `session/pane` split unless a consumer requires it (none does — ++ verify). ++- **Destroy**: `tmux kill-session -t `. Treat "session not found"/"can't find ++ session" stderr on a non-zero exit as success (idempotent), mirroring zellij's ++ `deleteSessionMissingOutput`. ++- **IsAlive**: `tmux has-session -t `.

Any OTHER error => ++ `false, err` (a probe failure, NOT proof of death) — this distinction matters ++ because the reaper feeds the lifecycle manager and must not kill a session on a ++ transient probe error. Mirror zellij's IsAlive contract precisely. ++- **SendMessage**: send literal text then Enter. Use ++ `tmux send-keys -t -l ` for the literal text (the `-l` flag stops ++ tmux interpreting words like "Enter"/"C-c" as key names), chunked via the ported ++ `chunks(message, chunkSize)` helper, then `tmux send-keys -t Enter` to ++ submit. (Per the agent-orchestrator reference, multiline text can alternatively ++ go via `load-buffer -`/`paste-buffer`, but `send-keys -l` chunked is simpler and ++ correct — use it. Mark any simplification with a `ponytail:` comment.) ++- **GetOutput**: `tmux capture-pane -t -p -S -` (the `-S -` starts n ++ lines back in history; `-p` prints to stdout). Then apply the ported ++ `trimTrailingBlankLines` + `tailLines(out, lines)`. `lines <= 0` => error, like ++ zellij. ++- **AttachCommand**: return argv `["tmux", "attach-session", "-t", ]` (use the ++ resolved binary path as argv[0]) and a `nil` env block (no per-session socket dir ++ needed for tmux — unlike zellij's Windows ConPTY env). The terminal layer's ++ existing Unix `defaultSpawn` (creack/pty) will spawn this unchanged. ++ ++## Options ++```go ++type Options struct { ++ Binary string // default "tmux" (resolved via exec.LookPath) ++ Shell string // default $SHELL else /bin/sh ++ Timeout time.Duration // default 5s ++ ChunkSize int // default 16*1024 ++} ++``` ++ ++## Tests (REQUIRED — this is the runnable check) ++1. **Unit tests** `tmux_test.go` using a `fakeRunner` (copy the struct shape from ++ zellij_test.go: records calls, returns scripted outputs/err). Cover: command ++ args for Create (new-session + status off), Destroy, IsAlive (alive / missing => ++ false,nil / transient error => err), SendMessage (chunking + -l + Enter), ++ GetOutput (tail/trim), AttachCommand argv, session-name sanitization, env-key ++ validation, the keep-alive shell is present in the launch command, env vars are ++ exported in the launch command. ++2. **Integration test** `tmux_integration_test.go` gated on ++ `if _, err := exec.LookPath("tmux"); err != nil { t.Skip(...) }` (mirror ++ `zellij_integration_test.go`). Real end-to-end: Create a session running a ++ trivial command (e.g. `sh -c 'echo hello; ...'` via Argv), assert IsAlive true, ++ SendMessage, GetOutput contains expected text, Destroy, then IsAlive false. ++ Use a unique session id (incorporate the test name) and ALWAYS Destroy in a ++ `t.Cleanup` so a failed test never leaks a tmux session on the dev machine. ++ tmux 3.6b IS installed here, so this test WILL run — make it pass. ++ ++## Constraints / definition of done ++- `cd backend && go build ./... ` succeeds. ++- `cd backend && go test ./internal/adapters/runtime/tmux/...` passes (unit + ++ integration), and `go vet ./internal/adapters/runtime/tmux/...` is clean. ++- Do NOT modify any file outside the new `internal/adapters/runtime/tmux/` package. ++- Do NOT add new dependencies (tmux is shelled out via os/exec; no Go module ++ needed). go.mod must be unchanged. ++- Follow the user's hard rule: **never use em dashes** in code, comments, or commit ++ messages. Use periods/commas/parentheses. ++- Keep it lazy/minimal (ponytail): no speculative abstraction, no pane-id machinery ++ tmux doesn't need, no config the daemon won't set. Mark any deliberate shortcut ++ with a `ponytail:` comment naming the ceiling. ++- Commit your work on the current branch (`migrate-zellij-to-tmux-conpty`) with a ++ clear message. git author is already configured. +diff --git a/.superpowers/sdd/task-1-report.md b/.superpowers/sdd/task-1-report.md +new file mode 100644 +index 0000000..08dc462 +--- /dev/null ++++ b/.superpowers/sdd/task-1-report.md +@@ -0,0 +1,65 @@ ++# Task 1 Report: tmux Runtime Adapter ++ ++## What was built ++ ++New package `backend/internal/adapters/runtime/tmux` implementing `ports.Runtime` ++via the tmux CLI. Four files were created (no existing files modified): ++ ++- `backend/internal/adapters/runtime/tmux/tmux.go` - Runtime struct, Options, New, ++ Create/Destroy/IsAlive/SendMessage/GetOutput/AttachCommand, session-name ++ sanitization, helpers (chunks, tailLines, trimTrailingBlankLines, ++ validateEnvKeys, sortedKeys, shellQuote, buildLaunchCommand, commandError). ++- `backend/internal/adapters/runtime/tmux/commands.go` - Arg builders for all tmux ++ subcommands (newSessionArgs, setStatusOffArgs, killSessionArgs, hasSessionArgs, ++ sendKeysLiteralArgs, sendEnterArgs, capturePaneArgs, exactSessionTarget). ++- `backend/internal/adapters/runtime/tmux/tmux_test.go` - 32 unit tests via fakeRunner. ++- `backend/internal/adapters/runtime/tmux/tmux_integration_test.go` - 2 integration ++ tests gated on `exec.LookPath("tmux")`. ++ ++## Design choices ++ ++1. Handle format: plain session id string (no session/pane split). tmux needs no ++ pane-id discovery; the handle is just `ports.RuntimeHandle{ID: }`. ++ ++2. Exact session targeting: `kill-session -t =` and `has-session -t =` use ++ tmux's `=` exact-name prefix (supported by session-selection commands in tmux ++ 3.x) to prevent prefix matching ("foo" matching "foobar"). Commands that use ++ pane-targeting syntax (set-option, send-keys, capture-pane) use a plain session ++ name because they do not support the `=` prefix. ++ ++3. Keep-alive shell: `buildLaunchCommand` appends `; exec ${SHELL:-/bin/sh} -i` so ++ the tmux session survives agent exit (the whole reason a multiplexer is used). ++ ++4. Send-keys chunking: `send-keys -t -l ` with `-l` flag sends text ++ literally (tmux does not interpret "Enter", "C-c", etc. as key names). Chunked ++ via ported `chunks()` helper with 16 KB default. ++ ++5. `sessionMissingOutput` covers: "can't find session", "no server running", ++ "error connecting", "session not found". Both `killSessionMissingOutput` and the ++ IsAlive path use this to distinguish definitive-dead from probe-error. ++ ++6. `AttachCommand` returns `["tmux", "attach-session", "-t", id]` with nil env ++ (no per-session socket dir needed unlike zellij's Windows path). ++ ++7. `ponytail:` comments mark the two deliberate simplifications: ++ - send-keys -l chunked vs. load-buffer/paste-buffer (ceiling: very large ++ messages are slightly slower; 16 KB default is ample for agent prompts). ++ - PATH handling matches the zellij unix path. ++ ++## Verification output ++ ++``` ++$ cd backend && go build ./... ++# success (no output) ++ ++$ go test ./internal/adapters/runtime/tmux/... -v ++# 34 tests passed (32 unit + 2 integration with real tmux 3.6b) ++ ++$ go vet ./internal/adapters/runtime/tmux/... ++# no issues ++``` ++ ++## Concerns ++ ++None.

Pass env to the agent via the exported-vars prefix + + (do NOT rely on tmux `-e`, which has its own quirks).

Then verify liveness via IsAlive; on failure, Destroy and return an + + error (mirror zellij's create cleanup discipline). Return + + `ports.RuntimeHandle{ID: }`. NOTE: tmux needs no pane-id discovery — the + + handle is just the session id. Keep the handle format simple (the session id); + + do NOT invent a `session/pane` split unless a consumer requires it (none does — + + verify). + +- **Destroy**: `tmux kill-session -t `. Treat "session not found"/"can't find + + session" stderr on a non-zero exit as success (idempotent), mirroring zellij's + + `deleteSessionMissingOutput`. + +- **IsAlive**: `tmux has-session -t `. Exit 0 => alive. A non-zero exit whose + + output says the session/server is missing ("can't find session", "no server + + running", "error connecting") => definitively `false, nil`. Any OTHER error => + + `false, err` (a probe failure, NOT proof of death) — this distinction matters + + because the reaper feeds the lifecycle manager and must not kill a session on a + + transient probe error.

Use + + `tmux send-keys -t -l ` for the literal text (the `-l` flag stops + + tmux interpreting words like "Enter"/"C-c" as key names), chunked via the ported + + `chunks(message, chunkSize)` helper, then `tmux send-keys -t Enter` to + + submit. (Per the agent-orchestrator reference, multiline text can alternatively + + go via `load-buffer -`/`paste-buffer`, but `send-keys -l` chunked is simpler and + + correct — use it. Mark any simplification with a `ponytail:` comment.) + +- **GetOutput**: `tmux capture-pane -t -p -S -` (the `-S -` starts n + + lines back in history; `-p` prints to stdout). Then apply the ported + + `trimTrailingBlankLines` + `tailLines(out, lines)`. `lines <= 0` => error, like + + zellij. + +- **AttachCommand**: return argv `["tmux", "attach-session", "-t", ]` (use the + + resolved binary path as argv[0]) and a `nil` env block (no per-session socket dir + + needed for tmux — unlike zellij's Windows ConPTY env).

New package `internal/adapters/runtime/runtimeselect` +Define the union interface that the daemon wires and that both adapters satisfy: +```go +package runtimeselect + +type Runtime interface { + ports.Runtime // Create, Destroy, IsAlive + SendMessage(ctx context.Context, handle ports.RuntimeHandle, message string) error + GetOutput(ctx context.Context, handle ports.RuntimeHandle, lines int) (string, error) + AttachCommand(handle ports.RuntimeHandle) (argv []string, env []string, err error) +} +``` +Add a constructor that picks the backend by OS: +```go +// New returns the per-platform runtime: tmux on Darwin/Linux, zellij on Windows +// (the Windows ConPTY adapter lands in a later phase). log is used only for the +// Windows zellij socket-dir warning; nil is allowed. +func New(log *slog.Logger) Runtime +``` +- Non-Windows (`runtime.GOOS != "windows"`): return `tmux.New(tmux.Options{})`. +- Windows: replicate today's daemon.go behavior exactly — compute + `zellij.DefaultSocketDir()`, `os.MkdirAll(dir, 0o700)` and on error + `log.Warn(... "could not create zellij socket dir; spawns may fail" ...)` (guard + on nil log), then return `zellij.New(zellij.Options{SocketDir: dir})`. +- Add compile-time assertions: `var _ Runtime = (*tmux.Runtime)(nil)` and + `var _ Runtime = (*zellij.Runtime)(nil)`. + +Keep it minimal (ponytail): no Options struct, no registry, no env knobs the daemon +will not set. A plain `runtime.GOOS` switch is the right altitude (mirrors +agent-orchestrator's `getDefaultRuntime()`). + +### 2. Rewire `internal/daemon/daemon.go` +Replace the zellij-specific block (the `zellijSocketDir := zellij.DefaultSocketDir()` ++ MkdirAll + warn + `runtimeAdapter := zellij.New(...)`, currently lines ~89-99) +with a single `runtimeAdapter := runtimeselect.New(log)`. Update the nearby comment +so it no longer says "the Zellij runtime supplies..." — make it runtime-neutral +(e.g. "the selected runtime (tmux on macOS/Linux, zellij on Windows) supplies the +PTY-attach command and liveness"). Remove the now-unused `zellij` import from +daemon.go IF nothing else there uses it (check; `os` may also become unused — only +remove imports that are truly unused). `terminal.NewManager(runtimeAdapter, ...)`, +`newSessionMessenger(store, runtimeAdapter, ...)`, `startLifecycle(..., runtimeAdapter, ...)`, +and `startSession(cfg, runtimeAdapter, ...)` calls stay as-is (they take interfaces +or the union). + +### 3. Change `startSession` signature in `internal/daemon/lifecycle_wiring.go` +Change the param `runtime *zellij.Runtime` to `runtime runtimeselect.Runtime`. +Update the doc comment ("over the real zellij runtime" -> runtime-neutral). The body +is unchanged: it passes `runtime` into `sessionmanager.Deps{Runtime: runtime}` (the +union satisfies `runtimeController`) and `reviewcore.NewLauncher(reviewers, runtime)` +(the union satisfies `reviewerRuntime`). Remove the now-unused `zellij` import from +lifecycle_wiring.go if it becomes unused. + +### 4. Runtime-aware doctor check `internal/cli/doctor.go` +Today (~lines 294-308) it runs `zellij --version` and validates against +`zellij.CheckVersionOutput`/`zellij.RequiredVersion`. Make the tool check match the +selected runtime: +- Non-Windows: check for **tmux**. Resolve `exec.LookPath("tmux")`; run `tmux -V`; + report a pass with the version string (e.g. "tmux (version 3.6b)"). tmux has no + hard minimum version for our usage, so presence + version is enough — do NOT + invent a strict semver gate. If tmux is missing, report the existing failure + level the function uses for a missing tool, with name "tmux". +- Windows: keep the existing zellij version check unchanged. +Use the same `doctorCheck{...}` shape, `doctorSectionTools` section, and pass/fail +levels already in the file. Read the surrounding function to match its structure and +the exact way it shells out (it likely has a helper for running the tool). + +### 5. Runtime-aware attach hint `internal/cli/spawn.go` +Today (~lines 101-106) it prints `zellij attach ` plus a +ZELLIJ_SOCKET_DIR note. Make it runtime-aware: +- Non-Windows: print `tmux attach -t ` where `` is the tmux session + name for the session id. For this you need an EXPORTED sanitizer in the tmux + package: add `func SessionName(id string) string` to the tmux package (it + already sanitizes internally for Create — expose that same function, mirroring + `zellij.SessionName`). No socket-dir note is needed for tmux. +- Windows: keep the existing `zellij attach` hint (with the socket-dir note). + +### 6. Update `internal/daemon/wiring_test.go` +It currently calls `zellij.New(zellij.Options{})`, `startSession(cfg, runtime, ...)`, +`startLifecycle(ctx, store, zellij.New(...), ...)`, and `zellij.DefaultSocketDir()`. +After the signature change, `startSession` takes `runtimeselect.Runtime`. Update the +test to pass a value that satisfies it. Simplest and most faithful: construct the +real selected runtime via `runtimeselect.New(nil)` (on this Darwin box that yields +the tmux adapter, and tmux is installed), OR pass `tmux.New(tmux.Options{})` +directly. Keep the test's intent. If a sub-test asserts specifically on +`zellij.DefaultSocketDir()` semantics, keep that sub-test pointed at zellij directly +(it is testing the zellij helper, which still exists) — do not delete coverage; just +make it compile and pass. Read the whole test file and adjust only what the signature +change forces. + +## Definition of done (runnable checks — run from `backend/`) +- `go build ./...` succeeds. +- `GOOS=windows go build ./...` succeeds (Windows still compiles on the zellij path). +- `go test ./...` passes (the full backend suite). If any pre-existing test is + flaky/unrelated-failing, note it in the report; do not paper over a failure your + change caused. +- `go vet ./internal/daemon/... ./internal/cli/... ./internal/adapters/runtime/...` + is clean. + +## Hard rules / constraints +- Never use em dashes ("—") anywhere in code, comments, or commit messages. Use + periods, commas, semicolons, or parentheses. +- Do NOT delete the zellij package or change its behavior (Windows depends on it). +- Do NOT change the narrow consumer interfaces or the terminal layer. +- No new Go dependencies. go.mod unchanged. +- Keep changes minimal and on-pattern (ponytail).

TestParserPayloadIsCopy to catch internal-buffer aliasing: feed frame1, capture its payload, feed frame2 of the same length so the parser's buffer overwrites the frame1 region, then assert frame1's bytes are unchanged. The prior test only mutated the input slice post-Feed and did not exercise the real aliasing risk. Add TestRingConcurrent: 10 writer goroutines (Append) and 10 reader goroutines (Snapshot + Tail) running concurrently with a WaitGroup. The test is meaningful only under the race detector and catches any missing mu coverage on Ring's exported methods.

From a7b052b9e1cc743dbef66778e51c9d6521c7074a Mon Sep 17 00:00:00 2001 From: Harshit Singh Bhandari Date: Tue, 23 Jun 2026 23:18:24 +0530 Subject: [PATCH 10/60] feat(conpty): add pty-host serve engine with loopback TCP transport (B3) Ports pty-host.ts behavior to Go: ptyConn interface seam, Serve engine with ring replay, fan-out broadcast, MSG_* handlers, PTY-exit keep-alive, and graceful shutdown (ConPTY dispose first, 50ms grace, then clients and listener). Real conptyConn is Windows-only via build tag; non-Windows stub keeps the package importable on Darwin/Linux. Tests use a fake ptyConn with real loopback sockets and the B1 MessageParser, passing with -race.

Important: in handleConn the ring Snapshot and the client registration ran under two separate h.mu acquisitions. A PTY chunk arriving in that gap was in neither the snapshot nor that client's broadcast, so it was silently dropped (a hole in the client's stream). Now take the snapshot, write it to the conn, and add the conn to the clients set all under a single h.mu hold; broadcast also takes h.mu so it cannot interleave. Added TestScrollbackLiveOrdering_NoDrop, which emits a contiguous numbered stream while a client connects and asserts the client's stream has no internal gap. It reliably fails against the old two-step code and passes under -race -count=20. Minor (faithfulness): conptyConn.Close() now also best-effort Process.Kill() (nil-guarded) so a child that ignores ConPTY EOF still exits and Done() fires, mirroring pty.kill() in pty-host.ts. Minor (simplify): use os.Environ() instead of exec.Command(shellCmd).Environ() for the child env.

Specific concerns: + +1. `go-pty`'s `New()` on Windows returns `ConPty` (confirmed from `pty_windows.go`); the type-assert `p.(gopty.ConPty)` should succeed. If a future go-pty version changes this, the assert will panic at runtime. +2. `cmd.Environ()` on Windows (inside `newConPTY`) calls `exec.Command(shellCmd).Environ()` to inherit the parent environment. This is a lightweight approach but spawns a short-lived process on Windows just to get the env; a cleaner path is `os.Environ()`. Left as-is to match node-pty's `process.env` pass-through semantics. +3. The `conptyConn.Close()` only closes the ConPTY handle (`pty.Close()`), not the cmd process explicitly. On Windows, closing the ConPTY handle causes the child process to receive EOF and exit on its own; this matches how node-pty handles it. If the child does not exit, there is no explicit kill here. + +These are not blocking for Darwin CI; they should be verified in a Windows CI job before merging to production. + +--- + +## Review follow-up (1 Important + 2 Minor fixes) — commit 6cd6e2a + +### 1. Important (real bug): scrollback/live-output ordering could drop bytes +`host.go` `handleConn` took the ring `Snapshot()` and added the conn to the +broadcast set under two separate `h.mu` acquisitions. A PTY chunk arriving in +that gap was in neither the snapshot nor that client's broadcast and was +silently dropped (an internal hole in the client's stream). + +Fix: acquire `h.mu` once, take the snapshot, write it to the conn (only if +non-empty), then add the conn to `clients`, then release. `broadcast()` also +takes `h.mu`, so it cannot interleave: every chunk is either already in the +snapshot or broadcast strictly after the conn joins the set. Added a `ponytail:` +note that the snapshot write happens under the lock (bounded by `MaxOutputLines`; +upgrade path is a per-client send queue). + +Regression test: `TestScrollbackLiveOrdering_NoDrop` (host_test.go). The PTY +emits a contiguous stream of numbered lines (`[NNNN]\n`) while a client connects; +the test asserts the client's received stream has no internal gap in the line +indices and reaches the final chunk. Verified it **reliably fails against the old +two-step code** (reverted temporarily: 9/20 iterations failed with +"non-contiguous line indices (dropped chunk)", e.g. "15 followed by 17") and +**passes under `-race -count=20`** with the fix. + +### 2. Minor (faithfulness): Windows Close() had no Kill fallback +`host_conpty_windows.go` `conptyConn.Close()` now also calls +`c.cmd.Process.Kill()` (nil-guarded) in addition to `pty.Close()`, so a child +that ignores ConPTY EOF still exits and `Done()` fires. Mirrors `pty.kill()` in +pty-host.ts. (windows-tagged; compile-checked via `GOOS=windows go build`.) + +### 3. Minor (simplify): redundant env accessor +`host_conpty_windows.go` now uses `os.Environ()` instead of +`exec.Command(shellCmd).Environ()`; dropped the `os/exec` import, added `os`. + +### Command outputs (run from `backend/`) + +``` +$ go build ./... -> Success +$ GOOS=windows go build ./... -> Success +$ GOOS=linux go build ./... -> Success +$ go vet ./internal/adapters/runtime/conpty/... -> No issues found +$ go test -race -count=20 ./internal/adapters/runtime/conpty/... + 700 passed in 2 packages (35 tests x 20 counts, all green) + +Regression-guard verification (old buggy code reverted): +$ go test -race -run TestScrollbackLiveOrdering_NoDrop -count=20 ... + 11 passed, 9 failed -> "non-contiguous line indices (dropped chunk)" +``` + +Touched only files under `backend/internal/adapters/runtime/conpty/`.

Session resolution uses an in-memory map with B2 registry fallback for daemon-restart recovery. Windows-only detached spawn in spawn_windows.go; stub errors on other OSes. All adapter methods are unit-tested on Darwin against an in-process B3 Serve and fakePTY. 48 tests pass, all three GOOS builds succeed, vet clean.

Production code uses `defaultSpawnHost` (Windows-only real spawn). Tests inject a fake spawner that starts an in-process `Serve` + `fakePTY` on a real `127.0.0.1:0` listener and returns that addr plus a fake PID. This makes all adapter methods testable on Darwin without a real ConPTY. + +**Session resolution:** `Runtime.resolve(id)` checks the in-memory `map[string]*hostSession` first (populated by `Create`). On a cache miss it calls `ptyregistry.List()` and scans for a matching `SessionID`, re-populating the map if found. This gives daemon-restart recovery: a pty-host spawned before a daemon restart is still reachable as long as its registry entry survives and its PID is alive. + +**Registry storage:** The loopback addr (e.g. "127.0.0.1:54321") is stored in `Entry.PipePath` (reusing the existing field whose semantic is "how to reach the host"). The pty-host OS PID is stored in `Entry.PtyHostPID` as specified. + +## Registry-Recovery Path + +`Create` calls `ptyregistry.Register` with the loopback addr in `PipePath` and the pty-host PID in `PtyHostPID`. `Destroy` calls `ptyregistry.Unregister`. `resolve` calls `ptyregistry.List()` (which auto-prunes dead-PID entries) and returns a `hostSession` if found. The `TestResolveViaRegistry` test verifies this: a `Runtime` with an empty in-memory map resolves `IsAlive` and `SendMessage` via the registry entry alone. + +**PID gotcha for tests:** `ptyregistry.List()` prunes entries whose `PtyHostPID` is not alive. Tests that need registry entries to survive the prune use `livePID()` (= `os.Getpid()`, always alive). The `Destroy` test uses `deadPID()` (= 2147483647, MaxInt32, never a real process) so the force-kill step is a safe no-op that does not accidentally kill the test runner. + +## Verification Command Outputs + +``` +go build ./...

A single transient 2s loopback timeout would spuriously kill a live idle session. Now clientIsAlive returns (alive bool, transientErr error): a refused dial is definitively gone (false, nil); a timeout or any connected-then-failed I/O error is transient (false, err) so the reaper records ProbeFailed and retries. Wire IsAlive to propagate it. Add regression test covering both the refused-is-gone and timeout-is-transient paths.

The returned + concrete types must satisfy `ports.Stream` (they already have Read/Write/Close + + Resize). Keep the unix/windows build-tag split (`spawn_unix.go`/`spawn_windows.go`). +- Move pty_unix_test.go / pty_windows_test.go into ptyexec as well (adjust package + + any unexported references). These tests must still pass. +- The terminal package no longer needs defaultSpawn after Step 3; delete the moved + files from terminal. + +## Step 3 — rewire the terminal layer to Attach (`attachment.go`, `manager.go`) +- Replace `PTYSource` with: +```go +// Source is what the terminal needs from the runtime: open an attach Stream and a +// liveness check used to decide whether a dropped Stream should be re-attached or +// treated as a clean exit. +type Source interface { + ports.Attacher + IsAlive(ctx context.Context, handle ports.RuntimeHandle) (bool, error) +} +``` + (Rename PTYSource -> Source throughout terminal, or keep the name PTYSource but + change its methods; pick one and be consistent. Update doc comments that describe + "argv".) +- In `attachment`: delete the `spawn spawnFunc` field and the `spawnFunc` type. + Change the run loop: after the IsAlive gate, do + `rows, cols := a.size(); p, err := a.src.Attach(ctx, a.handle, rows, cols)` + instead of AttachCommand + spawn. `p` is a `ports.Stream`; the rest of the loop + (setPTY/copyOut/clearPTY/Close/reattach/backoff) is UNCHANGED. The local + `ptyProcess` interface in attachment.go can be replaced by `ports.Stream` (same + shape) or kept as an alias; prefer using `ports.Stream` directly. + Keep the failure handling: an Attach error increments failures and backs off (same + as the old spawn error path); a definitive `!alive` still markExited. +- In `manager.go`: delete `spawn spawnFunc`, the `defaultSpawn` default, and + `WithSpawn`. `newAttachment` loses its spawn parameter. `NewManager(src, events, + log, opts...)` keeps `src` (now a `Source`). If tests need to inject a fake, they + inject it via `src` (already the first arg) — so `WithSpawn` is removed and tests + pass a fake `Source` whose `Attach` returns a fake `Stream`. + +## Step 4 — implement Attach on the three adapters +- **tmux** (`internal/adapters/runtime/tmux`): add + `func (r *Runtime) Attach(ctx, handle, rows, cols) (ports.Stream, error)`: + reuse the existing argv builder (the body of AttachCommand: `tmux attach-session + -t `), then `return ptyexec.Spawn(ctx, argv, nil, rows, cols)`. You MAY keep + AttachCommand as an unexported helper that builds the argv, or inline it. Add + `var _ ports.Attacher = (*Runtime)(nil)`. Keep AttachCommand removed from the + public surface only if nothing else uses it (the CLI/doctor do not). +- **zellij** (`internal/adapters/runtime/zellij`): same pattern. zellij's + AttachCommand returns argv AND an env block (Windows ConPTY socket dir); pass both + to `ptyexec.Spawn(ctx, argv, env, rows, cols)`. Add the `var _ ports.Attacher` + assertion. (zellij stays in the tree; Windows still builds it until B6.) +- **conpty** (`internal/adapters/runtime/conpty`): add + `func (r *Runtime) Attach(ctx, handle, rows, cols) (ports.Stream, error)`: + resolve the session addr (the existing resolve()), `dialHost(addr, ...)`, send an + initial MsgResize if rows/cols > 0, and return a `*loopbackStream` that: + - runs a goroutine reading frames via a B1 MessageParser; for each MsgTerminalData + it writes the payload into an internal io.Pipe; `Read` drains that pipe. (The + host sends the scrollback Snapshot as the first MsgTerminalData on connect, so + Read naturally yields the replay first.) + - `Write(p)` sends `EncodeMessage(MsgTerminalInput, p)` to the conn. + - `Resize(rows, cols)` sends `EncodeMessage(MsgResize, json{cols,rows})`. + - `Close()` closes the conn and the pipe; ctx cancellation also closes it. + Add `var _ ports.Attacher = (*Runtime)(nil)`. This is fully testable on Darwin + against an in-process B3 Serve + fakePTY: connect, assert the scrollback replay + arrives on Read, Write reaches the fakePTY input, Resize reaches fakePTY.Resize. + +## Step 5 — update the runtimeselect union (`internal/adapters/runtime/runtimeselect/select.go`) +Replace `AttachCommand(handle) ([]string, []string, error)` in the union `Runtime` +interface with `ports.Attacher` (i.e. `Attach(...)`). Keep the compile-time +assertions for tmux and zellij; they now also assert Attach. The daemon wiring +(terminal.NewManager(runtimeAdapter, ...)) still compiles because the union +satisfies terminal.Source. + +## Step 6 — migrate the terminal tests +- `fakes_test.go`: change `fakeSource` to implement `Attach(ctx, handle, rows, cols) + (ports.Stream, error)` (returning a scripted fake Stream) + IsAlive. Replace + `fakeSpawner`/fake spawn with a fake `Stream` (in-memory Read/Write/Resize/Close, + scriptable like the old fake PTY). Preserve the existing `alive/aliveErr/attachErr` + knobs (attachErr now makes Attach fail). +- `attachment_test.go`, `manager_test.go`, `logger_test.go`, + `attachment_integration_test.go`: update `newAttachment(...)`/`NewManager(...)` + call sites to drop the spawn arg / WithSpawn, and to use the fake Source's Attach. + The integration test (which used the real defaultSpawn + a real runtime) should now + drive a real adapter's Attach (tmux is available; or keep it pointed at whatever + runtime it used, adapted to Attach). Keep every assertion's intent. Do not weaken + tests to pass; if a test asserted argv contents from AttachCommand, re-target it to + assert the adapter's argv via the adapter's own (possibly unexported) builder or + drop only that now-meaningless assertion, noting why. + +## Definition of done (from `backend/`) +- `go build ./...` ; `GOOS=windows go build ./...` ; `GOOS=linux go build ./...` succeed. +- `go test -race ./...` passes (the WHOLE backend suite, not just the changed pkgs). +- `go vet ./...` clean. +- tmux integration test still passes against real tmux 3.6b (the Darwin attach path + must still actually work end to end). + +## Hard rules +- This refactors verified, working code (the tmux attach path shipped in Phase A). + Preserve its behavior exactly; the only structural change is argv->Stream. Do not + alter the reattach/backoff/size/SIGWINCH/detach semantics. +- No new go.mod module. Never use em dashes ("—"). Minimal/idiomatic; mark shortcuts + with `ponytail:`.

From 5bfbc489ccdfdb2fa9caff7471e9a96487d2c8fd Mon Sep 17 00:00:00 2001 From: Harshit Singh Bhandari Date: Wed, 24 Jun 2026 00:25:36 +0530 Subject: [PATCH 16/60] feat(terminal): stream-based Attach for tmux/zellij/conpty Evolve the terminal layer from argv-based attach (PTYSource.AttachCommand + injected spawnFunc) to stream-based attach (Source embedding ports.Attacher). tmux/zellij keep spawning their attach CLI on a local PTY via the new shared ptyexec.Spawn; conpty attaches by dialing its loopback pty-host directly with a loopbackStream over the B1 framing protocol. Reattach/backoff/size/SIGWINCH/detach semantics are unchanged. - ports: add Stream + Attacher. - ptyexec: new shared package holding the creack/pty (unix) and ConPTY (windows) spawn, moved verbatim from terminal with its tests. - terminal: PTYSource -> Source, drop spawnFunc/WithSpawn, run loop calls src.Attach and uses ports.Stream. - tmux/zellij: add Attach (argv via ptyexec.Spawn); conpty: add Attach (loopbackStream); ports.Attacher assertions on all three. - runtimeselect: union embeds ports.Attacher in place of AttachCommand. - tests migrated; new conpty attach_test against in-process Serve+fakePTY.

On app launch, recreate the worktrees, replay the +saved uncommitted work, and restore all sessions. The daemon already starts on +launch and shuts down + frees its port on quit; this plan fills the missing +save/restore middle. + +## Core architectural decisions (settled) + +1. **All save/restore logic lives in the daemon**, not the frontend. The daemon + owns the store, the gitworktree adapter, and the `git` binary. The frontend's + only new responsibility: call the existing `POST /shutdown` endpoint before + it kills the daemon, so the save runs gracefully (SIGTERM remains the + fallback and triggers the same daemon-side save path). +2. **The "last-stop manifest" is the existing SQLite state, not a new file.** + `ListAllSessions` already records id, kind (worker/orchestrator), harness, + `is_terminated`, and `Metadata{branch, workspacePath, agentSessionId, + prompt}`. The `session_worktrees` table already has a `preserved_ref` column + (migration 0009) that nothing currently writes. No manifest.json, no new + migration, no new format. The manifest is a query. +3. **Uncommitted work is captured as a git commit object pointed to by a ref** + `refs/ao/preserved/`. Reject the user's original + `refs/{worktree-path}/uncomit/` naming (worktree paths contain `/`, are not + valid single ref components, and are not stable identity). The session id is + the stable key the rest of the system already uses. +4. **Untracked files: respect `.gitignore`.** Build the preserve commit through + a temp index (`GIT_INDEX_FILE= git add -A; git write-tree; git + commit-tree`) so tracked + staged + new (non-ignored) files are captured, + side-effect-free, without mutating the working tree or the stash stack. + Ignored paths (`node_modules/`, build output, ignored `.env`) are skipped. + Log a one-line count of skipped ignored paths so it is never silent. (Chosen + over `git stash create`, which silently drops all untracked files, and over + `git stash push -u`, which mutates the worktree and the global stash stack.) +5. **Do not weaken the existing dirty-worktree refusal** used by interactive + `ao session kill` / `ao cleanup`. Add a separate `ForceDestroy` that the + shutdown path calls only AFTER the work is captured. Adding `--force` to the + shared remove path would silently destroy work in the interactive flows. + +## Global Constraints (binding — reviewers enforce verbatim) + +- App state resolves under `~/.ao` only (`AO_DATA_DIR`/`AO_RUN_FILE` + overridable).

Branch off `main` + as `feat/session-lifecycle-persistence`. +- The file:line references above are approximate (prefixed `~`). Verify each + with codegraph or grep before editing; the daemon is loopback-only and the + store is sqlc-generated, so confirm signatures rather than assuming. +- Use the `superpowers:subagent-driven-development` skill to execute: fresh + implementer subagent per task, task review (spec + quality) per task, then a + final whole-branch review. Subagents follow TDD. + +## Execution order + +Tasks are sequential where coupled: Task 2 shares the gitworktree adapter with +Task 1 (do 1 then 2, same package); Task 3 depends on 1 + 2; Task 4 depends on +3.

<24b4506@iitb.ac.in> Date: Wed, 24 Jun 2026 05:22:06 +0530 Subject: [PATCH 27/60] feat(workspace): add ForceDestroy for shutdown-path worktree removal Adds ForceDestroy(ctx, info) to ports.Workspace and the gitworktree adapter. It runs `git worktree remove --force`, then prune, then os.RemoveAll as a backstop. A new worktreeForceRemoveArgs builder in commands.go emits --force; the existing worktreeRemoveArgs is untouched so Destroy still refuses dirty worktrees via ErrWorkspaceDirty. TDD: test first creates a dirty worktree, confirms Destroy refuses with ErrWorkspaceDirty, then confirms ForceDestroy succeeds and the path is gone and deregistered. All 1609 backend tests pass.

Never touches the real index or stash stack. Returns empty string for clean worktrees. Logs the count of .gitignore-skipped paths. - ApplyPreserved: replays the preserve commit onto a freshly re-added worktree via "git checkout -- .". Deletes the ref on clean success; keeps it and returns ErrPreservedConflict (wrapped) on content conflicts. - Adds both methods to ports.Workspace interface and stubs them in integration and session_manager test doubles. TDD: wrote two failing tests first (RED confirmed via build failure on undefined methods), then implemented to GREEN. All 39 adapter tests pass.

Replace with git cherry-pick --no-commit which performs a true three-way merge, leaves textual conflict markers on conflict, and exits non-zero so the sentinel is correctly returned. Conflict detection now uses exit code only (locale-independent). Add TestWorkspaceIntegrationApplyPreservedConflict to assert: error is ErrPreservedConflict, preserve ref is kept, conflict markers appear in the file. All 40 tests pass.

Best-effort per session; no kind filter. - RestoreAll: for every terminated session that has a session_worktrees row (the marker written by SaveAndTeardownAll), re-create the worktree, apply any preserved ref (conflict logs and continues), then relaunch via the existing single-session Restore. Sessions killed by the user before shutdown (no row) are skipped. Best-effort per session; no kind filter. - TDD: 9 new tests (RED confirmed via build failure, GREEN confirmed 63 pass). Full suite: 1621 tests across 77 packages.

Create only set `status off`, never `mouse on`, so wheel scrolling silently no-opped. Enable `set-option -t mouse on`, mirroring the existing status-off step. - Link clicking: the default WebLinksAddon handler calls window.open() with an empty URL and then assigns location.href. Electron's setWindowOpenHandler denies every window.open and only forwards the URL passed to it, so the empty open is dropped and clicks no-op. Pass the matched URL to window.open directly so the main process routes it to shell.openExternal (the OS browser).

Pass env to the agent via the exported-vars prefix -+ (do NOT rely on tmux `-e`, which has its own quirks).

Then verify liveness via IsAlive; on failure, Destroy and return an -+ error (mirror zellij's create cleanup discipline). Return -+ `ports.RuntimeHandle{ID: }`. NOTE: tmux needs no pane-id discovery — the -+ handle is just the session id. Keep the handle format simple (the session id); -+ do NOT invent a `session/pane` split unless a consumer requires it (none does — -+ verify). -+- **Destroy**: `tmux kill-session -t `. Treat "session not found"/"can't find -+ session" stderr on a non-zero exit as success (idempotent), mirroring zellij's -+ `deleteSessionMissingOutput`. -+- **IsAlive**: `tmux has-session -t `. Exit 0 => alive. A non-zero exit whose -+ output says the session/server is missing ("can't find session", "no server -+ running", "error connecting") => definitively `false, nil`.

Mark any simplification with a `ponytail:` comment.) -+- **GetOutput**: `tmux capture-pane -t -p -S -` (the `-S -` starts n -+ lines back in history; `-p` prints to stdout). Then apply the ported -+ `trimTrailingBlankLines` + `tailLines(out, lines)`. `lines <= 0` => error, like -+ zellij. -+- **AttachCommand**: return argv `["tmux", "attach-session", "-t", ]` (use the -+ resolved binary path as argv[0]) and a `nil` env block (no per-session socket dir -+ needed for tmux — unlike zellij's Windows ConPTY env).

Keep the handle format simple (the session id); - + do NOT invent a `session/pane` split unless a consumer requires it (none does — - + verify). - +- **Destroy**: `tmux kill-session -t `. Treat "session not found"/"can't find - + session" stderr on a non-zero exit as success (idempotent), mirroring zellij's - + `deleteSessionMissingOutput`. - +- **IsAlive**: `tmux has-session -t `. Exit 0 => alive. A non-zero exit whose - + output says the session/server is missing ("can't find session", "no server - + running", "error connecting") => definitively `false, nil`. Any OTHER error => - + `false, err` (a probe failure, NOT proof of death) — this distinction matters - + because the reaper feeds the lifecycle manager and must not kill a session on a - + transient probe error.

Use - + `tmux send-keys -t -l ` for the literal text (the `-l` flag stops - + tmux interpreting words like "Enter"/"C-c" as key names), chunked via the ported - + `chunks(message, chunkSize)` helper, then `tmux send-keys -t Enter` to - + submit. (Per the agent-orchestrator reference, multiline text can alternatively - + go via `load-buffer -`/`paste-buffer`, but `send-keys -l` chunked is simpler and - + correct — use it. Mark any simplification with a `ponytail:` comment.) - +- **GetOutput**: `tmux capture-pane -t -p -S -` (the `-S -` starts n - + lines back in history; `-p` prints to stdout).

Current behavior matches the task requirements. - ---- - -## Review Fix: Replace checkout with cherry-pick for correct conflict detection - -### Status: DONE (review findings resolved) - -### Problem found in review - -`ApplyPreserved` used `git checkout -- .`, which is a path-checkout (not a merge). Path-checkout unconditionally overwrites the working tree and always exits 0 for content divergence. This made the `if applyErr != nil` conflict-handling block unreachable dead code and left the spec requirement unmet: the `ErrPreservedConflict` sentinel could never be returned. - -### New mechanism: cherry-pick --no-commit - -Replaced with `git cherry-pick --no-commit `. This computes the diff between the preserve commit and its parent (HEAD at save time) and performs a true three-way merge onto the current working tree. On conflict it leaves textual conflict markers (`<<<<<<<` etc.) in the affected files and exits non-zero WITHOUT committing or moving HEAD.

Specific concerns: - -1. `go-pty`'s `New()` on Windows returns `ConPty` (confirmed from `pty_windows.go`); the type-assert `p.(gopty.ConPty)` should succeed. If a future go-pty version changes this, the assert will panic at runtime. -2. `cmd.Environ()` on Windows (inside `newConPTY`) calls `exec.Command(shellCmd).Environ()` to inherit the parent environment. This is a lightweight approach but spawns a short-lived process on Windows just to get the env; a cleaner path is `os.Environ()`. Left as-is to match node-pty's `process.env` pass-through semantics. -3. The `conptyConn.Close()` only closes the ConPTY handle (`pty.Close()`), not the cmd process explicitly. On Windows, closing the ConPTY handle causes the child process to receive EOF and exit on its own; this matches how node-pty handles it. If the child does not exit, there is no explicit kill here. - -These are not blocking for Darwin CI; they should be verified in a Windows CI job before merging to production. - ---- - -## Review follow-up (1 Important + 2 Minor fixes) — commit 6cd6e2a - -### 1. Important (real bug): scrollback/live-output ordering could drop bytes -`host.go` `handleConn` took the ring `Snapshot()` and added the conn to the -broadcast set under two separate `h.mu` acquisitions. A PTY chunk arriving in -that gap was in neither the snapshot nor that client's broadcast and was -silently dropped (an internal hole in the client's stream). - -Fix: acquire `h.mu` once, take the snapshot, write it to the conn (only if -non-empty), then add the conn to `clients`, then release. `broadcast()` also -takes `h.mu`, so it cannot interleave: every chunk is either already in the -snapshot or broadcast strictly after the conn joins the set. Added a `ponytail:` -note that the snapshot write happens under the lock (bounded by `MaxOutputLines`; -upgrade path is a per-client send queue). - -Regression test: `TestScrollbackLiveOrdering_NoDrop` (host_test.go). The PTY -emits a contiguous stream of numbered lines (`[NNNN]\n`) while a client connects; -the test asserts the client's received stream has no internal gap in the line -indices and reaches the final chunk. Verified it **reliably fails against the old -two-step code** (reverted temporarily: 9/20 iterations failed with -"non-contiguous line indices (dropped chunk)", e.g. "15 followed by 17") and -**passes under `-race -count=20`** with the fix. - -### 2. Minor (faithfulness): Windows Close() had no Kill fallback -`host_conpty_windows.go` `conptyConn.Close()` now also calls -`c.cmd.Process.Kill()` (nil-guarded) in addition to `pty.Close()`, so a child -that ignores ConPTY EOF still exits and `Done()` fires. Mirrors `pty.kill()` in -pty-host.ts. (windows-tagged; compile-checked via `GOOS=windows go build`.) - -### 3. Minor (simplify): redundant env accessor -`host_conpty_windows.go` now uses `os.Environ()` instead of -`exec.Command(shellCmd).Environ()`; dropped the `os/exec` import, added `os`. - -### Command outputs (run from `backend/`) - -``` -$ go build ./... -> Success -$ GOOS=windows go build ./... -> Success -$ GOOS=linux go build ./... -> Success -$ go vet ./internal/adapters/runtime/conpty/... -> No issues found -$ go test -race -count=20 ./internal/adapters/runtime/conpty/... - 700 passed in 2 packages (35 tests x 20 counts, all green) - -Regression-guard verification (old buggy code reverted): -$ go test -race -run TestScrollbackLiveOrdering_NoDrop -count=20 ... - 11 passed, 9 failed -> "non-contiguous line indices (dropped chunk)" -``` - -Touched only files under `backend/internal/adapters/runtime/conpty/`.

Production code uses `defaultSpawnHost` (Windows-only real spawn). Tests inject a fake spawner that starts an in-process `Serve` + `fakePTY` on a real `127.0.0.1:0` listener and returns that addr plus a fake PID. This makes all adapter methods testable on Darwin without a real ConPTY. - -**Session resolution:** `Runtime.resolve(id)` checks the in-memory `map[string]*hostSession` first (populated by `Create`). On a cache miss it calls `ptyregistry.List()` and scans for a matching `SessionID`, re-populating the map if found. This gives daemon-restart recovery: a pty-host spawned before a daemon restart is still reachable as long as its registry entry survives and its PID is alive. - -**Registry storage:** The loopback addr (e.g. "127.0.0.1:54321") is stored in `Entry.PipePath` (reusing the existing field whose semantic is "how to reach the host"). The pty-host OS PID is stored in `Entry.PtyHostPID` as specified. - -## Registry-Recovery Path - -`Create` calls `ptyregistry.Register` with the loopback addr in `PipePath` and the pty-host PID in `PtyHostPID`. `Destroy` calls `ptyregistry.Unregister`. `resolve` calls `ptyregistry.List()` (which auto-prunes dead-PID entries) and returns a `hostSession` if found. The `TestResolveViaRegistry` test verifies this: a `Runtime` with an empty in-memory map resolves `IsAlive` and `SendMessage` via the registry entry alone. - -**PID gotcha for tests:** `ptyregistry.List()` prunes entries whose `PtyHostPID` is not alive. Tests that need registry entries to survive the prune use `livePID()` (= `os.Getpid()`, always alive). The `Destroy` test uses `deadPID()` (= 2147483647, MaxInt32, never a real process) so the force-kill step is a safe no-op that does not accidentally kill the test runner. - -## Verification Command Outputs - -``` -go build ./...

Key implementation notes: - -- Uses `golang.org/x/sys/windows.SysProcAttr.CreationFlags = DETACHED_PROCESS | CREATE_NEW_PROCESS_GROUP` and `HideWindow: true`. This mirrors `detached: true, windowsHide: true` from the TS spawn. -- Reads stdout with a `bufio.Scanner` looking for `READY: ` (the format printed by `RunHost` in `host_main.go`). -- On success, calls `stdout.Close()` and `cmd.Process.Release()` to detach the child. `cmd.Process.Release()` is a best-effort detach; the error is intentionally ignored. -- 10s timeout matches the TS source (`10_000` ms). -- The env merge (inherit parent + overlay caller-provided vars) mirrors `{ ...process.env, ...config.environment }` from the TS. - -Concern: `cmd.Process.Release()` on Windows after `cmd.Start()` does not prevent the child from being reaped if our process exits; it only releases the OS handle held by the Go runtime. The child's `DETACHED_PROCESS` flag is what truly detaches it from our console group. This is correct behavior. - -## Interface Compliance - -`var _ ports.Runtime = (*Runtime)(nil)` compiles, confirming `Create`, `Destroy`, and `IsAlive` are all implemented with the correct signatures. `SendMessage` and `GetOutput` are exported but not part of the `ports.Runtime` interface - they are called by the daemon's messenger and output layers directly. `Attach` is intentionally omitted (B5). - ---- - -## Review fix: IsAlive reaper-safety (dead-vs-transient split) - -### The bug -`clientIsAlive` returned a bare `bool`, collapsing dial timeout, read-deadline -expiry, write error, and connection-refused all to `false`. The reaper turns -`(false, nil)` into `ProbeDead`, which the LCM can promote to a permanent -`IsTerminated` reap when the agent has also been quiet >60s. A single transient -2s loopback timeout on a normal idle session would then spuriously kill a live -session. tmux/zellij avoid this by returning a non-nil error for transient -failures (recorded as `ProbeFailed`, ignored and retried). - -### Fix (files touched, all under conpty/) -- `client.go`: `clientIsAlive` now returns `(alive bool, transientErr error)`: - - valid `MSG_STATUS_RES` -> `(true, nil)`. - - dial refused (nothing listening) -> `(false, nil)` definitively gone. - - dial timeout / read-deadline expiry / write error / mid-read EOF / no - STATUS_RES before conn end -> `(false, err)` transient. - - Added `isTimeout` (net.Error.Timeout()) and `isConnRefused` - (errors.Is ECONNREFUSED, plus WSAECONNREFUSED 10061 for older Windows). - "When unsure, prefer transient": any non-timeout, non-refused dial error - returns the error. - - `clientGetOutput` "return empty on failure" behavior left unchanged. -- `runtime.go`: `IsAlive` now propagates `clientIsAlive`'s `(bool, error)` - directly; the unknown-session path still returns `(false, nil)`. -- `runtime_test.go`: - - Updated `TestClientIsAlive_TrueAndFalse` for the new 2-value signature - (refused -> (false, nil)). - - Added regression `TestIsAlive_RefusedIsGone_TimeoutIsTransient`: - (a) resolved-but-refused host -> `(false, nil)`; - (b) resolved host behind a listener that Accepts but never replies, so the - short `isAliveTimeout` read deadline fires -> `(false, non-nil err)`. - -### Command outputs (from backend/) -- `go build ./...` : Success -- `GOOS=windows go build ./...`: Success -- `GOOS=linux go build ./...` : Success -- `go test -race ./internal/adapters/runtime/conpty/...` : 49 passed in 2 packages -- `go vet ./internal/adapters/runtime/conpty/...` : No issues found -- New test verbose: TestIsAlive_RefusedIsGone_TimeoutIsTransient PASS (2.00s) - -### READY-format confirmation (host_main.go, not modified) -`host_main.go:54` prints `fmt.Fprintf(stdout, "READY:%d %d\n", pty.PID(), port)` -i.e. `READY: ` (pid THEN port), which matches spawn_windows.go's -`READY:(\d+) (\d+)` regex.

You MAY keep - AttachCommand as an unexported helper that builds the argv, or inline it. Add - `var _ ports.Attacher = (*Runtime)(nil)`. Keep AttachCommand removed from the - public surface only if nothing else uses it (the CLI/doctor do not). -- **zellij** (`internal/adapters/runtime/zellij`): same pattern. zellij's - AttachCommand returns argv AND an env block (Windows ConPTY socket dir); pass both - to `ptyexec.Spawn(ctx, argv, env, rows, cols)`. Add the `var _ ports.Attacher` - assertion. (zellij stays in the tree; Windows still builds it until B6.) -- **conpty** (`internal/adapters/runtime/conpty`): add - `func (r *Runtime) Attach(ctx, handle, rows, cols) (ports.Stream, error)`: - resolve the session addr (the existing resolve()), `dialHost(addr, ...)`, send an - initial MsgResize if rows/cols > 0, and return a `*loopbackStream` that: - - runs a goroutine reading frames via a B1 MessageParser; for each MsgTerminalData - it writes the payload into an internal io.Pipe; `Read` drains that pipe. (The - host sends the scrollback Snapshot as the first MsgTerminalData on connect, so - Read naturally yields the replay first.) - - `Write(p)` sends `EncodeMessage(MsgTerminalInput, p)` to the conn. - - `Resize(rows, cols)` sends `EncodeMessage(MsgResize, json{cols,rows})`. - - `Close()` closes the conn and the pipe; ctx cancellation also closes it. - Add `var _ ports.Attacher = (*Runtime)(nil)`. This is fully testable on Darwin - against an in-process B3 Serve + fakePTY: connect, assert the scrollback replay - arrives on Read, Write reaches the fakePTY input, Resize reaches fakePTY.Resize. - -## Step 5 — update the runtimeselect union (`internal/adapters/runtime/runtimeselect/select.go`) -Replace `AttachCommand(handle) ([]string, []string, error)` in the union `Runtime` -interface with `ports.Attacher` (i.e. `Attach(...)`). Keep the compile-time -assertions for tmux and zellij; they now also assert Attach. The daemon wiring -(terminal.NewManager(runtimeAdapter, ...)) still compiles because the union -satisfies terminal.Source. - -## Step 6 — migrate the terminal tests -- `fakes_test.go`: change `fakeSource` to implement `Attach(ctx, handle, rows, cols) - (ports.Stream, error)` (returning a scripted fake Stream) + IsAlive. Replace - `fakeSpawner`/fake spawn with a fake `Stream` (in-memory Read/Write/Resize/Close, - scriptable like the old fake PTY). Preserve the existing `alive/aliveErr/attachErr` - knobs (attachErr now makes Attach fail). -- `attachment_test.go`, `manager_test.go`, `logger_test.go`, - `attachment_integration_test.go`: update `newAttachment(...)`/`NewManager(...)` - call sites to drop the spawn arg / WithSpawn, and to use the fake Source's Attach. - The integration test (which used the real defaultSpawn + a real runtime) should now - drive a real adapter's Attach (tmux is available; or keep it pointed at whatever - runtime it used, adapted to Attach). Keep every assertion's intent. Do not weaken - tests to pass; if a test asserted argv contents from AttachCommand, re-target it to - assert the adapter's argv via the adapter's own (possibly unexported) builder or - drop only that now-meaningless assertion, noting why. - -## Definition of done (from `backend/`) -- `go build ./...` ; `GOOS=windows go build ./...` ; `GOOS=linux go build ./...` succeed. -- `go test -race ./...` passes (the WHOLE backend suite, not just the changed pkgs). -- `go vet ./...` clean. -- tmux integration test still passes against real tmux 3.6b (the Darwin attach path - must still actually work end to end). - -## Hard rules -- This refactors verified, working code (the tmux attach path shipped in Phase A). - Preserve its behavior exactly; the only structural change is argv->Stream. Do not - alter the reattach/backoff/size/SIGWINCH/detach semantics. -- No new go.mod module. Never use em dashes ("—"). Minimal/idiomatic; mark shortcuts - with `ponytail:`.

No new backend route, manager method, or OpenAPI regeneration. + +**Tech Stack:** Go backend (session_manager + service/session), React + TypeScript renderer (Radix Dialog, openapi-fetch api client, vitest). + +## Global Constraints + +- No em dashes or en dashes anywhere (prose, comments, commit messages).

Two defects combined: 1. Restore's guard rejected any session with no agentSessionId AND no prompt as ErrNotResumable. But Claude resumes via a deterministic session id regardless of those fields, so promptless orchestrators were perfectly resumable yet always rejected. Workers slipped through only because they carry a prompt. Move the resumability decision to the adapter: restoreArgv returns ErrNotResumable only when GetRestoreCommand reports it cannot resume AND there is no prompt to fresh-launch from. 2. reconcileLive marked a crash-orphaned (dead-runtime) session terminated without a restore marker, so RestoreAll skipped it and it stayed dead. It now saves-and-tears-down to the same end state a graceful shutdown produces (capture work, write the session_worktrees marker, terminate, remove the worktree), so RestoreAll relaunches it on the same boot, resuming history. Crash recovery now matches graceful restart. If work capture fails it terminates without a marker rather than risk losing un-preserved work. Tests: promptless orchestrator restores via adapter resume; promptless session with a non-resuming adapter still returns ErrNotResumable; reconcileLive writes the marker + tears down the worktree. Full backend suite green (1632), gofmt/vet clean.
