Fusion Agent 017ebd5059 FN-201: park workspace review revisions for human resolution
Preserve multi-repository review findings and route unresolved REVISE outcomes to human review.

- Qualify workspace findings by repository for durable scope and remediation tracking.
- Preserve findings through graph outcomes and stabilize remediation signatures.
- Park multi-repository review revisions for human resolution with regression coverage.

Pure so the decision is testable without driving a whole graph run. A write-capable node on a
workspace task runs from the task DIRECTORY, a container of per-repository worktrees with no `.git`
of its own; with no declared boundary the session applies the single-repo assertion to that
container and refuses to start ("Refusing to start coding agent in incomplete worktree"), so the
gate fails before producing a verdict and the task requeues to todo. `workspace-task-dir` validates
the per-repository children instead. `undefined` preserves the existing implicit boundary for
single-repo tasks, for the legacy per-repo layout, and when the scope is unconfirmed (a
zero-repoRoots descriptor is itself refused, so guessing only trades one refusal for another).

a worktree and refuses to start: "Refusing to start coding agent in incomplete worktree". The

Malformed review output (no parseable verdict, even after the fallback-model retry in executeWorkflowStep) was treated as a NON-BLOCKING advisory rather than a hard gate failure. Operators asked that an unparseable reviewer response not block a task in review — a genuine REVISE (parsed verdict) still blocks, and the advisory_failure value keeps the malformed result visible on the Workflow tab.
FNXC:ReviewLeniency 2026-08-26-09:34:
A BLOCKING gate no longer approves on malformed output. Operator decision, reversing the line
above with the reason it was missing: "the only valid reason a task can be blocked is an LLM
problem (429, 503); everything else is fixed at the source, or the AI is made unable to return
anything other than what is expected — and if it does anyway, restart cleanly".
Restarting cleanly is ALREADY implemented, twice: `executeWorkflowStep` retries a malformed
primary on the fallback model, or self-retries once on the primary when no fallback is
configured. `malformed` therefore does not mean "one fumbled response" — it means the reviewer
failed to return a usable verdict across every attempt, which IS the LLM-class condition the
operator accepts as a legitimate stop.
What it must never mean is APPROVAL. Measured on a real card: a reviewer reported in prose that
the deliverables were absent, carried no verdict JSON, and the gate recorded success — unreviewed
work merged on a rejection nobody could see. The prose classifier cannot close this: that text
contained no rejection marker at all (no "revise", "reject", "must fix"), because it was a
factual statement of absence. Only the ABSENCE of a verdict is detectable, so absence must not
approve.
Advisory gates are untouched: `!blocking` still passes, keeping the original operator ask exactly
where it applies — a step that was never allowed to hold a card cannot start holding one.
