…-out decisions as .t27 (Closes #11059) A tick of the overnight loop was prose in a skill, so a new cron cycle could repeat or undo the last one. specs/tri/loop/tick.t27 now holds those rules as pure functions over a line-oriented snapshot (now, last, row, want, pr, merged, agent, cron, req), with 25 tests: - a lane the ledger lists (any state) is never started again; a `want` with no row is START, once; - a row that says running for 45 whole minutes or more is RECHECK (the number is lanes.t27's STALE_MINUTES, imported; a test holds the two equal); - a red pull request is FIX, a conflicting (DIRTY) or behind one is UPDATE_BRANCH; no action is a force-push; - a subagent done with no pr or merged record for its branch is FIND_PR; - a later cron with the same prompt is DELETE_DUPLICATE; - a request is NONE before due, CHASE once when open and due, TAKE_DEFAULT when chased and due, never CHASE when chased; - an unreadable record, a time that does not parse, a second now, last or request id is UNREADABLE, never silence; - the tick ends with HASH n over the records and their plan (not now, not last); a snapshot whose `last` equals it is NOOP, and a lane crossing 45 minutes changes the plan, so time passing is a change. `tri loop plan [FILE]` reads the snapshot from FILE or stdin and prints one `ACTION key reason` line per action. It runs no command and contacts no network or machine. The glue sits in cli/tri/src/loopclaim.rs (23 added hand lines, through t27c gen-rust in gen/rust/tri/loop/tick.rs); the tool card of `tri loop` lists the new action. The 23 lines are paid for by deleting 40: the unused `delete_railway_service` in bootstrap/src/railway.rs (git grep -w finds no other mention). Searched first: tri night, tri lanes (its time readers and STALE_MINUTES are reused), tri worktrees --reap-plan, specs/claw/refresh.t27, specs/queen/review_valve.t27, specs/queen/waits.t27, specs/tri/reseal; none decides a tick's actions from a ledger.
