Security-relevant and the right fix. A Basic gate on the whole `/docs` path was a deploy bandage that also locked LAN operators out of `https://<lan>:20128/docs`; dropping the four operator-internal writeups from the fumadocs glob and the Docker image removes the reason for the gate instead of papering over it. Keeping them in git and citing repo paths from the public pages is the right trade. The `.dockerignore` matcher walking rules in file order with last-match-wins is a genuine correctness fix in the test's own matcher.

Validated in one consolidated worktree cut from `release/v3.8.51`, boarded with the other 19 PRs of this batch. Two in-batch conflicts, both additive and resolved by keeping each side: the `ENVIRONMENT.md` table (#13035 + #13011) and the `chatHelpers.ts` import block (#12975 on the tip + #13017).
- `typecheck:core` clean; `check:dashboard-typecheck` OK (206 pre-existing, within baseline); `check:changelog-integrity` OK; `check:docs-counts` migrations ✓
- complexity 2816 / baseline 3218 and cognitive-complexity 1271 / baseline 1437 — both under baseline
- 531 of 532 focused assertions green across the batch's 46 test files
- `check-file-size` rebaselined for the batch's real growth (annotation `_rebaseline_2026_09_11_mergebatch_v3851_houminxi`, landed on #13038), attributed per PR
The single red is **not this batch**: `tests/unit/combo/quota-weighted-strategy.test.ts` → "A/B isolation: 7 hard-empty + 2 at 0.5% + 1 at 40%, floor=1" asserts an order between two connections of identical weight and flakes on the pure tip too — 2 failures in 4 runs at `origin/release/v3.8.51` with nothing from this batch applied.
⚠️ base-red inherited: #12732 — `Docs Gates`, `Merge integrity`, `No new ESLint warnings`, `Unit Tests fast-path` and `Fast Quality Gates` reproduce on the pure tip (provider count 356 vs the 358 the modules define, SKILL.md drift, and `open-sse/utils/stream.ts` at 3115 > frozen 3098, untouched here).
Thanks @HouMinXi — the live evidence on these (X500 logs, `storage.sqlite` state, real `/v1/models` probes, the 36-minute outage write-up) is what let a 20-PR batch be reviewed as a unit.
Resynced onto the release tip after #12051/#12052/#12053 landed. Same LKGP-clear conflict as #12053 (kept the current clearStaleLKGP() helper at both call sites). One additional issue this final phase's combined-worktree validation surfaced: clearStaleLKGP() itself (added by #12013, which none of the 4 phase PRs could have seen since it landed after they were authored) still had a dynamic `await import("@/lib/localDb")` — a real break once this PR deletes the barrel. Fixed to `await import("@/lib/db/settings")`, matching the direct-import pattern used at every other call site. typecheck:core, check-db-rules, check:cycles, and the eslint-import-boundaries regression test (3/3, including "G14 rejects localDb barrel imports") all green after resync — zero barrel-importing production files remain. Nice clean 5-phase migration, and thanks for taking on the full #11795 cleanup.
