Automated drive work from cloud run 8abf7774-4992-48ce-9996-7b96b527c0ff.

The sandbox cannot open PRs (no remote, no GitHub token), so this was delivered
from a host that can. Verification and adversarial review ran in-run — see
ops/reviews/ in the diff. A human merges.

Closing: this run resurrected kernel/relayflowd/src/engine/hn_poller.rs, which PR #16 deliberately removed after review rejected an in-kernel HTTP adapter. The build step's sandbox was seeded from a stale orchestrator archive and the commit step's git add -A swept the file in; the run's own assessment was correct and targeted the gate-1 race instead. No race fix reached the diff, so there is nothing here worth keeping.

…r fired

It compared $base_ref...HEAD, but at that point the run's patch has only been
applied to the working tree — nothing is committed, HEAD is still the base, and
the diff is always empty. So the guard passed silently and PR #17 was opened
containing kernel/relayflowd/src/engine/hn_poller.rs, the exact file it was
written to block, on the third consecutive run to resurrect it.

A guard that runs before the state it inspects exists is not a guard. It now
reads the working tree via git status, which is where the applied patch
actually lives at that moment.

My previous guard asked git 'was this file deliberately deleted?' and the
answer was always no — kernel/relayflowd/src/engine/hn_poller.rs was never on
main. It lived briefly on PR #16's branch and was removed inside that same PR
after review, so the squash merge left a history where it never existed. The
guard could not fire, and PR #17 shipped with the exact file it was written to
block. An earlier version of it could not fire either, because it compared
against HEAD before anything was committed.

Two failed guards on the same rule, both because I inferred the decision from
history instead of writing it down. An architectural decision that exists only
in a review comment is invisible to tooling.

ops/FORBIDDEN_PATHS now states it, and delivery checks every changed path
against it. DELIVER_ALLOW_FORBIDDEN=1 overrides one run; changing the rule
means editing the list in a commit that explains why.

P1 Badge Keep provider polling out of the kernel

When HnPoller::poll_once is called, relayflowd now performs Hacker News–specific network I/O by spawning curl, coupling the durable kernel to both an external provider and a host-installed executable. The parent already exports sdk/src/hn-poller.ts, which submits these events through event.submit; remove this kernel module and keep polling on that SDK/protocol surface.

…ntly

Third failure of the same guard, and the same root cause each time: the check
depended on state that was not present when it ran.

- v1 compared $base_ref...HEAD before anything was committed, so the diff was
  always empty.
- v2 read ops/FORBIDDEN_PATHS from the working tree — but the script checks out
  $base_ref first, and a base older than the list means the file is absent, so
  [ -f ] was false and the guard skipped without a word.

Both passed PR #17 through carrying the exact file they existed to block.

The list now comes from `git show origin/main:ops/FORBIDDEN_PATHS`, which does
not depend on the checked-out base. And a missing or unreadable list is now
FATAL: no denylist means no protection, and silence is precisely how the first
two versions failed.
