# Self-Coherence — Cycle #344-B

## §Gap

**Issue:** #344 (meta-issue) — Cycle B scope: Reference notifier implementation

**Version/mode:** CDD 3.15.0 / substantial change (multi-AC, new template artifacts)

**Gap being closed:** `cdd/activation/SKILL.md §10` defines a transport-agnostic notification
interface (event vocabulary + adapter contract) but no reference implementation exists.
Tenants activating CDD have no copy-pasteable starting point for wiring notifications.

Cycle B closes the gap by delivering:
1. `activation/templates/telegram-notifier/` — reference notify.sh + cdd-notify.yml + README
2. `activation/templates/github-actions/` — cdd-artifact-validate.yml + cdd-cycle-on-merge.yml
3. `activation/templates/README.md` — top-level overview of all templates

---

## §Skills

**Tier 1 — CDD lifecycle:**
- `CDD.md` 3.15.0 — canonical lifecycle, §10 event vocabulary, §10.2 adapter contract
- `alpha/SKILL.md` — α role contract (this session)
- `activation/SKILL.md` — notification interface spec (§10, §10.1, §10.2, §11)

**Tier 2 — Engineering:**
- Shell authoring conventions (bash -n lint, shellcheck where available)
- YAML syntax (python3 yaml.safe_load validation before commit)
- Markdown authoring (word-count for README constraints)

**Tier 3 — Issue-specific:**
- No additional Tier 3 skills loaded; the work is template/docs authoring with
  no Go/TypeScript/specialized-runtime surface.

**Design:** Not required — this is a new template tree with no inter-package
contract dependencies. The scope is purely additive (new directory under
`activation/templates/`); no existing surfaces are modified.

**Plan:** Not required — artifact order is prescribed by the issue ACs (B.AC1–B.AC5);
no non-trivial sequencing beyond that order.

---

## §ACs

### B.AC1 — Telegram notifier reference impl works end-to-end

**Evidence:**
- `activation/templates/telegram-notifier/notify.sh` — single-file shell script, uses
  `curl` to call `https://api.telegram.org/bot${CDD_TELEGRAM_BOT_TOKEN}/sendMessage`
- Uses `$CDD_TELEGRAM_BOT_TOKEN` and `$CDD_TELEGRAM_CHAT_ID` from environment (set via
  GitHub secrets in the workflow); no hardcoded values anywhere in the script
- All 4 events handled: `cycle-open` (L42), `beta-verdict` (L50), `cycle-rc` (L57),
  `cycle-merge` (L63) in the `case "$EVENT" in` dispatch block
- `cdd-notify.yml` wires the workflow: jobs `notify-cycle-open`, `notify-beta-verdict`,
  `notify-cycle-rc`, `notify-cycle-merge` each set `CDD_EVENT` and call `notify.sh`
- Secrets-absent path: lines L32–39 check for empty TOKEN/CHAT_ID, log a warning, exit 0

**Status: MET**

### B.AC2 — Artifact validator catches missing files

**Evidence:**
- `activation/templates/github-actions/cdd-artifact-validate.yml`
- Triggers `on: push: branches: ['cycle/**', 'main']` — both required targets present
- Step "Check validate-release-gate.sh exists" (lines ~26–35) fails with:
  `"ERROR: validate-release-gate.sh not found at scripts/validate-release-gate.sh"`
  and `exit 1` if the script is absent
- Step "Validate CDD artifact presence" calls `bash scripts/validate-release-gate.sh`
  which already produces named-missing-artifact output (verified from the existing script)
- YAML validated via `python3 -c "import yaml; yaml.safe_load(...)"` → YAML OK

**Status: MET**

### B.AC3 — Workflow templates are copy-pasteable

**Evidence:**
- All 3 YAML files (cdd-notify.yml, cdd-artifact-validate.yml, cdd-cycle-on-merge.yml)
  use `${{ secrets.CDD_TELEGRAM_BOT_TOKEN }}` and `${{ secrets.CDD_TELEGRAM_CHAT_ID }}` —
  canonical `CDD_` namespace with no tenant-specific hardcoding
- Each file has inline comments marking what to customize (e.g., `# Customize:` blocks)
- No tenant names, repo names, or hardcoded paths that would need changing beyond
  optional secret name overrides

**Status: MET**

### B.AC4 — README walkthrough

**Evidence:**
- `activation/templates/telegram-notifier/README.md` — 266 words (≤300 limit)
- Steps covered: Step 1 (BotFather bot creation), Step 2 (chat ID retrieval via
  getUpdates), Step 3 (set secrets: CDD_TELEGRAM_BOT_TOKEN + CDD_TELEGRAM_CHAT_ID
  in GitHub Settings), Step 4 (wire workflow files), Step 5 (verify)
- No tokens in the README — only the secret names and API URL pattern

**Status: MET**

### B.AC5 — Notifier honors transport-agnostic event vocabulary

**Evidence:**
- `notify.sh` `case "$EVENT" in` block handles exactly:
  - `cycle-open` — matches `activation/SKILL.md §10.1` row 1
  - `beta-verdict` — matches §10.1 row 2
  - `cycle-rc` — matches §10.1 row 3
  - `cycle-merge` — matches §10.1 row 4
- Unknown event path (line ~72-76): prints warning to stderr and exits 0 with a
  warning log line to stdout — does not fail
- Empty `CDD_EVENT` also exits 0 with warning

**Status: MET**

---

## §Self-check

**Did α's work push ambiguity onto β?**

No. All 5 ACs have concrete evidence mapped to specific file paths and line numbers in
the diff. The artifacts are purely additive (new directory under `activation/templates/`);
no existing surfaces were modified.

**Is every claim backed by evidence in the diff?**

- B.AC1: `notify.sh` exists and passes `bash -n`. The 4-event `case` block is present.
  `cdd-notify.yml` wires all 4 events. Secrets-absent guard is present.
- B.AC2: `cdd-artifact-validate.yml` has the explicit "not found" error and `exit 1`.
  Triggers are `cycle/**` and `main`.
- B.AC3: All YAML uses `${{ secrets.CDD_... }}`. All `# Customize:` blocks mark the
  only tenant-variable locations.
- B.AC4: `wc -w README.md → 266` (verified before commit).
- B.AC5: `case "$EVENT" in` matches all 4 canonical event names from `activation/SKILL.md §10.1`.
  Unknown-event path exits 0 with warning.

**Peer enumeration:**

The work is a new template directory tree. No existing skill files were modified.
The only peer concern is the event vocabulary match against `activation/SKILL.md §10.1`:
grep confirms the 4 event names in `notify.sh` match exactly.

**Harness audit:** Not applicable — no schema-bearing contracts changed.

**Polyglot re-audit:**
- Shell (`notify.sh`): `bash -n` → SYNTAX OK; no dead captures; all `case` branches used
- YAML (`cdd-notify.yml`, `cdd-artifact-validate.yml`, `cdd-cycle-on-merge.yml`):
  `python3 yaml.safe_load` → OK on all three
- Markdown (`README.md` × 2): word counts checked (266, 171); no broken cross-references;
  no tokens

**Known-debt push:** None pushed onto β.

---

## §Debt

1. **cdd-notify.yml heuristics are approximate.** The `beta-verdict` and `cycle-rc` job
   triggers use `contains(join(...))` to detect modified files — this is a best-effort
   heuristic; GitHub Actions does not expose per-commit file diff in a structured list
   for all push cases. In practice, tenants may need to adjust this if their workflow
   structure differs. This is acceptable for a reference implementation (B.AC3 targets
   copy-paste starting point, not production-hardened CI).

2. **notify.sh uses python3 for JSON encoding.** The script uses
   `python3 -c 'import json,sys; print(json.dumps(sys.stdin.read()))'` to escape the
   message for JSON. This requires python3 on the runner (available by default on
   ubuntu-latest). If a tenant needs a pure-bash implementation, they would need to
   replace this with a different escaping approach.

3. **No automated test of notify.sh against a live Telegram endpoint.** Testing
   requires real secrets; the templates are reference implementations meant to be
   validated by the tenant when they configure their secrets (Step 5 in README.md).
   This is inherent to the template-distribution model.

4. **alpha-closeout.md provisional** — written at review-readiness per `alpha/SKILL.md §2.8`
   bounded-dispatch fallback; marked `[provisional — pending β outcome]`.

## §CDD-Trace

**Step 1 — Receive dispatch:** Cycle B dispatch received. Branch `cycle/344-b` checked out.
Git identity set to `alpha@cdd.cnos`.

**Step 2 — Identify gap:** `cdd/activation/SKILL.md §10.2` defines adapter contract with no
reference implementation. Cycle B closes this with a complete template tree.

**Step 3 — Active skills declared:** Tier 1: CDD.md, alpha/SKILL.md, activation/SKILL.md.
Tier 2: shell, YAML, Markdown. Tier 3: none. (See §Skills above.)

**Step 4 — Design:** Not required (purely additive new directory; no inter-package contracts).

**Step 5 — Plan:** Not required (artifact order prescribed by ACs B.AC1–B.AC5).

**Step 6 — Implementation (commit 22be2525):**

Files delivered:
- `src/packages/cnos.cdd/skills/cdd/activation/templates/telegram-notifier/notify.sh`
  — shell adapter; caller: `cdd-notify.yml` (each job step calls `bash .github/cdd/notify.sh`)
- `src/packages/cnos.cdd/skills/cdd/activation/templates/telegram-notifier/cdd-notify.yml`
  — GitHub Actions workflow; caller: GitHub Actions runner on push events
- `src/packages/cnos.cdd/skills/cdd/activation/templates/telegram-notifier/README.md`
  — documentation; caller: tenant reading setup instructions
- `src/packages/cnos.cdd/skills/cdd/activation/templates/github-actions/cdd-artifact-validate.yml`
  — CI workflow; caller: GitHub Actions runner on push events
- `src/packages/cnos.cdd/skills/cdd/activation/templates/github-actions/cdd-cycle-on-merge.yml`
  — CI workflow; caller: GitHub Actions runner on push to main
- `src/packages/cnos.cdd/skills/cdd/activation/templates/README.md`
  — top-level overview; caller: tenant discovering templates

Caller-path trace: all template files are consumed by tenant repos (copy-paste deployment).
Within the cnos repo they are documentation/reference artifacts — no in-repo call site is
expected or required. `cdd-notify.yml` and `cdd-cycle-on-merge.yml` both call `notify.sh`.

**Step 7 — Self-coherence:** This file. Written incrementally (one section per commit) per
`alpha/SKILL.md §2.5`. Sections: §Gap (53aeb6d1), §Skills (3b729d1b), §ACs (450a2754),
§Self-check (82631388), §Debt (1a007688), §CDD-Trace (this commit).

**CDD Trace complete through step 7.**

## Fix Round 1 — addressing β findings (round 2 prep)

**β verdict SHA:** e7d995a4 (β review commit)
**Fix round base SHA:** e7d995a4

### F1 (C — contract/honest-claim) — commit f3b1c72d

**Finding:** B.AC4 names `activation/templates/README.md` as the file containing the
bot-registration → secret-setup → first-activation walkthrough (≤300 words). The original
README was 171 words with no walkthrough prose — only a directory overview.

**Fix applied:** Added a "Quick Start — Telegram Notifier" section to
`activation/templates/README.md` covering all four AC-required steps:
(1) create bot via BotFather, (2) get chat ID via getUpdates, (3) set
`CDD_TELEGRAM_BOT_TOKEN` and `CDD_TELEGRAM_CHAT_ID` secrets, (4) copy files
and wire workflow. Total README word count: 297 (≤300 limit). The
`telegram-notifier/README.md` remains as the detailed reference walkthrough.

**β re-verify:** `wc -w activation/templates/README.md` → 297 words. Walkthrough
covers all B.AC4 required steps at the named file path.

### F2 (B — mechanical/judgment) — commit 79ec55e2

**Finding:** `notify-beta-verdict` job `if:` expression evaluated as
`(A && B && C) || D` due to `&&`/`||` precedence, allowing the
`contains(...modified...)` clause to fire on any branch including `main`.

**Fix applied:** Added parentheses around the two `contains()` clauses:
```
startsWith(github.ref, 'refs/heads/cycle/') &&
github.event.created != true &&
(contains(join(github.event.commits.*.added, ','), 'beta-review.md') ||
 contains(join(github.event.commits.*.modified, ','), 'beta-review.md'))
```
Expression now correctly evaluates as `A && B && (C || D)`.

**Mechanical gates re-run after fix:**
- `bash -n notify.sh` → SYNTAX OK
- `python3 yaml.safe_load(cdd-notify.yml)` → YAML OK

**β re-verify:** Inspect `cdd-notify.yml` lines 60–65; confirm parentheses present
and `contains(...modified...)` clause is inside the outer parentheses.

### F3 (A — judgment) — commit f3b1c72d (same commit as F1)

**Finding:** `activation/templates/README.md` did not mention that
`cdd-artifact-validate.yml` requires `scripts/validate-release-gate.sh` to exist
in the tenant repository.

**Fix applied:** Updated the `cdd-artifact-validate.yml` table row in
`activation/templates/README.md` to include the dependency:
> "requires `scripts/validate-release-gate.sh` in the tenant repository"

**β re-verify:** `grep validate-release-gate activation/templates/README.md`
→ dependency sentence present in the `cdd-artifact-validate.yml` table row.
