Card 56 took a phase's members off the Board; this is where they went. A fourth view beside Board, Sessions and Focus, holding one lane per phase card — every phase there is, not only the running ones, because a phase whose cards are all merged and which is waiting on its own PR still owns them.
A lane is a head, five stage columns and the phase's log. The head carries the phase, its progress, the member in flight and its own controls — hold, the phase branch, the phase card — and nothing that ends a phase, which stays a board move on the phase card. Four columns are the board's stages; the fifth is 'Merged in', not done/, because a member merged into the phase branch is finished as far as the phase is concerned and is not in main yet. Which members the branch holds is the runner's last pass while a phase runs, and the phase log once there are no more passes, so a phase in review/ still draws the work where it landed. The cards are the cards: cardFor() builds them here exactly as it builds them for the Board, agent line, chips, position-in-the-run chip and hover actions intact. The phase log sits under the lane, the runner's decisions in the order it made them, read off the card's own '## Phase log' — the only thing that can tell "not reached yet" from "started and ended badly".
A halted lane says so at the top of itself, names the card it stopped on, and offers run again beneath the reason. That action left the Board's phase card for the same reason: clearing a halt should mean having read what caused it, so the card offers a way into the view instead, and hold, which needs nothing read. The crossing the other way is the switcher, which carries how many phases are running and an alarm mark while one has halted — on every view, alongside the toast and the ticker line that already fire.
Covered by tests/test_phases_view.py: collect() reads a throwaway tasks/ tree and the page's own lane rules run over that reading in node (ordering, placement, the last column, the log, the all-merged phase in review/), plus source-level wiring invariants for the DOM half. test_phase_watch, test_card_actions and test_scroll_kept updated where this moves what they pin. Full suite green: 939 tests.
