Summary

PUT /api/combos/{id} with {} or with only undefined fields was a no-op that still triggered the cloud-sync path. It also made "stuck toggle" bugs invisible: the API returned 200 with the unchanged combo, the dashboard thought it succeeded, and the user had no signal.

This is a re-ship of the closed PR #4904 on the current release/v3.8.36 base.

Changes

  • Add early check after JSON parse: if no updatable field is set, return 400 with standardized envelope

Tests

  • PUT /api/combos rejects an empty body {} with 400
  • PUT /api/combos rejects a body of only undefined fields with 400
  • PUT /api/combos still accepts a single-field update (regression guard)

11/11 tests pass. All pre-commit hooks pass.

…k-aware router precedence (diegosouzapw#4973)

Dois base-reds pré-existentes que reprovavam o CI da release v3.8.36 (Fast
Quality Gates + Unit Tests fast-path), independentes de qualquer feature em voo:

1. check:db-rules / allowlist: os módulos db-internal caseMapping (diegosouzapw#4947) e
   schemaColumns (diegosouzapw#4948), extraídos de db/core.ts e importados só por ele, não
   estavam em INTENTIONALLY_INTERNAL. Registrados na allowlist (correção
   canônica — são internos legítimos, não re-exportados pelo localDb).

2. auto-strategy honra LKGP/cost (combo-routing-engine.test.ts, 2 testes): o
   task-aware reordering (diegosouzapw#4945, reorderByTaskWeight) roda para strategy "auto" e
   era aplicado DEPOIS do router explícito (selectWithStrategy: lkgp/cost),
   sobrescrevendo o orderedTargets[0] que o operador escolheu. Instrumentação
   provou: post-filter [0]=claude (LKGP) → post-task [0]=gpt-oss. Correção: quando
   o auto usa router explícito, preserva o [0] dele e deixa o task-aware refinar
   só a cauda de fallback. gpt-oss-120b PERMANECE tool-capable (não é mudança de
   catálogo; o model-capabilities-registry test segue verde).

Validado: 121 testes (combo-routing-engine + combo-task-aware + registry) verdes,
red-check confirmado, db-rules/file-size/typecheck/lint/prettier OK.

…e (FASE 2.1) (diegosouzapw#4970)

O gating de quota-share em selectQuotaShareTarget é fail-open: uma conexão
at-cap só é despriorizada, nunca bloqueada. Com 1 conexão por conta de
assinatura (caso comum), chamadas concorrentes ainda floodam a conta (→ 429 +
cooldown) — provado live na .15: 3 chamadas concorrentes com max_concurrent=1
despacharam todas em 94ms.

Adiciona um semáforo POR CONEXÃO em torno do dispatch quota-share: chamadas
excedentes esperam na fila em vez de floodar (key qsconn:<connectionId>, cap =
max_concurrent da conexão). Fail-open em fila saturada/timeout para nunca
piorar disponibilidade. Gated por strategy===quota-share + kill-switch
resilienceSettings.quotaShareConcurrencyLimit (default on; UI no ResilienceTab).

Lógica extraível isolada no leaf puro combo/quotaShareConcurrency.ts
(unit-testado: estabilidade da key, no-op sem cap, serialização real,
fail-open). Settings + schema + UI espelham comboCooldownWait.

…rrent + serialization + cooldown-wait) (diegosouzapw#4980)

Documents the v3.8.36 quota-share concurrency layers in RESILIENCE_GUIDE.md:
per-connection max_concurrent cap, the quota-share request serialization semaphore
(FASE 2.1, qsconn:<connectionId>, fail-open, kill-switch), and the combo
cooldown-aware retry — so operators know how to cap a subscription account's
concurrency and why the routing gate alone cannot contain a single-connection flood.

…vent silent model substitution (diegosouzapw#4665) (diegosouzapw#5010)

* fix(chatgpt-web): map advertised gpt-5.5/5.4-pro/5.2-pro slugs to prevent silent model substitution (diegosouzapw#4665)

MODEL_MAP was missing the advertised catalog ids gpt-5.5, gpt-5.5-pro,
gpt-5.4-pro and gpt-5.2-pro, so MODEL_MAP[model] ?? model sent the dot-form
id verbatim to the ChatGPT backend-api, which silently rejected it and served
the default Plus model. Map each to its dash-form slug. gpt-4-5 is already
dash-form and falls through correctly, so it is intentionally left unmapped.

Extends the executor MODEL_MAP test with the four ids and adds a drift guard
asserting every advertised dot-form catalog id reaches the backend in dash-form
(never verbatim), guarding future catalog<->map drift.

file-size: tests/unit/chatgpt-web.test.ts frozen baseline 2809->2855 (+46) for
the added test cases and drift-guard test; executor source unchanged in baseline.

* fix(api): stop /api/system/env/repair 500 on packaged install — lazy createRequire in sync-env.mjs (diegosouzapw#5006)

scripts/dev/sync-env.mjs ran createRequire(import.meta.url) at module
top-level. When webpack bundles it into the standalone env-repair route,
import.meta.url is frozen to the build-machine path (file:///home/runner/...)
and createRequire throws during module evaluation, so the whole route
module fails to load and every GET returns HTTP 500 — breaking the
onboarding wizard on packaged/global installs.

- Move createRequire into the guarded better-sqlite3 block (only place
  that needs it); a bad import.meta.url now returns the safe default.
- resolveRootDir() falls back to process.cwd() when fileURLToPath throws.
- route.ts passes an explicit rootDir (process.cwd()) so the helper never
  derives the root from the frozen import.meta.url, matching the .env
  target used by createEnvBackup().
- Regression guard: assert sync-env.mjs has no top-level createRequire +
  getEnvSyncPlan(oauth) works with explicit rootDir without throwing.

Thanks for this work, @KooshaPari 🙏 — closing after a maintainer review of all 46 open refactor PRs in this batch (yours included). This is not a rejection of the effort.

Why closed (applies to the whole batch): every branch here is 44–50 commits behind release/v3.8.38 and carries old versions of 500 files, so the 3-dot diff against the release reads as a **+71k/−20k rollback** rather than your actual change — merging as-is would revert ~48 already-merged commits. So none are mergeable as they stand, independent of the idea's merit.

This PR specifically: ✅ SOUND — surgical guard rejecting empty/no-op PUT /api/combos/{id} bodies with 400, with 3 tests (incl. a regression guard for legit toggles).

What happens to it: ✅ Sound — going into the "salvage" batch. We will reimplement it cleanly on top of the current release (with tests per our Rule #18), crediting you as co-author (Co-authored-by: Koosha Pari <kooshapari@gmail.com>). Reapplied together with #5094.

We ran a full case-by-case triage. The approaches worth keeping are being recorded internally with author credit, so when we pick them up the attribution travels with the code. Thank you for pushing on this. 🙌
