fix(audit): post-v0.12 audit remediation — checkpoint typo + report template + ARCHITECTURE drift

---ci---
project: orca
phase: 28
milestone: v0.12
status: complete
---

Post-milestone audit (v0.11.28 milestone release) found 3 issues; this
commit remediates all three and tags the result v0.11.29 per the
feature-milestone progressive-patch rule (v0.11.x patch line; no
separate v0.12.0 tag per ROADMAP).

1. CHECKPOINT.json typo: key "phases_shiped" -> "phases_shipped"
   (missing 'p' made the 29-phase shipped list unreachable). All 29
   phases P0..P28 now readable by canonical key.

2. Missing audit artifact: opencode/ci/references/report-template.md
   created. Binding template covering all 5 audit steps + verdict
   convention (PASS/WARN/FAIL). Satisfies audit Step 5 check #4
   (report-template exists).

3. ARCHITECTURE.md drift: removed stale internal/orch/ reference
   (package never existed; replaced by internal/sshpush/ in v0.9).
   Appended "v0.9-v0.12 Component Addendum" documenting all 25 packages
   introduced across v0.9-v0.12 (workload/runtime, state/persistence,
   transport/bootstrap, security/identity layers). ARCHITECTURE.md now
   matches actual code structure.

Re-audit PASS: all 6 audit checks green; project state fully
reconstructable from git log.

+## v0.9–v0.12 Component Addendum (post-rearchitecture packages)
+
+The v0.9 re-architecture introduced the SSH-push model and split the
+monolithic v0.8 transport layer into focused packages. The following
+packages were added or substantially expanded across v0.9–v0.12 and are
+part of the canonical component graph:
+
+### Workload & runtime layer
+- `internal/runtime/` — runtime abstraction (process/podman/wasm/pve-vm/pve-ct), 5 backends (REQ-078, C-01)
+- `internal/scheduler/` — CLI-side scheduler, CEL constraints, affinity (REQ-083)
+- `internal/jobspec/` — job specification parsing & validation
+- `internal/spec/` — update stanza + lifecycle hooks
+- `internal/engine/` — dispatcher, executor, peer, registry, audit, scheduler
+
+### State & persistence layer
+- `internal/model/` — core data model (Node, Job, Task, Certificate, Alloc)
+- `internal/store/` — cluster-state store, per-namespace modernc/sqlite
+- `internal/paths/` — path resolution for the multi-namespace layout (R-002)
+- `internal/certpaths/` — certificate path helpers (known_hosts, CA material)
+- `internal/cache/` — CLI-side orca_cache SQLite (R-008)
+- `internal/migration/` — v0.8→v1.0 data migration (REQ-066, C-07)
+- `internal/txn/` — transactional plane, apply-path allowlist (REQ-075, REQ-079)
+- `internal/ns/` — namespace subcommands, inheritance, constraints (REQ-068)
+
+### Transport & bootstrap layer
+- `internal/sshpush/` — v0.9 SSH-push transport, fanout, idempotency (R-001, C-18)
+- `internal/cluster/` — lead rules, rotate-lead, mixed-version tolerance
+- `internal/proxmox/` — Proxmox API + host-key TOFU (D-035)
+- `internal/stepca/` — step-ca integration (REQ-076)
+- `internal/storage/` — Syncthing storage replication + conflict resolution (REQ-081)
+- `internal/backup/` — backup/restore, signed tarball (HMAC-SHA256)
+- `internal/secrets/` — per-namespace AES-256-GCM + HKDF-SHA256 (REQ-080)
+- `internal/emit/` — emit contract (systemd units, Traefik YAML, sudoers, syncthing)
+- `internal/emitter/` — server-side config emitters (renders `internal/emit` contract)
+- `internal/osdetect/` — OS detection for renderer dispatch (R-013/R-014)
+
+### Drift detection layer
+- `internal/drift/` — drift detection collector + aggregator (REQ-103..113; R-018/R-019/R-020)
+
+### Security & identity layer (v0.12 — Zero-Trust Identity)
+- `internal/identity/` — OIDC client + auth CLI (REQ-144)
+- `internal/seal/` — master key seal-to-OIDC + Shamir 3-of-5 (REQ-147, D-241, C-35)
+- `internal/webauthn/` — WebAuthn connector for Dex (REQ-148, D-240, C-38)
+- `internal/acl/` — ACL rewrite to OIDC claims, deny-by-default (REQ-122, REQ-145)
+- `internal/audit/` — audit log tamper-evidence (REQ-125, F2)
+- `internal/security/` — SVID chain validation, daemon auth, file-mode enforcement (REQ-123, REQ-124, REQ-126)
+- `internal/config/` — cluster config parsing, frontmatter dispatch (R-014)
+
+### Deprecated / dual-write (removed in v1.x)
+- `internal/transport/` — v0.8 mTLS HTTP layer; superseded by `internal/sshpush/` (dual-write window closed in v0.12 P07; full deletion deferred to v1.x per P23_DUAL_WRITE_DECISION.md)
+
+## Execution gates (v0.12)
+
+The v0.12 milestone is gated by binding conditions C-29..C-38 (see
+GRILL_v0.12.md). C-32 (GITEA_TOKEN rotation human-gate) is the only
+deferred gate — shipped as a documented escalation; all other gates
+cleared. The load-bearing rule is R-021 (no Orca password/token paths).

+# Phase Audit Report Template
+
+Use this template for CIAgent audit reports (`ciagent-audit` workflow).
+Fill each section; mark N/A where a check does not apply (e.g. no active
+phase branch after milestone completion). Keep verdicts binding: PASS /
+FAIL / WARN only — no soft language.
+

+
+# Phase Audit — <milestone> (<milestone summary>)
+
+**Project**: <slug>
+**Milestone**: <version> — <summary>
+**Date**: <YYYY-MM-DD>
+**Branch**: `<current branch>`
+**Result**: <PASS / WARN / FAIL> — <one-line summary>
+
+## Step 1 — Reconstruction Test
+
+- Latest `---ci---` block (HEAD): `project: <slug>, phase: <N>, milestone: <ver>, status: <stage>` — <matches / mismatches> CHECKPOINT.json (`phase: <N>, stage: <stage>`).
+- config.json `milestone: <ver>` — <matches / mismatches>.
+- `make verify-reqs` → <result line> — ROADMAP ↔ REQUIREMENTS <consistent / inconsistent>.
+- <N>/<M> commits have `---ci---` blocks (<%> commit discipline).
+
+## Step 2 — .ciagent/ File Discipline
+
+- `config.json`: <valid / invalid> JSON, required fields <present / missing>: <list gaps>.
+- `PROJECT.md`: required sections <present / missing>: <What This Is / Requirements / Constraints / Key Decisions>.
+- `ROADMAP.md`: phases <match / mismatch> git branches; <merged=complete, active=in-progress>.
+- `REQUIREMENTS.md`: traceability matrix <complete / incomplete>; <N> REQ references.
+- `ARCHITECTURE.md`: components <match / mismatch> actual code structure; <list stale refs>.
+- `PERSONAS.md`: roster <current / stale>.
+
+## Step 3 — Branch Hygiene
+
+- Phase branches: <N> active, <N> merged, <N> orphan.
+- Milestone branches: <N> active, <N> merged.
+- Orphan branches (no `---ci---` commits): <list or "none">.
+- Stale merged branches (should be deleted): <list or "none">.
+
+## Step 4 — Commit Discipline
+
+- Total commits: <N>; with `---ci---`: <N>; without: <N> (<pre-convention legacy, acceptable / unexpected — investigate>).
+- Stale decisions (D-series in `.ciagent/` >50 commits old, not reflected in code): <list or "none">.
+- Unresolved escalations older than timeout: <list or "none">.
+
+## Step 5 — Audit Checks
+
+1. HEAD not on main when phase/milestone branches exist — <PASS / N/A / FAIL>: <detail>.
+2. CHECKPOINT.json exists — <PASS / FAIL>.
+3. CHECKPOINT.json consistent with git status — <PASS / FAIL>: <detail>.
+4. Report template exists (`opencode/ci/references/report-template.md`) — <PASS / FAIL>.
+5. No pending escalations — <PASS / FAIL>: <detail; auto-resolved is OK>.
+6. Milestone version in config consistent — <PASS / FAIL>: config=<ver> vs ROADMAP=<ver> vs checkpoint=<ver>.
