Problem

gitea_assess_pr_sync_status can permanently block an otherwise merge-ready pull request when the commit has no status contexts.

This was reproduced on PR #750 at exact head e349839fd739e10af2df9c0f429ac487e8ca8b9d, based on master fdab6b6c69717d32a0d50e233413cf09be83f6e8.

PR #750 was open and mergeable, zero commits behind master, and approval #466 was valid at the current head. Nevertheless, the assessor returned:

checks_status=pending
recommended_next_action=blocked
reason: required checks are not finished

No caller-supplied or invented checks_status value was used.

Diagnosis

The production dataflow has several related defects:

gitea_mcp_server.py:15736-15739

The wrapper reads the combined commit-status response and takes its state value directly. Gitea can report state: pending when the contained status-context collection is empty.

The code does not inspect the number of status contexts. Its fallback to checks_status="none" is effectively unreachable for a valid combined-status response containing a truthy state.
pr_sync_status.py:76

checks_required defaults to True.
gitea_mcp_server.py:15561-15569

The MCP wrapper exposes no sanctioned input or derived value for checks_required, and production callers do not pass it.
gitea_mcp_server.py:15370-15405

The existing branch-protection reader handles the current-base rule but does not derive status-check requirements from fields such as enable_status_check or status_check_contexts.

The result is that the assessor cannot reliably distinguish:

real required checks that are pending;
checks that are not required;
no checks configured;
an empty combined-status response with no executing producer.

At both PR #750's head and base, read-only repository inspection found no Gitea Actions, GitHub Actions, Woodpecker, Drone, or other apparent CI workflow configuration capable of producing a status context.

Impact

The canonical merge workflow requires recommended_next_action=merge_now before merger acquisition. Therefore, a commit with no status contexts can become permanently blocked even though no check is running and waiting cannot change the result.

PR #750 must remain unmerged until this defect is handled through the sanctioned workflow. The defect must not be bypassed by supplying a fabricated checks_status or checks_required value.

Acceptance criteria

Derive whether status checks are required from the live branch-protection rule.
Inspect the actual status-context collection instead of relying only on the combined state.
Represent these states distinctly:
- required checks executing or pending;
- required checks failed;
- required checks passed;
- checks not required;
- no checks configured or produced.
Do not classify an empty status-context collection as executing CI merely because the combined state is pending.
Make the derived checks_required value reachable by the production MCP assessment path.
Preserve fail-closed behavior when required checks genuinely exist and are incomplete.
Add regression tests covering:
- empty status collection with combined pending;
- no checks required by protection;
- required checks pending;
- required checks failed;
- required checks successful;
- configured required contexts with no matching result.
Verify the canonical merger workflow receives an accurate recommended_next_action.
Do not weaken approval, current-head, current-base, lease, role-separation, or merge authorization gates.

Constraints

Native MCP workflow only.
No direct API, CLI, browser, database, or credential fallback.
Do not modify or merge PR #750 as part of issue creation.
Do not hand-supply check values merely to make an assessment pass.
Implementation, tests, commit, and PR creation require a separately bounded author task.

Recovery disclosure: implementation at eac7afe5cb was completed and pushed before the issue lock was acquired. The lock was subsequently adopted through the native own-branch path under explicit operator authorization. No code, commit, or branch content was changed during adoption.

Canonical Issue State

STATE: open, implementation complete at eac7afe5cb, issue lock adopted, no pull request created yet
WHO_IS_NEXT: AUTHOR
NEXT_ACTION: Create one pull request from fix/issue-751-checks-assessor into master pinned to exact head eac7afe5cb, citing the adoption proof and disclosing the late lock acquisition.
NEXT_PROMPT:

Create the pull request for Gitea-Tools issue #751 using the native author MCP session bound to prgs-author.
Head branch: fix/issue-751-checks-assessor at exact SHA eac7afe5cbe556b0c83f58ff4bd146b0aaadb3ca.
Base: master at fdab6b6c69717d32a0d50e233413cf09be83f6e8.
Body must include "Closes #751", the implementation and validation summary, and an explicit disclosure that the issue lock was acquired by operator-authorized late own-branch adoption after implementation.
Do not amend, rebase, reset, or force-push the commit. Do not review, approve, or merge. Do not modify pull request 750 or 746.

WHAT_HAPPENED: The issue #751 implementation was authored, committed and pushed before any issue lock existed. gitea_lock_issue then refused the implementation worktree because it was not base-equivalent to master, and gitea_create_pr refused because no lock existed, producing a deadlock. Under explicit operator authorization, a clean recovery worktree was created detached at fdab6b6c69, and the native own-branch adoption path adopted the existing pushed branch. Adoption proof recorded adopted_branch fix/issue-751-checks-assessor, adopted_branch_head eac7afe5cb, competing_branch_check clear, no_existing_pr_proof true, no_competing_live_lock_proof true.
WHY: The lock-before-implementation ordering was violated by the earlier author run. This comment records the real chronology rather than concealing it, so the adopted lock is not mistaken for evidence that the lock preceded the work.
RELATED_PRS: 750 (open, untouched), 746 (open, untouched, advanced independently by another session)
BLOCKERS: no blocker
VALIDATION: Focused suite tests/test_issue_751_checks_assessor.py 40 passed. Pre-existing tests/test_pr_sync_status.py 28 passed unchanged. Affected suites 384 passed with 42 subtests. Full suite 3465 passed, 6 skipped, 2 failed, 365 subtests. The 2 failures were reproduced on a pristine detached worktree at fdab6b6c69 with none of this branch applied and are therefore pre-existing on master. git diff --check clean.

[THREAD STATE LEDGER]

What is true now

Server-side decision state: no pull request exists for issue 751; no review verdict has been recorded; no merge authorization exists.
Local verdict/state: implementation complete at commit eac7afe5cbe556b0c83f58ff4bd146b0aaadb3ca; local head equals remote head; worktree clean; issue lock held by jcwalker3 / prgs-author.
Implementation commit eac7afe5cb was authored and pushed BEFORE any issue lock existed for issue 751. That ordering was incorrect and is recorded here rather than concealed.
Base is fdab6b6c69 and has not moved.

What changed

Issue lock for 751 acquired via the native gitea_lock_issue own-branch adoption path, from a clean base-equivalent recovery worktree detached at fdab6b6c69.
Adoption proof: adopted_branch fix/issue-751-checks-assessor, adopted_branch_head eac7afe5cb, competing_branch_check clear, no_existing_pr_proof true, no_competing_live_lock_proof true.
This disclosure comment was posted.
Zero commit, amend, cherry-pick, rebase, reset, merge, or force-push occurred during recovery. No source file changed.

What is blocked

Blocker classification: no blocker
Nothing currently prevents pull-request creation for issue 751. The earlier deadlock, in which the issue lock was unobtainable after implementation, was resolved by operator-authorized late adoption.
