Seed INTENT and WP-0001: adversarial evidence facility Answers the Tenancy Posture question that has been unowned since the framework was drafted - who verifies a consumer's tenant boundary. Two repos were asked and both correctly declined as fleet-scope work. The work needed a home. Independence is the load-bearing property, not a nicety. rapp-postgres wrote fifteen probes against its own isolation model and found four real defects, which is good work and still the author checking their own homework. The probes worth having are the ones the author would not think to write, because the assumption that produced the defect produces the blind spot. That argues against NetKingdom owning this even though it owns the security canon: a facility verifying conformance to a framework must not report to the repo that owns the framework, or self-grading just moves up a level. Proposed owner is the-custodian, consistent with policy and risk. Needs confirmation. Two things stated because overclaiming is the failure this estate keeps catching in itself. "Automated" has a ceiling - the highest-impact cross-tenant findings need someone who understands what the data means, since a response can be well-formed, 200, fast, and contain another tenant's rows; so automate the reproducible and flag the irreducible for dated review. And a passing suite proves the attacks we thought of did not work, not that the boundary holds. The gap between those sentences is where breaches live. WP-0001 gates everything behind rules of engagement, because an automated facility probing systems without written scope is indistinguishable from the threat it models. No standing privilege, no BYPASSRLS, no superuser - an attacker would not have them and a probe holding them proves nothing. No exfiltration of real tenant data even as proof; a count and a schema shape are proof enough. And no saturation probing outside a declared window, because with a six-consumer connection ceiling that is an outage for every co-resident. T04 exists because a probe that has only ever passed is not evidence.

# WHITEHAT-WP-0001 — cross-tenant evidence
## Goal
Produce, on a schedule, the adversarial evidence artifacts that NetKingdom's
*Tenancy Posture* standard requires and no repo can honestly produce about
itself — starting with the one the framework calls its highest-severity gap.
Done means: a service claiming `E2` has been attacked as an adversary holding
its runtime credential, the attempt is recorded with a date and an attacker
model, and a failure routes to `risk-nexus` rather than to a log nobody reads.
## The forcing case
*Tenancy Posture* open question 3 has been unowned since the framework was
drafted. What it calls a tenant-boundary failure the security industry calls
**Broken Object Level Authorization** — OWASP API1, top of the API Security Top
10 since that list launched, and the most commonly exploited API vulnerability
in published assessments.
The estate has no coverage for it. `rapp-postgres` runs fifteen adversarial
probes and every one targets the *consumer* boundary — service versus service.
None targets the tenant boundary *inside* a consumer, which is where the
framework says the residual risk actually lives.
## Rules of engagement — T01, and nothing else starts first
An automated facility that probes systems without written scope is
indistinguishable from the threat it models. This is the gating task and it is
not paperwork.
NetKingdom owns this; and a targeting rule, because scope widened Operator decision: whitehat is a NetKingdom facility, framed offensively - offence is how you find out, and a control is believed until someone tries it. Our own estate is one target among those we choose, not the only one. I had argued for the-custodian on independence grounds. The counter-argument is better: offensive security is security work and belongs with the security repo. The residual tension is real and recorded rather than argued away - NetKingdom now owns both the Tenancy Posture framework and the facility that tests conformance to it, which is NetKingdom assessing NetKingdom. The mitigation is that findings leave for risk-nexus under separate ownership rather than being resolved in place. Proportionate, not perfect, and worth revisiting if conformance findings start getting quietly closed. The reframe changes what this repo must guard against, and that is the substantial part of this commit. A facility that can be pointed at infrastructure we do not own is the single thing that could turn this repo from an asset into a liability, so the targeting rule is structural rather than cultural. No target without recorded authorization from whoever is responsible for it. Own estate in build mode has standing authorization; production needs its own, because the blast radius differs and so does the decision; anything we do not own needs written per-engagement authorization recorded here before a packet is sent. Three non-authorizations written down because each is a way teams talk themselves into it: a commercial relationship with the target, the target being publicly reachable, and believing the owner would obviously be fine with it. Unauthorized probing is criminal in most jurisdictions regardless of intent, and a white-hat facility that gets this wrong is an attacker with better paperwork. Two consequences. The authorization record is part of the finding - a report that cannot name what it ran under is not a finding, it is an incident.

- **Target authorization**, the control that matters most now the facility is
scoped to any surface we choose rather than only our own. No target without a
recorded authorization from its responsible party. Our estate in build mode
has standing authorization only as a prerequisite: every live run still
needs the dated engagement record and target-owner acknowledgement defined in
the rules of engagement. Production needs its own authorization; anything we
do not own needs written per-engagement authorization recorded here before a
packet is sent. A commercial relationship, public reachability, and "they
would obviously be fine with it" are each explicitly not authorization.
NetKingdom owns this; and a targeting rule, because scope widened Operator decision: whitehat is a NetKingdom facility, framed offensively - offence is how you find out, and a control is believed until someone tries it.

- **Scope.** Which systems, which namespaces, which credentials — and a hard
stop at the engagement boundary. A probe that discovers an adjacent system
reports what it saw and does not follow it.

- **Prohibited actions**, stated as hard rules rather than intentions:
no destructive operations against data the estate did not create for the
test; no exfiltration of real tenant data even as proof of a finding —
a count and a schema shape are proof enough; no denial-of-service against a
shared substrate outside a declared window, because the connection ceiling
means a saturation probe is an outage for every co-resident.
- **Credentials.** The facility holds leased credentials like any workload,
through the sanctioned OpenBao lane. It gets no standing privilege, and
notably **no `BYPASSRLS` and no superuser** — an attacker would not have them
and a probe holding them proves nothing.
- **Attribution.** Every probe connection is identifiable as a probe in
`pg_stat_activity` and in logs, so an operator investigating an anomaly can
tell us from a real adversary in seconds.
- **Abort.** How a run is stopped, by whom, and what state it leaves behind.
**Output:** `docs/rules-of-engagement.md`, reviewed by the operator personally.
This is exactly the class of thing `risk-nexus`'s escalation duty exists for.
## Tasks
### T01 — Rules of engagement
As above. Gates everything.

```
Drafted in `docs/rules-of-engagement.md` on 2026-08-18 with authorization
classes, per-run records, initial target envelope, hard prohibitions,
credential/attribution rules, rate defaults, abort/cleanup and evidence
schema. The operator accepted v0.1 on 2026-08-21 with the scope recorded in
what is now §11. v0.2 (2026-08-22) adds §10, the governed test plane, as a
stricter admission control. It does not expand authorization. The acceptance
approves the operating rules and offline fixture work; it does not
pre-authorize any live target.

What the adversary is assumed to hold, so a probe is judged against a threat
rather than against taste. Drawn from *Tenancy Posture* §4.3, which already
distinguishes them:
| Axis | Adversary holds | Probe answers |
|---|---|---|
| E1/E2 | A legitimate runtime credential and the ability to make ordinary requests as tenant A | Can it reach tenant B's rows? |
| E3 | The above, plus SQL execution on the connection | Can it re-`SET` the tenant GUC and read across? |
| E4 | A leaked per-tenant credential | Can it address another tenant's substrate at all? |
| P1/P2 | A co-resident consumer behaving badly within its own allowance | What degradation do neighbours experience? |
| R | A copy of a backup taken before an erasure | Is the erased data still readable? |
**Output:** `docs/attacker-model.md`, completed 2026-08-21. It separates
credential-bearing tenant attacks, omitted-predicate accidents, SQL-capable
compromise, structural credential confinement, bounded co-resident saturation,
and both R4 erasure routes. It preserves the framework's correction that E3
stops accident, not compromise: resetting the tenant GUC after SQL execution
is recorded as E3's documented limit, not misreported as an E3 conformance
failure.

The core technique: run the same request as two tenants and compare.
- Provision two disposable tenants against a target service.
- Exercise its surface as tenant A; attempt every object identifier observed
from tenant B's context.
- Assert: B receives a denial or an empty result. **A well-formed 200
containing A's data is the finding**, and the harness must be built to notice
that rather than to notice errors — both of this estate's real regressions
produced ordinary-looking responses, a 403 and a 404, and nothing alerted.
- Capture evidence as a count and a schema shape, never as tenant data (T01).
**Acceptance:** a dated run record against every *applicable* E2 target. The
artifact is the run record, not a green tick. `tenant-engine` is registered
`not_applicable` for E2; that record is the artifact for that target.
`audit-core` remains the live E2 target and still needs a new admitted
engagement.
Implementation progress, 2026-08-22: `src/whitehat_security/differential.py`
performs owner/attacker/absent comparisons, detects fixture disclosure and
write-side state change, and persists only sanitized observations. Live entry
is `execute_authorized`, which requires a plane lease. Concrete route
inventories live in `probe-packs/`. Target honesty lives in `targets/`:
`audit-core` is applicable; `tenant-engine` is `not_applicable` (that is the
artifact, not a deferral); `flex-auth` is pending.
The 2026-08-21 production engagement IDs were cancelled without sending a
target request and are retired. A live audit-core run still needs a **new**
engagement, target-owner acknowledgement, provisioned `whitehat` namespace,

A probe that has only ever passed is not evidence.
Build known-bad fixtures — a service with a deliberately missing tenant
predicate — and confirm each probe fails against them. `rapp-postgres` verified
its drift check this way, by re-pinning to a bad digest and confirming exit 1;
the same discipline applies here and is not optional.
**Acceptance:** every probe in T03 demonstrated failing before any of them is
trusted passing.
Completed 2026-08-22. Five generic read/list/create/update/delete probes and
the three audit-core shaped probes pass the enforcing in-process fixture and
all produce findings when the tenant predicate is removed. Tenant-engine has
no applicable E2 identity, so its pack is not calibrated as if it were E2.
`make fixture-evidence` refreshes `evidence/offline-calibration.json`.
Target probes are still not trusted passing against a live service until a
new admitted engagement runs.

`rapp-postgres` ADR-0003 supplies an `rls_conformance` view and a template, and
states plainly that the platform's guarantee is **detection, not prevention**
a table created by a later migration ships without a policy until something
notices. This repo is that something.
- Query the conformance view on a cadence; any row is a finding.
- Attack what the view cannot see: a session that sets no GUC must read
nothing; a session with another tenant's value must see nothing; an insert
attributed to another tenant must be refused.
- Attempt the documented bypasses: a `SECURITY DEFINER` function owned by the
table owner, and a role holding `BYPASSRLS`.
**Cadence is the deliverable here, not a detail.** For a detection-based
control the interval between runs *is* the exposure window, and ADR-0003 leaves
the number to this repo. Set it, and state the resulting window in the record.
Implementation progress, 2026-08-21: the cadence is fixed at 24 hours plus run
and reporting latency, with event-triggered pre-promotion runs after schema,
role, RLS or security-definer changes. `src/whitehat_security/e3.py` encodes the
seven expected outcomes and keeps the SQL-compromise GUC reset labeled as E3's
documented limit. A live database run still requires its separate authorized
target and window.

The framework had to reword this artifact once already: its first draft
required proof that a saturating consumer "does not breach" another's
allowance, which shared infrastructure cannot provide.
What is achievable and therefore what this produces: a recorded baseline of
per-consumer resource usage; a run in which one consumer saturates its declared
allowance; evidence that the governance controls **bind**; and the degradation
co-residents experience, **measured and written down** rather than asserted
acceptable.
Runs inside a declared window per T01 — on a single-node rail with a six-
consumer connection ceiling, a saturation probe is an outage if run carelessly.
Implementation progress, 2026-08-21: `src/whitehat_security/capacity.py`
records baseline/loaded latency, errors and throughput per consumer, governor
binding, aggressor peak/ceiling and neighbour degradation. No live load has
been generated; the required operator-approved substrate window and ceilings
do not yet exist.

Findings leave this repo in one direction. A run produces: what was attempted,
under which attacker model, when, against which posture claim, and the outcome.
It carries no severity — that is `risk-nexus`'s.
A **passing** run is also reported. "The attacks we thought of did not work" is
the honest claim, and recording it dated is what lets anyone see how stale the
assurance has become.
Implementation progress, 2026-08-22: `schemas/run-report.schema.json` defines
the minimized evidence contract, `whitehat risk-message` renders both pass
and finding deliveries without severity, and `whitehat deliver` queues a
target report to `outbox/`. Fixture calibration is refused as target
assurance. Completion awaits the first authorized target report being
delivered to `risk-nexus`.
### T08 — Governed test plane

Completed 2026-08-22 as a repository contract, not a cluster provision:
- Target registration schema and catalog, including an honest
`not_applicable` state.
- Fail-closed admission: retired IDs, kill switch, approval class, namespace,
pinned digest, known-bad calibration, two identity handles.
- Credential broker interface that never returns secret values. The live
broker is unconnected and raises before any custody call.
- Rate watcher, lease cleanup, default-deny plane manifests, runner identity.
- Automatic outbox delivery of target reports only.
`ops-mason` still has to provision namespace, network policy and a real
custody projection after a new engagement ID exists. That provision is not
this task, and this task does not authorize it.

## Session cutoff — 2026-08-22
The coordinating session ended with the workplan deliberately **active**. T01,
T02, T04 and T08 are done. T03, T05, T06 and T07 remain in progress. The two
dated production engagement records were cancelled without sending any target
request; cancelled engagement IDs are terminal and must never be reused.
The offline instrument is implemented, calibrated, and plane-gated. The
estate still has to provision the cluster plane and a value-safe credential
broker before any live evidence exists. Resume only with new engagement IDs.
The exact completed scope is recorded in `docs/session-cutoff-2026-08-22.md`
and `docs/test-plane.md`.

## Risks
**The facility becomes the threat.** Mitigated by T01, and by holding no
standing privilege.
**Probes weaken silently.** A probe that starts passing after a change to
itself rather than to the system is a finding, not a fix. Probe changes are
reviewed as security changes.
**Green is mistaken for safe.** Every report states that a pass means the
attacks attempted did not work, not that the boundary holds.
**It drifts into fixing things.** The boundary in INTENT is load-bearing:
findings route out, work does not come in.
## Open questions
NetKingdom owns this; and a targeting rule, because scope widened Operator decision: whitehat is a NetKingdom facility, framed offensively - offence is how you find out, and a control is believed until someone tries it. Our own estate is one target among those we choose, not the only one. I had argued for the-custodian on independence grounds. The counter-argument is better: offensive security is security work and belongs with the security repo. The residual tension is real and recorded rather than argued away - NetKingdom now owns both the Tenancy Posture framework and the facility that tests conformance to it, which is NetKingdom assessing NetKingdom. The mitigation is that findings leave for risk-nexus under separate ownership rather than being resolved in place. Proportionate, not perfect, and worth revisiting if conformance findings start getting quietly closed. The reframe changes what this repo must guard against, and that is the substantial part of this commit. A facility that can be pointed at infrastructure we do not own is the single thing that could turn this repo from an asset into a liability, so the targeting rule is structural rather than cultural. No target without recorded authorization from whoever is responsible for it. Own estate in build mode has standing authorization; production needs its own, because the blast radius differs and so does the decision; anything we do not own needs written per-engagement authorization recorded here before a packet is sent. Three non-authorizations written down because each is a way teams talk themselves into it: a commercial relationship with the target, the target being publicly reachable, and believing the owner would obviously be fine with it. Unauthorized probing is criminal in most jurisdictions regardless of intent, and a white-hat facility that gets this wrong is an attacker with better paperwork. Two consequences. The authorization record is part of the finding - a report that cannot name what it ran under is not a finding, it is an incident. And scope creep during an engagement is prohibited: a probe that discovers an adjacent system stops at the boundary, because following the interesting thing is how an authorized test becomes an unauthorized one. Findings routing now forks. Our estate goes to risk-nexus and on to the owning repo. Any other target goes to that infrastructure's responsible party on the engagement's agreed terms, with risk-nexus still recording that it happened.

1. **Owner: NetKingdom** — settled 2026-08-17. Offensive security is security
work. The residual tension (NetKingdom owning both the Tenancy Posture
framework and the facility that tests conformance to it) is mitigated by
findings routing out to `risk-nexus` under separate ownership, and is
recorded in INTENT rather than argued away.
Seed INTENT and WP-0001: adversarial evidence facility Answers the Tenancy Posture question that has been unowned since the framework was drafted - who verifies a consumer's tenant boundary. Two repos were asked and both correctly declined as fleet-scope work. The work needed a home. Independence is the load-bearing property, not a nicety. rapp-postgres wrote fifteen probes against its own isolation model and found four real defects, which is good work and still the author checking their own homework. The probes worth having are the ones the author would not think to write, because the assumption that produced the defect produces the blind spot. That argues against NetKingdom owning this even though it owns the security canon: a facility verifying conformance to a framework must not report to the repo that owns the framework, or self-grading just moves up a level. Proposed owner is the-custodian, consistent with policy and risk. Needs confirmation. Two things stated because overclaiming is the failure this estate keeps catching in itself. "Automated" has a ceiling - the highest-impact cross-tenant findings need someone who understands what the data means, since a response can be well-formed, 200, fast, and contain another tenant's rows; so automate the reproducible and flag the irreducible for dated review. And a passing suite proves the attacks we thought of did not work, not that the boundary holds. The gap between those sentences is where breaches live. WP-0001 gates everything behind rules of engagement, because an automated facility probing systems without written scope is indistinguishable from the threat it models. No standing privilege, no BYPASSRLS, no superuser - an attacker would not have them and a probe holding them proves nothing. No exfiltration of real tenant data even as proof; a count and a schema shape are proof enough. And no saturation probing outside a declared window, because with a six-consumer connection ceiling that is an outage for every co-resident. T04 exists because a probe that has only ever passed is not evidence. Every probe must be shown failing against a known-bad fixture before it is trusted passing - the same discipline rapp-postgres used when it verified its drift check by deliberately re-pinning to a bad digest.

2. **Where probes run from.** In-cluster gives realistic network position;
outside gives independence from the substrate under test. Probably both,
eventually; pick one to start.
3. **Does a service get told it is being probed?** Announced runs are easier to
operate; unannounced ones test the alerting too. Build mode probably
announced, production probably not — which is itself a T01 decision.
