fix(brief): bound crewmate work and add task budgets

[stoneymarrow]

Intent

Add explicit stop conditions and bounded work caps to firstmate's standard ship and scout crewmate brief scaffolds, closing the gap where new obstacles can consume unbounded time without a supervisor-actionable update. Include a default of roughly two hours or 50 significant actions with no supervisor-actionable phase change, while making clear that expected waiting on validation or long test suites is not exhaustion. Add an optional --budget '' task-specific hard cap that renders in the same block. Report early and stop if the task is clearly larger than briefed. Preserve the existing status protocol, isolation assertion, Herdr-lab gate, delivery-mode definitions of done, and shared scaffold structure. Keep the change focused, extend the existing fm-brief tests for ship and scout defaults, the budget override, and unregressed sections, and keep shell scripts shellcheck-clean. Document --budget in AGENTS.md section 11 and docs/scripts.md as an optional per-task control for unattended or long-running task shapes, and fix the fm-brief.sh usage() range so --help includes its entire script contract.

What Changed

• Captain, add standard stop conditions to ship and scout briefs for prolonged work without a phase change and unexpected scope growth, while exempting expected validation waits.
• Add a validated --budget '<text>' hard cap, complete brief help output, and reject missing, unquoted, or secondmate budget arguments.
• Harden transient spawn worktree readiness and locale-safe composer prompt parsing, with regression coverage and fixture updates.

Risk Assessment

✅ Low: Captain, the change is well-bounded, preserves existing brief and delivery-mode invariants, and includes focused validation and regression coverage.

Testing

The successful full-suite baseline was supplemented with the focused fm-brief test and end-to-end CLI generation across ship, scout, direct-PR, local-only, and Herdr-lab modes. Retained Markdown and help artifacts demonstrate the bounded stop behavior and preserved contracts; all checks passed with no worktree residue.

Evidence: Default ship brief

You are a crewmate: an autonomous worker agent managed by firstmate. Work on your own; do not wait for a human.

# Task
{TASK}

# Herdr lifecycle declaration - NOT ENABLED
**HARD SAFETY GATE:** this scaffold cannot inspect the task text that replaces `{TASK}` later.
If the task will start, stop, delete, restart, profile, or otherwise drive Herdr lifecycle behavior, stop and regenerate the brief with `--herdr-lab` before dispatch.
Do not add Herdr lifecycle commands to this unguarded brief by hand.

# Setup
You are in a disposable git worktree of firstmate, at a detached HEAD on a clean default branch.

**Verify isolation before anything else.** Run `pwd -P` and `git rev-parse --show-toplevel`; both must resolve to the disposable task worktree you were launched in, such as a treehouse pool path or an Orca-managed worktree, not the primary checkout firstmate operates from.
The path check is authoritative: `git rev-parse --git-dir` and `git rev-parse --git-common-dir` can help inspect the repo, but they do not prove you are outside the primary checkout.
If the top-level path is the primary checkout or not the worktree you were launched in, STOP - do not branch or commit here - append `blocked: launched in primary checkout, not an isolated worktree` to the status file and stop.

1. First action: create your branch: `git checkout -b fm/evidence-ship`
2. Run `no-mistakes doctor`; if it reports the repo is not initialized here, run `no-mistakes init`.

# Rules
1. Never push to the default branch. Never merge a PR.
2. Stay inside this worktree; modify nothing outside it.
3. Use gh-axi for GitHub operations and chrome-devtools-axi for browser operations.
4. Report status by appending one line:
   `echo "{state}: {one short line}" >> '/var/folders/7t/7s3dd555217fnnjq46z87qvc0000gn/T/no-mistakes-evidence/01KX6TM86Z7W46QDQPQTM395DP/e2e-home/state/evidence-ship.status'`
   States: working, needs-decision, blocked, paused, done, failed.
   Each append wakes firstmate, so report sparingly: only phase changes a supervisor
   would act on (setup done, bug reproduced, fix implemented, validation passed) and the
   needs-decision/blocked/paused/done/failed states. No step-by-step FYI progress lines;
   firstmate reads your pane for that.
   Use `paused: {why}` - distinct from `blocked:` - ONLY when you are deliberately idling on a
   known external wait you expect to clear on its own (an upstream release, a rate-limit reset,
   a scheduled window): firstmate then leaves your idle pane alone and rechecks it on a long
   cadence instead of treating it as a possible wedge. Use `blocked:` when you are stuck and need help.
5. If you hit the same obstacle twice, append `blocked: {why}` and stop; firstmate will help.
6. If a decision belongs to a human (product choices, destructive actions, ask-user findings),
   append `needs-decision: {summary of options}` and stop. Firstmate will reply with the decision.

## Stop conditions
Keep working while the task makes meaningful progress.
Expected waiting on a validation run or long test suite does not count as a no-phase-change stretch.
If roughly two hours or 50 significant actions pass without a supervisor-actionable phase change, append `blocked: budget - {one-line progress + what remains}` and stop.
If the work is clearly larger than this brief, append `blocked: scope - {one-line progress + newly discovered work}` and stop before silently expanding scope.

# Project memory
If `AGENTS.md` or `CLAUDE.md` already exists, or if this task produced durable project-intrinsic knowledge, run `/Users/varun/.no-mistakes/worktrees/62b0bb08545c/01KX6TM86Z7W46QDQPQTM395DP/bin/fm-ensure-agents-md.sh .` in the worktree.
Record only project knowledge useful to almost every future session.
For anything the codebase already shows, prefer a pointer to the authoritative file, command, or doc over copying the detail.
If you touch a project `AGENTS.md` that lacks `## Maintaining this file`, add that short self-governance section from `/Users/varun/.no-mistakes/worktrees/62b0bb08545c/01KX6TM86Z7W46QDQPQTM395DP/bin/fm-ensure-agents-md.sh` in the same pass.
Keep it proportionate: skip `AGENTS.md` edits for trivial tasks that produced no durable project knowledge.

# Definition of done
The task is complete only when committed on your branch.
When you believe it is complete, append `done: {summary}` to the status file and stop.
Firstmate will then instruct you to run /no-mistakes to validate and ship a PR.

You drive no-mistakes by responding to its gates, not by implementing fixes.
Follow the guidance no-mistakes itself provides for the mechanics: it loads when you invoke /no-mistakes, and `no-mistakes axi run --help` plus the `help` lines in each `axi` response are authoritative and version-matched to the installed binary.
Do not hand-edit, commit, or fix findings yourself while a run is active - the pipeline applies every fix.

Two firstmate-specific rules layer on top of that guidance:
- ask-user findings are not yours to answer: escalate to firstmate (rule 6) and stop.
  When the decision comes back, feed it to the gate with `no-mistakes axi respond` and let the pipeline apply it - do not route the question to "the user" or implement the fix yourself.
- Avoid `--yes`: the captain, not you, owns the ask-user decisions it would silently auto-resolve.

After /no-mistakes reports CI green (the CI-ready return point - do not wait for it to keep monitoring in the background until merge), append `done: PR {url} checks green` and stop. You are finished.

Do not add Herdr lifecycle commands to this unguarded brief by hand.

# Setup
You are in a disposable git worktree of firstmate, at a detached HEAD on a clean default branch.
This is a SCOUT task: the deliverable is a written report, not a PR.
The worktree is your laboratory - install, run, edit, and make scratch commits freely; all of it is discarded at teardown.
The report is the only thing that survives, so anything worth keeping must be in it.

# Rules
1. Never push to any remote and never open a PR.
2. Stay inside this worktree; the only files you may write outside it are the report and the status file below.
3. Use gh-axi for GitHub operations and chrome-devtools-axi for browser operations.
4. Report status by appending one line:

If the work is clearly larger than this brief, append `blocked: scope - {one-line progress + newly discovered work}` and stop before silently expanding scope.
Task-specific budget: hard stop at 30 minutes or 20 significant actions
Treat this as a hard cap, and when it is reached append `blocked: budget - {one-line progress + what remains}` and stop.

# Definition of done
Write your findings to `/var/folders/7t/7s3dd555217fnnjq46z87qvc0000gn/T/no-mistakes-evidence/01KX6TM86Z7W46QDQPQTM395DP/e2e-home/data/evidence-scout/report.md`.
The report must stand alone: what you did, what you found, the evidence (commands run, output, file:line references), and what you recommend.
When the report is complete, append `done: {one-line conclusion}` to the status file and stop.
If your findings reveal work that should ship (e.g. you reproduced a bug and the fix is clear), say so in the report; firstmate may promote this task in place, and you would then receive mode-specific ship instructions as a follow-up message.

Evidence: Herdr-lab brief

You are a crewmate: an autonomous worker agent managed by firstmate. Work on your own; do not wait for a human.

# Task
{TASK}

# Herdr isolation - HARD SAFETY CONTRACT
This brief was explicitly scaffolded with `--herdr-lab` because the task will drive Herdr lifecycle behavior.
On Herdr 0.7.3 the API socket is not relocatable by `HERDR_CONFIG_PATH`, `XDG_CONFIG_HOME`, or `HOME`.
A named non-`default` session plus a trailing `--session <name>` on every call is the only viable local isolation.

1. Set `HERDR_LAB_HELPER='/Users/varun/.no-mistakes/worktrees/62b0bb08545c/01KX6TM86Z7W46QDQPQTM395DP/bin/fm-herdr-lab.sh'` and generate the session name with `HERDR_LAB_SESSION=$("$HERDR_LAB_HELPER" name evidence-herdr)`.
   Install `trap '"$HERDR_LAB_HELPER" teardown "$HERDR_LAB_SESSION"' EXIT` before provisioning, then provision only with `"$HERDR_LAB_HELPER" provision "$HERDR_LAB_SESSION"`.
2. Run every task-specific non-lifecycle Herdr command through `"$HERDR_LAB_HELPER" run "$HERDR_LAB_SESSION" <arguments...>`.
   The helper appends the required trailing `--session "$HERDR_LAB_SESSION"`; `HERDR_SESSION` alone is never accepted as isolation.
3. Teardown only through `"$HERDR_LAB_HELPER" teardown "$HERDR_LAB_SESSION"`.
   It re-checks refuse-default immediately before stop and again immediately before delete, and fails closed on ambiguity.
4. If an experiment requires a deliberate mid-run session stop, use only `"$HERDR_LAB_HELPER" stop "$HERDR_LAB_SESSION"`; it performs the same immediate refuse-default check.
5. Forbidden commands: direct `herdr server stop`, every other server-global operation such as `herdr server live-handoff` or reload/update operations, direct `herdr session stop`, direct `herdr session delete`, and any Herdr call scoped only by ambient or inline `HERDR_SESSION`.
6. The helper records the live default session before provisioning and verifies the identical fleet state after teardown.
   A missing, stopped, or changed default session is a hard tripwire failure, never a cleanup warning to ignore.

Never bypass the helper, even for a read-only lifecycle probe or cleanup after failure.
The captain fleet uses the running `default` session.

# Setup
You are in a disposable git worktree of firstmate, at a detached HEAD on a clean default branch.

**Verify isolation before anything else.** Run `pwd -P` and `git rev-parse --show-toplevel`; both must resolve to the disposable task worktree you were launched in, such as a treehouse pool path or an Orca-managed worktree, not the primary checkout firstmate operates from.

Evidence: Complete fm-brief help output

Scaffold a crewmate brief or persistent secondmate charter at
data/<task-id>/brief.md under the active firstmate home.
For ordinary tasks, the standard Setup/Rules/Definition-of-done contract is
filled in. Firstmate then replaces the {TASK} placeholder with the task
description, acceptance criteria, and context, and may adjust other sections
when the task genuinely deviates (e.g. working an existing external PR instead
of shipping a new one).
Usage: fm-brief.sh <task-id> <repo-name> [--scout] [--herdr-lab] [--budget '<text>']
       fm-brief.sh <task-id> --secondmate {<project>...|--no-projects}
  --scout writes the scout contract instead: the deliverable is a report at
  data/<task-id>/report.md (no branch, no push, no PR) and the worktree is scratch.
  --secondmate writes a persistent secondmate charter. The project list
  is cloned into the secondmate home, while the natural-language scope
  tells the main firstmate when to route work there; routine churn stays in its own home;
  captain-relevant escalations and marked from-firstmate replies append to this
  home's status file.
  --no-projects writes a project-less charter for a domain whose subject is the
  firstmate repo itself (its home is a firstmate worktree, its crews take pooled
  worktrees of the same repo). It is mutually exclusive with a project list, and
  omitting both still fails loudly so an accidental omission is never silent.
  Set FM_SECONDMATE_CHARTER='<charter>' to fill the charter text.
  Set FM_SECONDMATE_SCOPE='<scope>' to write a routing scope distinct from the charter text.
  --herdr-lab is mandatory when the task will issue Herdr lifecycle commands.
  It adds the hard isolation contract backed by bin/fm-herdr-lab.sh.
  The flag must be explicit because {TASK} is filled after scaffolding and the
  caller-supplied repo string cannot reliably identify this repo. Briefs made
  without it carry a loud declaration so an omitted contract cannot be silent.
  --budget '<text>' adds a task-specific hard stop to a crewmate ship or scout
  brief's standard stop conditions.
For ship tasks, the definition of done is shaped by the project's delivery mode
(data/projects.md via fm-project-mode.sh; see AGENTS.md project management
and task lifecycle):
  no-mistakes  implement -> /no-mistakes pipeline -> PR -> captain merge (default)
  direct-PR    implement -> push + open PR via gh-axi (no pipeline) -> captain merge
  local-only   implement on branch, stop and report "ready in branch" (no push/PR);
               firstmate reviews, captain approves, firstmate merges to local main
Ship briefs begin with a worktree-isolation assertion before the branch step.
Scout tasks ignore mode - their deliverable is a report, not a merge.
Ship tasks include a project-memory section so durable project-intrinsic
learnings can be committed to AGENTS.md through the project's delivery path;
it carries the AGENTS.md authoring bar (widely useful knowledge only, pointers
over copied detail) and has the crewmate add the fm-ensure-agents-md.sh
self-governance section when a touched project AGENTS.md lacks it.
Refuses to overwrite an existing brief.

✅ No issues found.

🔧 **Review** - 2 issues found → auto-fixed ✅

• ⚠️ bin/backends/herdr.sh:710 - The implementation changes the bare-prompt regex from ^[❯›] to locale-safe ^(❯|›), but docs/configuration.md still recommends the old override. Under byte-oriented locales, that documented override can match unrelated UTF-8 rows and weaken the composer-state injection guard. Update the documented value and explanation.
• ⚠️ bin/fm-brief.sh:98 - Ship/scout parsing ignores extra positional arguments. An unquoted invocation such as --budget hard stop at 30 minutes succeeds but renders only Task-specific budget: hard, silently weakening the intended cap. Reject more than two ship/scout positional arguments so missing quotes fail visibly.

🔧 Fix: Captain, validate brief arguments and document locale-safe Herdr regex
✅ Re-checked - no issues remain.

✅ **Test** - passed
