v4.5.0 — Editable PPTX mode

[4.5.0] - 2026-08-12

Added

• Editable PPTX mode (paperbanana-slide-deck v1.3.0) — new explicit mode router scripts/build-deck.ts (--mode image|editable is required; editable reads <deck-dir>/slide-spec.json and never falls back to image mode). The editable renderer (scripts/editable/) validates the portable v1 slide contract (Ajv 2020-12 schema + bounds, [Sources] notes, duplicate-ID, asset-existence, and SHA-256 pin checks) and emits native PowerPoint text/table/chart/shape/line objects with PptxGenJS 4.0.1 — nothing is rasterised. Includes a layout-only group container whose children are validated against the group box and emitted individually (PptxGenJS exposes no native group API).
• Preview-only Critic adapter — scripts/editable/review-editable.py sends rendered PPTX previews (slide-NN.png) through PaperBanana's CriticAgent (DiagramType.SLIDE) and maps every suggestion back to slide-id/element-id (unmatched → slide-id/unmapped). It imports PaperBanana only inside main(), supports --dry-run (no import, no network), never modifies the PPTX or previews, and fail-closes with status: "unreviewed" + non-zero exit on provider failure.
• Authoring contract doc — references/editable-slide-spec.md: 13.333×7.5 in coordinate system, element field tables, theme palette (paperbanana-parchment / paperbanana-clean), asset hash rule, [Sources] rule, build/preview/Critic commands, the editable-vs-SVG boundary, and the full passing fixture.
• Tests and CI — Bun regressions for legacy image mode (single <p:pic>, notes part, no on-slide prompt text), editable OOXML structure (native chart + notes + object names), group bounds, and router fail-closed behavior; Python unittest for Critic suggestion mapping. CI now installs Bun, runs bun test, unittest discover, and py_compile on the adapter.

Changed

• Repository-owned legacy merger — scripts/merge-to-pptx.ts moved into the plugin from the audited active skill copy (pre-extraction SHA-256 4a589f90…), refactored only at the buildImageDeck() seam; CLI usage, filename pattern, sort order, 16:9 cover behavior, prompt-note behavior, default output naming, and logs are unchanged.
• SKILL.md — new Phase M (explicit deck-mode selection recorded in deck-mode.txt; ask when ambiguous, never infer from file presence) and an Editable Mode Workflow section (text-free assets → spec → validate → build → render previews → Critic → revise spec → rebuild). The image-mode workflow is unchanged.
• Versions — plugin manifest paperbanana-slide-deck → 1.3.0; marketplace metadata → 4.5.0. Both READMEs document the two-mode workflow bilingually.
