… lane guard PR #12935 moved the archive bundle identity from PRODUCT_BUNDLE_IDENTIFIER to CMUX_APP_BUNDLE_IDENTIFIER / CMUX_HOST_BUNDLE_IDENTIFIER and made the manual App Store export require an extension provisioning profile, but the workflow guard still asserted the old build setting and had no extension profile, so workflow-guard-tests (and everything gated on linux-preflight) fails on main. Read the bundle id from the new setting in the fake xcodebuild, provide the extension profile fixture, and keep the profile-only installer tests free of the distribution identity. Same fix as carried by #12978. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

"GHOSTTY_TERMINAL_DATA_PWD" OSC 7 Ghostty source
💡 Result:
<search_synthesis>
In the Ghostty terminal emulator's source code, GHOSTTY_TERMINAL_DATA_PWD is a constant used to retrieve the terminal's current working directory (PWD) [1][2][3]. This value is updated when the terminal receives specific escape sequences, including OSC 7 (which typically uses a file:// URI), as well as OSC 9 (ConEmu CurrentDir) and OSC 1337 (iTerm2 CurrentDir) [2][4][5]. The terminal stores the raw bytes emitted by the shell for these sequences without parsing them [2][4]. When an embedder needs to access this information—for example, within a callback function like GhosttyTerminalPwdChangedFn—it uses ghostty_terminal_get with the GHOSTTY_TERMINAL_DATA_PWD identifier [2][4][6]. The returned value is a borrowed string that remains valid until the next mutating terminal operation [4][7]. If no PWD has been set, or if the shell clears it (e.g., via an empty OSC 7 sequence), the function returns a zero-length string [2][4][5].

💡 Result:
<search_synthesis>
The identifier GHOSTTY_TERMINAL_DATA_PWD is a constant used in the Ghostty terminal emulator's library (libghostty-vt) to represent the terminal's current working directory (PWD) [1][2][3]. In the Ghostty C API, GHOSTTY_TERMINAL_DATA_PWD is defined as an enum value (specifically 13) used with the ghostty_terminal_get function to retrieve the current working directory [1][2][3]. This value is updated when the terminal receives specific escape sequences from the shell, such as OSC 7 (file:// URI), OSC 9 (ConEmu CurrentDir), or OSC 1337 (iTerm2 CurrentDir) [2][3]. The retrieved value is a borrowed string that remains valid until the next mutating terminal call [4][3]. The hexadecimal string "35ae29b7c2bcee7c721d515d0096a9bc3f3242bb" does not appear to be a standard identifier or configuration key associated with Ghostty; search results indicate that similar hexadecimal strings are commonly associated with cryptocurrency wallet addresses on various blockchain explorers [5][6][7][8][9].

Publish an explicit OSC 7 directory clear.
Ghostty stores the current OSC 7 value in GHOSTTY_TERMINAL_DATA_PWD. An empty OSC 7 clears that value, and Terminal::pwd() returns None. The local and hosted incremental output paths pass that result with complete == false, so this guard drops the clear and leaves pty.pwd unchanged. The public graph can therefore retain the previous directory. Ordinary output without a cwd report keeps Ghostty's existing PWD, and the equality check still suppresses repeated initial None values.
Remove this return:
Proposed fix
pub(super) fn record_directory(&self, value: Option<String>, complete: bool) {
- if value.is_none() && !complete { return; }
let mut previous = self.pwd.lock().unwrap();
if *previous != value {
*previous = value;
self.directory_pending.store(true, Ordering::Release);
}Add a parser-path regression that publishes a valid OSC 7 directory and then clears it with an empty OSC 7 report.

Hide unconfirmed Cloud directories.
recordCreatedTerminal creates a Cloud SurfaceResource with detail: cwd and immediately inserts it into the catalog. upsert preserves that value. Until the first accepted CloudVMState, cloudStateObservations[resource.machine] can be nil. The current guard then returns the raw resource, so snapshot.resources can expose the launch-time directory before Cloud state confirms it.
Clear detail for Cloud terminals unless the observation is .current:
Proposed fix
- guard resource.kind == .terminal,
- cloudStateObservations[resource.machine]?.freshness == .stale else { return resource }
+ guard resource.kind == .terminal,
+ resource.machine.cloudMachineID != nil,
+ cloudStateObservations[resource.machine]?.freshness != .current else { return resource }📝 Committable suggestion

The devbox prompt hook never emitted OSC 7, so the cmux-tui daemon had no directory to publish and the Cloud workspace row could not follow a remote cd (#12975). Cover the exact report shape the daemon accepts: a file URL on this host with the cwd percent-encoded, produced by builtins only, with the previous command's exit status preserved. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The cmux-tui daemon learns a terminal's directory only from OSC 7, but the devbox prompt hook never emitted one, so no remote cd could reach the Cloud workspace row even with the daemon and Mac projection fixed (#12975). The hook now reports file://<host><cwd> before every prompt with builtins only, percent-encoding the path the way the daemon's file-URL parser requires. Sourcing the file still only reads the machine name; the report belongs to the prompt hook so custom PS1 values keep working. The installer rewrites /etc/cmux/prompt.bash on the next attach, so existing machines pick this up without a new image; new bakes carry it directly.

Biome 2.5.0 noControlCharactersInRegex Unicode escape recommended rule official documentation
💡 Result:
<search_synthesis>
The Biome lint rule noControlCharactersInRegex is a recommended rule that is enabled by default [1][2]. It is designed to prevent the use of control characters (ASCII 0-31) and specific escape sequences that represent them within regular expression literals [1][3]. According to the official Biome documentation, this rule specifically disallows the following elements in regular expression patterns because they are considered likely typing errors [1][2]: - Hexadecimal character escapes from \x00 to \x1F [1][2] - Unicode character escapes from \u0000 to \u001F [1][2] - Unicode code point escapes from \u{0} to \u{1F} [1][2] - Unescaped raw characters from U+0000 to U+001F [1][2] The rule explicitly allows control escapes such as \t and \n [1][2]. Regarding your query about "Unicode escape recommended," the rule does not mandate or recommend Unicode escapes in general; rather, it identifies specific Unicode escape sequences (those mapping to control characters) as invalid [1][2]. Valid Unicode escapes that do not represent control characters (e.g., \u0020) are permitted [4][2]. There are no specific changes to this rule's core functionality in Biome 2.5.0 [5][6]. However, it is worth noting that in recent development (as of March 2025), support for dynamically built regular expressions was removed from this rule to simplify its implementation and improve consistency [7]. For general best practices regarding Unicode in regular expressions, Biome provides a separate rule called useUnicodeRegex, which encourages the use of the u or v flag to ensure proper handling of Unicode characters [8].

Suppress the intentional OSC 7 control characters.
The \u001b and \u0007 sequences are valid JavaScript escapes, but Biome's recommended lint/suspicious/noControlCharactersInRegex rule treats them as disallowed control-character escapes. Replacing them with \x1B and \x07 does not clear the rule.
Proposed fix
- `).replace(/\u001b\]7;[^\u0007]*\u0007/g, "")).toBe("1|__cmux_prompt_name|:|printf user-hook|");
+ `).replace(
+ // biome-ignore lint/suspicious/noControlCharactersInRegex: OSC 7 uses ESC and BEL delimiters.
+ /\u001b\]7;[^\u0007]*\u0007/g,
+ "",
+ )).toBe("1|__cmux_prompt_name|:|printf user-hook|");📝 Committable suggestion

…s reported cwd On a Cloud machine every terminal is hosted, and a tab or split created from the selected one always started in its launch directory instead of where the shell had since moved (#12975). Cover the daemon's one inheritance point: a hosted terminal that reported a cd on this host with OSC 7 seeds the next terminal's spawn directory, while a report naming another host still falls back to the authenticated launch directory.

…eir OSC 7 report Surface::local_cwd chose the strict host-validated OSC 7 converter for hosted terminals and then never applied it, so on a Cloud machine a tab or split created from the selected terminal always started in that terminal's launch directory. Apply the converter: a report naming this host (localhost or the machine's own hostname, with a safe path) becomes the spawn directory, the same rule the published directory already follows; a foreign or malformed report still falls back to the authenticated launch directory.

The incremental parser path dropped a directory clear, so a shell that stopped reporting its cwd left the previous directory in the public graph. Drive a real shell through OSC 7 then an empty OSC 7 and expect the snapshot cwd to be published and then removed. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
record_directory ignored a None pwd on the incremental parser paths, so a shell that cleared its directory report (an empty OSC 7) left the previous cwd in the public graph and on the Cloud workspace row. The VT keeps its pwd across ordinary output, so None there is a genuine change; treat it like any other report and let the equality check suppress repeats. The complete flag only existed for that guard. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

cdcould leave the left workspace row showing an old directory, while its Cloud icon exposed only a machine ID on hover. This change presents the machine's friendly name and stable ID beside remote directory metadata, and updates that metadata from the accepted Cloud graph without changing custom workspace titles.The trace found two breaks: cmux-tui's public terminal snapshot exported the launch cwd without publishing OSC cwd changes; the Mac projected directory changes only when a delta also changed workspace/tab names. Terminal cwd now commits through the existing ordered resource journal. Catalog transactions independently project directory and machine metadata to workspace snapshots, including background terminals, machine rename, projection changes, reconnect and restore. Missing/stale directories show a localized unavailable state, and local renderer reports cannot override the Cloud graph.
Validation in progress:
23a66c1ebf, followed by implementationd22b388cc9.The presentation adds machine text to the existing directory metadata space. Hover and accessibility retain the friendly name plus stable ID; narrow candidates retain the stable ID. A restored/offline cwd is withheld until remote confirmation rather than presented as current. The daemon journals only actual cwd changes, preserving the existing revision fence and avoiding a second unordered cwd channel.
No new socket method, relay allowlist entry, or ID parameter is introduced. The existing renderer/report path is narrowed for Cloud provenance. Cloud tree geometry, pinning, creation, workspace deletion and other command paths are unchanged.
Fixes #12975. Related: #12347, #12515, #12575/#12743.
