Friday March Capstone Closeout BUILD_RECEIPT Row Review - Ten Minutes Before April Content Update Upload - 2026

Friday 4:30 p.m., March 27: #post-fest-sprint celebrates "March done." Monday's calendar already lists April Addressables bundle upload and summer content branch promote. BUILD_RECEIPT.json shows march_post_fest_sprint_weekly_ok: true from W11 while jq March weekly log stops at W12 with no W13 line. MERGE-002 merged Thursday but merge_exception_count still says 1. Engineering runway W13 cap row is blank while contractor invoice cites MERGE-003 that does not exist on disk.

March 2027 post-fest sprint ends with receipt sprawl—Monday debrief annex, wishlist velocity baselines, evidence sprint E7, weekly jq diffs, engineering cash caps, MERGE integers, and October RC label cousins each filed in separate paths. Teams that skip Friday March capstone jump to April Addressables uploads and lose the one BUILD_RECEIPT story summer branches need—not because engineers forgot to ship, but because nobody ran C1–C10 on the root receipt before content-update promotion.

Sunday February closeout latched post_fest_debrief_allowed after live week. Monday January reconciliation latched february_upload_allowed before first SteamPipe. Friday November capstone latched december_freeze_allowed before holiday. This Process & Workflow article defines a ten-minute Friday March capstone row review: diff March sprint root columns, consume march_post_fest_sprint_weekly_log.jsonl annex, file march_capstone_closeout_receipt_v1.json, set april_content_update_allowed: true only when C4–C8 pass—the last human gate before April Addressables upload and summer branch promotion.

Non-repetition note: Sunday February owns live-week C1–C10 closeout + jsonl annex after D1–D7. Monday January owns M1–M10 cross-era reconciliation. jq March weekly owns J1–J6 per-ISO-week diff. MERGE opinion owns M1–M6 trunk merge integers. This URL owns Friday March C1–C10 capstone diff + weekly jsonl annex latch after W10–W13 post-fest sprint ends.

Pair Monday post-fest debrief facilitator, 7-day evidence sprint, October RC label evening, cluster #1–#11, post-fest Whisper handoff (#12 published—closes March cluster), and BUILD_RECEIPT beginner pipeline.

Why this matters now (March 2027 ends Friday)

1. April Addressables uploads — Unity/Godot/Unreal content pipelines burn wall-clock when BUILD_RECEIPT still points at February fest depot assumptions.
2. Weekly jsonl annex debt — March sprint weekly produced four ISO weeks of diffs—capstone must index them on BUILD_RECEIPT, not leave W13 missing.
3. MERGE count drift — MERGE list exceptions[].length must match root merge_exception_count before summer branch screenshots.
4. Engineering runway close — March cash worksheet W13 row must reconcile contractor invoices with MERGE ids.
5. Whisper handoff — Post-fest handoff #12 (published) consumes clips_index[] from February same-day triage—not January batch schema.

Direct answer: On Friday March 27, 2027 (default last business day of post-fest sprint), run C1–C10 on BUILD_RECEIPT March columns; write march_capstone_closeout_receipt_v1.json with weekly_jsonl_annex[] pointers; set april_content_update_allowed: true only when C4–C8 GREEN—block April Addressables upload when capstone diff is RED even if W12 jq weekly was GREEN.

Who this ritual is for

Time: 10 minutes every Friday of March capstone week (default 2027-03-27 before April upload); 5 minutes optional mid-March checkpoint on W11.
Prerequisites: Cluster #1–#10 March receipts filed, evidence sprint E7 GREEN, full march_post_fest_sprint_weekly_log.jsonl through W13 (or documented waiver).

Ritual map — post-fest sprint through Friday latch

W12 jq GREEN with Friday capstone RED still ships content-update theater—Addressables promote a depot BUILD_RECEIPT cannot explain across February→March.

Add rows when Guide #48 ships—never delete March keys without receipt_version bump in capstone notes.

Gates C1–C10 (April upload blockers)

C4–C8 are April upload blockers when RED. C9 YELLOW allows upload only with written waiver—summer branch promote without RC label receipt.

Producer rule: No April Addressables calendar invite until capstone receipt path is in partner zip.

Beginner mistake: Treating W12 jq GREEN as "March done" without filing W13 capstone line—April upload inherits incomplete annex.

Capstone vs weekly jq vs Sunday February closeout

Rule: Weekly jq feeds capstone annex—it does not replace Friday C1–C10.

jq one-liners (Friday diff pack)

# Weekly jsonl line count — expect 4 for W10–W13
jq -s 'length' release-evidence/post-fest/march_post_fest_sprint_weekly_log.jsonl

# Last weekly receipt iso_week
jq -r '.weekly_jsonl_annex[-1].iso_week' release-evidence/post-fest/MARCH_CAPSTONE_CLOSEOUT_RECEIPT.json

# MERGE tail id vs BUILD_RECEIPT count
echo "merge_count=$(jq -r '.merge_exception_count' BUILD_RECEIPT.json)"
jq -r '.exceptions[-1].id' release-evidence/post-fest/MERGE_EXCEPTION_LIST_RECEIPT.json

# Engineering runway W13 cap vs actual
jq '.weeks[] | select(.iso_week=="2027-W13")' release-evidence/ops/march_engineering_runway_receipt_v1.json

Attach jq output to capstone notes when C9 is YELLOW.

Key takeaways

1. March 2027 ends Friday with C1–C10 capstone—not "jq was GREEN last week."
2. march_capstone_closeout_receipt_v1.json indexes W10–W13 weekly jsonl annex.
3. april_content_update_allowed latches only when C4–C8 GREEN.
4. Sunday February pointer is C2 prerequisite—not optional folklore.
5. MERGE opinion C4 requires count + label parity.
6. Engineering runway C6 closes W13 contractor cap.
7. jq March weekly feeds capstone—it does not replace it.
8. Post-fest Whisper handoff (#12 published) consumes forward_whisper_handoff path on capstone receipt.
9. verify_march_capstone_closeout.sh gives CI one exit code before Addressables.
10. Partner zip includes weekly log + MERGE list + runway receipt.
11. C9 YELLOW allows upload only with October RC waiver documented.
12. Prevention beats April content update on February fest depot ghosts.
13. Ten-minute Friday card is enough for solo founders—same bar as November Friday cousin.

FAQ

Is this the same as Sunday February closeout?

No—Sunday owns live-week D7 annex; Friday March owns post-fest W10–W13 weekly annex before April upload.

Can we skip W13 if W12 was GREEN?

No—C7 expects four ISO weeks or documented producer waiver in notes.

How does Monday January reconciliation relate?

Cousin capstone latch pattern—January february_upload_allowed, March april_content_update_allowed.

What if empty annex recovery was filed?

C8 waiver with recovery receipt path—capstone still runs; do not skip C1–C10.

When does Whisper handoff start?

After C10 GREEN—capstone sets forward_whisper_handoff pointer to post-fest handoff receipt (#12 published).

Does this block October RC label evening?

No—C9 documents RC path when summer branch promote is planned same month.

RED / YELLOW / GREEN routing (C gates)

Closing

March post-fest sprint without Friday capstone becomes April upload folklore—weekly jq lines, MERGE integers, and engineering caps drift from February closeout truth while summer branches promote. File march_capstone_closeout_receipt_v1.json, consume march_post_fest_sprint_weekly_log.jsonl W10–W13, and run verify_march_capstone_closeout.sh before Addressables spend wall-clock. Beginners use the ten-minute card; producers block April calendar invites until C4–C8 GREEN; working devs wire Friday CI. Post-fest Whisper handoff drains clips_index[] after capstone latch—closing March cluster #1–#12.
