docs(P04 W2): pilot-run docs (REQ-321) — adapters/README, METRICS, ARCHITECTURE §12.8, consumer onboarding

- adapters/README.md: fixed stale TYPE_MAP/INPUT_MAP refs (the adapter is a
  stateless assembler); added the blockchain-exchange consumer row + the
  Gitea adapter note (SPEC §10 Q1 — no cross-repo uses:)
- docs/METRICS.md: Post-Pilot denominators activated (AI Decision Accuracy +
  Human Escalation Frequency + the third metric now have non-zero data from
  the blkex-pilot-apply-v0.2 run)
- .ciagent/ARCHITECTURE.md §12.8: Pilot Estate (v1.26 live) — the first real
  consumer estate, the live apply, the Gitea adapter, the evidence stream
- .ciagent/nova-blockchain-exchange/README.md: consumer onboarding guide
  (deploy invocation, secrets, contract shape, verification)

 ## How to Write an Adapter

-1. Add a stack type → Terraform type mapping to `TYPE_MAP`.
-2. Add non-identity input mappings to `INPUT_MAP`.
-3. Add non-identity output mappings to `OUTPUT_MAP`.
-4. Add a specialized `_emit_resource` branch if the resource needs nested blocks (e.g. inline policies, rule sets).
+> The adapter owns **no module content**. There is no `TYPE_MAP`, no
+> `INPUT_MAP`, no `OUTPUT_MAP`, and no per-type branch logic (all deleted
+> in the v1.11 rewrite — the 918-line monolith collapsed to a ~80-line
+> assembler). Engine-specific shape lives in each L1 module's own
+> `terraform/` dir (`versions.tf`/`variables.tf`/`locals.tf`/`main.tf`/
+> `outputs.tf`); the adapter only assembles them.
+
+To extend the Terraform adapter, **do not edit the adapter** — instead:
+
+1. Add an L1 module with a real `terraform/` dir (owning its resource
+   shape, nested HCL blocks, and defaults).
+2. Register it in `modules/registry.json` under the module name with its
+   `terraform_dir` path. The adapter reads `registry.json` to find each
+   module's directory.
+3. The adapter emits `module "<rid>" { source = "<path>" }` blocks at
+   the root, with resolved inputs + wired `ref:` refs between modules.
+   No type-specific translation lives in the adapter.
+
+> If you find yourself reaching for a "TYPE_MAP"-style constant, the L1
+> module is missing a piece — fix the module, not the adapter.

+## Consumers
+
+The Terraform adapter compiles contract IR for consumer estates. The
+first real consumer estate is now live:
+
+| Consumer | Version | Environment | Account | Forge / Adapter | Status |
+| --- | --- | --- | --- | --- | --- |
+| `nova-blockchain-exchange` | v0.2 | dev | `581513795199` | inline adapter (see note below) | **live** (pilot apply `blkex-pilot-apply-v0.2`, 2026-08-19) |
+
+### Forge adapter note (SPEC §10 Q1)
+
+Forge Actions (the consumer's forge runtime) does **not** support
+cross-repo `uses:` references — the forge rejects
+`uses: <owner>/<repo>/.github/workflows/<file>@<ref>` with
+`expected format {owner}/{repo}/.{git_platform}/workflows/{filename}@{ref}`.
+The consumer (`nova-blockchain-exchange`) therefore uses an **inline
+adapter** in its `deploy.yml`: the workflow does `actions/checkout@v4`
+on the consumer, then `actions/checkout@v4` `acdl/acdl` @ `ref: v1.25`
+into `platform/`, and runs `bash platform/scripts/run_platform.sh ...`
+directly — no `uses:` indirection.
+
+The platform's own `.github/workflows/deploy.yml` (this repo) stays as
+the **GitHub Actions reference implementation** — the reusable
+`workflow_call` workflow used by GitHub-hosted consumers. The two
+files share the same contract shape; the only declared difference is
+the forge/runtime, not the stages or commands. See
+`.ciagent/ARCHITECTURE.md` §12.8 for the live pilot-estate wiring.
