Measured on the plugin, first run of the adaptive sizer. A 600-visit portion answered in 184 s and
the budget was correctly cut to 262. The next portion, 199 visits, answered in 73 s -- three seconds
of work above the 70 s fixed start -- and 3 s over 199 visits read as 0.015 s each, so the budget
grew thirteen-fold to 3,404 visits. The ceiling killed that portion. The harvest kept the 13
answers it had streamed, which is the mechanism working; the sizing was not.
Two rules. A sample with less than ten seconds of work above the fixed start is not extrapolated
from, because it carries no information about cost per visit. And a budget may double per portion,
never more: the sizing may still be wrong, but by at most one factor of two, which a kill undoes.
1,423 tests pass, nineteen skipped; the sizer control asserts both rules.

A hard per-invocation ceiling is all-or-nothing. A batch killed at 301 s lost every answer it had
already computed, and the retry paid a fresh JVM start per part to ask them all again: measured, 116
requests killed at 300 s, then eight restarts carrying the same everywhere-sinks in every part.
Three coordinated changes make portioning, not the cap, the thing that governs cost.
The taint query STREAMS. The census first, then one line per request as it is answered, flushed as
it goes, inside the unchanged fence. The other queries do not stream and need not; the driver
reads both forms, and a legacy single document parses exactly as before.
The driver HARVESTS a kill. The process group is terminated first -- a first cut read the pipe
before killing and a pipe whose writer is alive never reaches end-of-file; the suite own
hanging-engine control sat on that read for twenty-eight minutes -- then the pipe is drained and
every complete line becomes an answer, marked partial. The retry asks only the remainder.
Portion sizing ADAPTS. After each portion the observed seconds per sink visit, less the fixed
start, resizes the rest toward a 120 s target; a portion that did not answer halves the budget
rather than being fitted, because its true cost is unknown and above the ceiling. A portion cut
down to fit puts its remainder back at the front of the queue.
A census LINE carries nothing but the census. A first cut misread a legacy document that carried the
census beside its answers as a census line and dropped every answer it sat beside; a control caught
it. Task 7.8 in contributor-scan.
Verified: 1,423 host tests pass, nineteen skipped, including new controls for the assembler in both
forms and under a kill, for a retry that asks only the remainder, and for the sizer. Not yet
verified: the joern-gated streaming check and the plugin measurement, which wait for the transfer
replay to free the machine and are stated as open in the task.
