Jordan Ritter 6cc1803f37 docs(showcase): consolidate + re-tier for agent navigation (README fanout entry)
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).

(cherry picked from commit 75c9d9755c9118c8abc1fa52deda2012b768cab1)

# Showcase Railway Operations
Tagline: fleet-wide auto-update config, pending service provisioning, and the
recipe for adding a new Railway service. For day-to-day promote/snapshot/pin
operations see [`./bin/README.md`](./bin/README.md). For aimock-specific
service reconstruction see [`./aimock/RAILWAY.md`](./aimock/RAILWAY.md).
## Pending Service Provisioning
One service is wired into `showcase_deploy.yml` with placeholder
`railway_id="PLACEHOLDER-CREATE-RAILWAY-SERVICE"` and needs a real Railway
service ID filled in before its first successful deploy:
- `built-in-agent` → image `showcase-built-in-agent`
Single-service Next.js app (`BuiltInAgent` runs in-process; no separate
agent server). Required env: `OPENAI_API_KEY`. Health probe at
`/api/health`.
Until the Railway service exists, the deploy job for this entry will
fail loudly on `serviceInstanceRedeploy` — that's intentional. Provision
it via the "Adding a New Railway Service" flow below, then swap the
placeholder ID in the matrix.
The matching `starter-built-in-agent` is intentionally absent: the
starter generator (`showcase/scripts/generate-starters.ts`) does not
yet support single-service packages, so the starter will be added in a
follow-up PR alongside generator support.
## Auto-Updates (Fleet-Wide)
All 41 Railway services have `source.autoUpdates.type = "minor"` with no
schedule restriction (any time, immediately). When a new GHCR `:latest`
digest is pushed, Railway auto-pulls and redeploys without manual
intervention.
CI (`showcase_deploy.yml`) still triggers an explicit `serviceInstanceRedeploy`
after each GHCR push for deterministic health-checking. The auto-update is a
safety net, not the primary deploy path.
## Adding a New Railway Service
1. **Enable auto-updates** via the GraphQL API:
```graphql
mutation {
environmentPatchCommit(
environmentId: "<env-id>"
patch: {
"services": {
"<new-service-id>": {
"source": { "autoUpdates": { "type": "minor" } }
}
}
}
commitMessage: "Enable image auto-updates"
)
}
```
Or via Dashboard: Settings > Configure Auto Updates > "Automatically
update to the latest tag" + "At any time, immediately".
2. **Add to `showcase_deploy.yml`** `ALL_SERVICES` matrix so CI builds
and pushes the GHCR image on code changes.
3. **Add to `showcase/harness/config/probes/smoke.yml`** so the service is
monitored by showcase-harness probes.
4. **Git-based services**: auto-updates only apply to image-sourced
services. Skip step 1 for git-deploy services.
## Environment IDs
- Project: `<project-id>`
- Environment: `<env-id>`
- Token: `~/.railway/config.json` -> `.user.token`
## Known Quirks
- **Polling frequency**: Railway's auto-update polling interval is
undocumented. Expect seconds to low minutes after a GHCR push.
- **API surface**: `environmentPatchCommit` is the only programmatic
way to configure auto-updates. Typed GraphQL mutations
(`ServiceSourceInput`) do not expose `autoUpdates`.
- **`source.autoUpdates.type` values**: `disabled`, `patch`, `minor`.
We use `minor` (any semver-compatible tag change, including `:latest`
digest changes).
- **`source.autoUpdates.schedule`**: array of
`{day, startHour, endHour}`. Omit entirely for "any time, immediately".
- **CI still redeploys explicitly**: `showcase_deploy.yml` calls
`serviceInstanceRedeploy` after GHCR push so the health-check step
can verify the exact deployment it triggered. Auto-updates are the
fallback, not a replacement for CI-driven deploy verification.
