+-- The breaktimer cache written by bin/breaktimer-sample.sh.
+--
+-- Returns a table describing the daemon, or nil when the cache is absent or
+-- carries no 'generated' key (the sampler never ran). The display strings are
+-- derived here rather than in the widget so the phase-to-word and
+-- phase-to-colour decisions can be tested without Cairo:
+--
+--   { running, state, phase, frozen, remain,
+--     countdown = '24:31' or '--',
+--     phase_label = 'working' | 'micro-pausa' | 'pausa lunga' | 'in pausa'
+--                   | 'outside working hours' | 'fermo',
+--     next = 'pausa' | 'lavoro' | '--',
+--     role = 'ok' | 'heading' | 'highlight' | 'warning' | 'label' }
+--
+-- `frozen` is the sampler's read of whether the clock is ticking: the phase is
+-- 'working' but the remain file has stopped being rewritten. Outside the work
+-- window that is normal and reads as such; a hung daemon looks the same, and
+-- should.
+--
+-- The countdown leads to the next phase, but the daemon keeps the cycle count
+-- in memory and never writes it, so whether the NEXT break is a micro or a long
+-- one is not knowable here. 'pausa' is the honest answer; the phase word carries
+-- the rest.
