The table form read the field with `raw_get`, on the reasoning that a field
reached only through a metatable is not that table's to replace. A widget
carries none of its own methods — they live on the shared class table its
metatable's `__index` names (`object.rs`'s `frame_meta_for`) — so
`hooksecurefunc(frame, "SetAlpha", cb)` found nothing there and armed nothing,
silently. Measured: **0 fires across 2 `SetAlpha` calls**, while the plain-table
and global forms fired correctly.
That is not a corner of the form, it is what the form is for. 29 files in grom's
corpus hook a widget method, and the one that shows: `Cinematic/Frames.lua:459`
hooks each pfUI frame's own `SetAlpha` so that Cinematic can **follow** pfUI's
out-of-combat fade rather than fight it ("their frames have SetAlpha followed
straight away by ours, taking what it set as the new base"). With the hook
unarmed the two wrote a different alpha to the same frame on alternating frames
— which is grom's "still flashing my unitframe when cinematic is on".
The reference reads `table[name]` plainly and assigns the wrapper back, which
*shadows* the class method for that one object and leaves its siblings alone.
This now does the same: read through `__index`, write raw onto the host, which
is the same thing a plain assignment would do since frame metatables carry no
`__newindex`. A test pins both halves — the chain fires on the hooked frame, and
a sibling of the same kind is untouched, with nothing written to the class table.
Corpus roster byte-identical (87 ok / 1 fail) with all 29 files' hooks armed.
