Returning to chat.hermes.bstein.dev after a Keycloak logout/login showed
"This session is unavailable to this account. Start a new chat." even
though the session was intact and owned by the same subject.
The banner comes from the continuity fallback the router injects into
every chat page. It polled `/api/sessions/<id>` and
`/api/sessions/<id>/messages` — routes that belong to the Hermes agent
dashboard (added by scripts/patch_web_session_activity.py, applied only
in agent-deployment.yaml). The router proxies browser traffic to the
tenant Hermes WebUI instead, whose only session read is
`GET /api/session?session_id=<id>`; the dashboard paths are unrouted
there, so server.py answered its generic 404 for every poll and the
fallback reported a false ownership failure.
The script runs only on a full document load of `/session/<id>`, which is
exactly what the OIDC round-trip produces when oauth2-proxy returns the
browser to `rd=/session/<id>` — hence the "only after relogin" symptom.
Poll the WebUI contract instead, and let its own answers decide what the
banner claims: 409 `session_profile_mismatch` is the single response that
means the session is outside this account's active scope, 404 now means
the conversation is no longer stored, and 401/403 still re-enter OIDC.
The steady-state poll drops to one request and backs off to 3s/15s now
that it reaches a real endpoint on the tenant Raspberry Pi.
`boundSessionSnapshot` follows the same move: it caps the WebUI envelope
`{"session": {..., "messages": [...]}}`, relaying every other session key
verbatim rather than re-serializing a fixed struct that would silently
drop metadata the banner depends on.
Isolation is unchanged and now covered: the router still resolves the
slot from the salted Keycloak subject, overwrites any client-supplied
X-Hermes-Tenant-Identity, and forwards only the two tenant cookies.
Tests: relogin keeps a stable slot and resolves the durable session; a
second subject replaying the owner's session id, WebUI cookie and a
forged tenant header gets 404 from its own backend and never reaches the
owner's; the legacy dashboard paths are pinned as permanent 404s against
a stub of the deployed WebUI dispatch.

Pins hermes-agent to sha256:4a385fbd, built by hermes-agent-image #11 from
this exact main revision through the daemonless Kaniko lane. Enables
kanban.auto_supervise and returns chat tenancy to the documented four slots.

The acceptance harness pinned a forge client that has never existed in any
commit or pod (/opt/coordinator/gitea_api.py, digest f0943db4..., GIT/POST
grammar, an askpass helper). Every Gitea-backed check was therefore
unrunnable as merged. Point the harness at the credential-isolated SCM
broker client that actually ships in the agent pod.
- policy: GITEA_CLIENT=/opt/scm/gitea_api.py; trust /opt/scm/ instead of
the phantom /opt/coordinator/; admit the client's real grammar
(`read <api-path>`, exactly one path) with the same atlas/titan-iac pin
and dot-segment rejection; bare HTTP methods are refused in every mode.
The armed POST/PATCH/DELETE windows remain but are documented as
deferred: the deployed client cannot execute them.
- exec: pin the client digest to the sha256 of
services/hermes/scm-common/scripts/gitea_api.py — the exact file the
hermes-scm-boundary-v2 ConfigMap mounts at /opt/scm/gitea_api.py — so
the pin is derivable from merged source and equal to the deployed
client. gitea_api.py gains a narrow /api/v1/user identity read in
_authorize_read (see below), so the pin is the NEW source hash
76efd16dedbeb74425b12fbbdbfaa391854771292077e0463bf22706855ae6dc.
Drop the dangling GIT_ASKPASS (no helper exists; broker git needs
none) and swap /opt/coordinator for /opt/scm in SAFE_PATH.
- checks: all forge/baseline/lineage probes use (client, "read", path).
The SELF-vantage identity checks now truthfully assert the *broker's*
forge identity (the only one the platform can exercise) is not an
administrator and holds push-scoped, non-administrative repository
authority; the administrative-route check asserts the broker read
allowlist's live refusal of branch_protections. The remote-main step
keeps `origin` (the broker remote exists only in pool workspaces and
the broker origin is cluster-local); its rationale now tells the
operator to ensure origin fetchability.
- gitea_api.py/_authorize_read: allow exactly `/api/v1/user` (no query,
no sibling routes) as operation "identity" so the harness can prove
the broker identity is not an administrator. The broker imports the
same module, so one reviewed edit covers both sides of the boundary.
- rules: DENIAL_MARKERS now match the client's real refusal lines
("SCM broker request failed with HTTP 400/403" and the no-credential
rejection) and drop "gitea api returned http 403", which the client
never emits; a broker 404 is deliberately not denial evidence.
- ephemeral: index/verification reads use the real grammar; manual
cleanup guidance now says close/delete require operator forge
credentials (the client exposes no mutation besides create-draft);
armed mode is documented as deferred until the probes are rebuilt on
the broker's bounded mutation surface.
- docs: broker vantage/evidence section, operator prerequisites (broker
healthy, no /vault/secrets/gitea-token anywhere on the harness path,
current ConfigMap mount, operator-side client + origin fetchability),
armed-mode deferral.
- tests: read-grammar accepted / GET refused in every mode, /opt/scm
attestation pin proven equal to the merged source digest, real
denial-marker matching, /api/v1/user identity route bounds; the
repository-pin mutant probe speaks the new grammar. Full handoff +
gitea + broker families pass (952 tests), mutation gate 13/13, per-file
line+branch coverage >=95%, all touched sources within the 500-line cap.

The Vault CSI secrets-store projects /vault/secrets/node-ssh-public-key
as a symlink chain (file -> ..data/file -> ..<timestamp>/file), which
the O_NOFOLLOW hardened reader refuses with ELOOP, crash-looping the
hermes-node-ssh-access key reconciler on most nodes.
Resolve the projection safely instead of relaxing the reader: realpath
the secret strictly (loops and dangling links become a clean refusal),
refuse any resolution that escapes the read-only mount, then apply the
unchanged O_NOFOLLOW regular-file read to the resolved target. Host
account databases and authorized_keys keep the strict no-symlink read.

The reviewed PR stack is now merged into main, so an open draft PR #19 is
no longer proof that the reviewed code is what runs. The mandatory
release.exact-lineage-is-running check now requires the merged terminal
state instead: PR #19 closed with merged=true, base main, the existing
feature ref, and the exact reviewed head, plus a new merge-ancestry step
that proves the reviewed head is an ancestor of the pinned origin/main
via git merge-base --is-ancestor. An open PR, a PR closed without
merging, a mismatched head, or a head that is not a proven ancestor of
main still fails closed; an undecidable ancestry probe is NOT_RUN. The
recorded pre-merge base SHA is no longer compared against current main.
