Recover transparent geometry submit (+1,285 meaningful code, zero exact losses); reconcile COMMON ownership and Q10 85+EXT1 credit, actions/main data, and separately disclosed denominator corrections. Preserve canonical-only repairs and all held research. C09 is ordinary disclosed cleanup, not a claim of proven scaffolding intent. Clean rebuild, 1,663 tests, parks, audits, provider links and independent EXT1 check pass. Local reconciliation only.

|
* owner ruling (2026-09-20) because it is the admitted spelling of this
|
|
* square. Mechanism: written as d * d, VC7 computes the product ahead of the
|

* NUMBER_OF_ACTOR_THREAT_TYPES rather than NUMBER_OF_ACTOR_THREAT_TYPES-1,
|
|
* so its first iteration reads specific_threats[9] - one element past the
|
|
* end of the nine-element array, which is cumulative_threats[0].
|
|
* Evidence: January emits `mov eax,9` at +0xf5, then the six-byte alignment
|
|
* nop 8d 9b 00 00 00 00 (`lea ebx,[ebx]`, which touches neither EAX nor
|
|
* memory), and falls into the loop head at +0x100, `movsx edx,ax` followed by
|
|
* `cmp byte ptr [edx+esi+0x1ee],0`; the `dec eax` is at +0x10d, AFTER that
|
|
* load. In the same object actor_situation_update increments
|
|
* cumulative_threats for threat types 1..8 at esi+0x1f8..esi+0x1ff and
|
|
* area_friends at esi+0x200, which fixes cumulative_threats at esi+0x1f7 and
|
|
* so specific_threats at esi+0x1ee with exactly nine elements.
|
|
* Layout is asserted, not assumed: see
|
|
* actor_perception_specific_threats_size_assert and
|
|
* actor_perception_threat_arrays_adjacent_assert above, which fail to compile
|
|
* if the two arrays ever stop being adjacent or change length.
|
|
* Consequence: none observable. cumulative_threats[_actor_threat_none] is the
|
|
* one element of that array nothing ever writes - every write in the tree
|
|
* uses _actor_threat_visible..._actor_threat_damaging_me, i.e. 1..8, and the
|
|
* single variable-index use is a read-only csprintf argument in the
|
|
* actor_debug_print_threat macro - so the stray byte is always zero, the
|
|
* early-out is never taken on the stray iteration, and the scan falls through
|
|
* to the intended starting index. */
