JVM startup, not analysis, is what a push scan spends its time on: each disposable
script invocation costs 13 to 23 seconds while the work takes under a second.
The session owns one Joern server per transaction on loopback with an OS-chosen
port and no published port. Three properties are load-bearing, and the probe that
settled the design demonstrated why each is needed.
An HTTP status is not an answer. The server returns success even for a compile
error, with the diagnostic in its body, so every request redirects the evaluated
code's console output into a fresh private file behind a nonce, and the nonce is
verified before the answer is accepted. The engine's body is retained for exactly
the case where the receipt is missing, without which that failure explains nothing.
A poisoned session answers nothing afterwards, and cancellation kills the process
group rather than the launcher, which this project has already run a machine out of
memory by neglecting.
What the probe established about the engine, after three iterations that each
failed loudly: runScript is absent from the server REPL; a shipped @main script
cannot be nested in a block expression, so definitions go to the top level
unwrapped; and the REPL shadows Console with io.joern.console.Console, which has no
withOut, so capture must qualify scala.Console. With that fixed, both mechanisms
answer identically to the disposable invocation, 0.8 s against 9.8 s.
The backend routes batch and single queries through the session only when
session_transport is enabled, which it is not by default. Any failure falls back to
the disposable invocation rather than reporting a zero, and each script is defined
under its own name because every script declares exec.
Equivalence for taint, dominance and configuration is task 11.2 and gates any
measured run. 1,391 tests passed, nine skipped. Rollout stays NO-GO.

The M1b exit run established the comparison but could not show a developer-readable
consequence or repair direction, because both belong to an evaluated capability
declaration and the installed registry is deliberately empty.
The experimental evaluation output now renders, for each change-attributed finding,
its family, exact location, witness, change attribution, provenance, engine method
and operation, together with a consequence and repair direction produced from a
supplied declaration through the same grounded-template path the admitted case
uses. No prose is invented: when no declaration matches, or a template is not
grounded in the operation and context, or the declaration does not cover the
operation symbol, the explanation is absent and the reason is stated.
Declarations reach this rendering only. The runner never passes them to admission,
so nothing in that file can enable a capability or emit an alert however it is
written, and a control asserts that even a declaration claiming PASS admits
nothing. The flag requires explicit base/head replay and the recorded-veto flag.
The evaluation instrument generates its own unreviewed declaration bound to the
run's analysis semantics, asserting that it is neither enabled nor PASS, so the
demonstration cannot drift into a qualified claim.
1,377 tests passed, nine skipped. Rollout stays NO-GO.

Add group 9 to the approved task plan as the bounded owner amendment release
milestone M1a requires, implement the task-local recorded-veto evaluation flag,
and run the three pinned NodeGoat revisions under it.
The flag re-runs the production comparison and admission over a lifted copy of
the same evidence and records each veto instead of applying it. Recognized
completeness vetoes are lifted and logged; failures never are, because silence
from a failure is not a quiet fixed twin. It is off by default, accepted only on
explicit base/head replay, refused in Git stdin mode, labels every payload it
produces, and admits no defect even when a lifted candidate otherwise would.
M1a outcome, inside its one-week box and with expectations frozen on disk first:
the three entailed <lambda>2 witnesses are present at contributions.js 32-34; the
fixed twin was genuinely analyzed and quiet, answering its target question with
zero rows and no deadline reason while the same findings appear as base-only; the
unchanged revision was analyzed and recorded unchanged. The kill criterion did
not trigger.
Five vetoes fired and were recorded. M1a also corrected the diagnosis: with all
five lifted the detection still stops at operation_correspondence_unresolved,
because a newly introduced operation sits on a changed line and has no base
anchor. The unchanged revision resolves its base location on the same lines and
classifies as unchanged, which isolates correspondence as the mechanism. That
fifth veto was not in the earlier four-veto diagnosis and is now M1b's central
repair.
Diagnosis only. No defect admitted, no capability enabled, no gate changed, no
latency claim; the 900-second development budget cannot measure the hook gate.
Rollout and task 8.3 remain NO-GO.
