+status: done
+task: Chromium touch modal cancel, two-finger navigation and pen single commit
+updated: 2026-08-19 America/New_York
+enablingTask: false
+parityStateChange: false
+
+## Scope
+
+`InputModalState` is now consumed by both production viewport backends. Touch cancellation clears
+the modal without a Main commit, the transition to two active touch pointers increments
+`navigationRevision` once, and a pen pointerup increments `mainCommitCount` once. Late pen up/cancel
+events do not create another commit. The state is exposed through bounded `data-input-modal-*`
+diagnostic attributes for Chromium evidence.
+
+## Evidence
+
+- `npm --prefix web run build` passed.
+- `npm --prefix web run test:chromium-input-modal` passed: 3 protocol tests plus real Chromium
+  main-thread and OffscreenCanvas scenarios.

+status: done
+task: Text data-block LOCAL_EXACT slice
+updated: 2026-08-20 America/New_York
+
+scope: Blender 5.2 `Text` identity and bounded internal text resource fields through the same generated fixture in desktop and WASM/Main: source content, SHA-256, UTF-8 byte length, line count, path, internal state, dirty state and module flag.
+
+evidence:
+
+- `tools/web/generated/M16-GAP-00024.py` deterministically creates `text:WebGapText` with two text lines and project-relative filepath.
+- Desktop reopen report matches exactly: source hash `668dbf...15f82`, 39 UTF-8 bytes, three stored lines, `//WebGapText.txt`, and stable flags.
+- The reader exports the bounded Text resource while preserving the existing blocked script-source inventory; protocol validation enforces source/hash/size/line budgets.
+- WASM/Main opened the same fixture, matched every desktop Text field, saved and reopened with an identical snapshot, and rejected a truncated Blend without mutating the loaded Main.
