All completion criteria verified. Final report: **Phase 104 — final verification pass: all green** - Verified (no code changes needed): single-line ellipsized `.suggestion-chip` CSS + deleted `.maybe-try` override, `renderChips` full-text `title` + `aria-label`-when-clipped, `maxlength="4000"` + `#char-count` counter + `handleSend` over-cap guard, unit pins file, schemas boundary pins, dedicated E2E suite. - E2E (isolation): `uv run pytest tests/e2e/test_chip_sizing_question_cap.py -v --no-cov` → **6 passed**; regressions: `test_suggestion_chips.py` 8 passed, `test_pinned_composer.py` 4 passed, `test_responsive_polish.py` 7 passed, `test_chat_history.py` 5 passed. - `uv run pytest` → **2102 passed**; `--cov=app` → **99%** (>90%); `uv run ruff check . && uv run pyright` → clean, 0 errors. - Criteria: chip E2E (single-line, clipped, title+aria-label full text) ✅; paste caps at exactly 4,000, send streams, counter hides ✅; programmatic 5,000-char fill → banner, no turn, text kept ✅; 4,000/4,001 boundary pinned + HTML maxlength == JS constant cross-file pin ✅. - Diff scope: `frontend/`, new unit file, `tests/unit/test_schemas.py`, new E2E file, phase files — **no `app/` diff, no migration, no `shared.js` diff**. - Deviations: 4 regression test files touched — 2 genuine DOM-pin conflicts from the new `#char-count` child (explicitly anticipated by the overview) + 3 documented **pre-existing E2E flake fixes** (smooth-scroll race, tab-walk heuristic, 10 ms timeout), each verified pre-existing on the pre-phase-104 tree. - No commit made (harness commits per the execution protocol override). - Next pending phase: `98_sync_summary_visibility`.

"""Unit: schema boundary caps for the saved-chat surface (phase 83, task 01).
|
||
|
||
The first schema-boundary suite: every A1 cap in ``app/schemas.py`` is
|
||
pinned at BOTH boundaries — a value exactly at the cap validates and one
|
||
past it raises a pydantic ``ValidationError`` naming the offending field
|
||
(the 422-shaped boundary response, house style, phase 56 precedent).
|
||
Plus the regression pin: a realistic ``bor.chat.v1`` payload validates
|
||
cleanly and round-trips ``model_dump()`` (the stored-shape contract —
|
||
the caps added value bounds only, no key/shape change).
