docs(agents): correct the ADR-0020 gate counts to measured state

The bullet is always-loaded context, and all three of its numbers had gone
stale as the issue #99 retrofit landed. Measured now: 19 of 39 descriptions and
7 of 39 bodies over their FAIL tier, down from 26 and 9; one dangling routing
target left (research -> neuledge-context), down from two.

Kyberforge.CompositionNote fired 10 errors across four gitea-* skills and now
fires nowhere -- those four were the only carriers and all four have been
retrofitted. The 'check both gates' advice stays: skill-size-check still does
not cover the Vale half, and any new description can reintroduce the rule.

 - **Do not add repo-owned keys to `.claude/settings.json`.** apm treats it as its own deployed artifact and `apm audit --ci` replays the install and diffs, so anything apm would not have written is permanent drift that fails the `apm-audit-ci` pre-push hook. A hook you want here is authored in `plugins/<name>/.apm/hooks/` and deployed by apm, never hand-written into that file. The `SessionStart` entry already in it is exactly that: kyberforge authors it in `plugins/kyberforge/.apm/hooks/hooks.json` and apm merges it in, so it is apm's own output, it is what the replay expects, and it belongs in the commit — do not strip it (ADR-0019). Machine-specific settings go in the gitignored `.claude/settings.local.json`; shared enforcement goes in `.pre-commit-config.yaml`.
 - **`apm.lock.yaml` turning up modified is expected, not a bug.** kyberforge's `SessionStart` hook runs `apm outdated` at startup and `apm update --yes` when something is behind, which rewrites the lock. Commit or discard it deliberately.
 - **A `.apm/` edit is not live in this session until it is pushed.** The six dependencies resolve from the holocron remote, unpinned against the default branch. `apm install` deploys from the lock; `apm update` is what re-resolves refs.
-- **The ADR-0020 skill gates ship hot, with no baseline.** 26 of 39 descriptions and 9 of 39 bodies exceed their FAIL tier, and the `Kyberforge.CompositionNote` Vale rule fires 10 errors across `gitea-issues`, `gitea-labels-milestones`, `gitea-prs` and `gitea-workflow`. Editing any of those skills *for any reason* means retrofitting it to the contract first — a one-line fix cannot be committed until the skill complies. Deliberate; tracked as Gitea issue #99. `skill-size-check` will not warn you about the Vale half, so check both: `pre-commit run --all-files`.
+- **The ADR-0020 skill gates ship hot, with no baseline.** 19 of 39 descriptions and 7 of 39 bodies exceed their FAIL tier, and one routing target still dangles (`research` → `neuledge-context`). Editing any of those skills *for any reason* means retrofitting it to the contract first — a one-line fix cannot be committed until the skill complies. Deliberate; tracked as Gitea issue #99, which is retrofitting the corpus plugin by plugin. The `Kyberforge.CompositionNote` Vale rule currently fires nowhere, but `skill-size-check` does not cover the Vale half and the rule can be reintroduced by any new description, so check both: `pre-commit run --all-files`.
 - **Run `bash tests/run-tests.sh --strict` before considering any change done.** Keep the flag: without it a suite whose dependency is missing exits 77 and is counted SKIPPED rather than failed, so the run goes green having verified less than it claims.
 - **Before pushing, rehearse the gate locally:** `pre-commit run --hook-stage pre-push --all-files`. It runs the 14 pre-push hooks this repo authors itself plus pre-commit's 2 `meta` hooks, so it prints 16; `check-release-needed` passes without checking anything, because it needs a real push to `main`. `docs/spec/gates.md` reconciles both.
 - **Pushing without a network** needs `SKIP=apm-marketplace-check,apm-pack-check-clean git push` — those two resolve a remote marketplace entry via `git ls-remote`. Skip only those two; the rest are real local checks, and adding one to `SKIP` disarms it silently.
