 ## 20. Prompts, program status and notifications
 
 - [x] T34 OSC 133 from the shell integration, which the owner asked for with everything below: zsh, bash, fish and PowerShell mark each prompt's start (A) and end (B), a command's start (C), and its end with the exit status (D); the tap reads any program's OSC 133; each session keeps its last command's status.
-- [ ] T35 Jump to prompt: a prompt's first row is marked once the prompt is drawn; Cmd-Up and Cmd-Down, and Cmd-Shift-Up and Cmd-Shift-Down, on macOS, Ctrl-Shift-Up and Ctrl-Shift-Down elsewhere, scroll to the prompt before or after the view's top, as in Ghostty.

 - [ ] T36 OSC 7501 program status, revision 0.4: reports checked as the spec checks them; records per terminal, by id, with clear and a cap of 256; a new prompt drops working, blocked and idle records, a full reset all; the support query answered with the states and kinds.
 - [ ] T37 OSC 9;4 progress as the root record until an OSC 7501 report; OSC 9, 777 and 99 notifications read, OSC 99's chunks, base64, ids, occasions, actions, close and query included; ConEmu's other OSC 9 commands are no notifications.
 - [ ] T38 Inside herdr, herdr's agent states from its snapshot are the session's records.

 - Round 1, c53b540: FAIL. PowerShell called a cmdlet's failure under `-ErrorAction Ignore` a success and read 1 for a native exit under `$PSNativeCommandUseErrorActionPreference`; bash 3.2 sent no C or D for a line that is only a subshell, and none at all while the user held a DEBUG trap; zsh left the first prompt unmarked under a theme that sets PS1 in its own hook. Testing before the review had found PowerShell's prompt broken under strict mode. Fixed in 0a22200: PowerShell reads a native code by the new object each run stores; bash 3.2 runs the user's trap after its own and keeps `$_`, which its trap had overwritten, and a lone subshell's D comes from the command number; zsh wraps the first prompt again through sched, which would reset `$pipestatus` on later prompts.
 - Round 2, 0a22200: FAIL. Under `extdebug` the bash 3.2 trap's status skipped the next command; a lone subshell still sent no C on bash 3.2; PowerShell gave a cmdlet's failure the code of a program run earlier on the line. A probe then found the trap running for key bindings as for typed commands, with nothing in it to tell them apart. Fixed in d4bc6e6: bash 3.2 drops its DEBUG trap and sends no C, its D from the command number; PowerShell reads the line's syntax tree, since a hook on every command lookup slowed a loop by half; each check waits for the prompt before its line, so a repeated status is the line's own.
 - Round 3, d4bc6e6: FAIL. The reviewer accepted bash 3.2 without C. PowerShell read 1 for a call through a variable, and bash without `promptvars` marked no command and said nothing. Fixed in 2c25116, after the last round, each with a check that fails on d4bc6e6: a line keeps a program's code unless it surely ends in PowerShell, and bash without `promptvars`, zsh without `prompt_percent` and PowerShell without PSReadLine say at start what they cannot mark. CI runs 1071 on c53b540, 1074 on 0a22200, 1076 on d4bc6e6 and 1077 on 2c25116 passed on macOS, Ubuntu and Windows; the Linux suite ran fish 4.0 and bash 5.2, CI's Ubuntu fish 3.7.

+- Round 1, 15e83f5: FAIL. A prompt that opens a link of its own lost its mark after that link, and a mark inside a link left open took over the program's target; a blank row inside a prompt split it in two; the rewrite made `133;AB`, which the session refuses, a prompt. Fixed in 310c219: an OSC that may be a mark is held until it ends and read as the session reads it, and each prompt's link carries the prompt's number.
+- Round 2, 310c219: FAIL. A prompt all inside a program's link carried no number, nor a first row that was; an ESC followed by 1 MiB of controls held them all, and the tap stopped reading. Fixed in e2bb615: a program's link inside a prompt keeps its target and carries the prompt's number in its id, a prompt inside a link left open opens it again with the number, and controls inside an escape go on before the ESC.
+- Round 3, e2bb615: FAIL. A target over 256 bytes went unnumbered, and the end of such a prompt left output numbered; controls after an OSC's closing ESC went on before it, so the parser, still inside the OSC, dropped a line break. Fixed in 11ec0ef, after the last round, each with a check that fails on e2bb615: targets are kept whole as the scanner keeps them, and the tap reads about 2 KB at a time to hold the growth, as fast through a pty as larger reads; an ESC that ends an OSC the parser has goes on at once. The reviewer's 33 round 3 probes then ran against 11ec0ef: 32 passed, and the one left counts 200 reads, which carry 2 KB each now, not a stall, as its pty twin showed READY. CI runs 1080 on 15e83f5, 1082 on 310c219, 1083 on e2bb615 and 1085 on 11ec0ef passed on macOS, Ubuntu and Windows. The keys off macOS are bound, not run.
