SSH fetch approval proof — local head 5c1a62e624422d5f865b7196e698723aa6bd1f45
Baseline: main49b0f9683c. Linux x86_64, OpenSSH9.6p1 Ubuntu, Git2.43.
Real GitVcsDriverCore service, NodeServices process spawner, disposable loopback sshd,
confirmation-constrained ssh-agent (ssh-add -c) and disposable SSH_ASKPASS helper.
The helper holds approval, approves after5s, or approves immediately. No desktop GUI,
1Password, FIDO device, macOS, Windows, iOS, Android or Electron desktop verification.
No live user keys/configuration or T3 database used. Before module source is loaded at
its original module URL; after loads actual checkout source. No Git/fetch/SSH mocks.

BEFORE — pending real agent confirmation:
Fixture root /tmp/t3-ssh-approval-proof-6Ovz91; real OpenSSH sshd + confirmation-constrained ssh-agent. No desktop GUI approval claimed.

AFTER — same pending real agent confirmation:

PRESERVATION — GIT_CONFIG hides configured core.sshCommand from preflight:

PRESERVATION — recursive submodule has custom SSH command:
