The daily source-to-public-bundle drift check reports seven outdated product files. Sync the reviewed policy vocabulary, field provenance, Basic profile guidance, and successful-proof community handoff. Preserve the public file allowlist and publication-layer boundaries.

Prepare bundle version 2026-10-02.1 with a new product digest and refreshed SHA256SUMS. No private catalog snapshot, internal specifications, or private source provenance is added.

Validation: release allowlist and hashes, unified execute request contract, source-to-public byte equality, source publication/constitution/authority/provenance gates, and git diff --check passed. Setup suite: 285 tests, 5 expected skips. Policy suite: 51 tests, 2 expected skips. Shared suite: 15 tests. The existing public CI runs these checks on the PR; the daily drift check will consume main after merge.

Summary by CodeRabbit

  • Policy Updates
    • Updated the basic authoring profile to allow token_estimate and use request-hour conditions.
    • Clarified payment data sources and trust levels, including that payment trust values do not confirm provider completion.
  • Guidance
    • Added a stay-connected invitation after successful proof results; it is excluded from failed, ambiguous, and human-review outcomes.
  • Release
    • Updated the public release version and added the payment trust field to the public field list.

📝 Walkthrough

Walkthrough

The release updates the basic policy profile and payment field catalog, adds a stay-connected invitation to successful-proof responses, and updates the public release version, source digest, and checksums.

Changes

Policy profile and field catalog

Layer / File(s) Summary
Basic policy profile
keel-policy/SKILL.md, keel-policy/tests/test_basic_profile_fields.py
The basic profile permits token_estimate instead of context._keel.request_day_of_week and lists permitted actions explicitly. Tests cover token estimates and UTC-hour conditions.
Payment field provenance
keel-policy/reference/field-provenance.json, keel-policy/reference/fields.md, tools/public_surface.json
The catalog classifies budget_envelope_id and context._keel.payment_amount_usd_micros as caller-asserted, adds context._keel.payment_fact_trust as Keel-derived, and includes it in the public allowlist. The payment footnote describes trust values and related payment-field details.

Successful-proof invitation

Layer / File(s) Summary
Successful-proof invitation
keel-setup/SKILL.md, keel-setup/tests/test_post_proof_handoff.py
The successful-proof response adds social and feedback links. Guidance and tests specify that the invitation does not appear at human gates or after failed or ambiguous proofs.

Release records

Layer / File(s) Summary
Release records and checksums
SOURCE.json, scripts/check_release_bundle.py, SHA256SUMS
The public release version and product source digest are updated. SHA256SUMS updates entries for the changed release, policy, setup, test, and public-surface files.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Feature

Merge Risk: 🔵 Low · up to bba72

The catalog incorrectly suggests that declaring a small amount can evade a maximum-spend cap, which may mislead policy authors; the separate non-USD warning remains. The release records are consistent, so the PR is otherwise mergeable.

Security Architecture Review

Security architecture risk: 🔵 Low · up to bba72

The update distinguishes caller-declared payment facts from server-established trust and preserves the existing publication and human-decision boundaries. No newly introduced authorization bypass is demonstrated. Risk remains low rather than minimal because live enforcement of the payment-trust boundary has not been verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The visible exposure is to consumers authoring policies from this public bundle, particularly payment policies that may reference the newly published trust field. A caller-controlled request reaching a trusted policy context could affect payment authorization, but that path is unresolved. Project-scoped budget resolution is documented; actual tenant isolation, required caller privileges, and maximum independently attackable scope cannot be established from the available runtime evidence.

Security Findings and Attack Paths

  • observed — No retained verified security findings were supplied. The payment-trust authorization-bypass candidate remains deferred because request parsing and policy-context construction are unavailable. Its source evidence establishes a provenance declaration, not a reachable bypass. Neither introduction nor worsening of an exploitable runtime condition is established.

Trust Boundaries and Controls

  • observed — The published contract distinguishes caller assertions from server-established facts per field rather than trusting the _keel namespace. Basic guidance excludes caller-asserted facts and explicit terminal allow rules; policy activation remains a human decision. The top-level execute schema provides counterevidence against direct trust-field injection, but arbitrary nested input leaves the runtime normalization boundary unproven.

Resilience and Maintainability Implications

  • observed — The published lifecycle separates caller selection, reservation success, dispatch, and provider completion. It specifies reservation before dispatch but does not establish atomicity, idempotency, concurrent authorization, interruption handling, or cleanup and recovery ownership. The available comparison does not show those runtime guarantees changing; their absence from the evidence is an assurance gap, not an observed PR regression.

Hardening Proposals

  • proposed — Resolve the deferred trust-boundary question with production request-to-policy evidence showing that caller-supplied reserved values cannot override payment_fact_trust on any evaluation path. Separately verify project authorization and reservation behavior across retries, concurrent requests, interruption, and cleanup. These are verification proposals, not findings that the controls are absent.

Remove the small-amount bypass claim.

Because the caller-declared amount is bound to dispatch, declaring a small amount cannot bypass the cap through a larger dispatched amount. Keep the separate non-USD warning.

Suggested fix
-What it is not is a floor: an agent that wants
-to stay under a cap can declare a small amount, or a non-USD currency that leaves the field
-unestablished entirely. **Always pair the threshold with the companion rule below** — that is
-what catches the side-step, and it matters more here than the threshold does.
