Promotion-aware memory
Memory is not a raw log store. ContextOS treats it as a promotion pipeline: capture is immutable, candidates pass through a review queue, only promoted records are eligible for compilation. Tiered (working / episodic / semantic / durable) with consent gating and contradiction handling.
Run evidence becomes candidates first, then passes consent, contradiction, and review checks before promoted memory can be compiled into future context.
- 01Capture
Append tool results, decisions, and effects.
- 02Extract candidate
Create typed memory proposals with evidence refs.
- 03Review gate
Check consent, contradictions, and review policy.
- 04Promote tier
Route approved memory to working, episodic, semantic, or durable stores.
- 05Compile
Only promoted memory can return in a future ContextPack.
Capture → Promoted
Every tool result and decision is captured immutably; a consolidator extracts typed candidates that enter the review queue with consent and contradiction checks before promotion.
Anti-pattern prevented
PII leakage and contradiction drift: consent is checked at the candidate stage; contradictions produce typed events instead of silent overwrites.
Metrics that matter
Recall precision, PII write-back violation rate, contradiction resolution time, correction adoption rate, review-queue throughput.
Memory write proposal
Promotion is governed by class. Each candidate emits a typed write proposal that lands in the review queue with consent + contradiction checks, then routes to the tier declared by the pack's memory policy.
