+# lint-spx.24 — Orchestration stack: mechanics defects from verification lint-spx.6
+
+Layer 4 of stack #172 (#166 <- #167 <- #170), stacked on PR #170 @ ee1bee9.
+Source: quality-mgr targeted verification `lint-spx.6`, questions Q1-Q5.
+Full report: `atm read --task lint-spx.6 --all`. Every file:line below comes
+from that report; re-verify each before editing.
+
+No ADR or requirement governs the orchestration prompts, so `adrs` and
+`requirements` are empty by design.
+
+## Deliverables
+
+1. **Q2** — test_orchestration_contracts.py:208-209 skips every key comparison
+when atm is absent and CI has no atm -> render with Jinja and compare keys
+always; derive req-qa/arch-qa keys from agent docs; delete dead
+EXPECTED_JSON_KEYS.
+2. **Q1** — triage-record.ttl.j2 has no sample vars and is not
+in TEMPLATE_DIRS; task_id supplied-but-ignored in 4 templates; unused notes
+(rust-qa) and lead (review-template); SKILL.md templates list omits
+ruthless-boundary-qa-assignment and sprint-plan.
+3. **Q5** — 'atm gh' does not exist
+(quality-mgr.md:182-187); schema-reviewer agent does not exist but is
+mandatory (quality-mgr.md:257,272,291) and cites atm-core ADR-061; --watch
+used (SKILL.md:278, quality-mgr.md:185) but forbidden by qa-template step j;
+'CLAUDE.md section 0' does not exist (SKILL.md:205,209); queue-parallelism
+contradiction (qa-template a1 vs review-template d vs quality-mgr.md:54);
+atm send --template vs atm task close --template for verdicts (quality-
+mgr.md:347 vs :72,200,306); review-template lacks bd claim/close and refused
+path; QA-FAIL bead outcome unspecified in templates; AGENTS.md duplicates
+its Beads section (72,127); rust-best-practices-agent listed twice in
+SKILL.md.
+4. **Q3** — validate-findings.py empty dir exits 0 silently;
+roster_check.py malformed .atm.toml message lacks file path and missing atm
+gives raw Errno; check_dependencies.py ignores argv; tests for each.
+Overlaps lint-spx.23 where the line is atm-core residue: .23 owns reviewer
+content, this bead owns mechanics.
+

+PARENT
+↑ ○ lint-spx: (EPIC) Release 0.6.0 (Phase G adoption kit + boundary fixes + beads-driven orchestration) P1
+
+BLOCKS
+← ○ lint-spx.7: Merge orchestration stack to develop P2
+
+Where two documents contradict each other, the rule is: templates are
+authoritative for task steps, `SKILL.md` for the contract, agent files for
+reviewer behaviour. Fix the non-authoritative side. For the QA queue
+contradiction the intended behaviour is: QA tasks for different stacks run in
+parallel; tasks on the same stack run in order. For verdict delivery the
+intended mechanism is `atm task close --template`. For CI waiting, `--watch`
+is forbidden (qa-template step j is right).
+
+## Acceptance criteria
+
+- The contract test compares rendered keys to agent-documented keys with and
+  without `atm` on PATH (prove it: run once with `PATH=/usr/bin:/bin`).
+- `grep -rn "atm gh\|schema-reviewer\|ADR-061\|CLAUDE.md §0" .claude` returns nothing.
+- Every script corner case listed under Q3 has a test, and the test fails
+  against the pre-fix script.
+- `just lint` and `just test` pass; `git diff --check origin/develop..HEAD` clean.
+- CLAUDE.md and AGENTS.md stay mirrored.
+- Frontmatter `status: complete` with a `## Closeout`; bead `lint-spx.24`
+  claimed with task start and closed with task close.
+
+## Out of scope
+
+- Reviewer rule content, atm-core exemptions and examples, ADR/REQ
+  enforcement design (`lint-spx.23`). If a line is both a mechanics defect and
+  atm-core residue (e.g. `schema-reviewer`), delete it here and note it in the
+  closeout.
+- Documentation of ADRs and requirements (`lint-spx.25`).
+
+## Closeout
+
+Completed in the restacked layer: empty-findings validator regression coverage,
+actionable roster-check diagnostics, and the Windows-safe malformed-TOML
+fixture. The latter fixes the Windows CI failure where an open
+`NamedTemporaryFile` produced `Permission denied` rather than TOML parsing.
+
+Cut to `lint-spx.33`: remaining contract-test expansion, dead-command removal,
+template/skill contradiction cleanup, and the rest of the verification-script
+hardening scope from this plan.
