M1 guard: secure-file's openFileBeneathRoot no longer refuses every symlink component. The lexical path must still name the managed root; symlinks are then resolved hop-by-hop, each hop validated (containment under the root or a caller-sanctioned additional root such as the brain home on split-home layouts, current-user ownership, no group/world-write mode, bounded chain depth), and the O_NOFOLLOW descriptor traversal walks the symlink-free real path — substitution races after resolution still refuse. Framework-created layouts that now pass: the roster symlink config->brain, and rebound-HOME config roots. Escaping, foreign-owned, loose-mode, and over-deep targets still refuse. M2 resolver: resolveFleetIdentity no longer hardcodes <mosaicHome>/tools/tmux/agent-send.sh. The helper is probed across the framework install homes (mosaicHome, MOSAIC_HOME, default config home), so a brain-shaped mosaicHome (~/.mosaic, no tools tree) resolves the helper from the framework config home. M5a: error text no longer recommends the forbidden 'mosaic update --repair-tools' remedy; guidance names the actual recovery shape. Verification unblock: parseFleetRosterV1 tolerates the roster-v2 envelope the fleet's own mutation tooling writes (version 2, top-level generation fence, defaults.runtime, agent model/reasoning and lifecycle/launch sub-objects) — validated, opaque to comms semantics. Without this the #1380 member-positive-control cannot pass on the live roster. Tests: resolve-then-validate arms (valid in-root symlink ancestor and file, split-home sanctioned root, escaping refusal, group-writable refusal, foreign-ownership refusal via the afterStat race hook, race substitution arms unchanged green); resolver arms positional with nonce and no-name controls per the #1380 protocol, helper-not-found names every searched home; v2-envelope arms; reseed refusal diagnostics updated. 405 fleet/reseed tests green; typecheck, lint, format clean. Host-layout verification (read-only, local): 7/7 protocol arms green — orch-01 member positive control through the roster symlink under both homes, nonce/no-name controls, jarvis non-member names membership, and the launcher resolver entry composes the contract.
