Added Race 2: tailscaled starts before network-online.target, causing
Tailscale to get stuck with SetNetworkUp(false). Covers both Ubuntu
ssh.socket and cross-platform tailscaled ordering issues. Updated
references to include majordiscord incident and new Ansible playbook.
Documents the systemd socket activation race where ssh.socket binds
to the Tailscale IP before tailscaled is ready, causing SSH to become
unreachable after a Tailscale reconnect. Includes diagnosis steps and
the After=/BindsTo= fix.

Two articles surfaced during the v8 deploy + eval on 2026-04-25:
- Ollama: `ollama run` with piped stdin bypasses the chat template and
SYSTEM prompt — output looks like raw base-model completion. Caught
during initial v8 smoke test. Fix: use /api/chat HTTP endpoint.
- rsync over Tailscale can hang in TCP teardown after the data has
fully transferred. Verify with md5sum, then kill the hung pipeline.
Includes a watcher-threshold gotcha (set below true file size, not
above) and prevention tips.

5 files had stale unmerged index entries from a prior aborted merge —
working tree was already clean (no conflict markers), differences were
purely `updated:` field timestamps that drifted across machines via
Obsidian Sync. Working-tree timestamps (most recent) are kept as the
resolution.
Sixth file (mastodon-instance-tuning.md) preserves staged S3 cache
management content that a working-tree revert would have lost.

by the postfix-sasl jail after repeated SASL auth failures, silently
blocking all IMAP connections from Spark Desktop.
