[CLAUDE] Docs: S51 session-end closeout — error-ledger §L + monitor spawn-records + root counts

§L.a/b: E-002 RESOLVED (gotcha #57 LeaveType/Shift/OtPolicy filtered Mig 45) + NEW E-007/AS-11 (parallel-fan-out FE<->BE contract mismatch, reviewer-caught pre-commit) + Active-Guards (#57 guard 2->3 verified + reviewer cross-stack guard). H2 GATE PASS 5/5 + H1 CHOT 4-mat spawn-records appended (both wrote 0 files - E-006 backstop held). CLAUDE.md root counts 43->45 mig / 91->92 tables / 181->186 test. HANDOFF: database-agent /adap-apply recommend next-session + doc-drift backlog coords. CI-skip (docs/.md only).

 - **2026-06-07 (CREATED):** Seeded H2 harvest-curator (adopt AI_INFRA Harness 1, anh giao). Tailored SE: 4 RAG-read · `model:inherit` · omit color · Fidelity-escalate → SE `reviewer` (KHÔNG AI_INFRA-specific). Wired @session-end §L.b GATE (nâng 3/5→5/5 trục) + @session-start RE-REPORT harvest-mới (Phase 2.1.1) + Harness 2 B5 wave-gom. Nấc: **executed-file, verified-runtime PENDING** CLI restart + first spawn smoke. Tag [created, harness-1, h2].
 - **2026-06-07 (S50 FIRST REAL RUN — verified-runtime ✅):** Spawned @session-start (harvest RE-REPORT) + @session-end (5-trục GATE + B5 wave-gom). Load OK → **verified-runtime CONFIRMED**. @start: harvest 🟢 clean. @end: **GATE PASS 5/5** (Coverage 4 subs · Completeness 4-field · Placement correct homes · Corruption 0-byte/mojibake=0 · Fidelity no-flag — independently re-verified inv-codebase `.gitignore:93` claim). **B5 wave-gom executed:** 2 wave sub-MDs → propose APPEND agent-memory/{investigator-codebase,test-specialist} (em main wrote). B6 re-verify HELD (git diff agent-memory EMPTY). **Method-learning (⭐):** chunk-count CANNOT verify via Bash `curl localhost:6333` — RAG MCP points at DIFFERENT Qdrant host → collection 'not found' false-negative. Use **RAG MCP channel** (`list_projects`) for chunk-count, NOT shell probe; em main (single RAG-writer) = authoritative (confirmed 2415). Tag [first-run, verified-runtime, gate-pass, chunk-via-mcp].
+- **2026-06-08 (S51 `/session-end` 5-trục GATE — DIRECT spawns, RAG down):** Verified 6 product subs · nấc=**verified-runtime** (on-disk ground-truth, **0 file written**, git-diff agent-memory clean = E-006 backstop ✅) · evidence=**GATE PASS 5/5** (Coverage 6/6 S51 entries · Completeness 4-field · Placement correct · Corruption 0-byte=0 + investigator-killed file intact 92L terminates-clean + mojibake/shell-bake=0 · Fidelity reviewer-proxy honestly-marked + "1 MAJOR" claim ground-truthed `HrmConfigsPage.tsx:132-134`). B5 wave-gom **n-a** (DIRECT spawns, no `wave-*/`). 3 non-block flags → em main: (1) test 185→186 honest RED→GREEN (raw 174 attrs→runtime 186) (2) cicd self-tag [s50]→should-be-s51 cosmetic (3) Mig 45→92 tables, CLAUDE.md stale 43→91. **Method-learning ⭐:** killed-mid-write sub → verify file **terminates cleanly** (`wc -l`+tail+closing-Tag), NOT just `-size 0` (partial-write = truncated tail not 0-byte). Tag [s51, gate-pass, killed-sub-verify, direct-spawns].
