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.

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.

6 improvements based on Oracle Architecture Center reference diagrams:
1. Edge label offset — labels pushed 15px away from edge midpoint via
mxGeometry offset injection, prevents overlap with icons
2. Auto-sizing containers — regions, VCNs, tenancy calculate dimensions
from content instead of using fixed sizes (DR region: 540→260px)
3. jettySize=auto on all edges — clean stubs leaving/entering shapes
4. Dual connection merging — duplicate from/to pairs merged into single
edge with combined label (e.g., dual FastConnect)
5. DRG placed OUTSIDE VCN, INSIDE region — matches Oracle ref arch
pattern where DRG is the central hub between external and VCN
6. container=1;collapsible=0 injected into container XML styles

Root cause: elbow=vertical conflicted with orthogonalEdgeStyle + port
constraints, causing arrows to route backwards and cross content.
Changes to oci_diagram_gen.py (generic, all diagrams):
- Remove elbow=vertical from edge base style
- Use edgeStyle=orthogonalEdgeStyle explicitly in extra_style
- Add jumpStyle=arc;jumpSize=8 — crossing edges show arc, not overlap
- Remove drawpyo waypoints="orthogonal" (now controlled via extra_style
to avoid style merging conflicts)
- Vertical edges with labels: align=left so text doesn't overlap icons
- Regression tested with PharmaCorp (dual-region) and MELI (single-region)

Edges now auto-detect exit/entry ports based on relative positions of
source and target services. Uses absolute coordinates from the layout
engine to determine whether connections should exit right→left,
top→bottom, etc.
- exitX/exitY/entryX/entryY added to every edge style
- 1.5x threshold favors vertical routing over horizontal when positions
are diagonal — matches Oracle ref arch top-down subnet flow
- Eliminates crossing arrows in multi-subnet, multi-region diagrams
- Verified with both PharmaCorp (dual-region) and MELI (single-region)
Generic code fix — applies to all diagrams, not just this spec.

oci_diagram_gen.py auto-layout improvements:
- Gateways now placed FIRST, vertically centered on VCN left edge
- Subnets offset RIGHT by gateway lane width to avoid overlap
- Gateway lane width auto-calculated from widest gateway + padding
- Network edges: teal color, thicker (2px) for visual hierarchy
- Internal edges: gray dashed for management connections
- Data edges: solid charcoal (unchanged, default)
These are generic code fixes — apply to any diagram spec, not just
the PharmaCorp demo. Verified with both PharmaCorp and MELI specs.
Also regenerated all PharmaCorp deliverables with prior fixes:
- Business case: PharmaCorp (was MELI), correct TCO/ROI/value schema
- BOM: verified SKUs from catalog, 45% global discount applied
- PDF: environment catalogue with new schema
- Diagram: clean layout with gateway offset
