v0.3.53

Session Housekeeping

• Configurable idle TTL — session idle timeout increased from 2min to 10min, configurable via sessionIdleTtlMs in config YAML
• Graceful drain on shutdown — session connections are synchronously drained on daemon stop/reload
• Session visibility — /api/sessions now returns per-session stats (id, providers, idle time, last activity)
• Bug fix — evict() now properly cleans up empty session entries from the pool

Files changed

• src/session-pool.ts — configurable TTL, getStats() method, evict cleanup fix
• src/config.ts — sessionIdleTtlMs config field (Zod schema)
• src/types.ts — ServerConfig interface update
• src/server.ts — wire config to pool, enrich /api/sessions endpoint
• src/index.ts — drain session pool on shutdown
• tests/session-pool.test.ts — 8 new unit tests

v0.3.46

What's Changed

Resilience Features

• feat(resilience): adaptive TTFB, escalating cooldown, and global backoff (#135)
  • Health-score-based TTFB: compose with latency-based via min() so unhealthy providers fail fast
  • Escalating circuit breaker cooldown: double cooldown per flap cycle (cap 60s), reset after 5 consecutive successes
  • Global backoff: return 503 immediately when all providers have health score < 0.5

Bug Fixes

• fix(proxy): use .end() instead of .write()+.destroy() in stall handler — fixes Node 22 hang
• fix(test): increase sample count in flaky selectByWeight health blending test
• fix(test): increase timeout for stall detection test to prevent CI flakes

v0.3.40

What's Changed (v0.3.38 → v0.3.40)

Bug Fixes

• Suppress "socket closed unexpectedly" — Fixed undici's socket close warning leaking to clients during hedge cancellation and stall abort. Unpipe upstream before ending passThrough, consume _intentionalClose flag in error handler, added logging for intentional aborts. (#118, #119)
• StreamState race conditions — Replaced setInterval stall poll with one-shot setTimeout. Added _stallFired guard. Terminal state guards in all setImmediate blocks. (#100, #116)
• actualModel ReferenceError — Eliminated redundant parameter to prevent ReferenceError on certain request paths. (#111, #117)
• undici socket race — Prevented undici socket race condition in hedge/stall stream destruction by unpipe-before-destroy pattern. (#114)
• GUI duplicated recent requests — Fixed conflicting provider stats and duplicated entries in provider section. (#106, #110)
• GUI error breakdown — Wire per-provider error counts (502/429) through WebSocket provider_health messages for visibility. (#103, #115)
• SSE error event ordering — Write SSE error payload before setting stream error state, ensuring client always receives the error text. (#98)

New Features

• Wizard hedging config — Added hedging config screen (concurrentLimit, windowSeconds, stallTimeout, poolSize) to wizard init. (#95, #96)
• Provider error display — Show 502/429 errors per provider in the GUI provider section. (#103)

Full Changelog: v0.3.38...v0.3.40

v0.3.38

What's Changed (v0.3.36 → v0.3.38)

New Features

• Config file location choice — Wizard init now supports project-level ./modelweaver.yaml with routing-only overlays. Auto-detects existing configs and offers menu choice. Added --global/--path flags to init subcommand. Config loading merges project modelRouting over global config. (#94)

Bug Fixes

• Stream state machine race conditions (#98, #99) — Replaced setInterval stall poll with one-shot setTimeout. Added _stallFired guard to prevent handleStall re-entry. nextState() now rejects invalid transitions instead of allowing them. Terminal state guards in all setImmediate blocks in server.ts and data handler.
• Daemon log-analysis bugs (#82) — Fixed circuit-breaker test assertions for 401 counting. Fixed hot-reload test to await async setConfig.
• 4 verified daemon issues (#93) — Fixed agent leaks on config errors and hot-reload races. Optimized metrics prune with incremental min-key tracking. Resolved spurious start→start and streaming→streaming state warnings. Fixed cache clearing order during config swap.
• GUI progress bar stall — Fixed dismissal with CSS transitionend + fallback. Added complete/error WebSocket events for timeout and error paths. Removed MAX_VISIBLE_BARS cap.
• GUI recent requests — Sort by timestamp (newest first).
