Replace uses of the legacy `gpt-image-2-all` model with `gpt-image-2` and standardize image workflows: no-reference generation uses POST /v1/images/generations, any-reference flows use POST /v1/images/edits with multipart `image` parts. Update SKILLs, generation scripts, decision logs, and docs to reflect the contract change and edits-vs-generations guidance. Apply corresponding changes across backend (api-server match3d/puzzle modules, openai image adapter, mappers, telemetry, spacetime client/module), frontend components and services (Match3D, Puzzle, CreativeImageInputPanel, runtime shells), and add new spritesheet/parser files and tests. Also add media/logo.png. These changes align repository code and documentation with the VectorEngine image API contract and update generation/upload handling (green-screen -> alpha processing, spritesheet handling, and related tests).
Allow history-generated image paths to be submitted where Data URLs were previously required and avoid treating partial/result-page generations as blocking the whole draft. Backend: resolve history /generated-* references via resolve_puzzle_reference_image_as_data_url and convert to PuzzleDownloadedImage; add PuzzleDownloadedImage::from_resolved_reference_image; extend draft handling to apply generated level metadata (auto-naming) and normalize generation_status to treat levels with images as ready. API: add shouldAutoNameLevel to action contracts and use it to request/refine generated level names. Spacetime/module and mappers: normalize completed level statuses when saving/reading so result-page background or per-level generation doesn't mask completed drafts. Frontend: expose resolver helpers, only mark a work as generating when no usable cover or ready level exists, keep level controls enabled during UI-background regeneration, and add tests covering history-image submission, auto-naming, and UI-background/partial-generation behaviors.
Allow local env files to reliably override authentication feature flags (SMS/WeChat) by whitelisting keys in scripts/dev-utils.mjs and adding a unit test. Add SMS checks to scripts/check-api-server-env.mjs. Make server config.parse_bool tolerant of shell-wrapped quoted values (e.g. '"true"') and add tests so SMS_AUTH_ENABLED is parsed correctly when shells supply quotes. Update docs to clarify SMS env behaviour, restart requirements, and add guidance + a CSS fallback for old mobile browsers (QQ/X5) so public cover images render even when aspect-ratio is unsupported. Also include related frontend test and component adjustments and add puzzle onboarding handlers/endpoints in server-rs/crates/api-server/src/puzzle.rs.
Backend: stop treating background music as a required draft asset and remove auto-submit/plan for background music; load persisted generated UI/assets into Match3D agent session responses (added helpers to resolve profile id and fetch existing generated assets). Frontend: make Match3D result preview reuse runtime UI styles, unify runtime settings entry, update PuzzleRuntime to apply immediate pointermove transforms (disable drag transition), use SVG clipPath for merged piece rounding, ensure PuzzleRuntimeShell supplies platform theme classes, and adjust related tests. Docs & logs: update decision log, pitfalls and product docs to reflect these changes.
Delete a large set of outdated documentation (many files under docs/ and .hermes/plans/, including audits, design, prd, technical, planning, assets, and todos). Update and consolidate .hermes content: refresh shared-memory pages (decision-log, development-workflow, document-map, pitfalls, project-overview, team-conventions) and several skills/references under .hermes/skills. Also modify AGENTS.md, README.md, UI_CODING_STANDARD.md, docs/README.md and .encoding-check-ignore. Purpose: clean up stale planning/audit material and keep current hermes documentation and related top-level docs in sync.
