Three failures with one shape: a payload past a fixed capacity was met with silence, with a wait that never ends, or with a prefix presented as a whole. **The workspace snapshot was silently dropped.** `workspace.changed` carries the tab/session list, and a snapshot past the producer frame capacity (12288 B on a Node <=21 remote) was dropped with only a relay stderr line, so the client kept a stale list forever. The relay now publishes per client and, for a client whose sink refused the frame, sends a compact `workspace.stale` marker on the control lane; the client re-reads through `workspace.get`, whose lane is budgeted in megabytes rather than in one producer frame. A new JSON-RPC notification rather than a new field on `workspace.changed`: `normalizeSnapshot(undefined, ns)` yields revision 0 and an empty session, so a Rule-1 field would make an old client replace its tab list with nothing — worse than the drop. An old client ignores the unknown method and is exactly where it is today. The marker retention/retry machinery is extracted from the `fs.changed` overflow path and shared by both. **The Windows upload hung, and the fix for it could truncate.** `#16432` was attributed to `[Console]::In.ReadToEnd()` materializing the base64 bundle. That is not what the reporter measured: he also measured `new IO.StreamReader([Console]::OpenStandardInput())` — an incremental reader — hanging at 1 MB. The limit is in the stdin the host hands PowerShell over a non-pty ssh exec, not in the string the script builds. - `uploadFileViaSystemSsh` — the user file-import path — was piping a whole file into one Windows stdin, unchunked and untimed. That is the path large files take; it now chunks into 32 KB writes and bounds each wait. - The Windows directory upload reuses that single-file path rather than repeating a weaker copy of chunk-read + write-buffer; the `ino`/`dev` TOCTOU verification comes with it. - A Windows write needing more than one exec lands on a `.orca-partial` staging path and is published by rename, so a failed chunk cannot leave a truncated artifact under the real name. `exclusive` is enforced once at the rename, not on the first chunk, where a retry met its own leftovers. - The mkdir batch reads stdin through the stream reader the reporter measured surviving 50 KB, not `[Console]::In`, which he measured wedging at that size. - `waitForChannelClose` takes an optional bound. A wedged PowerShell stays alive at idle CPU and never closes, so without one the promise is simply never settled and the caller waits forever with no error to show. **Quick Open showed a prefix as the whole workspace.** The mechanism "a full page means there is more" only works if the caller named the cap, and the failing UI named none — it hardcoded `truncated: false`. Quick Open now names `QUICK_OPEN_LISTING_MAX_RESULTS` on both the Electron IPC hop and the runtime-RPC hop (the field #17954 added to `files.listAll`), and reads a full page as truncation. The local hop honours the cap too, which it previously ignored. Rebase note on `fs.listFiles`: an earlier revision of this work also clamped the host unconditionally, and #17934 escalated an uncapped request to an explicit error. #17954 has since landed and made an oversized reply streamable, which removes the premise — the host no longer has to choose between a prefix and a refusal, so it returns the whole listing when no limit is named and only clamps a limit it was given. Keeping either would have regressed #17954 and hard-failed three in-tree callers that deliberately pass no options (`runtime-file-commands-search-runtime-files.ts:81`, `filesystem-read-handlers.ts:125`, `runtime-file-commands-constructor.ts:41`).
