ship: phase-10 v1-spike-l2-and-contract-e2e (v1.1.5)

---ci---
project: acdl
phase: 10
milestone: v1.1
status: shipped
release:
  tag: v1.1.5
---/ci---

Squash merge of phase/10-v1-spike-l2-and-contract-e2e (the milestone capstone).

The end-to-end spike pipeline succeeds against real AWS:
- contracts/spike.yaml (l2-static-asset, dev) validates against the
  contract schema
- contract_resolver.py resolves it to an IR instance (validates against
  ir.schema.json)
- adapter.py compiles the IR to terraform/spike/*.tf (aws_s3_bucket)
- terraform plan -lock=false succeeds (real AWS, 1 to add)
- checkov on the TF -> 12 PolicyCheckResult records (checkov_adapter.py)
- confidence_signal.py -> score 0.8, band pass (dev >= 0.50)
- outbox_writer.py -> DynamoDB put_item (hash chain GENESIS, RPO=0)

REQ-28 verified: the adapter (adapters/terraform/) is the only
substrate-specific code; modules-ir/ + schemas/ + contracts/ +
acdl_platform/ are substrate-agnostic (the IR commitments hold, no
polyglot mess). verify_phase10.sh green.

-### 2.4 Confidence signal behavioral spot-checks (REQ-19)
-
-Run from `/tmp` with `sys.path.insert(0, '/root/acdl')`:
-
-- **Missing input → block + INPUT_MISSING:** `compute('cid','dev', inputs)`
-  with `nfrs` omitted returns `Signal(0.0, "block", {}, ["INPUT_MISSING:nfrs"])`. ✅
-- **Critical fail → 0.0 block + CRITICAL_OVERRIDE:** `compute('cid','dev', inputs)`
-  with one `severity:"critical", result:"fail"` PolicyCheckResult returns
-  `Signal(0.0, "block", per_input, ["CRITICAL_OVERRIDE:CKV_AWS_X"])`
-  regardless of other inputs. ✅
-- **Cold-start dev → pass ≥ 0.50:** `compute('cid','dev', inputs)` with
-  the ACDL_TAG_NAMING `skipped` PolicyCheckResult + all validation true
-  + neutral 0.5 for freshness/source/history/nfrs returns
-  `Signal(0.950, "pass", ...)`. ✅ (0.95 ≥ 0.50 dev threshold).
-
-Note: the `WEIGHTS` dict keys are `policy / validation / freshness /
-source / history / nfrs` (the canonical names), not the docstring's
-`policy_results` label — the docstring describes the input's *type*
-("list[PolicyCheckResult]"); the `compute()` loop iterates
-`WEIGHTS.items()` and reads `inputs.get("policy")` (the key). This is
-consistent with the Wave 4 self-verify ("`policy_results`" in the
-docstring is the descriptive label, `policy` is the dict key — verified
-at runtime).
-

-### 3.3 `platform/` package shadows stdlib `platform` — documented + worked around
+---
 
-The repo's `platform/` Python package (our code) shadows the stdlib
-`platform` module when the repo root is on `sys.path[0]` (which a
-`python3 -c` invocation from repo root triggers). `jsonschema` imports
-`uuid` → `uuid` imports `platform.system()` → fails with
-`AttributeError: module 'platform' has no attribute 'system'`.
+## Layer 3 — Security  ✅ PASS (with 1 P1 observation)
 
-`scripts/verify_phase07.sh` documents this and works around it by
-running all `jsonschema`-invoking python from `/tmp` with absolute
-paths to the schemas:
+### 3.1 Files touched in v1.1.3..v1.1.4

+✅ No secret access key pair (the 40+ char secret) appears in any Phase 09
+commit. The run script uses env-var indirection
+(`export AWS_SECRET_ACCESS_KEY="$ACDL_AWS_SECRET_ACCESS_KEY"`) — the literal
+secret is never committed.
 
-The workaround is correct: `cwd=/tmp` puts `/tmp` at `sys.path[0]`, so
-`import platform` resolves to the stdlib, not our package; the schemas
-are passed by absolute path. The verify script passes (§2.1), and my
-inline behavioral spot-checks (§2.3–2.5) reproduced the workaround by
-running from `/tmp` + `sys.path.insert(0, '/root/acdl')` to import our
-modules explicitly.
-
-**P1 — flag for post-hoc cleanup:** a v1.2 rename of `platform/` to
-`acdl_platform/` (or moving the package under a `src/` layout) would
-avoid the shadowing entirely, removing the need for the `/tmp` dance in
-every jsonschema-invoking test. This is out of Phase 07 scope (Phase 07
-must ship the `platform/` layout the README + PLAN.md committed to).
-Flagged for v1.2.

 ## Issues found
 
-### P0 (blocking) — none
+### P0 — none.
 
-No P0 issues. All must-haves from PLAN.md are satisfied; the phase gate
-`scripts/verify_phase07.sh` is green; behavioral spot-checks all pass.
+### P1 — flagged for post-hoc review (not Phase 09 failures)
 
-### P1 (post-hoc cleanup, out of Phase 07 scope)
+**P1-1 — Access key IDs in `.ciagent/VERIFY.md` (Phase 08 narrative).**
+The Phase 08 verify commit (6d27dad, which lands in the `v1.1.3..v1.1.4`
+range because it was committed after the v1.1.3 ship tag but before the
+v1.1.4 ship tag) includes the Phase 08 verify narrative at
+`.ciagent/VERIFY.md`, which references two AWS access key IDs:
+`AKIAYOZHMKZ7RK26N66W` (the rotated spike key id) and
+`AKIAYOZHMKZ772SINHFX` (the deactivated root key id). These are **access key
+IDs** (public identifiers — AWS access key IDs appear in CloudTrail logs and
+are not themselves secret), NOT secret access key pairs, so this is NOT a
+credential leak. The verify_phase09.sh Check 6 correctly scopes its AKIA
+scan to the spike deliverable dirs (`terraform/spike/ adapters/ modules-ir/`)
+and excludes `.ciagent/` narrative + the `.terraform/` provider binary.
+However, for hygiene, key IDs (even just the ID) should arguably be redacted
+from committed narrative. **Recommendation:** in a future hygiene pass,
+redact access key IDs in `.ciagent/VERIFY.md` to placeholders like
+`<rotated-spike-key-id>` / `<deactivated-root-key-id>`. This is a Phase 08
+artifact concern, not a Phase 09 deliverable concern; no Phase 09 file
+contains a key ID.
 
-- **P1-1: `platform/` package shadows stdlib `platform`.** The repo's
-  `platform/` directory is a Python package that shadows the stdlib
-  `platform` module when the repo root is on `sys.path` (any `python3 -c`
-  from repo root). This breaks `jsonschema` (which imports `uuid` →
-  `platform.system()`). `scripts/verify_phase07.sh` works around it by
-  running jsonschema-invoking python from `/tmp`, but the workaround is
-  brittle — every future test script that imports `jsonschema` (or any
-  stdlib module that transitively imports `platform`) from repo root
-  will hit the same shadow. Recommended v1.2 fix: rename `platform/` →
-  `acdl_platform/` (or adopt a `src/` layout) so the package no longer
-  collides with the stdlib name. Out of Phase 07 scope (the layout is
-  locked by Phase 06 + README + PLAN.md).
+### P2+ — none.
 
-- **P1-2: LSP false positive on `platform/confidence_signal.py:148`.**
-  The "No overloads for `get` match the provided arguments" diagnostic
-  is a pyright false positive triggered by `Dict[str, Any]` typing on
-  `pcr`. `py_compile` passes; runtime behavior is correct (verified in
-  §2.4). No fix needed in Phase 07; if a v1.2 type tightening pass
-  happens, replacing `Dict[str, Any]` with a `TypedDict` for
-  `PolicyCheckResult` would silence the LSP and improve type safety.

+# l1-s3 — S3 bucket primitive
+
+The first real L1 module for the v1.1 spike. Single-purpose,
+substrate-agnostic (the IR type is `aws:s3:bucket`, not a Terraform
+resource type).
+
+## Interface (the IR-typed contract)
+
+See `interface.json`: inputs `bucket_name` + `region` (strings), outputs
+`bucket_arn` (arn) + `bucket_name` (string), NFR `versioning` (bool,
+default true).
+
+## IR → Terraform mapping (performed by the adapter)
+
+The Terraform adapter (`adapters/terraform/adapter.py`) translates this
+L1's IR shape to Terraform:
+
+| IR | Terraform |
+|----|-----------|
+| `resource.type = aws:s3:bucket` | `resource "aws_s3_bucket" "<id>" { ... }` |
+| `resource.inputs.bucket_name` | `bucket = <value>` arg |
+| `resource.inputs.region` | `provider "aws" { region = <value> }` |
+| `resource.outputs.bucket_arn` | `output "bucket_arn" { value = aws_s3_bucket.<id>.arn }` |
+| `resource.outputs.bucket_name` | `output "bucket_name" { value = aws_s3_bucket.<id>.id }` |
+
+The adapter is a thin layer (ARCHITECTURE.md §12.2); it does not own L1
+content — it only translates.
+
+## Spike instance
+
+`spike_instance.json` is a concrete stack instance (with values
+`bucket_name=acdl-spike-bucket`, `region=us-east-1`) that validates
+against `schemas/ir.schema.json`. The adapter consumes this instance
+(not the interface contract) to emit Terraform.
+
+## Versioning (W3.D)
+
+`1.0.0` — interface MAJOR, behavior MINOR, lifecycle PATCH. MAJOR bumps
+require a new registry entry (immutable publication); old entries enter

+# l2-static-asset — thin-composition (S3 static asset)
+
+The v1.1 spike's L2. A thin-composition that references `l1-s3` only
+(depth 1). The contract's inputs (`bucket_name`, `region`) map 1:1
+through the wires to the L1's inputs.
+
+## Composition (the IR-typed thin-composition tree)
+
+See `composition.json`: `kind=l2`, `depth=1`, one child `l1-s3@1.0.0`,
+wires `{bucket_name → s3.inputs.bucket_name, region → s3.inputs.region}`
+(passthrough).
+
+## IR → Terraform mapping (D-P10-1)
+
+The Terraform adapter consumes the *resolved IR instance* (which has
+`kind=l2` + the L1 resource `s3` in its `resources` array). For a
+depth-1 thin-composition, the L2 root module **IS** the L1's resource —
+no separate `module "l1_s3" { source = "..." }` block. The existing
+adapter `TYPE_MAP` + resource emission handle both l1 and l2 instances
+(the resources array is the same shape). The `relationships` array is
+ignored at the Terraform level for the spike (composition ordering is
+implicit in the single resource).
+
+v1.2 may emit a real `module "l1_s3" { source = "..." }` block when L1s
+become published Terraform modules rather than inline resources.
