Diego asked: does the persisted ``archcenter-refs-index.json`` auto-
update when the KB is updated? Partially — mtime on the cache root
catches add/remove of subdirs (POSIX), but NOT changes to files
INSIDE existing subdirs (description.md added, .drawio replaced).
Two fixes:
1. Both KB-update tools now ``touch`` ``kb/diagram/assets/archcenter-refs``
when they finish a run that produced changes:
- ``archcenter_description_fetcher.py`` after fetched > 0
- ``archcenter_zip_downloader.py`` after downloaded / extract /
overwrite events
The touch bumps the parent mtime, which the next lookup detects
and uses to rebuild its persisted index. Closes the silent-drift
case where description.md fetches landed but the index didn't
notice.
2. ``archcenter_pattern_lookup.py --rebuild-index`` flag — escape
hatch for manual KB edits (someone replaces a cached .drawio by
hand) where neither tool ran. Removes the stale index file before
the lookup, forcing a cold rebuild.

Two persistent fixes flagged from a Codex session:
1. ``archcenter_pattern_lookup`` ran in 78 s on WSL2 because:
- ``_cached_assets`` did ``iterdir`` + recursive ``rglob`` over the
whole 113-folder cache for EVERY catalog entry (123x).
- ``_patterns_for`` reloaded ``reference-patterns.yaml`` for every
match (125 reloads = ~5 s).
- Description text from disk was read for every entry, even those
that wouldn't make the top-K.
Now: one-shot scan of the cache dir cached in-memory AND persisted
to ``kb/diagram/assets/archcenter-refs-index.json`` keyed by mtime;
patterns YAML loaded once and indexed by URL; a two-pass scoring
pipeline that only reads description text + cached_assets +
visual_patterns for the top-K candidates instead of every entry.
Result: cold run 14 s (one-time index build), warm run 1.1 s.
2. The drawio renderer had no alias for ``adb_s`` / ``adb_serverless``
/ ``autonomous_database_serverless`` / ``refreshable_clone`` —
Codex's spec used ``type: adb_s`` and the icon never resolved.
Mapped them to ``autonomous_database`` (the canonical 7-cell
stencil shipped by the OCI Toolkit), with ``adb_d`` as fallback.
Same proactive expansion in the drawio side that the PPTX side
already got (oci_goldengate, dynamic_routing_gateway, atp/adw,
kms/secret, identity/iam, iac/terraform, oac/oic, kafka).
The persisted lookup index is committed so a fresh clone hits warm
performance on first ``make diagram-lookup``.
