## 2026-05-22 — S27 wrap-up retrospective em main proxy

Investigator pre-flight CRITICAL miss: nếu spawn pre-Plan A.3 (RAG manual control build) → would have catch Qdrant Web UI static missing PRE-em main write rag-dashboard.ps1 link `localhost:6333/dashboard`. Pattern reinforced: **pre-flight infrastructure audit MUST spawn Investigator** trước khi em main claim "X work" trong docs. Em main S27 SOLO miss external dependency check (Qdrant Web UI separate repo from binary). Anh pqhuy catch via UAT browser → escalate.

**Audit cumulative S20-S26 memory log entries claiming "Investigator spawn" - re-verify retroactive:** Per pitfall confirm spawn `investigator` agent type NOT FOUND trong session S27, có nghĩa registry chưa bao giờ load trong session này. Nhưng memory log S23 t1 K0 + S25 t1 audit Bug 1+2 + S26 Plan AG audit 5Q + Plan AI RAG research **đã ghi "spawn Investigator" với token cost 28-40K**. Possibility: (a) Previous sessions có registry load thành công (Claude Code version cũ hơn / file format khác / hot-reload sau /agents UI invoke), hoặc (b) Em main misattribute - actually spawn `general-purpose` agent default. Cần audit history Claude Code logs để xác minh - ngoài scope S27. **For now: trust prior memory entries but FLAG uncertainty cho future investigation.**

Archived 10 verbose Recent activity entries S21 → S24 Plan AA → `archive/2026-05-q1.md`. KEEP: S25 Bug audit + wrap, S26 Plan AG + Plan AI RAG, 2026-05-11 setup. Patterns proven section + Active workflow schemas section preserved. Memory size before: 34.9 KB → after: target ~20-22 KB.

## 2026-05-19 — S25 wrap Plan AB Bug 1+2 audit + 6 follow-up plans em main solo

Pre-Plan AB audit ~28K confirm root cause: Bug 1 Budget Adjust Handler ĐÃ log Changelog (Header+Update) nhưng FE HistoryTab filter strict TraLai-only loại. Bug 2 ApplyReturnModeAsync 4 mode KHÔNG add Changelog.Add() — chỉ caller LogTransitionAsync log phase transition. Recommended fix path: BE add log return mode + FE filter relax + Decision badge differentiation. **Em main solo từ Plan AC** (cross-stack reasoning Implementer would REFUSE). Patterns reusable Contract V2 audit recovery + Budget changelog UI: synthetic recovery FE merge + userMap fallback + drop misleading badges + preventive batch fix systemic gap. CICD result: 7 commits `e23f51c..506cada` push remote, runs #215 FAIL Plan M tests SQLite tie-break re-emerge → #216-#221 PASS streak. Gotcha #48 SQLite tie-break pending docs.
