# T-2208: T-2204 Slice D — hourly cron for fw inception retrofit-recommendations --apply

## Context

T-2204 Slice D — the **preventive backstop** leg of the recommendation-completeness gate. Slices B (T-2205 Write/Edit hook), B' (T-2207 `create-task.sh` CLI parity), and C (T-2206 `emit_review`/`emit_review_batch` consumer block) all gate at the producer surface — but they cannot catch (a) direct YAML writes that bypass tools, (b) post-hoc `fw task update --workflow-type inception` flips, and (c) the period before an operator wires T-2205's hook into `.claude/settings.json`.

`fw inception retrofit-recommendations --apply` (`lib/inception.sh:911 do_inception_retrofit_recommendations`) already exists from T-1716 Stream C and scans `.tasks/active/` for inceptions with empty / template-only `## Recommendation` blocks, injecting a DEFER stub with a self-retrofit attribution comment. It is idempotent — current dry-run reports "No active inceptions need Recommendation retrofit", so the cron is a future-drift defence, not a backlog catch-up.

This slice adds an **hourly cron entry** invoking `fw inception retrofit-recommendations --apply`, regenerates and verifies the crontab (L-364 mandatory check), and closes the producer/consumer parity arc opened by T-1716.

## Acceptance Criteria

### Agent
- [x] Cron registry entry exists: `.context/cron-registry.yaml` contains a job with `id: inception-retrofit-rec-hourly` invoking `fw inception retrofit-recommendations --apply` on an hourly schedule, with `origin_task: T-2208`, `status: active`, and a description.
- [x] `fw cron generate` succeeds and produces a crontab containing the `inception-retrofit-rec-hourly` line (registry → generated transition).
- [x] `fw doctor` reports cron in sync AND does not report "Cron registry edited but not generated" (L-364 mandatory dual-clause check, T-1942/T-1943).
- [x] `fw cron status` (or `list`) lists `inception-retrofit-rec-hourly` as active.
- [x] `fw cron run inception-retrofit-rec-hourly` executes successfully end-to-end (deployed→executable check, the L-365 advisory transition).
- [x] Idempotence: a second `fw inception retrofit-recommendations --apply` invocation after the first reports zero changes and exits 0 (so the cron does not flap on already-clean state).
- [x] Reviewer PASS: `bin/fw reviewer T-2208 2>&1 | grep -q "Overall:.*PASS"`.

## Verification

# L-364 mandatory cron-touching gate (T-1942/T-1943 dual-clause)
out=$(bin/fw doctor 2>&1); echo "$out" | grep -q "Cron registry in sync" && ! echo "$out" | grep -q "Cron registry edited but not generated"

# Registry contains the new entry
grep -q "id: inception-retrofit-rec-hourly" .context/cron-registry.yaml

# Generated crontab carries the command
out=$(bin/fw cron status 2>&1); echo "$out" | grep -q "inception-retrofit-rec-hourly"

# Idempotence on already-clean state
out=$(bin/fw inception retrofit-recommendations --apply 2>&1); echo "$out" | grep -q "No active inceptions need Recommendation retrofit"

# Reviewer static-scan
out=$(bin/fw reviewer T-2208 2>&1); echo "$out" | grep -q "Overall:.*PASS"

## RCA

<!-- REQUIRED for bug-class tasks (workflow_type=build with bug-tag, OR title matches
     fix/bug/rca/broken/crash/error/regression/fail/hotfix).
     Non-bug-class tasks may leave this section empty or remove it.

     For bug-class, fill in:
       **Symptom:** what was observed (the user-facing manifestation).
       **Root cause:** the specific structural/logical gap — not "the code was wrong".
       **Why structurally allowed:** what in the framework/code/tooling let this go undetected.
       **Prevention:** what catches the next instance (test/lint/gate/doc/learning) — distinct from the fix itself.

     The completion gate (T-1550, G-019) blocks --status work-completed when
     bug-class AND this section is empty/template-only. Use --skip-rca to bypass (logged).
-->

## Evolution

<!-- REQUIRED for arc-tagged build tasks (tags include arc:*). Captures how
     understanding evolved during build — what was learned that wasn't known at
     filing, what in the original plan no longer fits, what triggered pivots
     or new sub-tasks. Mandatory at slice boundaries (when applicable) and
     before --status work-completed.

     Origin: T-1717 grill Q4 — "the understanding of what we need and want
     evolves with the process of materialisation." Structural counter to §ACD:
     spec-vs-build divergence is logged as soon as it happens, not lost as
     folklore.

     Format (one entry per slice boundary or significant insight):
       ### YYYY-MM-DD — [topic]
       - **What changed:** [what we learned that we didn't know at filing]
       - **Plan impact:** [what in the plan no longer fits]
       - **Triggered:** [new sub-task / pivot / scope cut, with task ID if filed]

     The completion gate (T-1718) blocks --status work-completed when this
     section exists but is empty/template-only. Use --skip-evolution to bypass
     (logged Tier-2). Non-arc tasks may leave this empty.
-->

## Decisions

<!-- Record decisions ONLY when choosing between alternatives.
     Skip for tasks with no meaningful choices.
     Format:
     ### [date] — [topic]
     - **Chose:** [what was decided]
     - **Why:** [rationale]
     - **Rejected:** [alternatives and why not]
-->

## Decision

<!-- Filled at completion of inception tasks via:
     fw inception decide T-XXX go|no-go|defer --rationale "..."

     For non-inception tasks this section is ignored. Kept in template
     so `fw inception decide` (lib/inception.sh) finds the anchor heading
     without auto-creating; T-1832 added auto-create as fallback for
     legacy tasks lacking this section. -->
