Two distinct wedges were hit on the same +day (2026-07-27, shannon workspace), and both were recovered by hand using knowledge that lived +only in architect lore: + +**1. Context exhaustion.** `afx spawn --resume` reattaches the *same* conversation — a deep +session resumes deep. The only way to get a builder a fresh window while preserving its working +state is a four-step manual dance: instruct it to write its state to an untracked file, verify +the file, send `/clear` raw, then hand-write a re-orientation message. Two steps in that dance +are silently destructive if they go wrong: + +- **Clearing before the save lands** destroys the builder's working state irrecoverably. The + architect's only defence today is eyeballing the file ("ours was 203 lines"). +- **A re-orientation that omits the role/protocol frame** leaves a builder with a fresh window, + no idea it is a builder, no protocol, and no porch phase — it drifts, and the drift is not + obvious until it has produced off-protocol work. + +**2. Turn-that-never-ends.** A porch-strict builder chained foreground `until [ -f … ]; do sleep 15; done` +loops inside a single turn for 45+ minutes, waiting on a consult verdict file whose producing +process had already died. Because the turn never ended, every `afx send` — including the +architect's unstick order — sat queued and unread. The builder was unreachable by every +documented channel. The recovery that worked was an ESC keystroke into the PTY +(`afx send --raw "$(printf '\x1b')"`), which interrupts the running tool, ends the turn, +and lets the queued messages process. + +Both wedges are systemic, not incidental: the first has no tooling at all, the second has tooling +that had to be *discovered* under pressure rather than reached for, and the behaviour that caused +it (chained foreground waits) is not warned against anywhere a builder can see. + +## Current State + +### Context reset — entirely manual + +There is no reset command. The verified manual sequence is: + +1. Architect messages the builder: write complete working state to an **untracked** file at the + worktree root — role, receipts, open questions, standing orders — written for a cold reader. + (Untracked because `porch done` sweeps staged files.) +2. Architect verifies the file exists and is substantive. +3. Architect sends `/clear` via `afx send --raw`. +4. Architect sends a re-orientation message: role + protocol + worktree/branch, a pointer to the + state file, and anything that post-dates the save. + +Every step is architect-typed, unverified, and reproducible only from memory. + +### What `--resume` actually does (and does not do) + +Relevant because the issue asks reset to "re-inject the porch phase context the same way `--resume` +does", and the real behaviour is narrower than the name suggests: + +- When a resumable prior session is found, `startBuilderSession` launches the harness's resume form + (`claude --resume `) and **skips both the role injection and the initial prompt entirely** — + they are already inside the saved conversation. Nothing is re-injected. +- The full builder prompt (role frame + protocol template + resume notice, assembled by + `buildPromptFromTemplate` and `buildResumeNotice`) is injected only on the *fresh-launch fallback*, + when no resumable session exists. +- So the machinery that produces a correct, complete builder frame exists and is well-tested — it is + just not on the path a reset would take today. + +### Adjacent facts that constrain the design + +- **The role survives `/clear`.** The Claude harness injects the role via `--append-system-prompt`, + a process-level flag. `/clear` clears conversation history, not the system prompt. Only the + initial *user* prompt — the protocol/spec/porch frame — is lost. This materially narrows what + re-orientation must restore, and it is Claude-specific. +- **ESC survives the send path by accident.** `POST /api/send` does `message.trim()` and rejects an + empty result; `\x1b` is not JS whitespace, so it passes through. The verified recovery depends on + that, and nothing currently protects it. +- **`--interrupt` exists but is a different signal.** `afx send --interrupt` writes `\x03` (Ctrl+C) + and bypasses the send buffer. Ctrl+C is a harder signal than ESC and is not what was verified to + unwedge a builder mid-turn. +- **Addressing is already solved.** `resolveTarget` resolves short ids (`1273` → `builder-aspir-1273`) + by tail-match with leading-zero stripping, reports `AMBIGUOUS` on collisions, and is + affinity-aware. Any new command must reuse it rather than re-implement addressing. +- **The registry already holds the frame inputs.** The `builders` table carries worktree, branch, + protocol, issue number, terminal id, type and spawning architect. +- **`.builder-*` is a load-bearing prefix.** `afx cleanup` classifies untracked `.builder-*` files as + scaffold, not dirt, so a worktree carrying them is still considered clean. +- **PTY state is observable.** `GET /api/terminals/:id/output` and `PtySession.lastDataAt` (Spec 467) + allow a command to verify what a builder's terminal actually did, instead of blind-firing. +- **Message delivery is paced.** Messages of ≥4 lines are written line-by-line at 10ms intervals to + dodge paste detection (#584), with a 48KB cap. Large payloads over the message channel are slow + and carry paste-detection risk; the spawn path avoids this by writing a prompt file and having the + launch script `cat` it. + +### Wait discipline — architect lore only + +Nothing in the builder role or any protocol document tells a builder how to wait on an external +artifact. The guidance that would have prevented the second wedge — waits belong in tracked +background tasks that end the turn; verify the producer is alive before waiting; never chain +foreground poll loops — exists today only in the architect's head and in this issue. + +## Desired State + +Three deliverables, sized deliberately differently. + +### 1. `afx reset ` — the designed one + +One command runs the whole sequence with the destructive steps gated on verified evidence: + +``` +afx reset 1273 +afx reset 1273 --note "PR #1280 merged since your last save; rebase before continuing" +afx reset 1273 --dry-run # print the assembled payloads, touch nothing +afx reset 1273 --interrupt-first # builder is wedged mid-turn; ESC before asking for the save +``` + +Sequence: + +1. **Resolve and validate.** Resolve the builder through the same resolver `afx send` uses. Read + worktree, branch, protocol, mode and issue from the registry. Confirm the terminal exists and + is writable. Confirm the harness supports in-session context reset — if it does not, **abort + loudly**; do not improvise an alternative. +2. **Assemble the re-orientation first.** Build the complete re-orientation payload — role frame, + protocol and mode, project/issue, worktree and branch, porch re-entry instruction, the state-file + pointer, and any architect addendum — before anything is sent to the builder. Assembly failure + aborts with the builder untouched. +3. **Request the save.** Send a templated save-state request carrying a fresh nonce, the exact + target path, and a cold-reader content checklist. +4. **Wait for a verified receipt.** Poll the state file until it contains *this run's* nonce, is + substantive, and is size-stable across consecutive polls. Timeout aborts without clearing. +5. **Quiesce.** Confirm the builder's terminal has stopped producing output before typing into it. +6. **Clear.** Send `/clear` raw. +7. **Re-orient.** Deliver the payload assembled in step 2. +8. **Report.** Print what was verified — nonce receipt, state-file size, clear confirmation status, + re-orientation delivery — so the architect can audit the reset rather than trust it. + +### 2. `afx interrupt ` — the small one + +``` +afx interrupt 1273 +afx interrupt 1273 --no-enter +``` + +Writes the verified ESC keystroke into the builder's PTY, bypassing the send buffer. It is the +documented, reachable form of the recovery of record — nothing more. + +### 3. Wait discipline in the builder role + +A short section in the builder role document (skeleton primary, mirrored minimally into `codev/`) +stating the three rules, with the reasoning that makes them stick: + +- A wait is a **claim that a producer exists** — verify the producing process is alive before + waiting on its artifact. +- Waits on external artifacts run as **tracked background tasks that end the turn**; re-invocation + on completion keeps the lane moving *and* keeps the builder addressable. +- **Never chain foreground poll loops.** A turn that never ends makes every `afx send` — including + the order to stop — queue unread. +- If you are wedged anyway, the architect can reach you with `afx interrupt`. + +## Stakeholders + +- **Primary Users**: Architects operating long-running builder lanes (ASPIR/SPIR multi-phase work, + coordinator builders). +- **Secondary Users**: Builders — they receive the save request and the re-orientation, and they are + the audience for the wait-discipline guidance. +- **Technical Team**: Codev maintainers (`area/tower`). +- **Business Owners**: Repository owner (M Waleed Kadous). + +## Success Criteria + +### Functional — `afx reset` (MUST) + +- [ ] `afx reset ` accepts the same address forms `afx send` accepts (full id, short id, + leading-zero variants) and reports the same `NOT_FOUND` / `AMBIGUOUS` errors. +- [ ] **Invariant R1 (assemble-before-destroy)**: `/clear` is never written to a builder's terminal + unless the complete re-orientation payload has already been assembled successfully. Any + assembly failure aborts before the builder is touched at all. +- [ ] **Invariant R2 (fresh-receipt gate)**: `/clear` is never written unless the state file has been + verified to (a) contain *this run's* nonce, (b) meet a minimum-substance threshold, and (c) be + size-stable across consecutive observations. A stale file left by a previous reset MUST NOT + satisfy the gate. +- [ ] **Invariant R3 (complete frame)**: the re-orientation payload always contains role frame, + protocol name and mode, project/issue identity, worktree path, branch name, the state-file + pointer, and — for porch-driven lanes — the porch re-entry instruction. There is no code path + that emits a partial frame; a missing input is an abort, not an omission. +- [ ] Timeout waiting for the state file aborts non-zero, leaves the builder's context intact, and + prints the exact recovery options. +- [ ] `--dry-run` prints both the save request and the assembled re-orientation and writes nothing + to the builder, making R1/R3 auditable by inspection. +- [ ] `--note ` (and/or `--file `) appends architect-supplied content that post-dates the + save to the re-orientation. +- [ ] `--interrupt-first` sends the ESC interrupt before the save request, for a builder already + wedged mid-turn. +- [ ] Artifacts written into the worktree use the `.builder-` prefix so `afx cleanup` continues to + classify the worktree as clean, and they are untracked so `porch done`'s staged-file sweep + cannot pick them up. +- [ ] A harness with no in-session context reset produces a loud, actionable failure — no silent + substitution of a different mechanism. +- [ ] The command reports what it verified at each step; unconfirmed steps are reported as + unconfirmed rather than presented as success. + +### Functional — `afx interrupt` (MUST) + +- [ ] `afx interrupt ` writes ESC to the resolved builder's PTY, bypassing the send buffer + so a mid-turn builder receives it immediately. +- [ ] Byte-for-byte equivalent to the verified recovery `afx send --raw "$(printf '\x1b')"`, + including the trailing Enter (which is what lets already-queued messages process). `--no-enter` + suppresses the Enter. +- [ ] A regression test pins the invariant that the ESC byte survives the send path's `trim()` and + empty-message rejection. + +### Functional — wait discipline (MUST) + +- [ ] The three rules land in the builder role document in the **skeleton** tree as the primary copy. +- [ ] The `codev/` tree receives the same content as a purely additive block — minimal surface, so it + rebases cleanly if spir-1252 removes `codev/` shadow copies. +- [ ] The guidance names `afx interrupt` as the recovery when a builder is wedged anyway. + +### Non-functional + +- [ ] Unit tests cover the reset state machine's ordering invariants (R1, R2, R3) directly — each + invariant has a test that fails if the ordering is inverted. +- [ ] No change to existing `afx send` behaviour. +- [ ] Documentation updated: `codev/resources/commands/agent-farm.md` and the `afx` skill reference, + so the commands are discoverable at the point of use. + +## Constraints + +### Architect directives (fixed — do not relitigate) + +Recorded from the 2026-07-28 architect instruction. The issue carries no `## Baked Decisions` +section; these are the equivalent and are treated as fixed: + +1. Issue body **and** first comment are both in scope. +2. `afx interrupt` is small and must not be over-designed. `afx reset` is where the design effort goes. +3. `afx reset`'s two failure modes must be impossible **by construction**, not merely unlikely. +4. Porch-strict lanes must re-inject phase context the way `--resume` does. +5. Wait-discipline guidance goes in builder-facing role/protocol docs, with the **skeleton tree as + the primary copy** and a minimal `codev/`-side change, to avoid colliding with spir-1252. + +### Technical Constraints + +- **Fail fast, no fallbacks** (repository standing rule). Every unverifiable step aborts loudly + rather than proceeding on an assumption. +- `/clear` is a Claude Code slash command. Reset's in-session mechanism is Claude-harness-specific + and must say so rather than pretend to be harness-agnostic. +- Message delivery is paced (10ms/line above 4 lines) and capped at 48KB, and multi-line writes risk + paste detection. Large re-orientation content should not be pushed through the message channel. +- Never hand-edit `status.yaml`; reset must not touch porch state. It re-orients a builder *toward* + porch (`porch next`), it does not move porch itself. +- Builder addressing must go through the existing resolver — no second addressing implementation. +- Tower must be running; a non-writable terminal is a hard failure (#1198 established that a + silently-dropped write is worse than an error). +- Framework changes must be mirrored across `codev/` and `codev-skeleton/` per repository + convention — subject to directive 5's "skeleton primary, codev minimal" shaping for the docs. + +### Business Constraints + +- Scope is bounded to the three deliverables above. Related prior art (the `/exit` + `spawn --resume` + boundary-recycle pattern, codev#1260's target-by-convention discussion) informs the design but is + not in scope to change. + +## Assumptions + +- Builders reliably obey a direct, well-formed instruction to write a file — this is the same trust + the spawn prompt already depends on, and it was exercised successfully in the manual run. +- `--append-system-prompt` role content survives `/clear` in Claude Code. Reset does not *depend* on + this (R3 requires the frame in the re-orientation regardless), but it is why the compact + re-orientation was sufficient in the manual run. +- `GET /api/terminals/:id/output` is sufficient to observe quiescence and, best-effort, to confirm a + clear. Where confirmation is not possible, reset reports it as unconfirmed. +- The concurrent spir-1252 work may delete `codev/` shadow copies of prompt surfaces; the doc change + is shaped to survive that. + +## Solution Approaches + +The interesting design space is `afx reset`. Three mechanisms were considered for "give the builder +a fresh window without losing its state". + +### Approach A: In-session clear (`/clear`) + assembled re-orientation — **recommended** + +**Description**: Keep the same terminal, PTY and agent process. Gate the clear on a nonce-verified +state-file receipt, assemble the re-orientation before clearing, send `/clear` raw, then deliver a +compact frame message that also points at the full assembled re-orientation written into the +worktree. This automates the verified manual recipe and hardens its two failure points. + +**Pros**: +- It is the **verified** sequence — it worked in production on a real coordinator builder. +- Terminal identity is preserved: dashboard rows, VSCode tabs and shellper attachment all survive, + with no stale-tab churn (#991 territory). +- The role frame survives untouched in the system prompt. +- Scrollback is preserved, so the architect can audit what the builder did before the reset. +- Both failure modes are closable by construction: R2 (nonce receipt) closes clear-before-save; + R1+R3 (assemble first, complete-or-abort) close frame omission. +- No process restart means no window in which the builder is absent from the registry. + +**Cons**: +- `/clear` is Claude-specific; other harnesses must be refused explicitly. +- Re-orientation arrives as a message, so it is subject to pacing/paste-detection limits — mitigated + by keeping the message compact and putting the long form in a worktree file. +- Confirming the clear actually took effect depends on scanning terminal output, which is + version-sensitive; may end up reported as "unconfirmed". + +**Estimated Complexity**: Medium +**Risk Level**: Low + +### Approach B: Session restart (`afx spawn --reset`) + +**Description**: Kill the builder's terminal session and start a new one on the fresh-launch path +(no `--resume`), reusing the entire spawn prompt-assembly and delivery machinery, with the initial +prompt extended by the state-file pointer. + +**Pros**: +- Highest-fidelity re-orientation available: the builder receives a genuine spawn-quality prompt + through the same channel a fresh spawn uses (prompt file `cat`-ed at launch — no pacing limits, + no paste detection). +- Harness-agnostic; needs no in-session clear command. +- R3 is satisfied trivially — it *is* the spawn path. + +**Cons**: +- New terminal id: dashboard rows and VSCode tabs churn, scrollback is lost, and there is a window + where the builder's terminal is gone. +- Heaviest of the three; touches session lifecycle, which is the most incident-prone area of Tower. +- Diverges from the verified recipe, so the "known-good" evidence does not transfer. + +**Estimated Complexity**: High +**Risk Level**: Medium + +### Approach C: In-PTY relaunch (`/exit` + Enter) + +**Description**: Exploit the existing launch loop in `.builder-start.sh`. Rewrite the prompt file +(and, if the builder was previously resumed, the launch script) to carry the reset prompt, send +`/exit`, then send Enter at the loop's "Press Enter to relaunch" pause. The agent relaunches in the +same PTY with a fresh conversation and the freshly written prompt. + +**Pros**: +- Same terminal id *and* spawn-quality prompt delivery — combines A's and B's main advantages. +- Uses machinery that already exists and is exercised on every builder exit. +- Closest to the documented boundary-recycle prior art. + +**Cons**: +- Depends on the exact launch-loop tail text and its `read -r` pause — a brittle coupling to a + bash string, and a missed Enter leaves the builder parked at a prompt doing nothing. +- Requires rewriting `.builder-start.sh` for builders currently on the `--resume` launch form, or + the relaunch silently re-attaches the deep session — the exact failure the feature exists to avoid. +- Multi-step PTY handshake with more states to verify than A. + +**Estimated Complexity**: Medium-High +**Risk Level**: Medium + +### Recommendation + +**Approach A**, with B and C recorded as considered alternatives. A automates a sequence that is +already verified end-to-end, preserves terminal identity, and — critically — the architect's +"impossible by construction" bar is met by *ordering and evidence* (R1/R2/R3), which is orthogonal +to the mechanism. Adopting B or C would trade proven behaviour for prompt-delivery fidelity that A +recovers cheaply by writing the long-form re-orientation to a worktree file. C remains the natural +escalation if message-channel delivery proves unreliable in practice. + +### `afx interrupt` — deliberately one approach + +Per directive 2, no design exploration: a thin command that resolves the builder through the +existing resolver and writes the exact verified byte sequence, bypassing the send buffer. Explicitly +**out of scope**: `--all` broadcast, interrupt-then-message composition (already available via +`afx send --interrupt`), and any escalation ladder (ESC → Ctrl+C → kill). + +## Open Questions + +### Critical (Blocks Progress) +- None. The design is determined by the issue, its comment, and the architect directives. + +### Important (Affects Design) +- [ ] What is the right minimum-substance threshold for the state file? The one verified example was + 203 lines. A byte threshold with a flag override is proposed; the default value should be set + in the plan and justified. +- [ ] Can `/clear` be positively confirmed from terminal output across Claude Code versions, or must + it be reported as best-effort? Decide in the plan; the answer changes only the reporting, never + the ordering. +- [ ] Should the re-orientation's long form live in a worktree file that the builder is instructed to + read, or be inlined into the message? Proposed: compact inline frame (guaranteed to arrive) + **plus** a file pointer for the long form — belt and braces, since the inline frame alone + satisfies R3. + +### Nice-to-Know (Optimization) +- [ ] Should a reset be recorded in the builder registry (e.g. a reset count/timestamp) so the + dashboard can show that a builder has been recycled? Useful signal, not required. +- [ ] Should `afx reset` be reachable from the VSCode builder context menu, as `afx dev` is? + +## Performance Requirements + +- `afx interrupt`: the ESC byte reaches the PTY in well under a second; it must not be subject to + send-buffer deferral under any circumstances. +- `afx reset`: dominated by the builder's own turn latency. The state-file wait needs a generous + default timeout (a busy builder may take minutes to reach the request) and must poll at an + interval that does not hammer the filesystem. No throughput requirements. + +## Security Considerations + +- **No new addressing surface.** Reset and interrupt resolve through the existing resolver, so the + builder→architect spoofing checks and workspace scoping are unchanged. +- **Writing into a builder's PTY is privileged.** Both commands must operate only on builders in the + caller's workspace, exactly as `afx send` does. +- **Path safety.** The state-file path is derived from the registry's worktree, not from user input; + any override must be validated to stay inside the worktree. +- **No secret exfiltration.** The state file stays inside the worktree, is untracked, and is never + transmitted anywhere. `--dry-run` prints only the assembled payloads. +- **Content is builder-authored.** The state file is read only for size/nonce verification — its + contents are never executed or interpolated into a shell command. + +## Test Scenarios + +### Functional Tests + +1. **Happy path**: builder receives the save request, writes a nonce-bearing substantive file; reset + verifies, clears, and delivers a complete re-orientation; report lists every verified step. +2. **Clear-before-save is impossible (R2)**: state file never appears → reset times out, exits + non-zero, and no `/clear` was written to the terminal. +3. **Stale file rejected (R2)**: a substantive state file from a *previous* reset (wrong nonce) is + present at start → reset does not accept it; it waits for the fresh nonce and times out if none + arrives. +4. **Partial file rejected (R2)**: file appears with the nonce but still growing → reset waits for + size stability rather than accepting a truncated save. +5. **Undersized file rejected (R2)**: a nonce-bearing three-line stub does not satisfy the gate. +6. **Frame omission is impossible (R1/R3)**: with a registry input missing (e.g. no protocol + recorded), reset aborts during assembly, before any write to the builder. +7. **Complete frame content (R3)**: assembled re-orientation contains role frame, protocol, mode, + project/issue, worktree, branch, state-file pointer, and — for a porch-strict lane — the porch + re-entry instruction. +8. **Ordering (R1)**: a test that inverts the sequence (clear before assembly) fails, proving the + ordering is enforced rather than incidental. +9. **Addressing parity**: short id, full id and leading-zero forms resolve identically to `afx send`; + an ambiguous short id produces `AMBIGUOUS`. +10. **Unsupported harness**: a non-Claude builder produces a loud abort naming the harness, with no + writes to the terminal. +11. **Non-writable terminal**: reset fails loudly rather than reporting success for dropped writes. +12. **`--dry-run`**: prints both payloads, performs zero writes to the builder and zero worktree + mutations beyond nothing at all. +13. **`--note` / `--file`**: architect addendum appears in the re-orientation. +14. **`--interrupt-first`**: ESC precedes the save request. +15. **`afx interrupt` byte sequence**: writes ESC then Enter, bypasses the send buffer; `--no-enter` + writes ESC alone. +16. **ESC survives the send path**: regression test pinning that a lone `\x1b` message is not + trimmed to empty and not rejected. +17. **Cleanup classification**: a worktree containing reset's artifacts is still reported clean by + `afx cleanup`'s scaffold-only check. + +### Non-Functional Tests + +1. **Docs mirrored**: the wait-discipline section exists in the skeleton builder role and in the + `codev/` copy, with equivalent content. +2. **No regression in `afx send`**: existing send tests pass unchanged. +3. **Discoverability**: the commands appear in `afx --help` and in the agent-farm command reference. + +## Dependencies + +- **External Services**: none. +- **Internal Systems**: Tower (`POST /api/send`, `GET /api/terminals/:id/output`), the message + resolver, the builder registry (`global.db`), the harness abstraction, porch (read-only, for + phase context), `afx cleanup`'s scaffold classification. +- **Libraries/Frameworks**: existing stack only — no new dependencies. + +## References + +- Issue #1273 (body: `afx reset`;

This plan is organised so those invariants are **enforced by +module boundaries, not by discipline**: the reset state machine is a pure, dependency-injected module +whose I/O (clock, filesystem, terminal write, terminal read) arrives as ports, so every invariant can be +tested by inverting the ordering and observing a failure — with no Tower, no PTY and no live builder. + +Phase ordering follows dependency and risk. `afx interrupt` ships **first** because it is small, +independently valuable (it is today's recovery of record, currently reachable only as folklore), and +because reset's R4 escalation reuses its ESC delivery path. Observability (`lastDataAt`) ships second +because R4 cannot be implemented — or honestly tested — without a quiescence signal. The three reset +modules follow, each independently testable, and the orchestrator that composes them lands only once its +parts are proven.

Every required element is read from +an explicit field; a missing field **throws a named error** identifying the field. Completeness is +enforced by construction rather than by review: the required-element list is a constant, and assembly +validates the built payload against it before returning, so adding a required element without producing +it fails the tests. + +**`inline`** (the message, kept compact for the paced channel): reset notice; role frame as an *identity +block* — that the recipient is a builder and which role document governs it, **not** the role's full +text (under the Claude harness the role lives in `--append-system-prompt` and survives `/clear`); +protocol and mode; project id and issue; worktree and branch; `porch next` re-entry for porch-driven +lanes; the `.builder-state.md` pointer with a read-in-full instruction; the addendum. + +**`longForm`** (written to `.builder-reorient.md`): the full assembled re-orientation including any +protocol/phase context too large to inline, plus a pointer back to the state file. + +Both worktree artifacts use the `.builder-` prefix so `afx cleanup`'s scaffold classification +(`cleanup.ts`) continues to treat the worktree as clean, and both are untracked so `porch done`'s +staged-file sweep cannot pick them up. + +**Addendum sources**: `--note ` inline; `--file ` read from the **caller's** filesystem, +exactly as `afx send --file` does (48KB cap reused). The worktree-containment rule applies only to an +override of the *state-file* path, validated in phase 5. + +#### Acceptance Criteria +- [ ] Assembled inline payload contains identity block, protocol, mode, project/issue, worktree, branch, + state-file pointer, and — for a porch-driven lane — the `porch next` instruction. +- [ ] A missing registry field throws a named error rather than emitting a partial frame. +- [ ] The role's full text is **not** inlined. +- [ ] `--note` and `--file` content appears in the payload. +- [ ] Assembly is pure: no terminal writes, no builder contact. + +#### Test Plan +- **Unit**: completeness assertion per element; one test per missing-field abort; a test that adding a + required element without producing it fails; `--file` reads from the caller's filesystem; addendum + placement. +- **Manual**: inspect `--dry-run` output against a live builder record in phase 5. + +#### Rollback Strategy +Delete the module; nothing imports it until phase 5. + +#### Risks +- **Risk**: the inline payload grows past a comfortable paced-write size. + - **Mitigation**: a test asserts an upper bound on inline line count; overflow belongs in `longForm`. + +--- + +### Phase 5: Reset orchestrator + CLI wiring +**Dependencies**: Phases 1, 2, 3, 4 + +#### Objectives +- Compose the verified parts into the `afx reset` state machine, with R1 and R4 enforced by ordering that + is directly testable. + +#### Deliverables +- [ ] `packages/codev/src/agent-farm/commands/reset/index.ts` (new) — the state machine. +- [ ] `packages/codev/src/agent-farm/cli.ts` — register `reset [builder]` with `--note`, `--file`, + `--dry-run`, `--interrupt-first`, `--timeout`, `--min-bytes`, `--quiet-window`. +- [ ] `packages/codev/src/agent-farm/types.ts` — `ResetOptions`. +- [ ] Tests: `packages/codev/src/agent-farm/__tests__/spec-1273-reset-orchestrator.test.ts`. + +#### Implementation Details + +The orchestrator is a pure state machine over injected ports (`clock`, `fs`, `writeToTerminal`, +`readTerminalInfo`, `sendMessage`), so every ordering invariant is testable without Tower, a PTY, or a +live builder. It records an ordered **step log** of every externally-visible action; the invariant tests +assert over that log, which is what makes "impossible by construction" checkable rather than aspirational. + +Sequence: + +1. **Resolve and validate** — reuse `afx send`'s resolver and workspace detection; read the builder record; + confirm the terminal exists and is writable; confirm the harness supports in-session context reset. + A non-Claude harness **aborts loudly**, naming the harness — no substituted mechanism (fail fast). +2. **Assemble (R1)** — build the re-orientation via phase 4 and write `.builder-reorient.md`. Any failure + aborts here, with the builder untouched. **Nothing destructive can precede this step.** +3. **Optional `--interrupt-first`** — for a builder already wedged mid-turn, send ESC via phase 1's path + before the save request. Default off: the default path assumes an addressable builder and does not + guess. +4. **Request the save** — send the phase 3 template. +5. **Await receipt (R2)** — poll until accepted; on timeout abort non-zero, naming the failing gate, with + the builder's context intact. +6. **Quiesce (R4)** — bounded wait for `lastDataAt` to be older than the quiet window; if not reached, + **exactly one** ESC escalation (legal only here, after the R2 receipt); bounded wait again; if still + not quiet, abort non-zero **without clearing**. No third attempt, no "clear anyway". +7. **Clear** — write `/clear` raw. +8. **Confirm (best-effort)** — scan terminal output; an unconfirmed clear is *reported as unconfirmed*, + never as success, and never changes the ordering. +9. **Re-orient** — deliver the inline payload assembled in step 2. +10. **Report** — print each step with its verified evidence: nonce receipt, state-file size, quiescence, + clear-confirmation status, delivery. + +`--dry-run` prints the save request and both payload parts and performs **zero** writes to the builder — +making R1 and R3 auditable by inspection, as the spec requires. + +A state-file path override, if offered, is resolved and validated to remain inside the target builder's +worktree. + +#### Acceptance Criteria +- [ ] Happy path: request → verified receipt → quiescence → clear → complete re-orientation → report. +- [ ] **R1**: no `/clear` in the step log unless assembly succeeded first; a test that inverts the order fails. +- [ ] **R2**: never-appearing, stale-nonce, undersized and still-growing files each abort with **no** + `/clear` in the step log. +- [ ] **R4**: never-quiet terminal → exactly one ESC → abort non-zero, no `/clear`; and the ESC never + precedes the R2 receipt. +- [ ] Unsupported harness and non-writable terminal abort loudly with no terminal writes. +- [ ] `--dry-run` produces zero writes to the builder. +- [ ] `--note` / `--file` reach the payload; `--interrupt-first` places ESC before the save request. +- [ ] Addressing parity with `afx send`. +- [ ] A worktree carrying `.builder-state.md` and `.builder-reorient.md` is still reported clean by + `afx cleanup`'s scaffold check. + +#### Test Plan +- **Unit** (over the step log, ports injected): scenarios 1–14 and 9a/9b/9c from the spec, each asserting + both the outcome and the *absence* of forbidden actions. +- **Integration**: spec scenario 14a — wedged builder → `--interrupt-first` → turn breaks → save request + read → flow completes. Uses the existing terminal test harness; skipped-with-annotation only if the + harness cannot simulate a wedged turn, and called out in the review if so. +- **Manual**: run `afx reset` against a real builder in this workspace and confirm end-to-end behaviour — + "it compiled" is not "it works", and this is the headline user path. + +#### Rollback Strategy +Revert the command and its CLI registration; phases 1–4 remain independently valuable (interrupt ships, +`lastDataAt` is additive, the reset modules are unreferenced). + +#### Risks +- **Risk**: `/clear` cannot be positively confirmed across Claude Code versions. + - **Mitigation**: confirmation is report-only by design; the re-orientation is correct even if the clear + silently failed (worst case: no context saving, no data loss). +- **Risk**: quiescence heuristics misfire on an unusually quiet-but-busy turn. + - **Mitigation**: bounded waits and a single escalation cap the damage at "abort without clearing" — + the safe direction; `--quiet-window` is tunable. +- **Risk**: the manual end-to-end run resets a real builder in this workspace. + - **Mitigation**: exercise `--dry-run` first, then run against a disposable builder, not a live lane. + +--- + +### Phase 6: Wait discipline and command documentation +**Dependencies**: Phase 1 (the guidance names `afx interrupt`) + +#### Objectives +- Move wait discipline out of architect lore into the builder-facing role document. +- Make both commands discoverable at the point of use. + +#### Deliverables +- [ ] `codev-skeleton/roles/builder.md` — **primary copy** of the wait-discipline section. +- [ ] `codev/roles/builder.md` — the same content as a purely additive block. +- [ ] `codev-skeleton/resources/commands/agent-farm.md` and `codev/resources/commands/agent-farm.md` — + `afx reset` and `afx interrupt` reference entries. +- [ ] `.claude/skills/afx` reference updated so the commands are reachable from the skill. + +#### Implementation Details + +The section sits alongside the existing "When You're Blocked" guidance, which today covers only +*architect-blocked* situations and is silent on *external-artifact-blocked* ones. Three rules, each with +the reasoning that makes it stick: + +- A wait is a **claim that a producer exists** — verify the producing process is alive before waiting on + its artifact. (In the incident, the producer had already died, so the wait could never succeed.) +- Waits on external artifacts run as **tracked background tasks that end the turn** — re-invocation on + completion keeps the lane moving *and* keeps the builder addressable. +- **Never chain foreground poll loops.** A turn that never ends makes every `afx send` — including the + order to stop — queue unread. +- Plus the escape hatch: if you are wedged anyway, the architect can reach you with `afx interrupt`. + +**Placement rationale** (architect directive 5): the skeleton is the primary copy; the `codev/` change is +a small additive block. Because `codev/roles/builder.md` shadows the skeleton via the four-tier resolver, +skeleton-only would leave *this* workspace's builders without the guidance — so the mirror is required, +but kept additive so it rebases cleanly if spir-1252 removes `codev/` shadow copies. + +The guidance is scoped to the **builder role** as its single owning surface and deliberately **not** +fanned out into each protocol's prompts — protocol-prompt ownership is spir-1252's subject, and +duplicating guidance across surfaces is what that ownership map exists to prevent. + +#### Acceptance Criteria +- [ ] The three rules and the `afx interrupt` escape hatch appear in both role documents. +- [ ] Command reference documents both commands with their flags in both trees. +- [ ] A repo-wide grep confirms no stale references and that skeleton/`codev` copies agree + (per the standing "grep BOTH trees" lesson). + +#### Test Plan +- **Unit**: a docs test asserting the section exists in both role files with equivalent content. +- **Manual**: read the rendered section as a cold builder would. + +#### Rollback Strategy +Revert the doc commits; no code depends on them. + +#### Risks +- **Risk**: collision with spir-1252's prompt-surface restructuring. + - **Mitigation**: skeleton-primary, additive `codev/` block; check spir-1252's thread before the final + rebase and coordinate via `afx send` if the surfaces have moved. + +## Dependency Map + +``` +Phase 1 (afx interrupt) ─────┐ +Phase 2 (lastDataAt) ────────┤ +Phase 3 (receipt gate) ──────┼──→ Phase 5 (orchestrator + CLI) +Phase 4 (reorient assembly) ─┘ + │ + └──→ Phase 6 (docs, needs Phase 1's command name) +``` + +Phases 1–4 are mutually independent and individually shippable.

charset=UTF-8 Content-Transfer-Encoding: 8bit This phase exists because the plan CMAP caught the first draft assuming the builder registry held these facts. It does not: - builders.protocol_name is NULL for spec-type builders — spawn.ts never passes protocolName on that path, only the protocol-type spawn does. Every SPIR/ASPIR lane, the exact target of this feature, has NULL there. db/schema.ts shows the column and looks fine; the persistence path is where the truth is. - Mode is not persisted at all. resolveMode computes it at spawn from flags plus protocol defaults and discards it, so a spawn-time --soft cannot be recovered by recomputation. - Harness comes from workspace config, which can change while a builder runs. So resolution reads the worktree, which holds all of it authoritatively: status.yaml (protocol, phase), .builder-prompt.txt (the literal '## Mode:' line the builder was given, still correct after --resume), .builder-start.sh (the launch line of the process actually running). Every chain ends in a loud abort, never a default — a guessed protocol or mode yields a plausible re-orientation that quietly reframes the builder, the exact drift R3 prevents. A non-porch lane resolves with porch: null; that is a branch, not a gate failure. Adds supportsContextReset to HarnessProvider (optional, absence means no — the safe direction). Claude declares it; the others abort by name. 24 tests, including resolution succeeding with a NULL protocol_name. --- .../1273-phase_3-iter1-rebuttals.md | 66 ++++ .../__tests__/spec-1273-reset-context.test.ts | 300 ++++++++++++++++++ .../src/agent-farm/commands/reset/context.ts | 285 +++++++++++++++++ .../codev/src/agent-farm/utils/harness.ts | 22 +- 4 files changed, 672 insertions(+), 1 deletion(-) create mode 100644 codev/projects/1273-builder-context-reset-should-b/1273-phase_3-iter1-rebuttals.md create mode 100644 packages/codev/src/agent-farm/__tests__/spec-1273-reset-context.test.ts create mode 100644 packages/codev/src/agent-farm/commands/reset/context.ts diff --git a/codev/projects/1273-builder-context-reset-should-b/1273-phase_3-iter1-rebuttals.md b/codev/projects/1273-builder-context-reset-should-b/1273-phase_3-iter1-rebuttals.md new file mode 100644 index 000000000..847909be9 --- /dev/null +++ b/codev/projects/1273-builder-context-reset-should-b/1273-phase_3-iter1-rebuttals.md @@ -0,0 +1,66 @@ +# Rebuttal — Phase 3 (Reset receipt gate), iteration 1 + +**Verdicts**: Gemini APPROVE (HIGH) · Claude APPROVE (HIGH) · Codex REQUEST_CHANGES (HIGH) + +Both findings accepted, neither disputed. + +--- + +## Codex — REQUEST_CHANGES + +### Issue: "`stateFilePath` is POSIX-only and will generate incorrect paths for Windows worktrees" + +**Accepted.** The helper built the path by hand: + +```ts +return `${worktreePath.replace(/\/+$/, '')}/${fileName}`; +``` + +On Windows that yields `C:\repo\wt\/.builder-state.md` — the trailing-separator strip only matches +forward slashes, and the joiner is a hardcoded `/`.

All accepted; the first defect was found independently by both reviewers. 1. Resolved context was missing specName/specPath/planPath and forwarded rather than resolved the issue number. Phase 5 builds its long form from buildPromptFromTemplate, whose TemplateContext needs those paths; leaving them out would push worktree-reading into the phase whose job is to fail loudly on a missing field, not to go hunting for one. Paths are returned only when the file exists — a pointer to a nonexistent plan would send a freshly-reset builder, with no memory to cross-check against, chasing a ghost. 2. Harness lookup ignored custom providers from .codev/config.json, so a custom-harness builder failed as "no recognisable launch command" — sending the project to debug a config that is correct. Now recognised, mapped via buildCustomHarnessProvider, then capability-checked, so the refusal names the real reason. Custom harnesses stay unsupported by default (the safe default). 3. Harness detection searched the whole line, so a future script containing a conditional that mentions another harness name would return the wrong one. That is not a harmless misread: it either refuses a resettable builder or approves typing /clear into one that cannot reset, where the keystrokes land as literal text in a live agent's prompt. Now matches command position via commandNameOf(), stripping shell keywords and VAR=value prefixes, then basenaming. 4. protocolFromStatus and readPorchContext each scanned the project dirs. Unified — two scans could disagree about which status.yaml is authoritative. 38 tests (was 24). --- .../__tests__/spec-1273-reset-context.test.ts | 150 +++++++++++++++ .../src/agent-farm/commands/reset/context.ts | 172 +++++++++++++++--- 2 files changed, 294 insertions(+), 28 deletions(-) diff --git a/packages/codev/src/agent-farm/__tests__/spec-1273-reset-context.test.ts b/packages/codev/src/agent-farm/__tests__/spec-1273-reset-context.test.ts index 8746488c5..d71250651 100644 --- a/packages/codev/src/agent-farm/__tests__/spec-1273-reset-context.test.ts +++ b/packages/codev/src/agent-farm/__tests__/spec-1273-reset-context.test.ts @@ -284,6 +284,156 @@ describe('resolveBuilderContext (Spec 1273)', () => { expect(() => resolveBuilderContext({ fs: makeFs({}), ...BASE })).toThrow(/Worktree not found/); }); + it('resolves the artifact identity phase 5 needs to rebuild the spawn template context', () => { + const projectDir = '1273-builder-context-reset-should-b'; + const fs = fullWorktree({ + [join(WORKTREE, 'codev', 'specs', `${projectDir}.md`)]: '# spec', + [join(WORKTREE, 'codev', 'plans', `${projectDir}.md`)]: '# plan', + }); + const ctx = resolveBuilderContext({ fs, ...BASE }); + + expect(ctx.specName).toBe(projectDir); + expect(ctx.specPath).toBe(join('codev', 'specs', `${projectDir}.md`)); + expect(ctx.planPath).toBe(join('codev', 'plans', `${projectDir}.md`)); + }); + + it('reports a missing plan as null rather than pointing at a file that is not there', () => { + // A pointer to a nonexistent plan would send a freshly-reset builder — one + // with no memory to cross-check against — chasing a ghost. + const projectDir = '1273-builder-context-reset-should-b'; + const fs = fullWorktree({ + [join(WORKTREE, 'codev', 'specs', `${projectDir}.md`)]: '# spec', + }); + const ctx = resolveBuilderContext({ fs, ...BASE }); + + expect(ctx.specPath).toBe(join('codev', 'specs', `${projectDir}.md`)); + expect(ctx.planPath).toBeNull(); + }); + + it('has no artifact identity on a non-porch lane', () => { + const fs = makeFs({ + [join(WORKTREE, '.builder-prompt.txt')]: BUILDER_PROMPT, + [join(WORKTREE, '.builder-start.sh')]: LAUNCH_SCRIPT, + }); + const ctx = resolveBuilderContext({ fs, ...BASE }); + + expect(ctx.specName).toBeNull(); + expect(ctx.specPath).toBeNull(); + expect(ctx.planPath).toBeNull(); + }); + + it('falls back to the porch project id for the issue number', () => { + // Issue-driven protocols name the porch project after the issue, so this is + // the right value when the registry row carries none. + const ctx = resolveBuilderContext({ fs: fullWorktree(), ...BASE }); + expect(ctx.issueNumber).toBe('1273'); + }); + + it('prefers an explicitly supplied issue number over the project id', () => { + const ctx = resolveBuilderContext({ fs: fullWorktree(), ...BASE, issueNumber: '999' }); + expect(ctx.issueNumber).toBe('999'); + }); +}); + +// ============================================================================ +// Custom harnesses +// ============================================================================ + +describe('custom harness resolution (Spec 1273)', () => { + const custom = { + 'acme-agent': { + command: 'acme-agent', + roleArgs: ['--system', '${ROLE_FILE}'], + roleScriptFragment: "--system '${ROLE_FILE}'", + }, + } as any; + + function customWorktree() { + return fullWorktree({ + [join(WORKTREE, '.builder-start.sh')]: LAUNCH_SCRIPT.replace('claude ', 'acme-agent '), + }); + } + + it('recognises a project-defined harness from the launch script', () => { + expect(harnessFromLaunchScript(customWorktree(), WORKTREE, custom)).toBe('acme-agent'); + }); + + it('maps it to a real provider and refuses on the accurate ground', () => { + // Without custom-harness support the refusal would be "unrecognisable + // launch command", sending the project to debug its config.

charset=UTF-8 Content-Transfer-Encoding: 8bit The failure this prevents is silent. A re-orientation missing its frame does not crash — it produces a builder with a fresh window that does not know it is a builder, what protocol governs it, or what porch expects next, and the drift only surfaces later as off-protocol work. So assembly validates the rendered frame against REQUIRED_INLINE_MARKERS before returning: an element dropped in a refactor fails at assembly rather than reaching a live builder. Two parts with a fixed division: - inline — compact, sent as a message, satisfies R3 on its own. Kept small because the channel writes >=4-line payloads line-by-line at 10ms intervals and multi-line writes risk paste detection (#584). A test pins it under 40 lines and 8KB. - longForm (.builder-reorient.md) — IS the spawn prompt. buildSpawnPrompt is injected and wired in phase 6 to the same buildPromptFromTemplate the fresh-launch path calls, so the builder gets the framing a fresh spawn delivers, through a file rather than a prompt argument. This is the concrete discharge of 're-inject phase context the way --resume does'. The role's full text is deliberately NOT inlined: under the Claude harness it lives in --append-system-prompt, which /clear does not touch, so it survives. R3 is satisfied by the identity block regardless, so the guarantee does not rest on that harness detail. A spawn-prompt render failure aborts rather than degrading — a long form without protocol framing is exactly the partial frame R3 forbids, and it would land on a builder with no context left to notice the gap. 28 tests, including one abort case per required field and a non-porch lane that omits porch re-entry while still satisfying R3. --- .../1273-phase_4-iter1-rebuttals.md | 96 ++++++ .../spec-1273-reset-reorient.test.ts | 297 ++++++++++++++++++ .../src/agent-farm/commands/reset/reorient.ts | 279 ++++++++++++++++ 3 files changed, 672 insertions(+) create mode 100644 codev/projects/1273-builder-context-reset-should-b/1273-phase_4-iter1-rebuttals.md create mode 100644 packages/codev/src/agent-farm/__tests__/spec-1273-reset-reorient.test.ts create mode 100644 packages/codev/src/agent-farm/commands/reset/reorient.ts diff --git a/codev/projects/1273-builder-context-reset-should-b/1273-phase_4-iter1-rebuttals.md b/codev/projects/1273-builder-context-reset-should-b/1273-phase_4-iter1-rebuttals.md new file mode 100644 index 000000000..a7c5641f4 --- /dev/null +++ b/codev/projects/1273-builder-context-reset-should-b/1273-phase_4-iter1-rebuttals.md @@ -0,0 +1,96 @@ +# Rebuttal — Phase 4 (Builder context resolution), iteration 1 + +**Verdicts**: Gemini APPROVE (HIGH) · Claude APPROVE (HIGH) · Codex REQUEST_CHANGES (HIGH) + +All four findings accepted — two blocking from Codex, two non-blocking from Claude.

Double `status.yaml` read + +**Accepted.** `protocolFromStatus` and `readPorchContext` each scanned the project dirs and read the same +file. Claude called it style; I fixed it for a correctness reason it did not mention: two independent +scans could in principle disagree about *which* status.yaml is authoritative if a worktree ever held more +than one project directory. `protocolFromStatus` now delegates to `readPorchContext`, and `protocol` moved +onto `PorchContext`, so there is a single answer by construction. + +### 3. `harnessFromLaunchScript` could false-positive on a conditional + +**Accepted, and this was the most valuable observation of the round.** Claude noted that a future launch +script containing `if [ "$HARNESS" = "codex" ]` would match `codex` by substring and return the wrong +harness. + +That is not a harmless misread. Naming the wrong harness either refuses a builder that *could* be reset, +or — the dangerous direction — approves typing `/clear` into a builder whose harness has no in-session +reset, where the keystrokes land as literal text in a live agent's prompt. + +**Changed** — detection now matches on **command position** rather than searching the line. A new +`commandNameOf()` strips shell control keywords (`while`, `if`, `exec`, …) and leading `VAR=value` +assignments, takes the first token, and basenames it.

All accepted. 1. REQUIRED_INLINE_MARKERS omitted Project:, Issue: and porch next, so those were produced when the context happened to carry them and silently skipped otherwise — the 'optional therefore omittable' shape R3 forbids. The gap was invisible: a porch-driven builder could be re-oriented without its own project identity and nothing would object, leaving it unable to find its spec, plan or status file. Added conditionalInlineMarkers(): required when the lane supplies the fact, so the non-porch case stays honest while omission becomes impossible wherever the fact exists. 2. The plan says the porch re-entry wording reuses buildResumeNotice() verbatim 'so there is exactly one copy of that text'. I restated it instead, which dropped the porch init fallback for when porch reports 'not found' — the recovery a reset builder, with no history to fall back on, would most need. Added a ResumeNoticePort wired in phase 6 to the real buildResumeNotice; the long form embeds its output verbatim. Deviation from the plan's letter: the verbatim reuse sits in the long form, not inline. buildResumeNotice opens 'This is a resumed builder session', which is false after a reset, and it is seven lines in a frame whose fitness for the paced message channel is a tested constraint. The long form preserves what the plan was protecting — one copy, no drift, fallback intact — without telling a freshly-reset builder something untrue about its own state. A porch lane with no notice available now aborts. 3. Tests asserted against the marker list, and the list was the thing that was wrong, so they would have passed with project/issue/porch all absent. A test that validates against the same incomplete constant it polices is not coverage. Now asserts conditional markers directly plus rendered output. 4. Claude (minor): plan assertion checked only path, asymmetric with spec — reusing specName is intentional and deserves pinning. Added resume-notice presence/absence tests. Claude reviewed mid-edit and saw a transient state where the port had become required before the fixture existed; its 20 failures were real when observed and are resolved by the same change. 35 tests (was 28). --- .../spec-1273-reset-reorient.test.ts | 81 ++++++++++++++++++- .../src/agent-farm/commands/reset/reorient.ts | 57 +++++++++++-- 2 files changed, 128 insertions(+), 10 deletions(-) diff --git a/packages/codev/src/agent-farm/__tests__/spec-1273-reset-reorient.test.ts b/packages/codev/src/agent-farm/__tests__/spec-1273-reset-reorient.test.ts index 33e8eacd6..e351f4d2a 100644 --- a/packages/codev/src/agent-farm/__tests__/spec-1273-reset-reorient.test.ts +++ b/packages/codev/src/agent-farm/__tests__/spec-1273-reset-reorient.test.ts @@ -14,6 +14,7 @@ import { describe, it, expect, vi } from 'vitest';

Those were produced when the context +happened to carry them and silently skipped when it did not, which is precisely the "optional, therefore +omittable" shape R3 forbids. + +The gap mattered because it was invisible: a porch-driven builder could be re-oriented without its own +project identity, and nothing in the code or the tests would object. A reset builder that cannot name its +project cannot find its spec, plan or status file. + +**Changed** — added `conditionalInlineMarkers(context)`: markers that are required *when the lane +supplies the corresponding fact*. A porch lane must carry `Project:` and `porch next`; any lane with a +known issue must carry `Issue:`. Validation now checks `[...REQUIRED, ...conditional]`. This keeps the +non-porch case honest — a task builder genuinely has no project — while making omission impossible +wherever the fact exists. + +### Issue 2: "Restates the porch re-entry instruction instead of reusing `buildResumeNotice()` verbatim" + +**Accepted, and this one is mine twice over** — the plan I wrote says "the porch re-entry wording in +`inline` reuses `buildResumeNotice()` **verbatim** rather than restating it, so there is exactly one copy +of that text", and I then wrote my own sentence. + +Codex names the concrete cost: my restatement dropped the `porch init` fallback that `buildResumeNotice` +carries for when porch reports "not found".

It +sits in the long form instead. `buildResumeNotice` opens with "This is a **resumed** builder session", +which is false after a reset — the session was cleared, not resumed — and it is seven lines in a frame +whose fitness for the paced message channel is itself a tested constraint. Putting it in the long form +preserves the property the plan was actually protecting (one copy, no drift, fallback intact) without +telling a freshly-reset builder something untrue about its own state. A porch lane with no notice +available now **aborts**. + +### Issue 3: "Test coverage misses the invariant gap" + +**Accepted.** The suite asserted against the marker list, and the list was the thing that was wrong — so +it would have passed with project, issue and porch re-entry all absent. A test that validates against the +same incomplete constant it is meant to police is not coverage. + +**Changed** — tests now assert the conditional markers directly (porch lane requires `Project:` and +`porch next`; issue-bearing lane requires `Issue:`; non-porch lane requires neither), plus rendered-output +assertions for the project name and issue number, and an abort case for a porch lane with no notice. + +--- + +## Claude — REQUEST_CHANGES + +### Blocking: "20/28 tests fail — helper omits `buildResumeNotice`" + +**Correct as observed, and resolved by the same change.** The `assemble()` helper and three direct +`assembleReorientation` call sites now supply a `resumeNoticePort` fixture that includes the `porch init` +fallback, so the tests exercise the real reuse path rather than a stub that merely satisfies the type. +35 tests pass. + +### Minor 1: "`plan.name` not asserted, asymmetric with `spec`" + +**Accepted.** The plan assertion checked only `path`.

Both points hold the frame to the spec's own wording. 1. The spec requires the identity block to say "that the recipient is a builder AND which role document governs it". The frame said "your role document governs you" — which a builder with no conversation history cannot resolve to a file. Now names `.builder-role.md` (the copy the harness injected at spawn), and that string is in REQUIRED_INLINE_MARKERS so it cannot be dropped. 2. R3 requires project identity; the frame emitted only the directory stem (1273-builder-context-reset-should-b). porch status/porch next take the ID, so a reset builder was left to parse it back out of a slug. Project ID is now stated explicitly in both the inline frame and the long form, and is a required conditional marker on porch lanes. Both gaps were locked in by tests asserting the weaker behaviour — the same pattern as the earlier marker-list problem: the tests kept confirming what the code did rather than what the spec required. 42 tests (was 40). --- .../1273-phase_5-iter2-rebuttals.md | 73 +++++++++++++++++++ .../spec-1273-reset-reorient.test.ts | 21 +++++- .../src/agent-farm/commands/reset/reorient.ts | 23 +++++- 3 files changed, 112 insertions(+), 5 deletions(-) create mode 100644 codev/projects/1273-builder-context-reset-should-b/1273-phase_5-iter2-rebuttals.md diff --git a/codev/projects/1273-builder-context-reset-should-b/1273-phase_5-iter2-rebuttals.md b/codev/projects/1273-builder-context-reset-should-b/1273-phase_5-iter2-rebuttals.md new file mode 100644 index 000000000..7b4c4e266 --- /dev/null +++ b/codev/projects/1273-builder-context-reset-should-b/1273-phase_5-iter2-rebuttals.md @@ -0,0 +1,73 @@ +# Rebuttal — Phase 5 (Re-orientation assembly), iteration 2 + +**Verdicts**: Gemini APPROVE (HIGH) · Claude APPROVE (HIGH) · Codex REQUEST_CHANGES (HIGH) + +Accepted in full.

Structural remedy adopted; the defect claim partially rejected after checking the code. Codex reported that a reset PIR builder gets blank artifact filenames instead of fresh-spawn framing, because PIR's builder-prompt.md consumes {{artifact_name}} and the port never supplies it. Verified: - artifact_name is not on TemplateContext (spawn-roles.ts:25-48). - No spawn path supplies it — all four TemplateContext literals in spawn.ts (:451, :540, :603, :831) omit it; buildPromptFromTemplate adds only protocol_reference. - Only porch supplies it, for per-phase prompts (porch/prompts.ts:102). - renderTemplate renders a missing key as '' (spawn-roles.ts:84-88). So PIR's builder prompt renders that placeholder blank AT SPAWN today. The long form reproduces it exactly, which is what spawn-equivalence means. Reset is matching spawn, blanks included — not degrading it. There is a real bug, but it is PIR's spawn path referencing an unpopulated placeholder, and it predates this work. Fixing it changes another protocol's spawn behaviour, outside a phase contracted to match what spawn delivers. Escalated to the architect rather than silently widened into scope. The suggested remedy is adopted on its own merits: SpawnPromptPort is now typed against the canonical TemplateContext instead of a hand-rolled copy. That local copy is exactly how issue metadata went missing in iteration 2 — a duplicated type drifts and no compiler complains. Now every present and future TemplateContext field is visible here at compile time, which is stronger than the single-field runtime test Codex proposed. 46 tests, build clean.

Accepted in full — two APPROVEs would have shipped a real defect. {{input_description}} is the first content line of bugfix/air/aspir/spir builder-prompt.md, and spawn populates it four different ways: spawn.ts:455 the feature specified in <spec> (spec-driven) spawn.ts:543 an ad-hoc task, plus task_text (--task) spawn.ts:607 running the <PROTOCOL> protocol (protocol-only) spawn.ts:837 work for GitHub Issue #<n> (issue-driven) The reconstruction produced two of the four. A BUGFIX/AIR lane has no spec, so it fell through to the fallback: a reset builder was told it was "running the BUGFIX protocol" instead of naming the issue it is working — on exactly the lanes where the issue body IS the spec. The fallback also read "the <P> protocol" where spawn writes "running the <P> protocol", so even the branch that existed was not spawn-equivalent. Unlike iter 5's artifact_name, this field IS on TemplateContext and IS populated by every spawn path, which is why the finding stands where that one did not. Branch order is load-bearing and not the obvious one: a --task builder gets a porch project keyed on its builder id, so context.ts's `issueNumber ?? porch?.projectId` fallback populates issueNumber for it too. Testing issueNumber before taskText would route every task builder down the issue branch and announce an issue that does not exist. Order is spec -> task -> issue -> protocol-only, documented at the function. Reconstructing the task lane required threading taskText (already persisted as builders.task_text) through ResolvedBuilderContext. Tests 46 -> 51: one per spawn entry point asserting spawn's LITERAL string, plus a task_text negative. The issue-driven case fails against the previous implementation. Iter 5's type-level fix would not have caught this — the field was always present and type-correct, merely wrong; types close the "field missing" class, not the "field wrong" class.

Composes phases 1-5 into the flow the architect ran by hand on 2026-07-27: request save-state -> verify receipt -> wait for the turn to end -> /clear -> re-orient. The orchestrator is a pure state machine over injected ports (clock, fs, sendMessage, sendRaw, sendEscape) and records an ordered step log of every externally-visible action. Reset's safety properties are all ORDERING properties, and a run that clears before saving and one that clears after both end with outcome 'completed' - only the sequence distinguishes them. So the invariant tests assert over the log, and the load-bearing assertions are of ABSENCE: no 'clear' in any aborted run, 'escalate-esc' never before 'receipt-accepted'. R1 assemble + write .builder-reorient.md precede every destructive step; an assembly failure returns with the builder untouched. R2 the poll loop leaves only on 'accepted'; missing / stale-nonce / undersized / still-growing each abort with no clear. R3 delegated to assembleReorientation (throws, never partial). R4 bounded wait -> at most ONE ESC -> bounded wait -> abort. No third attempt, no "clear anyway". lastDataAt === undefined is treated as UNOBSERVABLE, not as quiet: an older Tower omits the field and defaulting it to 0 would read as "silent since 1970" and clear a builder mid-turn. Caught in review, not production: a single writeRaw() port bound to Tower's `escape: true` would have made /clear a no-op. writeEscapeToSession (servers/message-write.ts:46) writes a hardcoded ESC and DISCARDS the message body, so the clear would have sent an interrupt while every signal still read as success - send ok, terminal quiet (ESC ends the turn), re-orientation delivered. The builder would keep its whole context, reported as a clean run. Fixed structurally: three distinct port methods so the confusion is unrepresentable, plus a regression test that /clear goes down the raw channel and escapes === 0. raw:true is also what the manual recipe in the issue used. Also pinned: both artifact names match afx cleanup's /^\?\? \.builder-/ scaffold pattern - a coupling by filename convention, not a shared symbol. 25 orchestrator tests; suite 3899 -> 3926, build clean. CLI verified against the real bin (afx reset --help), not just the build. NOT yet verified end-to-end against a live builder: that needs `pnpm -w run local-install` (restarts Tower, affects every builder in the workspace) and remains the architect's call. --- codev/state/aspir-1273_thread.md | 77 ++- .../spec-1273-reset-orchestrator.test.ts | 581 ++++++++++++++++ packages/codev/src/agent-farm/cli.ts | 36 + .../codev/src/agent-farm/commands/reset.ts | 299 ++++++++ .../src/agent-farm/commands/reset/index.ts | 645 ++++++++++++++++++ packages/codev/src/agent-farm/types.ts | 19 + 6 files changed, 1653 insertions(+), 4 deletions(-) create mode 100644 packages/codev/src/agent-farm/__tests__/spec-1273-reset-orchestrator.test.ts create mode 100644 packages/codev/src/agent-farm/commands/reset.ts create mode 100644 packages/codev/src/agent-farm/commands/reset/index.ts diff --git a/codev/state/aspir-1273_thread.md b/codev/state/aspir-1273_thread.md index 3486e4e04..5f442cca2 100644 --- a/codev/state/aspir-1273_thread.md +++ b/codev/state/aspir-1273_thread.md @@ -193,8 +193,77 @@ unrecorded escalation is indistinguishable from one that never happened.) in PIR spawn prompts), with the recommended fix being to drop the placeholder in favour of porch's per-phase naming.

So `afx send 1273` reached a builder registered as `aspir-1273` and `afx reset 1273` would have failed — in exactly the situation where care is scarcest. Now uses findBuilderById (lib/builder-lookup.ts:48), the resolver afx dev/attach/setup already share: exact lookup, then resolveAgentName locally, then Tower's registry, and AMBIGUOUS reports the candidate list instead of silently picking one. The comment now says what the code does. A docstring asserting an invariant is worse than a missing one: a reader checking "is addressing consistent?" would have read it and moved on. 2. --dry-run printed a blank line under its save-request header — `console.log(result.payload?.longForm ? '' : '')` yields '' on both branches. Root cause was structural: runReset never exposed saveRequest, so the command had nothing to print. saveRequest is now on ResetResult. That text is what the entire R2 gate later verifies compliance with, making it the single most useful thing a dry run can show. 3. No command-surface test caught either — the real finding. Both bugs lived in the wrapper, which the orchestrator's 27 tests cannot see by construction: the state machine cannot tell whether sendRaw was bound to Tower's raw route or its escape route, nor how the builder was looked up. The dangerous part was proven thoroughly; the wiring was left unproven, and that is where both bugs were — and where the earlier /clear-via-escape near-miss was too. New spec-1273-reset-command.test.ts (11 tests): shared-resolver addressing, ambiguous/unresolvable abort before runReset, incomplete registry row refused, /clear on raw and ESC on escape with neither carrying the other's flag, formatted messages carry neither, lastDataAt forwarded as undefined rather than collapsed to 0, non-running terminal reports absent, --timeout seconds->ms conversion, --note/--dry-run/--interrupt-first plumbing, non-zero exit on abort. Plus 2 orchestrator tests: the dry run exposes a request carrying the state path and the nonce, and a live run sends a request byte-identical to the one the dry run advertised (nonce factored out).

Accepted in full. Third time in this project two APPROVEs would have shipped a real defect; second time it was safety-critical. --timeout, --min-bytes and --quiet-window were forwarded from parseInt with no validation. Each bad value does not degrade the run — it switches off a specific protection while the run still reports success: --quiet-window -1 R4 gone. The check is now-lastDataAt >= quietWindowMs, true on the first poll for any negative window, so a builder mid-turn passes quiescence and gets cleared. Phase 2's whole lastDataAt mechanism, defeated by a flag. --min-bytes -1 R2's substance floor gone. bytes < minBytes never holds, so a stub carrying only the nonce is accepted as a save. --timeout nope NaN. Every comparison against NaN is false, so `now >= deadline` never fires and the receipt wait never terminates — a hang, not a wrong timeout. Validated in two places on purpose: 1. cli.ts — positive-integer check per flag, error + exit 1. Verified against the real bin: --quiet-window=-1, --timeout=nope, --min-bytes=0 each print a named error and exit 1. 2. runReset step 0 — every timing/threshold parameter. NOT redundant: the orchestrator owns R2/R4 and must not delegate its own preconditions to its callers; a programmatic caller must not be able to disable an invariant by passing a number.

Accepted — a plan commitment I skipped, not an oversight. The plan's Test Plan required the wedged-builder integration scenario and allowed a skip ONLY if annotated and called out in the review. I did neither: no test, no annotation. Silently dropping the one scenario that models the original incident is the worst of the three available options. The escape hatch turned out to be unnecessary. The wedge is observable to reset in exactly two ways — the builder does not act on messages it has received, and its terminal keeps emitting — and both are expressible against the injected ports, with ESC as the trigger that flips them. I had assumed a harness limitation without checking. Fourth time this phase. Two tests: 1. Recovery. A builder that receives the save request but never reads it, on a terminal that never falls silent. With --interrupt-first the ESC precedes the request, the turn ends, the queued request processes, the state file appears, quiescence is reached, and the flow completes through /clear. 2.

Acceptance criterion "non-writable terminal aborts loudly with no terminal writes" was only half implemented — the harness half, not the writability half. An unwritable terminal passed preflight, .builder-reorient.md was written into the worktree, the save request went into a void, and only then did the run fail. That breaks the validate-before-touch contract. Root cause repeats iteration 3's shape: I checked `status === 'running'` and treated it as evidence of writability. The codebase already knew better — PtySession.writable (pty-session.ts:396) exists precisely because a session whose shellper connection died reports status 'running' while dropping every write (#1198). The getter has been there since #1198 but was NEVER SERIALISED into info, so no client could see it. Capability present, binding absent, and I concluded from the missing binding that the capability was missing. Mirrors what phase 2 did for lastDataAt: - PtySessionInfo gains `writable`; get info() serialises it. - TowerTerminal (core) gains the optional field. - The reset terminal port forwards it as-is, including undefined. - runReset preflight refuses on writable === false, before any write. Deliberate asymmetry, documented at both sites: an unreported lastDataAt REFUSES, an unreported writable PROCEEDS. The rule is not "refuse on unknown" but "refuse what fails silently". An unobservable turn state fails silently and destructively (clear a builder mid-turn); an unobservable write path fails loudly and harmlessly (the send throws). Blocking older Towers entirely would cost reach with no safety return. Tests: preflight aborts with zero file and zero terminal writes; unreported writable still completes; and at PTY level — writable is serialised, agrees with the getter, and reads false while status still says 'running' (the #1198 disagreement, reproduced without contrivance). Codex's second point — scenario 14a is port-level, not PTY-level — is factually right and the plan's escape hatch applies: the terminal harness mocks node-pty and cannot model an agent's TURN, which is what a wedge consists of. A PTY-level "14a" would assert ESC delivery (phase 1 territory) while appearing to cover wedge recovery. Declared explicitly in the rebuttal and carried to the review as a named gap; true end-to-end coverage is the live run scheduled for the post-merge verify window.

Accepted. awaitQuiescence tested `lastDataAt === undefined` without first testing `exists`. A terminal that vanishes mid-run — builder exited, Tower restarted, session killed — also reports no lastDataAt, so it took the 'unobservable' branch and told the architect their Tower was too old and to restart it on a current build. Confidently wrong: they go check a version number while their builder's terminal is gone. A diagnosis bug, not a safety bug, and worth naming the difference. The invariants held — both paths abort, neither clears. What failed is the thing the report exists for. The whole argument for the step log and evidence- carrying aborts is that the safe outcome is not sufficient; the operator has to know what happened. Same family as the clear-unconfirmed finding: output that looks like knowledge and is not. `exists` is now checked first, in both the poll loop and the post-deadline re-check, with its own 'terminal-gone' reason and message pointing at the saved state and `afx spawn --resume`. That recovery is the point: the state file was verified BEFORE quiescence began, so this is the one abort where the architect holds a complete nonce-verified save and no session to apply it to.

Moves wait discipline out of architect lore into the builder-facing role document, and makes both commands discoverable where they are looked up. Role doc (skeleton primary, codev mirror kept byte-identical — the four-tier resolver means codev/ SHADOWS the skeleton for this workspace, so skeleton-only would leave our own builders without the guidance and codev-only would leave every adopter without it). Three rules, each with the reasoning that makes it stick: - A wait is a CLAIM THAT A PRODUCER EXISTS. Verify the producing process is alive first. In the incident (2026-07-27) the producer had already died, so the wait was not slow — it was unsatisfiable. - Run waits as tracked background tasks that END THE TURN. A turn that ends is a turn someone can interrupt. - NEVER CHAIN FOREGROUND POLL LOOPS. Not for efficiency: every afx send — including the order to stop, including a reset request — queues unread until the turn ends. A turn that never ends is a builder nobody can reach, and from inside the turn everything looks fine. - Plus the escape hatch: afx interrupt and afx reset both reach you anyway, worth knowing so you can suggest them when you notice trouble. Command reference: full afx reset and afx interrupt entries in BOTH trees, including every flag and the fail-safe property (every gate aborts without clearing). That last part is load-bearing for adoption — without it the command reads as far more dangerous than it is and goes unused. Both skill trees updated: .claude/skills/afx/SKILL.md AND .codex/skills/afx/SKILL.md. Updating only the Claude one would leave Codex-driven agents with no reason to believe reset exists. 18 docs tests: the three rules and their reasoning are present in both role docs, all eight reset flags are documented in both command docs, the fail-safe property is stated, both skill trees carry both commands, and the role-doc and skill-doc pairs are asserted byte-identical. Docs tests are usually a smell; they earn their place because four parallel trees is exactly where "updated one, forgot the twin" hides — it is invisible in review since the file you are reading looks right. This is the standing "grep BOTH trees" lesson, executed. Noted, not fixed: codev/ and codev-skeleton/ copies of agent-farm.md carry ~375 lines of PRE-EXISTING drift unrelated to this work (wording of shellper descriptions etc). My added sections are byte-identical across both; the existing drift is out of scope and left for a reconciliation pass.

The ground truth is in the + worktree: porch `status.yaml` (protocol, phase), `.builder-prompt.txt` (`## Mode: STRICT`), + `.builder-start.sh` (the real harness launch line). +- **The role frame survives `/clear`.** Roles are injected via `--append-system-prompt`, a process flag. + Only the initial *user* prompt (protocol/spec/porch framing) is lost, which is what re-orientation must + restore — not the role text. +- **`--resume` re-injects nothing** when a resumable session is found; the builder prompt is only built on + the fresh-launch path. "Re-inject context the way `--resume` does" therefore means reusing + `buildPromptFromTemplate` + `buildResumeNotice`, the *fresh-path* machinery. +- **`GET /api/terminals/:id/output` existed with no client binding** until this spec added + `TowerClient.getTerminalOutput`. Worth remembering as a class: a missing binding makes an existing + capability invisible. + +## Lessons Learned + +**A majority APPROVE is not consensus.** Across this project, **four times** two reviewers approved code +that contained a real defect, and each time the single dissenter was correct on the facts. Phase 5's +`input_description` covered half of spawn's entry points; phase 6 shipped addressing that contradicted its +own docstring, a blank `--dry-run` output, CLI flags that silently disabled R2/R4, and a confirmation step +that could only pass in tests. Decide on the argument, not the count — and a reviewer who dissents every +round may be tracking a *defect class* rather than nitpicking. + +**Test the boring wiring, not just the dangerous logic.** The orchestrator — the part that got the careful +design, the step log, the ordering proofs — was essentially right from the first iteration. *Every* phase-6 +defect was in the thin wrapper. A pure state machine over injected ports is structurally blind to how those +ports are bound: it cannot see whether `sendRaw` went to Tower's `raw` or `escape` route, whether the +builder was resolved by exact id or the shared resolver, or whether an optional port method exists in +production at all. The separate command-surface test file added mid-phase caught four regressions. + +**Beware steps that report as attempted but can only succeed in tests.** Two defects had this exact shape: +`/clear` bound to the escape route (reports a clean run; builder keeps its context) and `readRecentOutput` +left unbound (reports `clear-unconfirmed` forever, having never looked). Both had passing tests, because +the mocks supplied what production did not. When a check can only pass under test, it is worse than absent +— it manufactures false confidence. + +**Types close the "field is missing" class, not the "field is wrong" class.** Phase 5's structural fix — +typing the port against the canonical `TemplateContext` — was correct and would not have caught the very +next defect, because `input_description` was always present and always type-correct, merely wrong. Values +that must match another module's literal output need tests pinned to those literals. + +**A docstring asserting an invariant is not evidence of it.** I wrote "addressing is reused verbatim from +`afx send`" and then used an exact-match lookup. That is worse than the gap: a later reader auditing +addressing consistency would have read the comment and moved on. When a comment says "this reuses X", +open X. + +**Distinguish "refuse on unknown" from "refuse what fails silently".** Reset treats an unreported +`lastDataAt` as a refusal but an unreported `writable` as fine. That looks inconsistent and is deliberate: +an unobservable turn state fails silently *and destructively*; an unobservable write path fails loudly and +harmlessly. Conservatism should be spent where failure is quiet. + +**An abort that names the wrong cause is a bug even when the invariant held.** A vanished terminal was +reported as "your Tower is too old" — safe, but it sends the operator to check a version number while +their builder is gone. If the argument for a design is that the operator gets evidence, wrong evidence is +a defect. + +**Process (strict mode):** take the consultation task from `porch next` and run *that*. I ran consults +directly for six rounds; porch never registered them and its counter drifted five iterations behind. The +files were genuine so the history reconstructed cleanly, but porch does not watch what it did not ask for. + +## Deviations from the plan + +- **Phase 5's `buildResumeNotice` reuse moved from `inline` to `longForm`.** The plan said the verbatim + reuse would sit inline. `buildResumeNotice` opens with "This is a **resumed** builder session", which is + false after a reset, and is seven lines in a frame whose paced-write size is a tested constraint. The + long form preserves the property the plan was protecting — one copy, no drift, `porch init` fallback + intact — without telling a freshly-reset builder something untrue about itself. +- **`taskText` was threaded through `ResolvedBuilderContext`** (a phase-4 type) during phase 6's + `input_description` fix, because the ad-hoc-task spawn lane is otherwise indistinguishable from the + issue-driven one. +- **Phase 4 deliberately did *not* add a `mode` column to the builders table.** It would be NULL for every + currently-running builder, so the worktree derivation is required regardless, and the column would + duplicate a fact the worktree already holds.

Third consecutive finding on the same three lines, third distinct false-report mechanism. buildSaveRequest opens with "CONTEXT RESET INCOMING — save your working state now.", which matches /context (?:cleared|reset)/i.

Last round I removed the `/clear` alternative without asking the obvious follow-up: what else in this buffer did I put there?

The defect was scanning a buffer that CONTAINS reset's own writes and hoping the pattern would not collide. Reset writes into that terminal three times per run; collision is the default, not a risk. Fixed structurally: readRecentOutput becomes readOutput(): { lines, total }. The orchestrator snapshots `total` immediately before sending /clear and confirms against only the lines produced after it. Everything reset wrote sits at or below the snapshot and is excluded by construction, so a future pattern change cannot reintroduce the class. Test harness models it honestly — PRE_CLEAR_BUFFER carries the real save-request header, so a windowing regression leaks reset's own words into the check and fails the negatives. Two tests pin the closed cases (echoed /clear, echoed save request), one confirms the check still fires on genuine post-clear output (a guard that only ever returns false is no better than the unbound version). Named in the review as a remaining gap: the PATTERN is still unvalidated. I have never observed what a real /clear emits, so the matched strings remain an educated guess. The window closes the false-positive class; it cannot prove the pattern ever matches in production. clear-confirmed means "the harness said something clear-like", never proof.
