Move chat pipeline validation, circuit breaker execution, proxy
resolution, logging, and session header handling into dedicated
helpers to keep the SSE handler smaller and easier to verify.
Also fix shared API option precedence, rebuild skill version caches
after deletions, ignore api.trycloudflare.com false positives, and
add rate-limit manager test flush/reset hooks for deterministic
coverage.
Expand integration and unit coverage across chat routing, auth,
cloud sync, skills, executors, streaming, DB helpers, proxy handling,
and provider/model utilities.
- Combo layer: strict-random in combo.ts rotates models uniformly
- Credential layer: strict-random in auth.ts rotates connections/accounts
- Anti-repeat guarantee: last of previous cycle ≠ first of next
- Mutex serialization for concurrent request safety
- Independent decks per combo name and per provider
- allowedConnections: restrict which connections a key can use
- autoResolve: per-key toggle for ambiguous model disambiguation
- is_active: enable/disable key instantly (403 on disabled)
- accessSchedule: time-based access control (hours, days, timezone)
- Rename keys via PATCH /api/keys/:id
- Connection restriction badge in API keys table
- Auto-migration for all new columns
- Connection group field on provider connections
- Environment grouping view in Limits page (group by environment)
- Accordion UI with expand/collapse per group
- localStorage persistence for groupBy, autoRefresh, expandedGroups
- Smart default: auto-switches to environment view when groups exist
- Swap SessionsTab above RateLimitStatus
- strict-random option added to combo strategy dropdown (30 languages)
- strategyGuide.strict-random (when/avoid/example)
- pt-BR: translated all strategyRecommendations from English to Portuguese
- en: added API key management strings (accessSchedule, isActive, etc.)
- 11 tests: shuffle deck mechanics (Fisher-Yates, anti-repeat, decks)
- 6 tests: allowedConnections (schema, DB persistence, cache invalidation)
- 12 tests: API key policy (isActive, accessSchedule, autoResolve, budget)
