# 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 13,6)* — `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 45)* — `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 89)* — 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 1213 (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).
