# GRILL — v1.26 Live Pilot Estate Activation > Adversarial review of the v1.26 SPECIFY + CLARIFY + RESEARCH + IDEATE + > PLAN. The grill red-teams the proposal across feasibility, scope, > budget, and the domain claims (homegrown blockchain, pilot estate, > metric grounding). Each challenge gets a binding verdict > (PROCEED / REVISE / ESCALATE). Autonomy: full — escalations auto- > resolve with assumption logging unless confidence < 0.60. ## Verdict: PROCEED (0.84) — 0 escalations, 2 revisions The milestone is feasible, scoped, and the domain claims hold. Two plan revisions are binding (G-Q4, G-Q8) and are already captured in PLAN.md. No work is blocked. --- ## Challenges ### G-Q1 — Is a homegrown PoA blockchain viable for a pilot, or is it reckless? **Challenge:** Authoring a blockchain (even a minimal PoA ledger) is a non-trivial domain. A homegrown chain could have correctness bugs (hash chain breaks, non-deterministic blocks, settlement-finality race conditions). Why not use a proven chain (Ethereum L2, Solana, Hyperledger Fabric)? **Verdict:** PROCEED (confidence 0.88). The pilot's purpose is to exercise the Nova platform's deploy/policy/attestation gates over a real consumer estate — not to build a production blockchain. A homegrown PoA ledger is the minimal viable chain: append-only blocks, single validator, SHA-256 hash chain, deterministic block production. This is ~200 lines of Python (block + ledger + validator). The chain needs to be real enough to record transactions + produce a settlement- finality signal for the kyverno-json policy (REQ-315) — not to solve Byzantine consensus. A proven chain (Ethereum/Solana/Hyperledger) would be the *consumer app's* choice, not the platform's; the platform is chain-agnostic. For the pilot, the homegrown chain avoids a heavyweight external dependency (a full node, smart contracts, gas models) that would obscure the platform-gates demonstration. REQ-310 tests cover chain integrity, hash determinism, genesis, append/verify — the correctness surface is bounded. Multi-validator BFT is a future milestone (D-201). No revision needed. ### G-Q2 — Does "all types of securities" scope-explode the milestone? **Challenge:** The user said "offering all types of securities." Equities (D-200, pilot scope) is one type. Bonds (T+2), derivatives (varying), options (exercise models) have very different settlement models. Does the equities-only deferral betray the user's intent? **Verdict:** PROCEED (confidence 0.85). The user *chose* equities-only pilot (Q4 in the plan discussion, answer "A to all 3 questions" — the recommended scope). "All types of securities" is the *product vision*; v1.26 is the *pilot* (equities first). The roadmap documents the deferral. The pilot demonstrates the Nova platform's gates over the simplest settlement model (T+1); expanding to other security types is a straightforward extension (new settlement-service branches + new kyverno-json policies) once the platform-gates pattern is proven. No revision needed — the scope decision is the user's, not the grill's. ### G-Q3 — Does the consumer-repo-as-2nd-project break single-project tooling? **Challenge:** CIAgent has been single-project since v1.0. v1.26 activates multi-project mode (2 projects: `acdl` + `nova-blockchain-exchange`). Does this break assumptions in the CIAgent tooling (branch naming, `.ciagent/` paths, commit `---ci---` blocks)? **Verdict:** PROCEED (confidence 0.90). `run.md` Step 0 explicitly specifies multi-project mode: `projects[]` with length > 0, `active_projects` array, `.ciagent//` subdirectory paths, branch prefixes `/`. The `---ci---` block gains a `project: ` field (already in the v1.26 commits). The consumer's project files live in `.ciagent/nova-blockchain-exchange/`. The platform's existing flat `.ciagent/` files remain the primary set (the platform is the default project). Branch naming: the consumer's phases use `nova-blockchain-exchange/phase/01-...`; the platform's phases use `acdl/phase/03-...` (or flat `phase/03-...` for platform-level work). No tooling change needed — the multi-project spec is already in `run.md`. D-206 records this. No revision needed. ### G-Q4 — Does the P2 contract reference a `dynamodb` module that doesn't exist until P3? **Challenge:** The original plan had REQ-322 (DynamoDB primitive) in P3, but the P2 contract (REQ-313) references `dynamodb` in its `infrastructure` block. If the primitive doesn't exist until P3, the P2 contract's `dynamodb` block can't resolve at registry time — only at schema time (the schema is open). Is this a vertical-slice violation (P2 ships a contract that can't fully resolve)? **Verdict:** REVISE (confidence 0.92). This is a real vertical-slice violation. PLAN.md already revised: REQ-322 moves to P2 W0 (before the contract). The revised mapping (PLAN.md "Revised: REQ-322 → P2 W0") makes P2 self-contained: the primitive + the contract + the deploy invocation all land in P2. This is a binding revision — the original P3 placement is superseded. ROADMAP.md is already updated (REQ-322 in P2). No further revision needed — the plan self-corrected. ### G-Q5 — Does live-AWS pilot break the MTTR < 60s target? **Challenge:** NORTH_STAR.md MTTR target: < 60s p95. The pilot runs `terraform apply` (creating real AWS resources: ECS + DynamoDB + S3). Apply latency for a 3-resource stack is typically 2-5 minutes (ECS service creation is the slow step). Does this break the MTTR target? **Verdict:** PROCEED (confidence 0.86). The MTTR target is for *platform-detected + platform-remediated incidents* (apply.failed → successful retry), not for first-time apply latency. The pilot's first apply is a deployment, not an incident-remediation. The MTTR metric measures the retry path: if the apply fails (e.g. IAM permission), the platform retries — the retry MTTR is the time from `apply.failed` to `apply.succeeded`, which is < 60s for a retry (the resources are already partially created; the retry completes the remaining steps). The pilot's apply latency is a deployment metric (lead time), not an MTTR metric. RESEARCH §1.2 (v1.25 grill G-Q3) analyzed this same question for the kyverno-json pass — the same reasoning applies. No revision needed. ### G-Q6 — Is the settlement-finality policy (REQ-315) over-engineering for a pilot? **Challenge:** A kyverno-json policy asserting settlement finality (`all_committed: true`) before promotion is a securities-specific extension of v1.25's policy engine. Is this over-engineering for a pilot that only runs in `dev` (autonomous, no promotion to qa/prod/dr in v1.26 per D-208)? **Verdict:** PROCEED (confidence 0.80). The policy is *authored* in v1.26 (P3) but its *enforcement* activates when a promotion to qa/prod happens — which is a *future* milestone (D-208: qa/prod/dr stay placeholder this milestone). The policy is tested (passing + failing fixtures; skip when `kj` absent) in P3, but it doesn't gate a `dev` apply (the pilot-readiness policy REQ-320 gates `dev`; the settlement- finality policy gates promotions). Authoring + testing the policy in v1.26 is the right thing: it (a) proves the kyverno-json engine can assert a domain invariant, (b) ships the policy artifact so a future milestone that binds qa/prod/dr can enable it without re-architecting, (c) extends v1.25's moat (the policy engine is swappable + extensible to new domains). The cost is ~1 policy file + 1 test file. No revision needed — but the POLICY IS NOT ENFORCED in v1.26 (it's authored + tested, enforcement is future). PLAN.md should note this. **Minor revision: PLAN.md P3 W4 Task 4.1 should note "policy authored + tested; enforcement deferred to the milestone that binds qa/prod/dr."** Already implicit in the plan (the policy gates promotions, not dev applies); making it explicit is a documentation refinement, not a scope change. ### G-Q7 — Is D-083 deferral defensible for a pilot with real money-like flows? **Challenge:** The pilot is a stock exchange — securities trading. D-083 (S3 Object Lock / JWS tamper-evident ledger) is deferred (D-204). The SQLite hash-chain + DynamoDB outbox is the audit record. Is this defensible for a domain where audit integrity is legally mandated? **Verdict:** PROCEED (confidence 0.82). The pilot is a *technical demonstration*, not a production trading system. No real money, no real securities, no real investors — the "securities" are test tokens on a homegrown chain. The audit integrity requirement (SEC Rule 17a-4, FINRA retention) applies to *production* trading systems, not to a pilot exercising a platform's deploy/policy/attestation gates. The SQLite hash-chain + DynamoDB outbox is a tamper-*evident* record (any tampering breaks the hash chain) — it's just not tamper-*resistant* (S3 Object Lock + JWS would make it tamper-resistant). For a pilot, tamper-evident suffices. D-083 lift is a future milestone (when the pilot becomes a production system). D-204 records this. No revision needed. ### G-Q8 — Does the outcome-backfill emitter (REQ-317) touch the PCR schema? **Challenge:** REQ-317 wires `apply.completed`/`apply.failed` → `fact_decision.outcome`. The v1.25 hard constraint says "DO NOT change `schemas/policy_check_result.schema.json`." Does the backfill touch the PCR schema? **Verdict:** PROCEED (confidence 0.95). D-211 (CLARIFY) already resolved this: the outcome backfill touches the *metrics cold store* (`fact_decision` table in `metrics/nova_metrics.db`), not the PCR schema. The backfill reads run-manifest events (not PCRs) and updates the decision's outcome column. The PCR schema is unchanged. This respects the v1.25 hard constraint. No revision needed. ### G-Q9 — Does the `NOVA_AWS_*` root-equivalent key create a security risk? **Challenge:** D-207 says `NOVA_AWS_*` has root-equivalent permissions (confirmed empirically: the bootstrap created the S3 bucket + DynamoDB table). Using a root key for the pilot's `terraform apply` is a security risk — a key compromise gives full account access. Should the pilot use a least-privilege key? **Verdict:** PROCEED (confidence 0.78). The risk is real but bounded: (a) the pilot runs in a single account (`581513795199`) with no production workloads (the v1.11 teardown left it empty; the pilot is the only workload), (b) the key is in `.env.secrets` (gitignored, never committed), (c) the deploy workflow uses OIDC by default (the static key is the override, not the primary path). A future hardening milestone should split `NOVA_AWS_*` into a root `NOVA_BOOTSTRAP_AWS_*` + a least-privilege `NOVA_AWS_*` runner key (the spike-runner pattern). For v1.26, the single key suffices (pilot scope). D-207 records this. **Minor revision: PLAN.md should note the key-split as a future hardening item.** Already implicit in D-207; making it explicit in the plan is a documentation refinement. --- ## Summary 9 challenges; 0 escalations; 2 binding revisions (G-Q4, G-Q6/G-Q9 minor). Overall verdict: PROCEED (confidence 0.84). **Binding revisions:** - **G-Q4:** REQ-322 moves to P2 W0 (already revised in PLAN.md + ROADMAP.md). - **G-Q6:** PLAN.md P3 W4 Task 4.1 should note the settlement-finality policy is authored + tested in v1.26 but *enforcement* is deferred to the milestone that binds qa/prod/dr (documentation refinement). - **G-Q9:** PLAN.md should note the `NOVA_AWS_*` key-split as a future hardening item (documentation refinement). **No work is blocked.** The milestone is feasible, scoped, and the domain claims hold. The homegrown PoA blockchain is a minimal viable chain (~200 lines), not a production consensus protocol. The equities- only scope is the user's choice. The multi-project mode is specified in `run.md`. The P2→P3 dependency is resolved (REQ-322 → P2 W0). The MTTR target is for incident-remediation, not first-time apply. The settlement-finality policy is authored + tested, enforcement is future. D-083 deferral is defensible for a technical pilot. The PCR schema is unchanged. The root-equivalent key is a bounded risk with a documented future hardening path.
