Extend the CLI feedback reproduction packet (#2498) with a fifth
mandated field, `COMPOSITION_STRUCTURE:`, and enforce presence of
`REPRO COMMAND:` / `COMPOSITION_STRUCTURE:` at feedback-submit time.
- Skill + reference now specify `COMPOSITION_STRUCTURE:` — a
privacy-preserving structural anatomy (element census + attribute
presence + timeline shape + delta + defect location) — required for
any rating <=7 that describes a visual defect.
- `buildCompositionCensus()` + `renderCompositionCensusBlock()`
auto-fill the block from composition HTML so agents don't ask the
human user to hand-count `<video>` / `<img>` / sub-comp mounts.
Counts + presence flags only — no file paths, no src URLs, no user
text.
- `hyperframes feedback` soft-warns (never blocks) when a non-10
`--comment` is missing `REPRO COMMAND:`, and when a rating-<=7
visual-defect comment is missing `COMPOSITION_STRUCTURE:`. The
warning points at the auto-census helper so agents remediate
themselves.
- `coreSkillContent.test.ts` locks the new literal in both the skill
and the reference file, following #2498's pattern.
Extends #2498. Follow-up: no change to `doctorSummary` generation, no
change to the feedback-submission API endpoint, no refactor of
#2498's doc-content Jest test.
