item create/edit: upload remaining gallery images via picture2

[cibernox]

Summary

item create --image a --image b --image c currently publishes listings with a single picture: all files are uploaded to /api/v3/upload/{uuid}/pictures (204 each), but the multipart POST /api/v3/items only has its first image part attached — extra parts are silently ignored. item edit --image has the same problem, plus it can fail with "cannot tell which leaf category … sits in" because the item detail returns a localized taxonomy path that doesn't resolve against the create tree.

Root cause

Wallapop migrated publishing to a server-driven steps wizard (POST /api/v3/steps, LLM-assisted). In the current Angular upload app the gallery is assembled in two phases (upload service, processQueue):

1. POST /api/v3/items carries the payload plus only the first image.
2. The remaining pictures go to POST /api/v3/items/{id}/picture2 — multipart with a plain order field (1-based gallery position) and the image under image.

The old multipart flow that the CLI recorded (2026-09-15) still works for creation, but it now only ever takes the first picture.

Fix

• CreateItem/EditItem send only the leading image in the write call, then upload the rest to picture2 in gallery order (new uploadItemPicture).
• A failed picture upload no longer fails the whole command: it warns (published <hash>, but picture N failed to upload) and still returns the item, so retries don't publish duplicates.
• item edit gains --category <leaf-id> to pin the leaf id and skip taxonomy resolution.
• Fake server implements picture2; TestItemCreatePublishesWithImages now asserts the picture2 call happens.
• Includes a hidden wallapop debug-steps command that was used to explore the steps wizard while diagnosing this (kept in case it's useful; happy to drop it).

Testing

• go test ./... passes.
• Verified against production with a scratch listing: item create with 3 images now yields a 3-image gallery in order, verified via item images + downloading the CDN images and checking each one's content. Scratch listing deleted afterwards.

Happy to rework the picture-upload failure semantics if you'd rather the command fail loudly.

item create and item edit upload the first image with the item write, then send remaining images in order to POST /api/v3/items/{id}/picture2; if an extra upload fails, the command warns and returns the item without propagating the upload error.

• item edit --category <leaf-id> sets the leaf category directly and uses it to validate attributes when attributes are supplied.
• The hidden debug-steps command exposes raw step requests and image uploads; the fake server supports picture2.
• The supplied summary reports go test ./... passes. No current review findings or additional test results were supplied.

Walkthrough

The item edit command adds a leaf category flag and uses the selected category to resolve attributes. Item creation and editing send the first image with the item request, then upload remaining images individually. Upload failures produce warnings without changing the create or edit result. The client adds raw steps API helpers, and the CLI registers a hidden command for raw GET, upload, and JSON POST operations.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to 4deda

The fake server can report one image after a second image is uploaded. This is a bounded testing discrepancy, not evidence that production uploads fail; the PR is mergeable with a fix or explicit follow-up.

Review comments at @internal/cli/debug_steps.go:
- Line 50: Update the input handling around payload in the debug steps flow to
validate the input as JSON and pass it to StepsRaw as a json.RawMessage,
preserving number precision instead of decoding through any and float64.
- Around line 30-31: Validate arguments in the debug-steps dispatch before
calling StepsGetRaw or writeItem: require a path for GET, and require both a
path and at least one filename for upload. Reject incomplete arguments instead
of indexing args[1] or sending an upload with an empty image slice.
- Around line 25-26: Update the debug-steps usage text to show `upload PATH
f.jpg` without the `--` prefix, matching the command’s positional upload syntax;
keep the existing multipart description.

Review comments at @internal/cli/item.go:
- Line 385: Update the category and attribute handling in the command so setting
`in.CategoryLeaf` to `categoryID` is preserved when `--attr` is also set;
resolve attributes against the selected leaf or prevent the attribute path from
replacing it with the listing’s current category.
- Line 437: Validate the --category value in the command flow using the category
flag’s set state: when explicitly supplied, reject values less than or equal to
zero before the edit contract treats the ID as absent or resolves a category.
Preserve the existing “work it out” behavior when the flag is not supplied.

Review comments at @internal/wallapop/publish.go:
- Around line 139-147: Update CreateItem and EditItem so uploadItemPicture
failures remain reported through Notice but do not become returned errors after
the listing write succeeds. Remove picErr tracking and return the published item
with nil error in both flows.

Reviewed and fixed the gallery failure contract, explicit category plus attributes, non-positive category IDs, debug argument panic, upload help syntax, and large JSON integer preservation. Full Go tests, vet, staticcheck, build, and generated-reference checks pass locally. Vercel preview is excluded from readiness because it requires fork-author deployment authorization; repository CI remains required.

Count the default image before adding a picture.

When an existing Item has Images == 0, fakeImages reports one default image. A successful upload changes the count to 1, so the fake API still reports only one image. Set the stored count to 1 before adding the new image count.
