Michael GrundbergandClaude Opus 5 3edf9aae2f fix(terminal): replay a pane capture at the geometry it was taken at
A visible-frame capture repaints each row at an absolute position, counting up
to the pane's height. A terminal shorter than that clamps every address past its
own height onto its last line. The overflow rows then overwrite one another, and
the rows underneath are lost. Replaying a real 50-row capture into a 30-row
terminal rendered 28 lines of a 45-line command and drew the frame twice.

Nothing in the response said what height the frame was built for, so the client
could not detect this. A capture now reports the geometry it was really taken at
through `capturedGeometry` on `PaneCaptureOptions`, and the terminal response
carries it as `captureCols` and `captureRows`. When the captured pane is taller
than the terminal, or the size that produced the capture did not survive the
load, `selectSession` replays once at the size that stuck. `resizeRetry` caps
that at one attempt, so two competing fits cannot trade replays forever.

The retry re-arms the full-history flag only when the pass that ran had consumed
it. A tab switch takes the bounded tail, so its retry takes the tail too:
clearing the flag unconditionally would upgrade that switch into a fresh
scrollback capture the user never asked for, which the route's own comments put
at tens of megabytes.

What this repairs is a capture that won a race against the resize meant to
precede it. It does not repair a capture whose pane was too tall because
`Session.resize` declined the resize outright, which it does for a small
viewport while a desktop viewport's size claim is live. The retry re-sends the
same declined resize and captures the same pane, and `resizeRetry` then stops
it. Repairing that means changing who owns the pane size, which is a policy
question this does not touch. The reported geometry still helps there, because
the client can see the mismatch at all rather than being blind to it.

Follows #395, #396 and #397, which fixed the other ways the replayed frame and
the terminal could disagree.

Changesets

Hello and welcome! This folder has been automatically generated by @changesets/cli, a build tool that works with multi-package repos, or single-package repos to help you version and publish your code. You can find the full documentation for it in the repository.

What is a changeset?

A changeset is a piece of information about changes made in a branch or commit. It holds three bits of information:

  • What packages need to be released
  • What semver bump type each package should receive (major / minor / patch)
  • A summary of the changes

How do I create a changeset?

Run npx changeset or create a .md file in this directory with the following format:

---
"codeman": patch
---

Description of changes

The frontmatter specifies which package(s) to bump and the bump type. The body is the changelog entry.
