0.11 retrieval-quality gate hardening: expand golden set + blocking self-eval audit

[mobileskyfi]

Part of the 0.11.0 release quality bar (milestone) and umbrella #28's "did we regress from the HTML corpus" concern. Sibling of #26 (which fixes the two known regressions); this issue widens the net so unknown ones surface before stable.

Why

The Phase 0 golden set (fixtures/eval/queries.json) is 24 queries: 12 nl, 5 device, 3 cmd, 2 version, 1 topic, 1 ambiguous. Three whole retrieval surfaces have zero golden coverage: property lookups (routeros_lookup_property), changelog search (routeros_search_changelogs), and video/segment search. The corpus swap to Docusaurus (T-0035/T-0036) changed indexed prose for all of them; today nothing would tell us if one regressed.

Scope

1. Expand the golden set 24 → ~35, minimums per category:
   • +4 property queries (mix of exact path+name lookup and free-form, e.g. a queues property, a wifi property that moved pages in the new manual);
   • +3 changelog queries (a fixed-CVE style query, a feature-introduced query, a version-scoped one);
   • +2 video queries (topic phrasing that should hit a known transcript segment);
   • +2 additional nl queries in areas the old HTML corpus handled well (pick from B-0012's migration notes / bench-routeros-tools fixtures if stable).
     Every new query verified against the live current corpus before committing; expected pages keyed by rosetta_id (never numeric id).
2. One audit run of the self-supervised eval in blocking mode — qa.yml dispatch with eval_self_blocking=true against a fresh local build. Record pass/fail + any per-query findings in a comment here; decide whether any finding earns a golden-set row or an issue. This does not flip the default (self-eval stays non-blocking).
3. Thresholds sanity pass — confirm _thresholds in queries.json still expresses the intended floor once the set grows (a 2-failure tolerance over 24 means something different over 35). Document the rationale inline in _doc.
4. Regenerate fixtures/eval/baseline.json; if Retrieval ranking regressions from Docusaurus corpus swap (nl-firewall-filter, nl-bgp golden queries) #26's fix lands first, rebase on top of it (expected — Retrieval ranking regressions from Docusaurus corpus swap (nl-firewall-filter, nl-bgp golden queries) #26 is sequenced first in the beta window).

Acceptance criteria

• Golden set ≥ 35 queries with the per-category minimums above; all new queries green against the live corpus (or failing loudly and intentionally, called out in the PR like Retrieval ranking regressions from Docusaurus corpus swap (nl-firewall-filter, nl-bgp golden queries) #26's two).
• Maintainer reviews the chosen queries + expected pages in the PR (query selection is judgment; the PR description lists each new query with a one-line "why this page is the right answer").
• Blocking self-eval audit run performed and findings recorded in a comment.
• _thresholds reviewed; _doc explains the floor.
• baseline.json regenerated; make verify green; no changes to src/query.ts in this issue (ranking fixes belong to Retrieval ranking regressions from Docusaurus corpus swap (nl-firewall-filter, nl-bgp golden queries) #26).

Validation: V-retrieval-floor. Relevant instructions: query-core-not-adapter. Grounding: briefings/B-0010-mcp-eval-phases-3plus.md (this is a slice of its Phase 1–2 thinking, kept deliberately small), briefings/B-0012-docusaurus-manual-migration.md.

Run the qa.yaml with git@e45d98f (current main)

• with eval_self_blocking=true, FAIL (expected at this point), see https://github.com/tikoci/rosetta/actions/runs/29210060933
• with default (eval_self_blocking=false, PASS (expected since non-gate), see https://github.com/tikoci/rosetta/actions/runs/29210202950

One-off "compare-and-constrast" against 0.10.0 benchmarks critical

IDK if we've reset the baseline, but do want to ensure we make forward progress without regressions on the number from the 0.10 release. This is critical to know, and be well grounded (not assuming main's baseline#s == 0.10.0 => check with CI/re-run-as-needed). Note this does not have be a durable test going forward - since it's not like going back the HTML is an option - but doc content is a bigger change than other work we've done, that could have regressions. Going forward we can obviously set the baseline after the results of this work.

Golden set ≥ 35 queries against 0.10.0?

Ideally (e.g. if reasonable possible), run the new "Golden set ≥ 35 queries" against 0.10.0, so gather a bit more data the historic golden set as a final double-check on our work on Confluence->Docusaurus effort.

Audit deliverables (PR #57)

Grounded against three real DBs — a fresh local make extract (Docusaurus, live manual.mikrotik.com, 363 pages), the clean published v0.10.0 release DB (Confluence, 321 pages), and a v0.10.0 copy with empty schema-v8 tables backfilled so current searchAll can run against it. Full write-up: briefings/B-0020-0.11-retrieval-quality-audit.md.

1. Blocking self-eval audit (eval_self_blocking=true)

Reproduced the maintainer's CI FAIL (run 29210060933) locally. Verdict: the tooling is fine; the baseline was stale.

• Every absolute strategy floor PASSES on the current corpus: title hit@5 96.7% (≥90), section hit@10 78.8% (≥65), property hit@10 80% (≥55), cmd-path hit@5 70% (≥70), overall MRR 59.4% (≥45).
• The FAIL was regression-vs-baseline only, and self-supervised-baseline.json was generated 2026-04-22 against the Confluence corpus — never regenerated after the T-0035/T-0036 swap. So every post-swap run shows a phantom ~5–7pp regression.
• Top misses are generic ambiguous headings ("Example Add SafeSkill security badge (73/100 — Passes with Notes) #1", "Configuration example", "Read-only properties") — inherent low signal of the section strategy, not retrieval bugs. No golden-set row warranted.
• Action: regenerated the baseline against Docusaurus (200 queries) → blocking rehearsal now green. Counts as rehearsal Add SafeSkill security badge (73/100 — Passes with Notes) #1 of the ≥3 in the V-retrieval-self promotion path. Default stays non-blocking (not flipped).

2. 0.10.0 compare-and-contrast (one-off, not a durable gate)

New src/eval/corpus-compare.ts matches on a corpus-agnostic topic token (v0.10.0 has no rosetta_id, so page-recall can't be compared directly):

Aggregate: 0.10.0 14/16 (88%)  →  current 14/16 (88%)
✅ No topic-level regression vs 0.10.0 on the compared queries.

The existing 24-query golden set also scores 91.7% Recall@5 / 86.8% MRR / 100% classifier on the current corpus — at/above the pre-swap baseline. The corpus swap did not degrade retrieval. (Answers "did we reset the baseline?": no reset needed — current ≥ 0.10.0.)

Premise correction for #26: its two "regressions" (nl-firewall-filter, nl-bgp) miss on 0.10.0 Confluence too (firewall top-5 = ROSE-storage/General-Properties/First-Time-Config/Scripting/HotSpot; BGP = Routing-Overview/VRF/DHCP). So #26 is a pre-existing query-core weakness, not swap-induced — commented there.

3. _thresholds review

Recomputed for 27 search queries: recall@5 0.88, recall@3 0.82, mrr 0.75, classifier 0.90 (was 0.85/0.70/0.65/0.85, which tolerated 4 failures over the larger set). Keeps the pre-#53 "≈2-failure" spirit; the 2pp regression check vs baseline remains the tight forward guard. Rationale inline in _doc.

4. Bug Ledger — ETL/MCP issues surfaced (not hidden; no fixture loosened)

• BL-1 command-path→page→property link broken on core menus (/ip/firewall/filter action → 0 HIGH; /ip/dhcp-server address-pool → HIGH to the wrong page). Pinned by known-failing prop-firewall-filter-action. Follow-up issue filed.
• BL-2 noisy commands.page_id links (/ip/service/print→containers). BL-3 dotted WiFi properties not extracted (/interface/wifi channel.width → 0 rows). Both folded into the BL-1 follow-up.
• BL-4 classifier false-positive: "port forward to an internal server" → parsed as a command path.
• BL-6 searchAll crashes on a pre-v8 DB (no such table: device_aliases) — no graceful degradation.

Acceptance criteria

• Golden set ≥35 with per-category minimums; new queries green (or failing loudly + called out)
• Blocking self-eval audit performed + findings recorded (here)
• _thresholds reviewed; _doc explains the floor
• baseline.json regenerated; make lint/bun test/eval green; no src/query.ts changes
• Maintainer reviews the chosen queries + expected pages (PR #53: retrieval-quality gate hardening — golden set 24→35 + direct-surface eval matrix #57 table)
