From db0f34f4d246e95fc92e9ccdaf31891f53e89312 Mon Sep 17 00:00:00 2001 From: Shay Date: Sun, 24 May 2026 20:30:03 -0700 Subject: [PATCH] fix(W-016): wire vault probe into ChatRuntime discovery contemplation (#257) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the gap identified in the L8 audit (PR #250): the four-tier memory model (ADR-0055) designates T1 (session vault) as a source for contemplation evidence, but _emit_discovery_candidates was calling contemplate(c) with no vault_probe, so inline contemplation operated on pack + reviewed corpus only. Changes: - core/config.py: add RuntimeConfig.vault_probe_discoveries (default False) — opt-in flag that enables the vault probe; default-off preserves all pre-W-016 discovery output byte-identically. - chat/runtime.py: add _build_vault_probe(vault, vocab) module helper that closes over the live session vault and returns a _VaultProbe callable querying at EpistemicStatus.COHERENT (ADR-0021 §3 — only reviewed-coherent entries contribute evidence; SPECULATIVE/CONTESTED/ FALSIFIED entries are excluded by vault.recall min_status filter). _emit_discovery_candidates now passes the probe to contemplate() when vault_probe_discoveries is True. - tests/test_discovery_contemplation_vault_probe.py: four contracts pinned — probe not called by default, probe called when flag on, probe evidence reachable in emitted JSONL, raising probe does not crash the loop (defensive: vault unavailability must not block discovery). Lane SHAs: 7/7 unchanged (demo_composition, public_demo, et al). Smoke suite: 67/67. Teaching suite: 17/17. New test: 4/4. Out of scope: W-017 (automated T1/T2 → T3 promotion) is a separate ratchet entry.
