The macOS executable patcher dropped PeImport::Weak, so every bind was
written without flags and dyld refused to load a binary whose weak
import no module exports. Carry the flag into MacOsBind and set
BIND_SYMBOL_FLAGS_WEAK_IMPORT for those binds, as Linux and Windows
already bind a missing weak import to 0.

The rebase onto main deleted docs/dev/TechnicalDebt.md, which is now the
index that points into docs/dev/debt/. Restore it from main and add the
missing final newline to docs/dev/debt/libSceNgs2.native.md.
Titles that link the character conversion library under its module name
need libSceCesCs-module.prx, which nothing built: Void Terrarium
(PPSA03061, #5055) and Call of Duty: Black Ops (PPSA34501, #5389) were
run with a copy of libSceCesCs.prx under that name. Both libraries are
now built from the same source by add_sce_ces_library, as libScePsml and
libSceFont-module are, and guest_ces_module runs the CesCs test against
the module-named library.

Resolve a host name to its first IPv6 address through the host resolver
(getaddrinfo with AF_INET6) and write the 16-byte address. The lookup
shares the IPv4 path's resolver bookkeeping (abort preservation, error
state); a name without an IPv6 address fails with RESOLVER_ENODNS like a
failed lookup. Nonzero flags throw.
Metal Gear Solid 4 Master Collection (PPSA18194) imports it and failed to
load without it (unresolved zl35YNs9jnI from libSceNet.prx).

Aps5FiberMain kept the fiber's entry address in rbp when it called the
entry, so the guest entry saved that code address as the caller's frame.
A guest walking frame pointers from inside a fiber read machine code as
a frame record and faulted. libSceFiber is now built with frame
pointers: Aps5FiberMain sets up a frame whose saved rbp is the zero of
the initial fiber frame, and the chain ends there.
PS5MC (PPSA99420, Kodi 22) imports chflags (ixrw0h2tWuI) from
libkernel.prx, one reference. Predicted stop once the imports ahead of
it (pthread_getthreadid_np, sendfile, wcstok, pause, setrlimit and the
termios calls) are covered (not a run):
FAIL: unresolved ELF import ixrw0h2tWuI from libkernel.prx
The NID is computed with tools/nid_names.py and matches aerolib.
Follows FreeBSD 11.4 (8c639945a44588f6cfdddfb057bb5aad88735da0)
sys/kern/vfs_syscalls.c kern_chflagsat and setfflags, and
sys/ufs/ufs/ufs_vnops.c ufs_setattr, for a root caller: the lookup
through the guest resolver gives EFAULT, ENOENT and ENOTDIR (also for a
file reached through a trailing slash or used as a directory), a bit
outside the 17 UFS flags of sys/sys/stat.h (VNOVAL included) gives
EOPNOTSUPP, and SF_SNAPSHOT gives EPERM, since the snapshot flag cannot
be toggled. No host keeps BSD file flags and stat reports st_flags 0,
so flags 0 succeed without touching the file and any other flag throws
with the flags named. UF_READONLY and the other Windows-attribute flags
are not mapped to FILE_ATTRIBUTE_READONLY and its siblings: UFS stores
them without enforcing them, and on Windows the read-only attribute is
already the owner write bit of chmod.

(cherry picked from commit 16e5b7ccd04e6467a5a282b6cfc9271304f42244)
Windows 10 1903 deletes a file with open handles by moving it into
$Extend\$Deleted until the last handle closes, so the next snapshot of a
watched file that a title (or the test) deleted saw a new path, tried to
watch that directory's changes, got ERROR_ACCESS_DENIED and threw from
the watch thread, which aborts the process; the path change was also
reported as NOTE_RENAME next to NOTE_DELETE. A snapshot with a pending
delete or no links now reports NOTE_DELETE alone and drops the parent
directory watch instead of replacing it, as the file has no directory
to be renamed or removed from any more.
Expand AGENT_FILES in tools/check_conventions.py to include instruction and configuration files for modern AI coding assistants (.windsurfrules, windsurf.md, chatgpt.md, .chatgptrules, .aider.conf.yml). Add test coverage in tools/tests/test_check_conventions_agent_files.py.
A draw with PA_SC_AA_CONFIG.MSAA_NUM_SAMPLES > 0 whose context never
wrote PA_SC_AA_SAMPLE_LOCS_PIXEL_* (context 0x2fe-0x30d) was rejected
with "missing register in context bank at DWORD 0x2fe", because the
registers were absent from the initial context (PPSA07411 stops on it
after two frames). The MSAA_ENABLE single-sample path read them the
same way.
The sixteen registers now start at 0, both initially and after
CLEAR_STATE. That is the value in libSceAgc's own register defaults
(sceAgcGetRegisterDefaults2, every public table that holds context
registers, the tables the initial context already follows for
PA_SU_VTX_CNTL and PA_SC_CONSERVATIVE_RASTERIZATION_CNTL), in amdgpu's
GFX10 clear-state table (clearstate_gfx10.h, gfx10_SECT_CONTEXT_def_8,
loaded by gfx_v10_0_cp_gfx_start before CLEAR_STATE) and the GC 10.3
register reset value (gc_10_3_0_default.h). RADV, radeonsi and PAL
always write the locations themselves and do not settle the unwritten
value.
0 puts every sample at the pixel center. That is not the standard
pattern for any sample count, so such a draw decodes as custom
locations at the center, as a single-sample scan into a multisampled
target already does.

The signature is inferred from PPSA12361: a 16-bit keycode, a second
argument the title passes as 0, the type from
sceConvertKeycodeGetImeKeyboardType and a UTF-16 output. The keycode is a
USB HID keyboard usage and the unshifted US character is returned; a
keycode without a character returns 0. A second argument or keyboard type
other than 0 throws.

git diff prints a file whose type changes (a file replaced by a link or
a submodule) as a deletion and a creation, two diff --git headers for
one --name-status entry, so the checker ran out of paths and stopped
with StopIteration instead of checking the pull request.

The fixture module was one RWX PT_LOAD, so its GOT slot sat in an
executable segment. On macOS 27, dyld refuses to bind a pointer there
("BIND_OPCODE_DO_BIND pointer bind is in executable segment '__ELF0'"),
and the x86-64 macOS branch of the test failed before reaching DT_INIT.
Split the module into an RX code segment and an RW data segment, as
real modules are laid out.

An existing directory, or a path ending in a separator, was only
rejected when the executable was written, after the converted modules
had already been written to app0/ beside or inside it.

FreeBSD sysctl_root rejects a write to a read-only node with EPERM before the node handler checks the MIB length, so a write with a short or long kern.proc.pathname MIB fails with EPERM. sysctlbyname for kern.proc.pathname now goes through sysctl with its 3-component MIB so it follows the same order.
