* test(#2686): failing-first parity guard for Workflow-backend model threading The Workflow backend emitted every agent() call with no model, so model_overrides / model_policy / model_profile were silently inert on that path while the inline path honored them (ADR-1411). Neither existing suite contained the string 'model' at all. The centrepiece derives BOTH sides from resolveModelInternal(cwd,'gsd-executor') rather than hardcoding either, so it asserts backend parity rather than a fixed string. Also covers: omit-on-inherit/empty (#2517), byte-identical output when nothing resolves, the #2772/#2285 per-plan worktree gate, adversarial model ids reaching the code generator, the #2285 composed seam, CLI config-defaulting, and a fast-check round-trip property. RED expected: no model key is emitted anywhere, and --executor-model does not exist.

The model was not dropped at the last step — it was absent from the whole seam: agentOptions() took no model, EmitInput had no field to carry one, and ResolveWaveDispatchInput (the #2285 seam the orchestrator actually calls) could not forward one. The generated script asserted the parity it broke. VERIFY-FIRST, which #2686 flags as the question that decides the fix: the Workflow tool's agent() DOES accept a per-call model. Its documented signature is agent(prompt, opts?: { label?, phase?, schema?, model?, effort?, isolation?, agentType? }) so fix branch 1 applies and branch 2 (declare model routing unavailable) is ruled out. ADR-1143:24's option enumeration omitting `model` is an incomplete enumeration, not a decision to exclude it. - agentOptions(p, executorModel) emits `model` only when it is a non-empty string that is not "inherit" (#2517: an empty model 404s on runtimes without native tier aliases). A non-string is a malformed config: omit, never throw. - executorModel threaded through EmitInput and ResolveWaveDispatchInput. - The CLI resolves gsd-executor from project config by DEFAULT rather than requiring a flag, reading the same source the inline path reads. An orchestrator that never learns about a new flag would otherwise silently keep the old bug. --executor-model exists only to pin/override. - ADR-1411 provenance: the generated header now states which model was applied, or that none resolved and why. A fallback must be a visible value. Compatibility: when nothing resolves, the emitted options object is byte-identical to before, so every existing caller and assertion is unaffected. Behavior change (Hyrum's Law): opted-in users move from session inheritance to the catalog-resolved executor model. Adding a `model` key also changes agent() opts, which invalidates the cached prefix of any in-flight resumeFromRunId run — a one-time re-execution. Both disclosed in the changeset. Fixes #2686 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01DPq9ovaovP2UvSVLjD4Lso * fix(#2686): reject script-breaking model ids and share the emit predicate The isolated adversarial review found a BLOCKER in my own provenance comment, proven by execution (the emitted script exited 42 from an injected statement). U+2028/U+2029 are ECMAScript LineTerminators that END a `//` single-line comment in EVERY engine — the ES2019 change legalized them inside string LITERALS only. So quoteString (JSON.stringify) is sufficient for the `model: "..."` object literal but NOT for the `// model: ...` provenance line I added: a raw U+2028 in a model id closed the comment and made the rest of the line live top-level code. The value is reachable from `.planning/config.json` (model_overrides / model_policy), which `mapClaudeOverrideForRuntime` passes through verbatim on any non-claude runtime — attacker-influenceable in a cloned repo. `emitWorkflowScript` now rejects a string executorModel carrying any character in UNSCRIPTABLE_CHAR_RE — the same class `isScriptableIdentifier` already applied to phaseDir/runId, which is proof the codebase knew this hazard. Rejection is ok:false with a reason rather than a silent drop, and resolveWaveDispatch maps an emit failure to the inline backend WITH that reason, so the degradation is visible. A non-string stays on the existing defensive path (omit, never throw) — that is malformed config, not an injection attempt. Also from the reviews: - The predicate deciding "is this model emittable" was duplicated between the emission and the comment asserting it. Extracted to emittableModel() so a generated comment can never claim something the generator did not do — the exact failure class #2686 was filed for. - That predicate now trims and lower-cases before comparing, closing a real #2517-class gap: " " and "INHERIT" were previously emitted verbatim. - The adversarial test was pass-always against this very vulnerability — it asserted only that JSON.stringify appeared. Replaced with the real contract (rejection) plus an execution-level check that no LineTerminator survives into the comment. A raw U+2028 had also been committed into that test's fixture array where a tab was intended; both are now explicit \u escapes. - optionsOf in the test was /\{[^}]*\}/, which truncated at any brace a generated model contained — silently not testing what it claimed. Now brace- and string-aware. Stale-test corrections in tests/fix-2285-*: three assertions froze the exact options literal `{ agentType: "gsd-executor" }`. The object legitimately gained an optional additive `model` key, so they now assert the invariant they exist to protect (agentType present, isolation absent) rather than a frozen literal. The CLI-vs-pure equality test pins --executor-model on both sides; otherwise it compared a config-resolved CLI run against a pure call given no model. CONTEXT.md glossary updated for the changed emitWorkflowScript signature and the new rejection rule (CLAUDE.md: the glossary is a PR gate for core-module changes). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01DPq9ovaovP2UvSVLjD4Lso * test(#2686): fix the options extractor and model the rejection path Two defects in my own test helper, caught by the full matrix: - optionsOf anchored on /\(\s*\{/ — a '(' immediately followed by '{'. The emitted shape is agent("brief", { ... }), so that never matched and the helper returned an empty array, making every assertion over it vacuously true. It now anchors on agent( and takes the first balanced, string-aware {...} after it. - The fast-check property predated the security fix and asserted ok:true for any generated string. Strings carrying an unscriptable character are now rejected, so the property models the real three-way contract: unscriptable -> ok:false; trims to empty or 'inherit' (any case) -> omitted; otherwise -> emitted as the trimmed value. Verified locally against the built module: omit values clean, both plans carry the model on the parity path, property passes 500 runs at seed 42. Test file re-scanned for raw hazardous codepoints — zero; the U+2028/U+2029 cases are explicit \u escapes.

UNSCRIPTABLE_CHAR_RE is not exported from src/claude-orchestration.cts, hence the mirror.

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

**`/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.
