Record Eval A and Eval B grid results in status docs

Eval A grid ran clean across all scenarios/tiers. Eval B grid (1 rep/cell)
shows a real gap: haiku never unprompted-consults the ADR system in any
scenario, while sonnet passes 5/8 (misses W3 write-trigger and R1 direct-
conflict retrieval). Updates CLAUDE.md component status and the eval-b
README so the next session picks up from here instead of re-running blind.

 - Hook: `hooks/session_start.py` wired via plugin-relative `hooks/hooks.json` (`${CLAUDE_PLUGIN_ROOT}`, no `settings.json` entries) — deterministic existence check: present → near-zero-token usage note naming `/os-adr:create` + `/os-adr:find`; absent → once-per-day init/migrate suggestion, silenced permanently by `.os-adr/suppress` (gitignored per-project state dir); silent outside git projects.
 - Skills (verb-first, no `commands/`): `create` (one-invocation templated+numbered+indexed ADR with mechanical supersession), `init`, `migrate` (non-destructive: detect surveyed shapes → mechanical heuristic fill → LLM fills only manifest-listed interpretive fields via `--apply-fills` → `migration_confidence` frontmatter + `docs/adr/migration-report.md`; old-system deletion only as an explicit separate user-approved step), `find` (deterministic-first retrieval: affected-paths/components match → Accepted-only filter → one-hop Graphify query-path expansion with graceful degradation → AI judgment over the candidate set only).
 - Migration pilot passed 2026-07-03 (sandboxed project copies; gate threshold 25% low-confidence flags): viking-warrior-training-log 0%, delta-refinery 0%, llf-schema 8.3%. Retrieval verified end-to-end against the real llf-schema project graph. Resolved: ADRs need no Graphify tag/edge convention — retrieval layer 3 expands the *query* paths via graph-node `source_file`s.
-- Eval A harness (2026-07-03, ADR-021): `plugins/os-adr/eval/` — prompted skill-execution eval across model tiers (haiku/sonnet). Two fixtures (generated with the plugin's own CLIs), six scenarios (S1 create, S2 create+supersede, S3 find/conflict, S4 find/distractor, S5 init, S6 migrate+fills), deterministic Ruby checker (`eval/bin/check`, structural invariants, TSV mode for autoresearch), sandbox + headless-runner scripts, runner-prompt template. Primary run mode: in-session Agent-tool subagents with pinned `model:` (cheaper than `claude -p`); optimized via the `/autoresearch` Classic loop over SKILL.md *wording only* (checker/fixtures/scenarios frozen during a loop). Procedure: `plugins/os-adr/eval/README.md`. Self-tested both directions; grid not yet run. Distinct from the held-out Eval B (unprompted behavior) — do not conflate.

 - Vault graph: `~/Documents/SecondBrain/graphify-out/` — disposable, structural index rebuilt by SessionStart hook; handles relational/graph queries. Distinct from vault-index.json (planned, Plan B Phase 1): a flat `{tag: [{path, title, summary}]}` lookup rebuilt at SessionEnd, queried by the `/memory-find` skill for fast tag-based SB note discovery.
