|
||
|
||
> App: ecomm
|
||
> Start: 2026-06-12T02-07 (PST)
|
||
> Type: planning-and-executing
|
||
> Claude-Session: 2c8ed539-d087-409e-ad4d-effec7f8d6b3
|
||
> Status: **FINALIZED.**
|
||
> Posture: autonomous (yolo)
|
||
> Outcome: SLICE-8 Shopify dialect SHIPPED to PPE — v0.8.0, PR #32, Feature #13 closed.
|
||
|
||
## Launch prompt
|
||
|
||
`/goal SLICE-8` — Shopify dialect (closes Products story #13), per SD-0002 §7.2.
|
||
|
||
## Plan
|
||
|
||
> Anchor: design `wiggleverse-ecomm-content/specs/SD-0002-products-bulk-csv-import-export.md` (R2a, ELIGIBLE) — SLICE-8 §7.2; closes story #13.
|
||
> Posture: autonomous (yolo)
|
||
|
||
**SLICE-8 — Shopify dialect + public format docs → completes PUC-6, PUC-11**
|
||
|
||
Ships (per SD-0002 §6.5.1 / §7.2):
|
||
1. **Header-set dialect detection** — `detect_dialect()` recognizes Shopify's
|
||
exact header set → `"shopify"`, else `"canonical"`; honest fail to canonical
|
||
(never misparse) per §7.4 risk row.
|
||
2. **Shopify→canonical mapping** at the codec boundary (INV-17): rename Shopify
|
||
headers to canonical before the known/unknown split; Shopify columns with no
|
||
canonical home are reported as **not-imported** (the `unknown_columns`
|
||
warning). Exhaustive mapping pinned as a fixture (§6.5.1).
|
||
3. **Preview UI** — "Shopify product CSV — mapped" banner + not-imported
|
||
columns warning band on ImportPreview (PUC-6).
|
||
4. **DOC-2** — CSV column reference (every column; dialect notes), app-served,
|
||
source in framework repo.
|
||
5. **DOC-3** — finalize `sample.csv` (variants + images worked examples) +
|
||
link from import screen (PUC-11).
|
||
6. **E2E** `e2e_import_shopify_dialect` — unmodified Shopify fixture → mapped
|
||
banner + not-imported warnings → confirm → run completes (DoD).
|
||
7. Unit tests (detection, mapping table, INV-10 partial-never-deletes over
|
||
Shopify); §12 traceability audit; DOC-4 dialect-adapter notes; version bump;
|
||
PPE deploy + E2E green; close #13.
|
||
|
||
## Deferred decisions
|
||
|
||
_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._
|
||
|
||
1. **Dialect detection by signature + canonical veto, not exact header set.** The
|
||
spec §7.4 mentions a possible `unknown_dialect` state; I implemented signature
|
||
detection (Shopify-only columns) with a **canonical-distinctive veto** instead
|
||
of a third dialect state. A file with any canonical-distinctive column
|
||
(`Description`/`Variant Cost`/`Variant Weight`/`Google Product Category`/…) is
|
||
canonical; ambiguous/hybrid headers fall through to canonical (warns, never
|
||
corrupts). Robust to Shopify's market-column variance. Adopted after an
|
||
adversarial review found the naive signature-only detection could misread a
|
||
canonical file carrying a stray signature name (e.g. `SEO Title`) and silently
|
||
corrupt (`Type` dropped, weight kg→g). No `unknown_dialect` state added.
|
||
|
||
2. **`Variant Grams` → `Variant Weight` with unit forced to `g`.** Shopify's own
|
||
`Variant Weight Unit` display column is *not imported* (warned). Lossless in
|
||
mass (grams is exact). Weight + synthesized unit move together on clear. Revisit
|
||
if merchants need kg/lb display fidelity round-tripped.
|
||
|
||
3. **DOC-2 served as raw Markdown** (`text/markdown`) at `/api/products/columns.md`,
|
||
mirroring how DOC-3 `sample.csv` is served — not a styled HTML page. Satisfies
|
||
"app-served, source in framework repo"; styled rendering is a future enhancement.
|
||
|
||
## Notes / incidents
|
||
|
||
- The adversarial-review **subagent ran `git checkout` and left the working tree on
|
||
`main`** mid-session (commits were safe on the feature branch). Recovered by
|
||
checking the branch back out. Worth a plugin-feedback note: review subagents
|
||
should not switch branches in the shared checkout (the §5.4 worktree hazard, here
|
||
caused by a *subagent* rather than a second session).
|
||
- The repo `.venv` was **stale** at session start (missing Pillow + google-cloud-storage
|
||
from SLICE-7); re-synced from `backend/requirements.txt`.
|
||
|
||
## Pre-state
|
||
|
||
- On `main` @ 8ed9b25 (SLICE-7 merged, v0.7.0 live on PPE). Clean, pushed.
|
||
- SD-0002 SLICE-5/6/7 delivered; SLICE-8 (Shopify dialect) the last slice, no new
|
||
Solution Design needed (it's part of the approved SD-0002). Anchor eligible R2a.
|
||
- Stale `--INPROGRESS` placeholder SESSION-0027 noted (orphaned, predates shipped
|
||
0034) — not a live concurrent session; no worktree mandate triggered.
|
||
|
||
## Session arc (turn-by-turn)
|
||
|
||
1. **Init** — classified `/goal SLICE-8` as planning-and-executing; claimed session
|
||
0035; verified clean `main`; resolved app/content; eligibility gate ELIGIBLE
|
||
(R2a, anchored on SD-0002). Read SD-0002 §6.5.1 / §7.2 SLICE-8.
|
||
2. **Map** — Explore agent mapped the existing import codec/pipeline/UI. Key find:
|
||
the `detect_dialect` seam, `unknown_columns` threading, and `dialectLabel` UI
|
||
helper already existed from SLICE-5 — SLICE-8 fills them in; the frontend
|
||
not-imported banner already renders. Bulk of work = backend detection + mapping.
|
||
3. **Plan** — wrote `docs/superpowers/plans/2026-06-12-slice-8-shopify-dialect.md`
|
||
(writing-plans). Branch `slice-8-shopify-dialect`.
|
||
4. **Execute (9 tasks, inline TDD)** — (1) `dialect_shopify` adapter; (2) wire into
|
||
`codec.parse_csv` (header rewrite at the INV-17 boundary + grams→weight-unit
|
||
synth); (3) exhaustive mapping fixture; (4) INV-10 over a partial Shopify import;
|
||
(5) frontend label + format-help links; (6) DOC-2 `columns.md` + route; (7) DOC-4
|
||
notes; (8) E2E `e2e_import_shopify_dialect`; (9) v0.8.0 bump + full gate.
|
||
Each task committed; e2e selector race fixed (asserted an unambiguous
|
||
not-imported column).
|
||
5. **Adversarial review** — a review subagent found two real HIGH findings
|
||
(canonical-file misdetection → silent corruption; dual-named-column shadow).
|
||
Fixed with the **canonical-distinctive veto** + tightened grams synthesis
|
||
(commit a851d35); +4 tests. (The subagent also left the tree on `main` — see
|
||
incidents.) Re-ran full gate + E2E green.
|
||
6. **Ship** — push → PR #32 → merge (e2d8b5c); tag v0.8.0; `flotilla-core deploy
|
||
ecomm` 9/9 green (deploys.id=45); PPE `/healthz` → 0.8.0, DOC-2 serving;
|
||
stamped `release/2026-06-12T02-41`; closed Feature #13.
|
||
7. **Finalize** — archived the plan to content `plans/`; updated memory; published
|
||
this transcript.
|
||
|
||
## Cut state
|
||
|
||
- `main` @ e2d8b5c, **v0.8.0 LIVE on PPE** (https://ecomm-ppe.wiggleverse.org).
|
||
Tags `v0.8.0` + `release/2026-06-12T02-41` pushed. Feature #13 closed.
|
||
- **SD-0002 fully delivered.** Local `main` synced + clean; feature branch deleted.
|
||
- Gates green: `check.sh` (lint-imports + backend pytest + frontend build + 22
|
||
vitest) and `e2e.sh` **8/8**.
|
||
- Not shipped to **prod** (prod doesn't exist yet — SLICE-4 prod stand-up, an
|
||
operator-gated flotilla gesture, closes Feature #1 and would let v0.5–0.8 ship).
|
||
|
||
## Next-session prompt
|
||
|
||
```
|
||
/goal Brainstorm and write the Solution Design for Products list + read-only detail (wiggleverse/wiggleverse-ecomm#14, P1 feature under epic #12): list view with sort, search, and column selection (defined defaults) over the SD-0002 catalog, plus a read-only product detail view; reusable data-table-as-Common-Component is a non-binding solution note. type/feature → needs its SD before any plan (§4.3 R3); author section-by-section in wiggleverse-ecomm-content/specs/ (next is SD-0003), graduate at finalize.
|
||
```
|
||
|
||
Operator may instead prioritize the **SLICE-4 prod stand-up** (closes Feature #1,
|
||
unblocks shipping v0.5–0.8 to prod), the **#23 rebrand SD**, or the **manual PPE
|
||
image walk** (SLICE-7 GcsObjectStore first real exercise) — confirm at session open.
