phase: 165_prose_word_wrap

All verification complete. Final report:

**Phase 165 — Prose word wrap (final verification pass)**
- Verified: `PROSE_FORMATS={txt,text}` + `isProseDoc` (single-site, image arm wins); `renderDocument` three-way branch (md → `.doc-md`, prose → `.doc-prose` text node, else `pre.doc-raw` byte-identical); `.doc-prose` CSS = 72rem column, `pre-wrap` + `overflow-wrap: anywhere`, tokens only, zero literals; `[data-view="pages"]` hide list includes `.doc-prose` as one grouped declaration; phase-116 scrollbar rules intact and modal-scoped; no `innerHTML` in the prose path.
- Tests/lint (all 100% green):
  - `uv run pytest` → **3854 passed** (unit + integration)
  - `uv run pytest --cov=app --cov-report=term-missing` → **TOTAL 99%** (>90%)
  - `uv run ruff check .` → All checks passed; `uv run pyright` → **0 errors**
  - `uv run pytest tests/e2e/test_prose_word_wrap.py -v --no-cov` → **5 passed** (isolation)
  - Isolation regressions: document_viewer 8, image_documents 4, pdf_pages_in_sources 4, pdf_strip_additive_selfheal 5, edit_summaries 4, summary_in_viewer 4, chat_answer_clusters 4, garbage_pdf 3, pdf_support 6, sticky_navbar 3, smoke 3 — all passed
- Completion criteria: image description wraps, full text, both surfaces ✔; `.txt` wraps same way ✔; `py`/`json`/code keep `pre.doc-raw` + horizontal overflow + themed modal scrollbar (E2E negative control + pins) ✔; no innerHTML, AA `--ink`/`--surface` pair ✔; full gates green ✔; commit + phase-dir move are harness-owned (not executed per pipeline rules).
- Documentation: README already updated by task 03 (viewer section + image-docs section); full README/AGENTS.md review found no further inconsistencies — **verified consistent, no changes needed**.
- Notable deviations: `.doc-prose` omits `font-family: inherit` from 00_phase D2's snippet — task 01's authoritative "exact property set" excludes it and `div` inherits fonts anyway (behavior identical). PDF deferral (A4) intact: `format == "pdf"` stays in `.doc-raw`, owner call recorded.
- Next pending phase: `166_hide_empty_answer_bubble`.
