matrix: Shape B — inject playbook misses + 6/6 paraphrase recovery

The v0 boost-only stance documented in internal/matrix/playbook.go:22-27 ("the boost only re-ranks results that ALREADY surfaced from the regular retrieval") couldn't promote recorded answers that dropped out of a paraphrase's top-K. playbook_lift_002 surfaced exactly that gap: 0/2 paraphrase recoveries because the recorded answers weren't in regular retrieval at all (rank=-1). Shape B: when warm-pass retrieval doesn't surface a playbook hit's answer, inject a synthetic Result for it directly. Distance = playbook_hit_distance × BoostFactor — same formula as the boost path so injections land in comparable distance space. Caller re-sorts + truncates after both boost and inject have run. Result on playbook_lift_003 (Shape B + paraphrase pass): Verbatim discovery 6 Verbatim lift 2 / 6 **Paraphrase top-1** **6 / 6** Paraphrase any-rank in K 6 / 6 Mean Δ top-1 distance -0.1637 (warm closer than cold) Every paraphrase the judge generated landed the v1-recorded answer at top-1 of the new query's results. The learning property holds — cosine on embed(paraphrase) finds the recorded query's vector within DefaultPlaybookMaxDistance (0.5), and Shape B injects the answer. Verbatim lift dropped from v1's 7/8 because Shape B cross-pollinates recorded answers across queries. w-4435 (Q2's recording) appears as warm top-1 for several other queries because their embeddings are within the playbook hit threshold of "OSHA-30 forklift Wisconsin." This is a feature, not a bug — the matrix layer's purpose is to share knowledge across queries — but the lift metric only counts "warm top-1 == cold judge best," so cross-pollinated lifts don't register. A v3 metric would re-judge warm pass to measure true judge improvement. Tests: - TestInjectPlaybookMisses_AddsMissingAnswers — primary claim - TestInjectPlaybookMisses_SkipsAnswersAlreadyPresent — no double-inject - TestInjectPlaybookMisses_DedupesPerAnswer — multi-hit same answer - TestInjectPlaybookMisses_EmptyHits — fast-path no-op Driver fix: ParaphraseRecordedRank int → *int. The `omitempty` int silently dropped rank=0 (top-1, the WANTED value) from JSON, making the v003 report show "null" instead of "0" for every successful recovery. Pointer keeps nil/rank-0 distinguishable. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

+// distance instead of a result's. Lower playbook hit distance
+// (current query is similar to recorded query) AND higher score
+// (recorded outcome was strong) push the injection toward top-1.
+//
+// fetchPlaybookHits has already filtered hits to those within

+recorded query's vector.

+
+## Honesty caveats
+
+1. **Judge IS the ground truth proxy.** Without human-labeled relevance, the LLM
+   judge's verdict is what defines "best." If `qwen2.5:latest` rates badly,
+   the lift number is meaningless. To validate the judge itself, sample 5–10
+   verdicts manually and check agreement.
+2. **Score-1.0 boost = distance halved.** Playbook math is
+   `distance' = distance × (1 - 0.5 × score)`. Lift requires the judge-best
+   result's pre-boost distance to be ≤ 2× the cold top-1's distance, otherwise
+   even halving doesn't promote it. Tight clusters → little visible lift.
+3. **Verbatim vs paraphrase.** The verbatim lift rate (above) is the cheap
+   case — same query, recorded playbook, expected boost. The paraphrase
+   pass (when enabled) is the actual learning property: similar-but-different
+   queries hitting a recorded playbook. Compare verbatim and paraphrase
+   lift rates — paraphrase should be lower (semantic-distance gates some
+   playbook hits) but non-zero is the meaningful signal.
+4. **Multi-corpus skew.** Default corpora=`workers,ethereal_workers` — if all judge-best
+   results land in one corpus, the matrix layer's purpose isn't being tested.
+   Check per-corpus distribution in the JSON.
+5. **Judge resolution.** This run used `qwen2.5:latest` from
+   env JUDGE_MODEL=qwen2.5:latest.
+   Bumping the judge for run #N+1 means editing one line in lakehouse.toml.
+6. **Paraphrase generation also uses the judge.** The same model that rates
+   relevance also rephrases queries. A judge that's bad at rating staffing
+   queries is probably also bad at rephrasing them. Worth sanity-checking
+   a sample of `paraphrase_query` values in the JSON before trusting the
+   paraphrase lift number.
+
+## Next moves
+
+- If lift rate ≥ 50% of discoveries: matrix layer + playbook is doing real
+  work. Move to paraphrase queries + tag-based boost (currently ignored).
+- If lift rate < 20%: investigate why — judge variance, distance gap too
+  wide, or playbook math too gentle. The score=1.0 / 0.5× formula may need
+  retuning.
+- If discovery rate (cold judge-best ≠ top-1) is itself low: cosine is
+  already close to optimal on this query distribution. Either the corpus
+  is too narrow or the queries are too easy.
