T37: programs ask for notifications through OSC 9, 777 and 99, read as Ghostty and kitty read them, OSC 99's chunks gathered by id with base64, options, close, query and alive, and the workspace hears each; OSC 9;4's progress stands as the root record until a program reports through OSC 7501, and again after a full reset

 | Prompt marks, OSC 133, from the shell integration and any program; each session keeps its last command's status | T34 | `term::marks` tests: each letter and option as Ghostty reads them; `term::tap` and `term::pty` tests: marks split across reads reach the session in order; `term::shell` tests: zsh, bash, fish and PowerShell send C, D;1, A and B around a failing command, and the user's prompt still shows the failure, a zsh theme's that sets PS1 in its own hook too, whose first prompt is marked before any command, and `$pipestatus` stays; bash's lone subshell ends with D;7, `$_` stays, a command runs under `extdebug` after a failure, a key binding marks nothing, the user's DEBUG trap runs, bash 3.2 sends no C, and bash says at start why it marks nothing while `promptvars` is off; PowerShell reads 1 for a cmdlet's failure under `-ErrorAction Ignore` after a success, a native code twice, a native failure's code under `$PSNativeCommandUseErrorActionPreference`, on a line that mixes a program and a cmdlet the cmdlet's 1, and through a call by variable the program's code; on macOS fish 4.9 marks itself and bash 3.2 marks no C, in the Linux container fish 4.0 gets B and bash 5.2 marks C through PS0, CI's Ubuntu runs fish 3.7, which the script marks whole; by hand in a pty, PowerShell under strict mode, and a cmdlet's failure after a native one's reads 1 | Pass |
 | Jump to the prompt before or after the view's top, as Ghostty jumps | T35 | `term::prompts` tests: a mark becomes its prompt's numbered link, read as the session reads marks, whole when split across reads at every byte, and other sequences, `133;AB` among them, pass as they came; a prompt's cells carry its link through SGR 0 and a resize, its input none; a program's own link and the prompt's keep each other, a program's link inside a prompt carries the prompt's number, a prompt inside a link left open too, a target of 264 bytes in either order; controls after an OSC's closing ESC keep their line; a long escape of controls keeps the pty reading; a prompt over rows starts at its first, blank rows within it too; up and down land as Ghostty's `scrollPrompt`; `term::links`: a prompt's link is no target; `term::pty`: through the event loop the prompt's cell alone carries it; in the app on macOS, Cmd-Up once and twice put PROMPT-3 and PROMPT-2 at the top, and Cmd-Shift-Down and Cmd-Down came back to the screen's bottom; the review's fixtures of a prompt that starts with a link and of a prompt with a blank row jumped to PROMPT-3-FIRST, and its fixture of `133;AB` marks found no prompt; the second review's fixtures of a prompt all in a link and of a linked first row jumped to PROMPT-3-FIRST. The keys off macOS are bound, not run | Pass |
 | Program status, OSC 7501 revision 0.4: reports checked as the spec checks them, records per terminal, a new prompt and a full reset, the support query | T36 | `term::status` tests: the spec's examples read as it means them; a malformed pair is skipped, the last of a key wins, unknown keys pass; a sequence over any limit, with bad base64, UTF-8 or a control character, or without a known state drops whole, a clear too, and an earlier pair of a key counts though the last wins; the sequence's length counts the controls its body skips; kind and progress count only with their states; records replace whole, clear with those under them, and past 256 the one updated longest ago goes; a new prompt keeps done and error alone. `term::tap`: a full reset found between bodies, and through DEL and high bytes in its escape. `term::pty`: a report, a query and a full reset reach the session in order through the event loop. In the app on macOS, a program that sent the query and then DA1 read the answer with every state and kind, then DA1's | Pass |
+| Progress, OSC 9;4, as the root record until an OSC 7501 report; notifications, OSC 9, 777 and 99, read | T37 | `term::notify` tests: OSC 9 reads as Ghostty reads it, ConEmu's commands no notifications, 9;4's progress clamped; OSC 777's notify; OSC 99 gathers chunks by id and reads base64, options, close, query and alive, and drops what breaks its rules; its answers name the asker's id. `term::status`: 9;4 maps to the root record until a report, and again after a full reset. `term::pty`: OSC 9, 777, chunked 99 and 9;4 reach the session in order. In the app on macOS, a program read OSC 99's query and alive answers before DA1's, and four notifications reached the workspace's log | Pass |
 | Inside herdr, the folder of herdr's focused pane, read from its socket, on macOS, Linux and Windows | T29, T32 | `term::herdr` tests: the socket found as herdr 0.9 finds it, only the terminal client followed and a remote one refused, the snapshot read, a socket round trip, a process's path, arguments and variables; `the_foreground_is_the_program_s_own_group`; on X11 with herdr 0.9.5 run in the session: its start showed the focused pane's folder, a cd in the pane moved the panel, the focus moved to a pane in `/etc` and back moved it each time, and the client's end gave the panel back to bash's report, then `exec herdr` from that bash, with `HERDR_SOCKET_PATH` relative to its folder, was followed through the socket there; on macOS under `shot`, herdr 0.9.5 as the program and again by `exec` from `sh` with a relative socket, its pane's cd moved the panel; on Windows, `term::herdr` tests on the CI runner: the folder under `APPDATA` and `USERPROFILE`, the `herdr.exe` nearest under the shell, this test's name, arguments and variables read through the live process list and `sysinfo`, a round trip over a named pipe; no real herdr has run on Windows yet | Partial |
 | Colors, styles, five underlines, wide characters, combining marks | T06 | `term::frame`, `term::ink`, `term::paint` tests | Pass |
 | Box drawing, blocks and powerline shapes as geometry | T07 | `term::boxes` tests | Pass |
