* 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.
