test(js): enforce full configured coverage

[seonghobae]

Summary

• raise the configured desktop and @bandscope/shared-types Vitest coverage thresholds to 100% for lines, functions, branches, and statements
• add a regression guard that fails when the shared-types package reintroduces a lower owned JavaScript coverage floor
• document the repository-wide configured Vitest coverage contract without changing the production denominator or excluding additional source

Exact current identity

• Protected target: develop@889d782e88b4df28dcbb4ae3cfd6d99ef85d9844.
• Branch: codex/js-coverage-gate.
• Exact current head: 47ef7945fa9df371d5226b5f8e872315249902bd.
• This head is a normal two-parent non-force descendant of prior semantic head 6214e88a1bab5404f1859505c56a5b1cc0479eef and current protected develop.
• The only intervening protected delta from the old base 749511c3ad4000090048718f685c6bee6b3d2c25 was apps/desktop/src-tauri/Cargo.lock; this coverage owner adopts that protected blob exactly and does not own it. Fresh develop...HEAD comparison reports behind_by=0 and exactly five semantic files: CHANGELOG.md, apps/desktop/vite.config.ts, docs/engineering/acceptance-criteria.md, packages/shared-types/test/coverage-policy.test.ts, and packages/shared-types/vitest.config.ts.

TDD lineage

• RED contract commit db5700ee073e603d4839fdad09e1990a197183df added packages/shared-types/test/coverage-policy.test.ts while packages/shared-types/vitest.config.ts still required only 90% for all four metrics. Hosted RED was not observed before the causal source repair, so that commit is not claimed as executed RED evidence.
• GREEN source commit 2f66cf65a03630f5d99da537b6ea09d6d806f944 raises the shared-types thresholds to 100% without changing its configured source set.
• 0be7f03e01a156e2740e86840c1f736de5675125 updates repository acceptance criteria.
• 707dd3bb564e07ad48d18bbfc98fa2f89811025c preserves the full changelog history after recording the expanded JavaScript coverage floor. Intermediate changelog-only commit c94ba18de7aaa5acc1db3e9c86b8dcf937a03433 is superseded by that immediate corrective descendant and must not be evaluated in isolation.
• 6214e88a1bab5404f1859505c56a5b1cc0479eef binds the regression guard to the typed threshold object actually consumed by shared-types Vitest rather than source-text inspection.
• 47ef7945fa9df371d5226b5f8e872315249902bd reconciles the protected base without altering the five-file coverage semantic delta.

Review state

Fresh review-thread verification on the predecessor semantic delta found every prior finding resolved: the shared-types 90→100 mismatch, accidental changelog truncation, text-based threshold inspection, generic file-read test path, and wrong-scope review assumption have all been repaired or withdrawn. Because the head changed during the protected-base restack, those historical resolutions remain useful finding history but do not substitute for fresh exact-head checks or a qualifying last-push approval.

Verification

Fresh hosted verification is required on exact current head 47ef7945fa9df371d5226b5f8e872315249902bd for desktop/shared-types tests and coverage, lint/typecheck where applicable, documentation checks, and every protected required workflow. Queued, pending, absent, failed, neutral, skipped-required, cancelled, predecessor-head, self/author, model-only, or administrative-bypass evidence is non-passing.

Security Notes

No runtime boundary, dependency, URL, subprocess, IPC, file-ingestion, model, export, or production-source coverage denominator is added or relaxed. The change only strengthens repository-owned JavaScript coverage enforcement and its executable policy guard.

Merge gate

Keep Draft and unmerged until the unchanged exact current head has every applicable protected required check terminal-success, zero valid unresolved current-head review findings/threads, and a qualifying independent non-author last-push approval. Never self-approve, force-push, weaken protection, or transfer predecessor evidence.

Merge Risk: 🟡 Moderate · up to db570

The PR raises the desktop coverage gate to 100%, but its new policy test targets the shared-types configuration and relies on a generic file-reading API, so the validation does not currently verify the intended desktop behavior and may fail in the repository checks. The test should be corrected before merge.

[seonghobae]

Current-head coverage evidence for f6e7d6e6ee12bd0e6c8e378ca100aabb4f11352c exposed a central workspace-install defect: the trusted coverage lane discovered apps/desktop but checked only that directory for package-lock.json, while this npm workspace owns the lock at repository root. Central .github PR #1411 fixes the bounded ancestor-lock installation and adds a regression contract: ContextualWisdomLab/.github#1411

The product PR remains unchanged and its local/hosted product checks are passing; no merge is requested until the central coverage gate is repaired and fresh exact-head evidence is produced.

Noema LLM review

The PR successfully raises Vitest coverage thresholds to 100% for both the desktop application and the shared-types package. It introduces a robust regression guard in packages/shared-types/test/coverage-policy.test.ts that imports the active configuration object directly, eliminating the risk of text-based bypasses. The changelog is correctly updated without history loss, and the engineering acceptance criteria now formally document the 100% coverage requirement.

Reviewed changed lines

• packages/shared-types/vitest.config.ts:3 (RIGHT): Exports a typed coverageThresholds object with all metrics at 100, ensuring a single source of truth for both the Vitest runner and the policy test.
• packages/shared-types/test/coverage-policy.test.ts:1 (RIGHT): Imports the active coverageThresholds object directly, ensuring the test fails if the actual configuration is lowered.
• apps/desktop/vite.config.ts:31 (RIGHT): Correctly raises desktop coverage thresholds from 90 to 100 for lines, functions, branches, and statements.
• docs/engineering/acceptance-criteria.md:28 (RIGHT): Formalizes the 100% coverage requirement in the repository's definition of done.
• CHANGELOG.md:13 (RIGHT): Accurately records the threshold increase in the changelog without truncating previous release history.

Adversarial validation

• packages/shared-types/test/coverage-policy.test.ts:1 (RIGHT) falsified: The test could pass even if the active shared-types coverage threshold were lowered due to stale imports or source-text scanning. — The test uses expect(coverageThresholds).toEqual(...) on the imported object. Changing the exported object in vitest.config.ts directly changes the input to the test, causing an immediate failure.
• packages/shared-types/vitest.config.ts:3 (RIGHT) falsified: The exported coverageThresholds object might be a decoy, while defineConfig uses a different internal object. — The defineConfig call explicitly uses thresholds: coverageThresholds, linking the exported object to the active configuration.
• Residual risk: The regression guard test is only implemented for shared-types. While apps/desktop thresholds are raised to 100%, there is no corresponding unit test to prevent a developer from lowering them in the future without running the full test suite.
