feat+test+docs: D44 — lib/keys.mjs core landed (multi-key auth, no server wire-up yet) (#20)

* feat+test+docs: D44 — lib/keys.mjs core landed (multi-key auth, no server wire-up yet)

First Phase 2 implementation D-day. Lands the lib/keys.mjs module per
ADR 0007 §§ 5 / 6.1 / 6.3 / 6.3.5 / 6.4 / 9.4. Identity / lifecycle
layer for OLP API keys is now in-tree; server.mjs integration is
scheduled D45 (until then, requests still use the hardcoded
'__anonymous__' cache namespace — no behavioural change at v0.1.1 / D44).

NEW FILE lib/keys.mjs (~437 lines, public API):

  - createKey({ name, owner_tier, providers_enabled, notes, olpHome })
    Generates opaque 'olp_<32-byte base64url>' token (47-char total),
    SHA-256 hashes for manifest storage, atomically writes
    keys/<id>/manifest.json (file 0600, dir 0700). Returns
    { id, plaintext_token, manifest } — plaintext printed once, never
    persisted.

  - validateKey(plaintext, { allowAnonymous, olpHome })
    Three-tier resolution per § 5 / § 7 / § 9.4: env override
    (OLP_OWNER_TOKEN -> __env_owner__) -> anonymous (only when
    allowAnonymous: true, returns __anonymous__) -> filesystem
    manifest lookup (constant-time hash compare via timingSafeEqual).
    Revoked manifests return null (caller produces 401). Per § 6.3.5:
    MUST hit manifest every request; no in-process validation cache.

  - revokeKey({ id, olpHome })
    Idempotent; sets revoked_at via atomic write inside per-key lock.

  - listKeys({ olpHome })
    Returns manifest objects with token_hash redacted.

  - touchLastUsed(id, { olpHome })
    Async best-effort lazy update per § 6.3 revoke-dominates-touch:
    re-reads latest manifest inside per-key lock, NO-OPs if revoked_at
    is non-null, otherwise merges last_used_at preserving all other
    fields. Failure logs warn and never throws.

  Plus internal helpers: hashToken (SHA-256 hex), generateToken,
  generateKeyId, validateManifest (§ 4 schema validation), readManifest,
  writeManifestAtomic (tmpfile + fsync + rename + chmod), _withKeyLock
  (§ 6.4 in-process per-key write-lock chain), _safeHexCompare
  (timing-safe).

  Test-only hooks: __setTouchInterleaveHook (inject deterministic pause
  for race tests), __resetWriteLocks (test cleanup).

NOT IN D44 (split per ADR §§ 6.2 / 9.1 separation):

  - audit ndjson append (§ 6.2) — request-layer concern; D45 server glue
  - keygen CLI bootstrap surface (§ 9.1) — D45+ separate command entry
  - server.mjs integration replacing hardcoded '__anonymous__' at
    server.mjs:502, :531 — D45
  - owner-vs-guest gating for /health (server.mjs:392) + X-OLP-Fallback-
    Detail (server.mjs:1072, :1101) — D46

TEST COUNT: 468 -> 496 (+28 tests in new Suite 19):

  - 19a-d: token generation (§ 5)
  - 19e-j: manifest write+read + chmod 0600/0700 + schema validation
    (§ 4, § 6.1)
  - 19k-p: validateKey (filesystem / wrong / missing / anonymous /
    revoked / env override) (§ 5, § 6.3.5, § 9.4)
  - 19q-r: revokeKey idempotency + non-existent id
  - 19s-t: listKeys empty + redaction
  - 19u-x: touchLastUsed updates + NO-OP on revoked + NO-OP on
    anonymous/env identities + best-effort failure
  - 19y-1 to 19y-4: ACCEPTANCE CRITERION #7 — concurrent revoke + touch
    race tests:
      19y-1 revoke -> touch (revoked_at survives)
      19y-2 touch -> revoke (revoked_at + last_used_at both present)
      19y-3 interleaved external-revoke via __setTouchInterleaveHook
            (deterministically reproduces the § 6.3 race the
            maintainer's D43-B text review caught — confirms our impl
            observes the revoke and NO-OPs)
      19y-4 30-iteration concurrent Promise.all stress

* feat+test+docs: D44 fold-in — opus reviewer findings (2 P2 correctness + 2 P3 polish)

Fresh-context opus reviewer (PR #20) returned APPROVE_WITH_MINOR with 4
findings — 2 P2 real correctness gaps + 2 P3 polish. All accepted; the 2
P2 fixes ship with new regression tests.

P2 #1 — lib/keys.mjs _withKeyLock lock-map cleanup

  Prior version stored `prev.then(() => next)` as the Map tail, but the
  cleanup-identity check `_writeLocks.get(id) === next` could never match
  the derived promise. Result: Map entries leaked one-per-unique-key-id
  forever. Bounded impact at family scale (~5–10 entries) but a real
  correctness bug uncovered by reviewer empirical reproduction
  ("CLEANUP SKIPPED every call").

  Fix: store `next` directly as the Map tail. The chain still works
  because new callers chain off `_writeLocks.get(id)` (the prior caller's
  `next`); compare-and-delete by identity correctly cleans up when the
  current caller is the last in queue.

  Regression tests:
   - 19x-extra: after 5 sequential touchLastUsed calls, __writeLockSize()
     must be 0.
   - 19x-extra-2: after 9 concurrent touch calls across 3 keys (3 per
     key), __writeLockSize() must drain to 0.

P2 #2 — lib/keys.mjs validateKey non-string defensive coding

  Prior version threw TypeError when called with a non-string truthy
  plaintext (validateKey(42), validateKey({}), etc.), reaching
  hashToken(<non-string>) which calls createHash().update(<non-string>)
  which throws. Q2 (defensive-coding acceptance criterion) promised
  "bad inputs return null."

  Fix: top-of-function guard
  `if (plaintextToken != null && typeof plaintextToken !== 'string') return null;`
  Falls through to null path for non-string truthy; preserves existing
  null / undefined / '' handling.

  Regression test 19m-extra: validateKey(42), validateKey({}),
  validateKey([]), validateKey({ token: 'olp_xxx' }), and the same with
  allowAnonymous: true — all must return null without throwing.

P3 #3 — 19y-3 test scope comment clarification

  Reviewer noted that 19y-3 simulates external revoke landing BEFORE
  touch's read (not BETWEEN touch's read and write — currently
  unreachable due to synchronous read→write in touchLastUsed). Added
  explanatory comment documenting:
   - The scenario this test does cover (pre-read external revoke).
   - The scenario this test does NOT cover (between-read-and-write).
   - Why scenario 3 is unreachable in the current impl (no await between
     readManifest and writeManifestAtomic).
   - The trigger for adding a post-read hook (any future refactor that
     introduces an await between read and write).

P3 #4 — CHANGELOG line-count corrections

  D44 entry said ~330 lines (initial estimate); actual is 462 lines
  after fold-in. Test count claim updated from "+28 tests" to
  "+31 tests" (28 initial + 3 fold-in regression).

New module-level export: __writeLockSize (test-only) — reports current
size of in-process write-lock Map for the regression tests above. Not
intended for production callers.

Test count: 496 → 499 (+3 fold-in regression tests; +31 total from
D44 inclusive of initial Suite 19). Verified locally via npm test.

* docs: D44 fold-in #2 — CHANGELOG line-count consistency (trivial)

Delta opus reviewer flagged internal CHANGELOG inconsistency: header
bullet correctly stated `~462 lines` but the P3 #4 self-description
bullet still said the prior fold-in corrected to `~445 lines`. Both now
agree on 462 (matches `wc -l lib/keys.mjs`).

No code change. Test count: 499 / 499 pass (unchanged).

Authority: PR #20 delta opus reviewer trivial inconsistency note.

- **Streaming-path singleflight not implemented.** The cache layer's D4 singleflight (one spawn per identical concurrent request) is fully wired on the buffered path but NOT on the streaming path. N concurrent identical streaming requests at v0.1 will each spawn their own CLI process. Design ratified in [ADR 0005 Amendment 8](./docs/adr/0005-cache-cross-provider.md); implementation tracked via [issue #16](https://github.com/dtzp555-max/olp/issues/16) and [v1.x roadmap #1](./docs/v1x-roadmap.md). At family scale this is observably fine — every caller still receives the correct response; the cost is N CLI processes instead of one.
- **Soft triggers configured but inert.** `routing.soft_triggers` in `~/.olp/config.json` is honored by the engine's evaluation logic but `quotaStatus()` polling is not wired (ADR 0004 Amendment 2). A startup warning fires if the field is non-empty so the inert state is visible.
- **Multi-key auth not yet implemented.** All requests today share the cache namespace `__anonymous__`. The cache data model is keyed by `keyId` and ready to accept real identities when `lib/keys.mjs` lands. Phase 2 active: ADR 0007 drafting at D43-B, implementation D-days to follow. Tracked in [v1.x roadmap #2](./docs/v1x-roadmap.md).
- **Multi-key auth core landed, server integration pending.** `lib/keys.mjs` core (createKey / validateKey / listKeys / revokeKey / touchLastUsed) shipped at D44 per ADR 0007. All requests at v0.1.1 / D44 still share the cache namespace `__anonymous__` because `server.mjs` integration is scheduled for D45 — until that lands, the identity layer exists in-tree but no request flow consults it. Phase 2 in progress through D45 (server wire-up), D46 (owner gating), D47 (E2E + multi-key fixtures), Phase 2 close → v0.2.0. Tracked in [v1.x roadmap #2](./docs/v1x-roadmap.md).
- **Provider-level `cacheKeyFields` mask not implemented.** Cache keys include every IR field including ones individual plugins drop at spawn (e.g., Anthropic plugin drops `temperature`). Spurious cache misses possible (extra spawn cost; never spurious hits). Conservative posture documented in [ADR 0005 Amendment 7](./docs/adr/0005-cache-cross-provider.md). Tracked in [v1.x roadmap #5](./docs/v1x-roadmap.md).
