Session 0033.0 — Transcript

App: ecomm Start: 2026-06-11T21-31 (PST) · End: 2026-06-11T22-28 (PST) Type: planning-and-executing Claude-Session: 8c956100-2db1-417c-9752-8b5f37348878 Date: 2026-06-11 Goal: Plan and build SLICE-6 of SD-0002 (export & the round-trip lock), anchored on wiggleverse/wiggleverse-ecomm#13. Outcome: SHIPPED — ecomm v0.6.0 LIVE on PPE. PR #29 merged @ 385df8d; flotilla deploy 9/9 green (deploys.id=43); PPE /healthz reports 0.6.0. SLICE-6 done (merge + PPE-green); prod promotion stays the operator's gate.

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): canonical serializer (one codec, two directions) → streamed GET /api/products/export → Export status-filter UI → INV-12 property test → TEL-3 → E2E (e2e_export_download, e2e_roundtrip_noop) → DOC-1 → v0.6.0 → ship through §9.

JIT implementation plan written (14 tasks) at docs/superpowers/plans/2026-06-11-slice-6-export-roundtrip.md (archived at finalize to wiggleverse-ecomm-content/plans/), executed subagent-driven.

Pre-session state

main @ 011f4d5 (v0.5.0, SLICE-5 import spine, shipped session 0032). Two --INPROGRESS sessions surfaced at the dry-run peek: 0027 (live, planning — signin cooldown fix; left in flight) and 0029 (capture, ENDED-UNFINALIZED). Adopted + finalized the dead 0029 placeholder (empty, no work attributable) at init. Because 0027 was a live concurrent same-app session, this session isolated in its own worktree (worktree-slice-6-export-roundtrip).

Turn-by-turn arc

1. Init — /goal next resolved the stored Next /goal: (SLICE-6) from memory; classified planning-and-executing → wgl-planning-and-executing. Computed start; peeked (0027 live, 0029 dead); adopted+finalized 0029; claimed 0033. Fast-forwarded main to 011f4d5; R2a eligibility gate passed on SD-0002. Isolated in a native worktree (EnterWorktree); venv + npm + Postgres up.
2. Plan — surveyed the SLICE-5 code surface (codec/validate/diff/models/ repo/service/main, frontend ProductsPage/productsApi/ImportPreview, e2e harness) so the plan carried exact paths + real signatures. Wrote the 14-task plan, checkpointed the transcript.
3. Execute (subagent-driven, two-stage review per group):
   • Group 1 (Tasks 1–3,6) — serialize.py skeleton → row grammar → INV-12 property test (200 catalogs, passed first try) → decimal coverage. Verified directly (6 tests, linter green).
   • Group 2 (Tasks 4–5) — repo.export_catalog + streamed service.export_catalog + EmptyCatalog + TEL-3. 159 backend tests green; confirmed the eager EmptyCatalog raise.
   • Group 3 (Task 7) — GET /api/products/export (StreamingResponse, 409, 422). 164 backend green.
   • Group 4 (Tasks 8–9) — resolved the plan's RTL-vs-pure-helper fork up front (no RTL in repo → pure-helper path); export menu + helpers. 14 vitest green, build clean; CSS aligned to the real design tokens.
   • Group 5 (Task 11, E2E) — e2e_export_download + e2e_roundtrip_noop; the subagent fixed a real menu-toggle bug in the helper (native <details> stays open after a download → deterministic open). 6/6 E2E green; no serializer bug surfaced through the UI.
   • Tasks 12–13 (controller) — DOC-1/DOC-4 docs + v0.6.0 (VERSION + package.json + lockfile synced via npm version).
4. Final code review (whole diff) — caught a real INV-12 bug the green tests missed: Variant Position is a CatalogVariant attribute, not a fields{} entry, so the serializer's field-loop emitted an empty cell → re-import reset position to file order → non-sequential stored positions round-tripped to a spurious update. Reproduced it, fixed TDD (red→green: emit str(variant.position)), strengthened the property generator to non-sequential positions + a targeted regression. Addressed the reviewer's dead-code note (wired isExportEnabled into the component).
5. Ship — both gates green (check.sh, e2e.sh 6/6); checkpointed; pushed; PR #29 opened + merged; tagged v0.6.0 + release/2026-06-11T22-23; flotilla PPE deploy 9/9 green; PPE smoke (healthz 0.6.0, export 401 gated, sample.csv 200).

Cut state (end of session)

Repo	Ref	What
wiggleverse-ecomm	main @ 385df8d	PR #29 merged (13 SLICE-6 commits 627e257…af72299)
wiggleverse-ecomm	tags	v0.6.0, release/2026-06-11T22-23 on 385df8d
wiggleverse-ecomm-content	main @ 781b4d8	plan archived to plans/2026-06-11-slice-6-export-roundtrip.md
PPE (ecomm-ppe VM)	deploys.id=43	v0.6.0 live; /healthz ok 0.6.0

All gates green: check.sh (lint-imports, backend pytest, frontend build, 14 vitest); e2e.sh 6/6. Worktree torn down at finalize (branch merged).

What lands on the operator's plate

• SLICE-6 is done, not shipped to prod. Prod promotion is the operator's gate (§9.1): promote the validated v0.6.0 / release/2026-06-11T22-23 tag at your cadence. ecomm has no prod env yet (SLICE-4 prod stand-up still queued, closes Feature #1).
• Patchwatch warning on the deploy: ecomm has no GITEA_BOT_TOKEN bound (known ecomm#19, P3) — patchwatch labels not provisioned. Non-blocking.
• SLICE-7 (images) needs a flotilla provision-bucket operator gesture for the per-env private GCS bucket at its PPE deploy — that session will hand it to you.

Deferred decisions

• Task 9 testing approach — repo has no @testing-library/react/jsdom and uses pure-logic .test.ts only. Took the pure-helper path (exportMenu.ts + pure tests; JSX verified by E2E) rather than introducing a test framework as a slice side effect. Matches SLICE-2/3 convention. Alternative was adding RTL.
• 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; folded into the version-bump commit.

Prompt the operator can paste into the next session

/goal Plan and build SLICE-7 of SD-0002 (images pipeline end-to-end: platform/objectstore port with local + GCS adapters, the post-commit in-process image-fetch task with restart-recovery, WebP renditions at fetch + reject-low-res, the app-served authorized image route with immutable caching, run-detail images section, INV-12 extended over images / hosted-URL recognition) per wiggleverse-ecomm-content/specs/SD-0002-products-bulk-csv-import-export.md §7.2 SLICE-7, anchored on wiggleverse/wiggleverse-ecomm#13 — hand the operator the flotilla provision-bucket gesture for the per-env private GCS bucket at the PPE deploy; DoD: PUC-7 acceptance, INV-12 extended over images, E2E e2e_image_outcomes green, TEL-4/5 emitting, version 0.7.0 shipped through merge + PPE.

Read project_ecomm_clean.md for full context. Gotcha to carry: a CatalogVariant/CatalogImage attribute not in fields{} must be serialized explicitly — the serializer field-loop only walks fields{} (bit SLICE-6's Variant Position; SLICE-7 adds image storage keys / status, same risk class).
