## Launch prompt

```
/wgl-brainstorming develop the Solution Design for Feature #13 (Products: bulk CSV import/export — the only data mechanism in the MVP), anchored on https://git.wiggleverse.org/wiggleverse/wiggleverse-ecomm/issues/13 - ask me a lot of questions about the scope and UX patterns on this one
```

## Plan

> Anchor: #13 (wiggleverse/wiggleverse-ecomm — Products: bulk CSV import/export)

Brainstorming session: explore the scope and UX of Products bulk CSV
import/export (the MVP's only product-data mechanism… amended by capture 0031
mid-session, see arc) and author its Solution Design, section by section with
operator review at each boundary, in `wiggleverse-ecomm-content/specs/`.
Operator asked for heavy question-driven scoping.

## Pre-state

- App main @ 6b405a0 (clean, pushed). PPE live at v0.4.0
  (https://ecomm-ppe.wiggleverse.org); prod not yet stood up.
- Content repo main @ bfadf63; `specs/` held only SD-0001.
- Tracker: epic #12 with Features #13 (this anchor) / #14 / #15 captured
  0025/0026; #13 had no Solution Design (the §4.3 gate this session lifts).
- Two concurrent sessions in flight at claim time: 0027, 0029 (and a capture
  session 0031 ran concurrently during this one) → worktree isolation
  mandatory.

## Arc, turn by turn

1. **Init (wgl-brainstorming Steps 1–7).** Claimed **0030** (dry-run peek
   surfaced 0027/0029 in-progress → warned, proceeded per autonomous
   default; `--type brainstorming`). Baseline verified clean/pushed.
   Resolver: CONTENT/ROADMAP → `wiggleverse-ecomm-content`; no BDD repo for
   this app. Eligibility gate: **#13 ELIGIBLE** (`type/feature`, R1).
   Worktree: content repo `.worktrees/session-0030`, branch `session-0030`
   (`.worktrees/` added to content `.gitignore` on main first — a push race
   with a concurrent session required one rebase).
2. **Inputs.** Issue #13 + siblings #12/#14/#15 read from the tracker;
   SD-0001 skimmed for house style + platform surface; solution-design
   TEMPLATE/GUIDE + claude-design-vs-code rubric read; prototype corpus
   product-CSV scenarios (rfcs 11-05-0032…0037) pulled as the reference.
3. **Scoping Q&A round 1 (scope/format).** Operator supplied the full
   **canonical column set** verbatim (Shopify-flavored superset: Handle,
   Title, Description-HTML, Vendor, Type standalone/kit_*, Google Product
   Category, Tags, Status, Published, Option1–3, Variant SKU/Barcode/Price/
   Cost/Weight/Volume/Tax/Inventory/Position, Image Src/Position/Alt,
   Variant Image, Component 1–10 SKU/Qty). Decisions: canonical + **Shopify
   import**; **upsert-only, no deletes**; kits = **seam only** (#15 owns
   semantics). Visual-companion offer declined (text only).
4. **Round 2 (UX patterns).** Sync import with async seam;
   **validate-all → preview → confirm with per-record drill-in diffs**
   (operator's custom answer — show exactly what changes per record);
   row errors on-screen only (no email); UI = **Products page created by
   this SD** (#14 fills the list in).
5. **Round 3 (data semantics).** Variant identity = **option-value combo**
   (SKU = correctable data — deliberate divergence from corpus 11-05-0035);
   images = **fetch-and-host**; dialect **auto-detect by headers**;
   **~5k row** sync cap.
6. **Round 4 (edges).** Image timing = commit-rows-then-fetch (operator
   asked how fetch failures + quality surface → proposed import-run records
   w/ per-image status + renditions; operator approved with **reject
   low-res** instead of accept-with-warning); unknown columns =
   warn-in-preview, ignore; export = **full catalog + status filter**;
   format docs = **sample CSV + column reference**.
7. **§1 Business Context** drafted (solution-agnostic; BUC-2
   preview-consent elevated to a business use case, OHM consent & agency),
   committed/pushed; **operator: "looks good."**
8. **§2 Solution Proposal** (the decided shape end-to-end + alternatives +
   non-goals); flagged confirm-applies-valid-rows semantics, XLSX-rejected,
   no-image-editing. **Approved.**
9. **§3–4 Personas + PUC-1…11** (Merchant persona reused; full lifecycle
   incl. PUC-10 round-trip-visible and PUC-3a cancel-no-trace; corpus
   divergence flagged at top). **Operator: "looks great."**
10. **§5 UX Layout.** Rubric scored **−1 → Code directly** (recorded);
    4 screens (Products / upload / preview / run detail); two §4 PUCs
    back-patched for consistency (PUC-7 aggregate notice pre-#14; PUC-10
    no-op confirm disabled). **Approved.**
11. **§6.1–6.4** invariants **INV-10…18** (numbering continued app-wide
    after SD-0001's 1–9), architecture (new `products` domain +
    `platform/objectstore` + `platform/images` + in-process image-fetch
    task = the named async seam), data model (6 tables; kit tables
    deliberately absent), 10 REST contracts. **Approved** with two
    operator questions answered next turn:
12. **Operator probe 1 — sync vs image fetches:** answered (catalog
    transaction never waits on images; restart recovery required → §6.9).
    **Operator probe 2 — skip already-imported images:** exposed a real
    bug — exports write hosted URLs, naive diff would re-fetch everything
    and break INV-12. Fixed in-model: **hosted-URL resolution + never
    re-fetch fetched URLs; fetch only new/retry** (→ §6.3, §6.5.3, D-12).
13. **§6.5–6.10** column spec + row grammar + blank-vs-absent semantics,
    Shopify mapping (free-text `Type` warned-not-imported), 4 sequence
    diagrams, NFRs (SSRF guard), decisions table, named E2E scenarios,
    failure modes (deploy-mid-fetch recovery), greenfield migration.
14. **Storage deep-dive (operator-requested).** Catalog = additive tables
    in existing Cloud SQL (no new resource). Images = per-env **private GCS
    bucket** (uniform access, Standard, flotilla `provision-bucket` gesture,
    name via deployment config), tenant-prefixed immutable image-id keys,
    WebP renditions, drafts prefix w/ 1-day lifecycle rule. Serving fork
    presented (app-served vs public bucket vs CDN-now); **operator chose
    app-served + CDN seam** → §6.3.1 + serving endpoint + 2 decision rows.
15. **§7 Delivery Plan**: **SLICE-5 import-spine → SLICE-6 export/round-trip
    → SLICE-7 images → SLICE-8 Shopify dialect+docs** (numbering app-wide
    after SLICE-1–4); rollout honest about missing prod; risks led by
    diff-engine edge cases. **Approved.**
16. **§§8–11**: BO/PM metrics, TEL-1…6 log-event telemetry, SLO-2/3 +
    ALR-2/3 (notify-only, no paging), RB-2/3/4 runbooks, ops (Pillow flagged
    patch-sensitive; bucket backup = accepted pre-v1 risk Q-2), DOC-1…4.
    **Approved ("proceed").**
17. **§§12–14** traceability matrix (audited closed), decisions log
    **D-1…13** + open **Q-1…3**, glossary; self-review pass (placeholder
    scan clean; SLICE-5 DoD telemetry refs fixed; v0.2.0).
18. **Operator dropped a Claude Design hi-fi bundle**
    (`ui/designs/SD-0002-products-bulk-csv-import-export/` — all four
    screens + the wiggleverse `_ds` design-system bundle, built from this
    spec's §§4–5). Committed on the session branch (26 files, matching the
    per-SD convention); **§5.1 amended** to Design → Code (both the −1
    rubric score and the operator's shareable-artifact override recorded;
    bundle = SLICE-5 bootstrap artifact, prose governs; D-14); §5.2 toast
    refinement adopted; v0.3.0.
19. **Finalize.** Status → `approved` (v0.3.1, autonomous posture, every
    section operator-reviewed at its boundary). Content **PR #4 merged**
    (main @ bcdbc18); `submit-spec.sh --status graduated` stamped in place
    (main @ **065722c**). Worktree removed, local+remote `session-0030`
    branches deleted; the operator's untracked design-copy in the canonical
    checkout removed after byte-identical verification; SD linked on #13
    (comment). Memory updated (entry slotted before concurrent 0031's).
    This transcript published last.

## Deferred decisions

None — every judgment call was surfaced in-chat at its section boundary and
operator-reviewed before advancing (the section-at-a-time loop is the review).
Two small ones worth a skim anyway: BO-1's "under an hour of merchant effort"
target is invented (tune in §8 review); §13 D/Q numbering is per-spec while
INV/SLICE/TEL/ALR/RB/DOC numbering continues app-wide — convention noted in
§13's preamble.

## Cut state

- **Spec:** `wiggleverse-ecomm-content/specs/SD-0002-products-bulk-csv-import-export.md`
  — `approved` / `graduated`, v0.3.1, content main @ 065722c. 1,429 lines,
  §§1–14 complete. The content repo is its only home.
- **Design bundle:** `wiggleverse-ecomm-content/ui/designs/SD-0002-products-bulk-csv-import-export/`
  (committed, merged).
- **App repo:** untouched this session (main @ 6b405a0).
- **Tracker:** #13 carries the SD link comment; gate to a
  planning-and-executing session is lifted for SLICE-5.
- **Worktree:** removed; content repo back to a single canonical checkout on
  main; no dangling branches.
- Open questions parked IN the spec (§13): Q-1 currency, Q-2 bucket backup at
  prod hardening, Q-3 resolution-bar numbers (SLICE-7's plan).

## Operator plate

- Nothing required to close this session.
- When SLICE-7 reaches PPE: run the flotilla `provision-bucket` gesture
  (named in SLICE-7's DoD; RB-4).
- Standing next `/goal` remains the SLICE-4 prod stand-up (unchanged by this
  session).

## Next-session prompt

The stored memory `Next /goal:` (SLICE-4 prod stand-up → close Feature #1)
takes precedence and is unchanged. When picking up THIS thread instead:

```
/wgl-planning-and-executing plan and build SLICE-5 (import spine: products domain, canonical CSV codec, diff engine, preview/confirm UX, Products page) per wiggleverse-ecomm-content/specs/SD-0002-products-bulk-csv-import-export.md §7.2, anchored on wiggleverse/wiggleverse-ecomm#13
```

## Session metadata

- Sessions: 0030.0 (this file). Concurrent: 0027, 0029 (in-progress at
  claim), 0031 (capture, ran mid-session — its #25/#14/#12 edits postdate
  this spec's §1.2 framing; no conflict: #25 single-create shares the
  canonical field set with this SD's format).
- Spec commits: 12 on `session-0030` (2cb6ccc…6929467), merged via content
  PR #4 (bcdbc18), graduated @ 065722c.
- Gotcha recorded to memory: Gitea admin token Keychain service is
  `wgl-gitea-token-git.wiggleverse.org` (not `wgl-gitea-admin-token`);
  `security` exit 44 silently short-circuits `&&` chains.
