Thinkroom v0.2.4

Thinkroom v0.2.4

This maintenance release makes Prime Agent output-limit handling more robust without weakening any
transport, event, control, final-text, process-envelope, or validated-response bound.

Fixed

• Prime RPC message_update telemetry now has its own bounded event budget and no longer consumes
  the lower semantic-event budget used by research output. Unknown RPC event types remain charged to
  the semantic budget and therefore fail closed.
• Output-limit failures retain the stable public OUTPUT_LIMIT_EXCEEDED code and a bounded audit
  subtype across provider, process-isolation, engine-normalization, and failover audit seams.
• Output-limit failures during initial fork generation or its one schema-repair attempt now use the
  existing deterministic fork fallback. The run can continue to critique and synthesis without an
  extra provider retry; other provider and timeout failures retain their previous behavior.
• Managed Skills can migrate directly from the exact six-file v0.2.3 receipt to v0.2.4. Modified
  payloads and unknown, malformed, duplicate, or foreign receipt authorities still fail closed
  before mutation.

Verification

• All required lock, formatting, lint, type, and repository gates passed; the full suite contains
  309 passing tests.
• The preserved wheel was installed after 43 hash-locked dependencies with --no-deps, then passed
  locked-runtime, six-payload package, restart-readback, and exclusive-lock process checks.

The deterministic backend and fallback prove orchestration and containment, not research quality.
SQLite release support remains single-instance only.
