…rectory is refused by kal_fs_list_next The shape openkal-linux#34 measured was here too. Listings not yet read to the end are kept on a list under a slim lock with their directory's handle, the close ends them, a listing another context is reading is released by that context on its way out (clause 6.6), and the iterator is found among the open listings rather than read through.
…sk_start_sized asks A reservation, as the other two implementations give, so a program that asks for nothing has the same room on all three. The reservation exceeds the request by the pages this environment keeps for its guard, so the context is told at least what it asked for.
This environment alters what is typed only while it assembles lines, and has no switch of its own for the alteration; the position is reported as it stands and a request for it is neither refused nor composed.
The leak is counted in this environment's table of the process's handles; a closed directory and a mismatched one are refused, and a close racing a read ends it. A console allocated by the test is given the return key and Ctrl+J as key events, and what arrives under each mode is printed beside the position's read-back. A least stack size is room, and asking for nothing gives 8 MiB.
The call that maps a key to one is user32's, which a test linked as this package's are does not reach; a key event written by a program carries none.
…the position states: the return key is 0x0d, and Ctrl+J is not it
…es a byte, so a key that produces none is measured rather than waited for
… measured With line input off and virtual terminal input off, the console delivered the return key as 0x0d and consumed Ctrl+J without a byte, which alters what was typed; with virtual terminal input on it delivered 0x0d and 0x0a, the bytes the other two implementations deliver with the position set. The position is read from both flags and established by the second; with line input on it reads clear and a request leaves it so. A console that refuses virtual terminal input is written again without it.

Temporary draft for cross-platform verification. Not for merge.
One branch name,
tmp/three-reports, across openkal, openkal-linux, openkal-macos, openkal-windows, openkal-emscripten and openkal-musl, so that each CI builds the others at the same branch. The commits are checkpoints; the final change will be one PR per repository after the design (.agents/docs/2026-10-25-three-reports-optimisation-design.mdin openkal) is reviewed, and this draft will be closed.What it carries:
kal_task_start_sized(a least stack size),KAL_TERM_PASS_INPUT(whether input is altered), and what closing a directory does to its enumerations.
