Tom Boucher 91bd82f9a6 enhance(execute): isolated-executor rejected/over-reaching run fails safe — never default recovery to main (#1292) (#1303)
* enhance(execute): isolated-executor rejected/over-reaching run fails safe (#1292)

When an isolated (worktree) executor run is rejected — the user declines to
merge it, the orchestrator surfaces recovery for a blocked/halted plan, or the
run over-reached the requested scope — the orchestrator must no longer
default/propose recovery by editing the primary checkout (`main`). Absent an
explicit guardrail, the LLM orchestrator could improvise "continue on main",
inverting the isolation contract at the moment it matters most.

Added an ISOLATED-RUN RECOVERY — FAIL SAFE policy: default to a safe halt that
offers a fresh, narrowly-scoped worktree or inspect/discard; editing the primary
checkout requires explicit, clearly-labeled confirmation and is never the
default/proposed option.

To respect the ADR-857 phase-6 host-loop size cap on execute-phase.md (it sits
just under the pre-phase-6 baseline), the policy is delivered as an extracted
reference fragment rather than inline:
- New `execute-phase/steps/worktree-recovery-policy.md` holds the recovery policy
  (the existing FAIL-CLOSED rule #48 for base/HEAD mismatches + the #1292
  fail-safe guardrail). No #48 behavior change — moved verbatim.
- execute-phase.md references the fragment at the worktree-spawn recovery point,
  the step-5.5 merge decision, and the stalled-agent "switch to inline execution"
  menu (which for an isolated run now follows the fail-safe policy). Net effect:
  execute-phase.md shrinks below its cap.
- quick.md carries the fail-safe guardrail inline at its post-return merge/discard
  decision (quick.md is not size-capped).

Scoped to the recovery offer only — no automatic scope-overreach detection
(explicitly out of scope per the issue) and no new config key. Adds content
regression tests, a USER-GUIDE note, and a workflow size-baseline update.

Changeset Fragments

This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.

Why

Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.

See #2975 for the full rationale.

Adding a fragment

node scripts/changeset/new.cjs \
  --type Fixed \
  --pr 1234 \
  --body "fix the thing — explain the user-visible change in one sentence"

This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.

Format

---
type: Fixed
pr: 1234
---
**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.

Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.

Opting out

PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.

At release time

Promotion is automatic. The release workflow's finalize job runs:

node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD --allow-empty

This reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, and deletes consumed fragments. The --allow-empty flag ensures a no-change release still gets a dated heading (with a _No notable changes._ placeholder). A subsequent verify step confirms the promotion landed correctly. Maintainers do not run this by hand.

Archived fragments

.changeset/archived/ holds fragments for already-shipped releases (≤ 1.3.1), retained for provenance. Their content was hand-curated into the dated ## [1.x.y] sections of CHANGELOG.md during the #690 backfill — they were never consumed by render. All changeset tooling enumerates .changeset/ non-recursively, so archived fragments are never picked up or rendered. Do not move them back to the top level.
