- Implement an approval token system to handle controlled execution permissions via the policy engine, including support for delegated approvals. - Add a session compaction pipeline (compact_pipeline) to cut down on runtime memory usage and message overhead. - Connect both the approval and compaction systems into the core runtime execution path (specifically updating the Trident engine). - Update the CLI and test contracts to match these changes. Note: This is a major structural change affecting the policy, execution, and session lifecycle layers.

Pull request overview
Note
Copilot was unable to run its full agentic suite in this review.
This PR modernizes Rust code patterns (Option handling, derives, small refactors), introduces a new “compact_pipeline” module in runtime, and significantly rewrites the approval-token system.
Changes:
- Replace
map_orpatterns withis_some_and, simplify control flow, and apply clippy/allow attributes in a few places. - Add
runtime::compact_pipelineand re-export its types/functions fromruntime::lib. - Rewrite
runtime::approval_tokenswith a new ledger/audit model and token lifecycle APIs.

Maintainer NO-GO: closing this PR because it is not safe to merge in its current form. Specific blockers still present in the current diff:
Please do not re-open this exact PR. A replacement should restore the security invariants first, include focused tests for the approval-token failure modes above, and prove any compaction change preserves enough state for continuation before being exported as runtime API. |
