# OpenPresentation status — September 15, 2026

The public JSON/slide demo and reusable authoring foundation are available.
Shared headers/footers are validated on main. Four unfinished shaping prototypes
are preserved on remote archive branches and tracked in the roadmap; their
original PRs conclude with documentation/evidence changes only.

Read the [current handoff](handoff-2026-09-15.md),
[next-agent prompt](next-agent-prompt-2026-09-15.md) and
[developer adoption roadmap](plans/developer-adoption-20260915.md).
Earlier dated checkpoints are historical evidence, not current release claims.

| Area | Current state |
| --- | --- |
| Public demo | Home/playground support editable OPF JSON, live preview, preview edits back to JSON, contextual catalog choices and normal code-editor assistance. Appearance is preserved. |
| Published packages | Core0.10.0, renderer0.8.0, editor0.7.0, PPTX0.8.0 and CLI0.8.0 were confirmed in the registry. This final cleanup publishes no additional versions. |
| Developer foundation | Schemas/catalogs, six agent skills, contextual lint/contracts, source-preserving edits/undo, composition/pagination, preview and supported exports exist. Feature and platform limits apply. |
| Shared headers/footers | Core79, renderer20, editor17 and PPTX34 are merged with passing main CI. This increment needs new coordinated versions and consumer adoption. |
| Font shaping/prepared editing | Core83, renderer21, editor21 and PPTX35 retain complete prototypes on archive branches. Final PR diffs contain roadmap/evidence only. Linux native-width failures and an editor packed-test assertion remain recorded, not waived. |
| Native PowerPoint | Acceptance is separately tracked in core issue87. Serialization and self-import do not certify Office. |
| Production checks | Latest retained deployed checks passed 26 main-site, five gallery and ten pptx.dev workflows. See the handoff for commits/evidence. |

The original twenty-PR queue comprises eleven accepted dependency updates,
four accepted furniture increments, four roadmap-only conclusions and one
closed Node26-types update because the ecosystem targets Node24. Check the
linked PR states for final merge/check receipts; merging a roadmap does not
release its archived prototype.

Next: release the accepted increment, provide one independently installable
developer example with current API/version docs, and adopt shared behavior
across the public sites. Broader font/IME/bidi coverage, native Office evidence,
layout repair and full visual-editor coverage remain roadmap work. Selectable
vector PDF and general SVG/Mermaid follow font reliability.
