 - Markdown publish defaults require render outputs (`transcripts/final.md` and `transcripts/final.trimmed.md`).
 - Restore requires configured object storage and committed remote current state.

 # Roadmap: Render Stage
 
-Status: Planned

+## Render markdown source missing
+
+Symptom:
+
+- analyze or publish fails because `narratio.transcript.final_markdown` or `narratio.transcript.final_trimmed_markdown` is unavailable.
+
+Likely causes:
+
+- render stage was not executed after transcript changes;
+- render stage failed before producing canonical markdown outputs.

+Diagnostics:
+
+```bash
+narratio session status 2026-04-04
+narratio run-stage render 2026-04-04 --force
+```
+
+Safe fix:
+
+- rerun render and then retry downstream stage(s):

+narratio run-stage render 2026-04-04 --force
+narratio run-stage analyze 2026-04-04 --force
