docs(P00): grill v0.8 plan — PROCEED-WITH-CONDITION (4 binding fixes applied)

GRILL_v0.8.md (30KB): 9-axis adversarial review, overall verdict PROCEED-WITH-CONDITION (confidence 0.78). 7 PROCEED + 4 PROCEED-WITH-CONDITION + 0 REPLAN findings. 4 binding plan changes applied to PLAN_v0.8.md: #1 T02.6 relabeled as v0.6 ship-defect bugfix (not v0.8 feature); P04 audit must record ship-defect closure #2 T02.9 doctor proxmox parity — P02 not complete until both bootstrap + doctor callbacks use capture-fix wrapper #3 T01.6 cli coverage escape valve — ship at 65% if 70% not reached after Wave 2 (RESEARCH §1.4 flags 55-65% realistic); do not block P02/P03 on the last 5% #4 T03.1 verify-reqs regex substring-tolerant (matches v0.2 header variant) + reverse-direction assertion (REQUIREMENTS Complete ↔ ROADMAP COMPLETE); scope note: doc-vs-doc drift only T02.10 case 7 added (known_hosts pre-populated v0.6→v0.8 migration path). No escalations; all axes resolved at confidence ≥ 0.60. ---ci--- project: orca phase: 0 milestone: v0.8 status: grill ---/ci---

+# Grill Report: Orca v0.8 — Coverage & Trust Hardening
+
+**Date:** 2026-08-04
+**Reviewer:** ci-griller (red-team, adversarial)
+**Plan under review:** `.ciagent/PLAN_v0.8.md` (commit 4780e4d)
+**Branch:** `phase/00-specify` (milestone `milestone/v0.8-coverage-trust-hardening`)
+**Mode:** Full autonomy
+
+---
+
+## Methodology
+
+Every material claim in `PLAN_v0.8.md` and `RESEARCH_v0.8.md` was cross-checked
+against the actual codebase (verified coverage baselines via `go test -cover`,
+read `internal/proxmox/bootstrap.go:75-234`, `internal/security/ca.go`,
+`internal/doctor/doctor.go`, `.ciagent/ROADMAP.md`, `.ciagent/REQUIREMENTS.md`,
+PERSONAS, ARCHITECTURE) AND the `golang.org/x/crypto` v0.54.0 source for
+`knownhosts.New` / `checkAddr` behavior. The TOFU-capture claim was not taken
+on faith — the upstream `checkAddr` (knownhosts.go:370-385) was read directly.
+
+Findings are scored on the 9 axes. Binding verdicts are **PROCEED**,
+**PROCEED-WITH-CONDITION** (plan proceeds but must incorporate a named change),
+or **REPLAN** (axis has a fatal flaw; revise before execution).
+
+---
+
+## Summary Verdict
+
+| Verdict | Count |
+|---------|-------|
+| PROCEED | 7 |
+| PROCEED-WITH-CONDITION | 4 |
+| REPLAN | 0 |
+
+**Overall verdict: PROCEED-WITH-CONDITION**
+
+The v0.8 plan is fundamentally sound: scope is right-sized, the no-new-deps
+promise holds (verified `ssh.FingerprintSHA256` + `knownhosts.Line` are in the
+existing `golang.org/x/crypto` v0.54.0 dep), the tiered coverage floor (D-047)
+is realistic per-package with the named seams, and the persona territory
+collision on `internal/cli/node.go` is explicitly adjudicated in PERSONAS.md
+(backend owns implementation, lead owns `_test.go`). The 4 conditions below are
+**targeted correctness fixes**, not scope expansions:
+
+1. **P02 must add a regression test asserting first-connect Proxmox join
+   succeeds end-to-end** (the latent TOFU bug means v0.6's first-connect has
+   been broken since ship; the fix in T02.6 is correct but must be proven by a
+   test that would have failed pre-fix).
+2. **P03's verify-reqs regex must match `**COMPLETE**` as a *substring* within
+   the bold span** (v0.2's header `**COMPLETE (merged to main via v0.3)**` is
+   not matched by the current `\*\*COMPLETE\*\*` literal — a silent blind spot).
+3. **P03 must add a second assertion: every REQUIREMENTS row marked `Complete`
+   must reference a milestone ROADMAP marks COMPLETE** (the reverse direction).
+   The v0.7 `cert_repo_test.go` omission (REQ-053 marked Complete but the test
+   file does not exist) proves forward-direction-only checks miss the most
+   dangerous drift class: *claimed-Complete-but-actually-incomplete*.
+4. **P02 T02.6's TOFU fix must be reviewed against `doctor proxmox`'s callback
+   (T02.9) as a paired change, not a follow-on** — they share the exact
+   `knownhosts.New` defect; fixing one and not the other in the same phase
+   creates an inconsistent trust surface.
+
+With these 4 conditions applied, this plan is ready to execute. No REPLAN.
+
+---
+
+## Per-Axis Findings
+
+### Axis 1 — Business Case
+
+#### A1-F1 — Is v0.8 the right next milestone, or polish-for-polish's-sake?
+
+**Evidence:**
+- v0.7 P03 (REQ-055) shipped a ≥50% coverage floor; v0.8 re-baselines six
+  packages still under 50% (engine 8.3%, proxmox 5.1%, cli 27.6%, transport
+  26.3%, store 47.2%, jobspec 47.6%) — **verified identical via `go test
+  -cover`**.
+- RESEARCH §2.1 surfaces a **latent v0.6 defect**: `knownhosts.New` returns
+  `KeyError{Want:[]}` on first connect and does NOT auto-write. Verified
+  directly in `golang.org/x/crypto@v0.54.0/ssh/knownhosts/knownhosts.go:370-385`
+  (`checkAddr` returns `&KeyError{}` with empty `Want` when no line matches).
+  `bootstrap.go:140-142` treats this as a dial failure. **This means
+  first-connect `orca node join --type proxmox` has been broken since v0.6
+  shipped** (the v0.6 RESEARCH §A.5 claim that `knownhosts.New` "handles both
+  capture and verify" was wrong).
+- `bootstrap.go:123` comment is literally false: "on first connect it captures
+  the host key" — it does not.
+
+**Confidence:** 0.90 that v0.8 is the right next milestone.
+**Verdict:** **PROCEED**. v0.8 is not polish-for-polish: it closes a real
+security defect (TOFU broken since v0.6), populates a `Result` field that D-045
+*assumed* was already populated (it isn't — `bootstrap.go:195-198`), and lifts
+coverage off floors that v0.7 explicitly under-shot. The diminishing-returns
+risk is real for the 3 zero-test toe-holds (audit/certpaths/cmd-orca), but
+D-047 tiered them to 50% precisely to avoid the rathole — that call is sound.
+
+---
+
+### Axis 2 — Scope and Requirements
+
+#### A2-F1 — Is the TOFU bugfix correctly scoped into P02, or should it be a hotfix on main?
+
+**Evidence:**
+- The TOFU capture bug (RESEARCH §2.1, PLAN T02.6) is a v0.6 latent defect,
+  not a v0.8 feature. First-connect Proxmox join is broken **today on main**.
+- PLAN bundles the fix into P02 (trust hardening phase) alongside REQ-058
+  (`--host-key-fingerprint`) and REQ-059 (`key-reset`).
+- ROADMAP tags run on the v0.7.x patch line: `v0.7.0` (P0) … `v0.7.4` (P04).
+  P02 ships as `v0.7.2` — i.e., the fix lands on a milestone branch, not main,
+  and only reaches main at P04 merge (`v0.7.4`).
+
+**Confidence:** 0.62 that bundling into P02 is the right call (low confidence —
+this is a judgment call with real downside).
+**Verdict:** **PROCEED-WITH-CONDITION.** The fix is correctly designed (T02.6's
+`KeyError{Want:[]}` capture-and-persist is the right shape), but the plan must
+either (a) document explicitly *why* this isn't hotfixed on main (e.g., "no
+operator has hit first-connect yet because all deployments pre-populate
+`known_hosts` manually — confirmed by the v0.6 ship audit"), OR (b) flag the
+bug in the P04 audit as a v0.6 ship-defect with a post-mortem note. **The plan
+currently treats T02.6 as a feature task; it is a bugfix for shipped code and
+must be labeled as such** so the P04 audit can distinguish "new hardening" from
+"closing a v0.6 gap." Blast radius if T02.6's fix is wrong: every existing
+Proxmox node's `known_hosts` could be re-pinned on next join — moderate, but
+mitigated by T02.10 case 3/4/5 integration tests.
+
+**Condition:** Add a note to T02.6 in PLAN marking it as a **v0.6 ship-defect
+bugfix** (not a v0.8 feature), and ensure P04 audit (T04.2) records it as such.
+
+#### A2-F2 — Are the 3 zero-test packages worth a 50% toe-hold, or scope creep?
+
+**Evidence:**
+- `cmd/orca` is 15 LOC of glue (`main()` → `cli.Execute()`). 50% coverage = ~7
+  lines. RESEARCH §1.1, §5 pitfall #6 explicitly flags the effort:coverage
+  ratio as poor.
+- `internal/certpaths` is 64 LOC of pure path-join functions. 50% is trivial.
+- `internal/audit` is 125 LOC, 4 exported funcs. 50% is trivial.
+- D-047 explicitly tiered these to 50% to avoid a coverage rathole; v0.9 can
+  raise the floor.
+
+**Confidence:** 0.85.
+**Verdict:** **PROCEED.** The tiered floor is the right call. The
+`cmd/orca` toe-hold is low-value but low-cost (one `run() int` refactor + one
+smoke test), and dropping it would leave a `covdata` tooling error in CI output
+that looks like a broken build to a casual reader. Keeping it at 50% is
+defensible.
+
+#### A2-F3 — Scope size: 4 REQs, 37 tasks — too lean, too fat, or right?
+
+**Evidence:**
+- 37 tasks, 36 must-haves, 4 phases each shipping a patch. Comparable to v0.7
+  (5 phases, similar task density).
+- P01 is the heaviest (12 tasks, 9 packages) — the risk concentration is here.
+
+**Confidence:** 0.80.
+**Verdict:** **PROCEED.** Right-sized for an NFR milestone. P01 density is the
+watch item (see Axis 5).
+
+---
+
+### Axis 3 — Architecture and Technical Feasibility
+
+#### A3-F1 — Do the proxmox `sessionRunner` and engine `peerDispatcher` seams leak test concerns into production?
+
+**Evidence:**
+- T01.1 `sessionRunner` (`internal/proxmox/bootstrap.go`): 1 interface,
+  ~10 LOC, `CombinedOutput(cmd) ([]byte, error)`. Default impl wraps
+  `*ssh.Client.NewSession().CombinedOutput(...)`. Backward compatible —
+  existing callers unchanged. This is the **same pattern as the existing
+  `sshDialer` seam** (`bootstrap.go:201-213`), which shipped in v0.6 without
+  concern. The seam is a standard testability extraction, not a test concern
+  leak.
+- T01.2 `peerDispatcher` (`internal/engine/dispatcher.go`): **conditional** —
+  only added if T01.4 cannot hit 70% via `httptest.NewTLSServer` alone. Plan
+  explicitly prefers `httptest.NewTLSServer` (RESEARCH §1.3 gap #2, §5 pitfall
+  #8). This is the right ordering: try the stdlib test fixture first, add the
+  seam only if needed.
+
+**Confidence:** 0.88.
+**Verdict:** **PROCEED.** Both seams are backward-compatible interface
+extractions matching an existing pattern (`sshDialer`). No test-concern leak.
+The conditional-gate on T01.2 is correctly conservative.
+
+#### A3-F2 — Does P02's trust work stay within the existing security boundary?
+
+**Evidence:**
+- P02 touches `internal/proxmox/bootstrap.go` (pinned callback, TOFU fix),
+  `internal/cli/node.go` (flag + subcommand), `internal/security/sshkey.go`
+  (fingerprint helper), `internal/doctor/doctor.go` (T02.9 TOFU fix). All
+  within the existing SSH trust surface established in v0.6.
+- No new crypto, no new CA, no new X.509. `ssh.FingerprintSHA256` is in the
+  existing `golang.org/x/crypto` v0.54.0 dep (verified: not a new direct dep).
+- PERSONAS correctly keeps `security-engineer` deactivated — the work is SSH
+  dialer + known_hosts file manipulation, not new security architecture.
+
+**Confidence:** 0.90.
+**Verdict:** **PROCEED.** Boundary is respected.
+
+#### A3-F3 — T02.9 (doctor proxmox TOFU fix) is a paired change with T02.6, not a follow-on
+
+**Evidence:**
+- `internal/doctor/doctor.go:412` uses the **exact same** `knownhosts.New(...)`
+  callback pattern as `bootstrap.go:125`. Both share the latent defect.
+- T02.9 is listed as a separate task ("Apply the TOFU capture-fix to `doctor
+  proxmox` probe") but is in the same Wave 2 as T02.6. If T02.6 lands and T02.9
+  doesn't (e.g., a mid-phase blocker), the trust surface is **inconsistent**:
+  join captures, doctor fails.
+
+**Confidence:** 0.75.
+**Verdict:** **PROCEED-WITH-CONDITION.** T02.6 and T02.9 must be reviewed as a
+paired change in P02 verification — the phase is not done until BOTH callbacks
+use the capture-fix wrapper. Add to P02 Verification: "doctor proxmox
+first-connect → captures + succeeds (mirrors T02.10 case 3 for bootstrap)."
+
+**Condition:** Add a P02 verification line asserting doctor proxmox
+first-connect parity with bootstrap.
+
+---
+
+### Axis 4 — People, Skills, and Organization
+
+#### A4-F1 — Territory collision on `internal/cli/node.go`
+
+**Evidence:**
+- PERSONAS.md line 62: lead-developer territory = `internal/cli/**`.
+- PERSONAS.md line 70: backend-engineer territory = `internal/cli/node.go`.
+- PERSONAS.md line 107 explicitly adjudicates: "backend owns the command
+  implementation; lead owns the test files (`node_test.go`)."
+- Territory mode is `warn` (not `block`) — collisions log but don't fail.
+
+**Confidence:** 0.82.
+**Verdict:** **PROCEED.** The collision is **explicitly adjudicated** in
+PERSONAS.md with a clean boundary (impl vs test files). This is the right
+answer. The `warn` mode means a backend commit touching `node_test.go` (or a
+lead commit touching `node.go` impl) would log — acceptable for a 3-persona
+team. No replan.
+
+#### A4-F2 — Key-person dependency: is the 3-persona roster sufficient?
+
+**Evidence:**
+- 3 active personas, all retained from v0.7. No phase-specific personas.
+- backend-engineer owns 60%+ of P02 (the security-critical phase). If
+  backend-engineer is unavailable, P02 stalls entirely.
+
+**Confidence:** 0.70.
+**Verdict:** **PROCEED.** Key-person risk is real but inherent to a 3-persona
+NFR milestone. The work is not novel (refining existing surface), so the bus
+factor is acceptable for hardening. Flagged, not blocking.
+
+---
+
+### Axis 5 — Timeline and Estimates
+
+#### A5-F1 — Is the 70% coverage target for 6 packages in one phase (P01) realistic?
+
+**Evidence:**
+- RESEARCH §1.1 + §1.4 per-package achievability assessments:
+  - engine → 70% REALISTIC (with LocalExecutor stubs + `openTestDB`).
+  - proxmox → 70% REALISTIC **but requires the `sessionRunner` seam (T01.1)** —
+    without it, only 50-55% (validation paths + sudoersContent asserts, already
+    done).
+  - cli → 70% AMBITIOUS (17 files, ~2000 LOC); RESEARCH says "55-65% is more
+    realistic for one phase" even with `daemon.go` excluded.
+  - transport → 70% REALISTIC (`httptest.NewTLSServer` is standard).
+  - store → 70% REALISTIC (cert_repo_test.go gap is the main lift).
+  - jobspec → 70% REALISTIC (easiest of the six).
+- **`internal/cli` is the swing package.** RESEARCH explicitly says 55-65% is
+  the realistic single-phase outcome, not 70%. The plan sets the floor at 70%
+  "excluding daemon.go" — but even excluding daemon.go, RESEARCH's own evidence
+  says 70% is a stretch.
+
+**Confidence:** 0.65 (split: 5 of 6 packages at 0.85, cli at 0.45).
+**Verdict:** **PROCEED-WITH-CONDITION.** The plan must add an explicit fallback
+for `internal/cli`: if T01.6 hits ≥65% (excluding daemon.go) but not 70% after
+a reasonable effort, the phase ships at 65% with a documented note + a v0.9
+follow-up to lift to 70%. **Hard-requiring 70% on cli risks a coverage rathole
+that delays the entire milestone** (P02/P03 are gated on P01 ship). The other 5
+packages at 70% is realistic.
+
+**Condition:** Add to T01.6 acceptance criterion: "If ≥65% (excluding
+daemon.go) is achieved but 70% is not after Wave 2 effort, document the gap in
+the task comment + record a v0.9 follow-up; ship at 65%. Do NOT block P02/P03
+on the last 5% of cli coverage." (This mirrors RESEARCH §1.4's own flag, which
+the plan currently does not carry forward as an escape valve.)
+
+---
+
+### Axis 6 — Budget and Financial Realism
+
+#### A6-F1 — Zero new deps: is that realistic given P02's needs?
+
+**Evidence:**
+- `ssh.FingerprintSHA256`: verified in `golang.org/x/crypto/ssh` (direct dep
+  since v0.6 D-030).
+- `knownhosts.Line` / `Normalize` / `KeyError`: same `golang.org/x/crypto`
+  module (already imported in `bootstrap.go:32` and `doctor.go:29`).
+- `verify-reqs`: stdlib only (`regexp`, `os`, `fmt`).
+- `go.mod` unchanged by v0.8 (PLAN line 62).
+
+**Confidence:** 0.95.
+**Verdict:** **PROCEED.** Zero-new-deps is verified and realistic.
+
+---
+
+### Axis 7 — Risks, Assumptions, and Dependencies
+
+#### A7-F1 — The 10 pitfalls: are mitigations real or hand-waves?
+
+**Evidence (spot-check of the 4 most material pitfalls):**
+- **Pitfall #1 (TOFU broken):** Mitigation T02.6 is **concrete and correct** —
+  wrap `knownhosts.New`, capture on `KeyError{Want:[]}` via `knownhosts.Line` +
+  `security.WriteAtomic`, return nil. Verified against x/crypto v0.54.0
+  `checkAddr` semantics. **Real mitigation.**
+- **Pitfall #2 (Result.HostKeyFingerprint never populated):** T02.7 adds
+  `ssh.FingerprintSHA256(hostKey)`. 1-line once host key is available. **Real.**
+- **Pitfall #3 (no sessionRunner seam):** T01.1 adds it, ~10 LOC. **Real.**
+- **Pitfall #10 (writeAtomic unexported):** T02.2 exports it. Verified
+  `ca.go:305` — `func writeAtomic(...)` is indeed unexported. **Real.**
+
+**Confidence:** 0.88.
+**Verdict:** **PROCEED.** Mitigations are concrete, not hand-waves.
+
+#### A7-F2 — TOFI bugfix blast radius if P02's fix is wrong
+
+**Evidence:**
+- T02.6 changes the `HostKeyCallback` for every `orca node join --type proxmox`
+  + every `doctor proxmox` probe. If the capture-and-persist logic is wrong,
+  every existing Proxmox node's `known_hosts` could be corrupted (e.g.,
+  duplicate entries, wrong-format lines, partial writes on crash).
+- Mitigations: T02.10 integration tests (cases 3/4/5 cover first-connect,
+  second-connect, mismatch); AD-029 atomic rewrite via `security.WriteAtomic`.
+- **Gap:** no test for "known_hosts already has an entry, join re-connects" —
+  i.e., the idempotent re-run path after the fix. T02.10 case 4 covers
+  second-connect-match, but not "known_hosts was written by the OLD (broken)
+  code path and is now being read by the NEW code path."
+
+**Confidence:** 0.70.
+**Verdict:** **PROCEED-WITH-CONDITION.** T02.10 must add a case for
+"known_hosts pre-populated in the expected format (e.g., from a manual
+`ssh-keyscan` or a prior v0.6 deployment that somehow succeeded) →
+second-connect matches + succeeds." This covers the migration path from
+v0.6's (broken) state to v0.8's fixed state.
+
+**Condition:** Add T02.10 case 7: "known_hosts pre-populated with a valid
+OpenSSH line for the host → connect matches + succeeds (covers v0.6→v0.8
+migration)."
+
+---
+
+### Axis 8 — Governance, Decision-Making, and Communication
+
+#### A8-F1 — Does `make verify-reqs` actually prevent drift, or is it cosmetic?
+
+**Evidence:**
+- T03.1 regex (PLAN line 216):
+  - ROADMAP milestone-complete: `^##\s*Milestone\s+v0\.\d+:.*—\s*\*\*COMPLETE\*\*`
+  - REQUIREMENTS row: `^\|\s*(REQ-\d+)\s*\|.*?\|\s*\*\*(Complete|Pending)\*\*\s*\|`
+- **ROADMAP v0.2 header (line 23):** `## Milestone v0.2: Networking,
+  Observability, Security Hardening — **COMPLETE (merged to main via v0.3)**`
+- The regex `\*\*COMPLETE\*\*` requires the literal `**COMPLETE**` with closing
+  `**` immediately after `COMPLETE`. v0.2's header has `**COMPLETE (merged to
+  main via v0.3)**` — the `**` closes after the parenthetical, NOT after
+  `COMPLETE`. **The regex does NOT match v0.2 as complete.**
+- **Consequence:** all v0.2 REQs (REQ-011, 014, 023, 025-040) are **silently
+  exempted** from the check. A stale v0.2 REQ-035 row (marked Pending) would
+  NOT fail the gate.
+- **ROADMAP v0.6 has TWO headers** (line 92 without COMPLETE, line 94 with) —
+  the regex matches line 94, but the duplicate is a markdown smell that could
+  confuse the milestone→REQ mapping if the parser takes the first match.
+
+**Confidence:** 0.92 (high — the regex mismatch is verifiable).
+**Verdict:** **PROCEED-WITH-CONDITION.** The regex must match `**COMPLETE**`
+as a *substring within the bold span*, not as a literal `**COMPLETE**` token.
+Change to `—\s*\*\*[^*]*COMPLETE[^*]*\*\*` (matches `**COMPLETE**`,
+`**COMPLETE (merged to main via v0.3)**`, and any future variant). Add a
+golden-file test case (T03.2) with the v0.2-style parenthetical header to
+prevent regression.
+
+**Condition:** T03.1 regex changed to substring-match COMPLETE within the bold
+span; T03.2 adds a golden fixture with `**COMPLETE (merged to main via v0.3)**`.
+
+#### A8-F2 — Is the single-direction check (ROADMAP→REQUIREMENTS) enough?
+
+**Evidence:**
+- PLAN line 35-37 explicitly scopes out the reverse direction: "forward
+  direction (ROADMAP-shipped → REQUIREMENTS Complete) is the priority per the
+  v0.7 drift that motivated REQ-060."
+- **But the v0.7 drift had TWO symptoms:**
+  1. ROADMAP said COMPLETE, REQUIREMENTS said Pending (forward drift — caught
+     by the current check).
+  2. **REQ-053 was marked Complete in REQUIREMENTS, but
+     `internal/store/cert_repo_test.go` was never written** — verified: only
+     `cert_repo.go` exists in `internal/store/`. The "Complete" status was
+     false. **No markdown-based check can catch this** (it's a code-vs-doc
+     drift, not a doc-vs-doc drift).
+- The reverse-direction check (REQUIREMENTS Complete ↔ ROADMAP COMPLETE) would
+  catch a different class: a REQ marked Complete in REQUIREMENTS for a
+  milestone ROADMAP does NOT mark COMPLETE (e.g., premature marking). This is
+  a cheaper class of drift but still real.
+
+**Confidence:** 0.78.
+**Verdict:** **PROCEED-WITH-CONDITION.** Add the reverse-direction assertion
+to T03.1 (it's ~10 LOC on top of the existing parser — same maps, just diff
+both ways). Document explicitly that **no markdown check can catch the
+code-vs-doc drift** (REQ-053 case) — that requires a code-level audit
+(`ciagent-audit` in P04). The plan should note this as a known limitation of
+REQ-060, not pretend the gate is complete.
+
+**Condition:** T03.1 adds reverse-direction assertion; PLAN adds a note that
+REQ-060 catches doc-vs-doc drift only, not code-vs-doc (the REQ-053
+cert_repo_test.go case).
+
+#### A8-F3 — Is there a "stop the project" trigger?
+
+**Evidence:** P04 (T04.1-T04.9) is the final review + ship. No explicit
+"stop" trigger if P01 coverage stalls or P02 TOFU fix proves unfixable.
+
+**Confidence:** 0.60.
+**Verdict:** **PROCEED.** The 4-phase structure with per-phase tags means a
+stall is visible (phase tag doesn't ship). Acceptable for an NFR milestone.
+
+---
+
+### Axis 9 — Change, Adoption, and Operational Readiness
+
+#### A9-F1 — Who benefits from v0.8? Is there operator pull for `--host-key-fingerprint`?
+
+**Evidence:**
+- `--host-key-fingerprint` (REQ-058) is operator-facing: pre-pinning a
+  Proxmox host's SSH key before first join. This is the standard
+  high-security-deployment pattern (the v0.6 D-035 caveat explicitly promised
+  it as a "future enhancement").
+- `orca node key-reset` (REQ-059) is operator-facing: the `ssh-keygen -R`
+  equivalent for orca's known_hosts.
+- The TOFU bugfix (T02.6) benefits **every operator who has tried
+  first-connect Proxmox join since v0.6** — i.e., it fixes a feature that was
+  advertised as working but wasn't.
+- Coverage uplift (REQ-057) is developer-facing (no operator pull).
+- verify-reqs (REQ-060) is internal-governance (no operator pull).
+
+**Confidence:** 0.82.
+**Verdict:** **PROCEED.** The trust features have real operator pull
+(pre-pinning is a documented security best practice; the v0.6 caveat promised
+it). The coverage + hygiene work is internal-debt paydown — justified by the
+v0.7 under-shot, not by operator demand. The mix is appropriate for an NFR
+milestone.
+
+#### A9-F2 — Rollback plan if P02's trust changes go wrong
+
+**Evidence:**
+- P02 changes `HostKeyCallback` for all Proxmox joins + doctor probes. If the
+  capture-fix corrupts `known_hosts`, the rollback is: revert the phase commit
+  + manually restore `known_hosts` from backup.
+- No data migration in P02 (known_hosts is a flat file; atomic rewrite via
+  `WriteAtomic` preserves crash safety).
+- `key-reset` (T02.8) is local-only (D-046) — no remote side effects to
+  reverse.
+
+**Confidence:** 0.80.
+**Verdict:** **PROCEED.** Rollback is straightforward (revert + file restore).
+The atomic-rewrite requirement (AD-029) is the right mitigation.

+
+## Required Plan Changes (4 conditions)
+
+1. **T02.6 labeling (A2-F1):** Add a note to T02.6 in `PLAN_v0.8.md` marking
+   it as a **v0.6 ship-defect bugfix** (first-connect Proxmox join has been
+   broken since v0.6 shipped due to `knownhosts.New` returning
+   `KeyError{Want:[]}` with no capture-and-persist). P04 audit (T04.2) must
+   record it as a ship-defect closure, not a v0.8 feature.
+
+2. **P02 verification parity for doctor (A3-F3):** Add to Phase 2 Verification:
+   "`doctor proxmox` first-connect on a node with empty known_hosts → captures
+   the key + writes known_hosts + probe succeeds (mirrors T02.10 case 3 for
+   bootstrap). T02.6 and T02.9 are a paired change; the phase is not complete
+   until both callbacks use the capture-fix wrapper."
+
+3. **T01.6 cli coverage escape valve (A5-F1):** Add to T01.6 acceptance
+   criterion: "If ≥65% (excluding `daemon.go`) is achieved but 70% is not after
+   Wave 2 effort, document the gap in a test-file comment + record a v0.9
+   follow-up; ship P01 at 65% for cli. Do NOT block P02/P03 on the last 5% of
+   cli coverage." (Carries forward RESEARCH §1.4's own flag as an explicit
+   escape valve.)
+
+4. **verify-reqs regex + reverse direction (A8-F1 + A8-F2):**
+   - Change T03.1 ROADMAP-complete regex from
+     `^##\s*Milestone\s+v0\.\d+:.*—\s*\*\*COMPLETE\*\*` to
+     `^##\s*Milestone\s+v0\.\d+:.*—\s*\*\*[^*]*COMPLETE[^*]*\*\*` (substring
+     match within the bold span — handles `**COMPLETE**`,
+     `**COMPLETE (merged to main via v0.3)**`, and future variants).
+   - Add T03.2 golden fixture: a ROADMAP with
+     `**COMPLETE (merged to main via v0.3)**` → assert the milestone is
+     detected as complete.
+   - Add reverse-direction assertion to T03.1: every REQUIREMENTS row marked
+     `**Complete**` must reference a milestone ROADMAP marks COMPLETE (catches
+     premature-Complete drift).
+   - Add a PLAN note: "REQ-060 catches doc-vs-doc drift only. Code-vs-doc
+     drift (e.g., REQ-053 marked Complete but `cert_repo_test.go` missing —
+     verified missing in v0.7 ship) is NOT caught by this gate; it requires
+     the P04 `ciagent-audit` code-level review."
+
+Additionally (lower-priority, from A7-F2):
+
+5. **T02.10 case 7 (A7-F2):** Add integration test case: "known_hosts
+   pre-populated with a valid OpenSSH line for the host (simulating a v0.6
+   deployment or manual `ssh-keyscan`) → connect matches + succeeds. Covers
+   the v0.6→v0.8 migration path."
+
+---
+
+## Escalations
+
+None. All 9 axes resolved at confidence ≥ 0.60. No axis requires escalation to
+the operator; the 4 conditions are within the plan-author's authority to apply
+before P01 execution begins.
+
+---
+
+## What the Plan Is NOT Doing (and should it?)
+
+- **Not lifting the 3 zero-test packages to 70%.** Correct per D-047 — deferred
+  to v0.9. Not a gap.
+- **Not adding a `peerDispatcher` seam unless needed.** Correct — conditional
+  on T01.4's 70% via `httptest.NewTLSServer`. Not a gap.
+- **Not pre-populating `known_hosts` from a remote keyscan API.** Correct —
+  TOFU + manual `--host-key-fingerprint` cover the v0.8 surface. Not a gap.
+- **Not catching code-vs-doc drift in verify-reqs.** **Known limitation** —
+  REQ-060 is a markdown-vs-markdown check. The REQ-053
+  `cert_repo_test.go`-missing case proves this class of drift is real. P04
+  `ciagent-audit` is the backstop. Documented in condition #4.
+
+---
+
+## Simplest 80%-of-the-value version
+
+If forced to cut v0.8 to its smallest valuable form: **keep P02 (trust
+hardening + TOFU bugfix) and P03 (verify-reqs); drop P01's coverage uplift for
+the 3 zero-test packages + cli.** The TOFU bugfix alone (T02.6 + T02.9) fixes a
+shipped security defect — that's the highest-value work. The verify-reqs gate
+prevents the v0.7 drift from recurring. The coverage uplift on the 6
+under-50% packages is valuable but not urgent; the 3 zero-test toe-holds are
+the lowest-value work in the milestone. **The plan as written does not over-
+scope** — it includes all of the above because the marginal cost is low — but
+if P01 slips, the 3 toe-holds + cli are the first cuts to make.
+
+---
+
+## What Would Have to Be True for v0.8 to Succeed in the Next 90 Days
+
+1. The `sessionRunner` seam (T01.1) unlocks proxmox 70% — **plausible** (same
+   pattern as the existing `sshDialer` seam).
+2. `httptest.NewTLSServer` suffices for transport 70% without a new seam —
+   **plausible** (standard Go testing fixture).
+3. The TOFU capture-fix (T02.6) is correct — **plausible** (verified against
+   x/crypto v0.54.0 semantics; integration tests T02.10 cover the cases).
+4. `verify-reqs` regex matches all ROADMAP milestone header variants — **NOT
+   true today** (v0.2 header mismatch — condition #4 fixes this).
+5. cli hits 70% in one phase — **NOT confirmed** (RESEARCH says 55-65%;
+   condition #3 adds the escape valve).
+
+(4) and (5) are the two conditions that move the plan from "optimistic" to
+"sound." Both are addressed by the 4 required changes.
+
+---
+
+**End of grill report.** Apply the 4 conditions to `PLAN_v0.8.md` before P01
+execution. No REPLAN; no escalations. Overall verdict: **PROCEED-WITH-
+CONDITION** (confidence 0.78).

+reason: |
+  Orca v0.8 is an NFR coverage & trust-hardening milestone. The work is
+  test coverage uplift across 9 packages (P01), SSH trust-surface
+  hardening in the existing proxmox + cli/node + security packages (P02),
+  and a requirements-hygiene Go program + Makefile target (P03). No
+  schema changes, no new security architecture, no packaging/distribution,
+  no UI.
+
+  Roster changes vs v0.7:
+  - lead-developer: RETAINED — owns cmd/orca smoke test, internal/cli
+    coverage (cert/doctor/audit/status/version subcommands), and the
+    cmd/verify-reqs Go program (coordination + glue-code territory).
+  - backend-engineer: RETAINED — owns internal/transport + internal/engine
+    tests (httptest.NewTLSServer, LocalExecutor stubs, PeerRegistry) and
+    the SSH trust-surface in internal/proxmox/bootstrap.go (pinned
+    host-key callback, TOFU capture fix, sessionRunner seam) plus
+    internal/cli/node.go (--host-key-fingerprint flag, key-reset
+    subcommand). Frameworks updated: connectrpc REMOVED (not in go.mod
+    per AD-014), golang.org/x/crypto/ssh ADDED (direct dep since v0.6).
+  - data-engineer: RETAINED — owns internal/store tests (cert_repo_test.go
+    gap + coverage uplift), internal/audit tests (sqlite-backed
+    audit_log asserts), internal/certpaths tests (path-join asserts),
+    and internal/jobspec tests (golden HCL fixtures). Frameworks
+    updated: modernc/sqlite + iter (matches actual go.mod).
+  - security-engineer: remains DEACTIVATED — v0.8 refines the existing
+    proxmox SSH trust surface (pinned callback, key-reset) but does NOT
+    add new security architecture. The trust work is backend-engineer
+    territory (it's SSH dialer + known_hosts file manipulation, not
+    X.509/CA/crypto code).
+  - cli-engineer: remains DEACTIVATED — merged into lead-developer
+    (cli coverage is test-only; --host-key-fingerprint and key-reset
+    are 1-flag + 1-subcommand additions to the existing node.go).
+  - devops-engineer: remains DEACTIVATED — verify-reqs is a Go program
+    (lead-developer territory), not a CI/packaging change. The
+    .coreci.yml edit is a 3-line validate-pipeline hook.
+  - network-engineer: remains DEACTIVATED — no transport/mTLS surface
+    change (transport coverage is test-only on the existing mTLS layer).

+- **Territory**: `cmd/**`, `internal/cli/**`, `cmd/verify-reqs/**`, `Makefile`, `.coreci.yml`, `.ciagent/**`
+- **Active**: true
+- **Reason**: Owns P01 coverage for `cmd/orca` (smoke test of `main()`/`cli.Execute()`), `internal/cli` coverage for the non-node, non-daemon subcommands (`cert *`, `doctor *`, `audit list`, `status`, `version`), and the P03 `cmd/verify-reqs/main.go` Go program + `make verify-reqs` Makefile target + `.coreci.yml` validate-pipeline hook. Added `coverage-floor-70` constraint (D-047 tiered floor: 70% for the 6 under-50% packages, 50% for the 3 zero-test packages). Added `testing` + `net/http/httptest` to frameworks (test-only phase).

+- **Active**: true
+- **Reason**: Owns P01 coverage for `internal/transport` (httptest.NewTLSServer for mTLS + stubDispatcher for DispatchClient) and `internal/engine` (LocalExecutor stubs + PeerRegistry in-memory tests). Owns P02 SSH trust hardening: `--host-key-fingerprint` pinned callback in `internal/proxmox/bootstrap.go` (D-045 OpenSSH SHA256:base64 format, AD-027/AD-028), the TOFU capture-fix (knownhosts.New returns KeyError{Want:[]} on first connect — must capture-and-persist via knownhosts.Line, AD-029 atomic rewrite), the `sessionRunner` seam refactor (P01 enabler for proxmox coverage), and `internal/cli/node.go` `--host-key-fingerprint` flag + `key-reset` subcommand (D-046 local known_hosts only). Frameworks updated: `connectrpc` REMOVED (not in go.mod per AD-014 — config.json still lists it but it's a stale entry), `golang.org/x/crypto/ssh` + `knownhosts` ADDED (direct dep since v0.6 D-030).

+- **Active**: true
+- **Reason**: Owns P01 coverage for `internal/store` (including the missing `cert_repo_test.go` — a v0.7 P01 leftover; Insert/Get/List/ListByNode/LatestForKind/PruneOlderThan/Delete + N=3 rotation history per REQ-025), `internal/audit` (sqlite-backed audit_log row asserts via `engine.Audit` + `store.AuditRepo`, slog capture via test handler), `internal/certpaths` (path-join asserts with temp dir + ORCA_HOME/ORCA_DB env), and `internal/jobspec` (golden-file HCL fixtures in a new `testdata/` dir + error-path table for Parse/Validate/ParseFile). Frameworks updated: `iter` + `hashicorp/hcl/v2` added (matches actual go.mod — jobspec uses hclsimple; store Watch uses iter.Seq). Added `coverage-floor-70` constraint.
+
+### cli-engineer
+- **Active**: false (v0.8)
+- **Reason**: Deactivated — merged into lead-developer. The cli coverage work is test-only; `--host-key-fingerprint` and `key-reset` are a 1-flag and 1-subcommand addition to the existing `internal/cli/node.go`, not a new CLI subsystem.
+
+### security-engineer
+- **Active**: false (v0.8)
+- **Reason**: Deactivated — v0.8 refines the existing proxmox SSH trust surface (pinned host-key callback, key-reset known_hosts rewrite) but does NOT add new security architecture (no new CA, no new X.509, no new crypto). The trust work is backend-engineer territory (SSH dialer + known_hosts file manipulation). The `internal/security/sshkey.go` is unchanged in v0.8. Was active in v0.6 (SSH keygen + sudoers), deactivated in v0.7, remains deactivated in v0.8.
+
+### devops-engineer
+- **Active**: false (v0.8)
+- **Reason**: Deactivated — `verify-reqs` is a Go program (`cmd/verify-reqs/main.go`), not a CI/packaging change. The `.coreci.yml` edit is a 3-line validate-pipeline hook (lead-developer territory). No install.sh, Dockerfile, or release-pipeline surface in v0.8.
+
+### network-engineer
+- **Active**: false (v0.8)
+- **Reason**: Deactivated — no transport/mTLS surface change. `internal/transport` coverage is test-only on the existing mTLS layer (httptest.NewTLSServer, no new TLS config). The SSH trust work is point-to-point bootstrap, not the mTLS mesh network-engineer owns.

+- **Key overlaps in v0.8** (lead-developer adjudicates):
+  - `internal/cli/node.go` — backend-engineer (`--host-key-fingerprint` flag + `key-reset` subcommand + proxmox pass-through) vs lead-developer (cli coverage tests). Boundary: backend owns the command implementation; lead owns the test files (`node_test.go`).
+  - `internal/proxmox/bootstrap.go` — backend-engineer (pinned callback, TOFU fix, sessionRunner seam) vs data-engineer (no overlap — proxmox has no store/audit code). Clean boundary.
+  - `cmd/verify-reqs/main.go` — lead-developer (Go program + Makefile + .coreci.yml) vs data-engineer (no overlap — verify-reqs parses markdown, not DB). Clean boundary.
+  - `internal/store/cert_repo_test.go` — data-engineer (test file) vs backend-engineer (no overlap — cert_repo is data territory). Clean boundary.

-  - `internal/doctor/doctor.go` `Proxmox()` — reuses `internal/proxmox` SSH client (security) but check scaffolding clones `doctor.Network()` pattern. Backend-engineer adjudicates (network-engineer deactivated).
-  - `internal/store/node_repo.go` — data-engineer territory, but the `UpdateLastSeenAndOS` caller is `internal/cli/init.go` (backend). Standard repo-consumer boundary.

+# Phase 4 Verification Report — v0.7: --pprof Opt-in on orca daemon
+
+**Phase**: 4  
+**Branch**: `phase/04-pprof-daemon`  
+**REQ Coverage**: REQ-056  
+**Milestone**: v0.7 (Hardening & Completion)
+
+## Structural Verification
+
+### Files Created
+- `internal/daemon/pprof.go` — `StartPprof(addr, log) (*http.Server, error)`: dedicated mux + server, disabled by default, WARN log
+- `internal/daemon/pprof_test.go` — 5 tests (disabled, enabled, shutdown, mux isolation, full server lifecycle)
+- `internal/cli/daemon_test.go` — `TestDaemonPprofFlag` (flag registration + default)
+
+### Files Modified
+- `internal/daemon/server.go` — `PprofAddr` in Options, `pprofServer` field, `NewServer` starts pprof, `Shutdown` stops both
+- `internal/cli/daemon.go` — `--pprof` flag, `PprofAddr` in daemon.Options, conditional startup output line
+
+## Behavioral Verification
+
+### Test Results
+```
+go test ./...               → all PASS (exit 0)
+go test -race ./internal/daemon/... ./internal/cli/... → all PASS
+go vet ./...                → clean
+make build                  → clean
+```
+
+### CLI Verification
+```
+./bin/orca daemon --help → shows --pprof string flag (default "")
+```
+
+### Live Smoke Test
+- `--pprof 127.0.0.1:16060` → WARN logged, `/debug/pprof/` returns 200, `/debug/pprof/cmdline` 200, `/debug/pprof/heap` 200
+- `/healthz` on pprof listener → 404 (mux isolation confirmed, AD-024)
+- Clean shutdown stops both servers
+
+## Security Verification
+
+- pprof on a **separate** `*http.Server` + `*http.ServeMux`, never on the mTLS daemon listener (AD-024) — verified by `TestStartPprof_MuxIsolated` (`/healthz` returns 404 on pprof mux)
+- Default **disabled** — no pprof listener unless `--pprof` is explicitly set
+- WARN log on startup: "unauthenticated, operator-only — do not expose publicly"
+- No `import _ "net/http/pprof"` side-effect registration on `DefaultServeMux` — all handlers explicitly registered on the dedicated mux
+
+## Quality Verification
+
+- No new dependencies (stdlib `net/http`, `net/http/pprof`, `log/slog`, `time` only)
+- No comments added (per project convention)
+- `go.mod` unchanged
+- Test style matches existing `server_test.go`
+
+## Must-Haves Checklist
+
+- [x] `internal/daemon/pprof.go` — `StartPprof` with dedicated mux, all pprof handlers
+- [x] `internal/daemon/server.go` — `PprofAddr` in Options, `pprofServer` field, lifecycle integration
+- [x] `internal/cli/daemon.go` — `--pprof` flag, passed to Options, conditional startup output
+- [x] `internal/daemon/pprof_test.go` — 5 tests (disabled, enabled, shutdown, mux isolation, lifecycle)
+- [x] `internal/cli/daemon_test.go` — flag registration test
+- [x] AD-024: pprof mux separate from mTLS daemon mux (verified by test)
+
+## Verdict
+
+**PASS** — all 4 verification layers pass. REQ-056 is fully covered. The `--pprof` opt-in endpoint runs on a separate listener with a dedicated mux, is disabled by default, and logs a WARN when enabled. I-308 (deferred since v0.2) is now implemented.

+# Phase Plans: Orca v0.8 — Coverage & Trust Hardening
+
+All 4 execution phases + final review with vertical-slice structure, wave
+ordering, persona assignment, and REQ-ID mapping. v0.8 scope: **Coverage &
+Trust Hardening** — round-2 test coverage uplift across 9 packages (tiered
+floor: ≥70% for 6 retested, ≥50% for 3 zero-test per D-047), SSH trust
+hardening (`--host-key-fingerprint` pre-pin + `orca node key-reset` + latent
+TOFU capture-fix + `Result.HostKeyFingerprint` population), and a
+requirements-hygiene gate (`make verify-reqs`).
+
+Branching: `phase/01-coverage-round2`..`phase/04-final-review-ship` on the
+`milestone/v0.8-coverage-trust-hardening` branch (numbering restarts per
+milestone per branch-strategy.md).
+
+Milestone type: **NFR** (P01 test, P02 chore on the trust surface per D-043,
+P03 chore, P04 docs/review). Tags run on the v0.7.x patch line: `v0.7.0`
+(P0) … `v0.7.4` (P04 = milestone release).
+
+**Vertical-slice integrity**: each phase is independently shippable.
+- **P01** ships tests-only (no production code changes except the proxmox
+  `sessionRunner` seam, a backward-compatible interface extraction, and the
+  engine `peerDispatcher` seam per RESEARCH §1.3).
+- **P02** ships the SSH trust features + TOFI bugfix + `Result` population.
+- **P03** ships the hygiene gate (Go program + Makefile + CI hook).
+- **P04** is review + ship + audit (no new REQs).
+
+**Out of scope for v0.8** (candidate for v0.9, noted not added):
+- Lifting the 3 zero-test packages from 50% → 70% (D-047 explicitly
+  toes-holds them; v0.9 can raise the floor).
+- A `peerDispatcher` interface seam in engine beyond what P01 needs for 70%
+  coverage (httptest.NewTLSServer suffices; the seam is only added if
+  coverage cannot otherwise hit 70%).
+- Pre-populating `known_hosts` from a remote keyscan API (TOFU + manual
+  `--host-key-fingerprint` cover the v0.8 trust surface).
+- `verify-reqs` reverse-direction check (REQUIREMENTS Complete ↔ ROADMAP
+  COMPLETE both ways) — forward direction (ROADMAP-shipped → REQUIREMENTS
+  Complete) is the priority per the v0.7 drift that motivated REQ-060.
+
+**Carried-forward research findings** (RESEARCH_v0.8.md, must incorporate):
+- §1.1 per-package coverage strategies + tiered floors (D-047).
+- §1.3 injected seams: reuse `sshDialer` (proxmox), `LocalExecutor` (engine),
+  `Dispatcher` (transport), `watchInterval` (store), `openTestDB`/`withFastWatch`/`initTestEnv`/`resetRootFlags`/`stubDispatcher` helpers.
+- §1.4 realism flags: cli excludes `daemon.go`; `cmd/orca` 50% toe-hold only;
+  proxmox needs the `sessionRunner` seam to hit 70%.
+- §2.1 latent TOFU capture bug (knownhosts.New returns KeyError{Want:[]} on
+  first connect and does NOT auto-write — current BootstrapProxmox treats it
+  as a dial failure).
+- §2.2 `Result.HostKeyFingerprint` is declared but never populated (always
+  `""`); P02 must add `ssh.FingerprintSHA256` computation.
+- §2.3 `--host-key-fingerprint` plugs in at `internal/cli/node.go` (flag) +
+  `internal/proxmox/bootstrap.go` (pinned callback).
+- §2.4 `key-reset` is local-known_hosts-only (D-046), atomic rewrite (AD-029).
+- §3 verify-reqs is a Go program at `cmd/verify-reqs/main.go` (~80 LOC,
+  stdlib only, AD-030) + `make verify-reqs` + `.coreci.yml` validate hook.
+- §4 AD-025..AD-030 (renumbered AD-027..AD-030 in research for SSH/trust;
+  AD-025/AD-026 from earlier milestones are stable).
+- §5 10 pitfalls carried into the risk register at the end of this file.
+
+**Dependencies (RESEARCH §6)**: v0.8 adds **zero** new direct dependencies.
+`ssh.FingerprintSHA256`, `knownhosts.Line`/`Normalize`/`KeyError` are in the
+existing `golang.org/x/crypto` v0.54.0 dep. `verify-reqs` is stdlib-only.
+`go.mod` is unchanged by v0.8.

Mock the proxmox path via `sshDialer` + `sessionRunner` seams. `daemon.go` is excluded — covered by `internal/daemon/server_test.go`. `go test -cover ./internal/cli` → ≥ 70% of non-daemon files (document the exclusion in a test-file comment). **GRILL condition #3 escape valve**: if 70% is not reached after Wave 2 effort and ≥ 65% is achieved (RESEARCH §1.4 flags 55-65% as realistic for one phase), ship cli at 65% and do NOT block P02/P03 on the last 5%; record the shortfall + rationale in the P01 verification commit. |

+## Phase 2: SSH Trust Hardening (REQ-058, REQ-059)
+
+**Branch**: `phase/02-ssh-trust-hardening`
+**REQ Coverage**: REQ-058, REQ-059
+**Tag**: `v0.7.2`
+**Depends on**: Phase 1 (proxmox `sessionRunner` seam from T01.1 is in place;
+the trust-surface code is now testable)
+**Source research**: RESEARCH_v0.8.md §2 (TOFU bug, fingerprint computation,
+flag wiring, key-reset atomic rewrite) + §4 AD-027..AD-029
+**Phase type**: chore (trust-surface hardening per D-043 — refines existing
+`orca node join --type proxmox` flow + existing TOFU `known_hosts` store; no
+new orchestration capability)
+
+### Wave 1 — Trust-surface foundations (security helpers + flag declarations)
+
+| Task ID | Owner | Wave | Must | Title | Files touched | Acceptance criterion |
+|---------|-------|------|------|-------|---------------|----------------------|
+| T02.1 | backend-engineer | 1 | Y | Add `security.SSHFingerprintSHA256` helper (AD-027) | `internal/security/sshkey.go` (extend) OR `internal/security/fingerprint.go` (extend) | Thin wrapper over `ssh.FingerprintSHA256(pubKey ssh.PublicKey) string` returning the canonical `SHA256:base64` string. Do NOT reuse `security.Fingerprint` (X.509 hex — different domain per RESEARCH §2.2). Unit test: known Ed25519 pub key → known `SHA256:` string. |
+| T02.2 | backend-engineer | 1 | Y | Export `security.WriteAtomic` (AD-029 enabler) | `internal/security/ca.go` | Rename `writeAtomic` → `WriteAtomic` (export) + update existing in-package callers. The `key-reset` atomic known_hosts rewrite (T02.7) needs it. Alternatively copy the ~20-LOC pattern into `proxmox` if export is undesirable — **recommend export** (RESEARCH §5 pitfall #10). `go build ./internal/security` PASS. |
+| T02.3 | backend-engineer | 1 | Y | Add `--host-key-fingerprint` flag on `orca node join` (D-044) | `internal/cli/node.go` | `nodeJoinCmd.Flags().StringVar(&joinHostKeyFP, "host-key-fingerprint", "", "SSH host key SHA256:base64 fingerprint (pre-pin; supersedes TOFU for --type proxmox)")` in the flag-registration block (node.go:344-354). Add `joinHostKeyFP string` to the var block (node.go:47-60). Validation in `RunE`: if `joinHostKeyFP != ""` and `--type != proxmox`, emit a clear error ("--host-key-fingerprint requires --type proxmox today"). Flag is generic for future SSH-joined kinds (D-044). |
+| T02.4 | backend-engineer | 1 | Y | Add `HostKeyFingerprint` field to `proxmox.Options` | `internal/proxmox/bootstrap.go` | Add `HostKeyFingerprint string` to the `Options` struct (bootstrap.go:55). Pass-through from `internal/cli/node.go` joinProxmox (node.go:158-166): `HostKeyFingerprint: joinHostKeyFP`. |
+
+### Wave 2 — Trust features + bugfix (build on Wave 1)
+
+| Task ID | Owner | Wave | Must | Title | Files touched | Acceptance criterion |
+|---------|-------|------|------|-------|---------------|----------------------|
+| T02.5 | backend-engineer | 2 | Y | Implement `pinnedHostKeyCallback` (REQ-058, AD-028) | `internal/proxmox/bootstrap.go` | `pinnedHostKeyCallback(expectedSHA256Base64 string) (ssh.HostKeyCallback, error)`: validate `SHA256:` prefix up front (reject raw hex with a clear error per D-045); callback receives server's `ssh.PublicKey`, computes `ssh.FingerprintSHA256(key)` (via T02.1 helper or inline), compares full strings to the operator-supplied value; returns `nil` on match, `error` on mismatch (fail closed). In `BootstrapProxmox`: if `opts.HostKeyFingerprint != ""` use `pinnedHostKeyCallback`, else fall back to the TOFU callback (T02.6). Unit test: match → callback returns nil; mismatch → returns error mentioning REQ-058; non-`SHA256:`-prefixed input → constructor returns error. |
+| T02.6 | backend-engineer | 2 | Y | **BUGFIX (v0.6 ship-defect)**: FIX the latent TOFU capture bug (RESEARCH §2.1, §5 pitfall #1, GRILL condition #1) | `internal/proxmox/bootstrap.go` | Wrap `knownhosts.New(...)` with a custom callback that: on `*knownhosts.KeyError{Want: []}` (host unknown) captures the server-presented `ssh.PublicKey`, writes a line via `knownhosts.Line([]string{knownhosts.Normalize(addr)}, key)` to `certpaths.KnownHostsPath()` using `security.WriteAtomic` (T02.2, AD-029), and returns `nil` (allow the dial to proceed). On `*knownhosts.KeyError{Want: [knownKey]}` (mismatch) returns the error (MITM detection). On `nil` (host present + match) returns `nil`. This fixes the v0.6 latent ship-defect where first-connect Proxmox join always failed (verified against `golang.org/x/crypto@v0.54.0/ssh/knownhosts/knownhosts.go:370-385`). P04 audit must record this as ship-defect closure. Unit test: first-connect captures the key + writes known_hosts; second-connect matches; mismatch-connect fails. |
+| T02.7 | backend-engineer | 2 | Y | Populate `Result.HostKeyFingerprint` (RESEARCH §2.2, §5 pitfall #2) | `internal/proxmox/bootstrap.go` | In the capture path (T02.6) and the pinned path (T02.5), set `Result.HostKeyFingerprint = ssh.FingerprintSHA256(hostKey)` (via T02.1). The field is currently declared (bootstrap.go:83-85) but always `""`. After T02.7, `orca node join --type proxmox` output includes the real fingerprint. Unit test: `Result.HostKeyFingerprint` is non-empty + `SHA256:`-prefixed after a successful bootstrap. |
+| T02.8 | backend-engineer | 2 | Y | Implement `orca node key-reset <node>` (REQ-059, D-046, AD-029) | `internal/cli/node.go`, `internal/proxmox/bootstrap.go` (new `ResetHostKey` helper OR inline in cli) | New `nodeKeyResetCmd` (`&cobra.Command{Use: "key-reset <node>", Args: cobra.ExactArgs(1), RunE: ...}`) registered via `nodeCmd.AddCommand(nodeKeyResetCmd)` (node.go:358-360). `RunE`: (1) resolve `<node>` arg via `nodeRegistry()` (node.go:37) → get node row → use `node.Name` (the host address for proxmox nodes) as the `known_hosts` match key; (2) call `proxmox.ResetHostKey(host) error` which reads `certpaths.KnownHostsPath()`, filters lines whose host field (before first whitespace, normalized via `knownhosts.Normalize`) matches, rewrites via `security.WriteAtomic` (T02.2); (3) audit-log `event=node.key_reset` with `actor`+`node`+`host` via `engine.Audit.Record`; (4) print `✓ Host key reset for <node> (next connect will re-pin via TOFU or --host-key-fingerprint)`. **Local only — do NOT revoke remote authorized_keys** (D-046). Unit test: known_hosts with 2 entries for the target host + 1 for another host → after reset, target's 2 lines removed, other host's line intact; audit row inserted. |
+| T02.9 | backend-engineer | 2 | Y | Apply the TOFU capture-fix to `doctor proxmox` probe (GRILL condition #2 — doctor parity with bootstrap) | `internal/doctor/doctor.go` | The doctor proxmox probe (doctor.go:412-415) uses the same `knownhosts.New(...)` callback pattern as bootstrap. Apply the same capture-fix wrapper (T02.6) so `doctor proxmox` on a first-connect node doesn't fail. **P02 is not complete until both bootstrap (T02.6) and doctor (T02.9) callbacks use the capture-fix wrapper — GRILL condition #2 binding parity check.** (If the doctor probe already relies on a prior `node join` having populated `known_hosts`, the fix is still correct — it makes the doctor robust to a missing entry.) |

+
+## Risk Register (carried forward from RESEARCH_v0.8.md §5)
+
+| # | Pitfall | Phase(s) affected | Mitigation |
+|---|---------|-------------------|------------|
+| 1 | TOFU capture is currently BROKEN: `knownhosts.New` returns `KeyError{Want:[]}` on first connect and does NOT auto-write; current `BootstrapProxmox` treats it as a dial failure. | P02 | T02.6 wraps the callback to capture-and-persist on `KeyError{Want:[]}` via `knownhosts.Line` + `security.WriteAtomic`. This is a v0.6 latent bug that P02 closes. |
+| 2 | `Result.HostKeyFingerprint` is declared but never populated (always `""`). D-045's rationale references "existing output" that doesn't exist. | P02 | T02.7 adds `ssh.FingerprintSHA256(hostKey)` computation in both the capture and pinned paths. 1-line addition once the host key is available. |
+| 3 | No `sessionRunner` seam in proxmox — testing the SSH command sequence without a real SSH server is impossible. | P01 | T01.1 adds a 1-interface ~10-LOC `sessionRunner` seam in Wave 1. Unlocks ~40% of proxmox coverage. Backward compatible. |
+| 4 | `internal/store/cert_repo.go` has NO test — v0.7 P01 REQ-053 was supposed to add `cert_repo_test.go` but it's missing (v0.7 leftover). | P01 | T01.7 adds `cert_repo_test.go` (Insert/Get/List/ListByNode/LatestForKind/PruneOlderThan/Delete + N=3 rotation). Directly lifts store coverage toward 70%. |
+| 5 | `internal/cli/daemon.go` starts a long-running mTLS server — testing it in cli requires a lifecycle harness; it's already covered by `internal/daemon/server_test.go`. | P01 | T01.6 excludes `daemon.go` from the cli 70% target; documents the exclusion in a test-file comment. Avoids double-testing. |
+| 6 | `cmd/orca` 50% toe-hold is low-value (15 LOC of glue; effort:coverage ratio is poor). | P01 | T01.11 keeps it at the 50% toe-hold per D-047; does NOT over-invest. A small `run() int` refactor enables a smoke test. |
+| 7 | `go: no such tool "covdata"` for zero-test packages — a Go toolchain quirk when a package has no test files; NOT a real 0% number. | P01 | T01.9, T01.10, T01.11 each add a `_test.go` file, which makes coverage computable. Don't treat the tooling error as a measurement. |
+| 8 | `transport.dispatchToPeer` has no seam — testing the remote-dispatch branch requires a new interface OR `httptest.NewTLSServer`. | P01 | T01.3 uses `httptest.NewTLSServer` (no refactor needed). T01.2 (conditional `peerDispatcher` seam) is only added if engine cannot otherwise hit 70%. |
+| 9 | `knownhosts.Line` + `knownhosts.Normalize` are the helpers for the TOFU-capture fix and `key-reset` matching. | P02 | T02.6 + T02.8 use `Normalize` to match host strings consistently (handles `host:22` vs `host`). |
+| 10 | `security.writeAtomic` is unexported (ca.go:305); `key-reset`'s atomic known_hosts rewrite needs it. | P02 | T02.2 exports `WriteAtomic` (recommended) OR copies the ~20-LOC pattern. Export is preferred — it's already used across ca.go + sshkey.go. |

+## v0.8 Scope Summary — Coverage & Trust Hardening
+
+v0.8 is a 3-execution-phase **NFR milestone** that continues the
+hardening theme opened by v0.7. v0.7 P03 (REQ-055) lifted four
+packages to ≥ 50%, but a coverage re-baseline after v0.7 ship shows
+the floor was insufficient: `internal/engine` regressed to 8.3%,
+`internal/proxmox` to 5.1%, and four more packages sit between 26% and
+48%. Three packages (`internal/audit`, `internal/certpaths`,
+`cmd/orca`) still have **no test files at all**. v0.8 also closes the
+two "future enhancement" hooks explicitly deferred in v0.6 — SSH
+host-key pre-pinning (D-035 caveat) and `orca node key-reset`
+(RESEARCH_v0.6 §80) — and adds a requirements-hygiene gate so the
+stale-REQ-status drift seen in REQUIREMENTS.md after v0.7 ship cannot
+recur:
+
+- **P01 — Coverage uplift round 2.** Raise six under-50% packages to
+  ≥ 70% and add first tests for the three zero-test packages. Covers
+  REQ-057.
+- **P02 — SSH trust hardening.** `--host-key-fingerprint` pre-pin flag
+  on `orca node join --type proxmox` + `orca node key-reset <node>`
+  command. Covers REQ-058, REQ-059.
+- **P03 — Requirements-hygiene gate.** `make verify-reqs` target +
+  verify-stage assertion that ROADMAP `Complete` ↔ REQUIREMENTS
+  `Complete`. Covers REQ-060.
+- **P04 — Final review + ship + audit.** Milestone release.
+
+The vision is unchanged. v0.8 is a hardening milestone, not a
+direction change. Milestone type: NFR (all phases are test/feat-chore
+on the trust surface — see CLARIFY D-043 for the `feat` vs `chore`
+classification of P02); the final phase's progressive patch IS the

+## v0.8 Clarified Decisions (D-series, full autonomy)
+
+The 5 v0.8 decisions (D-043..D-047) were auto-resolved at full autonomy
+within the `clarify_budget` (10):
+
+| ID | Question | Decision | Rationale | Confidence |
+|----|----------|----------|-----------|------------|
+| D-043 | Is P02 (SSH trust hardening) a `feat` phase or a `chore` phase? It adds a new flag + a new subcommand. | **`chore` (trust-surface hardening), not `feat`** | Both `--host-key-fingerprint` and `orca node key-reset` refine the *existing* `orca node join --type proxmox` flow and the existing TOFU `known_hosts` store (D-035). No new orchestration capability, no new node kind, no new API. They close a security gap explicitly deferred in v0.6, not open new surface area. Per `run.md` versioning logic this keeps v0.8 NFR (all phases fix/test/chore/perf/refactor). | 0.84 |
+| D-044 | Where does `--host-key-fingerprint` live — on `orca node join` or only on `--type proxmox`? | **On `orca node join` (root of the join subcommand), validated when `--type proxmox`** | The flag is generic (any future SSH-joined node kind will use it); gating it to `--type proxmox` only would require re-adding it later. Validation (`flag requires --type proxmox today`) happens in `RunE`, not in the flag declaration, so the flag is declared once on `node join` and the type check emits a clear error for non-proxmox types until other SSH-joined kinds exist. | 0.86 |
+| D-045 | `--host-key-fingerprint` format — raw hex, `sha256:`-prefixed, or OpenSSH `SHA256:base64`? | **OpenSSH `SHA256:base64` (the format `ssh-keyscan -E sha256 -D -` emits and operators expect)** | Matches the fingerprint format operators already see from `ssh-keyscan` and `orca node join`'s own `Result.HostKeyFingerprint` output. Accept only `SHA256:`-prefixed base64; reject raw hex with a clear error. Internally decode base64 → compare against `ssh.PublicKey` Marshal + sha256. | 0.88 |
+| D-046 | Does `orca node key-reset <node>` also revoke the orca pubkey on the remote host, or only clear the local `known_hosts` entry? | **Local `known_hosts` entry only** | Revoking the remote authorized_keys entry would orphan a working node (next dispatch would fail auth). `key-reset` is the local "forget this host's key" operation (mirrors `ssh-keygen -R host`); re-establishing trust is a separate `orca node join` re-run. Audit-log the reset with `actor`, `node`, `event=node.key_reset`. | 0.90 |
+| D-047 | Coverage target for P01 — 70% floor or higher? | **70% floor for the 6 under-50% packages; 50% floor for the 3 zero-test packages (`internal/audit`, `internal/certpaths`, `cmd/orca`) as a first-toe-hold** | 70% across the board for the already-tested packages matches D-042's "70% target for new packages" and is achievable without heroic mock effort. For the zero-test packages, going 0→50% is the realistic single-phase step (0→70% risks a coverage rathole on `cmd/orca` which is glue code); a future milestone can lift them to 70%. | 0.82 |

+| `cmd/orca` | **0%** (no test files) | ≥ 50% toe-hold | Same; `main.go` is 15 LOC of glue (`cli.Execute()` + error print) |
+
+**Coverage-floor achievability assessment (per package):**
+
+- **engine → 70% REALISTIC.** The package has clean seams: `LocalExecutor` interface (dispatcher.go:39), `PeerRegistry` is in-memory with `Add`/`Remove`/`All`/`Get` (peer.go), `Executor.Submit/Status` take a `*store.JobRepo`+`*store.TaskRepo` which can be backed by `:memory:`/temp-file sqlite via the existing `openTestDB` helper (node_repo_test.go:12). The `sshDialer` seam pattern (proxmox) has an analogue here: `transport.NewDispatchClient` is called inside `dispatchToPeer` (dispatcher.go:158) — to test dispatch-to-peer without a real mTLS server, either (a) inject a fake `DispatchClient` via a new interface seam, or (b) use `httptest.NewTLSServer` with a self-signed CA. Option (a) is lower-effort and aligns with the `LocalExecutor` pattern. Recommendation: extract a `peerDispatcher` interface (`Submit(ctx, spec, key) (*SubmitResponse, error)`) and inject it, OR test via `LocalSubmit`/`LocalStatus` paths (which only need a stubbed `LocalExecutor`) — the latter covers ~60% of dispatcher.go without a new seam. **Flag: 70% may require a small refactor to inject the dispatch client; 60-65% is achievable without one. Plan should decide whether to add the seam or accept 65%.**
+- **proxmox → 70% REALISTIC.** The `sshDialer` seam already exists (bootstrap.go:201-213, `sshDialerType` interface + `defaultSSHDialer` struct, overridable package-level var). A fake SSH dialer returning a mock `*ssh.Client` is the path. **However:** `*ssh.Client.NewSession()` + `session.CombinedOutput()` are concrete methods on the real `*ssh.Client` — there's no `sshSession` interface seam. To test `runRemote`/`deployPubKey`/`createLinuxUser`/`createPVERole`/etc. without a real SSH server, EITHER (a) introduce a `sessionRunner` interface seam (small refactor), OR (b) use `httptest.NewTLSServer` is wrong (it's SSH not HTTP) — instead use a real in-process SSH server via `golang.org/x/crypto/ssh` `NewServerConn` (more code but no new dep). **Flag: 70% likely requires either a `sessionRunner` interface refactor OR an in-process SSH server fixture. 50-55% is achievable with just the existing `sshDialer` seam + testing validation paths + `sudoersContent` string asserts (already done). Plan should add the `sessionRunner` seam — it's a 1-interface, ~10-LOC change that unlocks the bulk of the package.**
+- **cli → 70% AMBITIOUS but realistic.** The package is the largest (17 source files, ~2000 LOC). The existing tests use `rootCmd.SetArgs()` + `rootCmd.Execute()` + `t.TempDir()` + `ORCA_HOME` env (namespace_test.go:46-53 — `TestInitHonorsORCAHOME` is the template). The untested commands are `node join/leave/list`, `job run/list/stop/logs`, `cert *`, `doctor *`, `audit list`, `status`, `version`, `daemon`. Many touch the DB + certpaths + (for `node join --type proxmox`) the SSH dialer. **Strategy:** table-driven `rootCmd.Execute()` against a temp `ORCA_HOME` for each subcommand; mock the proxmox path via the existing `sshDialer` seam; capture stdout via `rootCmd.SetOut(&buf)`. **Flag: 70% across the whole package is a lot of test code; 55-65% is more realistic for one phase. The `daemon` command (background server) is hard to test without a lifecycle harness — recommend excluding it from the 70% target and documenting why.**
+- **transport → 70% REALISTIC.** `httptest.NewTLSServer` is the standard seam (already used in `internal/daemon/dispatch_test.go:59` and `server_test.go`). The `Dispatcher` interface (dispatch.go:49) is already mockable (`stubDispatcher` in dispatch_test.go:24 is the template). `MTLSClient.Do` wraps `http.Client.Do` — testable via `httptest.NewTLSServer` with a CA + client cert. `retry.go` `Do[T]` is generic + already partly tested via `idempotency_test.go` (TestRetrySucceedsAfterTransient etc.) — extend with backoff-timing asserts. `handshake_log.go` is pure slog calls — trivial to test by capturing into a `slog.Handler`. **No new seams needed; 70% achievable.**
+- **store → 70% REALISTIC.** The existing `openTestDB` helper (node_repo_test.go:12) + `withFastWatch` (job_task_repo_test.go:36) are reusable. **Critical gap:** `cert_repo.go` has NO test file despite v0.7 P01 REQ-053 claiming it was added — this is a v0.7 leftover bug. Adding `cert_repo_test.go` (Insert/Get/List/ListByNode/LatestForKind/PruneOlderThan/Delete + N=3 rotation history per REQ-025) alone lifts coverage significantly. Job/Task repo `Watch` is tested; `ListRecent`, error paths, scan-edge cases need coverage. **No new seams; 70% achievable.**
+- **jobspec → 70% REALISTIC.** `Parse` + `Validate` + `ParseFile` are pure functions over HCL bytes. Add golden-file HCL fixtures (multi-task, env vars, args) + error-path table (missing job, no tasks, missing command, malformed HCL, empty file, nonexistent file for `ParseFile`). `testdata/` dir doesn't exist yet — create it. **No new seams; 70% achievable, likely the easiest of the six.**
+- **audit → 50% toe-hold REALISTIC.** Package is 125 LOC, 4 exported funcs (`New`, `Emit`, `EmitWithErr`, `LogHandshakeOK`, `LogHandshakeFailed`, `FormatAction`, `Action.String`, `Result.String`). Strategy: construct `Audit` with a real `engine.Audit` backed by `:memory:` sqlite (via `store.NewAuditRepo` + `engine.NewAudit`) + assert rows in `audit_log` table; capture slog output via a test `slog.Handler`. **No new seams; 50% easily achievable, 70% achievable if desired.**
+- **certpaths → 50% toe-hold TRIVIAL.** Package is 64 LOC, pure path-join functions honoring `ORCA_HOME`/`ORCA_DB` env. Strategy: temp dir + `t.Setenv("ORCA_HOME", dir)` + assert each `*Path()` returns `filepath.Join(dir, <file>)`; test `ORCA_DB` override; test default-to-`~/.orca` fallback. Model the test on `namespace_test.go` (cli). **No new seams; 50%+ trivially achievable.**
+- **cmd/orca → 50% toe-hold REALISTIC but LOW VALUE.** `main.go` is 15 LOC: `cli.Execute()` + `fmt.Fprintf(os.Stderr, "error: %v")` + `os.Exit(1)`. The only testable behavior is "main() calls Execute and exits non-zero on error." A smoke test that calls `main()` in a subprocess (or refactors main into a `run() int` for testability) is the path. **Flag: 50% on a 15-LOC glue file is ~7 lines of covered code — the effort:coverage ratio is poor. D-047 explicitly called this out ("0→70% risks a coverage rathole on `cmd/orca` which is glue code"). Recommend the plan keep this at the 50% toe-hold and not over-invest.**
+
+### 1.2 Existing test-helper utilities (reuse, do NOT re-create)
+
+| Helper | Location | Reuse for |
+|--------|----------|-----------|
+| `openTestDB(t)` | `internal/store/node_repo_test.go:12` | engine, audit, store tests — returns `(*NodeRepo, func())` backed by temp-file sqlite; adapt to return `*sql.DB` for JobRepo/TaskRepo/AuditRepo/CapacityRepo/CertRepo |
+| `withFastWatch(t, d)` | `internal/store/job_task_repo_test.go:36` | store Watch tests — overrides `watchInterval` for deterministic ticks |
+| `initTestEnv(t)` | `internal/cli/init_test.go:17` | cli tests — sets `ORCA_HOME` to temp dir + returns cleanup |
+| `resetRootFlags(t)` | `internal/cli/namespace_test.go:13` | cli tests — resets `rootCmd` args/out/json/system flags between subtests |
+| `discardWriter` | `internal/cli/init_test.go:33` | cli tests — `io.Writer` that discards stdout |
+| `stubDispatcher` | `internal/daemon/dispatch_test.go:24` | transport/engine tests — implements `transport.Dispatcher` (`LocalSubmit`/`LocalStatus`); reusable as a `LocalExecutor` too since the signatures match |
+| `insertNode(t, repo, ctx, id, name)` | `internal/store/node_repo_test.go:217` | store/doctor tests — inserts a minimal node |
+| `security.CAInit`/`LoadCA`/`GenerateCSR`/`SignCSR`/`WriteCert`/`WriteKey` | `internal/security/ca.go` | transport mTLS tests — bootstrap a real CA + server cert into a temp dir (pattern in `doctor_test.go:69-94`) |
+| `t.Setenv("ORCA_HOME", dir)` + `t.Setenv("ORCA_DB", ...)` | `internal/doctor/doctor_test.go:23-24` | any test needing the orca namespace — preferred over manual `os.Setenv` (auto-cleanup) |
+
+### 1.3 Injected seams already present in the codebase (confirm by reading)
+
+1. **`sshDialer` (proxmox)** — `internal/proxmox/bootstrap.go:201-213`: package-level `var sshDialer sshDialerType = defaultSSHDialer{}`; interface `sshDialerType{ DialContext(ctx, network, addr, *ssh.ClientConfig) (*ssh.Client, error) }`. Tests can swap `sshDialer` for a fake. **GAP:** no `sessionRunner` seam — `runRemote` (line 217) calls `conn.NewSession()` + `session.CombinedOutput(cmd)` directly on the concrete `*ssh.Client`. Recommend P01 plan add a `sessionRunner` interface (`CombinedOutput(cmd) ([]byte, error)`) so `deployPubKey`/`createLinuxUser`/`createPVERole`/`createPVEUser`/`assignPVEACL`/`writeSudoers`/`validateSudoers` become testable without a real SSH endpoint.
+2. **`LocalExecutor` (engine dispatcher)** — `internal/engine/dispatcher.go:39`: interface `Submit(ctx, []byte) (string, error)` + `Status(ctx, string) (string, error)`. `Dispatcher` depends on it; tests inject a stub. **GAP:** `dispatchToPeer` (line 154) calls `transport.NewDispatchClient` directly (no seam) — to test the remote-dispatch branch, either add a `peerDispatcher` interface or test via `httptest.NewTLSServer`.
+3. **`PeerPersister` (engine peer)** — `internal/engine/peer.go:39`: optional persist callback; unused in production but available as a seam.
+4. **`Dispatcher` (transport)** — `internal/transport/dispatch.go:49`: `LocalSubmit`/`LocalStatus` interface; `stubDispatcher` in `daemon/dispatch_test.go:24` is the template stub.
+5. **`watchInterval` (store)** — `internal/store/job_task_repo.go:20`: unexported `var watchInterval = 1 * time.Second`; tests override via `withFastWatch`.
+
+### 1.4 Packages where 70% is unrealistic in a single phase (with evidence)
+
+- **`internal/cli` — 70% is ambitious.** 17 source files, ~2000 LOC. The `daemon` command (`internal/cli/daemon.go`) starts a long-running mTLS server — testing it requires a lifecycle harness (start, probe, shutdown) and is better covered by `internal/daemon/server_test.go` (already exists, 150 LOC). Recommend the P01 plan **exclude `daemon.go` from the cli 70% target** (document it as covered by the daemon package's own tests) and aim for 70% of the *remaining* cli files. Even so, 55-65% is the realistic single-phase outcome for the rest.
+- **`cmd/orca` — 70% is explicitly out of scope per D-047.** 15 LOC of glue; 50% toe-hold is the right call.
+- **`internal/proxmox` — 70% likely requires the `sessionRunner` seam refactor.** Without it, only the validation paths + `sudoersContent` string asserts are testable (~50-55%). The plan should add the seam; with it, 70% is achievable.
+

+
+## 2. SSH trust hardening research (P02 — REQ-058, REQ-059)
+
+### 2.1 Current TOFU `knownhosts.New()` callback — how it works
+
+**Location:** `internal/proxmox/bootstrap.go:125-128` (bootstrap) + `internal/doctor/doctor.go:412-415` (doctor proxmox probe).
+
+```go
+hostKeyCallback, err := knownhosts.New(certpaths.KnownHostsPath())
+// ...
+sshConfig := &ssh.ClientConfig{
+    HostKeyCallback: hostKeyCallback,
+    // ...
+}
+```
+
+**Mechanism (`golang.org/x/crypto/ssh/knownhosts`):**
+- `knownhosts.New(files ...string)` returns an `ssh.HostKeyCallback` that reads the OpenSSH-format `known_hosts` file at `certpaths.KnownHostsPath()` (= `$ORCA_HOME/known_hosts`, see `internal/certpaths/certpaths.go:62`).
+- **First connect (host absent from file):** the callback returns a `*knownhosts.KeyError` with `Want: []` (empty). This is a "host unknown" signal. **IMPORTANT:** `knownhosts.New` does NOT auto-write the key on first connect — it returns an error. The current orca code at `bootstrap.go:140` treats ANY dial error as a failure (`return nil, fmt.Errorf("ssh dial %s: %w", sshAddr, err)`). **This means the current TOFU flow is INCOMPLETE:** on a truly first connect, `knownhosts.New` returns `KeyError{Want:[]}` and the dial fails — there is no capture-and-persist step. The v0.6 RESEARCH_v0.6.md §A.5 claimed `knownhosts.New` "handles both capture and verify in one callback" but the actual `golang.org/x/crypto` API does NOT auto-capture; it only verifies. **This is a latent bug OR the operator is expected to pre-populate `known_hosts` manually (which contradicts the TOFU UX).** P02 must address this: either (a) wrap `knownhosts.New` with a custom callback that captures on `KeyError{Want:[]}` and writes via `knownhosts.Line`, or (b) accept that `--host-key-fingerprint` (REQ-058) becomes the *required* path for first connect and TOFU capture is a separate enhancement. **Flag for plan: the current TOFU capture is broken; P02 should fix it as part of the trust-hardening work (the `--host-key-fingerprint` path is actually simpler than TOFU because it doesn't need capture).**
+- **Subsequent connects (host present, key matches):** callback returns `nil` → dial proceeds.
+- **Subsequent connects (host present, key MISMATCH):** callback returns `*knownhosts.KeyError{Want: [knownKey]}` → dial fails with a clear error. This is the MITM-detection path.
+
+**File format:** OpenSSH `known_hosts` — one line per host: `[host]:port ssh-key-type base64-key` (or hashed-host form via `knownhosts.HashHostname`). `knownhosts.Line(addresses []string, key ssh.PublicKey) string` produces the line; `knownhosts.Normalize(address)` normalizes the host:port.
+
+### 2.2 `Result.HostKeyFingerprint` — current computation (CRITICAL FINDING)
+
+**Location:** `internal/proxmox/bootstrap.go:83-85` (field declaration) + `bootstrap.go:195-198` (return statement).
+
+```go
+type Result struct {
+    NodeName           string
+    NodeAddress        string
+    HostKeyFingerprint string  // field EXISTS
+}
+// ...
+return &Result{
+    NodeName:    opts.Host,
+    NodeAddress: opts.Host + ":8443",
+    // HostKeyFingerprint is NOT SET — always empty string
+}, nil
+```
+
+**Finding:** `Result.HostKeyFingerprint` is **declared but never populated**. The current `BootstrapProxmox` returns it as `""`. There is **no fingerprint computation today** — no `ssh.FingerprintSHA256` call, no hex digest, nothing. D-045's rationale ("matches the fingerprint format operators already see from `orca node join`'s own `Result.HostKeyFingerprint` output") is based on a field that is currently always empty.
+
+**Implication for P02:** The plan must ADD the fingerprint computation. The correct function is `ssh.FingerprintSHA256(pubKey ssh.PublicKey) string` (verified via `go doc`), which returns the **OpenSSH `SHA256:base64` format** (unpadded base64, exactly what `ssh-keyscan -E sha256` emits and what D-045 specifies). So D-045's format choice is correct *by intent* but the code doesn't produce it yet — P02 populates `Result.HostKeyFingerprint = ssh.FingerprintSHA256(hostKey)` during the capture path, and `--host-key-fingerprint` compares against `ssh.FingerprintSHA256` of the server-presented key.
+
+**No existing fingerprint-comparison utility in `internal/security/`.** `security.Fingerprint` (fingerprint.go:17) computes SHA-256 **hex** of an X.509 cert's DER — a DIFFERENT format (hex, not base64; X.509, not SSH). `security.FingerprintOf` (fingerprint.go:34) is the same. **Do NOT reuse these for SSH host-key comparison** — they're for the mTLS CA pin (`--ca-fingerprint`). P02 needs a new SSH-specific helper, e.g. `security.SSHFingerprintSHA256(pubKey ssh.PublicKey) string` (thin wrapper over `ssh.FingerprintSHA256`) or inline in `proxmox/bootstrap.go`.
+
+### 2.3 Where `--host-key-fingerprint` plugs in (REQ-058)
+
+**CLI seam:** `internal/cli/node.go:344-354` — the `init()` registers flags on `nodeJoinCmd`. Add:
+```go
+nodeJoinCmd.Flags().StringVar(&joinHostKeyFP, "host-key-fingerprint", "", "SSH host key SHA256:base64 fingerprint (pre-pin; supersedes TOFU for --type proxmox)")
+```
+Per D-044, the flag lives on `orca node join` (not just `--type proxmox`); validation in `RunE` (`node.go:78-83`) emits a clear error if the flag is set for a non-proxmox type.
+
+**Transport seam:** `internal/proxmox/bootstrap.go:131-136` — `ssh.ClientConfig.HostKeyCallback`. Currently `knownhosts.New(...)`. When `--host-key-fingerprint` is supplied, replace the callback with a `ssh.FixedHostKey`-style verifier that:
+1. Parses the operator-supplied `SHA256:base64` string (strip `SHA256:` prefix, base64-decode → 32 bytes).
+2. In the callback, receives the server's `ssh.PublicKey`, computes `ssh.FingerprintSHA256(key)`, compares to the operator string.
+3. Returns `nil` on match, `error` on mismatch (fail closed).
+
+**Recommended callback shape (concrete):**
+```go
+func pinnedHostKeyCallback(expectedSHA256Base64 string) (ssh.HostKeyCallback, error) {
+    // Validate format: must start with "SHA256:".
+    if !strings.HasPrefix(expectedSHA256Base64, "SHA256:") {
+        return nil, fmt.Errorf("host-key-fingerprint: must be OpenSSH SHA256:base64 format (got %q)", expectedSHA256Base64)
+    }
+    expected := expectedSHA256Base64 // store full string for direct compare
+    return func(_ string, _ net.Addr, key ssh.PublicKey) error {
+        got := ssh.FingerprintSHA256(key)
+        if got != expected {
+            return fmt.Errorf("host key fingerprint mismatch: got %s, want %s — refusing to connect (REQ-058)", got, expected)
+        }
+        return nil
+    }, nil
+}
+```
+**Why compare full strings (not base64-decoded bytes):** `ssh.FingerprintSHA256` returns the canonical `SHA256:base64` string; comparing it directly to the operator-supplied string is simplest and avoids a base64-decode step. Reject non-`SHA256:`-prefixed input up front with a clear error (D-045: "Accept only `SHA256:`-prefixed base64; reject raw hex with a clear error").
+
+**Pass-through to proxmox:** `internal/cli/node.go:158-166` — add `HostKeyFingerprint string` to `proxmox.Options` (bootstrap.go:55) and pass `joinHostKeyFP` through. `BootstrapProxmox` selects the callback: if `opts.HostKeyFingerprint != ""` use `pinnedHostKeyCallback`, else fall back to the TOFU `knownhosts.New` (with the capture-fix from §2.1).
+
+### 2.4 `orca node key-reset <node>` (REQ-059, D-046 — local known_hosts only)
+
+**Scope (D-046):** clear the local `~/.orca/known_hosts` entry for the node ONLY; do NOT revoke the remote authorized_keys entry (would orphan a working node). Audit-log `event=node.key_reset` with `actor` + `node`.
+
+**`known_hosts` line format written by `golang.org/x/crypto/ssh/knownhosts`:**
+- `knownhosts.Line(addresses []string, key ssh.PublicKey) string` → `"[host]:port ssh-ed25519 AAAA...\n"` (or `host ssh-ed25519 AAAA...` if port 22 — `knownhosts.Normalize` handles the `:22` vs bare-host normalization).
+- The file is plain text, one entry per line, `#`-prefixed comments allowed.
+
+**No library function to remove a host's entries.** `knownhosts.New` only reads. The reset must be implemented manually:
+1. Read `certpaths.KnownHostsPath()` (`internal/certpaths/certpaths.go:62`).
+2. Filter lines: keep lines whose host field (before the first whitespace) does NOT match `knownhosts.Normalize(nodeName)` (or the node's address). **Edge:** a host may have multiple entries (one per key type); remove all matching lines.
+3. Write the filtered content back via **atomic rewrite** (temp file in same dir + `os.Rename`) — reuse `security.writeAtomic` (ca.go:305) OR implement inline (it's unexported in `security`; either export it or copy the ~20-LOC pattern). **Recommend atomic rewrite, NOT in-place truncation** — in-place rewrite via `os.OpenFile(O_TRUNC|O_WRONLY)` risks data loss on crash mid-write.
+
+**CLI registration seam:** `internal/cli/node.go:358-360` — the `init()` does `nodeCmd.AddCommand(nodeJoinCmd)`, `nodeLeaveCmd`, `nodeListCmd`. Add:
+```go
+nodeCmd.AddCommand(nodeKeyResetCmd)
+```
+where `nodeKeyResetCmd` is a new `&cobra.Command{Use: "key-reset <node>", Args: cobra.ExactArgs(1), RunE: ...}`. The `RunE`:
+1. Resolve `<node>` arg → look up the node in the registry (`nodeRegistry()` at node.go:37) to get its address (for matching `known_hosts` lines) — OR accept the raw host string directly. **Recommend:** accept the node NAME (consistent with `doctor proxmox` which iterates `node.Name`), look up the node row, use `node.Name` (which is the host address for proxmox nodes per `bootstrap.go:196`) as the `known_hosts` match key.
+2. Call a new `proxmox.ResetHostKey(host string) error` (or inline in cli) that does the atomic rewrite.
+3. Audit-log via `engine.Audit.Record(ctx, "cli", "node.key_reset", nodeID, "success", nil, map[string]any{"host": host})`.
+4. Print `✓ Host key reset for <node> (next connect will re-pin via TOFU or --host-key-fingerprint)`.
+
+**Reusability:** the `nodeRegistry()` helper (node.go:37) + `openDB()` (node.go:25) + `newLogger()` (node.go:33) are all available for the key-reset command.
+

+## 3. Requirements-hygiene gate research (P03 — REQ-060)
+
+### 3.1 Current Makefile targets
+
+`Makefile` has 11 targets: `build`, `test`, `test-race`, `lint`, `fmt`, `clean`, `run`, `version`, `changelog`, `release`, `security-scan` (Makefile:1-100). **No `verify-reqs` target exists.** The `.PHONY` list at line 1 must be extended.
+
+### 3.2 Current `.coreci.yml` pipeline structure
+
+4 pipelines (`.coreci.yml:19-134`):
+- **validate** (line 20): 4 steps — `go-version` (gofmt+vet), `gosec`, `govulncheck`, `gitleaks`.
+- **build** (line 53): 1 step — version-injected `go build`.
+- **test** (line 72): 1 step — `go test -race -coverprofile=coverage.out ./...` + `go tool cover -func | tail -1`.
+- **release** (line 81): gated on `refs/tags/v*`; 3 steps — build-artifact, gitea-release, container-publish.
+
+**Hook for `verify-reqs`:** add a 5th step to the `validate` pipeline (after `go-version`, before/after `gosec`) OR add it to the `test` pipeline. **Recommend `validate` pipeline** — requirements hygiene is a static check (no test run needed), belongs alongside gofmt/vet/lint. Step shape:
+```yaml
+- name: verify-reqs
+  image: golang:1.25
+  commands:
+    - make verify-reqs
+```
+
+### 3.3 `verify-reqs` implementation recommendation
+
+**Assertion (REQ-060):** every REQ row in `ROADMAP.md` marked `[x]`/Complete must have a matching REQ-ID row in `REQUIREMENTS.md` with `Complete` status. (Reverse direction — every REQUIREMENTS `Complete` has a ROADMAP `[x]` — is also worth checking but the drift that motivated this was ROADMAP-shipped-but-REQUIREMENTS-Pending, so the forward direction is the priority.)
+
+**Approach: small Go program in `cmd/verify-reqs` OR a shell+awk script?**
+
+- **Go program** (~80 LOC): parse both markdown tables with `regexp`, build two `map[string]string` (REQ-ID → status), diff. Pros: type-safe, testable, consistent with the Go toolchain; can be a `cmd/verify-reqs/main.go` with its own `_test.go`. Cons: adds a binary target.
+- **Shell+awk** (~30 LOC): `awk` over the markdown tables. Pros: no new Go package; minimal. Cons: fragile parsing, hard to test, shell-quoting issues.
+
+**Recommendation: Go program at `cmd/verify-reqs/main.go`.** Reasons: (1) testable with golden-file fixtures (parse a sample ROADMAP+REQUIREMENTS pair, assert diff); (2) consistent with the project's Go-only tooling ethos (no shell-awk fragility); (3) the `make verify-reqs` target just calls `go run ./cmd/verify-reqs`; (4) CoreCI's `golang:1.25` image has `go` available — no extra dep.
+
+**Parsing approach (concrete):**
+1. ROADMAP.md: regex `^\s*-\s*\[(x|X| )\]\s*Phase.*—.*tag` is NOT the right pattern (that's phase lines, not REQ rows). The REQ coverage is in per-phase bullet lists under "### Per-phase REQ coverage" (ROADMAP.md:161-180) AND in the milestone section bodies. **Simpler:** the ROADMAP uses `- [x] Phase N: ...` for completed phases. The authoritative REQ↔status mapping lives in **REQUIREMENTS.md** (the single table at lines 9-56 + per-milestone tables at 103-142). **Re-interpret REQ-060:** the assertion is really "ROADMAP milestone sections marked COMPLETE ↔ REQUIREMENTS rows for that milestone marked Complete." The drift was: v0.7 ROADMAP said "COMPLETE" (line 116) but REQUIREMENTS v0.7 rows (REQ-053..056) were "Pending" (now corrected to "Complete" in SPECIFY).
+2. **Refined assertion:** parse REQUIREMENTS.md table rows (`| REQ-XXX | ... | ... | ... | **Complete** |` or `| Pending |`); for each REQ-ID, record status. Then parse ROADMAP.md for milestone-level "COMPLETE" markers (`## Milestone v0.X: ... — **COMPLETE**`) AND phase-level `- [x]` markers. For each milestone marked COMPLETE in ROADMAP, assert every REQ-ID belonging to that milestone (per the REQUIREMENTS milestone column) is `Complete` in REQUIREMENTS. **OR (simpler, matches the SPECIFY wording):** for every REQ-ID in REQUIREMENTS.md whose `Phase` column references a milestone that ROADMAP marks COMPLETE, the Status must be `Complete`. This catches the exact drift (ROADMAP-shipped, REQUIREMENTS-stale).
+
+**Concrete regex:**
+- REQUIREMENTS row: `^\|\s*(REQ-\d+)\s*\|.*?\|\s*\*\*(Complete|Pending)\*\*\s*\|` (capture ID + status).
+- ROADMAP milestone-complete: `^##\s*Milestone\s+v0\.\d+:.*—\s*\*\*COMPLETE\*\*` (capture milestone label).
+- Map milestone → REQs via the REQUIREMENTS `Phase` column (e.g. `v0.7 P1` → milestone `v0.7`).
+
+**Where it hooks in:** `make verify-reqs` runs `go run ./cmd/verify-reqs .ciagent/ROADMAP.md .ciagent/REQUIREMENTS.md`; `.coreci.yml` validate pipeline adds the step. Exit 0 on consistency, exit 1 with a diff listing on drift.
+
+### 3.4 The drift that motivated REQ-060
+
+After v0.7 ship, REQUIREMENTS.md rows REQ-053..056 were "Pending" despite ROADMAP.md marking milestone v0.7 COMPLETE and all phases `[x]`. This was corrected during v0.8 SPECIFY (the rows now read `**Complete**`). REQ-060 ensures the drift cannot recur: the CI validate pipeline fails if ROADMAP says COMPLETE but REQUIREMENTS says Pending.

+## 4. Architectural decisions surfaced (AD-027..AD-030)
+
+| ID | Decision | Rationale |
+|----|----------|-----------|
+| AD-027 | `ssh.FingerprintSHA256` (OpenSSH `SHA256:base64`) as the SSH host-key fingerprint format | Matches D-045 + `ssh-keyscan -E sha256` output. The existing `security.Fingerprint` (hex, X.509) is NOT reused — different domain. P02 adds a thin SSH-specific helper. |
+| AD-028 | `--host-key-fingerprint` callback compares full `SHA256:base64` strings, not decoded bytes | `ssh.FingerprintSHA256` returns the canonical string; direct string compare avoids a base64-decode step and is less error-prone. Validate `SHA256:` prefix up front. |
+| AD-029 | `orca node key-reset` rewrites `known_hosts` via atomic temp-file + rename | Prevents data loss on crash mid-write. Reuse the `writeAtomic` pattern from `security/ca.go:305` (export it or copy the ~20 LOC). |
+| AD-030 | `verify-reqs` implemented as `cmd/verify-reqs/main.go` (Go program), not shell+awk | Testable, type-safe, consistent with Go-only tooling. `make verify-reqs` runs `go run ./cmd/verify-reqs`. Hooked into `.coreci.yml` validate pipeline. |
+
+---
+
+## 5. Pitfalls, gaps, and flags for the plan
+
+1. **TOFU capture is currently BROKEN (§2.1).** `knownhosts.New` returns `KeyError{Want:[]}` on first connect and does NOT auto-write the key. The current `BootstrapProxmox` treats this as a dial failure. P02 must either (a) wrap the callback to capture-and-persist on `KeyError{Want:[]}` via `knownhosts.Line` + atomic write, or (b) make `--host-key-fingerprint` the required first-connect path. **Recommend (a) — fix TOFU + add pre-pin as superset.** This is a v0.6 latent bug that P02 closes.
+2. **`Result.HostKeyFingerprint` is never populated (§2.2).** D-045's rationale references "existing output" that doesn't exist. P02 must ADD the computation (`ssh.FingerprintSHA256`). Low risk — it's a 1-line addition once the host key is available.
+3. **No `sessionRunner` seam in proxmox (§1.3).** Testing the SSH command sequence (deployPubKey, createLinuxUser, pveum, sudoers, visudo) without a real SSH server requires a new interface seam. **Recommend P01 plan add it** — 1 interface, ~10 LOC, unlocks ~40% of proxmox coverage.
+4. **`internal/store/cert_repo.go` has NO test (§1.1).** v0.7 P01 REQ-053 was supposed to add `cert_repo_test.go` but it's missing — `internal/store/` glob shows no `cert_repo_test.go`. This is a v0.7 leftover. P01 should add it (it directly lifts store coverage toward 70%).
+5. **`internal/cli/daemon.go` excluded from cli 70% target (§1.4).** The daemon command starts a long-running server; it's covered by `internal/daemon/server_test.go` (150 LOC). Don't double-test in cli.
+6. **`cmd/orca` 50% toe-hold is low-value (§1.1).** 15 LOC of glue; the test effort:coverage ratio is poor. D-047 already called this out. Don't over-invest.
+7. **`go: no such tool "covdata"` for zero-test packages (§1.1).** This is a Go toolchain quirk when a package has no test files — `go test -cover` can't compute coverage without a test binary. It's NOT a real 0% number (it's "undefined"). Adding any `_test.go` file makes the number computable. Don't treat the error as a coverage measurement.
+8. **`transport.dispatchToPeer` has no seam (§1.3).** Testing the remote-dispatch branch of `Dispatcher.Submit` requires either a new `peerDispatcher` interface OR `httptest.NewTLSServer`. The latter is already used in `daemon/dispatch_test.go`; recommend the plan use `httptest.NewTLSServer` (no refactor needed) for transport coverage.
+9. **`knownhosts.Line` + `knownhosts.Normalize` are the helpers for the TOFU-capture fix and for `key-reset` matching (§2.1, §2.4).** Use `Normalize` to match host strings consistently (handles `host:22` vs `host`).
+10. **`security.writeAtomic` is unexported (ca.go:305).** `key-reset`'s atomic known_hosts rewrite needs it. Either export `WriteAtomic` from `security`, or copy the ~20-LOC pattern into `proxmox`/`cli`. **Recommend export** — it's already used across ca.go + sshkey.go and is generally useful.
+

+
+## 6. Dependencies
+
+v0.8 adds **zero** new direct dependencies:
+- SSH host-key fingerprint: `ssh.FingerprintSHA256` (already in `golang.org/x/crypto/ssh` v0.54.0, direct dep since v0.6).
+- `knownhosts.Line`/`Normalize`/`KeyError`: same `golang.org/x/crypto` module.
+- `verify-reqs`: stdlib only (`regexp`, `os`, `fmt`).
+- Tests: `net/http/httptest` (stdlib), existing interfaces.
+
+`go.mod` is unchanged by v0.8.
+
+---
+
+## 7. PERSONAS assessment (v0.8)
+
+v0.8 is an NFR milestone touching tests (9 packages), SSH trust surface (proxmox + cli/node + security), and a requirements-hygiene Go program. The 3-persona roster from config.json (lead-developer, backend-engineer, data-engineer) is sufficient — no phase-specific personas needed.
+
+**Roster confirmation:**
+- **lead-developer** — owns coordination + `cmd/orca` smoke test + `internal/cli` coverage (cert/doctor/audit/status/version subcommands) + the `verify-reqs` Go program (coordination territory).
+- **backend-engineer** — owns `internal/transport` tests (httptest.NewTLSServer) + `internal/engine` tests (LocalExecutor stubs, PeerRegistry) + SSH trust-surface in `internal/proxmox/bootstrap.go` (pinned callback, TOFU capture fix, sessionRunner seam) + `internal/cli/node.go` (`--host-key-fingerprint` flag, `key-reset` subcommand).
+- **data-engineer** — owns `internal/store` tests (cert_repo_test.go gap + coverage uplift) + `internal/audit` tests (sqlite-backed audit_log asserts) + `internal/certpaths` tests (path-join asserts) + `internal/jobspec` tests (golden HCL fixtures).
+
+No frontend persona (no UI). No devops persona (no packaging/distribution — `verify-reqs` is a Go program, not a CI config change; the `.coreci.yml` edit is a 3-line hook, lead-developer territory). No security-engineer persona (the SSH trust work is backend-engineer territory — the security-engineer was deactivated in v0.7 and v0.8 doesn't re-add it; the trust-surface hardening is a refinement of the existing `proxmox` package, not new security architecture).
+
+See `.ciagent/PERSONAS.md` (updated with v0.8 YAML frontmatter + territory globs matching the actual file structure).
