SlideMuse v2.22.0

Added

• Add produce for resumable Page Spec image production: immutable original/output/intent/review snapshots, atomic state commits with recoverable output projection, single-page invalidation and protected-evidence composition.
• Bind thumbnail geometry to source crops and actual overview pixels; strict selection checks reject padded, incorrectly proportioned internal slides. Legacy outer-canvas checks explicitly remain unverified.
• Allow explicit semantic-to-display coverage so charts can carry claims without repeating every semantic field as literal bullets. Mandatory visible values remain checked; semantic coverage needs actual review.
• Record original/final resolution and explicit upscaling, separate measured phase durations and user waits, and preserve unknown historical timing.
• Reject numeric substring false positives such as treating 132% as the required 32%; keep notes-only changes from invalidating approved images.
• Align both README languages and user guides with role-aware density exceptions instead of a universal bullet quota.

SlideMuse v2.21.0

Changed

• Replace the universal bullet quota with role-aware density defaults and explicit exceptions; reconcile prompts and remove the unsupported total-flow claim from the example.
• Add shared content checks, Page Spec adapters for generation/rebuilding, and hash-bound generated-image observations. These checks do not authenticate sources or prove visual quality.
• Guard generation assembly against unfinished/missing/extra pages, changed images/prompts, stale reviews and aspect-ratio changes; preserve exact embedded image bytes and notes, and retain prior PPTX on failure.
• Keep old frozen Page Specs readable. Legacy generation jobs without a content contract report that content was not checked.

SlideMuse v2.20.0

Added

• Adopt a typed density floor for outlines: every page declares one of 12 layout roles, and every content page carries 3-5 distinct supporting points with per-role required content and a page-budget rule. Revises the previous "no bullet count is judged" statement, which was the main density gap.
• Add the matching Page Spec contract: slides[].role accepts the same 12-value enum and slides[].key_points accepts 3-5 unique non-empty strings. Older drafts and frozen samples without the fields stay readable and are not retroactively certified.
• Add a reusable style library: built-in styles ship under vendor/codex-ppt/skills/codex-ppt/references/, user styles live outside the skill install under ${CODEX_PPT_HOME:-~/.codex-ppt-skill}/references/, both are discovered by directory scan, and a same-name user file takes priority.
• Integrate the complete pinned codex-ppt image-generation backend under slidemuse.py generate with prepare, status, dispatch, result, blocker, assemble, chroma and runtime. Upstream MIT attribution and pinned source hashes are verified by generate capabilities --verify-source.

Changed

• The outline gate now requires reporting the outline location, page count, layout-role list and source-image-to-slide mapping, and stating that no slide image or PPTX exists yet. Page Specs, style overviews, generation prompts and final images stay forbidden until the content version is approved.
• Keep the Page Spec route unchanged; the generate backend is an alternative S5 pipeline with its own artifacts. One task uses one source of truth: slide_jobs.json is not a page-spec.json, prepare never calls an image model, and every final slide image still comes from the confirmed host image backend.
• Provide --with-generate for isolated optional dependencies, and generate --offline for local job, status, recording, assembly and chroma-key work that ignores user config and credentials.

Fixed

• Mark scripts/editable_backend.py and scripts/generate_backend.py executable so Linux runners stop reporting EXE001; both files carried a shebang while committed as 100644, which had kept the ubuntu lint step red since the reconstruction backend landed.
• Add requirements-generate.txt to the development requirements so the CI environment installs filelock; without it the generation-backend tests failed with ModuleNotFoundError.
• Re-record all vendored source hashes on an LF (git-blob) basis and verify them with newline normalization. The previous CRLF-basis hashes could never match on Linux checkouts, so every capabilities --verify-source integrity test failed on ubuntu while passing on Windows.
• Import pymupdf directly in the vendored PDF normalization instead of the deprecated fitz shim. Newer PyMuPDF versions print a deprecation warning into captured stdout, which made rebuild prepare misread the deck_manifest.json path and fail PDF normalization tests.
• Accept the standard fonts-liberation path in the vendored slide-layout test font lookup so Linux CI runners with that package installed always find a scalable font.

SlideMuse v2.18.0

Added

• An optional preserve_asset Page Spec contract binds independent evidence images to SHA-256 hashes and exact, aspect-preserving regions in final lossless slides. Validation rejects changed source files, altered evidence pixels, overlaps, cropping and transparent evidence.
• Image-deck exports with protected evidence reject downscaling and JPEG re-encoding. The release package includes the validator module and evidence-asset guide.
• Regression cases cover source drift, evidence-pixel changes, surrounding-page edits, aspect ratios, paths, overlap, transparency and preservation in exported PPTX media.

Changed

• Research maps, experiment screenshots and precise charts default to original-asset preservation or data-driven plotting, with generated illustrations explicitly identified as such.
• Production calibrates one representative final slide before continuing, requires complete observations for critical visible text, and separates evidence fidelity, chart geometry and presentation readability checks.
• Timed presentations distinguish planned timing from actual rehearsal and distinguish short prompts from full speaker scripts. New production tasks record generation, failure and repair events as they occur.

Scope

• Pixel checks cover only declared protected regions and do not authenticate the source or validate the underlying research. Existing Page Specs remain compatible and are not retroactively certified.
• Image-based production, the four-style selection workflow and optional editable reconstruction remain supported. Workflow changes do not claim a measured reduction in production time or error rate.

SlideMuse v2.17.0

Added

• A dependency-free slidemuse.py entry point for common existing tools, preserving arguments, working directory and pipeline exit codes while selecting the local isolated Python.
• Read-only runtime diagnosis with structured JSON, minimum-version and bounded import checks, shared renderer discovery, and actionable repair commands even when dependencies are missing.
• Bilingual CLI documentation, structured bug/feature forms and a pull request template with reproduction, validation and compatibility context.

Changed

• Installation includes the unified entry point and CLI guides; package and relocation regressions exercise the installed commands.

SlideMuse v2.16.3

Changed

• Replace the README hero's transportation cover with Weld Inspect and its architecture slide with the second red-and-gold showcase image, the ceramic restoration process page.
• Keep Snowline Watch in the hero and update both READMEs' descriptions and image cache version for the new selection.

SlideMuse v2.16.2

Changed

• Refresh the bilingual README hero with a light background, prominent SlideMuse wordmark and presentation cards based on the existing transportation, glacier-inspection and manufacturing showcases.
• Include the lossless WebP hero in the release package and update both READMEs to use the same asset.

SlideMuse v2.16.1

Added

• A public six-slide editable IRENA sample with image/native decks, four independent editing exercises, source PDF, portable inputs, before/after previews and a PowerPoint-export comparison video.
• A complete sample archive containing pinned runtime scripts and a reproduction command that checks native objects, embedded chart workbooks and speaker notes.
• Bilingual guides and homepage download links, with historical independent acceptance and current rebuild verification recorded separately.
• The installer includes the public sample when present; packaged-install regression rebuilds all six decks from the installed files.

Scope

• The sample covers selected 2024 statistics and the original 2025 report-time scenario. Edited table/chart pages explicitly identify synthetic values.
• Reproduction starts from approved images and structured inputs. Native fills and chart axes differ visually from the image version as documented.

SlideMuse v2.16.0

Added

• Bounded renderer subprocesses with configurable timeout, limited safe retries and ownership-checked PowerPoint cleanup that preserves pre-existing interactive sessions.
• Automatic render-cache fingerprints for renderer executable bytes, installed fonts, system and Python dependency versions.
• Optional actual PowerPoint text/table bounds and text-overlap diagnostics, cached with page evidence and surfaced as actionable review tasks.
• Six-page real-backend regression controls and a dedicated LibreOffice/Poppler CI job with exported images.
• Append-only production event logs with explicit generation calls, revised pages, measured review time, wall time and preserved first/final delivery outcomes.

Fixed

• A shared BOM-tolerant JSON reader keeps Page Spec, Scene, data bindings and review evidence consistent throughout validation and delivery.
• Visible numeric dependency changes invalidate only the relevant pages and their transitive provenance; unrelated rendered pages and genuinely recorded reviews remain reusable.

Scope

• PowerPoint measurements are diagnostics, not automatic visual approval; grouped/rotated text and chart labels still require visual inspection.
• Production metrics cover explicitly recorded events only; missing times remain unknown, and repaired final success does not erase first-delivery failure.

SlideMuse v2.15.0

Added

• Conservative native text layout estimates in editable compilation, object auditing and delivery scorecards, including individual table cells and grouped objects.
• Page/element-specific Chinese overflow tasks in pipeline summaries and the existing review panel. Explicit current visual review resolves tasks while retaining estimates in reports.

Changed

• Reorganize both READMEs around installation and current capabilities, including speaker notes, linked data updates, resumable delivery, and optional review tooling.
• Document rendering prerequisites, prepared-task CLI usage, output files, and pending-review semantics; remove duplicated installation instructions and the fixed installation-time claim.
• Unresolved inheritance, auto-fit, transformed groups and unsupported text layouts remain explicitly unverified. Estimates neither modify content nor replace actual rendering and visual review.
