Subject: [PATCH] install ratcheting line-coverage gate at 34% floor (T-90)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

First child of T-89. Codifies "don't make coverage worse" as a
durable pre-push contract before any test-writing children land.

- pubspec.yaml: new `coverage_floor: 34` key. Single source of
  truth for the floor; ratchets up only.
- ci/coverage_gate.sh: parses coverage/lcov.info (LH/LF), reads
  the floor from pubspec.yaml, exits non-zero if integer-truncated
  measured % drops below it. Self-contained awk parser — no `lcov`
  CLI dependency.
- ci/test.sh: flutter test now runs with --coverage, so the gate
  reads fresh data without an extra test invocation. Wall time
  delta is small and stays inside the < 90 s pre-push budget
  (D-29).
- Makefile: new `coverage-gate` target wires the script in;
  `push-check` adds it as a dependency. The .githooks/pre-push
  hook (already wired) picks this up automatically.
- .gitignore: ignore /coverage/ wholesale; the floor lives in
  pubspec.yaml, nothing under coverage/ is committed.

Decision recorded as D-66 (decisions/testing.md). End target is
95%; reaching it is tracked as the rest of T-89's children.

       "description": "Workaround in T-70 / `lib/src/terminal/src/ui/painter.dart` suppresses bold rendering entirely because Flutter`s synthetic bold drifts glyph advance widths and breaks the monospace cell grid. We lose semantic bold (bash prompts, emphasis in TUIs) as a side effect.\n\n**Acceptance:**\n- A bold-weight monospace face ships alongside the regular weight, with verified-equal advance widths at clide`s render size (cell-grid stable on bold).\n- The painter`s `bold: false` override is reverted; bold attributes from terminal escapes render visually bold.\n- Test: render a known-mixed-weight buffer and assert paragraph maxIntrinsicWidth matches the regular-weight measurement (cell drift = 0).\n\n**Options to evaluate:**\n- Re-add JetBrainsMono-Bold.ttf once we`ve verified its advance widths actually equal the Regular file at our cellSize. (We dropped it because the synthetic-bold issue obscured whether the bundled Bold actually matched.)\n- Switch to a variable JetBrainsMono and request a specific weight axis position.\n- Pick a different mono font whose Bold has guaranteed-equal advance (Berkeley Mono, IBM Plex Mono).\n\n---\nRefinement (2026-05-06):\n\nInvestigation showed the perceived over-bolding in the Claude pane was synthetic-bold smearing (Flutter overpaints when no Bold.ttf is registered), not aggressive-but-legitimate bold. Visual A/B confirms a real bold face renders crisp emphasis without smearing. No per-pane renderer config needed.\n\n**Concrete fix shape:**\n1. `pubspec.yaml` (family JetBrainsMono): register `JetBrainsMono-Bold.ttf` with `weight: 700` and `JetBrainsMono-BoldItalic.ttf` with `weight: 700, style: italic`. Files are already on disk under `assets/fonts/jetbrains_mono/`.\n2. `assets/licenses.yaml` JetBrainsMono entry: update `weights_bundled` to `[Regular, Italic, Bold, BoldItalic]` per D-42 (must match what is actually wired into the font family).\n3. `lib/src/terminal/src/ui/painter.dart:198`: revert the `bold: false` override and delete the now-stale comment block at lines 193-195.\n4. Test: render a mixed-weight buffer and assert `paragraph.maxIntrinsicWidth` matches the all-regular measurement (cell drift = 0). If parity fails, the fallback options stay open (variable JetBrainsMono / Berkeley Mono / IBM Plex Mono).\n\nWorkaround comment (`Skip bold rendering — Flutter`s synthetic bold...`) goes away in step 3.",

The downside: any TUI that does its own wheel handling (selection, click-to-position) loses the actual mouse coordinates because all we send is keyboard.\n\n**Acceptance:**\n- The terminal forwards `PointerScrollEvent` and click/drag/release as proper xterm mouse-protocol escape sequences (CSI `M` / SGR variant per the report mode the inner program declared via `?1000h` / `?1006h`).\n- Tested with `vim` (mouse mode `a`), `htop`, `less` — all should respond to mouse selection / click correctly.\n- Falls back to PgUp/PgDown only when the inner program has not declared a mouse mode.\n- The `mouseInput` API on `Terminal` is wired through `Listener.onPointerSignal` instead of being bypassed.\n\n**Why this isn`t the default already:** the bypass was the cheapest fix to get scroll working at all when the multitab/Scrollable ate scroll events. With those fixes landed, the right-shaped mouse forwarding is the proper next step.",

Pre-push hook (already wired via `.githooks/pre-push`) picks this up automatically.\n5. **`coverage/README.md`** — short note explaining the floor file, how to bump it (rule: bump only in the same commit that adds covering tests, with the bump reflecting the measured improvement), and the link to D-66.\n\n**Acceptance:**\n- `make coverage-gate` passes on a clean checkout (floor matches reality).\n- `make push-check` includes the gate.\n- A test deletion would fail `make coverage-gate` (verify by experiment, not just by reading the script — invariant has to actually hold).\n- Pre-push hook runs the gate (verify by attempting a deliberately-failing push and seeing it blocked).\n- `coverage/lcov.info` is gitignored (it's regenerated on every run; only `floor.txt` is committed).\n\n**Out of scope:**\n- Bumping the floor toward 95% — that's the test-writing children's job.\n- Branch coverage — D-66 explicitly excludes.\n- Per-area floors — D-66 chose a single global floor for simplicity.\n\n**Notes:**\n- `lcov` CLI is not installed on this dev machine; parser must be self-contained (awk or python). Don't introduce `lcov` as a dependency of the gate.\n- `coverage/lcov.info` is the standard Dart output path of `flutter test --coverage`. Don't relocate.\n- `flutter test --coverage` runs all tests including `forkpty`-tagged ones, which fail under the flutter test runner (see comment in `test/pty/session_test.dart`); `--exclude-tags forkpty` matches `ci/test.sh`. Forkpty-tagged tests don't currently feed lcov because they run via `dart test`; check whether their coverage can be merged later (separate ticket if not).\n",

Then per-area sweeps — biggest holes first because they move the global number fastest, but each area is its own child ticket with its own scope.\n\n1. **Gate plumbing** (first child) — install the ratchet, lock in current floor, expose `make coverage-gate` and wire it into `make push-check`.\n2. **`lib/src/terminal/` sweep** (second child, by far the largest) — likely splits into sub-children once the area's structure is mapped (parser, buffer, painter, gesture handling, mouse reporting, escape sequences, cell-grid measurement, etc.).\n3. **Per-area sweeps** — claim a child ticket when starting an area; close when the area hits 95%. Order by impact: terminal → widgets → pql → builtin → kernel → daemon → pty → git → ipc → files → extension → editor.\n4. **Final ratchet** — once total ≥ 95%, set floor to 95 and close the epic.\n\n**Out of scope:**\n- Branch coverage (lcov data is weak for branch on Dart; line coverage is the contract).\n- Integration / E2E coverage (only widget + unit feed lcov).\n- `lib/test_app.dart` exclusion: verify in the gate child whether Dart's coverage tooling already excludes it; if not, decide explicitly rather than carve it out silently.\n\n**Cross-references:** D-66 (this epic's decision record), D-29 (pre-push gate scope), \"Own the rendering stack\" guardrail (CLAUDE.md).\n",

Locks in the no-regression contract before any test-writing children land — so subsequent floor bumps are explicit and reviewable.\n\n**What lands:**\n\n1. **`coverage/floor.txt`** — committed file containing today's actual line-coverage number (currently `34` after rounding down from 34.9% to give a small margin against measurement jitter; the gate child re-measures on first install and writes the exact number it observes minus 1 if needed).\n2. **`ci/coverage_gate.sh`** — runs `flutter test --coverage --exclude-tags forkpty`, parses `coverage/lcov.info` (sum of LH / sum of LF * 100), compares to `coverage/floor.txt`, exits non-zero if below, prints the actual percentage either way.\n3. **`Makefile` `coverage-gate` target** — wraps `ci/coverage_gate.sh` for local use.\n4. **`make push-check`** — adds `coverage-gate` to its dependency list. Pre-push hook (already wired via `.githooks/pre-push`) picks this up automatically.\n5. **`coverage/README.md`** — short note explaining the floor file, how to bump it (rule: bump only in the same commit that adds covering tests, with the bump reflecting the measured improvement), and the link to D-66.\n\n**Acceptance:**\n- `make coverage-gate` passes on a clean checkout (floor matches reality).\n- `make push-check` includes the gate.\n- A test deletion would fail `make coverage-gate` (verify by experiment, not just by reading the script — invariant has to actually hold).\n- Pre-push hook runs the gate (verify by attempting a deliberately-failing push and seeing it blocked).\n- `coverage/lcov.info` is gitignored (it's regenerated on every run; only `floor.txt` is committed).\n\n**Out of scope:**\n- Bumping the floor toward 95% — that's the test-writing children's job.\n- Branch coverage — D-66 explicitly excludes.\n- Per-area floors — D-66 chose a single global floor for simplicity.\n\n**Notes:**\n- `lcov` CLI is not installed on this dev machine; parser must be self-contained (awk or python). Don't introduce `lcov` as a dependency of the gate.\n- `coverage/lcov.info` is the standard Dart output path of `flutter test --coverage`. Don't relocate.\n- `flutter test --coverage` runs all tests including `forkpty`-tagged ones, which fail under the flutter test runner (see comment in `test/pty/session_test.dart`); `--exclude-tags forkpty` matches `ci/test.sh`. Forkpty-tagged tests don't currently feed lcov because they run via `dart test`; check whether their coverage can be merged later (separate ticket if not).\n",

 ### Added
 
+- Pre-push coverage gate — `make push-check` (and the
+  `.githooks/pre-push` hook that calls it) now runs
+  `ci/coverage_gate.sh`, which fails if total line coverage drops
+  below the `coverage_floor:` value in `pubspec.yaml`. The floor
+  starts at 34% (today's measured floor) and only ratchets up; the
+  end target is 95% (D-66). `ci/test.sh` now writes
+  `coverage/lcov.info` as a side effect of the unit/widget/golden
+  run so the gate adds no extra test invocation.
 - Staged `dart doc` CI job — generates and uploads an HTML API
   reference for the public `lib/` surface. The step wraps
   `dart doc --validate-links` and grep-fails the build on any warning,

+### D-66: Line coverage gate at 95%, ratcheted from current
+- **Date:** 2026-05-06
+- **Decision:** The pre-push gate runs `flutter test --coverage --exclude-tags forkpty`, parses `coverage/lcov.info`, and hard-fails if total line coverage drops below a committed floor at `coverage/floor.txt`. The floor starts at the actual current coverage (≈35%, dragged down by `lib/src/terminal/`'s 0.4%) and only ever ratchets up. The end target is 95%; getting there is tracked as a campaign of deliberate floor bumps under one epic ticket. **No carve-outs** — code under `lib/` is owned regardless of file-header attribution, including the terminal emulator port. Branch coverage is not gated (Dart's lcov output models it weakly). Lint suppressions to dodge the gate are never acceptable.
+- **Rationale:** A flat 95% threshold today blocks every push; an informational coverage report rots into noise. The committed-floor ratchet makes "don't make it worse" the durable rule and turns the journey to 95% into explicit, reviewed bumps rather than a single overnight cliff. Excluding `forkpty`-tagged tests matches `ci/test.sh` (forkpty + flutter test runner are incompatible — see `test/pty/session_test.dart`).
+- **Cost:** Pre-push wall time grows by `flutter test --coverage` (currently ≈11 s on this tree). Acceptable within D-29's < 90 s budget; reassess if it slips. Floor bumps require an explicit edit to `coverage/floor.txt` in the same commit that adds tests — so contributors can't silently raise it.
+- **Cross-reference:** [D-29](#d-29-pre-push-gate-fast-layer-only).
+- **Raised by:** 2026-05-06 — coverage triage during T-73 follow-up.
