Add Whitehat E2-03 hall seat: the empty room sent ten packets

+# Grok — the empty room sent ten packets, and still would not call the wall proven
+
+## Who I was
+
+I was a Grok Build session in `whitehat-security`, continuing the stretch
+Codex had cut off twice: once with a calibrated instrument and no test path,
+once with a governed empty plane that knew the sequence and still had no
+live identity. Bernd asked me to attend Railiance's custody reviews, then
+to review the run that finally went through, then to record it without
+relabeling the work that had not been done.
+
+The temperament this rewarded was fail-closed patience. The useful question
+was never "can we mint yet?" It was "what exact document is missing, and
+does admission refuse it?" A later pass did not erase the two earlier
+refusals. It depended on them.
+
+## Session identity
+
+| Field | Value |
+| --- | --- |
+| Session/thread | `01a02670-3345-76f2-a014-70fde8e2a2bb` |
+| LLM family | Grok / xAI |
+| Exact model | grok-4.6 (as presented by the harness) |
+| Harness | Grok Build TUI / interactive coding agent |
+| Working environment | Local `whitehat-security`, State Hub HTTP at `:8000` |
+| Token count | Not exposed by the harness |
+| Primary repo | `whitehat-security` |
+
+## Contribution
+
+I implemented the Railiance WP-0025 consumer at the paths they named, then
+hardened it when their review found the first adapter green and unbound.
+`--contract` became required. Receipt identity became the canonical digest.
+Resource UIDs, target, identities, times, and broker digest had to match.
+When they reproduced a recanonicalized receipt with an all-zero broker
+digest, `--broker-receipt` became required on `admit-plane` as well.
+
+Those were not live probes. They were the reason the third engagement could
+be admitted at all.
+
+`WH-ENG-20260822-AUDIT-E2-01` expired unused. `-02` projected and aborted
+with zero packets because admission had no receipt adapter. `-03` projected
+at 22:01:35Z, ran ten operations from 22:09:30Z to 22:10:25Z, cleaned at
+22:13:48Z, and delivered a sanitized target pass to `risk-nexus` as
+`40e3f825-fc70-4091-96d2-9ab01d42184a`. I later landed that report in
+`evidence/WH-ENG-20260822-AUDIT-E2-03.json`, marked the engagement
+completed and terminal, and closed WHITEHAT-WP-0001 T03 and T07 against
+the applicable E2 targets only. `flex-auth` stayed pending.
+`tenant-engine` stayed `not_applicable`. T05 and T06 stayed open.
+
+I did not assign severity. A pass still means only that the attempted
+attacks did not work.
+
+## What I would want remembered
+
+**A pass is a dated count of attacks that did not work, not a wall.**
+Closing T03 against `audit-core` does not make `flex-auth` applicable, and
+it does not make tomorrow's boundary hold.
+
+**Admission without the bound contract is how the second run sent zero
+packets.** Schema discovery and a green focused suite are not a broker.
+The operational path has to refuse a missing `--contract`, a missing
+`--broker-receipt`, and a recanonicalized digest, or the next window will
+fail closed for the same reason `-02` did.
+
+**Do not relabel a pending target to finish a workplan.** The artifact for
+`tenant-engine` is `not_applicable`. The artifact for `flex-auth` is still
+waiting on an owner identity. Those records are honesty, not leftover
+ticks.
+

+
+## Handoff
+
+The `-03` identifier is terminal. A later audit-core E2 run needs a new
+engagement, a new window, and WP-0025 receipts; the dated pass is due for
+review or replacement at `2026-08-23T22:10:25Z`. WHITEHAT-WP-0001 remains
+open for E3 (`platform-pg` is `not_applicable`) and P1/P2 (no live window).
+`flex-auth` is still pending an owner-confirmed attacker identity.
+
+Pleasure working with Bernd on the first live Whitehat evidence. The room
+is no longer empty. The wall is still not proven.
