A clicked path that points OUTSIDE the case directory goes through the attachment
routes (the frontend's `_isExternalPreviewPath` sends every absolute path not under
`workingDir` to `POST /attachments`), and those had the same local-`fs` assumption
as file-raw: `realpathSync`/`fs.stat` on a path that only exists on the remote host,
so the file never opened — the case the #415 report was actually about.
- `registerExternalAttachment()` accepts `remote` and resolves through
`remoteProbePaths` (canonical path, size/mtime, kind, plus the workspace root for
the confinement check). Everything around it — blocklist, extension allowlist,
workspace confinement, registry/dedupe — is now shared by both branches, so the
remote path cannot drift from the local one.
- The by-id routes (`raw`, `preview`, `thumbnail`), the metadata poll and the
attachment history list resolve over ssh too. `raw` streams with the same
Range contract as file-raw; `preview` (office) and `thumbnail` answer 400 for a
remote record; an unreachable host answers 502, a vanished file 404.
- Which host a record is read from follows the SESSION, never the path string: the
same absolute path is a different file on each host, and a remote session never
falls back to a local file with that name.
- Codex generated artifacts keep force-workspace confinement for a remote case: the
well-known artifact directories are anchored at THIS host's home, so only a file
inside the remote workspace is trusted.
Still local-only by design: writes, office conversion, thumbnails, the file
tree/picker and tail-file.
- Pass the attachment request `source` through the server deps lambda and make
it a required param on SessionListenerDeps.registerAttachment + the wiring
event type (the 2-arg lambda silently dropped `source`, force-confining every
codex-generated artifact — the feature never worked outside the workspace);
new test/session-listener-wiring.test.ts asserts the pass-through
- Gate the Codex `Saved to: file://` scanner on mode === 'codex' via a
codexArtifacts option threaded from the session call site; magic links stay
mode-agnostic; tests assert claude/shell sessions never emit codex-generated
requests
- Decide the generated-artifact trust policy on the realpath-RESOLVED path
(unresolvable → force-confined) and anchor the ~/.codex marker dirs to
os.homedir() prefixes with startsWith instead of substring matching; symlink
escape + unanchored-marker regression tests added
- Run the Codex scanner on stripAnsi'd data so trailing SGR sequences don't
ride into the captured URL; styled 'Saved to:' test added
- Extend generateFirstPageThumbnail with jpg/jpeg/gif/webp passthrough and
per-extension content types (mirrors the png passthrough) so the PR's new
image formats render real thumbnails instead of 204 letter-tiles
