The showcase-aimock RAILWAY.md described fixtures as fetched from GitHub-raw
URLs at boot and called the Dockerfile dead code. Both are false and actively
misled debugging: fixtures are baked into the image at build time under
/fixtures/{shared,d4,d6}, the Dockerfile is the live image builder driven by
showcase_build.yml, and the d5-all.json bundle no longer exists (split into
the per-slug d6/ tree). Corrects sections 3, 4, 5, 6, 7, 8, 9 to match the
real infra, fixes the startCommand to load the three baked-in subdirectories,
and documents the account-scoped RAILWAY_TOKEN mutation path by mechanism.
Re-tier the showcase docs tree to be an agent entry point: README.md
opens with a 'when X, see Y' fanout table that routes to the right
procedural doc; each procedural doc gets a one-line tagline answering
'what does this answer'.
Consolidation:
- DELETE showcase/RUNBOOK.md — operational content merged into DEBUGGING.md
(Integration Patterns, Docker Compose Environment, Production Debugging,
Anti-Patterns, Aimock Fixture Deployment, Dev Iteration Speed). The
--isolate mechanics + CLI rules were already duplicated in DEBUGGING.md.
- DELETE showcase/QA-COVERAGE.md — per-demo coverage matrix + starter hero
matrix + probe depth + infra locations + gaps folded into TESTING.md as
the 'Per-Demo Coverage Matrix' section.
Taglines added (no behavioral change to content): TESTING.md, DEBUGGING.md,
GOTCHAS.md, INTEGRATION-CHECKLIST.md, STYLING-GUIDE.md, FRONTEND-STRATEGY.md,
RAILWAY.md, bin/README.md, aimock/README.md, aimock/RAILWAY.md,
harness/README.md, harness/docs/rotation-drill.md.
Cross-link fixups: FRONTEND-STRATEGY.md (was QA-COVERAGE.md →
TESTING.md#per-demo-coverage-matrix), TESTING.md (removed dangling RUNBOOK
companion reference), README.md (rewritten as fanout entry + retained
from-scratch setup + dashboard SOPs below the fanout).
PARITY_NOTES.md × 12 left alone (per-slug context, not redundant).

Documents the D5 e2e-deep Chromium memory envelope (4 services x 2
features = 8 concurrent contexts, ~2.4GB peak) and the two tuning
knobs operators should adjust if OOM occurs.
D5 probes hit real LLMs instead of fixtures because the 8 D5 fixture
files in showcase/ops/fixtures/d5/ were never loaded into aimock.
Railway fetches fixtures from GitHub raw URLs at boot — bundle all
D5 fixtures into d5-all.json and document the updated startCommand
with the new URL appearing before feature-parity.json for match
precedence.
