Apply GH-DEC-2026-015/016 and the audit-core registration; both blockers cleared

Origin and evidence path both landed today.

T07 origin: railiance-apps deployed decisions.coulomb.social and corrected the
hostname in this repo — not the decide.coulomb.social this workplan proposed.
Verified here rather than taken on report: both paths 200, TLS verify 0, Let's
Encrypt cert valid to 2026-12-09.

T08: audit-core registered the source with every field as proposed and landed
the detection half. INFD-IN-0003 closed. Their refinements booked — reconciliation
on the high-volume class too, since rate detects a stream stopping but never a
stream missing the particular renders that mattered, which is exactly our threat
model; and PR-12, the custody locator must be a stable non-secret identifier
because redact scans data and an existence declaration arriving without its
pointer looks complete while being useless.

INFD-IN-0004 ruled as GH-DEC-2026-015: gate-house reversed itself and nesting is
permitted for this pair. The decisive ground was not the cycle argument we led
with — our binding slice canonicalizes principal and target, two of the five
digest fields, so co-reference left us performing a partial recomputation of one
act in a second vocabulary, closer to the translation R3 forbade than nesting
is. Our ordering objection was withdrawn as mistaken.

The permission is conditioned and NOT ACTIVE until approval-engine states its
presentation exclusion as normative and tested. layer.yaml is deliberately
unchanged and carries nesting_permission_active false — we do not activate on
our own initiative.

GH-DEC-2026-016 ruled NC-03. Its §5 is live rather than hypothetical and is
booked as PR-11: principal_type: human is a property of the client registration,
structurally the same shape as the gap-route tenant, so a human-in-the-loop
control must not be discharged on it as verified humanity.

T07 stays progress: the submission to key-cape is written but unsent, blocked by
the local permission classifier rather than by any repository.

+## 8e. Cadence — declared, and now supportable
+
+`audit-core` registered this source as proposed (`AUDIT-IN-0003`,
+`docs/informed-decision-source-registration.md`) and landed the detection half
+(`AUDIT-WP-0009` T04/T06/T07). The cadence can stop being described as
+declared-but-not-operating once heartbeats are flowing.
+
+**Per class, not per source** — the shape this repository argued for and
+`audit-core` adopted. A per-source heartbeat from a mixed-volume emitter is
+satisfied by its chattiest class and says nothing about the quiet,
+security-relevant one, which is the only reason heartbeats exist.
+
+| Class | Volume | Heartbeat | Reconciliation |
+| --- | --- | --- | --- |
+| `presentation` | one per render | yes — legitimately silent for days at Stage 1 | yes |
+| `disposition` | low, security-relevant | yes | yes |
+| `stance_application` | low, security-relevant | yes | yes |
+
+Reconciliation applies to **every** class including the high-volume one: rate
+detects a stream stopping, never a stream missing the particular renders that
+mattered.
+
+A heartbeat is an **ordinary event** — same envelope, same append-only custody,
+same chain. Deliberately so: a heartbeat stored outside the chain would be the
+one record that could be back-dated.
+
+Note `no_heartbeat_since_registration`: declaring a heartbeat and never sending
+one is **its own finding**, not a skip.
+
+### The bound on both controls
+
+Reconciliation compares `audit-core`'s counts against counts we compute from our
+own state. **Where the emitter is compromised, both controls agree with it** — a
+compromised surface suppresses the event and its own count together, and emits a
+truthful-looking `nothing-to-report`.
+
+Both cover loss, outage, drain failure and accident, which is most of what
+actually goes wrong. **Neither covers the residual we already declare**, and
+neither may be described as covering it. Closing it needs an observer
+independent of the emitter, which §16 put outside `audit-core`'s scope.
+
+### Tenant provenance is not in the envelope
+
+`audit-core`'s tenant is not an identity claim they resolve; it is a value our
+credential is permitted to write, checked by exact string equality. Recording a
+route in the audit event would be them restating something they did not observe
+— the same error as claiming an event occurred. It lands in the registration
+document instead, whose authority is `GH-DEC-2026-013`'s bounded gap rather than
+a populated directory record. If that gap closes, the entry is revisited rather

+**PR-11 [rev-3] — A human-in-the-loop control is never discharged on an

+`GH-DEC-2026-016` requires that where an approval is *declared* as discharging a
+human-in-the-loop control, the approver must be a human principal and
+`approval-engine` must refuse at bind time. Its §5 lands here: what makes a
+principal `human` belongs to the identity layer and **inherits A-16** — if
+`human` is reachable by two routes, the control must not be discharged on a
+registration-supplied claim. Refusing a service principal while accepting an
+unverified assertion of humanity moves the defect rather than closing it.

+**This is live for us, not hypothetical.** `principal_type: human` is a property

+`tenant`. Until its provenance is distinguishable, this surface treats it as
