lcy-seso c2e01ac8d4 [Fix][Manifest] adopt documented shape/workload format in new elementwise families
- Convert signature shape values from YAML lists to string form ("[M, N]")
  in elementwise_generative.yaml and elementwise_fused_gated.yaml to match
  docs/design/manifest.md R8 + the convolution.yaml precedent so the
  validator can bind shape symbols.
- Add per-input workload shape keys (device_carrier_shape, x_shape) to
  every workload row to satisfy the workload schema documented in
  docs/design/manifest.md and used across normalization.yaml etc.
- Restore exception class/message in check_c4_forward_signature_parity's
  warning when inspect.signature(forward) raises.

lcy-seso 855adcf333 [Maintain][Manifest] align L1 generative detection with C4 positional filter
The L1 carve-out at check_l1_pyfile_signature used _get_forward_params,
which counts KEYWORD_ONLY params. check_c4_forward_signature_parity
filters to POSITIONAL_ONLY / POSITIONAL_OR_KEYWORD before applying its
ref_api == none + zero-positional-args carve-out. A forward(self, *,
dtype=None) class therefore diverged: L1 emitted a [signature] error
while C4 returned []. Extract _forward_positional_params and use it from
both sites so the two carve-outs stay in lockstep.

lcy-seso ff32723d16 [Maintain][Manifest] add generative-op carve-out + restore alibi/sinusoidal
L1 and C4 forward()-arity checks now skip when ``ref_api: "none"`` and
``forward()`` takes zero positional args. The five elementwise ops
without manifest entries -- AlibiFwdOp, SinusoidalFwdOp, plus the three
fused-gated entries already present -- are all covered by the manifest;
the two generative ops carry a single ``device_carrier`` scalar input to
satisfy ``test_every_signature_has_inputs_and_outputs`` while the new
carve-out unblocks the forward()-order check.

[Chore][Release] merge testbed into main: op-family alignment + new ops (#1380)
## Summary
Merge 27 commits accumulated on `testbed` into `main`. Covers
manifest-spec alignment for the elementwise (unary/binary/multi-input),
reduction, and normalization families; new ops (LerpTensorFwd,
Reciprocal, fused tanh-GELU, InstanceNormFwdOpNoAffine,
GroupNorm/InstanceNorm no-affine variants); shared dispatch/refactor
cleanup; and supporting manifest DSL (`promote_int_to_float`), tests,
and process docs.

## Highlights
- **Family alignment to manifest spec**: elementwise_unary_activation
(#1211), elementwise_binary (#1222), elementwise_multi_input (#1229),
reduction (#1235), normalization (#1240).
- **New ops / variants**: LerpTensorFwd (#1264), Reciprocal +
`promote_int_to_float` DSL (#1252), fused tanh-GELU (#1262),
GroupNorm/InstanceNorm no-affine (#1274, #1284),
InstanceNormFwdOpNoAffine running-stats (#1375).
- **Refactors**: activation shared bases (#1230), dispatch_kernel
routing (#1260, #1368), normalization hotfix cleanup (#1256),
elementwise_binary torch-fallback removal (#1248).
- **Tests / docs**: manifest-driven L1 parity for elementwise_binary
(#1370), drop manifest-mirror tests (#1374), FLIP_STATUS carve-out
(#1258), spec-only -> implemented promotion rule (#1271).

## Test plan
- [ ] CI green on the PR branch
- [ ] \`make test\` passes locally
- [ ] Manifest validator and strict-parity gates pass

[Feat][Manifest] strict parity CI for status: implemented ops (#1292)
Refs #1291 · backlog + flip-to-blocking in #1372

Adds C1–C7 strict parity gates to `scripts/validate_manifest.py` for
`status: implemented` ops; `spec-only` skip. Removes the
`parity_opt_out` escape hatch.

| Check | Catches |
| --- | --- |
| C1 / C2 | `_infer_output_shapes` / `_validate_dtypes` disagrees with
manifest |
| C3 | ctor param defaults + kw-only flag mismatch |
| C4 | forward positional names mismatch |
| C5 | Slot S12+S13: `__init__` lacks `kernel_map` kwarg, or body never
calls `self.dispatch_kernel(...)` / `super().__init__(...)` (static
inspect + AST; no construction) |
| C6 / C7 | `_validate_dtypes` / `eval_roofline` is the base stub |

Default **advisory** — failures → warnings, exit 0. `--strict` /
`MANIFEST_STRICT_BLOCKING=1` flips to blocking. `--levels` gates:
C3/C4/C5 ↦ `signature`, C6 ↦ `dtype`, C7 ↦ `bench`.

## Test plan

- [x] pre-commit
- [x] `pytest tests/test_validate_manifest.py -q` — 205 passed (+19
nodes)
- [x] `python scripts/validate_manifest.py` — exit 0 (advisory)
- [x] `python scripts/validate_manifest.py --strict` — exit 1 (83
errors: 22 ctor + 46 + 15 stub; tracked in #1372)

[Refactor][Hygiene] strip development-process metadata from shipped source (#1290)
## Summary

Apply `.claude/rules/code-style.md` "no development-process metadata in
shipped source" across `tileops/` `tests/` `benchmarks/` `scripts/`.
Rewrite `pytest.skip`/`xfail` reasons, docstrings, comments to describe
invariants instead of referencing issue/PR numbers and AC labels.
Prose-only — no behavior change.

## Scope (24 files)

- 16 `pytest.skip`/`xfail` reason rewrites (tilelang 0.1.9 batch, rope,
attention, recurrent linear-attention) + shared
`TILELANG_019_SKIP_REASON` in two conftests
- AC-label strips in 9 test files / 1 bench /
`scripts/validate_manifest.py`
- `TODO(#NNNN)` strips in `tileops/kernels/convolution.py` (×2),
`reduction/logsumexp.py`, `reduction/softmax.py`
- Historical PR refs in `tests/test_validate_manifest.py` rewritten to
describe the contract

Excluded: `tileops/manifest/`, `docs/`, `.claude/` (out of rule scope).
`FIXME(staged-rollout)` blocks already compliant. Single-digit "Finding
#N" labels not matched by the rule's `#[0-9]{3,}` regex.

## Test plan

- [x] discovery scan returns 0 matches
- [x] `pytest tests/ --co -q` — 2752 collected
- [x] touched test files: 186 + 53 passed
- [x] pre-commit clean

[Refactor][Manifest] drop eager ops import from tileops package (#1219)
Closes #1216

## Summary

- Drop `from . import ops` (and the matching `__all__` entry) from
`tileops/__init__.py`. Importing `tileops` no longer pulls in
`tileops.ops` or any `tilelang.*` module as a side effect.
- Replace the `importlib.spec_from_file_location` workaround in
`scripts/validate_manifest.py` with a direct `from
tileops.manifest.shape_rules import dim_range_validity, dim_uniqueness,
reduced_axes`. Drop the `_SHAPE_RULES_PATH` / `_shape_rules_spec` /
`_shape_rules_module` plumbing and the underscore-prefixed rebindings.

## Test plan

- [x] AC-1: Modified files pass existing tests.
- [x] AC-2: `import tileops` does not load `tileops.ops` (verified via
`sys.modules` snapshot).
- [x] AC-3: `from tileops.manifest import shape_rules` does not load
`tileops.ops` or any `tilelang.*` module (verified via `sys.modules`
snapshot).
- [x] AC-4: `scripts/validate_manifest.py` uses standard `from
tileops.manifest.shape_rules import ...` instead of
`importlib.spec_from_file_location`; the `_SHAPE_RULES_PATH` literal is
removed.
- [x] AC-5: `python scripts/validate_manifest.py` exit 0 on the
checked-in manifest, output bit-identical to pre-change baseline.

[Feat][Manifest] AST-walk L0 typo defense for shape_rule callables (#1217) (#1218)
Closes #1217

## Summary

- Add `_check_shape_rule_callables` helper in
`scripts/validate_manifest.py` that AST-walks each `shape_rules` entry
at L0 and rejects any direct `Name(...)` call whose name is not in
`_SHAPE_RULE_BUILTINS`.
- SyntaxError in a shape_rule now surfaces as a single `[schema]` error
at L0 instead of an L2 eval-time warning, so typos are caught without L2
mock-input setup.
- Add four `TestSchema` cases covering unknown callable rejection,
known-callable acceptance, attribute-call passthrough, and SyntaxError
rejection.

## Test plan

- [x] AC-1 — Modified files pass existing tests. (`python -m pytest -q
tests/test_validate_manifest.py` → 185 passed)
- [x] AC-2 — Typoed shape_rule callable names surface as `[schema]`
errors at L0, not L2 NameError warnings.
- [x] AC-3 — Existing `tileops/manifest/*.yaml` shape_rules pass the new
L0 check with no false positives. (`python scripts/validate_manifest.py`
→ exit 0)
- [x] AC-4 — Test coverage for unknown callable, known callables,
attribute call, and syntax error cases.
- [x] AC-5 — SyntaxError in a shape_rule moves from L2 eval warning to
L0 schema-level rejection without L2 mock input setup.

Growth: +2.2%
```

**Justification:** Four new tests are required by AC-4, one per
shape_rule callable case (unknown name → reject, known names → pass,
attribute call → pass, SyntaxError → reject). Each case exercises a
distinct branch of the new AST walk in `_check_shape_rule_callables`;
collapsing them would lose coverage of the L0/L2 boundary that this PR
establishes.

[Refactor][Manifest] introduce shape_rules helpers as flat shape_rule builtins (#1210)
Closes #1209. Follow-up #1212 migrates `tileops/manifest/reduction.yaml`
to reference these helpers.

## Summary

Tooling-only PR — no `tileops/manifest/*.yaml` data is modified.

- `tileops/manifest/shape_rules.py`: three pure-Python helpers —
`dim_range_validity(x, dim) -> bool`, `dim_uniqueness(x, dim) -> bool`,
`reduced_axes(x, dim) -> frozenset` — preserving the inline-form
malformed-dim semantics verbatim (TypeError on malformed input is
classified by the validator as an eval-error warning, bit-identical
pre/post).
- `scripts/validate_manifest.py`: helpers wired into
`_SHAPE_RULE_BUILTINS` alongside `len`, `range`, `broadcast_shapes`,
etc. Callable by bare name from any shape_rule body. The dict is built
from an explicit `(name, callable)` list so a duplicate-name
registration fails the validator at import time instead of silently
shadowing.
- `.claude/domain-rules/`: drift-surface cleanup — trim reduction-dim
rule, dedupe Op-naming rule across three files, strip restatements that
the validator/type-system already enforces.
- `tests/test_validate_manifest.py`: drop per-case scaffolding tests;
fold pre-existing `TestShapeRuleBroadcastBuiltins` per-case property
tests into matrix tests.

## Test plan

- [x] `pytest tests/test_validate_manifest.py -q` → 181 passed
- [x] `python scripts/validate_manifest.py` → exit 0; pre/post diff
empty (pinned by `test_sum_rules_helper_inline_classification_parity`)
- [x] `tileops.manifest.shape_rules` exposes the three helpers via
`__all__` with docstrings
- [x] Helpers callable by bare name from shape_rules eval scope (pinned
by `test_shape_rules_helpers_callable_by_bare_name`, driven by
`__all__`)
- [x] `_SHAPE_RULE_BUILTIN_PAIRS` raises on duplicate names (pinned by
`test_shape_rule_builtin_pairs_have_unique_names`)
- [x] `.claude/domain-rules/manifest-spec.md` reduction-dim rule points
at `tileops.manifest.shape_rules`

## Test node delta

`tests/test_validate_manifest.py`: 190 → 181 (−9). +6 contract-level
tests for the new helper layer; −15 from folding
`TestShapeRuleBroadcastBuiltins` per-case tests into matrix tests with
no contract loss.

[Feat][Manifest] align where/clamp/masked_fill multi-input ops to pytorch api (#1109)
Closes #1088

## Summary

- Align the three multi-input elementwise op manifest entries (`where`,
`clamp`, `masked_fill`) to PyTorch's public API, per the manifest trust
model.
- Split families per the "No `Optional[Tensor]`" rule: `Clamp` family
becomes 4 entries (`ClampFwdOp` primary + `ClampScalarFwdOp` /
`ClampMinFwdOp` / `ClampMaxFwdOp` variants); `MaskedFill` family becomes
2 entries (`MaskedFillFwdOp` primary + `MaskedFillScalarFwdOp` variant).
- Update `WhereFwdOp.shape_rules` to use
`broadcast_shapes(condition.shape, input.shape, other.shape)` matching
`torch.where` broadcasting; remove inline BLOCKED notes from all three
families.
- Add `broadcast_shapes` and `is_broadcastable_to` to
`_SHAPE_RULE_BUILTINS` in `scripts/validate_manifest.py` (pure-Python,
no torch dependency) so manifest `shape_rules` can express NumPy/PyTorch
broadcast semantics.
- Add roofline blocks for the new `Clamp` and `MaskedFill` variants,
with `vars.N_total = product(broadcast_shapes(...))` for broadcasting
variants and `product(input.shape)` for the scalar-bound
`ClampScalarFwdOp`.
- All new / restructured entries land as `status: spec-only`; kernel and
op-class conformance is tracked in follow-up #1107.

## Test plan

- [x] AC-1: `WhereFwdOp.shape_rules` uses `broadcast_shapes(...)` and
matches `torch.where` broadcasting semantics; inline BLOCKED note
removed.
- [x] AC-2: Clamp family expressed as 4 entries (`ClampFwdOp` primary +
`ClampScalarFwdOp` / `ClampMinFwdOp` / `ClampMaxFwdOp` variants) with
`Number | None` for scalar params; inline BLOCKED note removed.
- [x] AC-3: MaskedFill family expressed as 2 entries (`MaskedFillFwdOp`
primary + `MaskedFillScalarFwdOp` variant) with bidirectional input/mask
broadcasting (out-of-place `Tensor.masked_fill` semantics) and `Number`
value type; inline BLOCKED note removed.
- [x] AC-4: `_SHAPE_RULE_BUILTINS` includes `broadcast_shapes` and
`is_broadcastable_to`, with unit tests in
`tests/test_validate_manifest.py`.
- [x] AC-5: `scripts/validate_manifest.py --levels schema` passes for
all affected entries.
- [x] AC-6: `where_fwd_roofline` and new variant roofline blocks are
consistent with the post-broadcast `N_total` convention.
- [x] AC-7: Follow-up issue filed (#1107) tracking kernel + op-class
conformance to all new / restructured entries.

Verification commands (all green locally):

- `pre-commit run --all-files` → all hooks pass
- `python scripts/validate_manifest.py --levels schema` → all manifest
checks passed
- `pytest tests/test_validate_manifest.py` → 190 passed, 3 warnings

Growth: +11.1%
```

**Justification:** The +19 nodes cover the new `_SHAPE_RULE_BUILTINS`
helpers (`broadcast_shapes`, `is_broadcastable_to`): direct unit
coverage of helper behavior (broadcasting equivalence, broadcast
failures, scalar/empty-shape edge cases, unidirectional
broadcastability) plus end-to-end coverage via `_eval_shape_rule` to
confirm the helpers are actually reachable from manifest `shape_rules`
strings. These helpers gate the new PyTorch-aligned `shape_rules` for
`where`, `clamp`, and `masked_fill`; without this coverage, the
broadcasting semantics of those entries are validator-untested.

[Refactor][Manifest] split elementwise.yaml into per-sub-family shards (#1095)
Closes #1093

## Summary

- Split `tileops/manifest/elementwise.yaml` (62 ops, ~2050 lines) into 4
sub-family shards by signature shape:
- `elementwise_unary_math.yaml` — 24 ops (~746 lines): unary math
(single-input single-output, math kernels)
- `elementwise_unary_activation.yaml` — 13 ops (~485 lines): unary
activations (single-input single-output, NN activations)
- `elementwise_binary.yaml` — 23 ops (~739 lines): binary (two-input
single-output)
- `elementwise_multi_input.yaml` — 2 ops (~84 lines): 3+ input or
multi-output
- Removed the monolithic `tileops/manifest/elementwise.yaml`; entries
moved verbatim via `ruamel.yaml` round-trip, preserving `family:
elementwise` on every entry.
- Updated `tileops/manifest/__init__.py` module docstring and
`docs/manifest.md` / `CLAUDE.md` to describe the sharded layout.

No op-code or kernel-code changes — pure manifest file partitioning.
Total op count stays at 114; `load_manifest()` / `load_workloads()`
behavior is dict-equal to upstream/main.

## Test plan

- [x] AC-1: `tileops/manifest/elementwise.yaml` removed; ops live in 4
sub-files, every shard < 1000 lines and ≤ 30 ops (largest: 746 lines /
24 ops).
- [x] AC-2: `load_manifest()` returns the same 114 op names with
dict-level content equal to upstream/main (verified via Python
comparison: `name_sets_equal=True`, `content_equal=True`).
- [x] AC-3: `python scripts/validate_manifest.py` exits 0 — "All
manifest checks passed" (58 warnings, unchanged from baseline).
- [x] AC-4: `pytest tests/test_ops_manifest.py
tests/test_validate_manifest.py tests/test_workloads_to_params.py` → 198
passed, matching upstream/main baseline (198 passed) at branch point.
- [x] pre-commit passed on all changed files.

## Additional context

Follows the same trust-model rules as PR #1092 (which sharded the
manifest into one-file-per-family): manifest-only PR, no op or kernel
changes bundled. The elementwise family was the only family still over
the ~1000-line / ~30-op soft cap after #1092 — this PR completes the
per-sub-family layout.

[Refactor][Manifest] flatten yaml top-level ops key (#1094)
## Summary

- Each family yaml previously wrapped its entries under a top-level
`ops:` key, costing one indent level on every entry without serving any
purpose — family scope is already conveyed by the filename, and the
loader just unwrapped the key.
- Flatten the format: each family file is now a direct mapping of op
name → entry. Updated 8 yaml files (4546 lines), the `tileops.manifest`
loader, the `--manifest-path` branch in `scripts/validate_manifest.py`,
the `tests/test_validate_manifest.py` fixtures, and the example in
`docs/manifest.md`.
- Pre-release project, so no compat shim — the old format is no longer
accepted.

## Test plan

- [x] pre-commit passed (full hook suite on all changed files)
- [x] `python scripts/validate_manifest.py` → `All manifest checks
passed.`
- [x] `pytest tests/test_validate_manifest.py
tests/test_gpu_smoke_policy.py` → 176 passed
- [x] `from tileops.manifest import load_manifest` smoke check → 114 ops
loaded

## Regression

- Loader migration is mechanical (`data.get("ops") or {}` →
`yaml.safe_load(...) or {}`). All 114 ops load identically; downstream
consumers (`load_workloads`, `validate_manifest`) untouched.
- `_load_manifest` private alias removed (no remaining callers in repo).

## Additional context

There is no near-term plan for family-level metadata. If that need
arises later, a wrapper can be reintroduced — YAGNI for now.

[Refactor][Manifest] split monolithic yaml into per-family package (#1092)
## Summary

- Split `tileops/ops_manifest.yaml` (monolithic, 4564 lines) into one
YAML file per op family under `tileops/manifest/` — `elementwise.yaml`
(62), `reduction.yaml` (19), `attention.yaml` (12), `normalization.yaml`
(10), `moe.yaml` (7), `scan.yaml` (2), `convolution.yaml` (2).
- Convert `tileops/manifest.py` into the `tileops/manifest/` package;
`__init__.py` scans the directory, merges all `ops` dicts, errors on
duplicate keys, caches with `lru_cache(1)`. Public API
(`load_workloads`) is unchanged; new helpers `load_manifest()` and
`manifest_files()` exposed.
- Update direct consumers: `scripts/validate_manifest.py` (default load
via package; `manifest_path=` kept for synthetic fixtures),
`tests/test_ops_manifest.py` (fixtures via `load_manifest()`),
`pyproject.toml` package-data, `.github/workflows/preflight.yml` path
globs.
- Synchronize all documentation: 22 `.md` files (CLAUDE.md, docs/,
.claude/skills/, .claude/domain-rules/, .claude/rules/) plus docstrings
in 5 benchmark files and `tileops/perf/formulas.py`. CLAUDE.md "Reading
the ops manifest" section and docs/manifest.md "Layout" section
rewritten for the new structure. `add-manifest` / `fix-manifest` skills
note family-file routing.

## Test plan

- [x] `python scripts/validate_manifest.py` passes
- [x] `pytest tests/test_ops_manifest.py tests/test_validate_manifest.py
tests/test_workloads_to_params.py` — 197 passed
- [x] pre-commit passed
- [x] `python3 -c "from tileops.manifest import load_manifest; assert
len(load_manifest()) == 114"` — round-trip preserves all 114 ops, no
duplicates

## Additional context

The split keeps the conceptual "single source of truth" (the merged
`ops` dict) while addressing the practical pain of one 4500+ line file.
Largest family file is `elementwise.yaml` at 2030 lines (62 ops); a
follow-up PR can sub-split elementwise into unary/binary/multi-input if
desired. No op or kernel code is touched, so this PR does not conflict
with the trust-model rule prohibiting joint op+manifest changes.

## Structural Readiness

All checks passed.

## Follow-up

Issues:
- #1093 — sub-split elementwise.yaml (2030 lines / 62 ops) into
unary/binary/multi-input sub-files.

[Feat][TOOLING] validator parity for _infer_output_shapes and _validate_dtypes (#1005)
## Summary

Add validator checks that ensure a concrete op's `_infer_output_shapes`
and `_validate_dtypes` agree with its manifest declaration. Introduces
L2 infer-shape parity and L3 dtype parity checks in
`scripts/validate_manifest.py`, plus documents the two new rows in the
Consistency Enforcement table and the `parity_opt_out` entry field.

Closes #994

## What this PR does

- **L2 infer-shape parity**: for each `status: implemented` op, invokes
`_infer_output_shapes` with concrete mock inputs and checks the returned
shapes against `signature.outputs[*].shape` declarations,
`signature.static_dims`, param defaults, and `shape_rules` (incl. R11a
comprehensions). Symbolic dims (`B`, `S`, `H`, `D`, …) are bound from
input shapes and also rebound from inferred outputs so output-only
symbols like conv `L_out` can be checked against rule-derived values.
- **L3 dtype parity**: validates `_validate_dtypes` behaviour against
`dtype_combos` (when present, exhaustive) or declared `dtype` unions
(full Cartesian product), plus out-of-union negative probes and
`same_as(ref)` identity probes on both branches.
- **Manifest-data validation (runs unconditionally in `check_l3`)**:
combo completeness (every combo row must cover every declared input),
invalid dtype tokens, unresolved / cyclic `same_as(ref)`, and union
values in combo entries are hard L3 errors regardless of whether the
class overrides `_validate_dtypes`.
- **`parity_opt_out`**: optional manifest entry field (`true` or subset
of `[shape_parity, dtype_parity]`) to suppress parity checks for ops
whose method genuinely needs GPU execution. Documented in
`docs/manifest.md` (Entry Structure) and `docs/ops-design-reference.md`
(Consistency Enforcement).
- **Security / bounds**: `eval()` for shape rules is restricted to a
builtins allowlist, AST-filtered for dunder attrs, and protected from
`ctx` overwriting `__builtins__`. Cartesian product iteration is bounded
by `_MAX_DTYPE_COMBOS = 4096` with deterministic skip + warning on
over-bound ops.
- **Policy (tightened over review rounds)**: unexpected body exceptions
from `_infer_output_shapes` / `_validate_dtypes` are **hard parity
errors by default**; reserve the soft-warning path for entries that
explicitly opt out. Signature-bind failures (via
`inspect.signature().bind`) remain a separate category.

## Test plan

- [x] **AC-1**: Modified files pass unit tests.
- Evidence: `python -m pytest tests/test_validate_manifest.py -q` → 170
passed.
- [x] **AC-2**: Validator L2 reports error when `_infer_output_shapes`
disagrees with `shape_rules` / declared shapes.
- Evidence: `TestInferShapeParity` covers incorrect infer, symbolic dim
mismatch, R11/R11a helper rules, input-only precondition separation,
conv-like output-only symbols, declared-output-shape exact match,
`self.attr` / `self.static_dim` mock populations,
body-exception-as-hard-error (+ opt-out downgrade).
- [x] **AC-3**: Validator L3 reports error when `_validate_dtypes`
accepts non-listed or rejects declared combos.
- Evidence: `TestValidateDtypesParity` covers union accept/reject,
`dtype_combos` accept/reject listed, first-rejected-later-accepted
enumeration, out-of-union probes (both branches), `same_as` identity
probes, signature-mismatch vs body-exception separation (body errors are
hard unless opted out), Cartesian bound skip with warning,
exhausts-the-union warning.
- [x] **AC-4**: Consistency Enforcement table adds two new rows.
- Evidence: `docs/ops-design-reference.md` adds rows for
`_infer_output_shapes` vs `shape_rules` (L2) and `_validate_dtypes` vs
`dtype_combos` / unions (L3), plus a "Parity check coverage" paragraph
documenting missing-override warning + `parity_opt_out`.
`docs/manifest.md` Entry Structure documents the `parity_opt_out` field.

## Integration check

```
python scripts/validate_manifest.py → exit 0, 0 ERROR lines, 48 WARNING lines
  (expected: missing-override warnings for implemented ops awaiting codegen
   migration + pre-existing bench warnings). "All manifest checks passed."
```

No existing Op required `parity_opt_out` under the tightened
body-exception policy.

## Test node-delta (testing-budget rule)

```
tests/test_validate_manifest.py     101     170      +69   (+68.3%)
```

Justification: the delta covers AC-1..AC-4 parity behaviour plus
regression coverage from seven review rounds:

- signature-bind vs body-exception separation (body errors are hard
L2/L3 by default, opted out via `parity_opt_out`)
- `same_as` fixpoint resolution (order-independent); pure-cycle and
dangling-ref diagnosis produce hard L3 errors with all cycle
participants named
- out-of-union negative probes on both branches (`dtype_combos` and
Cartesian), sourced from `_TORCH_DTYPES − declared` so sentinel
engulfment can't create a vacuous pass; full-coverage case emits a named
warning
- `same_as(ref)` identity probes on both branches
- mock `self` via `cls.__new__(cls)` with `signature.params` defaults,
`static_dims` resolved values, and primary `dtype` axis populated
- symbolic dim binding from `signature.*.shape`; output-only symbol
rebinding from inferred outputs (conv-like `L_out` scenarios)
- `static_dims` and scalar-int param defaults both pin
declared-output-shape positions to exact values (not just
rank/consistency)
- combo completeness (every row covers every declared input), invalid
dtype value rejection, union-in-combo-value rejection as hard L3
manifest errors — run unconditionally in `check_l3`, independent of
`_validate_dtypes` override status
- Cartesian product bounded by `_MAX_DTYPE_COMBOS = 4096` with
deterministic skip + warning
- `eval()` sandbox: restricted `__builtins__`, AST dunder-attr filter,
`ctx` cannot overwrite `__builtins__`

Tests are validator regressions, not broad combinatorics.

[Refactor][Roofline] remove manifest-level roofline evaluator (#1024)
## Summary

This PR now targets the design direction that target design should not
have a manifest-level evaluator. Instead of keeping a legacy evaluator
boundary, it removes the legacy evaluator surface and migrates current
callers.

- Delete `tileops/manifest_legacy_roofline.py`.
- Remove manifest exports for `_safe_eval`, `eval_roofline`,
`resolve_roofline_vars`, and `has_roofline_vars`.
- Move benchmark roofline consumption to op-local `eval_roofline()` and
`ManifestBenchmark(op_name, op, workload)`.
- Add local `eval_roofline()` implementations for the currently migrated
norm, MoE, reduction, and softmax-family benchmark surfaces.
- Update validator, tests, and roofline docs for the op-local evaluator
contract.

## Test Plan

- `ruff check` on changed Python files
- `python -m compileall tileops benchmarks scripts tests`
- `pytest tests/test_ops_manifest.py tests/test_workloads_to_params.py
tests/test_validate_manifest.py
benchmarks/tests/test_roofline_workload_protocol.py`
- `python scripts/validate_manifest.py`

Note: `validate_manifest.py` passes and still reports the existing
attention benchmark L4 warnings; those are pre-existing warnings outside
this cleanup scope.

## Follow-up

No follow-up issues or suggestions.

[CI] Run nightly inside containerized runner (#1017)
Closes #1016

## Summary

- Move nightly workflow execution to assume it already runs inside the
containerized self-hosted runner.
- Remove workflow-level Docker startup, workspace ownership fixes, and
the local tileops-runner:latest wrapper.
- Add a nightly runner verification script for cache env vars, cache
writability, and GPU visibility.

## Test plan

- [x] pre-commit passed during git commit
- [x] bash -n scripts/ci/verify_nightly_runner.sh
- [x] python -c "import yaml;
yaml.safe_load(open('.github/workflows/nightly.yml')); print('yaml ok')"
- [x] git diff --check -- .github/workflows/nightly.yml
scripts/ci/verify_nightly_runner.sh
- [x] rg -n "docker run|tileops-runner:latest|Fix workspace
ownership|/data/ci-cache" .github/workflows/nightly.yml returns no
matches
- [ ] actionlint .github/workflows/nightly.yml (not run locally;
actionlint is not installed)

## Additional context

This PR intentionally keeps the existing runner labels unchanged and
does not modify runner-maintenance.yml. Cache cleanup policy is left for
a separate follow-up, as scoped in #1016.

[Fix][CI] widen fork-PR gpu-smoke cache hits without widening write surface (#1009)
## Summary

Maximize cache hit rate for fork-PR `gpu-smoke` runs without widening
the write-path attack surface.

Three narrowly-scoped fixes:

1. **Narrow venv HASH** (`scripts/ci_venv_hash.py`): parse
`pyproject.toml` with `tomllib` and hash only `[project]` +
`[build-system]` + `[project.optional-dependencies]`. Edits to
`[tool.pytest]` / `[tool.ruff]` no longer bust the venv cache. Falls
back to full-file hash on parse failure, preserving the 16-char hex
format.
2. **Member-fork → trusted runtime path**
(`.github/workflows/gpu-smoke.yml` policy): when head repo differs from
base but `author_association ∈ {OWNER, MEMBER, COLLABORATOR}`, set
`is_fork=false` so the PR traverses the trusted runtime path
(`RUNTIME_ROOT=/home/ci-runner`). External contributors still go the
isolated path.
3. **Skip in-line atomic age-trim**
(`.github/actions/reclaim-runner-disk/action.yml`): add
`skip-atomic-age-trim` input (default `false`); `gpu-smoke.yml` passes
`true` so the destructive autotuner age-trim only runs via
`runner-maintenance.yml` (daily). Sentinel-repair remains always on.

Closes #1007

## Test plan

- **AC-1**: Changing `[tool.pytest]` / `[tool.ruff]` sections of
`pyproject.toml` does NOT change the computed venv HASH — pass. `python
-m pytest -q tests/test_ci_venv_hash.py tests/test_gpu_smoke_policy.py
tests/test_reclaim_action.py`: 26 passed in 1.20s. Direct hash probe:
base=`c2c5efe07bd7e601`, tool-section mutation=`c2c5efe07bd7e601`,
stable=True.
- **AC-2**: Changing `[project.dependencies]` or
`[build-system].requires` DOES change the computed HASH — pass.
Dependency mutation `d435cbfc2b7aca79` changed=True; build-system
requires mutation `93760788d3b9ecd3` changed=True.
- **AC-3**: Member-fork PRs produce `is_fork=false` and traverse the
trusted runtime path — pass. Policy probe with `HEAD_REPO!=BASE_REPO`
and `AUTHOR_ASSOC=MEMBER` produced `is_fork=false`; Resolve-runtime
probe with `IS_FORK=false` exported `RUNTIME_ROOT=/home/ci-runner`.
Negative probe with `AUTHOR_ASSOC=CONTRIBUTOR` produced `is_fork=true`
and isolated `RUNNER_TEMP` runtime.
- **AC-4**: `gpu-smoke` in-line `reclaim-runner-disk` does NOT invoke
atomic age-trim — pass. Composite-action run with
`SKIP_ATOMIC_AGE_TRIM=true` emitted `Skipping atomic age-trim (opted
out)`, still ran sentinel-repair on half-dead atomic subdir, and
preserved the complete atomic subdir.
- **AC-5**: `runner-maintenance.yml` daily job still performs full
atomic trim — pass. YAML probe confirmed reclaim step has
`force-reclaim=true` and `skip-atomic-age-trim` absent/false. `git diff
main...HEAD` does not modify `runner-maintenance.yml`.
- **AC-6**: Unit tests for `reclaim_cache.sh` still pass — pass.
`tests/test_reclaim_action.py` Base 13 nodes, HEAD 13 nodes, Delta 0;
all 13 sentinel-repair tests pass.

[Design][Manifest] Redesign init_dims as static_dims (docs + schema + validator) (#982)
## Summary

Complete the `static_dims` redesign (renamed from `init_dims`) for
arbitrary-rank ops in a single internally consistent PR. Scope now
covers:

1. **Docs** — authoritative spec rewrite: `docs/manifest.md` R20,
`docs/ops-design.md` `_cache_key` section,
`docs/ops-design-reference.md` Base Class Protocol + Consistency
Enforcement table.
2. **Manifest yaml** — 16 ops migrated from `init_dims: {N: {from:
"..."}}` to flat `static_dims: {N: "..."}`. LogSumExpFwdOp's multi-axis
form removed (violates new R20 single-axis rule).
3. **Validator** — `scripts/validate_manifest.py` renamed
`manifest_init_dims` → `manifest_static_dims`, reads
`sig.get("static_dims")`, updated error messages. L1 enforces
static_dims keys ⊆ `__init__` parameters.
4. **Status flips** — 13 `status: implemented` ops flipped to `status:
spec-only` with per-op comments explaining the impl/spec mismatch
(LayerNorm family × 5, BatchNorm/InstanceNorm × 3,
Softmax/LogSoftmax/LogSumExp × 3, Argmax/Argmin × 2). This is the
trust-model-prescribed response to impl divergence.
5. **PyTorch API alignment** — `dim` types include `tuple[int, ...]`;
`isinstance(dim, list)` → `(list, tuple)` throughout manifest;
LogSumExpFwdOp `shape_rules` dim-normalized.
6. **Design-first principle** — one-line statement added to `CLAUDE.md`
(always loaded). Docs focus on technical spec.

Closes #984 (absorbed). Closes #976.

#985 remains open for the Op base `_cache_key` runtime +
empty-static_dims warning.

## Test plan

- [x] `python scripts/validate_manifest.py` passes (24 pre-existing
bench-file warnings, 0 errors)
- [x] 91 validator unit tests pass (4 new `static_dims` tests)
- [x] No `init_dims` remnants anywhere: `grep -rn init_dims docs/
tileops/ scripts/ tests/` returns empty
- [x] 16 `static_dims:` entries in manifest yaml (down from 31
`init_dims` originally — 14 dim=None-supporting reduction ops correctly
had theirs removed per R20 applicability, LogSumExp removed per
single-axis rule)
- [x] `docs/manifest.md` R20 uses `static_dims` flat syntax with
single-axis reference rule, two time points + codegen pseudocode,
LinearFwdOp multi-input example, empty-legal + mandatory `_cache_key`
override (SumFwdOp example)
- [x] Design-first principle stated once in `CLAUDE.md` Project Overview
- [x] Consistency Enforcement table lists only live enforcement
(validator + runtime); deferred mechanisms tracked via issues

## Follow-up

Issues:
- #992 — dim-aware ManifestBenchmark + end-to-end roofline.vars
consumption
- #993 — retrofit 13 spec-only ops to the new static_dims / _cache_key
contract
- #994 — validator codegen parity checks for _infer_output_shapes /
_validate_dtypes

[Refactor] Rename base modules to <module>_base.py convention (#950)
## Summary

Unify base module file naming to `<module>_base.py` convention across
four modules:

- `workloads/base.py` -> `workloads/workload_base.py`
- `tileops/ops/op.py` -> `tileops/ops/op_base.py`
- `tileops/kernels/kernel.py` -> `tileops/kernels/kernel_base.py`
- `benchmarks/benchmark.py` -> `benchmarks/benchmark_base.py`

All imports, string references, and doc paths updated. No logic changes
— pure rename + import propagation.

Closes #947

## Test plan

- [x] **AC-1**: All four files renamed to <module>_base.py -- pass
- [x] **AC-2**: All imports updated, no broken references -- pass
- [x] **AC-3**: docs/testing.md path references updated -- pass
- [x] **AC-4**: Pre-commit and existing tests pass -- pass

**Test results**: 2368/2368 tests passed, 0 failed

[Refactor][Benchmark] Extract ManifestBenchmark base class and shared helpers (#915)
## Summary

Extract a generic `ManifestBenchmark` base class and shared helpers
(`roofline_vars`, `workloads_to_params`) into `benchmarks/benchmark.py`,
so manifest-driven bench files only specify the op name and baseline
function per test. This eliminates ~300 lines of duplication across 5
benchmark files.

Closes #904

## Changes

- **benchmarks/benchmark.py** — Add `ManifestBenchmark(op_name)`
subclass of `BenchmarkBase` with `roofline_vars(workload)` and
`workloads_to_params(op_name)` public helpers
-
**benchmarks/ops/bench_{softmax,reduce,argreduce,logical_reduce,vector_norm}.py**
— Refactor to use `ManifestBenchmark`, replacing 19 per-op benchmark
classes
- **scripts/validate_manifest.py** — Teach AST validator to recognize
`ManifestBenchmark` subclasses as satisfying `eval_roofline` requirement
- **tests/test_validate_manifest.py** — Add tests for indirect
bench-validator AST paths and a regression test documenting the subclass
override limitation

## Test plan

- [x] AC-1: All 5 bench files use `ManifestBenchmark` instead of per-op
classes
- [x] AC-2: `_roofline_vars` and `_workloads_to_params` exist only in
`benchmarks/benchmark.py`, not duplicated
- [x] AC-3: `pytest --collect-only` passes for all 5 bench files (63
tests collected)
- [x] AC-4: `validate_manifest.py --check-op` produces zero `[bench]`
warnings for all 19 affected ops
- [x] 89 validator tests pass, lint clean

## Follow-up

- #917 — Add import alias and attribute access support to bench AST
validator
- #918 — Type-narrow roofline_vars parameter from WorkloadBase to typed
Protocol

[Test][Softmax] Add non-aligned edge-case shapes for softmax-family ops (#914)
## Summary

Add targeted edge-case test shapes that exercise the M×N non-aligned
combination for softmax-family kernels, covering single-tile and
multi-tile (large-N) paths.

Closes #906

## Changes

**Tests** (`tests/ops/test_softmax.py`):
- 3 new shapes per fixture (SoftmaxFixture, LogSoftmaxFixture,
LogSumExpFixture):
  - `(33, 300)` fp32 — both M and N non-aligned, single-tile path
- `(33, 33000)` fp16 — both M and N non-aligned, multi-tile with masked
loads
  - `(33, 32768)` fp16 — non-aligned M with large-N tiled path

**Scripts** (`scripts/test_node_delta.py`):
- Fix base-ref collection: write temp file in original directory instead
of `/tmp/` so pytest can resolve project imports

**Foundry** (`.foundry/mold/pre-create-checks.md`):
- Add test node delta as pre-create check #3 (soft gate) with correct
`--base upstream/main` command

## Test plan

- [x] AC-1: All 126 tests pass (`pytest tests/ops/test_softmax.py`)
- [x] AC-2: New shapes exercise non-aligned M×N paths (single-tile and
multi-tile)

## Test node delta

```
File                         Base    HEAD    Delta
--------------------------------------------------
tests/ops/test_softmax.py     117     126       +9
--------------------------------------------------
TOTAL                         117     126       +9

Growth: +7.7%
```

Justification: 9 new `pytest.mark.full` nodes (3 shapes × 3 fixtures).
Each shape targets a distinct non-aligned code path not covered by
existing aligned shapes. No cross-dtype expansion (existing fixtures
already cover fp32/fp16/bf16 on aligned shapes; the non-aligned path
shares the same tiling/masked-load logic across fp16 and bf16).

## Follow-up

No follow-up issues or suggestions.

[Refactor][Manifest] Enforce status as required and validate kernel_map schema (#888)
## Summary

Update the manifest validator to enforce `status` as required and
validate `kernel_map` schema.

- `status` added to `_REQUIRED_TOP` — entries missing it produce a
schema error
- `status` must be a string (`"implemented"` or `"spec-only"`); null and
non-string values rejected
- `source.kernel_map` validated when present: must be `dict[str, str]`
- Missing `kernel_map` for `status: implemented` entries produces a
**warning** (not error) — full enforcement deferred to #887 which
populates kernel_map for all existing ops
- `_is_spec_only()` defaults to `True` on missing/non-string status
(safe for `--levels` bypass)
- Integration test validates against the real checked-in manifest

## Changed files

- `scripts/validate_manifest.py` — status required, kernel_map
validation, _is_spec_only safe default
- `tests/test_validate_manifest.py` — 9 new tests, updated helper,
integration test

## Test plan

- [x] `pytest tests/test_validate_manifest.py` — 84 passed, 1 xfailed
- [x] `python scripts/validate_manifest.py` exits 0 on real manifest (25
kernel_map warnings)
- [x] Pre-commit hooks pass

Closes #886

## Follow-up

- #887 — Populate kernel_map for all implemented ops (converts warnings
to clean pass)

No additional follow-up issues or suggestions.

[Refactor][Manifest] Rename keys to PascalCase and add ref_api field (#869)
## Summary

Rename all manifest keys from snake_case to PascalCase class names in
`{Name}{Direction}Op` format and add the required `ref_api` field to
every op entry. Validator enforces exact `cls.__name__ == manifest_key`
identity — no heuristic resolution. No op/kernel/benchmark
implementation code is modified.

**Note**: After this PR merges, benchmark callers that use snake_case op
names (e.g. `load_workloads("rmsnorm_fwd")`) will break. PR-B (#866)
fixes all callers as part of the class rename.

Closes #865

## Test plan

- [x] All manifest keys are PascalCase class names in
`{Name}{Direction}Op` format
- [x] `ref_api` field required for all ops (`"none"` when no external
API counterpart)
- [x] Validator L0 schema enforces `ref_api` as required string
- [x] Validator requires exact `cls.__name__ == manifest_key` — no
single-candidate bypass, no heuristic fallback
- [x] No changes to any file under `tileops/ops/`, `tileops/kernels/`,
or `benchmarks/`
- [x] Integration test `xfail` until PR-B renames Op classes

## Changed files

- `tileops/ops_manifest.yaml` — renamed all 52 keys, added `ref_api` to
every entry
- `tileops/manifest.py` — canonical PascalCase keys only (no legacy
alias resolution)
- `scripts/validate_manifest.py` — `ref_api` required in L0 schema,
exact class-name identity enforcement
- `tests/test_ops_manifest.py` — updated test fixtures, canonical key
tests
- `tests/test_validate_manifest.py` — updated validator tests,
exact-match enforcement tests

[Doc][Manifest] Clarify same_as(ref) as identity constraint with validator enforcement (#864)
## Summary

Clarify \`same_as(ref)\` as a dtype-only identity constraint in manifest
spec, and add validator enforcement.

**Docs:**
- \`docs/manifest.md\`: R3/R3a define \`same_as(ref)\` as exact dtype
identity (not "dependent types"). R5/R8 clarify \`same_as\` is
dtype-only — shape must be explicitly declared. R13 status default
changed to \`spec-only\`. Overall doc reduced by ~27% (470→342 lines).
- \`.claude/domain-rules/manifest-spec.md\`: matching updates —
\`same_as\` dtype identity, shape explicit, status default
\`spec-only\`.

**Validator:**
- \`_check_dtype_combos_same_as_identity()\`: enforces that
\`dtype_combos\` entries assign the same dtype to \`same_as\`-bound
tensors. Rejects partial combos where a bound tensor appears without its
reference.
- \`_is_spec_only()\`: defaults to \`spec-only\` when \`status\` is
absent, matching R13.

**Tests:** 5 new test cases — dtype_combos pass, mismatch, multi-binding
mismatch, partial-combo rejection, missing-status default.

Closes #863

## Changes

- \`docs/manifest.md\` — rewritten: concise, no "dependent types",
\`same_as\` dtype-only, status default spec-only
- \`.claude/domain-rules/manifest-spec.md\` — matching rule updates
- \`scripts/validate_manifest.py\` — \`_build_same_as_map()\`,
\`_check_dtype_combos_same_as_identity()\`, \`_is_spec_only()\` default
fix
- \`tests/test_validate_manifest.py\` — 5 new tests (81 total, all pass)

## Test plan

- [x] AC-1: \`docs/manifest.md\` R3/R3a explicitly defines
\`same_as(ref)\` as dtype identity constraint
- [x] AC-2: Validator flags \`dtype_combos\` with mismatched or partial
\`same_as\`-bound entries
- [x] AC-3: Full manifest validation passes (\`python
scripts/validate_manifest.py\` → 0 errors)

## Follow-up

No follow-up issues or suggestions.

[Refactor][Validator] Deduplicate PascalCase resolution loops in _resolve_op_class (#836)
## Summary

Consolidates the duplicated resolution heuristics in `_resolve_op_class`
into a single strategy loop and adds ambiguity detection to all matching
stages (not just the terminal fallback).

- Three separate PascalCase loops (stripped_pascal, full_pascal,
suffix_fwd_bwd) replaced with single `for`-loop over an ordered
strategies list
- Suffix matching (`_fwd`/`_bwd`) now emits an ambiguity warning when
multiple candidates match, consistent with the pattern established in PR
#830
- One new test (`test_suffix_match_ambiguity_emits_warning`) covers the
multi-candidate suffix case

Closes #811

## Acceptance Criteria

| ID | Criterion | Status |
|----|-----------|--------|
| AC-1 | Single resolution loop replaces the duplicated PascalCase loops
| PASS |
| AC-2 | _fwd/_bwd suffix matching emits ambiguity warning when multiple
candidates match | PASS |
| AC-3 | All existing TestResolveOpClass tests pass unchanged | PASS |
| AC-4 | New test covers suffix-match ambiguity (multiple fwd
candidates) | PASS |
| AC-5 | Full manifest validation passes | PASS |

## Test plan

- [x] 25 TestResolveOpClass tests pass (24 pre-existing + 1 new) — 2.93s
- [x] Full test suite: 75 passed, 0 failed
- [x] `python scripts/validate_manifest.py` — all manifest checks passed
- [x] pre-commit lint passes (ruff, codespell, mdformat)

## Follow-up

No follow-up issues or suggestions.

[Fix][Validator] Emit warning on ambiguous op class resolution instead of silent fallback (#830)
## Summary

When `_resolve_op_class` finds multiple candidate classes but no naming
heuristic matches, it previously fell back silently to `candidates[0]`
(alphabetical order). This could produce wrong validation results
without any diagnostic.

This PR replaces the silent fallback with a `UserWarning` that
identifies the op name, all candidate class names, and the file path,
then returns an unresolved result (`cls=None`) so the caller can handle
it explicitly.

Closes #810

## Test plan

- [x] AC-1: When all heuristics fail, a warning or error is emitted
identifying the ambiguous resolution
- [x] AC-2: Full manifest validation passes (no existing ops broken) —
`python scripts/validate_manifest.py` -> All checks passed
- [x] AC-3: Unit test covers the ambiguous-fallback code path —
`test_ambiguous_fallback_returns_none_with_warning` added

**Test results**: 79 tests passed, 0 failed

## Follow-up

- #811 — Consolidate resolution heuristics + fix `_fwd`/`_bwd`
suffix-match silent fallback

Suggestions: strengthen ambiguous-fallback test to match full diagnostic
fields (op_name, candidate_names, op_file)

[Fix][Validator] Resolve op classes in multi-class files by PascalCase convention (#807)
## Summary

Fix `_resolve_op_class` to correctly resolve op names to classes when
source files contain multiple Op classes (e.g., `reduce.py` with 8 ops).
The previous substring heuristic (`all parts in cls_lower`) was too
permissive — `var_fwd` matched `AmaxOp` instead of `VarOp` because no
class contained `"fwd"`, and the alphabetical fallback picked the wrong
candidate.

Closes #803

## Changes

### Resolver heuristic rewrite (`scripts/validate_manifest.py`)
- **Removed** the loose substring-based multi-candidate heuristic
(`all(p in cls_lower for p in parts)`)
- **Added** exact PascalCase match as the primary multi-candidate
strategy: strip `_fwd`/`_bwd` suffix, convert remainder to PascalCase +
`"Op"` (e.g., `var_fwd` → `VarOp`, `var_mean_fwd` → `VarMeanOp`)
- **Added** full-name PascalCase fallback for Fwd/Bwd-suffixed class
naming conventions (e.g., `batchnorm_fwd` → `BatchNormFwdOp`)
- Retained suffix matching (`fwd`/`bwd` in class name) as final fallback

### Test coverage (`tests/test_validate_manifest.py`)
- Added `TestResolveOpClass` class with 21 test cases:
- 8 parametrized tests for `reduce.py` multi-class resolution (SumOp,
MeanOp, AmaxOp, AminOp, ProdOp, VarOp, StdOp, VarMeanOp)
- 11 parametrized tests for all single-file reduction ops (argmax,
argmin, all, any, count_nonzero, l1_norm, l2_norm, inf_norm, softmax,
log_softmax, logsumexp)
- Single-class file resolution, import error handling, no-op-class
handling

### Review fixes
- Removed duplicate test method flagged by Copilot review
- Fixed misleading comment example (`"batchnorm_fwd" → "BatchnormFwdOp"`
→ `"sum_fwd" → "SumFwdOp"`)

## Test plan

- [x] **AC-1**: `_resolve_op_class` returns correct class for all 19
reduction ops (8 multi-class in `reduce.py` + 11 single-file) — verified
by parametrized tests
- [x] **AC-2**: Existing resolver behavior unchanged for single-class
files and Fwd/Bwd-suffixed classes — verified by
`test_single_class_file_resolves`
- [x] **AC-3**: Unit tests cover multi-class resolution scenarios — 21
test cases in `TestResolveOpClass`

**Test results:** 72 passed, 0 failed

## Follow-up

- #810 — Emit warning on silent `candidates[0]` fallback
- #811 — Deduplicate PascalCase resolution loops

[Feat][Manifest] Add --check-op flag for spec-only validation override (#780)
## Summary

Add a `--check-op <name>` CLI flag to the manifest validator that forces
all validation levels (L0-L4) on the specified op, bypassing the
`status: spec-only` gate. Default (unflagged) behavior is unchanged.

Closes #779

## Test plan

| AC | Description | Status |
|----|-------------|--------|
| AC-1 | `python scripts/validate_manifest.py --check-op softmax_fwd`
runs L0-L4 on `softmax_fwd` even when `status: spec-only` | pass |
| AC-2 | `python scripts/validate_manifest.py` (without flag) behavior
unchanged -- spec-only ops still skip L1-L4 | pass |
| AC-3 | Unit test covers both behaviors (with/without flag, nonexistent
op, single-op scoping, variant_of regression) | pass |
| AC-4 | Modified files pass existing tests (45/45 passed) | pass |

## Validation

- 45 tests passed, 0 failed
- Pre-commit hooks pass (ruff, codespell, mdformat, gitleaks)
- Files changed: `scripts/validate_manifest.py`,
`tests/test_validate_manifest.py`

[Chore][Manifest] Strict L1 signature: check __init__() + forward() param union (#768)
## Summary

Make L1 validator strictly require that all manifest-declared params for
`status: implemented` ops appear in the Op's `__init__()` + `forward()`
union signature. This ensures manifest declarations stay in sync with
actual code interfaces.

- Update `check_l1_signature()` to inspect both `__init__` and `forward`
param names
- Audit and fix all 23 implemented ops that failed strict L1
- Update `docs/manifest.md` L1 description to reflect the stricter rule

Closes #765

## Test plan

- [x] **AC-1**: check_l1_signature() checks manifest params against
__init__ + forward union, not just forward
- [x] **AC-2**: All status: implemented ops pass strict L1 in CI
- [x] **AC-3**: docs/manifest.md L1 description updated to reflect
strict matching rule
- [x] **AC-4**: Modified files pass existing tests

**Test results**: 47/47 passed (24 validator + 23 manifest), 0 failed.

[Fix][Benchmark] Add serial validation to correct noisy autotune configs (#773)
## Summary

- Parallel warmup (`-n 8`) causes autotuner to select suboptimal configs
due to GPU contention noise, which get cached and reused by serial
benchmarks
- Add a Phase 2 serial validation pass in `warmup_kernel_cache.py` that
re-tunes on a quiet GPU with `.so` cache hits (compilation instant, only
profiling re-runs)
- Add autotune config column to `BenchmarkReport` so nightly reports
show which config was selected

## How it works

| Phase | Compilation cache (`.so`) | Autotune cache (`best_config`) |
|---|---|---|
| Phase 1: parallel warmup (`-n 8`) | Write (parallel, fast) | Write
(noisy — GPU contention) |
| Phase 2: serial validation | Read (cache hit, instant) | Overwrite
(accurate — exclusive GPU) |

`conftest_warmup.py` supports a new `TILEOPS_WARMUP_VALIDATE=1` mode
that patches `AutoTuner._load_result_from_disk` to return `None`,
forcing re-tune while preserving `.so` cache.

## Evidence

Same kernel (`avg_pool2d vision-3x3-s2`) selects different configs under
contention vs serial:
- **Parallel (8 workers)**: `{'block_m': 128, 'block_c': 64, 'threads':
256}`
- **Serial (3/3 runs consistent)**: `{'block_m': 64, 'block_c': 32,
'threads': 256}`

Fixes #772

## Test plan
- [x] Full warmup + validation pass completes on all benchmark files
- [x] Serial validation correctly overwrites noisy autotune cache
- [x] `BenchmarkReport` includes config column for tileops entries
- [x] Verified on H200 with `tileops-runner:latest`

[Chore][Testing] Add unit-test policy and test node growth detection script (#761)
## Summary

Define a unit-test policy for operator tests and provide a local script
(`scripts/test_node_delta.py`) that reports test node count delta for
touched files in a PR, making growth visible and justifiable.

Closes #760

## Changes

**M1 — Unit-test policy**
- Added Unit-Test Policy section to `docs/testing.md` covering: allowed
UT purposes, dtype risk class rule, shape coverage rule, manifest
separation, growth justification
- Added `.claude/rules/testing-budget.md` with concise agent-enforceable
version
- Verified policy is consistent with existing smoke/full tier system in
`tests/conftest.py`

**M2 — Growth-detection script**
- Created `scripts/test_node_delta.py` that compares test node counts
between current branch and main
- Added usage instructions to `docs/testing.md`
- Added note in `.claude/rules/testing-budget.md` about running script
and justifying growth

## Test plan

- [x] **AC-1-1**: docs/testing.md contains a Unit-Test Policy section
with dtype risk class, shape coverage, manifest separation, and growth
justification rules
- [x] **AC-1-2**: .claude/rules/testing-budget.md exists and is loadable
by Claude Code
- [x] **AC-1-3**: Policy does not contradict existing tier enforcement
in tests/conftest.py
- [x] **AC-2-1**: Script runs successfully on the current repo and
reports node counts for at least 3 existing test files
- [x] **AC-2-2**: Script correctly detects delta when a test file has
more nodes than its main branch version
- [x] **AC-2-3**: Script exits 0 regardless of delta (non-blocking)
- [x] **AC-2-4**: Script handles new test files (no main branch version)
without error
- [x] **AC-2-5**: docs/testing.md documents how to run the script

[Chore][Manifest] Add manifest validator with CI integration (#745)
Closes #738

## Summary

- Add `scripts/validate_manifest.py` implementing manifest validation
for schema, `Op.forward()` signature consistency, `shape_rules` syntax,
dtype conformance, and benchmark manifest usage
- Integrate the validator into the preflight workflow with a dedicated
`validate-manifest` job
- Add MoE manifest entries and migrate the MoE benchmarks in this PR to
manifest-driven workloads via `load_workloads()` and `eval_roofline()`
- Make benchmark strictness explicit with `source.bench_manifest_driven:
true` for migrated entries, while leaving legacy non-migrated benchmarks
as warnings
- Clarify in `docs/manifest.md` that `workloads` are for
nightly/performance benchmark coverage only, not unit-test coverage
- Add merge-ready validator coverage in
`tests/test_validate_manifest.py`
- Add a developer-agent rule in `.claude/rules/manifest-validator.md`
forbidding validator edits as a way to bypass manifest constraints

## Test plan

- [x] pre-commit passed (all hooks green)
- [x] `pytest -q tests/test_validate_manifest.py` -- 20 passed
- [x] `pytest -q tests/ops/test_moe_permute.py` -- 9 passed
- [x] `python scripts/validate_manifest.py` passes on current codebase
(exit 0)

## Structural Readiness

SKIP -- primary deliverable is infrastructure (manifest validator + CI
integration), not a new kernel/op.

## Additional context

**Validation checks:**
- **Schema**: YAML structure, required fields, and field types
- **Signature**: `Op.forward()` parameters must match manifest inputs,
plus any accepted manifest-declared runtime params, in order
- **Shape**: `shape_rules` must parse as valid Python expressions
- **Dtype**: manifest dtype strings and workload dtypes must be
recognized
- **Benchmark**: migrated benchmark files must import and call
`load_workloads` / `eval_roofline` with the correct op name

**Current enforcement model:**
- `status: spec-only` entries receive schema-only validation
- L4 benchmark enforcement is hard-fail only for entries that explicitly
opt in with `source.bench_manifest_driven: true`
- Legacy benchmark files that have not yet migrated remain warnings, not
CI failures

[Bench] Add FA3/FlashInfer baselines across all attention benchmarks (#734)
## Summary

- **Fix FA3 import**: `bench_mha.py` used `import flash_attn_interface`
(not installed), silently falling back to `torch-sdpa`. Fixed to `from
flash_attn import flash_attn_func`.
- **Add FA3 baselines**: `bench_mha_decode`, `bench_gqa_decode`,
`bench_mha_decode_paged`, `bench_gqa_decode_paged` — previously only had
`torch-sdpa`/`torch-ref`.
- **Add FlashInfer baselines**: All 8 attention benchmark files now
include FlashInfer baselines using batched APIs
(`BatchPrefillWithRaggedKVCacheWrapper` /
`BatchDecodeWithPagedKVCacheWrapper`).
- **Fairness fix**: Replaced per-batch `single_prefill_with_kv_cache`
loops with batched wrappers. CUPTI sums all kernel durations — per-batch
loops launch B separate kernels that can't exploit cross-batch
parallelism.
- **bf16 fix**: FlashInfer `wrapper.plan()` defaults
`q_data_type='float16'`. Added explicit `q_data_type=q.dtype` to all
plan() calls. Note: the decode wrapper's `data_type` param does NOT
propagate to `q_data_type`.
- **Multi-baseline report**: `conftest.py` writes all baselines to JUnit
XML with tag-prefixed properties. `nightly_report.py` parses and
displays multiple baselines per config.

## Scope

| File | Changes |
|:-----|:--------|
| `bench_mha.py` | Fix FA3 import + add FlashInfer fwd |
| `bench_mha_decode.py` | Add FA3 + FlashInfer |
| `bench_gqa.py` | FlashInfer: per-batch loop to batched API |
| `bench_gqa_decode.py` | Add FA3 + FlashInfer |
| `bench_mha_decode_paged.py` | Add FA3 (page>=256) + FlashInfer paged |
| `bench_gqa_decode_paged.py` | Add FA3 (page>=256) + FlashInfer paged |
| `bench_gqa_sliding_window_fwd.py` | Add FlashInfer (wr<0 only) |
| `bench_gqa_sliding_window_varlen_fwd.py` | Add FlashInfer ragged (wr<0
only) |
| `conftest.py` | Multi-baseline JUnit XML properties |
| `nightly_report.py` | Multi-baseline parsing, display, alerts |

## Skipped (expected)

- **bwd**: FlashInfer has no backward API
- **window_right >= 0**: FlashInfer only supports `window_left`
- **FA3 paged with page_size < 256**: FA3 requires page_block_size
multiple of 256

## Test plan

- [x] 36/36 benchmarks passed in `tileops-runner:latest` on H200 (GPU1,
1830 MHz locked)
- [x] bf16 configs verified: FlashInfer data present for all non-bwd,
non-window_right configs
- [x] Multi-baseline XML properties correctly written (fa3 + flashinfer
tags with latency/ratio)
- [ ] Nightly CI should now report fa3 and flashinfer baselines across
all attention ops

[CI] Fix warmup OOM, enable autotuner caching, skip baselines (#685)
## Summary

Three fixes to the nightly warmup phase:

1. **Fix GPU OOM causing warmup to hang** — pytest-xdist workers
accumulated GPU memory over their lifetime; idle workers held ~140GB
while the last worker starved and hung at 98%. Added `gc.collect()` +
`torch.cuda.empty_cache()` after each test.

2. **Enable autotuner result caching** — Removed
`TILELANG_AUTO_TUNING_DISABLE_CACHE=1` and the `do_bench` mock patch.
Warmup now runs real GPU profiling and saves `best_config.json` to disk.
Subsequent warmup and benchmark runs hit the autotuner cache (~2ms per
kernel instead of minutes).

3. **Skip baseline profiling during warmup** — Patched
`BenchmarkBase.profile` to return dummy results for non-Op functors
(torch-cublas, FA3, etc.). Baseline measurements serve no purpose during
warmup.

Also bumped default pytest-xdist workers from 8 to 16.

**Result**: warmup dropped from 38min (hanging at 98%) to 9min (912/912
passed).

## Changes

- `scripts/warmup_kernel_cache.py` — Remove
`TILELANG_AUTO_TUNING_DISABLE_CACHE=1`, default `-n 16`
- `scripts/conftest_warmup.py` — Remove `do_bench` mock, add GPU memory
cleanup hook, add baseline skip
- `.github/workflows/nightly.yml` — Bump warmup to `-n 16`

## Test plan

- [x] Warmup completes without OOM (912/912 passed, GPU memory stable at
~20-30GB)
- [x] Warmup time: 38min (hanging) → 9min with caches warm
- [x] Autotuner cache populated (best_config.json written to disk)
- [ ] Verify all 4 nightly phases complete via `workflow_dispatch`

[Fix][CI] Install external baseline libraries in nightly benchmarks (#673)
## Summary

Closes #670.

Nightly benchmarks were missing external baseline libraries (flash-attn,
fla, vllm, sgl-kernel, native_sparse_attention), causing benchmarks to
fall back to slow PyTorch reference implementations and inflating
speedup numbers.

- Add `bench` extras group in `pyproject.toml` with pinned versions
(flash-attn 2.8.3, flash-linear-attention 0.4.2, vllm 0.18.0, sgl-kernel
0.3.21)
- Relax torch upper bound from `<2.10.0` to `<2.11.0` for vllm 0.18.0
compatibility (tilelang 0.1.8 verified compatible with torch 2.10.0)
- Add "Install benchmark baseline libraries" step in nightly Phase 1
(cache-warmup) and Phase 2 (benchmark), always executed regardless of
`VENV_REUSED` — pip is idempotent and completes in seconds when versions
are unchanged
- Exclude `bench` group from `dep_hash.py` so bench version bumps do not
trigger full venv rebuilds or invalidate kernel compile caches
- Pin `native_sparse_attention` to commit `bd67af59` (not on PyPI);
gracefully skip on GitHub network errors
- Add `install-bench` Makefile target for local development

## Test plan

- [x] `python scripts/dep_hash.py` produces identical hash before and
after adding `bench` group (confirms exclusion works)
- [x] `pip install --dry-run` resolves all bench deps + core deps
without conflicts (torch 2.10.0, tilelang 0.1.8, vllm 0.18.0, flash-attn
2.8.3, flash-linear-attention 0.4.2, sgl-kernel 0.3.21)
- [ ] Next nightly run should show benchmarks using real baselines (fa3,
fla, etc.) instead of torch fallbacks

[Fix][Bench] Fix 11 nightly benchmark failures and report omission (#635)
## Summary

- **Backward baselines fail under `no_grad()`**:
`BenchmarkBase.profile()` wraps calls in `torch.no_grad()`, breaking
autograd-based torch SDPA backward baselines when FA3 is unavailable.
Fixed by adding `@torch.enable_grad()` to baseline functions in
`bench_engram_bwd`, `bench_gqa`, and `bench_mha`.
- **mha_decode `result_idx` OOB**: When autotune selects `num_split>1`
but `seqlen_kv` is too small, the runtime fallback to `num_split=1`
recompiles `mha_decode_no_split` (5 params) with `out_idx=[7]` (resolved
from the 8-param split function). Fixed by guarding the split kernel's
`logsum` division against zero (empty splits) and removing the runtime
`num_split` fallback.
- **Nightly report silently drops benchmark failures**:
`aggregate_bench_results()` filters `outcome != "passed"`, so failed
benchmarks never appear. Added `collect_bench_failures()`, a "Benchmark
Failures" section, summary row, and health indicator integration.

Closes #634

## Test plan

- [x] `bench_engram_bwd` — all 4 cases pass locally (no FA3)

[Fix][Bench] Fix nightly report: broken summary, formatting, missing baselines (#626)
## Summary

Closes #625

Four fixes for the nightly report pipeline:

### A. Remove broken benchmark step summary
The Phase 2 bash XML parser failed on single-line XML (`<testsuites>`
and `<testsuite>` on same line → regex never matched → all counters 0).
Removed entirely since Phase 3 nightly report already covers this.

### B. Improve nightly report aesthetics
- Emoji status indicators, color-coded ratio circles
- `<details>` collapsible sections for long tables (120+ correctness,
600+ benchmark rows)
- Right-aligned numeric columns, bold Op names, `code` module paths
- Emoji unicode centralized as module-level constants

### C. Annotate strategy benchmark entries
54 `test_fused_gated_strategy_bench` entries had blank Via column. Added
`tileops_variant` property in conftest → report shows `strategy: direct`
/ `strategy: explicit_parallel`.

### D. Add missing baseline to `bench_engram_bwd.py`
4 entries had no baseline at all. Added `test.ref_program` with
`tag="torch"`.

[CI] Add Op-level nightly report with correctness, performance, and regression tracking (#620)
## Summary

- Inject Op metadata (class name, module path, error metrics, perf data)
into pytest JUnit XML `<property>` elements
- Add `scripts/nightly_report.py` to generate an Op-granularity markdown
report from JUnit XML
- Integrate report generation into nightly CI workflow with
`perf_history.json` artifact for 14-day regression tracking

## Changes

### Data collection (pytest side)
- **`tests/test_base.py`**: `check()` now records
`op.__class__.__name__`, `op.__class__.__module__`, `max_abs_err` via
logging + thread-local
- **`tests/conftest.py`**: `pytest_runtest_call` hookwrapper writes Op
info to `item.user_properties` → JUnit XML `<property>`
- **`benchmarks/benchmark.py`**: `record()` accepts Op objects
(backward-compatible), accumulates tileops + baseline data
- **`benchmarks/conftest.py`**: hookwrapper writes perf data + baseline
ratio to `item.user_properties`
- **`benchmarks/ops/bench_*.py`** (52 files): `record("name", ...)` →
`record(op, ...)`

### Report generation
- **`scripts/nightly_report.py`**: Parses JUnit XML, aggregates by Op,
detects regressions vs 14-day best, baseline alerts (ratio < 80%),
generates markdown
- **`.github/workflows/nightly.yml`**: Downloads artifacts, runs report
script, posts to `$GITHUB_STEP_SUMMARY`, manages `perf_history.json`
artifact

### JUnit XML output format
```xml
<!-- Correctness test -->
<testcase name="test_gqa_fwd[smoke-fwd-fp16]">

[BugFix][CI] Fix warmup error handling, monkeypatch cleanup, and portable cache paths (#548)
## Summary

- Fix warmup script to propagate infrastructure errors (pytest exit
codes 2-5) while still tolerating test failures (exit code 1)
- Restore original `ThreadPoolExecutor` in `pytest_unconfigure` to
prevent global state leaks
- Replace all hardcoded `/home/ci-runner/` paths with `${HOME}/` for
runner portability

Closes #545
Closes #546

## Changes

### 1. Warmup exit code handling (#545)

```diff
- sys.exit(0)  # unconditional
+ if exit_code in (0, 1):
+     sys.exit(0)  # tests passed or failed — compilation succeeded
+ else:
+     sys.exit(exit_code)  # infrastructure error — surface it
```

| Exit Code | Meaning | Before | After |
|-----------|---------|--------|-------|
| 0 | All passed | exit 0 | exit 0 |
| 1 | Test failures | exit 0 | exit 0 (compilation still worked) |
| 2 | Interrupted / bad args | exit 0 (swallowed) | **exit 2** |
| 3 | Internal error | exit 0 (swallowed) | **exit 3** |
| 4 | Usage error | exit 0 (swallowed) | **exit 4** |
| 5 | No tests collected | exit 0 (swallowed) | **exit 5** |

### 2. ThreadPoolExecutor cleanup (#545)

```diff
  def pytest_unconfigure(config):
      patcher = getattr(config, "_warmup_patcher", None)
      if patcher is not None:
          patcher.stop()
+
+     orig_pool = getattr(config, "_warmup_orig_pool", None)
+     if orig_pool is not None:
+         concurrent.futures.ThreadPoolExecutor = orig_pool
```

### 3. Portable cache paths (#546)

```diff
- TILELANG_CACHE_DIR="/home/ci-runner/.tilelang/cache"
+ TILELANG_CACHE_DIR="${HOME}/.tilelang/cache"
```

Applied to all 4 jobs (cache-warmup, benchmark, op_test, packaging). 14
occurrences replaced.

## Test plan

- [ ] Verify warmup exits non-zero when pytest encounters infrastructure
errors
- [ ] Verify warmup exits 0 when tests fail but compilation completed
- [ ] Verify no hardcoded `/home/ci-runner/` paths remain
- [ ] Verify cache paths resolve correctly on CI runner

[CI] Separate kernel compilation from profiling and parallelize compilation in nightly (#542)
## Summary

- Add a `cache-warmup` job to the nightly workflow that pre-compiles all
benchmark kernel variants before the benchmark job runs, separating
compilation (CPU-bound) from profiling (GPU-bound)
- Fix venv cache hash to only include dependency fields from
`pyproject.toml`, preventing unnecessary rebuilds from linting/style
config changes
- Restructure nightly job flow: `cache-warmup → benchmark → op_test →
packaging`

## Background

In [nightly run
#23161046010](https://github.com/tile-ai/TileOPs/actions/runs/23161046010),
the benchmark job hit the 90-minute timeout at only 48% progress.
Analysis showed ~80-90% of the time was spent on kernel compilation
(`g++`/`cc1plus` still running at cancellation), not GPU profiling.

Root causes:
1. **Venv prefix rename** in #530 caused `VENV_REUSED=false` → pip
reinstalled tilelang → `libtilelang.so` mtime changed → **all kernel
caches invalidated** (tilelang cache keys include `.so` mtime)
2. **`tune=True` benchmarks** (GEMM 288 configs, MHA, etc.) compile
hundreds of kernel variants through TIR → CUDA → nvcc/g++ pipeline, all
serially during pytest execution

## Changes

### 1. Kernel cache warmup (`scripts/warmup_kernel_cache.py`)

- Monkeypatches `tilelang.profiler.do_bench` to return dummy value →
compilation happens normally, GPU profiling skipped
- Sets `TILELANG_AUTO_TUNING_DISABLE_CACHE=1` → dummy results not
persisted to autotuner cache
- Two levels of parallelism:
- **pytest-xdist** (`-n 8`): 8 worker processes running different
benchmark test cases simultaneously
- **ThreadPoolExecutor** (`--max-workers 64`): within each `tune=True`
op, autotuner compiles up to 64 config variants in parallel
- **Zero maintenance**: new ops with benchmarks are automatically
discovered and pre-compiled
- Supports `--shard`/`--total-shards` for future parallelization across
runners

### 2. Venv hash fix (Closes #540)

```diff
- sha256sum pyproject.toml
+ python3 scripts/dep_hash.py  # hashes only dependencies, optional-deps, requires-python, build-requires
```

Applied to all 4 jobs (cache-warmup, benchmark, op_test, packaging).
Changes to ruff rules, codespell config, pytest markers etc. no longer
trigger venv rebuild.

### 3. Job dependency restructure & timeout adjustments

```
cache-warmup (60 min) → benchmark (120 min) → op_test (180 min) → packaging
```

GPU jobs (benchmark, op_test) remain serial for measurement accuracy.
Compilation cost is moved to the warmup phase.

## Local benchmark results (H200)

Tested on a clean tilelang cache to simulate a worst-case cold start:

| Phase | Duration |
|-------|----------|
| Warmup (n=8, --max-workers 64, cold cache) | 24 min |
| Benchmark (warm cache, first run) | 73 min |
| **Total** | **97 min** |

### Comparison with the previous approach

| | Before | After (this PR) |
|---|---|---|
| Compilation | Serial, interleaved with profiling. 90 min timeout at
48% — estimated **3h+** to complete | Warmup job: 8 pytest workers × 64
compile threads, **24 min** |
| Benchmark | Blocked behind compilation, never finished | All kernels
pre-compiled, **73 min** (first run) |
| **Total** | **> 3h (timeout, incomplete)** | **97 min (complete)** |

### Expected time in subsequent nightly runs (steady state)

Both the kernel cache and autotuner result cache are stored in
persistent directories on the self-hosted runner (`TILELANG_CACHE_DIR`).
As long as the venv is not rebuilt (i.e., dependencies unchanged), these
caches persist across nightly runs:

| Phase | First run (cold cache) | Subsequent runs (warm cache) |
|-------|----------------------|---------------------------|
| Warmup | 24 min (full compilation) | **~2-3 min** (all cache hits, no
actual compilation) |
| Benchmark | 73 min (autotuner profiles all configs) | **~30-40 min**
(autotuner cache hit → skip profiling 288 configs per op, only benchmark
the best config) |
| **Total** | **97 min** | **~35-45 min** |

### Additional notes

- **Deepseek kernel issues**: Several Deepseek-related kernels currently
have compilation or runtime issues (6 consecutive failures at ~48%
progress). Once fixed, the time spent on their failed compilation/retry
will be recovered.
- **Warmup failures are non-blocking**: The warmup job uses
`continue-on-error: true` and always exits 0. Any kernel that fails to
compile during warmup will simply be compiled on-demand during the
benchmark job (same behavior as before this PR).

## Test plan

- [x] Verify warmup script compiles kernels and populates cache (local
H200)
- [x] Verify benchmark completes with warm cache (local H200, 73 min)
- [x] Verify n=8 xdist parallelism works (24 min vs n=4 at 32 min)
- [ ] Verify nightly completes within timeout on CI runner
- [ ] Verify venv hash is stable across non-dependency pyproject.toml
