docs(pass-53): ARCHITECTURE §8 column alignment (Pass 39 carry-over); langfuse clean

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.

But §11 and PLATFORM-TECH-STACK §3 both classify these as per-host-cluster infrastructure (not Catalyst control plane).

+### Pass 53 — ARCHITECTURE §8 column alignment (Pass 39 replace_all carry-over); langfuse clean
+
+One fix on docs/ARCHITECTURE.md; langfuse clean.
+
+Acceptance greps clean for all 9 carry-forward categories.
+
+**docs/ARCHITECTURE.md** §8 (Promotion across Environments) line 287 had column-alignment drift introduced by Pass 39's `replace_all acme-staging → acme-stg`. The original 12-char `acme-staging` filled the column padding to align with `acme-dev` (8 chars) and `acme-prod` (9 chars) at the version column. Replacing with the 8-char `acme-stg` saved 4 chars but didn't pad — so "1.3.0" shifted left compared to "1.4.0" and "1.2.0" on adjacent lines.
+
+This is a Pass 39 follow-up: the `replace_all` semantic shortened a string inside a code-block ASCII table without re-padding. PERSONAS-AND-JOURNEYS at L230 had the same Pass 39 fix but I'd done that as a single explicit Edit with proper column padding (`acme-stg           1.3.0` with 11 spaces); ARCHITECTURE used `replace_all` which produced `acme-stg       1.3.0` (7 spaces).
+
+Fixed L287: `acme-stg       ` → `acme-stg           ` (4 added spaces) so all four rows in the §8 mockup table align at the version column.
+
+**Methodology lesson #17**: when using `replace_all` on shorter-replacement-strings inside ASCII tables/code blocks, manually verify column alignment afterward. The drift is invisible to greps (no pattern catches whitespace-alignment in table cells) but visible to readers.
+
+**ARCHITECTURE.md §1-§14 deep re-scan** with all current methodology lenses applied:
+- §1 platform-in-one-paragraph: clean. Concise summary consistent with all canonical docs.
+- §2 Two scales: clean. SME/Corporate distinction matches GLOSSARY/SECURITY §6.
+- §3 Topology: 15-component Catalyst control plane list (line 62-66) matches PTS §2.1+§2.2+§2.3 union (post-Pass 40 fix). Per-host-cluster parenthetical lists 20 components — defensibly omits OpenTofu (bootstrap-only/not running at runtime) since the diagram shows what's running. PTS §3 has 21 (with opentofu); the reference "see PLATFORM-TECH-STACK §3" delegates the canonical full list. Acceptable.
+- §4 Write side: Pass 29 fix `gitea.<location-code>.<sovereign-domain>` intact (L121).
+- §5 Read side / CQRS: explicitly defines `<env> = {org}-{env_type}` (L167) — addresses Pass 30's "documented shorthand" anchoring.
+- §6 Identity and secrets: matches SECURITY.
+- §7 Surfaces (UI/Git/API/NOT-surfaces): matches GLOSSARY.
+- §8 Promotion: had the alignment fix above. EnvironmentPolicy YAML uses canonical `catalyst.openova.io/v1alpha1` ✓.
+- §9 Multi-Application linkage: Blueprint CRD example with depends — clean.
+- §10 Provisioning: 11-component bootstrap kit list matches SOVEREIGN-PROVISIONING §3 ✓.
+- §11 Catalyst-on-Catalyst: bp-catalyst-* component list matches IMPLEMENTATION-STATUS §2 ✓.
+- §12 SOTA principles: Independent-failure-domains entry cites OpenBao Raft per region ✓.
+- §13 OAM influence: clean.
+- §14 Read further: clean.
+
+**platform/langfuse/README.md**: clean. Banner correct (Application Blueprint §4.7 AI Safety/Observability, traces LLM calls in bp-cortex). Integration table consistent (LLM Gateway, Grafana complement, CNPG, NeMo Guardrails). The "Catalyst's general-purpose observability stack (Grafana/OTel) covers infrastructure; LangFuse covers the AI-specific dimensions" sentence correctly distinguishes the per-host-cluster Grafana stack from the Application-level LangFuse Blueprint.
+
+Pass 53 result: **drift found** (1 fix in ARCHITECTURE column alignment). Consecutive-clean count remains 0 (Pass 51 reset, Pass 52 had date fixes, Pass 53 has alignment fix). Convergence trajectory continues — drift is now in increasingly cosmetic territory (column alignment, freshness markers) rather than architectural.
