* feat(#1680): ADR-1239 Phase C-1 — imperative embedding adapter (composes loadRegistry) [AC2] Phase 3 slice 2 (AC2). The engine-as-library path: createImperativeAdapter composes loadRegistry({includeInstalled:true}) — first-party-wins + consent + fail-closed gates, identical trust semantics to the CLI — and binds the engine surface behind the SAME HostIntegrationInterface the declarative adapter (AC1) satisfies, plus a registry accessor for the composed capability set. - src/adapter-imperative.cts: createImperativeAdapter({runtime}, {loadOptions}) → ImperativeAdapter (kind:'imperative' + .registry + install/uninstall delegating to install-engine). Thin: delegates the loop, does not reimplement. - tests/adapter-imperative.test.cjs: kind (16 runtimes), registry composition (loadRegistry called with includeInstalled:true), loadOptions pass-through, install/uninstall delegation, fail-closed construction. - eslint.config.mjs + docs/INVENTORY-MANIFEST.json: ADR-457 ignores entry + cli_modules entry for the new emitted .cjs (the two drift gates that bit AC1, applied proactively here). Concrete host binding (OpenCode/VS Code/pi) deferred to Phase 5 (#1682). * test: remove dead readStateMd helper from bug-1760 test readStateMd was defined but never called (writeStateMd is the only state-md helper this test uses). Clears the lone no-unused-vars warning so the repo lints fully clean (0 problems). No behavior change — test still passes 2/2. * chore(changeset): add Changed fragment for imperative embedding adapter (#1680) * fix(adapter-imperative): reword comment to avoid injection-scan substring match The prompt-injection scan regex 'act\s+as\s+(?:a|an|the)' was matching the 'act as the' substring inside 'contract as the declarative adapter' (contrACT AS THE). Reword 'contract as' -> 'shape as' — no 'act' substring, identical meaning. Clears the 'lib source files are clean' + 'codebase prompt injection scan' security-gate failures.
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.
