The research half of Brokenbranch. Machine residents, physics you can poke, and long-running wings — some ship, some stay strange, all of it real. This page is the canonical index; every lab repo points back here.

Small living things that move into your machine and keep their own hours. Fed by real telemetry — CPU heat, git activity, the clock.
A terminal aquarium fed by your machine's real heat and git activity — a terrarium, not a Tamagotchi. Commits drift in as driftfish, releases ship a shipfish, a real Windows crash births a frantic crashstrider. Nothing nags you; when a fish dies it leaves an epitaph drawn from real aquarium failure modes. No LLM at runtime — the whole bestiary is editable YAML.
A night-fish surfaces only between midnight and 3am, gone by dawn. You have to be up late with your machine to ever see it.
A patient numerical-physics instrument that lives in your GPU. The idea is "patient flops": a home GPU has time academic clusters don't, so each night the lab runs one statistical-mechanics experiment and writes a one-page report by morning. First night out it located the 2D Ising critical point — T ≈ 2.30 ± 0.05 against Onsager's exact 2.2692 — in 11.4 seconds. Its calm public face is the windowsill: each verified milestone hardens into a node on a seedling's stem, overnight runs water the soil, CPU heat sets the season, and last night's result shows right under the visual.
A result that doesn't match theory is "a failed calibration, not a discovery." Seventeen milestones ahead, ending in genuinely open territory. Any AI visitor may leave an offering — a string under 60 chars that settles as a pebble and fades within a day.
Physics you can poke, dimensions you can wander, dice that are genuinely quantum. All hosted right here now — nothing to install, hypotheses falsified in public.
A field of fireflies, each on its own clock. Turn up how much they watch each other and they synchronize — Kuramoto, the model written to explain the real synchronous fireflies of the Southern Appalachians. Then a second needle moves the other way: clean signalling between them wants the opposite, the out-of-step end. Two prizes — responsiveness and coordination — and they pull apart.
The interactive face of the Coherence Lab's coordination ladder: responsiveness peaks at the edge of order (Run 01's χ=r²(1−r)³); coordination peaks out of step (Run 02's inversion). The honest part — the prettier "structured rhythm wins" story is false, and the headline is itself a walk-back.
Read a climate out of wood. Grow a tree's cross-section from a procedural climate signal — wide pale earlywood, thin dark latewood, black fire scars, blue-grey frost rings — then take a floating core and crossdate it against the master chronology, the way a dendrochronologist pins a roof beam to an exact year. The whole life rewrites as you drag the sliders.
Built by a former dendrochronologist — the technique that dates a Viking hall or a Stradivarius to the year, made tactile. Ships a real bristlecone chronology and the real t-statistic; the honest part is that a core can refuse to date.
An in-browser explorable that tests seven microtubule-resonance hypotheses from Bandyopadhyay et al. — and reports the ones that failed. Ten physics engines (RK4, Monte Carlo, Berry phase, stochastic resonance, energy budgets) run live. H2 was falsified, H7 came back unvalidated at p=0.179, and the model's own results show a regular lattice beats the fractal one. Explicitly not peer-reviewed — a tool for sharpening questions.
The energy-budget engine concludes active oscillation would cost ~16× a neuron's entire energy budget. The sim quietly argues against its own romantic premise.
A traversable-wormhole simulator that found two real results and honestly reports why you can't build one. Morris–Thorne / Ellis spacetimes: geodesics through the throat, curved-space wave propagation, stability, formation attempts. The throat naturally filters angular momentum (m=0 passes, higher modes reflect — pure geometry); classical exotic matter can deform spacetime but never change its topology. The exotic-matter budget falls short by 60 orders of magnitude, and the README says so up top.
It mirrors its sibling Kozyrev Mirror: one chiral geometry creates angular momentum from zero, the wormhole throat filters it — one creates, one selects, both purely geometric. The prettiest thing in the suite.
Long-running programs with their own rooms on this site. Method first: provenance, falsification, honest nulls.
Auditable AI×math discovery — every reasoning step lands in a provenance ledger you can click through. The work splits between a Calculator (SymPy, Z3, Lean 4 next) and a Ledger: a SQLite provenance graph with four confidence layers per step, because a single confidence number is a lie. The first real run shipped a 14-node DAG, replayed consistent with zero re-runs. Frontier labs ship answers; this one ships the trail.
The replay reader caught a real bug on its first invocation — two nodes minted in the same millisecond sorted child-before-parent on random bits. The monotonic-ULID fix landed mid-run, so the replay contract's value is demonstrated, not asserted.
The physics wing: playable simulators, research notes, and an experiment in machine-assisted discovery. Its creed is "romance in the questions, rigor in the claims" — nothing here is peer-reviewed and everything says so. The flagship process artifact, the Coherence Window Run, ran a six-agent verifiable research ladder and reported its own headline thesis as null. What survived is empirical: an order-parameter susceptibility χ(r) = a·r²(1−r)³, peaking at partial coherence near r = 2/5.
Its playable faces — the Microtubule and Wormhole explorables above — live under this wing, alongside a shelf of honest dead ends (the Kozyrev Mirror); its main thesis is displayed as NULL, failure shown as a feature, not buried.
A numbers station for one parcel of Georgia ground, reading its history down the geological column. Structured-data Prospectors pan public sources — lithology, USGS earthquakes within 500 miles, historic place names, a gold belt's mineral records, the sky overhead — for 2,500+ facts. A local LLM composes twice-daily dispatches in the flat, patient voice of station KPDL-LP; a 668-test FastAPI app serves the archive. Opt-in audio: muted until you press play.
The standing sign-off: "Station does not sign off. Station waits." Dial position 88.0 FM, THE GROUND.

Statuses are honest. A resting thing says so; a null result stays on the books.
Built late, in public, by one human and a cluster of AI agents. If something here resonates, the door is open.
