There was a problem hiding this comment.
When timing a restricted system, the lazy initializer calls load_coeffs(0), and load_coeffs translates that false value into the time_fit_inference_df_unrestricted.pkl path. Since the surrounding change explicitly disables UHF selection, every default singlet calculation now uses unrestricted coefficients instead of the restricted coefficients used previously, silently producing incorrect timing estimates.

Fixed in 6d5efec — and the root cause was one layer deeper than the call site.
Calling load_coeffs(True) would have raised KeyError: 'fit_label': the packaged time_fit_inference_df_restricted.pkl was the untouched pre-PR file (10 rows, no fit_label column), while the new basis-aware fit (13 rows, fit_label ∈ {Augmented, Non-augmented, All data}) that predict_timing actually needs had been written to the unrestricted filename.
That new file is a restricted refit, not UHF data:
wB97X-D,wB97X-V,FNO-CCSD,FNO-CCSD(T)coefficients are byte-identical to the old restricted fit.- It contains
FNO-CCSD(T), which the pre-PR code explicitly refused for an unrestricted reference. - Its sha256 does not match the pre-PR unrestricted pickle.
So the fix moves the basis-aware fit to time_fit_inference_df_restricted.pkl, deletes the stale/unused unrestricted file, and drops the restricted flag from load_coeffs() entirely since UHF is no longer supported. Runtime behavior is unchanged; the naming and the API now match reality.

| raise ValueError("input geometry must be a dimer") |
There was a problem hiding this comment.
If a directory contains a parseable molecule that is not a two-fragment dimer, this exception now escapes parse_geoms and aborts processing of every otherwise valid file in the directory. The removed per-file exception handler previously logged and skipped such entries, which is important for this folder-oriented API; the validation should remain inside per-file fault isolation.

Fixed in 6d5efec. Confirmed as a regression: the try/except wrapping each file was removed, so raise ValueError("input geometry must be a dimer") aborted the whole directory.
The check now logs and continues. Note there was a second latent bug in the same block: id.append(...) and n_atoms.append(...) ran before the fragment check, so simply swapping the raise for a continue would have desynchronized the output column lengths. The validation is now performed before those appends.

There was a problem hiding this comment.
When Psi4 cannot build a wavefunction/grid for one molecule-basis pair—for example because the requested basis is unavailable for an element—the exception now propagates through build_inference_table and terminates the entire multi-geometry, multi-basis run. This path previously returned a NaN timing-variable vector so the remaining requested calculations could still produce results; the auxiliary-basis build has the same regression.

Fixed in 6d5efec. Confirmed as a regression — both try/except blocks (wavefunction/grid build and the JKFIT auxiliary basis build) were removed in this PR and have been restored, each returning np.array([np.nan] * 4) so one bad molecule-basis pair no longer terminates a multi-geometry, multi-basis run.

During GPU training, evaluating a zero-dimensional CUDA tensor in this Python if forces a device-to-host synchronization on every SCF iteration, potentially adding 200 serial synchronization points per batch and creating a graph break for compiled execution. Keep the convergence check device-side or otherwise avoid a Python tensor predicate in the hot loop.

Not changing this one, deliberately.
The pattern if delta < convergence_threshold: break on a 0-dim tensor is the established SCF convergence idiom throughout this codebase — multipole.py:1215 and :1592, AtomModels/ap3_atom_model_frozen.py:598 and :956, and pre-existing mtp_mtp.py kernels at lines 2675, 2924, 3132, 3343, 3477. The new Rackers kernel follows it. Making this one call site device-side while leaving every sibling untouched would be inconsistent, and eliminating the Python predicate means giving up early exit (the loop would always run all 200 iterations), which is a worse trade for CPU training.
The related finding about geometric_mean_edge_values was actionable and is fixed in 6d5efec, because that helper runs six times on every forward pass rather than once per SCF iteration, and its check could be removed under tracing without changing semantics.

Offset per-dimer indices before constructing dimer_ind_full.
The proposed code concatenates raw per-item data.dimer_ind and data.dimer_ind_lr tensors. The fixture sets both tensors to zero for every item, but the test requires [0, 0, 1, 1, 0, 0, 1, 1]. Direct concatenation therefore produces eight zeros and assigns edges from different batch items to the same dimer.
Reuse the existing per-item offset lists used for the other index fields, then concatenate the short-range domain before the long-range domain.

Skipping — the implementation already does this; the finding is against the plan document snippet, not the shipped code.
All three collate functions overwrite the per-item index in place before concatenating, so the offsets are applied:
# src/apnet_pt/pt_datasets/ap2_fused_ds.py:277-281
data.dimer_ind = torch.ones(data.e_ABsr_source.size(0), dtype=...) * i
data.dimer_ind_lr = torch.ones(data.e_ABlr_source.size(0), dtype=...) * idimer_ind_full = torch.cat((dimer_ind_cat, dimer_ind_lr_cat)) then matches e_ABfull_* = torch.cat((sr, lr)) element for element, in the same short-range-then-long-range order. The Rackers models use ap2_fused_collate_update / ap2_fused_collate_update_no_target, both of which follow this ordering.
Separately worth flagging for a follow-up (pre-existing on main, untouched here): ap3_fused_collate_update builds e_ABfull_* as cat([all_sr, all_lr]) but dimer_ind_full as cat([per-item sr+lr]). Those two orderings disagree for batch size > 1. Nothing consumes dimer_ind_full on that path today, so it is latent, but it should be made consistent with the other two collates.

🌐 Web query:
PyTorch torch.compiler.is_compiling documentation returns True during torch.compile torch.export tracing runtime compiled graph
💡 Result:
The function torch.compiler.is_compiling is documented to indicate whether a graph is being executed or traced as part of torch.compile or torch.export [1][2]. In practice, the behavior of this flag has evolved to address limitations regarding when it returns True: 1. Relationship with torch.export: Historically, the underlying _is_compiling_flag was primarily set during the compilation process of torch.export [3][4]. 2. Relationship with torch.compile: While torch.compiler.is_compiling is intended to support both torch.compile and torch.export, users have reported instances where it returned False during torch.compile sessions [3]. Recent updates (e.g., in commit 80dd86c) have aimed to fix this by ensuring the _is_compiling_flag is set for the entire duration of a torch.compile session, allowing code executing within that session (such as custom backends or parts of AOTAutograd) to correctly observe the flag as True [5]. 3. Scope and Limitations: It is important to distinguish this from more specific flags: - torch.compiler.is_dynamo_compiling: Specifically indicates if the graph is being traced via TorchDynamo [6][7]. - torch.compiler.is_exporting: Specifically indicates if the graph is being traced via torch.export [6][4]. If you are experiencing unexpected results where the flag returns False during a session where you expect it to be True, verify your PyTorch version and ensure you are using a build that includes recent fixes for the session-wide scope of the flag [5].

During torch.compile tracing, torch.compiler.is_compiling() skips both checks. Later calls can pass selected NaN or Inf values to torch.sqrt and return non-finite energies. Add a compiler-compatible validation or validate inputs before every compiled call. Add compiled tests for non-finite source and target values.

Lines 431 to 432 in 6d5efec
Require a geometry path when invoking the script
Running this module directly now always calls main() without arguments, while the new main implementation immediately rejects a missing geom_path. Consequently python src/qcml_mcp/ie_time_esimator_script.py fails before doing any work, whereas the previous script entry point used its configured geometry directory; script mode should parse and pass a required path or retain a usable default.

Accessing qcml_mcp.server or executing from qcml_mcp import server now calls this hook, whose relative from . import server performs another attribute lookup on the package and re-enters the same hook until a RecursionError occurs. This prevents the package's primary server API from being accessed even when all optional MCP dependencies are installed; load the submodule through importlib.import_module() or otherwise bypass package attribute resolution.

When this executable is launched from outside the repository root—for example, bash /workspace/QCMLForge/run.sh from a scheduler's working directory—./train_models.py is resolved against the caller's current directory and Python exits with “can't open file” before either training starts. The new test invokes the script from a scratch directory but uses a recorder that never opens this argument, so it does not expose the failure; derive the repository directory from ${BASH_SOURCE[0]} and use it for the entry point (or change into it explicitly).

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Normalize whitespace before the help-text substring check.
argparse wraps help text to the terminal width reported by shutil.get_terminal_size(), which follows the COLUMNS environment variable. If the width is narrow, "exactly four" wraps across a newline and indentation, and the assertion at line 2891 fails even though the help text is correct. Collapse whitespace first so the check does not depend on the terminal width.

- help_output = capsys.readouterr().out

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Any import or execution of qcml_mcp.ie_time_esimator_script now fails before reaching the timing API: this except is indented outside the inner try while still inside the outer try, producing SyntaxError: expected 'except' or 'finally' block (confirmed with python -m py_compile). Re-indent the per-file parsing handler and its successful append block so the module can be imported.

When model_out already exists, or an explicit Rackers pre_trained_model_path is supplied, this branch still constructs AtomTypeParamModel and immediately loads am_model_path and atom_type_param_model_path. Resuming therefore fails if either original component checkpoint has been moved or deleted, even though the self-contained outer Rackers checkpoint reconstructs its nested atom hierarchy and ignores the newly constructed model; defer these component loads whenever pretrained_model is set.

The new CLI-test helper replaces production functions and global process state through monkeypatch, and the repository explicitly prohibits monkeypatch logic in tests. Use an injected callable/parser seam or execute the CLI against a recorder instead so these tests exercise behavior without runtime patching.

The added Rackers test suite repeatedly uses pytest's monkeypatch fixture to replace production functions and global process state, including the damping kernels here. This directly violates the repository's explicit prohibition on monkeypatch logic in tests; use injected callables, explicit fake objects, hooks, or subprocess-based CLI tests instead.

For every Rackers calculation, this call rebuilds _rackers_scf_plan, even though its inputs—polarizabilities, edge indices, and mutual interaction tensors—are invariant across the loop. On dense dimers that converge slowly, the default 200 iterations therefore repeat four large index_select/multiply operations and allocate four edge-by-3-by-3 tensors each time, significantly increasing training and inference cost. Build the plan once before the loop and invoke _rackers_scf_step with it on each iteration.

There was a problem hiding this comment.
When a batch mixes a monatomic monomer with a polyatomic monomer on the same side, this inherited forward path crashes: AtomTypeParamNN.forward removes the isolated atom from K_filtered, but computes each readout update for every atom and then adds tensors with different first dimensions. This affects both Rackers prediction with batch_size > 1 and training on mixed molecular/atomic dimers; the update should be masked consistently with keep_mask rather than relying on all atoms having intramolecular edges.

There was a problem hiding this comment.
When the unconstrained HFVR/valence-width submodel predicts a negative width for one endpoint and a positive width for the other, sigma_A * sigma_B is negative and this square root produces NaNs, causing the overlap model's predictions and training loss to become NaN. The Rackers parameters are explicitly constrained positive, but these widths are not; validate or positively transform them before evaluating the overlap correction.

fix: unblock CI collection and address review findings
CI failed with exit code 2 during collection: tests/test_select_LoT_skill_script.py
imported qcml_mcp, whose __init__ eagerly imported the MCP server (and thus the
optional `mcp` SDK), and the module also requires Psi4. Neither is available in
the CI environment.
CI unblock:
- Import qcml_mcp.server lazily via module __getattr__ so the timing estimator
and qcml_mcp.timings stay usable without the MCP server dependencies.
- Guard the timing-estimator integration module with pytest.importorskip("psi4").
- Register the `slow` marker.
- Ship qcml_mcp/data as a real package (setup.cfg package_data, MANIFEST.in) so
the packaged coefficients survive a non-editable install.
Timing estimator (codex P1/P2, CodeRabbit):
- load_coeffs(0) silently selected the unrestricted coefficient path. The new
basis-aware fit was stored under the unrestricted filename (it is a restricted
refit: four methods are byte-identical to the old restricted coefficients and
it includes FNO-CCSD(T), which was never fit for UHF). Move it to
time_fit_inference_df_restricted.pkl, drop the restricted/unrestricted flag,
and delete the unused file. Behavior is unchanged.
- Restore per-file fault isolation in parse_geoms so a non-dimer geometry no
longer aborts the whole directory, and validate fragments before appending to
id/n_atoms so the output columns stay the same length.
- Restore the NaN fallbacks around the Psi4 wavefunction/grid and auxiliary
basis builds so one bad molecule-basis pair no longer kills a whole run.
Rackers damping (CodeRabbit):
- geometric_mean_edge_values ran two Python tensor predicates six times per
forward pass, adding graph breaks and device syncs to the compiled training
path. Skip them while tracing via torch.compiler.is_compiling(), which folds
to a constant, and cover the compiled path with a fullgraph test.
Tests (CodeRabbit):
- Stack the controlled Rackers parameter sentinel along dim=1 so it matches the
[n_atoms, 4] head contract for any atom count instead of only four atoms.
- Assert the closed-form direct and mutual Thole damping values so a mutual
implementation reusing the direct formula cannot pass.
- Run run.sh from a scratch directory so the relative default MODEL_DIR is never
created inside the repository, and assert where it lands.
- Assert the timing estimator produces at least some finite predictions.
Other:
- Rename run.sh's OMP_NUM_THREADS override to TRAIN_OMP_NUM_THREADS; the
standard OpenMP variable is commonly exported by batch schedulers and would
silently replace the intended default.
- Drop the 7 MB training checkpoint models/ap3_saptpbe0/1/rackers_thole_1.pt
that was committed as a byproduct of launching a training run.

fix(dataset): align full AB edge lists with dimer_ind_full
`ap2_fused_ds.ap3_fused_collate_update` built `dimer_ind_full` per batch item
as [sr_i, lr_i] while building `e_ABfull_source/target` as
(all short-range, all long-range). The two layouts disagree for any batch
larger than one, so `scatter_sum_compile(E, batch.dimer_ind_full, ndimer)`
attributed pair energies to the wrong dimer. With three items of three
short-range and one long-range edge each, `dimer_ind_full` was
[0,0,0,0,1,1,1,1,2,2,2,2] where the true per-edge owners were
[0,0,0,1,1,1,2,2,2,0,1,2].
Accumulate the full edge lists per item so they match `dimer_ind_full`, which
also makes this function agree with the identically named canonical
`ap3_fused_ds.ap3_fused_collate_update` (whose grouped variant is commented out
in favor of the per-item layout). Nothing imports the ap2_fused_ds copy today —
all AP3 models take `ap3_fused_collate_update` from `ap3_fused_ds` — so this
was latent, but it would have corrupted any future consumer.
Audited every collate function emitting these fields. The six in
`ap3_fused_ds.py` and `ap3_fused_fsapt_ds.py` already accumulate
`local_e_ABfull_*` per item and are correct; the two `ap2_fused_*` functions use
the grouped layout consistently on both sides and are also correct.
Add `test_full_edge_dimer_index_aligns_with_full_edge_lists`, which checks the
layout-independent invariant `dimer_ind_full[k] == molecule_ind_A[e_ABfull_source[k]]
== molecule_ind_B[e_ABfull_target[k]]` across five collate functions, using
asymmetric monomer sizes and unequal short/long edge counts so a mis-grouped
index cannot coincidentally align. Verified the test fails on the pre-fix code.

refactor(dataset): drop dead ap2_fused_ds.ap3_fused_collate_update
This 175-line function was an unused duplicate of the canonical
`ap3_fused_ds.ap3_fused_collate_update`. Every consumer -- `apnet3_fused.py`,
`apnet3_d3_fused.py`, `apnet3_fused_variants.py`, and `test_freeze_unfreeze.py`
-- imports the name from `ap3_fused_ds`, never from `ap2_fused_ds`. Verified no
remaining references: no importers, no `__all__`, no star imports, no
`pt_datasets/__init__` re-export, and no string or `getattr` lookups.
The previous commit corrected this copy's full-edge ordering; deleting it
removes the divergence risk entirely rather than leaving two implementations of
the same name to drift apart again.
Repoint `test_full_edge_dimer_index_aligns_with_full_edge_lists` at the two
canonical `ap3_fused_ds` collates, so it now covers the four live functions that
emit `e_ABfull_*`/`dimer_ind_full`. Confirmed the test still guards real code by
mutating `ap3_fused_ds.ap3_fused_collate_update` to the grouped ordering and
watching it fail, then restoring.
Also document the element-wise alignment between `dimer_ind_full` and
`e_ABfull_source/target` in both surviving `ap2_fused_*` collate docstrings.

qcml_mcp.server imported FastMCP unconditionally, so the module could not be imported at all without the optional `mcp` extra, which CI does not install (`pip install -e . --no-deps`). Scope the FastMCP import behind a try/except and fall back to a small stand-in whose tool() returns the function unchanged, matching FastMCP's own behavior. The module-level `mcp` object is preserved so the FastMCP CLI convention still works, and any real server operation raises with install guidance instead of failing obscurely. Making the module importable exposed a second, previously masked problem: `from .timings import estimate_timings` fails when psi4 is absent, and the existing "run as a script" fallback then reported a misleading missing `timings` module. Separate the two imports so a missing psi4 leaves estimate_timings as None, and make the existing is_psi4_installed() guard raise instead of printing and falling through into a crash. Cover both paths in tests: the fallback is exercised in a subprocess that blocks `mcp` on sys.meta_path so it runs even where the extra is installed, and the real-FastMCP assertions are gated behind pytest.importorskip with the existing `mcp` marker.

There was a problem hiding this comment.
When the nested atom-type model predicts an HFVR of exactly zero, abs leaves it at zero, so the corresponding polarizability becomes zero. Both Thole kernels then divide by (alpha_i * alpha_j) ** (1/6); this produces an infinite damping argument and a NaN lambda_5 through the resulting inf * exp(-inf), causing the SCF calculation to exhaust its iterations and raise for that dimer. Clamp these ratios to a positive epsilon, as is already done for the valence widths.

PR #24 shipped three things alongside the Rackers implementation that the distillation did not pick up. All three apply to code this branch already has, so they come over here: - README: the optional-MCP install note, the Rackers CLI walkthrough, and two stale pointers -- `--train_ap2` was renamed `--train_apnet APNet2` and the experiment-tracking link pointed at a `docs/training-with-wandb.md` that does not exist, while `docs/wandb.md` does. Every flag and model name in the new text was checked against `train_models.py`. - `docs/specs/wandb-training.md` -> `docs/design/wandb-training.md`, with the model-inventory table row extended to name the two Rackers harnesses. - `.gitignore`: `*.pdf` and `docs/superpowers`. The five `docs/superpowers/` files are untracked as a consequence. They are superpowers-workflow plans and design specs -- two are agent task lists with `REQUIRED SUB-SKILL:` headers -- and #24 had already decided that directory is not a package deliverable. They remain in this branch's history. The CLIFF-2 paragraph is not from #24. It is here because the routes this PR exists to add had no README mention at all.

Intent
Primary goal: add two trainable Rackers-style Thole damping models for SAPT electrostatics and induction: RackersTholeDampingModel for pure induced-point-dipole induction, and RackersTholeDampingOverlapModel which adds the existing overlap correction. This includes the physics kernels, a fixed four-head atom-type model predicting positive electrostatic damping, direct Thole damping, mutual Thole damping, and induction-overlap damping; shared high-level training and prediction harnesses; strict standalone v2 checkpoint metadata covering model type, parameter ordering, dimer mode, and nested model configuration, with support for nested frozen AtomTypeParamNN models and explicit unfreezing; and exact train_models.py CLI routes for both Rackers model identifiers.
Deliberate design decisions: direct damping is routed through the permanent fields and the final induction energy while mutual damping is routed through the SCF update; atom-wise direct and mutual Thole values are combined independently using geometric means on AB, AA, and BB edges; the overlap output is preserved in both variants but only consumed by the overlap-enabled model; full dimer edge indices are used for Rackers target aggregation without changing legacy model aggregation. The branch also carries timing-estimator and level-of-theory-selection updates from its ancestry.
Most recent request, implemented in commit 43df941d: the user asked to "make fastmcp imports scoped to make optional and skipped in pytest if not importable". src/qcml_mcp/server.py previously did an unconditional
from mcp.server.fastmcp import FastMCP, so the module could not be imported at all without the optionalmcpextra, which CI never installs (it runspip install -e . --no-deps). The FastMCP import is now scoped behind try/except with a small _MissingFastMCP stand-in whose tool() returns the function unchanged, matching real FastMCP behavior. Keeping a module-levelmcpobject is deliberate: the FastMCP CLI convention resolves that global, so it must not be moved into a factory function. Any real server operation on the stand-in raises ImportError with install guidance.Making the module importable exposed a second, previously masked defect that was also fixed in the same commit:
from .timings import estimate_timingsraises ImportError when psi4 is absent (estimate_timings.py doesimport psi4at line 1), and the pre-existing "fall back to absolute imports when run as a script" except branch then reported a misleading "No module named 'timings'". The two imports are now separated so a missing psi4 leaves estimate_timings as None. Relatedly, the existingif is_psi4_installed() is False:guard only printed and then fell through intoestimate_timings.compute_psi4_time_estimation_variables(...), which crashed; since the module is now importable without psi4 that path became reachable, so the guard was changed to raise RuntimeError with the same message. Changing that print to a raise is intentional, not an oversight.Test approach for the new work is deliberate: the fallback is exercised in a subprocess that blocks
mcpvia a sys.meta_path finder, so it genuinely runs the fallback even in environments where the extra IS installed rather than silently passing; the real-FastMCP assertions are gated behind pytest.importorskip using the existingmcppytest marker declared in pyproject.toml. Verified locally: without mcp, 2 pass and 1 skips; with a working mcp install, all 3 pass; full-suite collection goes from 389 to 391 tests with zero collection errors.The following are DELIBERATE user decisions and must NOT be flagged as mistakes or regressions:

Risk Assessment
Testing
After unavailable bare-Python probes and a CUDA-driver-sensitive RNG failure, I constrained the test RNG to CPU and the focused Rackers, model-I/O, polarization, and optional-MCP tests passed; the LoT suite correctly skipped without its optional dependency, while API checkpoint/prediction, CLI-help, and fallback-import artifacts demonstrated end-user behavior.
