Plan 2026-10-20 (ENGINE step 4), Task A1, for #189 -- Captain Bob,
2026-11-12: the physics blocks alpha.5; order A, 1, 2, then 7.
- exec.h/exec.c: v4_call_hook, es->on_call/on_call_ctx; called at `call`
once the return address is pushed, before P moves. NULL: as before.
- heat.h/heat.c: the per-call-target table (4096 slots, no capsule word
counted), its freeze mask and v4_heat_call_* go (ENGINE.md step 3: "The
per-call-target count goes"); the kernel will keep a word's accounts.
- tests: test_call_hook_sees_every_call, seen to fail first (no on_call);
test_heat's per-call tests go with the table.
- the plan records today's rulings (order; HEAT-OP: both, a full array).
Suite (logs/20261112-225951/v4-tests): test, test-32, sanitize, 0
failures; hosted-check, the three alike. amd64 boot: POST 538/538,
dict_hash 0x8c92508f748f99cf, unchanged -- nothing sets the hook yet.
