A script's code was cut at the character limit before its ST_Xstring escapes
were decoded, so a script whose escapes (`_x0009_`, `_x000D_`) made the file's
text longer than the limit lost its end without a warning, although its code
fits. The code is now decoded first and then cut one character past the limit,
so a script that is too long once decoded still fails the check and its cell
keeps only its value, as before. Decoding is linear and reads at most a bounded
number of encoded characters, enough for any code that fits.
A PY formula whose script the file doesn't hold (the Python part missing or
damaged, or the script over the code budget) keeps only its cached value, but
its array range stayed recorded, so the cached values over the rest of its
spill were dropped as a formula's spill would be, and nothing filled them
again. The range of such a cell is now forgotten when it is read: the anchor
and the cells of its spill keep their cached values as plain values, as the
file shows them, with no live spill. An ordinary formula's dynamic-array spill
is handled as before.
A Python part whose zip entry failed to read (a bad checksum or compressed
stream) made the whole workbook fail to open: the error was passed up, and the
failed read had also ended the package's read budget, so even a warning would
have left the sheets unread. The part is now read with
Package::read_optional_limited, which charges a failed read only that part's
allowance, and every error other than TooLarge is a warning. The Python cells
then keep only their cached values, as when the part is missing. Malformed XML
in the part was already a warning; the test covers it too.
When a file's cached Python spills were larger than the adoption budget, the
cells past it kept only their own value, but their spill ranges and spilled
values stayed on the sheet, which went on showing values no result held. The
spill of such a cell is now cleared, as for a dropped result; the warning is
unchanged.
A cell formatted Hidden on a protected sheet hid its formula but not its
Python code: display::formula_hidden only looked for a formula at the cell (a
Python cell was covered only while its result spilled), and the formula bar
had its own check for formulas alone. Both now treat Python code as they treat
a formula, so the formula bar shows nothing for a hidden Python cell, as it
does for a hidden formula. Editing the cell is refused as before, because it
is locked.
Replace matched a Python cell on its code and then rebuilt the cell from the
replaced text as if it had been typed, so the cell became a text cell holding
the edited code and the Python cell was lost. The replacement now edits the
code: the cell stays a Python cell with its return type, its result is dropped
(#BLOCKED!, as for any changed code) and a spill it had is cleared. Code that
would no longer fit in a PY formula is left unchanged and counted in a new
skipped field of the result.
The footprint dry run and the per-step guard of macro runs (new on main)
compared formulas and values only. A step that replaced a Python cell with
its own cached value, or with other code that also shows #BLOCKED!, was not
counted as a write over data, so the code could be lost without the
question. A step that only blocked a Python cell's spill, which leaves its
code as it was, was counted as one. Python code is now content as a formula
is: a change of code or return type is a write, and a change of the cached
value alone is a recalculation.
* Fix#2812: Intel Macs skip wgpu's indirect-call validation shaders
Metal's Intel compiler aborts on wgpu's indirect-validation compute shaders
("Compiler encountered an internal error"; MTLCompilerService crashes in
reportUnsupportedMaxWorkGroupSizeMetadataError), the device is lost inside
request_device and GridCraft exits before its window opens. GridCraft issues
no indirect draws or dispatches, so on Intel Macs the instance leaves
VALIDATION_INDIRECT_CALL out; WGPU_VALIDATION_INDIRECT_CALL=1 turns it back
on. Every other platform keeps wgpu's default. Same as WordCraft (#2652 there).

* Review: test that WGPU_VALIDATION_INDIRECT_CALL=1 still turns it on; qualify the doc line
The override is checked in a child test process with the variable set, since
tests can't set environment variables without unsafe code. The revision line
no longer says Intel Macs start: OpenCore Legacy Patcher Macs on macOS 15 can
still fail on the MSL version (#1116).
