Summary
Map known Gitea authentication failures (HTTP 401 / revoked-invalid tokens) to sanitized structured MCP tool errors (
CallToolResultwithisError=true) so stdio transport survives and clients never observe EOF for recoverable auth-class defects.Closes #699
Linked issue scope (strict)
Implements only #699. Does not absorb:

b4d0cb22e4Formal verdict: none submitted. The review found request-changes-class security/framework defects, but native reviewer lease state was lost and the formal-review gate now prohibits submission.
Findings
gitea_auth.py:456-464copies HTTP error bodies into exceptions, whilemcp_tool_error_boundary.py:46-67can return raw text and does not remove arbitrary secrets;:215-229can log them. Adversarial checks reproduced response-body, Keychain-content, and daemon-log leakage.mcp_tool_error_boundary.py:277-309replaces FastMCPTool.runand catches all exceptions. A real stdio subprocess proved auth-error transport survival but also proved the wrapper swallows SDKUrlElicitationRequiredErrorand returnsinternal_error, breaking framework/unrelated-tool semantics.mcp_tool_error_boundary.py:129-160classifies arbitrary RuntimeErrors by message substring;:256-261calls every RuntimeError a known client failure. An unexpected parser RuntimeError was reproduced as authentication.gitea_auth.py:313-333and becomesinternal_error, so 403 is not reliably distinct from unexpected internal failure.Canonical Issue State
STATE:
review-blocked; no formal verdict; request-changes-class defects reproduced
WHO_IS_NEXT:
controller
NEXT_ACTION:
Reconcile or canonically expire the active reviewer lease and repair the reviewer worktree binding; then author fixes the four findings and a fresh independent reviewer reruns the complete workflow at the new pinned head.
NEXT_PROMPT:
WHAT_HAPPENED:
Independent review used a fresh detached branches worktree at the exact pinned head. Focused and related suites passed, but three adversarial checks failed. During validation the MCP workflow proof and in-session lease disappeared; safe reload found the durable lease active but session_lease null and classified it foreign_active_current_head with exact next action wait.
WHY:
The implementation exposes secrets, changes unrelated FastMCP framework behavior, and can misclassify unexpected RuntimeErrors. Native controls also forbid transferring validation or decision state across the lost lease, so no formal review bypass was attempted.
RELATED_PRS:
PR #701 only. PR #696 was not reviewed, launched, or mutated.
BLOCKERS:
Code blockers: secret leakage; swallowed URL elicitation; RuntimeError misclassification; generic 403 internal misclassification. Workflow blocker: lease 11131 is active but absent in-session, environment/proposed worktree binding disagrees, mutation_eligibility=prohibited. UNBLOCK CONDITION: controller-authorized lease expiry/reconciliation and matching reviewer worktree binding, author remediation at a new head, then a complete fresh native review.
VALIDATION:
39 focused tests passed; 165 related config/MCP/provenance guards passed. Real stdio subprocess failed only after proving auth structured error + subsequent-call survival because URL elicitation became internal_error. Adversarial redaction failed for response-body/Keychain/log secrets. RuntimeError adversarial classification failed. Full suite was not run after the mandatory workflow hard-stop. Worktree and root checkout remained clean; no source edits, commits, pushes, merges, direct APIs, offline helpers, or formal review mutations.

NEXT_ACTION:
Wait for lease 65664-4f248d213d60 to canonically expire. The human operator will then clear the stale
GITEA_ACTIVE_WORKTREEbinding. The author must then remediate the ratified defects at a new head.NEXT_PROMPT:
WHAT_HAPPENED:
Controller ratified the four findings from the aborted review session. No formal verdict was submitted because the native reviewer lease state was lost due to an unhandled exception crashing the daemon. A durable issue (#702) was filed to track the lease/workspace-binding defect.
WHY:
The implementation exposes secrets, changes unrelated FastMCP framework behavior, and misclassifies unexpected RuntimeErrors. These are controller-ratified blockers.

Author remediation is required for the four findings. The reviewer namespace environment variable
GITEA_ACTIVE_WORKTREEmust be manually cleared by the operator before the next independent review.VALIDATION:

CTH: Controller Decision — #701 review resume vs #704
Status: #704_not_a_merge_or_review_gate_for_#701; resume_still_follows_#702_#703_and_clean_runtime
Next owner: controller
Current blocker: unchanged by #704 — still the #702/#703 recovery track and prior #701 review discipline (fresh lease/worktree at head 6b675f5…), not dotenv-guard merge
Decision: Issue #704 does not need to merge before PR #701 review can safely resume. Safe resume requires (1) neutral workspace binding (operationally restored per #702 comment 11191 / PR #703 comment 11193), and (2) durable #702 recovery via PR #703 formal review/land per prior CTHs. #704 is immediate follow-up hardening against repository
.envre-injection and is out of band for #701 formal review. Full matrix: Issue #704 comment 11202.Proof: #702 ACs; #704 dependency CTH 11202; comments 11191/11193; this PR still implements #699 only.
Next action: Do not wait on #704 for #701; continue #703 formal review, then resume #701 with fresh leased reviewer at live head.
