+📌 **Team update (2026-03-30T00:46:00Z — PRD-120 CI Gating Review Verdict: APPROVED WITH CONDITIONS):** Booster completed CI/CD domain review for PRD-120. Verdict: **APPROVED WITH CONDITIONS**. CI gating approach technically sound and implementable. Cron detection gate feasible; allowlist mechanism practical; GitHub Actions integration straightforward. Key conditions: (1) gate workflow must use path-based filtering to avoid false triggering, (2) YAML parsing must tolerate both commented and active schedules to minimize false positives, (3) allowlist must support regex for flexible workflow matching, (4) test matrix required for edge cases. Recommendation: State machine YAML parsing over regex. Effort: 3–4 weeks (80–120 hours). Phase assessment: Phase 1–2 low-risk; Phase 3 (CI gate) medium complexity but achievable; Phase 4 orthogonal to CI domain.

+### PRD-120 CI Gating Review — June 25, 2026
+
+**Context:** Flight authored PRD-120 (Cron Disable + CI Gating + Feature Versioning) addressing silent GitHub Actions minutes burn on new installs and upgrades. Three interconnected areas: (1) Cron disable on init/upgrade, (2) CI gating to prevent cron bleedthrough, (3) Feature change management system.
+
+**Booster's Primary Review:** CI gating for unauthorized cron schedules (FR-3).
+
+**Key Findings:**
+
+**✅ APPROVED WITH CONDITIONS** — Gate is technically sound and implementable.
+
+**Technical Assessment:**
+1. **Cron Detection — Sound:** Schedule detection via state machine (not naive regex) correctly identifies `schedule:` blocks while avoiding false positives on commented schedules and workflow names containing "schedule."
+2. **Allowlist Mechanism — Practical:** Config-driven allowlist in `squad.config.ts` works, but should support glob patterns (`squad-*.yml`) to reduce toil. Fallback to `.squad/schedule-policy.json` JSON recommended to reduce parsing complexity.
+3. **GitHub Actions Integration — Well-Designed:** Trigger on `pull_request` with `.github/workflows/**` path filter is correct. Zero false triggers, negligible cost (~0.1 min/month for typical repos). Gate is orthogonal to existing CI checks (tests, preflight, publish).
+4. **False Positives/Negatives:** Risk is LOW with recommended mitigations. State machine parsing, 15+ test cases (YAML edge cases), and diagnostic logging prevent most issues. False negative risk (cron sneaking in) mitigated by making gate opt-in for existing repos.
+
+**Concerns & Recommendations:**
+- Gate must **never run on `push: main/dev`** — only `pull_request` to prevent locking out releases if gate logic breaks
+- Gate should **log all execution** to `.squad/log/cron-gate-{timestamp}.log` for debugging
+- Allowlist must support **glob patterns** (`squad-*.yml`, `{hourly,daily}-*.yml`)
+- Error messages must include file path, line number, allowlist guidance, and link to docs
+
+**Effort Estimate:** 1.5–2 weeks for Booster (gate workflow + installation + test support)
+- Gate workflow implementation: ~30–40 hours
+- Installation command (`squad schedule gate init`): ~8–12 hours
+- Test coverage (15+ YAML edge cases + allowlist): ~16–24 hours (with FIDO)
+
+**Test Matrix:** 15 test cases covering:
+- Simple schedule blocks, spacing variations, multiline YAML
+- Commented schedules (migration markers), schedule in comments/names
+- Allowlist matching (exact paths, glob patterns)
+- YAML edge cases (anchors, aliases, template expressions)
+- Error message content, gate performance (<5 seconds for 15 workflows)
+
+**Critical Path:** Phase 1 (templates) → Phase 2 (upgrade) → Phase 3 (gate, parallel with Phase 4 feature flags).
+
+**Approval Gate:** ✅ Ready for Flight approval + implementation kickoff

+📌 **Team update (2026-03-30T00:46:00Z — PRD-120 Runtime Feasibility Review Verdict: APPROVE WITH CHANGES):** EECOM completed runtime feasibility assessment for PRD-120 Cron Disable + CI Gating + Feature Management. Verdict: **APPROVE WITH CHANGES**. Key finding: Squad's existing infrastructure provides 70% foundation already. No CopilotClient/Adapter Layer changes required (config-layer only). Feature flag system straightforward; schedule command is main greenfield effort (~18h scope). Recommendation: Defer CI gate (FR-3) to v0.10.1 to keep v0.10.0 scope tight; schedule command and feature flags can ship v0.10.0 without blocking.

+### PRD-120 Runtime Feasibility Review (2026-07-25)
+
+**Context:** Flight submitted PRD-120 (Cron Disable, CI Gating, Feature Management) for team review. EECOM tasked with assessing runtime implementation feasibility for Functional Requirements 1–4 and identifying core runtime changes needed.
+
+**Key Findings:**
+
+1. **Foundation already exists** — 70% of infrastructure present:
+   - Ceremonies schema already has schedule support (`schedule?: string`, `enabled?: boolean`)
+   - Upgrade machinery (`upgrade.ts`, 362 lines, migration system at line 426) provides solid foundation
+   - Init workflow copying pattern (lines 913–932) reusable for schedule.json template setup
+   - Config loader infrastructure ready for feature flags
+
+2. **Configuration schema extensions are minimal** — Only 2 new optional fields needed in `SquadConfig`:
+   - `features?: Record<string, boolean>` — Feature flag overrides (e.g., `cronSchedules: true`)
+   - `schedulePolicy?: { allowWorkflowCron?: string[] }` — Workflow schedule allowlist
+   - Both fields backward compatible; schema at `packages/squad-sdk/src/config/schema.ts`
+
+3. **Runtime impact is isolated** — CopilotClient and session pool unaffected:
+   - Cron disable affects state (schedule.json) and templates (workflow YAML), not casting/spawn logic
+   - No session lifecycle changes; no adapter layer modifications needed
+   - Feature flags are config-only, no runtime data structure changes
+
+4. **Schedule command is greenfield** — Largest implementation effort (~3.5 hours):
+   - No existing `packages/squad-cli/src/cli/commands/schedule.ts`
+   - Needs: enable <id>, enable --all, disable <id>, list subcommands
+   - Straightforward JSON I/O; can follow existing CLI command patterns (e.g., plugin.ts, doctor.ts)
+
+5. **Workflow detection strategy** — Regex-based approach chosen over YAML parser (maintains NFR-3: zero new dependencies):
+   - Pattern: `/^(\s*)schedule:\s*$/gm` for block detection
+   - Risk: Regex may miss edge cases (quoted cron values, multiline syntax)
+   - Mitigation: Comprehensive test matrix; parser as fallback in v0.10.1 if needed
+
+6. **Idempotency is critical** — Upgrade path must handle multiple runs safely:
+   - `.squad/schedule.json.pre-upgrade` backup file signals first-run completion
+   - Regex-based workflow commenting must detect already-commented blocks
+   - Risk: Without careful implementation, second upgrade could corrupt workflow files or duplicate backup files
+
+**Verdict:** **APPROVE WITH CHANGES**
+- FR-1 (Cron Disable Init/Upgrade) — Fully feasible, recommend v0.10.0
+- FR-4.3 (Feature Flags) — Fully feasible, recommend v0.10.0
+- FR-3 (CI Gate) — Defer to v0.10.1 (doesn't block cron disable, adds ~6 hours complexity)
+- FR-4.1–4.5 (Change Manifest System) — Defer to v0.10.1 (infrastructure-heavy, not on critical path)
+
+**Complexity estimate:**
+- v0.10.0 core (FR-1 + FR-4.3 + schedule command): ~18 hours
+- Full scope (include FR-3 + FR-4.x): ~28 hours
+- Rationale: Deferring gate + manifest keeps v0.10.0 tight; users get immediate value from cron disable
+
+**Key recommendations for implementation:**
+1. Config schema: Add both fields as optional, with defensive defaults in config loader
+2. Init: Reuse workflow copy pattern for schedule.json template (static JSON at init time)
+3. Upgrade: Extend `TEMPLATE_MANIFEST` pattern for schedule.json; create migration functions `migrateSchedules()` and `migrateWorkflows()` with idempotency guards
+4. Schedule command: Follow existing CLI patterns (dynamic imports, help text wiring in cli-entry.ts)
+5. Feature flags: Implement as simple config-level boolean overrides; warn on unknown flags for forward compatibility
+6. Tests: New test suite ~450 lines; extend existing init/upgrade tests for schedule migration; add idempotency matrix tests for workflow commenting
+
+**Risk mitigations:**
+- Idempotency: Backup file flag + regex-based detection for already-commented blocks; regression test (upgrade twice, compare files)
+- Regex fragility: Test matrix covering inline/multiline/quoted/commented edge cases; parser fallback approved as v0.10.1 tech debt
+- User experience: `squad schedule enable` cost warning every time; `squad doctor` checks enabled schedules
+- Feature flag sprawl: Policy (flags sunset after 2 major versions) owned by Procedures; unknown flags warn not error
+
+**Questions for Flight/team:** See review document section "Open Questions" for v0.10.0 vs v0.10.1 delineation, multi-repo support, changelog automation strategy.
