An agent's numbered list wraps its URL, and the link opened a PREFIX of it:
1. https://github.com/users/someone/packages/container/p
ackage/thing
opened `…/container/p`. The provider already stitched hard wraps — Ink emits a real
newline, so nothing is flagged `isWrapped` and a row that fills the last column is
taken as continuing — but it joined the row texts VERBATIM, and the continuation
carries the list's own three-space indent. That whitespace lands in the middle of
the token, which is exactly where the URL pattern stops. Flush-left wrapped URLs
(Claude Code's own `/login`) worked, which is why this survived.
The touch-selection helpers had the shallower version of the same bug: they walked
`isWrapped` only, so `Line` grabbed the single row on screen rather than the
logical line, and a long-press on a wrapped token selected only its visible half.
So the reconstruction now lives in ONE place, `terminalLogicalLine` in
constants.js, and both consumers use it — the link provider matching patterns over
its text and the selection helpers measuring words and lines with it. A link that
spans a wrap and a `Line` that stops at the screen edge were the same bug twice.
The helper drops the leading whitespace of a HARD continuation (the program's
indent) and keeps that of a SOFT one (the emulator inserts nothing, so it is real
content), records the dropped width per segment so the offset↔cell mapping stays
exact in both directions, trims only the final row so earlier offsets stay aligned
to cells, and keeps the 12-row bound that stops a screenful of full-width output
from being re-scanned on every hover.
⚠️ Selection spans are computed in CELLS, not text offsets: an xterm selection is
one contiguous run, so a token spanning a hard wrap also covers the indent cells
between its halves. A run that skipped them cannot be expressed, and would not
match what is highlighted.
Tests: `test/terminal-logical-line.test.ts` (8 cases: the indent drop, resolving
from either row, both mapping directions, soft continuations kept verbatim, no
over-reach past a short row, the row bound, final-row trimming, a missing row) and
5 in `terminal-touch-tap.test.ts` (the whole URL from either row, a token selected
across the wrap, `Line` spanning both rows, no reach into the next line). Removing
either half of the fix reds 5 and 8 of them respectively.
