 | D-016 | Pages placeholder for Phase 01 is a minimal HTML stub (`<title>ACDL Evidence</title>` + "evidence stream coming soon"); full UI deferred to Phase 05 | Phase 01 success criterion is "Pages returns 200 with placeholder index.html" but Gitea has no Pages | Raw-URL HTTP 200 against `index.html` substitutes for the Pages check; full timeline UI built in Phase 05 |
 | D-017 | Each L1 `manifest.yaml` declares a single `inputs:` map of named string keys with descriptions; no nested types (substrate-agnostic, max-depth-1) | REQ-02/03 say "declared inputs"; spec forbids composition and cloud-specific types | Uniform, parseable schema that Phase 03's `mock_executor.sh` can read with python+yaml |
 | D-018 | L1 `mock_apply.sh` reads its own `manifest.yaml` for self-identification but ignores the input values (uniform stub per D-007) | D-007 mandates a literal echo + 1s sleep + exit 0; inputs are declared for traceability, not consumed | Predictable evidence events + clean separation from Phase 03 where L2s pass inputs to L1s |

+| D-019 | The 8 L1 names are fixed per REQ-02: `l1-eks-fargate`, `l1-iam-role`, `l1-lambda`, `l1-api-gateway`, `l1-eventbridge`, `l1-sqs`, `l1-s3`, `l1-cloudwatch` | REQ-02 literal | Phase 02 enumerates them exactly; no naming freedom |
+| D-020 | L2 `manifest.yaml` schema: `name`, `kind: l2`, `description`, `l1s:` (list of `{name, inputs: map}` entries). L2 references L1s by name (no path); inputs are string maps per L1 manifest declarations | REQ-04 says L2 "composes L1s"; REQ-05 caps depth at 5 (L2→L1 is depth 1) | mock_executor.sh reads `l1s:` and invokes each L1's `mock_apply.sh` |
+| D-021 | `contract.yaml` schema: `stack` (L2 name), `inputs` (string map for the L2's top-level params), optional `public-ingress: bool` (the policy violation key per REQ-07) | REQ-07 cites `public-ingress: true` as the forbidden key; REQ-08's confidence signal keys off policy pass/fail | Single flat schema drives both policy_checker and the mock_executor |
+| D-022 | `mock_executor.sh` writes `state.json` with shape `{"l2": "<name>", "l1s": [{"name":"...","applied":true,"exit_code":0}], "contract": <contract.yaml parsed>}` to the cwd; idempotent (overwrites) | REQ-06 says "writes state.json" but does not specify shape | Deterministic, parseable; Phase 05's evidence UI can include it in the audit trail |
+| D-023 | `evidence_writer.py` appends events to `audit.json` (a JSON array of event objects). Each event: `{"seq": N, "ts": <iso8601>, "stage": "dev|qa|prod|finalize", "event": "<string>", "prev_hash": "<sha256>", "hash": "<sha256 of canonical json of this event with hash field empty>"}`. The genesis event has `prev_hash: "GENESIS"` and `seq: 0` | D-005 mandates hash-chained ledger; canonical JSON for deterministic hashing | Visible tamper-evidence without overengineering; Phase 05 UI reads the array |
+| D-024 | `confidence_signal.py` reads `contract.yaml`, calls `policy_checker.py` (as a subprocess or import), returns base 0.90 on pass and 0.40 with reason code on policy failure; prints `{"score": 0.90|0.40, "reason": "<POLICY_VIOLATION:...|>"}` to stdout; exit 0 always | REQ-08 literal: base 0.90, drops to 0.40, gate ≥ 0.50 | Deterministic JSON output for the pipeline to consume |
+| D-025 | `policy_checker.py` reads `contract.yaml`, fails with exit code 1 and stdout `POLICY_VIOLATION:PUBLIC_INGRESS` if `public-ingress: true`; otherwise exits 0 with stdout `POLICY_PASS` | REQ-07 literal | Single source of policy truth; called by confidence_signal and the pipeline directly |
+| D-026 | `l3b_agent_stub.py` reads Issue body text from argv[1] (or stdin if no argv), applies the D-008 keyword map, writes a `contract.yaml` to stdout (or to `-o <path>`). Output contract uses the D-021 schema with `stack:` set to the mapped L2 name and a fixed `inputs:` map per L2 | D-008 + Act 3 example; L3B must produce the same contract format as L3A | Deterministic keyword parser; no external APIs |
