ARCHITECTURE §8 (Promotion across Environments) L287 had column-
alignment drift from Pass 39's `replace_all acme-staging → acme-stg`.
The 12-char acme-staging filled the column padding; the 8-char
acme-stg shifted "1.3.0" left of the adjacent "1.4.0"/"1.2.0" values.
PERSONAS-AND-JOURNEYS L230 had the same Pass 39 fix but I'd done
that as an explicit Edit with proper padding; ARCHITECTURE used
replace_all which produced misaligned 7-space gap.
Fixed: acme-stg padded to acme-stg + 11 spaces (was 7) so all four
rows in the §8 mockup table align at the version column.
Methodology lesson #17: replace_all on shorter strings inside ASCII
code-block tables silently breaks column alignment. Greps can't
detect whitespace-alignment drift; manual column-check after
replace_all is needed.
ARCHITECTURE.md §1-§14 deep re-scan with all current lessons:
- §3 Topology: 15-component Catalyst control plane matches PTS §2
union (post-Pass 40). Per-host-cluster list omits OpenTofu
(bootstrap-only/not-runtime) defensibly.
- §5 explicitly defines <env> as {org}-{env_type} — anchors the
ws.<env>.> shorthand Pass 30 noted.
- §10 11-component bootstrap kit matches SOVEREIGN-PROVISIONING §3.
- §11 bp-catalyst-* list matches IMPLEMENTATION-STATUS §2.
- §12 Independent-failure-domains cites OpenBao per-region Raft ✓.
platform/langfuse/README.md: clean. Banner correct (§4.7 AI
Observability). Distinguishes per-host-cluster Grafana stack from
Application-level LangFuse correctly.
Drift found. Consecutive-clean count remains 0 but drift surface
shifting toward cosmetic territory (column alignment, freshness)
rather than architectural.
