fix(escalation): record votes in approve/deny; fix quorum always evaluating to 0

[Imran Siddique (imran-siddique)]

Summary

• InMemoryApprovalQueue.approve() and deny() were setting req.decision and req.resolved_by but never appending to req.votes
• EscalationHandler.resolve() evaluates quorum by summing req.votes -- with an always-empty list the count was 0, resetting a correctly-resolved decision back to PENDING and falling through to the timeout default
• Fix: append the vote tuple (approver, verdict, timestamp) to req.votes before any decision logic; deduplicate by approver so a single reviewer cannot satisfy quorum multiple times

Fixes #3126

Changes

agent-governance-python/agent-os/src/agent_os/integrations/escalation.py

• approve(): append (approver, "ALLOW", datetime.now(...)) to req.votes before setting decision; skip duplicate votes from the same approver; allow additional votes to be recorded after decision is already final
• deny(): same pattern for "DENY" verdict

agent-governance-python/agent-os/tests/test_escalation.py

• Renamed test_double_approve_fails to test_double_approve_same_approver_rejected (clarifies the dedup semantics, not "already resolved")
• Added test_second_approver_vote_recorded -- second approver's vote appended, both visible in req.votes
• Added test_votes_recorded_on_approve / test_votes_recorded_on_deny -- assert votes list populated with correct approver and verdict
• Added TestQuorumResolution class: quorum met resolves ALLOW, quorum not met times out to DENY, duplicate approver vote rejected and does not satisfy quorum

Test plan

• All 26 escalation tests pass (pytest tests/test_escalation.py)
• test_quorum_met_resolves_allow: quorum=1, single approver, resolves ALLOW
• test_quorum_not_met_times_out: quorum=2, 1 approver, times out to DENY
• test_duplicate_approver_does_not_satisfy_quorum: second call from same approver returns False, votes list length stays at 1

TL;DR: 0 blockers, 1 warning. Changes improve vote tracking and quorum logic but require additional test coverage for edge cases.

1	Warn	Missing test for quorum resolution when quorum is exactly met (edge).	agent-os/tests/test_escalation.py and TestQuorumResolution class

Action items:

1. Add a test case to verify quorum resolution when the number of approvals exactly matches the quorum requirement.

API Compatibility

Severity	Change	Impact
High	approve() and deny() methods in InMemoryApprovalQueue now require an approver argument to be non-empty and unique for each vote.	Existing code that calls these methods without providing a valid approver argument or with duplicate approvers will break.
High	approve() and deny() methods now append votes to req.votes and enforce deduplication by approver.	Any reliance on the previous behavior (e.g., no vote tracking or allowing duplicate votes) will break.
Medium	Behavior of quorum evaluation in EscalationHandler.resolve() has changed due to the enforcement of vote tracking and deduplication.	Existing workflows relying on the previous quorum evaluation logic may behave differently.
Medium	Tests that directly manipulated req.votes in test_security_hardening.py have been refactored to use the updated approve() and deny() methods.	Custom test setups or mocks that relied on direct manipulation of req.votes will need to be updated.

DCO sign-off is needed on the 8 commits this PR presents to GitHub. The commits themselves are correct; the sign-off is purely a procedural fix.

Fastest path to unblock:

git checkout fix/escalation-quorum-votes-3126
git pull --rebase origin fix/escalation-quorum-votes-3126

# Create clean 2-commit version from main
git checkout -b fix/escalation-quorum-votes-3126-dco main
git cherry-pick -s 6b4788ff  # fix(escalation)
# resolve edu-k12 conflict: just git add examples/policy-templates/edu-k12.yaml
git cherry-pick -s b3904c0b  # fix(tests)
git push origin fix/escalation-quorum-votes-3126-dco:fix/escalation-quorum-votes-3126 --force-with-lease

This reduces the PR to 2 commits, both with Signed-off-by: Imran Siddique <imran.siddique@opaque.co>. The diff stays exactly the same (same 4 files: escalation.py, test_escalation.py, test_security_hardening.py, edu-k12.yaml). The policy gate and CI tests should pass once the edu-k12/quorum fixes in this PR land (they self-bootstrap).

[MohammadHaroonAbuomar]

The quorum fix itself is correct, idempotent, and thread-safe.

The examples/policy-templates/edu-k12.yaml hunk needs to be dropped from this PR. Main now has newer fixes to the same three regexes (lazy .*?, optional (to\\s+|an?\\s+)?, the extra |information keyword) and merging this would overwrite them. It is also unrelated to the escalation fix.

Separately, this fix surfaces a pre-existing issue worth a follow-up: resolve() wakes on the first vote, runs the quorum check once, and falls through to default_action without waiting the remaining timeout for vote 2 of N (escalation.py:176, :424-431). Not introduced here, but now reachable.

Minor: approver: str = "" default (escalation.py:166,184) means one anonymous vote counts toward quorum. Consider rejecting empty when quorum is in play.

[Imran Siddique (imran-siddique)]

Thanks for the detailed review MohammadHaroonAbuomar.

edu-k12.yaml: Dropped from this PR. Reverted to main's version -- the newer regex fixes already in main are preserved.

Empty approver: Added if not approver.strip(): return False to both InMemoryApprovalQueue.approve() and deny(), so a blank identity can never count toward quorum. Updated three existing tests that called approve() without an explicit approver and added test_empty_approver_rejected_on_approve / test_empty_approver_rejected_on_deny.

resolve() timing issue: Acknowledged -- resolve() wakes on the first vote and runs the quorum check once, falling through to default_action without waiting the remaining timeout for additional votes. Not introduced by this PR but now reachable with quorum configured. Opening a follow-up issue.

[Imran Siddique (imran-siddique)]

MohammadHaroonAbuomar please merge this when u have time. All tests passing.

[Imran Siddique (imran-siddique)]

MohammadHaroonAbuomar thanks for the review. Addressed your change request: the examples/policy-templates/edu-k12.yaml hunk is dropped entirely, the branch no longer touches that file, so main's newer regex fixes (lazy .*?, (to\s+|an?\s+)?, the |information keyword) are preserved. I also rebuilt the branch as a single signed commit on top of current main, so DCO is green again. Could you re-review when you get a chance?

Jack Batzner (@jackbatzner) Ricky Gummadi (@Ricky-G) the quorum fix is correct-in-substance per Mohammad's review and now CI-clean. The only remaining gate is policy/maintainer-approval, which I can't clear myself, my maintainer approval still isn't registering. Could one of you approve? And if possible, please re-add me to the maintainer group so this stops blocking my PRs.

[Imran Siddique (imran-siddique)]

Closing this as superseded. The fix is already present on main: escalation.py, test_escalation.py, and test_security_hardening.py on main are identical to this branch, and the vote recording in approve/deny, the quorum fix, and the empty-approver rejection are all in place (escalation.py:171/175/191/195). No separate merge is needed here. Thanks to the reviewers for the look.
