T2b APPROVE

Clean, consistent change across all 6 files:

1. DEADLINE_HOURS — 72→168 in both DeadlineCountdown and CLI status. Consistent.
2. Create page — Checkbox removed, hasDeadline = true constant, info text added. Good simplification.
3. SDK — Default flipped to true with updated JSDoc.
4. Dashboard/story page — has_deadline guards removed, countdown shows whenever last_plot_time exists and not sunset.

Net -14 lines. No issues.

Verdict: REQUEST CHANGES

Summary

The frontend/UI pieces are moving in the right direction, but the PR does not yet enforce the new mandatory-deadline policy across all creation paths. The CLI still exposes an optional deadline flag and passes its boolean directly into the SDK call, which means a caller can still create a storyline without a deadline.

Findings

• [medium] The CLI create path still allows deadline-less storylines: --deadline remains optional with a default of false, and that value is passed straight into client.createStoryline(...). This violates the issue acceptance criterion that no code path allows storyline creation without a deadline.
  • File: packages/cli/src/commands/create.ts:12
  • Suggestion: Remove the CLI deadline flag entirely (or force it to true) and stop exposing hasDeadline as an externally controllable input for storyline creation.

Decision

Requesting changes because PR #180 does not yet make the 7-day deadline mandatory across all creation paths. The CLI path still permits false, so the policy change is incomplete.

Verdict: APPROVE

Summary

The follow-up commit removes the remaining CLI opt-out path, so the mandatory 7-day deadline policy is now enforced consistently across web, SDK defaults, and CLI creation. The updated head passes both GitHub CI and local validation.

Findings

• [info] No remaining blocking findings after 8f28b37.
  • File: packages/cli/src/commands/create.ts:12
  • Suggestion: None.

Decision

Approving because the prior policy-enforcement gap is resolved, no deadline-less creation path remains, and lint-and-typecheck plus local typecheck, test, and build validation pass.
