A pasted GitHub PR comment deep link (#discussion_r… / #issuecomment-…)
now lands as a typed review attachment instead of a bare url chip. The
card attaches optimistically and resolves through gh in the background —
author, file:line anchor, body, and the diff hunk — expanding at send
into an anchored fenced block, so "address this" carries exactly what
"this" is. When gh can't answer (offline, unauthenticated, foreign repo,
remote gateway) the card downgrades to the plain url ref and nothing is
lost.
A session row can say whether its work is open, merged or closed, and link
to it. The join is the session's own repo + branch, asked of GitHub in one
batched GraphQL request per repo (branch aliases, not a `gh pr list` page
that a busy repo crowds ours out of), through the remote-aware git facade so
a desktop on a remote gateway asks the backend's `gh`.
Two ways a session's branch can't answer, both covered:
- It ran on trunk. Fork PRs share our branch namespace, so asking about
`main` badges a stranger's PR onto it — trunk is never asked about, and
cross-repository PRs are dropped server-side either way.
- It worked in a worktree, so the branch it recorded at start isn't where
the PR came from. Creating a PR from the review pane binds the session to
the branch it actually used, and for sessions that predate that, the PR is
recovered from the transcript: `gh pr create` prints a bare PR url and
nothing else, so a tool result whose whole output is one is a claim rather
than a mention. Scanned read-only across profiles, once per session ever.
simple-git's custom-binary validation rejects paths containing spaces, so
the default Windows Git install (C:\Program Files\Git\cmd\git.exe) made
every Review pane git call throw and the pane silently showed 'No diffs'.
The binary is resolved inside the Electron main process from known install
locations or PATH — never renderer/user input — so for spaced paths we opt
into simple-git's supported unsafe.allowUnsafeCustomBinary escape hatch
rather than falling back to PATH (often absent in GUI-launched apps).
Simplified from PR #64713 by @unsupportedpastels; supersedes the 8.3
short-path approaches in #55337/#60156.
Fixes#54888
