agent-deck v1.12.0

A large stability and correctness release: 30 commits, 21 pull requests, and 19 closed issues, with major contributions from the community.

Send & delivery reliability

• Multiline messages now preserve their line structure end-to-end, with delivery verified via scoped paste markers (#1855, #1897).
• The composer will never submit content that is not attributable to the operator (#1777, #1778).
• Canonical delivery verification for sends (#1793, #1831).

SSH & remote sessions

• Remote session identity is location-aware: the same session directory on different hosts no longer collides (#1850–#1854, #1858, #1901).
• Remote sessions can be reordered with shift+up/down (#1875, #1898).
• Remote group headers can collapse (#1874), and descendants of collapsed ancestors stay hidden (#1878, #1899).
• Attaching no longer eats a keypress after session exit, on both local and SSH attach paths (#1783, #1835).

Session lifecycle & status

• Codex completion now converges across CLI polls (#1792, #1896), and hook status is bound to spawn generations (#1825, #1903).
• Durable last-activity records keep timestamps consistent across restarts (#1846, #1847).
• OpenCode sessions preserve launch options on restart (#1843) and no longer leak CLI session polls (#1848, #1849).
• Stale-session output is routed by transcript cwd, not mtime (#1727).
• CLI flags are no longer injected before claude subcommands (#1821).

Watchers & config

• Watcher adapter recovery failures are contained instead of crashing the engine (#1886, #1900).
• Interval hooks get bounded output capture and reliable shutdown kill (#1829, #1845).
• Non-numeric telegram/discord IDs no longer hard-fail config load (#1726).

TUI & web

• tmux client/server protocol version mismatch is treated as alive, not a dead session (#1723).
• Unicode output is preserved for locale-free tmux clients (#1867, #1902).
• Archived sessions no longer leak into the web sidebar (#1844).
• Web link-opening honors a trusted-domains allowlist (#1682).
• Isolated-tree paths honor the IsolateHome marker (#1861).

Toolchain & security

• Go toolchain bumped to 1.25.13 across the repo, clearing four stdlib vulnerabilities flagged by govulncheck (#1895).
• MiniMax model pricing refreshed (#1839).
