Subject: [PATCH] docs(T3): mark nftables fix as applied + accepted
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

T3/A3 completed 2026-10-10: otreca nftables fix deployed via
nixos-rebuild switch. Verification on otreca:
  - nft list ruleset: policy drop + 5 explicit accepts
    (lo, established/related, ICMP, traceroute 33434-33534,
     SSH on tailscale0, Xray REALITY 443) + log+drop
  - iptables empty (no firewall.* shadow rules)
  - SSH via Tailscale: works (the deploy itself proves it)
  - Xray REALITY on 443: listening (sapphira → otreca XHTTP intact)

manifest.json T3 → completed with full notes.
.decisions/index.json T3-A proposal → accepted (status, files
updated to include configurations/vds.nix, notes with verification).

All 17 manifest tasks now resolved (1 truly deferred was T5 backups
risk — formalized as R1.9 in commit 3f5c048, marked completed
2026-10-10). T3 is the last code task — otreca config updated.

Working tree: clean after this commit.
