# α Close-out — Cycle #344-B

[provisional — pending β outcome]

## Summary

Cycle B delivered the reference notifier implementation scope for `cdd/activation/`:
a Telegram notification adapter (`notify.sh` + `cdd-notify.yml`), two GitHub Actions
workflow templates (`cdd-artifact-validate.yml`, `cdd-cycle-on-merge.yml`), and
two README files documenting setup and usage.

All 5 ACs met. No existing surfaces modified. Work is purely additive.

## Implementation observations

- The 4-event `case` dispatch in `notify.sh` directly mirrors the `activation/SKILL.md §10.1`
  event table — no interpretation required. The adapter contract (§10.2) maps cleanly to a
  ~130-line shell script.
- The `cdd-artifact-validate.yml` "validate-release-gate.sh not found" error path required an
  explicit existence check step before the actual script call — this is the pattern that satisfies
  B.AC2 precisely (the script call alone would produce an ambiguous "file not found" error from
  bash, not a named diagnostic from the workflow).
- The `cdd-notify.yml` trigger heuristics (detecting beta-verdict from file list in push payload)
  are approximate; this is a known-debt item declared in §Debt.

## Friction

None. The scope was well-specified and the existing `activation/SKILL.md §10.1–§10.2`
provided a complete contract to implement against.

## Patterns

- Template-distribution model (copy-pasteable reference implementations) is appropriate
  for CDD activation tooling. Tenants need starting points, not vendored dependencies.
- Shell + GitHub Actions is the right stack for CI notification adapters at this scale.
