+`capability_instructions` and `capability_result_fields` projection. The existing
+`reward_memory_recall` readback and 2,400-character reflection limit remain.

+inserting a legacy recall readback alone cannot activate a host contribution.
+An inactive binding leaves ordinary host input, prompt and result schema intact.

+context. Capabilities cannot overwrite core authority or result fields.

+result values for outer bounds/material validation and independent attestation.
+Registered `PostSettlement` callbacks invoke the original ingest/sidecar owners
+after accountable settlement. `post_writeback` remains effect-free. Per-hook
+receipts preserve completed callbacks during partial recovery; provider receipts
+and idempotency remain with their existing owner. Unknown effects remain unknown.
+After terminal settlement, a resume leaves the journal and its original
+`post_settlement` receipt unchanged. When that receipt is uncertain, the owner
+may reconcile the same effect and return `post_settlement_recovery` as current
+readback. The owner retains the durable receipt; this projection grants no new
