Cycle 5/6 · wave 55

T27's third trio, the field guide, built silent with invented birds and taps while the owner's questions stay open.

T27's second trio, the hide, built silent with invented birds and taps while the owner's questions stay open.

The first trio from the reopened research: the dawn chorus, built silent, with invented birds and taps, while the owner's questions stay open.

The owner answered 'Do everything', and all three tracks ran at once.

Three new boards after the dinner, and the last trio the enjoyment backlog could give.

Six new boards across two waves, since wave 48 had no APK of its own.

Three new boards for a harvest supper.

Three new boards for a night in the hall.

Three new boards for idle hands.

Three new boards from a washday at dusk.

Three new boards from a washday afternoon.

Three new boards from a lazy Sunday.

Three new boards from a rainy Saturday.

Three new boards from a seaside evening.

Three new boards from the spare room.

Six new boards.

Six new boards.

Four boards that did nothing when tapped on the web version now respond: the milk lanes, the match check, the woodpile rounds and stations on the Chart.

Three new boards from the sorting room.

Three new boards from the packhouse.

No day can crash now.

Three new boards where one fix is not enough and you need two at once.

The Turkish tea board now shows a real Turkish teapot: a steel kettle with a smaller pot of tea on top that darkens from amber-red to near-black as it stews, and the glass under the spout.

Six new boards.

The results card now shows which areas you worked today and where to practise more.

Dances, ironing day and the playroom, three boards each.

Homework and harvest, three boards each.

Washing day came back to the mangle: read a week of loads to say which sock ran and which stayed fast, lay wash windows on a dry and wet calendar so no linen runs out, and walk the green from the well so every web stays wet.

The 3D blocks work again.

Walk-round builds, figure dances and the market.

The morning frame, grading and repair.

Pastimes, the dance floor, and the rest of the projector.

Mending, washing day, and the coffee counter.

Carrying, the senses, and tea and coffee.

Washing day, chopping wood, and the first rooms you can walk round.

The senses, the body's own frame and the hands, in three trios: a plumb line set true inside a leaning stone batter, a tide gauge whose rise the chevrons hide until the stamps make it show, chalk lines ranked by length rather than by look, a bearing pointed from the hour you stand at on a dial that never turns, the one wrong entry in a walk log that came back facing wrong, a marble's pocket forecast before it leaves the spiral, cloths whose corners must meet, bearers under a hinged bar, and a pack that must stay level past the third village.

Optics and photography, across a darkroom, a lens bench and an emulsion tray: splitting a roll when every development step also delivers grain, ordering the night's jobs and the safelight so nothing open meets the wrong light, a pinhole whose smaller hole is softer, a test strip that must answer whatever time is true, slides filed by why more glass will not help, a frame rate and shutter angle that make every wheel tell its own story, a roll developed together after its frames were exposed alone, a paper grade that depends on the burning, and a stereo pair where nothing may touch the frame.

Signals and broadcasting: keying a cable through the printed smear at battery price, ordering relay throws so no intermediate pattern breaks a bearing cap, thinning a printed crowd that interferes with itself, a sky-wave reach that is an annulus so nearness is the obstruction, a propagation window closed from both sides, a phase-blind sampler that must hear the same station from any ten seconds, one crystal in common across every station pair, a mast raise that lifts a knife edge into the grazing band, and the channel that chooses your shadow.

Computing history: Amsler's planimeter (a sign error is a wrong object), punched-card collating, brush-encoder skew, telegraph codes through a one-letter garble, Williams-tube regeneration as a temporal ledger, the polyphase tape ladder read backwards, the self-eroding instruction word, d'Ocagne's nomogram with a tick-limited reader, the add-only worksheet's check plan, time-as-address placement and the printed carriage adversary.

Education and examination: halt-stream against a printed rival, composing for a marking-scheme automaton, Burley's obligationes, buggy-procedure induction, CAT item exposure (the question wears out), Leitner backlog spirals, Angoff borderline inhibition, Scripps elimination cascades.

Money and markets: bottomry inverted seniority, the emit family's first ally-reader, index divisor certificates, Regulation 1103/97 triangulation, tontine ledger reconstruction.

Weather and navigation: oscillation-versus-persistence tacking, TAF-grammar forecasts against a mechanical decoder (silence is a forecast), the altimeter lie, swell-dispersion ranging, monsoon onset protocol design, seiche modes, race-hour scheduling.

Randomizers and machines: the halt-stream verb, Blackwell–Hodges against a modelled guesser, Diaconis–Keller symmetry on the solid stage, Pascal–Fermat 1654, von Neumann unbiasing, kleroterion guarantee design, water-hammer echo pacing.

Performance and information logistics: props tracking, surtitle rate laws, two-reader redaction, Dead Letter Office deixis (the roster's first Grw-RC), travelling post office sorting, quick-change scheduling, counterweight transfers, ventriloquism composition, the one-ahead principle.

The built-environment intake — the Gv repair the catalogue needed: Robbins one-way streets, sky-exposure planes, Bolker–Crapo bracing, Heyman thrust lines, tensegrity, Blondel stair bands.

Law and medicine machinery: triage re-sorting shipped mechanics-first under the register tone gate, Denison conventions, NEAD kidney chains, quorum pincers, cold-chain routing, Snow-style anomaly deduction with abstract-map copy.

Twelve modelled-reader, regime, rulebook and convention types — referee_reads (the FIE priority automaton) is the emitted flagship.

Twenty-four types, twelve of them the first builds from the Cycle 5 addendum: karuta kimariji, block-bell protocol, SECDED, Arom rhythmic oddity, the Dresden Codex Venus table, Wang Zhen typecase, Burnside counting, DRM false memory.

Twenty-five more types across reckoning (Maya and Egyptian numerals), world board games, reshuffle-shutter working memory, executive function, metacognition, solid bodies, rotation and silent phonology.

The first build wave: 17 new types, all of catalogue wave 1, from eight builders in isolated worktrees merged by a keep-both resolver.

The instrument is inhabited.

Phosphor v2 DEPTH: the bevel system, Key.tsx with 2px travel, perspective flips.

The identity cycle.

Engine integrity overhaul shipped as the first installable build: 5 of 16 types had no validator (~44% of days unwinnable), wrong answer keys, unsolvable word ladders and an invalid 6×6 sudoku generator were found and fixed.
