This file reserves session ID 0033 for ecomm. The driver replaces this body with the full transcript and renames the file to its final SESSION-0033.0-TRANSCRIPT-2026-06-11T21-31--.md form at session end.

Launch prompt

/goal next → resumed stored goal: Plan and build SLICE-6 of SD-0002 (export & the round-trip lock: canonical serializer — one codec two directions, streamed GET /api/products/export + status-filter UI, enable the Export action on the Products page, nothing_to_apply no-op preview behavior already shipped, INV-12 property test diff(catalog, import(export(catalog))) = ∅ over text-field catalogs) per wiggleverse-ecomm-content/specs/SD-0002-products-bulk-csv-import-export.md §7.2, anchored on wiggleverse/wiggleverse-ecomm#13 — DoD: BUC-3/4 acceptance, INV-12 property test green, E2E e2e_export_download + e2e_roundtrip_noop green, TEL-3 emitting, DOC-1 updated, version 0.6.0 shipped through merge + PPE.

Plan

Anchor: design wiggleverse-ecomm-content/specs/SD-0002-products-bulk-csv-import-export.md (§7.2 SLICE-6) — ELIGIBLE per R2a (approved Solution Design); tracker anchor wiggleverse/wiggleverse-ecomm#13 (Feature, parent epic #12). Posture: autonomous (planning-and-executing default).

SLICE-6 — export & the round-trip lock (completes PUC-9, PUC-10):

1. Init done: adopted+finalized dead session 0029; claimed 0033; canonical main fast-forwarded to 011f4d5 (v0.5.0); isolated in worktree worktree-slice-6-export-roundtrip (session 0027 in flight, unbannered).
2. Write JIT implementation plan (superpowers:writing-plans) from SD-0002: canonical serializer (one codec, two directions), streamed GET /api/products/export?status=… (409 empty_catalog), Export menu UI on the Products page (status filter; disabled-with-note when empty), PUC-10 round-trip noop UX, INV-12 property test over text-field catalogs, TEL-3 catalog_exported, E2E e2e_export_download + e2e_roundtrip_noop, DOC-1 update, version 0.6.0.
3. Execute the plan (subagent-driven), gates: check.sh + e2e.sh green.
4. Ship through §9: merge PR → tag v0.6.0 + release tag → flotilla PPE deploy → PPE smoke. Prod promotion stays operator-gated.

Plan written (14 tasks) → docs/superpowers/plans/2026-06-11-slice-6-export-roundtrip.md. Heart: serialize.py (one codec two directions) reusing the CatalogProduct snapshot the diff engine reads; INV-12 locked by a 200-catalog property test + e2e_roundtrip_noop. Executing subagent-driven.

Implementation outcome (pre-ship checkpoint)

SLICE-6 built subagent-driven (13 commits on worktree-slice-6-export-roundtrip, off main @ 011f4d5 / v0.5.0). What landed:

• serialize.py — canonical serializer (one codec, two directions): the CatalogProduct snapshot → canonical CSV, inverse of codec/validate, §6.5.1 row grammar (product fields + option names on row 0, variant-per-row, images interleaved, image-only rows, no Option*Value for no-option products).
• repo.export_catalog (status-filtered, sorted snapshot) + service.export_catalog (streamed, eager EmptyCatalog, TEL-3 catalog_exported) + GET /api/products/export (StreamingResponse, 409 empty_catalog, 422 bad status).
• Frontend export status-filter menu on the Products page (native <details> disclosure; disabled-with-note when empty); exportUrl / EXPORT_STATUSES / isExportEnabled helpers.
• INV-12 locked by a 200-catalog property test + 2 E2E (e2e_export_download, e2e_roundtrip_noop). DOC-1/DOC-4 updated. v0.6.0.
• Final code review caught a real INV-12 bug the green tests missed: Variant Position is a CatalogVariant attribute (not a fields{} entry), so the serializer emitted an empty cell → re-import reset position to file order → non-sequential stored positions round-tripped to a spurious update. Fixed (emit str(variant.position)); property generator strengthened to non-sequential positions + targeted regression test. The bug was reproduced, fixed TDD (red→green), re-verified.

Gates: check.sh green (lint-imports, 166 backend pytest, frontend build, 14 vitest); e2e.sh 6/6 green. Next: push → PR → merge → tag v0.6.0 + release tag → flotilla PPE deploy → PPE smoke.

Deferred decisions

• Task 9 RTL-vs-pure-helper (plan's adaptive point): repo has no @testing-library/react/jsdom and uses pure-logic .test.ts only — took the pure-helper path (exportMenu.ts + .test.ts), JSX verified by E2E. Avoided dragging in a test framework as a slice side effect (matches SLICE-2/3).
• Stale frontend lockfile: package-lock.json was at 0.4.0 (SLICE-5 bumped package.json but not the lock); npm version 0.6.0 synced both. Harmless.

Autonomous-mode low-confidence calls the driver made and would have liked operator input on. Appended as the session runs; surfaced at finalize. Empty if none.
