Till JS 68c0eb2892 chore(test + audit): add test-coverage audit + wire audit:all

#6 test coverage (pivot to reporting): 34/653 tests currently fail
(in-flight spaces-foundation migrations). Hard coverage thresholds
aren't enforceable until the suite is green, so this session ships a
file-presence audit instead of line-coverage gates.

  - scripts/audit-test-coverage.mjs — counts .svelte + .ts source files
    vs .test.ts + .spec.ts per module. Reports total ratio, lists
    modules with 0 tests + ≥3 source files (prioritised by size).
  - pnpm run audit:test-coverage  wires it into audit:*.
  - docs/optimizable/test-health.md — state + prevention path + top
    untested modules ranked by impact.

Current baseline: 2.6% file-level coverage. 66/78 modules have zero
tests. Biggest untested: times (32 src), articles (29), events (27),
inventory + skilltree (20 each).

#8 audit:all: single entry point for the reporting audits. Runs
port-drift + i18n-coverage + test-coverage in --summary mode. Distinct
from validate:all (which is gates, not reports).

Test Health

Status 2026-04-22. Run pnpm run audit:test-coverage for live numbers.

Current state

34/653 tests currently fail. Related to in-flight spaces-foundation migration work (app-registry, api-keys, base-client, crypto record-helpers). Hard coverage thresholds aren't enforceable until the suite is green.
File-level "coverage" is 2.6%. 22 test files vs 857 source files (.svelte + .ts). 66 of 78 modules have zero tests.
12 modules have ≥1 test file. Hotspots (todo, times, body, a handful of critical infra) are partially covered; long tail is not.

Why file presence, not line coverage

Running vitest --coverage requires the suite to pass. Until the 34 failing tests are fixed, coverage numbers are undefined. In the meantime, "does this module have any automated regression protection?" is a useful signal for prioritising the next session.

Top untested modules (by source file count)

Module	Source files	Priority
times	32	HIGH — time-tracking logic, billing-adjacent
articles	29	HIGH — reader pipeline, bookmarklet, parsing
events	27	MED — RSVP / calendar interactions
inventory	20	MED — user-owned item schema
skilltree	20	MED — XP / level math
library	19	LOW — simple CRUD
photos	17	MED — upload / storage paths
wetter	17	LOW
calc	16	MED — arithmetic correctness
meditate, news, quotes, cards, core, moodlit	13–16 each	mixed

Prevention path

Fix the 34 failing tests first — they're noise blocking any real coverage work.
Run vitest --coverage — capture a baseline per module.
Add thresholds to vite.config.ts test.coverage.thresholds — start lax (50% for modules with tests, ignore untested), tighten over time.
Make pnpm run test:coverage part of validate:all — only after (1) is done.

For now: audit:test-coverage is the contract.
