test: add coverage reporting with a threshold gate#117
Conversation

On it, @rubenhensen! I'm reviewing PR #117 now — checking the test coverage additions and CI regression gate for correctness and rule-compliance, and I'll post a consolidated review shortly. |

Reviewed the coverage + regression-gate change. Rule checks: all pass (conventional-commit title test:, Closes #107, no README/CSP/route/UI/security-note conflicts, dep is actually used, repo npm-audit-override policy untouched). Tests: 83/83 pass and the gate is green (33.55% stmt / 47.5% branch / 16.47% func / 33.57% line, all above the 30/40/15/30 floors).
No blocking issues — the gate is deliberately conservative and correctly locks in a no-regression floor. Two non-blocking nits inline about coverage scope and the tightest threshold margin.

nit: include: ['src/lib/**/*.{ts,js}'] also pulls in one-off DB migration files (src/lib/server/migrations/, e.g. legacy-api-keys.ts currently ~98%). Migrations aren't normally unit-tested, so a future untested migration would drag the overall percentages down and could trip this regression gate on an unrelated PR. Consider excluding 'src/lib/server/migrations/**' so the gate reflects testable lib code.

nit: the functions floor (15) sits only ~1.5pt below the 16.47% baseline (14/85 covered functions) — dropping a single covered function to 12/85 = 14.12% would trip the gate. Statements/lines (~3.5pt) and branches (~7.5pt) have healthier margins. Deliberate per the PR; just flagging it as the tightest margin to keep in mind when ratcheting thresholds up.

Reviewed! All rule checks pass, 83/83 tests are green, and the coverage gate is above its floors. Left two non-blocking nits in the review: migration files inflate the coverage scope a little, and the functions floor is your tightest margin worth keeping an eye on. Nothing blocking a merge. |

Regenerated package-lock.json from the merged package.json so both the main-side deps (pino, LICENSE) and this branch's @vitest/coverage-v8 are reconciled. 91 unit tests pass; coverage gate passes above thresholds. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Rules Dobby 2 — consolidated review (REQUEST_CHANGES)
The coverage gate itself works (gate passes exit 0, 91/91 tests green), and the mechanism is sound. But the conflict-resolution merge that brought this branch up to date (9528375) took the branch-side .github/workflows/ci.yml wholesale and silently dropped everything PR #118 ("scan and sign published container images") added to main. This PR is scoped to coverage only, so that deletion is an unintended security regression that must be restored before merge.
Evidence: on main (d1d23b1) ci.yml is 263 lines with 5 cosign references and an image-scan (Trivy) job; on this branch it is 204 lines with none. Merging #117 as-is would revert #118, which is already live on main.
Both the rule pass (Haiku sub-agents over ~/dobby-memory/rules) and Review Dobby 2 converge on the same three findings below — no additional distinct issues surfaced. conflict-resolution-check-noop, the repo security notes, and promised-vs-delivered all flagged non-compliance; PR-title, tests-required, and justification-paragraph rules all passed.
Findings
- (blocker)
ci.yml— the merge removedid-token: writefrom the finalize job, killing keyless cosign OIDC signing. - (blocker)
ci.yml— the merge deleted theInstall cosign+ keyless-sign steps AND the entireimage-scan(Trivy) job from #118. - (nit)
vite.config.ts/ PR description — the description's threshold table (30/30/40/15, baseline ~33.5/47.5/16.5/33.6) is stale; committed thresholds are 18/27/7/17 (retuned in366e435after excluding migrations).
Suggested fix: re-merge origin/main into the branch keeping BOTH the coverage change (the --coverage flag + vite.config.ts block) and #118's signing/scanning, then refresh the PR description's threshold table.
Caveat for the fixer: the fix touches .github/workflows/ci.yml. Per workflows-permission-recurring-blocker, dobby-coder[bot] may lack workflows:write — though dobby-yivi-agent[bot] already pushed the merge that modified ci.yml on this branch, so a push should be feasible here. If the push is rejected, deliver the ci.yml portion as a patch-in-comment. Also: this PR is currently ready-for-review with open blockers — consider flipping back to draft until the regression is resolved.

Blocker — security regression. The conflict-resolution merge (9528375) took the branch-side ci.yml wholesale and dropped id-token: write from the finalize job's permissions — the OIDC token required for keyless cosign signing added in #118. Net effect: merging #117 silently reverts #118 (already on main). Restore this permission when re-merging main.

Blocker — security regression. Everything after this line was deleted by the same bad merge: the Install cosign + Sign the published image (keyless) steps AND the entire image-scan (Trivy) job that #118 added to main. On main (d1d23b1) ci.yml is 263 lines / 5 cosign refs / one image-scan job; on this branch it is 204 lines with none. This PR is scoped to coverage only, so this is an unintended regression — re-merge main keeping both the coverage change and #118's signing/scanning.

Nit. The PR description's threshold table says statements 30 / lines 30 / branches 40 / functions 15 (baseline ~33.5/47.5/16.5/33.6), but the committed thresholds here are 18 / 27 / 7 / 17 (retuned in 366e435 after excluding migrations). Update the description so reviewers see the actual gate.

Hey @rubenhensen — found and fixed the regression, but hit a wall on the push. The conflict-resolution merge (#9528375) silently reverted PR #118 (container image scan + keyless cosign signing) that's live on main — it took the branch-side Blocked: Also refreshed the threshold table in the PR description (was stale at 30/30/40/15; now 18/27/7/17 post-migration-exclusion) and flipped the PR back to draft while this regression is outstanding. |

🧦 Dobby reviewed this PR (code review + per-rule compliance check).
The coverage gate itself is solid: scope is sensibly limited to src/lib/** with migrations excluded, thresholds sit a couple points below the measured baseline as a no-regression floor, CI enforces it via --coverage, and coverage/ is git/prettier-ignored. Tests pass (91/91), all above the floors. No rule violations in the coverage config, CI, or ignore changes.
One issue found:
- Unused
zodruntime dependency (see inline comment onpackage.json).zod@^4.4.3is added todependenciesbut imported nowhere in source. It's unrelated to this PR's purpose and should be removed or split out.
Requesting changes only for the stray zod dependency — the coverage work is good to go once that's cleaned up.

zod@^4.4.3 is added as a runtime dependency here, but zod is imported nowhere in the source tree (grep -rn zod src/ finds only Dutch words in locale files). This looks like a stray addition — it's unrelated to the coverage gate and contradicts the "keep lock minimal" intent of the cleanup commit (4c0bc48). Per our check-dep-is-used-before-bumping rule, a dependency should be verified as used before it's added. Please drop zod (and its lockfile entry) from this PR, or split it into its own PR alongside the code that actually uses it.

Closes #107.
Adds test-coverage measurement + a regression gate. Coverage wasn't measured before, so nothing stopped it eroding silently.
Changes
@vitest/coverage-v8added; coverage configured invite.config.ts(providerv8,text-summary+text+lcovreporters).src/lib/**(the unit-tested server/lib code; routes are covered by e2e). One-off DB migration scripts (src/lib/server/migrations/**) are excluded so an untested future migration can't trip the gate on an unrelated PR.vitest run --coverage, so the thresholds are enforced on every PR.coverage/added to.gitignoreand.prettierignore.Threshold
Measured baseline over
src/lib/**(migrations excluded) is ~20% statements / 30% branch / 9% functions / 19% lines (91 unit tests). Thresholds are set a couple of points below that:This locks in a no-regression floor without failing on the current state (latest run: 25.7% stmts / 32.5% branch / 10.1% funcs / 25.1% lines — all above floor). The intent is to ratchet these up as coverage improves — they're deliberately conservative for a first gate.
