Carries the seven security fixes up from the maintenance line. Master has been refactored underneath most of the code they touch, so this merge lands only the part that applies as written; the rest is re-implemented against master's architecture in the commits that follow. Landed complete by this merge: - Bound the coordinate-cache warm path by the encrypted-header parser. The guard applies unchanged in src/node/dataplane/forwarding.rs, which is where master keeps the warm path. Its test is not here: master and the maintenance line added different tests to the same region of src/node/tests/forwarding.rs, and the union is made with the test that belongs to it. - Filter and cap the punch targets taken from a peer's traversal signal. - Reject traversal signals dated in the future. - The character-boundary fix to the session-id log helper, which is what made the two traversal fixes safe to log. Deferred to follow-on commits, because the mechanism they change does not exist upstream in the shape the fix was written against: - Bound a remote-supplied path MTU, and give the cache a way back. Master routes the keep-tighter rule through a sans-IO core with an apply site the maintenance line does not have, and keeps the lookup handlers in src/node/handlers/lookup.rs rather than a discovery module. The floor constant, the release helper and the TUN clamp side are here; the apply sites are not. - Act on a routing signal only for a destination this node has bound. - Never destroy an established session on an unauthenticated setup message. Master decides rekey in a clock-free core off a snapshot, so the fix's condition has no loop to sit in. - Let flap dampening engage again after an episode lapses. Master extracted the mechanism into a component with an injected clock. The counters, statistics and status-pane fields for the deferred fixes merged cleanly and are in this commit, so they read zero until the fix that feeds them lands. The halves that would not compile or would fail without their fix were held back with it. Green at this tree: fmt, build, clippy --all-targets -D warnings and test --lib at 1784 passed.
Reference
Information-oriented technical descriptions for lookup on demand. Reference content describes what is: wire formats, configuration keys, command-line flags, control-socket commands, default values, file paths, exit codes. It is consulted, not read end-to-end.
Reference is austere by design: minimal narrative, no opinions, no guidance on when to use a feature. The "why" lives in design/; the "how do I accomplish X" lives in how-to/.
