Session 0030.0 — Transcript

App: ecomm Start: 2026-06-11T07-44 (PST) · End: 2026-06-11T14-01 (PST) Type: brainstorming Anchor: wiggleverse/wiggleverse-ecomm#13 (type/feature, priority/P1; parent epic #12) Claude-Session: 1137cc4a-8566-421a-b6c9-6cef5f481d11 Status: FINALIZED

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 17). 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, Option13, Variant SKU/Barcode/Price/ Cost/Weight/Volume/Tax/Inventory/Position, Image Src/Position/Alt, Variant Image, Component 110 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. §34 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. §6.16.4 invariants INV-10…18 (numbering continued app-wide after SD-0001's 19), 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. §6.56.10 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-14); rollout honest about missing prod; risks led by diff-engine edge cases. Approved.
  16. §§811: 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. §§1214 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 §§45). 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.mdapproved / graduated, v0.3.1, content main @ 065722c. 1,429 lines, §§114 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.
