Added

  • Carrier-down VLAN removal (FR-41). When an owned trunk's physical link stays carrier-down across a two-sample debounce (BOOT_SETTLE_SECONDS apart) - at boot or on the rescan timer - and the box still has a healthy default route, dynavlan removes all owned VLANs on that trunk through the standard validated + health-gated + auto-reverting apply chain. A carrier-down port cannot pass frames, so this is a full teardown of the trunk's set, not a per-VLAN detection diff. Independent of RESET_ON_BOOT: governed solely by new config key REMOVE_ON_CARRIER_LOSS (default true), so a RESET_ON_BOOT=false box still self-heals a dead trunk. Rescan (previously strictly add-only) gains its first removal path; the settle sleep is incurred only when an owned trunk is actually carrier-down, so the steady-state fast path is unchanged. Narrows the prior preservation invariant: preservation now protects only genuine detection uncertainty (carrier-up, no tags) - carrier-down is authoritative kernel evidence and is no longer blanket-preserved. --dry-run previews a would-be teardown; --status reports carrier state per owned trunk.
  • New pure helpers carrier_removals (the debounce decision) and have_routing (the routing pre-condition). have_routing requires a lowest-metric default route, carrier on its egress iface, AND carrier on at least one physical NIC, so a dead trunk that doubles as the box's own uplink with no redundant route is preserved rather than attempted.
  • Public APT repository (GitHub Pages + reprepro): this re-tag republishes v0.4.0 to trigger the new publish-apt CI job for the first time - no dynavlan script change, ver= stays 0.4.0.

Hardware validation (2026-08-04)

All 6 sub-cases PASS on the Protectli box, console-driven: carrier-pull prune (rescan), re-plug re-add, flap-shorter-than-settle preserve, own-uplink-with-no-redundant-route preserve, --boot prune, post-boot re-add. Full detail in dev/features/dynavlan-tests.md (L3-30).
