    v1.28 is a feature milestone (CLI Canonicalization + Identity Layer).
    Four active personas: backend-engineer (Lambda/DynamoDB/KMS/CodeArtifact),
    security-engineer (Argon2id/KMS/ABAC/threat model), cli-engineer
    (subcommand surface/mode_resolver/argparse/CAP-034), lead-developer
    (plan/review/ship/capability gate). frontend-engineer + data-engineer
    deactivated (no UI, no data pipelines). The kj-binary-in-Lambda-layer
    risk (D-227, RESEARCH §7) is the highest-risk item; P2 spike confirms.

### frontend-engineer
```yaml
active: false
phase_specific: false
reason: "No UI in v1.28 (CLI + JSON endpoints only). JWKS serves application/json; no HTML/CSS/JS surface."
```

### data-engineer
```yaml
active: false
phase_specific: false
reason: "No data pipelines / metrics / PowerBI work in v1.28. The metrics layer is v1.17-complete; v1.28 adds audit events but no new fact/dim tables."
```

## Territory overlap notes

- `core/lambda/contract_ingestor.py` (dual-use refactor, REQ-329) =
  backend-engineer territory. `core/lambda/nova_idp_auth.py` +
  `nova_idp_token_vend.py` are **co-owned** by backend-engineer (Lambda
  plumbing, DynamoDB, function URLs) + security-engineer (crypto, ABAC,
  Argon2id logic inside).
- `core/mode_resolver.py` = cli-engineer. `core/policy_engine.py` =
  security-engineer (the ABAC evaluation path).
- `nova/idp/setup.py` = cli-engineer (the subcommand + arg parsing) +
  backend-engineer (the CloudFormation generation + deploy).
- `nova/auth/*` = cli-engineer (subcommands) + security-engineer (the
  token exchange + credential storage logic).

## Phase-specific personas

None. All four active personas span the full milestone. The
security-engineer is heaviest in P2 (identity layer) + P3 (threat model);
the cli-engineer is heaviest in P1 (CLI substrate); the backend-engineer
spans P1 (CodeArtifact/layer) + P2 (Lambdas/DynamoDB).

# Personas — v1.29 Reposplit + Identity Layer Bring-Live

  note: |
    v1.29 is a feature milestone (Reposplit + Identity Layer Bring-Live).
    Pure ops/devops focus — Terraform modules are authored out-of-band in
    nova-platform-ops; CIAgent in acdel delivers publish.yml, Gitea scrub,
    CFN archive + CLI terraform-delegation, operator guide, consumer bump.
    Five active personas: backend-engineer (publish.yml ECR image, Lambda
    zip, GitHub Releases), security-engineer (kj static build verification,
    KMS round-trip tests, ABAC E2E, M1.5 gate), cli-engineer (nova idp
    setup --apply terraform delegation, CFN archive), data-engineer
    (DynamoDB import references, outbox bootstrap docs), lead-developer
    (plan/review/ship, Gitea scrub, decisions, operator guide, milestone
    wiring). frontend-engineer deactivated (no UI).

## Territory overlap notes

- `.github/workflows/publish.yml` (REQ-354) = backend-engineer (ECR
  image build, Dockerfile, Lambda zip) + lead-developer (Gitea scrub
  removes the `.gitea/workflows/publish.yml` mirror in P2, D-232).
- `nova/idp/setup.py` (REQ-369) = cli-engineer (the `--apply` delegation
  + `which terraform` detection) + backend-engineer (the CFN archive
  content — the CFN template is backend-engineer territory from v1.28).
- `platform/abac/kj-version.txt` = security-engineer (KJ-STATIC audit
  reads + verifies the SHA) + backend-engineer (publish.yml reads the
  SHA to embed in the ECR tag).
- `docs/operator-guide-platform-ops.md` (P4) = lead-developer (cutover
  gates, cost section, artifact-mirror fallback) + data-engineer (PITR
  restore, DynamoDB imports) + security-engineer (KMS rotation, JWKS
  reachability, PAT revocation).

## Phase-specific personas

None. All five active personas span the full milestone. The
backend-engineer is heaviest in P1 (publish pipeline); the
lead-developer is heaviest in P2 (Gitea scrub + decisions) + P4
(operator guide) + P6 (final ship); the cli-engineer is heaviest in P3
(CFN archive + TF delegation); the security-engineer is heaviest in P1
(M1.5 gate tests) + P4 (operator guide security sections); the
data-engineer is heaviest in P4 (operator guide data sections).
