Baixar ArWen 2.6.1 per a Windows

Continuous assimilation gets a door, agents get a protocol, and the
sub-kilometre unlock is finished.
New:
- gpuwm cycle: continuous radar assimilation as a door. A cycle clock
schedules analyses, a ledger records every cycle's inputs and verdicts,
a supervisor drives the fetch, assimilation and forecast legs, and
anchored child domains follow the feature being cycled.
- An MCP server: arwen-mcp serves the CLI doors as tools over stdio, so
an LLM agent can plan, price, fetch, prep, forecast and render. Every
tool runs the real command line or reads a receipt a door already
wrote; refusals arrive as the CLI's own sentences. Long work runs as
detached jobs that survive a server restart, one GPU job at a time per
card. pip install gpuwm[mcp].
- The MPAS column-batch seam carries P3: microphysics_scheme = "p3"
transports the scheme's eight species through both phases beside the
unchanged WSM6 default, and a restored P3 seam continues
bit-identically.
- Sub-kilometre static builds: below a 1,310 m source-pixel diagonal the
static builder now derives categorical fields by supersampling, keyed
to each mesh's measured minimum edge, where it used to refuse.
Demonstrated end to end with a 937.5 m mesh generated, built, and run.
- Level-2 regional spectral numerics: an optional [spectral_numerics]
table runs scale-selective hyperdiffusion and divergent-mode damping in
off (bitwise inert, the default), shadow (receipts only), and
apply modes, with per-step receipts bound into the run capsule and a
gpuwm spectral-op evidence door. A research instrument, not endorsed
physics.
- Nowcast skill is scored against an operational baseline, with structure
metrics beside the existing point verification.
- Windowed all-radar ingest: assimilation cost follows the sites in the
active window, not the domain, and successive nest windows hand their
interior over during the overlap instead of restarting cold.
- Nineteen measured sizing configurations for ensemble, reanalysis and
AI-model sources the configuration set had not covered.
Fixed:
- gpuwm prep no longer grows its host memory with the length of the
forcing window: the mapped engine decodes one valid time and drops it
before asking for the next, and the identity pass admits objects under
a bounded byte budget. An ICON-EU preparation peaks at 2.32 GiB at
both a 3 h and a 6 h window, frames byte-identical; compressed
field-per-file sources still pay a modest wall premium for the
per-time discipline, and that remainder is named work.
- gpuwm check on a nested tree with [tiles] prices the mixed road
the run door actually takes (child streamed, parent resident) instead
of refusing trees that fit; the report names each domain's road and
--json publishes it.
- A [tiles] configuration the loader refuses reaches the terminal as a
refusal with its remedy intact, on every door, instead of a traceback.
- A restored MPAS column-batch seam no longer refuses its first
radiation-not-due step: the restart payload carries radiation carrier
provenance, and the seam's device round-trip gate runs at every cut.
- P3 no longer computes NaN supersaturation ratios on its first step:
the cold-start saturation mixing ratios are floored, default-on in all
three arms, inert from step 2 onward, with the one step-1 delta
documented.
- mp=50 composes with RTE+RRTMGP radiation: the adapter couples P3's own
two-radius cloud optics, matching the scheme's own inventory, and the
refusal that outlived the gap is retired.
- A wrong-version P3 lookup table is refused as a version mismatch
instead of being reported as byte corruption, and gpuwm doctor
checks the table.
- Velocity dealiasing uses each radial's own Nyquist velocity; the
reader detected per-radial disagreement and then dealiased against one
scalar anyway.
- A radar with no innovations no longer reports the whole network's
residual as its own, and the continuous nowcast daemon no longer
crashes at the first observation stage of every cycle.
- Data assimilation reads P3's own 10 cm reflectivity instead of
refusing an mp=50 background, and clear-air reflectivity carries one
floor value instead of two.
- A cycling analysis takes the card by default when one is reachable
(auto); host and cuda stay honoured verbatim and every receipt
records which device ran and why.
- The P3 oracle suite now fails when physical processes are switched
off; the previous fixture set stayed green with five disabled.
- Mesh generation receipts print small trace values in scientific
notation, and the ladder's location check credits grading and
insertion instead of refusing meshes it graded correctly seconds
earlier.
