Lesson 235: Q2 Spring Fest Shipping Capstone Receipt (2026)

Direct answer: Q2 2027 spring fest shipping closes when q2_spring_fest_capstone_v1.json links five child receipts from Lessons 230–234, proves build_label alignment across art throttle, audio banks, CJK store copy, landing LCP, and trailer stereo + embed smoke, and points to Q1 capstone (229) plus H2 capstone (223) so May fest traffic is not “shipping GREEN, recovery RED.”

Why this matters now (May 2027 fest traffic gate)

May 2027 producers filed five shipping receipts—Fab 8K throttle, FMOD bank strip, CJK short description, Spline fest landing LCP, micro-trailer stereo—but partners still ask: “Is this build safe for depot size, installed audio, localized store copy, fest hub LCP, and store trailer embed?” Thursday BUILD_RECEIPT review needs one Q2 Capstone section, not five Slack threads.

This lesson closes arc 230–235 (same pattern as Lesson 229 Q1 capstone). Pairs Blender 8K throttle guide, Unity FMOD bank-strip preflight, Photoshop CJK export preflight, Spline fest traffic spike preflight, and Audacity stereo preflight.

Beginner path (60-minute capstone audit)

Time: ~60 minutes when child lessons done; 90 minutes first full Q2 audit.

Developer path (gates P1–P8)

Child receipt crosswalk

P5 child note: Lesson 234 requires store_embed_mute_smoke_receipt_v1 pass: true inside or linked from parent—capstone checks 234 fest_promotion_allowed, not stereo JSON alone.

P1 child note: Lesson 230 may crosswalk Lesson 204—capstone checks 230 pass only.

BUILD_RECEIPT capstone row

ALTER TABLE release_publish_gate ADD COLUMN IF NOT EXISTS
  q2_spring_fest_capstone_blocked BOOLEAN NOT NULL DEFAULT false;

CI verify_q2_spring_fest_capstone_v1 fails when q2_promotion_allowed is false and May fest visibility flag is set.

Key takeaways

1. Capstone = wiring Lessons 230–234—not re-running Blender, Build Report, Weblate, Lighthouse, and ffprobe from scratch.
2. build_label joins art, audio, store copy, web LCP, and trailer rows (P6).
3. Lesson 231 pairs Lesson 219—strings can pass while banks fail.
4. Lesson 234 blocks promotion without embed smoke child—stereo WAV alone is insufficient (P5).
5. Lesson 233 CrUX spot may be N/A inside child receipt—still requires lab LCP pass.
6. Lesson 229 Q1 still required—shipping without January recovery fails partner audit (P7).
7. Lesson 223 H2 still required—fest hardening baseline (P7).
8. Q2 arc 230–235 closed — Course-Planner refill required for next live-ops wave.
9. Thursday review lists 230–234 pass/fail in one Q2 Capstone section.
10. Clip Studio hash preflight is optional sibling for 2D sheets—not in this Q2 five-pack.

Common mistakes

• Filing capstone while 232 CJK save still fails in Steamworks.
• Promoting fest URL while 233 lcp_fest_pass is false.
• micro_trailer_stereo GREEN but embed smoke RED.
• Different build_label on 231 vs 230 depot.
• Skipping 229 because “Q2 is a new arc.”
• Re-running Fab import in capstone instead of reading 230 receipt.

Troubleshooting

Mini exercise (85 minutes)

1. Mismatch one child build_label—confirm P6 fails.
2. Fix crosswalk; verify five paths resolve.
3. Confirm 234 child STORE_EMBED_MUTE_SMOKE_RECEIPT.json linked.
4. Link 229 + 223 capstone JSON paths.
5. File q2_spring_fest_capstone_v1.json.
6. Run Thursday review Q2 Capstone section.

Continuity — Q2 arc close (230–235)

Previous: Lesson 234 — Audacity micro-trailer stereo embed
Prior recovery arc: Lesson 229 — Q1 post-fest capstone
Prior fest arc: Lesson 223 — H2 fest hardening capstone

FAQ

Same as Lesson 229?
229 wires 224–228 January recovery; 235 wires 230–234 May spring fest shipping.

Same as Lesson 223?
223 is October fest hardening; 235 is May store + web + depot shipping receipts.

Can we skip embed smoke?
No—234 requires child store_embed_mute_smoke for P5.

Course-Planner next?
Q2 queue 230–235 is complete — Course-Planner refill required before the next go expects new lessons.

One capstone row for Q2 spring fest shipping—or May promotion is five receipts and zero accountability.
