Proposal

Reconciliation consumes a bounded pack keyed by the issue and its referenced entities — never the whole estate (docs/handoff.md §Reconciliation contract step 3, §Semantic retrieval budgets).

Design

HydraMem retrieval order: entity lookup → graph neighborhood → exact/BM25 → Datalog selection; semantic ranking only as a bounded, optional fifth step. Every budget from crates/currycomb-schema Budgets applies.

Tasks

  • pack query keyed by issue identity + entities, budgets enforced
  • every returned fact carries provenance and the generation watermark

Requirement scenario

GIVEN a fixture corpus over two projection generations, WHEN a pack is queried, THEN results never exceed the declared budgets and carry the watermark of the generation that answered.

Specification-completion clause (OD-7 / #40)

The consumption policy for a stale watermark — render now, or defer effects until the requested revision is projected — awaits OD-7. This unit ships the watermark as data; it does not rule on it.
