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.

Service Tiering slide no longer falls back to the workload `name`
field for the tier label, which previously rendered "Bronze Bronze"
when the spec only carried tier names. Uptime/RTO/RPO now fill from
tier defaults when the spec omits them.
Architecture Principles slide enriches caller-supplied items with
name + summary from the KB when only the principle id is given,
instead of rendering bare placeholders like "P-01 P-02".
Architecture Overview slide auto-builds a two-region visual when the
proposal spec names a `dr_region` but doesn't pre-render `architecture.visual`,
so DR is no longer dropped from the deck.
Diagram generator gained a region-level `local_dr` flag that adds a
"Local DR Standby" dormant node inside the region, and now auto-wires
an "RPC (Remote Peering)" edge between DRGs when the spec defines
two or more regions with DRGs but no manual peering connection.

Architecture Overview slide was rendering the DR region with a fallback
label (e.g. "DR STANDBY" with no region name) because _adapt_flat_spec()
only consulted disaster_recovery / architecture.dr — it never looked at
the dr_region / tenancy.regions fields the MCP actually emits. The
adapter now discovers the primary and DR regions from:
- spec.primary_region / spec.region / architecture.primary_region
- spec.dr_region / spec.secondary_region / architecture.dr_region
- tenancy.regions[] entries (strings or {region, role} dicts, with role
in {primary, hub, prod, production} vs {dr, standby, secondary,
failover})
When both regions are known, the adapter emits an architecture.visual
with two labeled region blocks so the DR region renders with its real
name (e.g. "mx-monterrey-1 [DR STANDBY]") instead of the placeholder.
If the spec already supplies architecture.visual or diagram_path, those
are preserved instead of overwritten.
Operational RACI slide kept being skipped for payloads that passed
operational_raci in a non-canonical shape. The from_spec handler now
accepts:
- Top-level key aliases: operational_raci, raci, operations_raci
- Bare string ("fully_managed") → loads KB defaults for that model
- List of dicts → used directly as raci_items
- Dict with raci_items / items / activities and model / engagement_model
- Empty raci_items → falls back to KB defaults by model
The flat adapter also now respects a user-supplied operational_raci
instead of overwriting it with the co_managed default. Verified:
operational_raci: "fully_managed" renders the Fully-Managed RACI table
with 18 activities; bare flat MCP payload still gets the 13-activity
co_managed default.

Regression after the closing-slide removal surfaced a separate bug:
_adapt_flat_spec() only emitted metadata + summary + cost, so decks
generated from the MCP flat payload collapsed to 3-5 slides of title +
summary. The deck generator's ECAL sections (service_tiering,
architecture_principles, environment_catalogue, operational_raci, etc.)
all check top-level spec keys the adapter never produced.
Adapter now also emits, from the flat payload + kb/patterns defaults:
- service_tiering from services[] (preserves any tier/uptime/rto/rpo)
- architecture / architecture_principles (ECAL "always" picks)
- ha_dr tiers derived from the distinct service tiers present
- security baseline (IAM/network/database/monitoring controls)
- environment_catalogue (Prod/Pre-Prod/Dev-Test, +DR if enabled)
- operational_raci co_managed default from the KB
- next_steps skeleton
Flat MCP payload now renders 11 content slides instead of 3-5, and the
proposal-spec.yaml path (non-flat) is unchanged — still 16 slides for
examples/proposal-spec.yaml.
Also documents the new data_services SKUs in docs/bom-cookbook.md as
Recipe 4 (BDS/DS/DF) so MCP payloads can use the catalog codes directly.

- oci_deck_gen / oci_bizcase_gen: stop appending the Thank You + Oracle
logo-only closing slides at the end of every generated deck.
- oci_bizcase_gen: Business Drivers now reads primary_driver at the
drivers-level and at the top level, and renders natural-language values
verbatim (only snake_case enum tokens are Title-cased). A spec-provided
drivers.items / additional / secondary list replaces the hardcoded
"Financial Impact of Inaction" + "Operational Impact" fallback cards.
- oci-sku-catalog.yaml: add data_services category with the four real
Big Data Service SKUs (B91128/B91129/B91130/B93555) plus EST-DS-NOTEBOOK,
EST-DS-MODEL, EST-DF-SPARK as estimate placeholders (OCI Data Science /
Data Flow have no dedicated SKUs in the public pricing API — they are
billed via the underlying compute shape).
- oci_bom_gen: resolver now prints a stderr warning and tags estimate/
unknown line items with an explicit note; the xlsx writer renders
"other" category items under an "Uncategorized — confirm SKUs" section
at the end instead of silently dropping them.

Harden bizcase, bom, deck, and diagram generators to tolerate payload
shape variants (metadata/cover/summary/line_item aliases, current_state
as string, alternate pillar keys) so MCP and CLI flat specs render
consistently. Add input-alias tests per generator.
Also loosen KB governance tests to handle multi-document service YAMLs
with optional changelogs, untrack the customer demo output under
examples/output-demo-pharma-mx/ (matches .gitignore), and ship an
ADB-S vs Aurora 500GB sample deck.

generate_deck on the MCP server passes a flat spec (customer_name, title,
workload_type, services, cost_summary, ...) — but from_spec only understood
the proposal-spec YAML shape (metadata/summary/architecture/...). With no
matching keys, only the title and closing layouts rendered, both populated
with empty strings, producing a deck that looked blank.
Detect the flat shape in from_spec and adapt it into the proposal-spec
fields that the existing slide builders already consume. Title, summary
(target state + current-state bullets) and cost slides now render from
whatever the MCP tool sends; the richer proposal-spec path is untouched.
