Problem
Gitea MCP servers can report Connected at the CLI / host inventory layer while the active LLM session exposes none of their tool namespaces. Native workflow tools are therefore unavailable until an interactive
/mcpreconnect attaches the namespaces to the session.This is a session-attachment failure, not a missing config entry, not a transport-closed error, and not a stale-runtime self-kill path. The host believes the servers are healthy; the agent session still cannot call
gitea-author/gitea-merger/gitea-reviewer/gitea-reconciler/gitea-toolsuntil the operator performs a manual reconnect.Failure signature
/mcpreconnect (operator babysitting)Distinction from related issues
This issue is not a duplicate of the following; keep them separate:
gitea_resolve_task_capabilitystale path touches config +os._exit, causing client EOFDo not collapse this into config-drift, reconnect-exposure, resolver side-effects, or transport-closed trackers without explicit operator approval and evidence that the root causes are identical.
Impact
/mcpreconnect, re-run identity/capability preflight.Recurrence evidence (blocked PR #696 merger session)
PR #696 (
feat(guard): native MCP transport binding and contaminated-review quarantine (Closes #695)) is linked only as the observed blocked task, not as the implementation target of this issue.During a merger session targeting merged PR #696:
/mcpreconnect.PR #696 itself implements #695 (native transport binding / contaminated-review quarantine) and is merged. This issue tracks the session attachment / discovery defect that blocked that merger workflow class — it does not reopen #695 or re-implement #696.
Investigation requirements
Investigate and document (with tests where possible) the full client attachment lifecycle:

NEXT_ACTION:
Fresh leased native reviewer session reviews PR #703 at its live head against issue #702 AC2/AC3. PR #701 requires a separate fresh native review before any merge consideration.
NEXT_PROMPT:
WHAT_HAPPENED:
Post-restart recurrence check on Issue #708: gitea_quarantine_contaminated_review attached to client discovery after reconnect plus client-side tool rediscovery; no further restart was needed. Reviews 427 (PR #694) and 431 (PR #701) were then quarantined through the native production transport, and readback proves both APPROVE verdicts are void for merge authorization while forensic evidence is retained.
WHY:
Both reviews were produced by non-native execution paths documented in issue #695 (offline-runner bypass for 427; run_submit.py direct-import with redirected .mcp_session_701 session-state directory for 431). Per #695 AC8 such verdicts are void and require durable quarantine records that the feedback, eligibility, and merge gates honor by review_id.
RELATED_PRS:
PR #694 (open state, review 427 quarantined), PR #701 (open state, unreviewed for merge purposes, review 431 quarantined), PR #703 (awaiting fresh reviewer).
BLOCKERS:

The #708 defect is that a host reporting Connected does not prove the role tool namespaces are attached to the active session. The prior slice detected that condition but nothing consumed the verdict, so native workflows could still mutate while unattached. Wiring the verdict into the session store and the review and merge gates is what makes the fail-closed behaviour real.

Required-but-not-connected namespaces are now counted distinctly and typed mcp_required_namespaces_not_connected; mcp_connected_namespaces_missing is reserved for genuinely Connected namespaces; attachment_healthy is false whenever any required namespace lacks attachment proof; per-namespace conditions drive the session store; and the gate states only what the recorded evidence supports rather than asserting a Connected host.58bd852188corrected B1: the anchors fixture and the threat-model document named different source revisions.

An author session on the prgs-author namespace resumed the exact-head change request from review 637 and corrected both blockers in two commits on the existing branch, then pushed, updated the PR description to match the results actually obtained, and handed back for independent review.
WHY:
Review 637 required the document and the fixture to agree on the actual generation revision, and required not-connected to stop borrowing the Connected-but-unattached condition and its recovery, which #708 forbids collapsing into #672 or #584. Both were corrected at the source rather than by editing a string to satisfy one assertion: the generation contract was re-verified end to end, and the classification change carries a new focused regression file.

An earlier ledger entry and PR description stated that

Accepted serial comparison
17ba1ff035ee58bd8521Failing identifier sets are identical. No head-only failure requires classification. The B1 threat-model regression is absent at the head.
Follow-up issue material: concurrent full suites are unreliable in this repository
Recorded here as follow-up issue material only. No fix is attempted in PR #967, and no test-harness file, service, or configuration was touched.
An earlier attempt ran the head and base full suites concurrently and produced head 40 failed / 5898 passed against base 31 failed / 5861 passed, with the head run finishing in 178s against the base run's 512s. Those figures were discarded in favour of the serial runs above.
The cause is shared mutable state outside the worktree, not anything in this branch. Two suites running at once contend over the same pinned session-state directory (
GITEA_MCP_SESSION_STATE_DIR, default~/.cache/gitea-tools/session-state) and the same control-plane SQLite database. Neither is isolated by running each suite from its ownbranches/checkout, so lock, lease, session and decision records written by one run are visible to the other and produce failures that neither revision causes. A future issue should give each run its own session-state directory and control-plane database, or make the harness refuse to start while another run holds them.What is true now:
