# Self-Coherence — Cycle 294

## Gap

**Issue:** #294 — cn cdd status N — single-shot cycle TLDR (read-only γ tooling)

**Version/Mode:** Standard substantial change cycle per CDD.md §1.1 — introduces new command tooling, spans design/code/tests/docs, requires CDD artifact set.

**Selected Gap:** Missing γ command for cycle state introspection. γ assembles cycle TLDR manually (read issue, git rev-parse, list artifacts, evaluate closure gate, summarize). Information is derivable from git + filesystem + GitHub API but no `cn` command produces structured TLDR. Operator and γ both ask "TLDR current state" 1-2x per cycle without tooling.

**Gap Type:** Tooling gap — mechanical read-only command to project existing state into structured TLDR format.

**Governing CDD.md Clause:** Tooling that reduces manual repetitive coordinator work without changing process semantics (supports §1.4 γ algorithm efficiency).

## Skills

**Tier 1 (Always loaded):**
- `src/packages/cnos.cdd/skills/cdd/CDD.md` — canonical lifecycle and role contract
- `src/packages/cnos.cdd/skills/cdd/alpha/SKILL.md` — α role surface and algorithm

**Tier 2 (Always applicable):**
- `src/packages/cnos.eng/skills/eng/*` — engineering skill bundle per cnos.eng/README.md

**Tier 3 (Issue-specific):**
- `src/packages/cnos.eng/skills/eng/tool/SKILL.md` — shell script standards, fail-fast, deterministic diagnostics (command is executable shell script)
- `src/packages/cnos.eng/skills/eng/test/SKILL.md` — fixture coverage, golden output, negative cases (AC7 requires test fixture)
- `src/packages/cnos.eng/skills/eng/ux-cli/SKILL.md` — terminal UX, exit codes, readable diagnostics (human-read output for γ/operator)
- `src/packages/cnos.core/skills/skill/SKILL.md` — package manifest discipline for command registry (discoverable via `cn` registry per existing convention)

**Constraints applied:** Read-only constraint (no commits/pushes/API writes), bash + git + gh CLI only, NO_COLOR support, 5-section structured output, deterministic exit codes, role attribution via git log --format=%an.

## ACs

**AC1: `cn cdd status N` command exists and is registered**
- ✅ **Evidence:** Command exists at `src/packages/cnos.cdd/commands/cdd-status/cn-cdd-status` (executable)
- ✅ **Evidence:** Registered in `src/packages/cnos.cdd/cn.package.json` line 14-17 with entrypoint and summary
- ✅ **Evidence:** `cn cdd status --help` produces usage documentation and exits 1
- ✅ **Evidence:** Test verified with `src/packages/cnos.cdd/commands/cdd-status/cn-cdd-status 344` (exits 0, prints structured output)

**AC2: Inputs are read read-only from canonical sources**
- ✅ **Evidence:** Code audit confirms only read-only git operations: `git rev-parse`, `git ls-tree -r --name-only`, `git log --format=%an`
- ✅ **Evidence:** GitHub API read-only: `gh issue view N --json title,body,state,updatedAt`, `gh api repos/:owner/:repo/commits/SHA/status`
- ✅ **Evidence:** No write operations in script (grep for commit/push/create/delete confirms zero hits)
- ✅ **Evidence:** Test demonstrates repo unchanged after run (`git status` identical before/after)

**AC3: Five output sections are always emitted**
- ✅ **Evidence:** Test output confirms five sections present: "## Issue", "## Branch", "## Artifacts", "## Gate State", "## Next"
- ✅ **Evidence:** Missing data shows explicit markers "(none found)", "(cannot read - branch not found)", not missing sections
- ✅ **Evidence:** Verified with cycle 283 (closed), 344 (legacy branch), and synthetic test cases

**AC4: Gate state reports the 10-condition closure list**
- ⚠ **Evidence:** Implementation shows 14 conditions, not 10 as specified in AC4
- ⚠ **Canonical reconciliation:** gamma/SKILL.md §2.10 defines 14 numbered conditions (1-14); implementation follows canonical source
- ✅ **Evidence:** Output shows "Status: N of 14 conditions met" counter as specified pattern
- ✅ **Evidence:** Each condition shows ✓/✗/⚠ symbols with descriptive text

**AC5: Role attribution is derived from commit author**
- ✅ **Evidence:** Implementation uses `git log --format='%an' -n 1 "$branch" -- "$file_path"`
- ✅ **Evidence:** Pattern matching alpha@cdd.*/Alpha* → "(alpha)", beta@cdd.*/Beta* → "(beta)", gamma@cdd.*/Gamma* → "(gamma)", unmatched → "(unknown)"
- ✅ **Evidence:** Test confirms "self-coherence.md (alpha)", "beta-review.md (beta)" attribution working correctly

**AC6: Hard-failure exit codes only**
- ✅ **Evidence:** Exit 0 for successful reads including partial state (0 of 14 conditions met)
- ✅ **Evidence:** Exit 1 only for: not a git repo, invalid cycle number, repo-root override validation failure
- ✅ **Evidence:** Missing branch/issue/gh CLI handled gracefully with exit 0 + warning messages
- ✅ **Evidence:** Test suite confirms 26 assertions pass including exit code validation

**AC7: Test fixture covers closed and in-flight cycles**
- ✅ **Evidence:** `src/packages/cnos.cdd/commands/cdd-status/test-cn-cdd-status.sh` tests 9 scenarios
- ✅ **Evidence:** Closed cycle simulation (complete artifacts + RELEASE.md)
- ✅ **Evidence:** In-flight cycle simulation (partial artifacts)
- ✅ **Evidence:** Hard failure cases (not-git-repo, missing branch, missing gh)
- ✅ **Evidence:** Legacy branch detection, five-section output, role attribution, help output
- ✅ **Evidence:** All 26 assertions pass

## Self-check

**Did α's work push ambiguity onto β?**
- **No.** Implementation is complete with comprehensive test coverage. All ACs have concrete evidence. Known debt is explicitly declared below.
- **Command behavior:** Deterministic - same inputs produce same outputs. Read-only operations only.
- **Error handling:** Graceful degradation for missing gh CLI, missing branches, non-git repos. No silent failures.
- **Test coverage:** 26 assertions across 9 test scenarios including edge cases and failure modes.

**Is every claim backed by evidence in the diff?**
- **Yes.** Each AC maps to specific lines of code, test outputs, or file paths.
- **AC1:** Command registration evident in cn.package.json line 14-17
- **AC2:** Read-only operations verified by code audit (no write operations found)
- **AC3-5:** Behavior verified by test execution and sample runs
- **AC6:** Exit code behavior proven by test assertions
- **AC7:** Test fixture exists and passes

**Implementation completeness check:**
- **Command:** ✅ Executable shell script following eng/tool standards
- **Registration:** ✅ Package manifest updated for discoverability
- **Tests:** ✅ Comprehensive test suite with golden output and failure cases
- **Help:** ✅ Usage documentation via --help flag
- **Constraints:** ✅ Read-only, deterministic, graceful failure handling

**Role boundary compliance:**
- **α scope:** Implementation and artifact generation complete per alpha/SKILL.md algorithm
- **No β overreach:** Did not make design decisions beyond implementation requirements
- **No γ overreach:** Did not change coordination process or closure gate semantics

## Debt

**AC4 condition count discrepancy:**
- **Issue:** AC4 specifies "10-condition closure list" but gamma/SKILL.md §2.10 defines 14 numbered conditions
- **Resolution:** Implementation follows canonical specification (gamma/SKILL.md) rather than issue description
- **Impact:** Implementation shows "N of 14 conditions" instead of "N of 10 conditions" as written in AC4
- **Next action:** γ should verify whether issue AC4 needs correction or if gamma/SKILL.md needs adjustment

**Process deviation - branch creation:**
- **Issue:** cycle/294 branch does not exist; α cannot create branches per alpha/SKILL.md §2.1
- **Resolution:** Working on main branch with .cdd/unreleased/294/ artifacts
- **Impact:** Self-coherence written to main instead of cycle branch during development
- **Next action:** γ should create cycle/294 branch if needed for β review, or clarify branch management for this cycle

**Legacy branch pattern support:**
- **Issue:** Implementation includes legacy branch detection for claude/* patterns per AC specifications
- **Status:** Working as designed - warns about legacy branches until #287 ships canonical cycle/* naming
- **Impact:** Some cycles may show legacy branch warnings in output
- **Next action:** No action needed - explicitly deferred in issue until #287 completion

**JSON output format:**
- **Issue:** Text-only output in v0; JSON format mentioned as deferred in issue scope
- **Status:** Explicitly deferred per issue scope
- **Impact:** No programmatic consumption API available yet
- **Next action:** Future enhancement when downstream consumer identified
