verification-architecture.md documents the existing two-stage design: the Cairn-inspired
search (brain + model calls on the VM) and the DAST proof (gVisor AX tasks in kube-ax),
the trust boundary (secrets VM-only, cluster tasks secret-free with restricted egress),
and the three verify lanes (ax=cluster default, vm=local Bubblewrap for $0 proofs,
docker=replay). Clarifies the proof is dynamic, not abstract interpretation: AI triage
stays the static backbone, proof earns the block by execution.
proof-arm-opencode/ is a follow-up brief: drive proof-authoring with OpenCode MCP, an
abliterated/GLM proof model (DeepSeek stays the search model), DSPy-optimized from
OpenObserve traces, to beat the safety-classifier refusals and nondeterministic wiring.
Flags the trust-domain decision that must come first (A: scoped key + egress inside the
cluster; B: brain on VM, only DAST in gVisor — recommended to start). Credentials live in
.env by name only (ABLITERATION_*, OPENOBSERVE_*); no secret value is in any tracked file.

Lockless old npm projects resolve era-appropriate deps (fixes glance filed->mime@4 crash);
npm ci untouched; git-failure falls back to plain install.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
A lockless npm project (e.g. glance, 2015) resolved an unpinned transitive range to the
latest major ([email protected] -> mime@4, which dropped .lookup()), so the built app crashed
serving files -- a build-reproducibility defect, not an app or agent fault. The executor
now, for the npm-install (no-lock) case only and only when .git is present, resolves
dependencies as of the checkout's HEAD commit date via `npm install --before <date>`,
giving era-appropriate, compatible versions. npm ci (lockfile present) is untouched, and
any git/date failure falls back to plain install. demo.py also recognizes
npm-shrinkwrap.json as a lock for the ci-vs-install choice.
Tests: executor + smoke 75 passed, demo 107 passed; ruff clean; mypy clean on executor.py.

Feed the milestone back into the spec and steering. HANDOFF: the open "first demonstrated"
question is RESOLVED -- xiaomusic (path, prefix-check-bypass) demonstrated on the vulnerable
side (3/3 affected, 0/3 safe) and the blind fixed-side search produced 0 false proofs; pair

Non-blocking advisory hint when the control shows the app didn't serve ${served_root},
so the agent self-corrects its served-directory wiring. Host-side; verdicts unchanged.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
When a path demo does not serve ${served_root}, the keystone control fails
(SideRecord.control_observed False) but the search only reported a generic
inconclusive, so the agent kept making the same wiring mistake. The pilot now
surfaces the affected side's control_observed in the verify result, and the
coordinator appends one advisory, deduplicated "served-root" hint (visible in the
board snapshot the agent reads) telling it to set the served-directory config to the
${served_root} placeholder. Advisory only: verdicts, _end, the oracle, the differential
and the demo validator are unchanged; the hint fires only when control_observed is False.
Tests: coordinator + pilot_run suites 78 passed; ruff clean; mypy unchanged (pre-existing
benchmarks errors only). Host-side change, no image rebuild.

Oracle broadening works in the agent: demo now targets the prefix-sibling vector. Still
inconclusive (0 false proofs, $0.29): the agent set the served-dir env var to its own
value, not ${served_root}, so the sibling canary was outside the served tree. Served-root
wiring is nondeterministic (a prior run wired it). Last-mile agent-reliability gap.

Plant a sibling canary so prefix-bypass path traversals (startswith without separator)
are demonstrable; parent canary + differential unchanged; glance still demonstrates.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
The path oracle only modelled classic parent traversal (a `canary` file in the parent of
${served_root}). A common real path-traversal class is the prefix-check bypass:
startswith(base) without a trailing separator, which the fix closes with base + os.sep;
it reaches a SIBLING whose path string-extends the served directory, not the parent.
PathOracle now also plants a sibling canary `public_leak` beside the served `public`
(same nonce, 0600), so a prefix-bypass demo leaks it on the vulnerable side and the fix
blocks it. ORACLE_GUIDE names the second target and tells the agent to pick the vector
its code shows. One shared nonce stays correct: a canary leaks only when the demo's own
request reaches it, and each demo targets one vector whose fix blocks it on the fixed side.
observe()/capture()/the differential/SideRecord are UNCHANGED. Local glance ceiling proof
still demonstrates (parent canary, 3/3 vuln, 0/3 fixed, control on both sides). Gate:
worker+control+verify suites 106 passed / 4 socket-skips; ruff clean; mypy clean on oracles.py.

Agent guidance: point the app's served directory at the ${served_root} placeholder via
arg/env/config so the planted observable is reachable. Prompt strings only; 37 worker tests pass.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Path searches authored and verified many demos but all came back with no differential:
the demo never pointed the app's served directory at ${served_root}, so the observable
(which lives relative to ${served_root}) was outside the served tree and unreachable. The
agent had set an app env var to a value of its own; the guide only showed the --dir form.
ORACLE_GUIDE now states the agent MUST set the app's served/root to the ${served_root}
placeholder via whichever mechanism the app exposes (command-line argument, environment
variable, or config written to start.files), not only --dir, and that serving elsewhere
makes the observable unreachable. Verify-time-only clarification, observable names, and all
prohibitions are kept. Prompt strings only.

Fair-share budget validated: the Python agent completed the full loop and verified 18
demos within $0.74 of $1.50 (0 verify tasks before). Still inconclusive, 0 false proofs.
Root cause of no-differential: the authored demo never references ${served_root}; the
agent pointed the app's served dir at its own value, so the observable was outside the
served tree. Next: guidance to wire the served dir to ${served_root} for the path oracle.

Each pilot search gets a fair share of --ceiling-usd with settled rollover, so one
expensive search can no longer starve the others; total stays within the ceiling.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
--ceiling-usd was one shared SpendBudget passed to every search, so an expensive
search drained the pool and starved later ones: in the last 2-pair/$2 run the first
search spent $1.60 and the second hit the ceiling at $0.34 after finishing its analysis.
The driver now allocates a dynamic fair share per search (remaining_ceiling /
searches_not_yet_started), rolls unused settled budget forward, caps each search at its
share, and keeps total settled <= ceiling. A search now gets room to author and verify
after it finds the path.

Agent guidance so path searches stop trying to confirm the oracle observable during
exploration (where it is absent) and instead author a demo for the differential verifier.
Prompt strings only; validators untouched; 37 worker tests pass.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
The parity fix named each oracle's observable, but path searches then spent their
whole budget without authoring a demo: the agent tried to confirm reachability during
exploration, where the oracle fixture does not exist (it is injected only in the
verifier's sandbox at verify time), concluded "unreachable", and never committed a demo.
ORACLE_GUIDE now states the fixture/observable is injected at VERIFY time only and is
absent during exploration; its explore-time absence never means unreachable or justifies
ending the search. The agent confirms the mechanism (sink reachability, access to data the
app should not expose) from app code and its own sandbox test data, targets the observable's
known verify-time location in the demo, and relies on differential verification as the only
proof. All prior prohibitions (no out-of-band/off-disk access, no input capture, no revision
sniffing) and the parity observable names are kept. Adjacent wording shortened to fit.

3 path searches (php/ts/py), vulnerable side, cluster verify lane, $2.95 of $3.
Payload-free aggregate; raw boards/demos stay gitignored. Finding: the parity fix
produced directed, target-aware search (the agent reasons about reaching the named
observable and inspects the app's serving guard), but no demonstration landed -- all
three spent their per-pair allowance before a differential, and two wrote zero verify
demos (budget consumed in reason/explore). Next levers: allowance/budget split toward
demo-writing, entrypoint discovery for php, and the explore-vs-verify path layout the
py agent flagged.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
The path family's agent guidance named no target, while command (${marker_dir}/marker)
and ssrf (${callback_url}) disclose theirs, so path searches could not author a demo
that surfaces the observable through the app. ORACLE_GUIDE now names it (canary in the
parent of ${served_root}, matching PathOracle.prepare). The reason/explore constraints
are refined to forbid only out-of-band access (direct disk reads, non-app channels),
input capture, and revision sniffing, while allowing the app to disclose it through the
vulnerability under test. Prompt strings only; the demo validator and its _PRIVATE guard
are untouched, so direct references to verifier paths remain blocked.

Honest serve signal for the HTTP verifier: SideRecord.control_observed records
whether a benign verifier-planted in-root marker came back through the app's
interface, as its own guarded app start that never changes the verdict. A
2xx-based block was rejected (any HTTP status counts as alive). Gate green;
ceiling re-proof on glance still demonstrated with control_observed on both
sides. The search task image needs a rebuild before the next cluster pilot.
Co-Authored-By: Claude Fable 5.1 <[email protected]>
The HTTP verifier could not distinguish a mis-wired or non-serving app from a
genuine no-effect: both yielded `inconclusive`. This adds a positive control for
the path oracle.
- PathOracle plants a benign in-root marker file (random token from os.urandom,
distinct from the secret canary) and exposes it via a new Oracle.control()
hook (default None; only the path oracle implements it today).
- On the first run of an HTTP side, _side runs a benign GET for that marker as
its own fully-guarded app start. The marker returning proves the interface
serves the fixture; its absence — or any control failure — is recorded in the
new SideRecord.control_observed field but never changes the verdict, since a
valid app may answer only its own routes. A crash is still caught by the
existing could_not_run path.
A 2xx-based "nothing served" block was rejected: the verifier deliberately
treats any HTTP status as the app being alive (a 503-only app is a valid
observed side), so status-based blocking would false-fail valid apps. Soundly
converting a mis-wired-but-responding app into could_not_run requires a
demo-declared control, which is a separate follow-up.
Tests: new tests/test_search_control.py covers marker observed, absent marker
not blocking, control failure not blocking a working attack, and crash still
could_not_run. Full search-verify/probe/worker suites pass; ruff clean; mypy
unchanged (only the pre-existing file_bindings lambda note).

Demos may reference ${served_root}, ${database_path}, ${marker_dir} or
${callback_url}; the verifier substitutes them per side, so apps that take a
