Three independent blind spots in the test harness.
1. smoke-select read symbols only from changed lines of a --unified=0
diff. An edit to the arguments of a multi-line call names nothing:
#741 (d5bdfde9) changed only the arguments of
runtime.resolveIsoOverlayFitEnvelope({ on the line above, and the
selection answered "unproven" plus the visual minimum, although the
callee is registered in smoke-links for smoke_iso_flat_parity and
smoke_isometric_contract - the two smokes the #741 author ran by hand.
The selection diff now carries CALL_CONTEXT_LINES = 3 lines of
context; for each changed line parseDiff looks for the nearest
unclosed "(" above it within the hunk, walking through a literal
argument ({ or [ after "(", "," or "["), stopping at ";" on depth zero
or any other unclosed brace. A callee from the symbol table joins
symbols and the new callees field and is marked "(вызов)" in the
report. Context lines never give direct symbols. task-packet takes a
separate context diff for selectSmokes; change-risk keeps --unified=0.
Over the last 80 src commits of dev: 16 commits gain a callee, 2 move
from unproven to a proven link (#741, #7245f8e8ca7), +15 smokes in
total, at most 4 per commit, none lost.
2. The #732 dead-field check judged only scene-builder calls. The four
resolveIsoOverlayFitEnvelope({...}) literals in iso-scene-render tests
went straight into the test-build function, so stageSize: null (the
field #741 removed) stayed green. They now go through overlayFit typed
with OverlayFitFixture (keys of IsoOverlayFitEnvelopeInput); the check
judges overlayFit/resolveIsoOverlayFitEnvelope calls like the scene
builders, and its probe asserts that OverlayFitFixture rejects
stageSize, so the type resolved to the real input and not to any.
3. smoke_backdrop's mode() called the private _setMode and slept 220 ms.
It now enters a mode through __hpTest.setMode and waits for the end of
the transition by the same markers as section 6b (#715): one page
helper used by both. Oracles and the 59 check names are unchanged.
Witnesses: d5bdfde9 selects both iso smokes with no "unproven"; the same
fixture without context lines is unproven again; attribution disabled
reds both AC1 units. stageSize: null in an overlayFit call reds the first
#732 test; a direct resolveIsoOverlayFitEnvelope({...}) reds the third.
smoke_backdrop is green normally and with animation frames slowed to 60
and 150 ms; a stage animation that never ends fails with a named error.
Issue: #754
