TTP 3.2.4: check that the text arrived whole, and repair it - #6

…raps 2026-09-26 (0024-8368): 156 characters typed into the Claude desktop composer, 21 arrived — the last character of each 16-char chunk, then the whole last chunk — and paste.verify said `observed` because the field had grown. The message was sent like that. - landing.rs compares the field's text with what we typed. Scraps of our text (a subsequence, under 90%) are `Partial`; anything the app itself rewrote or drew is not. - When scraps sit still for 80 ms, the verifier selects them over AX (read back to confirm) and retypes the text over them, once, unless the user moved app, started a recording, or touched the field. `paste.repair` records what it did. - If it cannot, the verdict is `partial`, the full text goes on the clipboard, and the pill says ⌘V (`paste_partial`). - paste.verify now counts hardware and foreign key-downs during the injection and when the user hit Return, to test the interleaving theory next time it happens. - TTP_FAULT_GARBLE=<n> reproduces the incident on a real build. - scripts/inject-bench: the bench that measured injection in the Claude composer (everything lands with focus settled; typing 0 ms after the app regains focus loses the first chunks).

First live test on 0a37392 (0000-1f28): the partial landing was detected ("u dicte ?", 9 of 39) and the clipboard got the text, but the repair stopped at `skipped_no_selection`. The selection was read back straight after being set, and Chromium applies it asynchronously in the renderer, so the read still answered the old caret. Poll the read-back for up to 150 ms, off the async runtime, and say which step failed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
