Outcome summary

  • Plain Markdown, literal code and equations render into local static output.
  • Draft and future entries are excluded before rendering and image registration.
  • Offline fixtures exercise snapshot acquisition and candidate-only upload contracts.

Demonstration only. This is sample content describing this repository. It is not a client engagement or a production deployment.

Context

The repository uses plain Markdown, Astro’s build-time Content Layer and a shared Markdown processor. Authors can edit text files without a CMS. KaTeX generates equation markup at build time rather than using a browser-side math engine.

Problem

A publishing workflow needs to preserve authored text while distinguishing public entries from unfinished or future content. Filtering a page listing alone is not enough if unpublished bodies or their exclusive images have already entered the rendering pipeline.

Approach

Validate strict metadata and the complete source-file envelope first. Resolve one publication cutoff, then admit only entries with an explicit draft: false and a publication date no later than that cutoff:

tpublished≤tcutofft_{\mathrm{published}} \le t_{\mathrm{cutoff}}

Draft and future bodies do not reach rendering, storage or image registration. Their metadata and source-file bounds still require validation.

Implementation

The same public Markdown loader renders blog entries and case studies. The app-owned About singleton uses that safe processor too, but has explicit approval instead of an article publication schedule. Markdown is source material, not executable application code.

Even a fence labelled math stays literal:

\notarealcommand{literal}

The local acquisition prototypes validate an exact Git snapshot or a version-pinned S3 manifest and write a private receipt. The workflow prototype separates source acquisition from candidate-only artifact upload; neither operation is a live deployment.

Outcomes

  • Local build checks exercise Markdown, literal code, equation rendering and generated static pages without rewriting the source files.
  • Publication checks exercise draft and future exclusion, including exclusive images and removal from warmed caches.
  • Offline adapters and synthetic CLI fixtures exercise source integrity, bounded inputs and candidate upload/readback contracts without cloud access.

These are qualitative properties of the repository’s local prototype, not client results or measured production improvements.

Limitations

Local fixtures are not evidence of live GitHub, S3, OIDC, IAM, CDN or GitHub Actions execution. Those cloud integrations remain unverified here. Remote reads and candidate writes require separately approved access and external configuration; they are disabled by default.

Candidate upload does not implement live promotion, withdrawals, deletion or rollback. A draft flag controls generated output, not who can read the source repository. Public deployment and editorial permission remain separate from successful local validation.
