 ## Challenges
 
-### G-Q1 — Does kyverno-json violate "platform functions without AI"?
+### G-Q1 — Is a homegrown PoA blockchain viable for a pilot, or is it reckless?
 
-**Challenge:** NORTH_STAR.md Strategic Objective #2 says "the platform
-functions without AI." kyverno-json is a new runtime dependency. Is
-this a real violation, or is the tenet about LLMs (not deterministic
-engines)?
+**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 0.95). kyverno-json is deterministic
-(same policy + payload → same result, every run). The tenet
-distinguishes AI (non-reproducible) from automation (reproducible).
-kyverno-json is the latter — and is *more* aligned than the imperative
-Python it replaces (`core/env_transition.py`, `core/regression_verify.py`)
-because the policy is declarative (visible, auditable). The
-`is_configured()` guard ensures the platform runs without the binary.
-Already resolved as D-120 in CLARIFY. No revision needed.
+**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 — Is the PolicyEngine protocol over-engineered for a 2-engine future?
+### G-Q2 — Does "all types of securities" scope-explode the milestone?
 
-**Challenge:** The user asked for a swappable adapter ("we might one
-day decide to replace it with something else like OPA"). A Python
-Protocol + registry is ~40 lines. But Nova has 1 engine today. Is this
-premature abstraction?
+**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 *explicitly* asked for
-the swap boundary — this is not speculative abstraction, it's a
-stated requirement. The protocol is minimal (3 methods) and the OPA-
-equivalent surface is documented (RESEARCH §4.2) — the swap is a known
-quantity, not a hope. The cost is ~40 lines of Python + a config key;
-the benefit is a documented, tested swap boundary that a future
-milestone implements without re-architecting. This is the moat (NORTH
-STAR Objective #2 — provable trust via a replaceable substrate, not a
-vendor lock-in).
+**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 wrapping checkov findings in kyverno-json meta-policies break the MTTR < 60s target?
+### G-Q3 — Does the consumer-repo-as-2nd-project break single-project tooling?
 
-**Challenge:** NORTH_STAR.md MTTR target: < 60s p95. Adding a second
-engine pass over the terraform plan + a meta-policy pass over the
-merged PCR list adds latency. Does this break the target?
+**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 0.88). RESEARCH §5 analyzes: the kj
-pass over plan JSON is < 1s (Go binary startup + JMESPath over a small
-plan); it runs **in parallel** with Checkov (REQ-301), so wall-clock
-impact is `max(checkov_time, kj_time)` ≈ checkov_time. Meta-policies
-run in-memory over the merged list (< 10ms). Total MTTR impact: < 1s
-on a 5-15s step. **Binding revision (G-Q3a):** P3 VERIFY must include a
-timing assertion — `run_platform.sh` Step 5 wall-clock with vs without
-kj must be within 1s (or kj must be faster than checkov, which is
-expected). Captured as a P3 verify gate, not a PLAN change.
+**Verdict:** PROCEED (confidence 0.90). `run.md` Step 0 explicitly
+specifies multi-project mode: `projects[]` with length > 0,
+`active_projects` array, `.ciagent/<slug>/` subdirectory paths, branch
+prefixes `<slug>/`. The `---ci---` block gains a `project: <slug>`
+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 — Plan revision: NullEngine fallback may mask misconfiguration
+### G-Q4 — Does the P2 contract reference a `dynamodb` module that doesn't exist until P3?
 
-**Challenge:** PLAN.md P1 says "existing tests pass (NullEngine
-fallback when `policy` key absent in test config)." But the v1.25
-config.json *sets* the `policy` key. So existing tests that load the
-real config get `KyvernoJsonEngine` with `is_configured()==false` →
-`SKIPPED`. The NullEngine fallback only triggers when the key is
-*absent*. Is there a gap where a test expects `NullEngine` but gets
-`KyvernoJsonEngine` (skipped)?
+**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 0.82). The fallback path is correct
-but the PLAN wording is ambiguous. **Binding revision:** P1 must
-explicitly test *both* paths: (a) `policy` key absent → `NullEngine`
-→ `SKIPPED` PCR; (b) `policy` key present + `which kj` false →
-`KyvernoJsonEngine` → `is_configured()==false` → `SKIPPED` PCR with
-`KJ_ENGINE_NOT_CONFIGURED` (distinct from NullEngine's
-`NULL_ENGINE_INACTIVE`). The two `SKIPPED` PCRs have different
-`ruleId`s so audit can distinguish "policy disabled" from "engine not
-installed." PLAN.md P1 verification is amended to assert both paths.
-Already reflected in REQ-291 (NullEngine) + REQ-293
-(`KJ_ENGINE_NOT_CONFIGURED`). No requirement change — PLAN wording
-clarified.
+**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 — Policy explosion: 4 targets × N rules = maintenance load
+### G-Q5 — Does live-AWS pilot break the MTTR < 60s target?
 
-**Challenge:** v1.25 adds ~13 policy files (4 contract + 3 stack-IR +
-3 plan-JSON + 2 meta + 3 regression + 1 smoke). Each is a YAML file
-with JMESPath. Is this a maintenance burden that grows unbounded?
+**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 0.80). 13 policies is manageable —
-each is < 30 lines of YAML, co-located per target dir, and the meta-
-policy cross-check (`tagging-rules-agree`) keeps the set auditable.
-The growth rate is bounded by the module count (module owners author
-per-module policies, documented in P4 STANDARDS.md). The alternative
-(imperative Python in `regression_verify.py` + `env_transition.py`) is
-*less* auditable — the policies are a net improvement. No revision.
+**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 — The tagging cross-check (D-118) is the only redundant rule — is it worth the complexity?
+### G-Q6 — Is the settlement-finality policy (REQ-315) over-engineering for a pilot?
 
-**Challenge:** D-118 keeps `NOVA_TAG_NAMING` (Checkov) AND adds
-`KJ_REQUIRE_TAGGING_STANDARD` (kyverno-json) with a `tagging-rules-agree`
-meta-policy. This is the only case where two engines evaluate the same
-concern. Is the defense-in-depth worth the complexity?
+**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 0.82). The tagging standard is the
-highest-impact rule (v1.8 D-tagging-standard, v1.10 re-verification —
-the rule that gates every resource). Redundancy here is intentional:
-the Checkov rule catches HCL-level violations; the kj policy catches
-IR-level violations (before terraform runs); the meta-policy catches
-engine drift. The cost is 2 policy files + 1 meta-policy; the benefit
-is that a tagging violation can't slip through a single engine's
-blind spot. This is the textbook defense-in-depth case. No revision.
+**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 — Can `kj scan` actually evaluate the merged PCR list as a payload?
+### G-Q7 — Is D-083 deferral defensible for a pilot with real money-like flows?
 
-**Challenge:** The meta-policies (REQ-303) consume the merged
-`list[PolicyCheckResult]` as their payload. `kj scan` expects a JSON/
-YAML *file*. Is the PCR list a valid kyverno-json payload shape?
+**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 0.85). The PCR list is a JSON array
-of objects — a valid kyverno-json payload. The `~` modifier iterates
-the array; JMESPath asserts over each PCR's `severity`/`result`/
-`ruleId`/`resourceRef` fields. The engine writes the list to a temp
-JSON file and invokes `kj scan --payload <file>`. This is verified in
-P3 `test_meta_policies.py`. No revision — but **binding note (G-Q7a):**
-the `KyvernoJsonEngine.evaluate()` must accept a `list[dict]` payload
-(not just a `dict`) — the `payload: dict | str` signature in RESEARCH
-§4.1 is too narrow. **Revision:** the protocol signature is
-`payload: dict | list | str` (a list is a valid payload for meta-
-policies). Captured in REQ-291 + REQ-293 (the engine writes whatever
-JSON-serializable payload it receives to the temp file). PLAN.md P1
-amended.
+**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 — Plan revision: the OPA swap surface claims (RESEARCH §4.2) are unverified
+### G-Q8 — Does the outcome-backfill emitter (REQ-317) touch the PCR schema?
 
-**Challenge:** RESEARCH §4.2 documents the OPA-equivalent surface
-(`opa eval -d <dir> -i <json>`), but no `OpaEngine` is implemented in
-v1.25. Is the swap-boundary claim testable, or is it aspirational?
+**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:** REVISE (confidence 0.78). The swap-boundary claim is
-*testable in v1.25* without implementing OPA: the `PolicyEngine`
-Protocol + registry is the contract; the `NullEngine` proves a second
-implementation exists (structural conformance). **Binding revision
-(G-Q8a):** P1 `test_policy_engine.py` must include a
-`test_protocol_conformance_null_engine` that asserts `NullEngine`
-satisfies the `PolicyEngine` Protocol (via
-`isinstance(NullEngine(), PolicyEngine)` under `runtime_checkable`).
-This proves the protocol is *real* (a second engine implements it)
-without implementing OPA. The OPA-equivalent surface in RESEARCH §4.2
-stays as documentation (the future milestone implements it). PLAN.md
-P1 verification amended. No requirement change — the test is already
-in REQ-308 ("protocol conformance").
+**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 — Budget: is 4 execution phases + P5 too many for the scope?
+### G-Q9 — Does the `NOVA_AWS_*` root-equivalent key create a security risk?
 
-**Challenge:** v1.25 is 19 requirements across 6 phases. Recent
-milestones: v1.24 had 15 reqs / 4 phases; v1.23 had 13 reqs / 7 phases.
-Is 6 phases too many (overhead) or too few (per-phase overload)?
+**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 0.85). 19 reqs / 6 phases ≈ 3.2 reqs/
-phase — within the v1.24 cadence (3.75 reqs/phase). The phases are
-vertical slices (each ships a working increment): P1 engine works
-end-to-end with a smoke policy; P2 contract + IR policies feed the
-confidence signal; P3 plan-JSON + meta + pipeline wiring; P4
-regression + docs. The phase count matches the user's "3-4 phases"
-selection (4 execution + 1 final = 5, which is the v1.24 shape). No
-revision.
-
-### G-Q10 — The `nova.cloudinit.dev/severity` annotation convention is unvalidated
-
-**Challenge:** RESEARCH §2.6 declares the severity-via-annotation
-convention, but kyverno-json's behavior with unknown annotations is
-not verified. Does `kj scan` ignore unknown annotations, or does it
-reject the policy?
-
-**Verdict:** PROCEED (confidence 0.80). kyverno-json is Kubernetes-
-style CRD-based — unknown `metadata.annotations` are preserved and
-ignored (standard K8s behavior). The engine reads the annotation from
-the loaded policy YAML (via `yaml.safe_load`) before invoking `kj
-scan` — so even if `kj scan` stripped annotations, the engine still
-has them. **Binding note (G-Q10a):** P1 `test_kyverno_json_engine.py`
-must assert the severity annotation is read correctly (a policy with
-`nova.cloudinit.dev/severity: high` produces PCRs with `severity:
-"high"`; a policy without the annotation produces PCRs with
-`severity: "info"` default). Captured in REQ-309 ("PCR schema
-validity" includes severity). No requirement change — the test is
-already in REQ-309.
+**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.

-- **Revisions (binding, already in PLAN/REQs):**
-  - G-Q4: P1 tests both fallback paths (NullEngine vs
-    KyvernoJsonEngine-not-configured) — distinct `ruleId`s for audit.
-  - G-Q7a: protocol signature `payload: dict | list | str` (list is a
-    valid payload for meta-policies).
-  - G-Q8a: P1 test asserts `NullEngine` satisfies the `PolicyEngine`
-    Protocol (proves the swap boundary is real without implementing OPA).
-  - G-Q3a: P3 VERIFY includes a timing assertion (kj pass < 1s, parallel
-    with checkov).
-  - G-Q10a: P1 test asserts severity annotation is read correctly.
-- **No requirement changes** — all revisions are clarifications to
-  PLAN.md verification text, already supported by existing REQs
