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.

The diagram path now follows a documented standard procedure (lookup
the closest Oracle Architecture Center reference → confirm components
→ author absolute_layout → spec validator → render → visually verify)
and ships persistent guardrails so layout regressions can't recur.
Persistent procedure changes (apply to all users, all sessions):
- tools/diagram_spec_validator.py — geometry checks (CONTAINER_TOO_THIN,
CONTAINER_PADDING_VIOLATION, LABEL_OVERFLOW_PARENT) run BEFORE either
renderer (drawio + PPTX). Catches the subnet-collapse / label-overflow
bugs that the post-render drawio validator missed.
- tools/oci_diagram_gen.py + tools/oci_pptx_diagram_gen.py — call the
spec validator before emitting any output. Adds mysql / mysql_heatwave
type aliases.
- tools/archcenter_pattern_lookup.py — scores against cached page
descriptions (not just the 1-line summary), supports --queries for
multi-fragment composition, and applies synonym expansion via
kb/architecture-center/synonyms.yaml so "LB HA cross AD" matches
"load balancer high availability availability domain".
- kb/architecture-center/synonyms.yaml — canonical synonym table
(load balancer, autonomous database, data guard, …) used by the
lookup scorer.
KB enrichment:
- tools/archcenter_description_fetcher.py + 121 cached _description.md
under kb/diagram/assets/archcenter-refs/<slug>/. Removes the runtime
dependency on docs.oracle.com when authoring specs and feeds the
pattern-lookup scorer.
- 110+ cached .drawio / .svg / .png references for offline reuse,
plus the OCI Toolkit v24.2 import (kb/diagram/assets/oci-toolkit-drawio).
Documentation:
- docs/skill/output-formats.md — new "Standard diagram-generation
procedure (MANDATORY)" + geometry rules + the new validator entry.
- SKILL.md option 2 — references the mandatory procedure.
- README.md — describes the spec validator, archcenter_pattern_lookup
and description fetcher, and updates the KB-health table.
Tooling that backs the procedure (cumulative across recent sessions):
tools/archcenter_case_runner.py, archcenter_batch_driver.py,
archcenter_zip_downloader.py, drawio_visual_validator.py,
drawio_fidelity_eval.py, harvest_drawio_icon.py, import_oci_library.py,
oci_pptx_diagram_gen.py, oci_pptx_render.py, refresh_pptx_icon_index.py.
