ox-pr-header

You do not hand-write this markup — ox pr header does. A GitHub PR body is sanitized harder than repo markdown (no CSS, no styled tables); the line is built from the exact primitives that survive (<picture> wordmark, <a> links, <sub> caption). Hand-authoring it is how it silently renders as a bordered table or a vanished wordmark. Run the command and paste its output verbatim.

When

At PR-creation time, only when SageOx-delivered team context measurably shaped the work (your contribution score is not none). If SageOx did not shape it, omit both the header and the SageOx-Session: trailer — publishing SageOx credit for work it did not influence is the fabrication #809 guards against. When it did shape the work, the header is the top of the body and the SageOx-Session: trailer stays the last line (they serve different readers: the header a human, the trailer the reconciler).

How

1. Gather what the PR credits (you already hold this from your session):

   • the plan ids you saved (pln_…), if any;
   • the enrichment counts from ox plan enrich (related sessions / concurrent edits), if any.

2. Run the command — the current session is auto-linked; add plans + enrichment:

   ox pr header \
     --plan pln_4d8e2f --plan pln_1a6b9c \
     --prior-art 2 --collisions 1
   

   --session <url|ses_id> adds/overrides sessions (default: the live session). --no-stat drops the whisper. --style text|image|auto follows ox config (pr_visuals.style) by default. --json returns the markup plus resolved inputs for verification.

3. Paste the output as the FIRST lines of the PR body, above your summary. Write the body via a file, never a heredoc — a heredoc mangles the markup:

   ox pr header > body.md
   printf '\n' >> body.md
   cat description.md >> body.md   # your written summary
   # ...keep the SageOx-Session: trailer as the last line...
   gh pr create --body-file body.md
