- Around line 61-67: Update the local run closure in Init to invoke
provider.execRemoteScript with Stdin unset, while preserving the existing Stdout
and Stderr streams, so initialization probes do not consume caller input. If
Init has no other need for it, also remove the unnecessary os.Stdin passed by
its caller.

context cancellation instead of the killed SSH process error. When runExternal
returns an error, check ctx.Err() first and wrap that cancellation error;
otherwise preserve wrapping of the process error. Update
TestExternalCancellation to assert errors.Is(err, context.Canceled), matching

- Around line 158-159: Update the review-gate status in the documented
verification section to state that PR #152 is published, current-head CI and
Greptile review have passed, and the exact-head CodeRabbit report remains
pending; remove the outdated claim that these gates await draft PR publication
while preserving earlier qualification results as historical.
Review comments at @pkg/ssh/remote_command.go:
- Around line 154-168: Update SSHProvider.execBuiltin to use a named return
error and add a deferred finalizer that, on any setup or session failure, joins
ctx.Err() with the existing error when cancellation is active and not already
included. This must cover builtinConfig, dialing, handshake, and runSession
return paths while preserving existing error details and runSession behavior.

Fixes the SSH-provider portion of devsy-org/devsy#1621. Both transports use one login-shell-safe
/bin/sh -clauncher carrying the exact original multiline script as one argument. Bash, Zsh and Fish receive identical command bytes; stdin remains available for injection and the live tunnel. Companion core draft: devsy-org/devsy#1627.Both transports preserve stdout bytes, stream stderr separately, retain context/process/source errors, and join stdin copying on completion or cancellation. Initialization uses the same executor, quotes paths, rejects unexpected stdout and leaves caller stdin untouched. Removes the obsolete Fish/SCP fallback.
At the user's request, this PR contains no verification document and no direct
cancelreaderdependency or imports. Its original indirect requirement is unchanged from main through the pinned core E2E framework and Bubble Tea; no dependency versions changed. Owned adapters preserve caller-owned files: Unix uses a poll wakeup pipe without changing descriptor flags, Windows redirected pipes retain owned duplicate handles, and console reads use owned handles and synchronized cancellation. The core module stays v1.23.2; E2E CLI downloads pin v1.24.0 with a local-binary override.Current signed head:
a14daf32a27e4efa253a913bc067f35261fd9a3c. Both checkout steps now disable credential persistence; no later step needs authenticated Git operations. Local race-enabled unit tests, applicable hooks, Windows-target lint/test compilation, and bounded independent reviews pass. Tests cover real-shell arguments, byte/exit/stderr transparency, setup-phase cancellation, late source errors, idle and unread input, once-only cleanup, caller-file flags/reuse, and pipe bytes/EOF.All seven current-head CI check runs and six workflows pass. Linux integration passed 18/18 specs with zero skips: released v1.24.0 core workspace startup (39.118 s), exact workspace SSH output (1.602 s), and cleanup (1.386 s), default Bash/Linux amd64. The native Windows job passes redirected-pipe and private-console cancellation tests. This is Windows runner qualification, not Desktop GUI acceptance. Earlier actual OpenSSH all-shell qualification is historical, not a new final-head runtime matrix or real-agent cold-transfer claim.
All five serial snapshot targets pass. GoReleaser reports 9m17s build time (about 9m19s for the workflow step), version
0.0.0-SNAPSHOT-1d27a39, from synthetic merge1d27a393078bafa2462df9ad80b6b6fd9ac08ac0. Its parents are base839369fc438c4616bace5ee15994ab42b0fd0773and PR heada14daf32a27e4efa253a913bc067f35261fd9a3c; merge and head share tree006d80ac3f9fc4acace710c1f4760d0867b9c37f. Artifact checksums are build metadata, not independently downloaded digest verification.All seven prior review findings are addressed and resolved. Fresh Greptile explicitly covers a14daf3 at 5/5 with no blocking issues. The configured GitHub CodeRabbit full review completed at 2026-10-21 04:56:55 UTC, explicitly setting sourceCommitId and coveredCommitId to a14daf3. It processed 23 files and reports no actionable comments or architecture-level concerns. The command acknowledgement confirms Full review finished. All seven prior threads remain resolved; no new inline findings were posted. Prior c9 reviews are historical. The separate local CodeRabbit CLI source-upload gate remains blocked by automatic approval review pending direct user authorization; GitHub review does not substitute for it. This PR remains draft and unmerged; no tag, release or customer reply was performed.
Summary by CodeRabbit
New Features
Bug Fixes
Documentation
Final audit confirms the current head remains draft and clean, all eight CI/Greptile check runs and six workflows pass, CodeRabbit status is Review completed, and GitHub verifies the Samuel K author/committer signature. CodeRabbit's docstring-coverage warning (5.32% vs 80%, including private helpers and tests) is accepted as no-action: important stream ownership/cancellation contracts are documented, and blanket comments would restate self-documenting names. The pinned core's former NewSSHClient and current identity configuration both use ConfigFromKeyBytes; read-only dependency inspection confirms the host-key callback is unchanged. All GitHub gates are complete, but the separate local CLI source-upload gate remains approval-blocked, so this draft is not declared fully ready. No merge, tag or release was performed.
