⚠️ cicd-lane return-garble tracker (#53)

cicd-spawn đôi khi trả memory-curation slice ("Compressing S112/S111") thay verdict (×5/6 qua S114; cumulative ×18 all-agents → feedback_agent_return_garble_recover, root-cause = curate-at-return). Recover: em-main-solo curl-verify. S115 (#385)+S116 (#386) cicd-lane CLEAN-return no-garble ×2 — verdict delivered OK.

🚨 Recurring CI/CD bug patterns (catch priority)

• #39 act_runner github.com TCP timeout — run hang "Set up job" 21s. Log dial tcp github.com:443 i/o timeout. Fix: manual checkout bypass hardcoded .gitea/workflows/deploy.yml. KHÔNG revert.
• #40 npm cache tsc not found — build_fe_admin fail post cache: npm. DISABLED rolled back a21790d. KHÔNG re-enable.
• #41 paths-ignore docs-only skip — code commit không trigger CI? Check git diff --name-only HEAD~1 HEAD vs paths-ignore 7-entry từ D10 S111 8aa3869 (#495): ['docs/**','**/*.md','.claude/skills/**','.claude/agent-memory/**','.claude/workflows/runs/**','.gitignore','scripts/**.md']. Gitea evaluates push range — ≥1 commit có non-ignored file → toàn range build. ⚠️ AS-6 BASELINE SHIFT: từ #495, memory-push chứa memory-budget.json/agent-memory-file/run-trace HẾT trigger CI (pattern #490/#492 DEAD).
• #25 IIS WebSocket — notification-hub/negotiate 401/404 prod. Fix: WebSocket module enable web.config site api (skill iis-deploy-runbook).
• #48 SQLite tie-break — OrderByDescending(CreatedAt).First() pick wrong khi 2+ .Add() cùng frozen-clock. Fix: discriminator filter BEFORE OrderBy.
• Bundle hash unchanged = ship FAIL — push+action success nhưng prod không đổi. Verify via INDEX.HTML ref (curl -s https://admin.solutions.com.vn/ | grep -oE '/assets/index-[A-Za-z0-9_-]+\.(js|css)'), NOT by GETting a hash-named asset directly. ⚠️ verify MUST sau status=success (Run #242 false-positive: check khi "running" → stale hash).
  • 🔴 #69 (S72 #312) — FE bundle hash NON-DETERMINISTIC per rebuild. deploy.yml Remove-Item fe-*\* -Exclude web.config+Copy-Item dist\* runs UNCONDITIONALLY every run (path-filter gates whole-workflow, NOT per-step). ⟹ "BE/governance ⟹ frozen" can be FALSE; rotation possible every deploy. To detect REAL FE change, diff fe-*/src in commit/range, NOT hash-delta.
  • ⚠️ SPA-fallback 200 trap (S72): server rewrites /*→/index.html so GET /assets/index-<ANYTHING>.js returns 200 even for fake hash (control ZZdoesnotexist0.js→200, size~919b text/html). Old-hash-still-200 MEANINGLESS. RELIABLE signal = parse index.html <script src>, GET that exact path + check size_download LARGE (real ~1.6MB vs fake ~919b) + Last-Modified in deploy window + 2nd-fetch byte-stable (no mid-deploy transient).
  • 🟢 #69-REFINE (S83 #333) — hash can stay IDENTICAL across deploy when fe-*/src 0-change. #69 "rotates EVERY deploy" NOT absolute: identical Vite source ⟹ byte-identical output ⟹ same content-hash. MOST RELIABLE ship-proof = Last-Modified on real bundle IN deploy-window + real-size, NOT hash-delta (hash-delta false-NEG when src unchanged, false-POS risk per #69). 0-FE-change ⟹ hash EITHER same (#333/#485-487/#495/#385-S115) OR rotated (#312/#489) — both benign; ship-proof = fresh LM-in-window + real-size + marker.
• Migration drift prod vs repo — compare ls .../Persistence/Migrations/*.cs vs sqlcmd __EFMigrationsHistory. Fix: check Program.cs/DbInitializer app.MigrateDatabase() + app pool recycle. Mig-applied proof = __EFMigrationsHistory top==repo-HEAD; stuck-old ⟹ pool didn't recycle ⟹ FAIL even if status=success+bundle-rotated.

📋 5-stage checklist (EVERY run)

• Stage 0 RAG infra: Get-Service Qdrant Running + http://localhost:6333/healthz. Collection proj_solution_erp.
• Stage 1 Push+filter: git log -1 --format='%H %s' + git log origin/main..HEAD empty + diff vs paths-ignore (docs-only → SKIPPED-DOCS return).
• Stage 2 Gitea poll (max 10 iter × 60s): API .../actions/tasks?limit=5 (NOT /runs 404). Match head_sha (NOT run_number — cancelled runs shift numbering). ⚠️ updated_at stale ~2min (gotcha #46) → cross-check VPS mtime. Foreground-sleep BLOCKED Windows → Monitor-style busy-wait-curl-spin ~30s/iter.
• Stage 3 Test gate: baseline 495 PASS (45 Domain + 450 Infra; S116 #386 88368fd — 486+9 PE submit-guard/finalize/budget tests [PeSubmitGuardAndBypass +166L / PeCcmThresholdFinalize +118L / PeMultiWinner +72L / PeWorkItemBudget +51L]; prior 486 [S114 #384 d436af2 +9 multi-NCC / S115 #385], 477, 458, 440, 436, 434, 421). CI runs both proj BEFORE build/deploy → status=success ⟹ test gate passed (tasks terminal=status:success, conclusion NOT populated — trust success NOT log-numeric). Local grep undercounts (Theory/InlineData). Phase 9 UAT skip OK.
• Stage 4 Post-deploy (if SUCCESS): auth login bearer (admin + nv.test gotcha #44; token=accessToken route /api/auth/login) → 3-5 endpoint smoke 2XX (incl new — NEW-endpoint bodyless-POST returns 411 IIS Length-Required pre-auth NOT 404; re-probe WITH body → 401 confirms wired) → FE bundle hash 2 app (per #69 = real-size-vs-fake not hash-delta) → SignalR negotiate (gotcha #25) → EF mig prod==repo.
  • Stage 4.6 (S29 CRITICAL): sqlcmd seed sample verify post-deploy (NOT chỉ schema). Seed=runtime-row-insert (no history/tables advance) → verify via DB-query (e.g. Permissions count), NOT bundle-frozen-alone.
  • Discovery: ASP.NET 10 record enum needs numeric input unless JsonStringEnumConverter (SOL has NO converter → FE sends numeric). sqlcmd ssh Windows-auth \\\\SQLEXPRESS 4-backslash. INFRASTRUCTURE seed MUST run (NOT inside if(!demoSeedDisabled)); DEMO seed gated → gotcha #51.
• Stage 5 Report PASS/FAIL + evidence + MEMORY update.

⚠️ Anti-patterns (DO NOT)

1. ❌ Push fix code — READ only, escalate em main · 2. ❌ Speculate fail without log · 3. ❌ Skip post-deploy bundle hash (biggest catch) · 4. ❌ Skip MEMORY · 5. ❌ Poll forever (max 10 iter) · 6. ❌ Auto-rollback (escalate + recommend) · 7. ❌ Verify docs-only (SKIPPED-DOCS return ngay)

🧠 SOLUTION_ERP CI/CD essentials (S80 verified — re-ground từ docs/STATUS.md canonical)

• Gitea: git.baocaogiaoduc.vn/vietreport-admin/solution-erp · workflow .gitea/workflows/deploy.yml · paths-ignore 7-entry (D10 S111 #495): ['docs/**','**/*.md','.claude/skills/**','.claude/agent-memory/**','.claude/workflows/runs/**','.gitignore','scripts/**.md']. Anon API works (public repo) when GITEA_TOKEN absent.
• Prod: api/admin/eoffice .solutions.com.vn · SSH ssh vietreport-vps (Administrator, id_ed25519) · IIS phys paths: API C:\inetpub\solution-erp\api · admin \fe-admin · user \fe-user. DB .\SQLEXPRESS/SolutionErp/vrapp SQL-auth. Conn key = ConnectionStrings.Default (NOT DefaultConnection). DB pw = buKL3TGBkD0wDDbYVw65QeX9 (User Id=vrapp; ⚠️ Password field has NO vrapp/ prefix — S89 login-failed when prefix included; read verbatim from prod appsettings.Production.json ConnectionStrings.Default when $env:PROD_DB_PASSWORD empty). ⚠️ skill-doc path C:\inetpub\apps\SolutionErp\Api STALE.
  • SSH→PS quoting (S42): nested bash→ssh→powershell mangles $var/\" → use iconv UTF-16LE | base64 → powershell -EncodedCommand $B64; OR write ps1-file + powershell -File $(cygpath -w). sqlcmd over SSH direct -W -h -1 pw-inline. sys-catalog string-concat → COLLATE DATABASE_DEFAULT (collation conflict).
• Tests baseline: 495 PASS (45 Domain + 450 Infra · 0 fail/skip; S116 #386 88368fd; prior 486/477/458/440/436/434/421). Phase 9 UAT skip OK. 🔑 Concrete count via anon log .../actions/runs/{run_number}/jobs/0/logs (~18KB) → per-project Passed! - Failed: 0, Passed: N, Skipped: 0 (NOT just status=success; /api/v1/.../tasks/{id}/logs variant 404s — use web-UI runs path).
• Mig latest repo: Mig 65 BackfillPeQuoteIsSelectedAndWinnerInvariant (S114 d436af2; DATA-ONLY no-schema 2-dir backfill, INVARIANT Supplier.IsWinner ⟺ Any(Quote.IsSelected); Down=no-op, NO ModelSnapshot change [2 mig-file = correct data-only], SQL-Server-only [SQLite EnsureCreated skips]; VERIFIED-APPLIED-PROD history-top + violations=0 + sys.tables=89). Prev Mig 64 AddSupplierPublishState / 63 / 62 ExpandSupplierFields (see docs/CLAUDE.md migration table). Path src/Backend/SolutionErp.Infrastructure/Persistence/Migrations/. Prod check sqlcmd __EFMigrationsHistory ORDER BY MigrationId DESC. ⚠️ sys.tables(is_ms_shipped=0)=89 — AddColumn/data-only don't change count; commit touching no new table ⟹ 89 correct, don't FAIL. enum-additive = int NO-mig (history NOT-advance + empty git diff -- '*Migrations*').
• Bundle hash live: current ship-baseline = S116 #386 (admin js Dd55jBpj/css CfunQHbd · user js DVDr1UQ4/css DGqqHQXS; size 1,656,224/1,562,572b; LM 10:12:47/10:13:41 GMT 07-13) — JS-rotate/CSS-frozen from S115 (D51OYyGV/BVdssm5S). See S116 recent-run entry for markers. ⚠️ id≠run_number (head_sha-keyed). PER #69 TWO-MODE hash is SNAPSHOT-per-run NOT stable-baseline (rotate on real-src OR benign-0-src; freeze on 0-src) — ALWAYS re-snapshot LIVE post-success; ship-proof = LM-in-window + real-size (vs 919b SPA-trap) + marker-grep, NOT hash-delta. js-rotate/css-frozen = FE-logic-no-style fingerprint.
• Bearer: admin admin@solutions.com.vn/Admin@123456 (full) · UAT nv.test@solutions.com.vn/TestUser@123456 (Drafter CCM, gotcha #44 check).

🔑 Critical config (flag commit nếu tái xuất)

Node CI 20.x (feedback_node_cicd) · MediatR 12.4.1 (gotcha #1, flag Version="14) · Swashbuckle 6.9.0 (gotcha #2) · act_runner manual checkout (#39) · npm cache DISABLED (#40, flag cache: npm)

🎯 Per-NV admin opt-in wire — 10-point checklist (cumulative S22→S23)

Cross-ref feedback_per_nv_permission_scope. Per-NV/per-Level refactor MUST verify: 1 Domain field · 2 EF HasDefaultValue(false) · 3 Mig 3-file · 4 Service read · 5 Domain+App DTO mirror · 6 Designer FE checkbox · 7 AwLevelDto+ToDto · 8 CreateAwLevelInput+Update mutation · 9 Lookup discrimination (FirstOrDefault ADD ApproverUserId==actorId + admin fallback) · 10 Controller body record count == Command record count. Bug latency 2-3 days prod silent khi miss 9-10. Scan grep -n "FirstOrDefault.*Order.*==" *.cs after OR-of-N refactor.

📊 Run stats baseline

BE (test+build) ~90s · FE × 2 ~60s/app · deploy ~30s · total ~3min code / 0s docs-only. >5min → escalate. Recent runs all ~4m40-5m.
