Limits & defaults

Every default and cap in one table: manifest field defaults, operator env-var defaults, hardcoded model defaults, and behavioural constants.

Context — Every default value and cap in one place, introspected from runtime version 0.8.14 (manifest schema 6.1.5). Field semantics live on the concept pages; this is the lookup table.

Hardcoded model defaults

Slot	Default
Chat (llms.default absent)	interactive/agent
Evaluation (llms.evaluation absent)	interactive/google/gemini-3-flash-preview
Evaluation fallback (llms.evaluation_fallback absent)	interactive/google/gemini-3.1-pro-preview

Behavioural constants

Constant	Value	Meaning
HTTP port	8080	Container listen port.
Evaluation retry attempts	3 + 3	Per internal decision call: 3 on the primary evaluation model, then 3 on the fallback. See Models.
Autonomous timeout default / cap	120s / 600s	Routine timeout_seconds falls back to the default and is clamped to the cap.
Callback delivery attempts	5	Autonomous callbacks / event webhooks, with backoff.
Knowledge-base query timeout	30s	Internal cap on pgvector searches (retrieval soft-fails past it).
Startup failure exit window	10s	Boot errors exit the process non-zero within this window.
