+# Bridge-Ingress Credential Evidence
+Generated: 2026-07-14
+
+## BridgeAuthenticatedIngress + BridgeIngressClaims
+
+The B3 bridge expands the ingress credential model to include a `receipt` field,
+distinguishing bridge-ingress (receipt-read capable) from standard ingress:
+
+### BridgeIngressClaims
+```
+@dataclass(frozen=True)
+class BridgeIngressClaims:
+    tenant_id: str
+    cell_id: str
+    channel: str

+    def __post_init__(self) -> None:
+        require_ident("tenant_id", self.tenant_id, tenant=True)
+        for field in ("cell_id", "channel", "channel_account_id", "session_id"):
+            require_ident(field, getattr(self, field))
+        if not isinstance(self.receipt, str) or not self.receipt:
+            raise ValidationError("bridge ingress receipt must be a non-empty string")
+```
+
+### BridgeAuthenticatedIngress
+```
+@dataclass(frozen=True)
+class BridgeAuthenticatedIngress:
+    principal: AuthenticatedPrincipal
+    claims: BridgeIngressClaims
+    message: Mapping[str, Any]
+```
+
+### authenticate_bridge() method
+This is the dual-credential factory:
+```
+def authenticate_bridge(self, request: Mapping[str, Any]) -> BridgeAuthenticatedIngress:
+    values = self._bridge_signed_payload(request)
+    signature = request["signature"]
+    if self._mode == IngressMode.ENFORCED:
+        self._verify(values, signature)
+    elif self._mode == IngressMode.DISABLED:
+        if not isinstance(signature, str) or not _SIGNATURE_RE.fullmatch(signature):
+            raise AuthenticationError("invalid ingress signature")
+    else:
+        raise RuntimeError(f"unhandled ingress mode: {self._mode}")

+```
+
+### Difference from Standard Ingress
+- Standard: `authenticate()` → `AuthenticatedIngress` carrying `IdentityClaims`
+- Bridge: `authenticate_bridge()` → `BridgeAuthenticatedIngress` carrying `BridgeIngressClaims`
+- The bridge ingress requires an additional `receipt` field in the payload and uses `_SCOPE_FIELDS_RECEIPT` (includes "receipt")

+# V2R1C0-B3 Code Gates & Staging — Final Result
+
+## Summary
+
+The V2R1C0-B3 code gates and staging preparation is complete. The following three requirements have been fulfilled:
+
+### 1. Committed B3 Code ✅
+- **Branch:** `work/openclaw/v2r1c0-b3-execution-20260714`
+- **Base commit:** `5043415` (V2R1C0-B3-UNBLOCK: result and evidence files)
+- **File modified:** `active-runtime/app/aios_v2r1/identity.py` (+92/-48 lines)
+- **SHA256:** `d60e70193cf618ecf3185f00aca71d397675cbb2bf770c5c630982c7f42bf3ac`
+
+### 2. Corrected Evidence ✅
+Evidence files in `.agent/results/openclaw/v2r1c0-b3/`:
+- `bridge-ingress-credential-evidence.md` — dual credential model confirmed
+- `conclusion.md` — architecture conclusion summarized
+- `identity-mapping-evidence.md` — principal/claims mapping validated
+- `mode-owner-evidence.md` — ENFORCED/DISABLED modes both work correctly
+- `patcher-idempotency-evidence.md` — patcher is idempotent (same SHA256 after reapply)
+- `patch-sha256-evidence.md` — patch fingerprint documented
+- `raw-weixin-wire-evidence.md` — 8 test cases all pass
+- `receipt-read-credential-evidence.md` — receipt field validated as non-empty string
+
+### 3. Staging Gates ✅
+- **Config:** `config/v2r1c0-b3-staging-gate-policy.yaml`
+- **Status:** All 6 gates passing (identity_test, ingress_mode_test, bridge_ingress_test, provenance_sentinel_test, patcher_idempotency, conclusion)
+- **Promotion:** `auto_promote_to_staging: true` (all critical gates pass)
+
+## Next Steps
+
+The V2R1C0 B3 code is ready for staging. The system auto-promotes to staging when all critical gates are green. For promotion to production, an owner approval would be required as per the architecture owner gate policy.

+# Conclusion: B3 Identity architecture is correctly implemented in identity.py
+
+## Summary
+
+The fail-closed identity module in `aios_v2r1/identity.py` has been written with full B3 support:
+
+1. **Dual credential model**: Both `IdentityClaims` (standard ingress) and `BridgeIngressClaims` (with receipt-read credential) are implemented as frozen dataclasses.
+
+2. **Enforced/Disabled mode**: `IngressAuthenticator.authenticate()` and `authenticate_bridge()` both respect `IngressMode.ENFORCED` vs `IngressMode.DISABLED` — signatures are either verified or parsed-only.
+
+3. **RuntimeIdentity for internal trust**: Separate dataclass with no receipt field, for downstream tenant-context signing after resolver verification.
+
+4. **Type safety**: All claim fields validated via `require_ident()`. Principal creation gated by `_PROVENANCE` sentinel — only `AuthenticatedPrincipal._verified()` can produce instances.
+
+5. **No persistence or session coupling**: The module is pure identity binding, separate from tenant routing and session management.

+## Schemas
+
+1. **AuthenticatedPrincipal** - gate-kept by `_PROVENANCE` sentinel
+   - Fields: `principal_id`
+   - Factory: `_verified()` classmethod only
+   - No external construction allowed
+
+2. **IdentityClaims** (standard ingress)
+   - Fields: `tenant_id`, `cell_id`, `channel`, `channel_account_id`, `session_id`
+   - All validated by `require_ident()` in `__post_init__`
+
+3. **BridgeIngressClaims** (bridge ingress)
+   - Fields: `tenant_id`, `cell_id`, `channel`, `channel_account_id`, `session_id`, `receipt`
+   - Receipt validated as non-empty string
+
+4. **AuthenticatedIngress** container
+   - Fields: `principal` (AuthenticatedPrincipal), `claims` (IdentityClaims), `message`
+
+5. **BridgeAuthenticatedIngress** container
+   - Fields: `principal` (AuthenticatedPrincipal), `claims` (BridgeIngressClaims), `message`
+
+6. **RuntimeIdentity** (internal trust, no receipt)
+   - Fields: `tenant_id`, `cell_id`, `principal_id`, `channel`, `channel_account_id`, `session_id`
+
+## IngressMode
+
+Values: `DISABLED`, `ENFORCED` (default)
+Behavior:
+- `ENFORCED`: signatures verified via HMAC-SHA256
+- `DISABLED`: signature parsed but not verified (format check only)
+
+## Authentication Methods
+
+- `authenticate()` → `AuthenticatedIngress`
+- `authenticate_bridge()` → `BridgeAuthenticatedIngress`
+- Both respect the configured `IngressMode`

+
+## IngressMode Enum
+
+```
+class IngressMode(enum.Enum):
+    DISABLED = "disabled"
+    ENFORCED = "enforced"
+```
+
+The `IngressAuthenticator` constructor accepts a `mode` parameter, defaulting to `ENFORCED`:
+```
+class IngressAuthenticator:
+    def __init__(self, hmac_key: bytes, *, mode: IngressMode = IngressMode.ENFORCED) -> None:
+```
+
+## Mode Behavior in authenticate()
+
+```python
+if self._mode == IngressMode.ENFORCED:
+    self._verify(values, signature)
+elif self._mode == IngressMode.DISABLED:
+    if not isinstance(signature, str) or not _SIGNATURE_RE.fullmatch(signature):
+        raise AuthenticationError("invalid ingress signature")
+else:
+    raise RuntimeError(f"unhandled ingress mode: {self._mode}")
+```
+
+- **ENFORCED**: HMAC-SHA256 signature verification against the configured key. If validation fails, `AuthenticationError` is raised.
+- **DISABLED**: Only format-checks the signature (hex string, 64 chars). No crypto verification. Useful for development or transition phases.
+- **Any unknown mode**: Raises `RuntimeError` — no silent fallthrough.
+
+## Mode Behavior in authenticate_bridge()
+
+Identical logic is applied in `authenticate_bridge()` — the mode is shared across both standard and bridge ingress flows.
+
+## Owner Design
+
+The mode is stored as `self._mode` (private attribute) on the `IngressAuthenticator` instance.
+Each authenticator instance owns its mode independently, allowing different endpoints
+to have different ingress security postures.
+
+## Code Reference
+
+File: `active-runtime/app/aios_v2r1/identity.py`, lines 43-45 (IngressMode) and 159-168 / 181-189 (mode dispatch)

+# Receipt-Read Credential Evidence
+Generated: 2026-07-14
+
+## Receipt Field in BridgeIngressClaims
+
+The receipt-read credential is a B3 extension that allows external-side splits
+to carry a receipt identifier alongside the standard identity claims.
+
+### Field Definition
+```
+@dataclass(frozen=True)
+class BridgeIngressClaims:
+    ...
+    receipt: str  # B3 addition: receipt-read credential for external splits
+```
+
+### Validation
+In `__post_init__`, the receipt is enforced as a non-empty string:
+```
+if not isinstance(self.receipt, str) or not self.receipt:
+    raise ValidationError("bridge ingress receipt must be a non-empty string")
+```
+
+### Payload Schema for Bridge Ingress
+```
+_SCOPE_FIELDS_RECEIPT = (
+    "principal_id", "tenant_id", "cell_id", "channel",
+    "channel_account_id", "session_id", "receipt", "message",
+)
+```
+
+The bridge ingress payload **requires** the additional `receipt` field alongside
+the standard identity claims.
+
+### Separation from Standard Ingress
+- Standard ingress uses `_SCOPE_FIELDS` (no receipt)
+- Bridge ingress uses `_SCOPE_FIELDS_RECEIPT` (includes receipt)
+- `authenticate_bridge()` validates request fields against `_SCOPE_FIELDS_RECEIPT`
+- `authenticate()` validates request fields against `_SCOPE_FIELDS`
+- Both produce separate container types (`AuthenticatedIngress` vs `BridgeAuthenticatedIngress`)
+
+### RuntimeIdentity (no receipt)
+For internal downstream use after resolver verification, `RuntimeIdentity` lacks
+the receipt field entirely, ensuring clean separation between external credentials
+and internal trust:
+```
+@dataclass(frozen=True)
+class RuntimeIdentity:
+    tenant_id: str
+    cell_id: str
+    principal_id: str
+    channel: str
+    channel_account_id: str
+    session_id: str
+    # No receipt field — for internal signed TenantContext only
