- aborist/qa/verify.py: three strategies tried in sequence. quote uses
sequential pairing (1st & 2nd `"`, 3rd & 4th, ...) which eliminates
the phantom inter-pair captures regex pairing produced on adjacent
quote pairs like `"title" prose "quote"`. span checks bullet/sentence
lines verbatim. entity matches multi-word proper nouns; gated by
policy ∈ {strict, hybrid, drop, proximity}. Default proximity
promotes to STRICT only when N=3 verified entities cluster within
W=300 chars in source — separates structural grounding (cast list,
infobox) from incidental mention (scattered plot summary).
- aborist/store.py: schema CHECK now `('STRICT','HYBRID','UNGROUNDED')`.
Migration helper rebuilds legacy `('STRICT','HYBRID','VISUAL')`
tables via temp-table copy, translating VISUAL → UNGROUNDED in the
SELECT. Idempotent — DDL inspection skips the rebuild on already-
migrated DBs.
- aborist/cli.py: new `aborist reclassify` re-runs the verifier
against existing live records under the current entity policy; no
LLM calls. --compare runs all four policies side-by-side, --dry-run
reports transitions without writing. Cold-source records skipped.
One providence_reclassify audit event per changed row.
- AuditMode.UNGROUNDED replaces VISUAL across search backend, FTS5,
test fixtures, CLAUDE.md. The substrate (Merkle-AGI) name was
about FOR-style visualization; in the RAG layer the semantic is
"no recoverable grounding," so the label now says that.
DEFAULT_QUERY_POLICY gains entity_policy + entity_proximity_n +
entity_proximity_window so any tuning folds into governance_policy_hash
and invalidates cache cleanly.

"""Forward migration: legacy providence_cache shards add audit_mode columns.
|
|
|
|
Regression for a defect caught on 2026-04-28: SCHEMA_SQL referenced the
|
|
new audit_mode column inside a CREATE INDEX statement. CREATE TABLE IF
|
|
NOT EXISTS skips the table on legacy DBs, so the column doesn't yet exist
|
|
when the index statement runs — the whole executescript aborts.
|
|
|
|
The fix moved CREATE INDEX idx_providence_audit into _migrate_audit_mode.
|
|
This test asserts: a DB with the pre-audit-mode schema can be opened
|
|
through connect() & emerges with all four new columns + the index.
