`multiply_with_allocation` branched on `generic()`, but the two arms were the same computation: `multiply_qpart(m1, 0)` returns `[(1, m1)]`, so the classical arm is the generic one with an empty exterior part. Collapse them into `milnor_product`, a free function that reports each `(coefficient, basis element)` through a callback, leaving the index lookup and excess filter to the caller. `multiply_qpart` becomes free too; it only ever read the prime. `generic` was a `bool` field written once as `p != 2` and never mutated. Derive it instead. That also drops its `#[cfg(feature = "odd-primes")]` gate: without the feature `ValidPrime` is the zero-sized type 2, so the comparison folds to a constant on its own.

Inline comments:
In `@ext/crates/algebra/src/algebra/motivic/ctau.rs`:
- Around line 297-300: Replace the debug-only assertion in
decompose_basis_element with an unconditional hard assertion so nonzero
residuals and generator indices always fail in release builds; preserve the
existing zero check and diagnostic message.
- Line 160: Bound the parsed Q_ index before shifting q_part in the relevant
parser, rejecting indices 32 or greater instead of performing an out-of-range
shift; use checked shift behavior so failure propagates as malformed-input
rejection. Extend test_ctau_basis_element_from_string_round_trips with a Q_32
case that verifies rejection without panic.
- Line 133: Update the basis-product flow around milnor_product to pass a
reusable PPartAllocation through PPartAllocation::with_local, returning the
allocation from milnor_product so with_local can restore it for the next product
instead of creating PPartAllocation::default() each time.
- Around line 136-138: Update the index lookup in the product-term handling
around ac.index_of within enum_basis so a missing degree-t monomial is surfaced
as an invariant failure via expect rather than silently skipped; preserve the
existing result.add_basis_element call for valid lookups.
In `@ext/examples/resolve_motivic_ctau.rs`:
- Around line 39-46: Update the example to call the public
MotivicResolution::trivial_module helper instead of manually constructing
CTauAlgebra, FDModule, and BiVec, and replace the explicit FiniteChainComplex
type with the public CTauResolution alias. Preserve the existing Arc-wrapped
chain-complex construction and downstream behavior.
In `@ext/src/motivic/mod.rs`:
- Around line 187-190: Change the public MotivicResolution constructors
with_module and new to return anyhow::Result<Self>, propagate
Resolution::new_with_save failures with ?, and remove the expect-based panic
while preserving successful construction behavior.
- Around line 706-715: Update the non-convergence handling in lift_cell and its
solve → None path so exhaustion of the iteration cap is surfaced as a genuine
failure rather than logged at debug level and returned as a silently partial
differential. Preserve normal successful convergence and use the existing
error-propagation mechanism from lift_generator to solve.
- Around line 206-210: Clamp the parsed MOT_MARGIN value to a minimum of 1
before constructing the compute box in the Bidegree::n_s call, preserving the
existing fallback for missing or invalid values so compute.n() never falls below
max.n().
- Around line 466-467: Update compute_weights to seed a weight for every
generator with s = 0 instead of only Gen { s: 0, t: 0, idx: 0 }. Derive each
cell’s weight from the caller-provided module data, or have with_module reject
modules whose s = 0 cells lack determinable weights; ensure downstream methods
such as lift_generator, delta, mod_tau_support, and entry_weight never encounter
unseeded generators.
- Line 532: In the power calculation near the motivic cell construction,
validate that self.weights[&gj] - w_k is at least 1 before converting it to u32.
Update the code around the power binding so negative differences fail
immediately, preserving the existing positive-power behavior and allowing the
test guard to detect inverted weights.
In `@ext/src/motivic/persist.rs`:
- Line 70: Add a round-trip test covering Mot ivicResolution lift-cache
persistence: resolve a small box with a temporary save directory, rebuild from
that directory, assert load_lift returns true and the reloaded weights and
lifted values match the original results, then verify a different max rejects
the cached data.
- Line 65: Update ext/src/motivic/persist.rs at lines 65-65 to explicitly flush
the save writer and log any error at warn level; at lines 29-31, handle
File::create errors by logging the path and error before returning; and at lines
131-131, distinguish Ok(None) from Err(e), logging the load error at warn level
while returning false in both cases.
- Around line 34-43: Update the motivic lift persistence handled by
MotiviсResolution::with_module, Resolution::new_with_save, and load_lift to
store a stable module/algebra fingerprint in motivic-lift.bin alongside the
existing dimensions, then validate it during loading and reject caches whose
fingerprint differs, even when magic and (max, compute) match.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
The non-convergence justification does not hold at the only call site.
lift_generator (Lines 345-346) calls lift_cell only when in_cone is true. Every lift_cell invocation is therefore an in-cone cell, and this comment states that in-cone cells converge. If the loop exhausts the 256-iteration cap, the code's own reasoning says a real invariant failed, yet the result is a debug! log and a silently partial differential. The solve → None path at Lines 693-695 carries the same stale "out of range" justification.
Promote the outcome so a genuine failure is visible.

Include a stable module identity in motivic-lift.bin. MotivicResolution::with_module accepts any module and save directory. Resolution::new_with_save validates cache dimensions only, not module actions. load_lift accepts a cache when only the magic and (max, compute) match, so two same-sized modules can reuse one cache and produce incorrect lifted differentials. Store a stable module/algebra fingerprint and reject mismatches.

Every cache I/O error in persist.rs is discarded. The save path and the load path both swallow io::Error, so a user who passes save_dir gets no diagnostic when the directory is unwritable, the disk is full, or motivic-lift.bin is corrupt. The program silently recomputes the lift on every run. The shared remediation is to log each error at warn level.

Add a round-trip test for the lift cache.
No test passes a save_dir to MotivicResolution::with_module, so save_lift and load_lift are entirely uncovered. The failure mode of this code is silently wrong results rather than a crash, which makes the gap material.
Add a test that resolves a small box into a temporary directory, rebuilds from the same directory, and asserts three things: load_lift returns true, the reloaded weights and lifted equal the freshly computed ones, and a run with a different max rejects the cache.

Carve the motivic resolution layer out of the integration branch as the next tranche after the algebra engine (SpectralSequences#266, merged). Adds CTauAlgebra, the A_C/tau view the ordinary resolution engine resolves, and MotivicResolution: resolve the trivial module over A_C/tau, then lift the differential to A_C by correcting along the weight grading. Includes the resolution cache and the resolve_motivic_ctau example. A_C/tau is F_2[xi_i] tensor E(tau_i) — the odd-primary dual's shape with 2^i for p^i — so its product is the classical one at p = 2: the exterior commutation shifts by 2^k and the signs collapse over F_2. It therefore multiplies through `milnor_product` from the parent commit rather than reimplementing the walk, and a test cross-checks that against the engine's independent closed-form product, which comes from Kong-Lin duality instead. Note that `milnor_product` takes its left factor first while the engine's `product_indexed` orders its arguments the other way; the two agree exactly under that transposition.

Parsing and product invariants in CTauAlgebra: - `Q_k` with k >= 32 was shifted into a 32-bit exterior mask: a debug panic, and in release a masked shift that silently produced the wrong monomial. Module descriptors are untrusted input, so reject it instead. - A product term absent from the degree-t basis was skipped. `enum_basis` holds every such monomial, so a miss is a broken invariant, not a term to drop; say so. - Reuse the `PPartAllocation` across basis products rather than allocating one per call. - The decomposition residual check guarded a silently wrong result, so it now holds in release too. In the resolution: - `MOT_MARGIN` below 1 shrank the compute box under the report box, so readers indexed generators the lift never populated. Clamp it. - The tau-power cast wrapped a negative difference to near u32::MAX, which also defeated the `power >= 1` test guard. Fail on it. - Only the (s=0, t=0) generator is seeded with a weight, so a module that is not cyclic on a degree-0 class left generators unweighted and panicked in the verify path far from the cause. Reject such modules up front. Seeding caller-supplied cell weights is left for the follow-up that needs them. The example now uses `trivial_module` and the `CTauResolution` alias instead of rebuilding both.

Opening the save directory is a recoverable I/O condition that `Resolution::new_with_save` already reports as a `Result`; turning it into a panic left callers of a public constructor no way to handle a bad or unwritable path. Propagate it instead. The examples that build resolutions live in the follow-up tranches, so they are updated when those rebase onto this.

Now that the constructors return `Result`, the cyclic-module restriction is reportable: `compute_weights` bails instead of asserting, and `with_module` propagates it. The `module_from_json` example (the Moore space) is cyclic on x_0 and so is supported; say what the restriction actually is rather than leaving a reader to find it by hitting it.

Second tranche of the motivic stack, after the algebra engine (#266, merged).
Blocked on #292 — nothing else.
What this is
The deformation approach to the C-motivic Adams E₂: resolve over the mod-τ algebra with the ordinary engine, then lift.
CTauAlgebra—Algebra. This is what the existing resolution engine resolves, unchanged, so the classical path stays bit-identical.MotivicResolution— resolve the trivial module overpersist— cache the resolution and the lift to disk.resolve_motivic_ctauexample.Why it needs #292
CTauAlgebratherefore multiplies throughmilnor_productfrom #292 rather than reimplementing the walk — one algorithm under test instead of two, which is the motivation #292 itself gives.A test cross-checks that against the engine's independent product (the Kong–Lin closed form from #266) over every pair up to total degree 5, and asserts some product genuinely drops a τ-divisible term.
milnor_producttakes its left factor first, while the engine'sproduct_indexedorders its arguments the other way. The two agree exactly under that transposition, but the failure mode is a well-formed wrong answer rather than an error.Deferred to the follow-ups
The Ext DGA, the deformation spectral sequence, products and Massey products (#289, #290). Their module declarations and the tests that assert on them land with those tranches — so
persist's round-trip test arrives with the cohomology tranche, since it asserts on τ-module torsion.Status
build/clippy(fullcargo hackfeature powerset) and nightlyfmt --allclean, 0 rustdoc warnings. 3 motivic tests inext(module descriptors, and the lift being a complex that reduces correctly mod τ) and 30 inalgebra, including the cross-checks against the classical Milnor algebra.Summary by CodeRabbit
