prompt_rule, pre_tool_rule and write_path_rule now share one settings key,
RULE_FLOOR_KEY = "kb_rule_threshold", default 0.70. The reply backstop keeps
its own 0.80, because there the floor is a stop bar. Moving the shared floor
through tune_retrieval or the Settings form records a tuning event on every
surface that reads it (set_dial, via retrieval_surfaces.sharing_floor), and
the result names the surfaces it carried as `moved_with`. Settings shows one
"Standing-rule confidence threshold" control where it showed three.
Operator ruling (2026-10-05): one shared bar for the rule arms, "especially
since we're only taking the first x number of them" -- the budget limits
what is shown; the bar only decides what is worth ranking. Kept a dial.
Why 0.70, from records read rather than percentiles:
- write_path_rule near-misses at 0.7199-0.72 were all false positives
(rule 149 against a Lidarr comment, 157 against a retention Svelte file,
121 against an Archives restore, 164 against a config test, 131 against a
Go package), so the old 0.72 was not hiding real hits -- but the band does
noise control on this arm, so dropping 0.02 costs little.
- prompt_rule: the operator set 0.70 by hand on 2026-09-18, after a 0.60
experiment admitted junk and was reverted. 0.70 is the number with a human
decision behind it.
- pre_tool_rule lines near 0.68 this session were mostly noise; rising to
0.70 trims them, and the band still narrows what clears.
Retired keys: kb_promptrule_threshold, kb_toolrule_threshold and
kb_rulehint_threshold are no longer read. Rows an install stored under them
stay in the settings table, inert. On this instance the effective bars move
pre_tool_rule 0.68 -> 0.70, write_path_rule 0.72 -> 0.70, prompt_rule stays
0.70; record_release_defaults writes those per-surface release rows on boot,
so the telemetry shift has an event to explain it.

Step 2 of the Scribe -> Grimoire rename.
- src/scribe -> src/grimoire, and every import, patch target, module path,
hypercorn entry point and `python -m grimoire.restore` with it; pyproject,
uv.lock and the frontend package are named grimoire.
- Image git.fabledsword.com/bvandeusen/fabledgrimoire; CI's Postgres service
runs as grimoire / grimoire_test.
- Compose files default the DB user, database and (prod) volume to grimoire,
each overridable from .env, so an install created as Scribe keeps its data
by setting POSTGRES_USER, POSTGRES_DB and PGDATA_VOLUME.
- Backups are written as grimoire-<ts>.tar with format grimoire-backup-tar.
Archives named scribe-* with the scribe-backup-tar manifest still restore
and are still counted at the destination (folder and S3), with tests.
- Exports, the MCP auth realm, the ASGI scope key and the persistent logger
carry the new name.
Kept on purpose: the secret-sealing key label stays "scribe.secrets.v1",
because every stored secret was derived under it.
Plugin identity (plugin name, hooks, env vars, .scribe marker, skills) is
step 3.
