feat(sweeper): add on_candidate callback to Sweeper.run - #319
Conversation
Sweeper.run() currently exposes on_round for round-level progress, but nothing fires per candidate outcome. DEP ai-dynamo/dynamo#15073 needs this granularity for its search_resolved event (per-candidate materialization outcome, not just per-round), and no such hook exists today for any caller to build on. on_candidate is invoked once per recorded CandidateRecord (feasible, infeasible, unsupported, timed-out, or failed), at the same call site _record() already uses for the existing resource_aware checkpoint() call. Purely additive: defaults to None, zero behavior change for every existing caller.

One P2 from an exact-head behavioral review, reproduced with a real spawned ProcessPoolExecutor and synthetic runners.
on_candidate now receives a deep copy of each CandidateRecord instead of the live ledger entry, so callback mutations can't affect the SweepResult that gets built from the same ledger. The docstring is updated to document all six outcomes on_candidate can report and to spell out the detach guarantee. evaluate_waves() now drains a second, non-blocking wait() immediately after resuming from each yield, before checking the deadline. Without it, a sibling future that completed while the caller's on_candidate callback was running (which can take arbitrarily long, since the generator is suspended at the yield for its duration) was misreported as timed out instead of as its real outcome. Adds a regression test that reproduces the race deterministically via a fake wait()/clock. Addresses review comments from coderabbitai and tedzhouhk on ai-dynamo#319.

The previous fix drained one extra time after the first wait() to catch a sibling that finished while the caller's on_candidate callback was running. With three or more active futures that's not enough: a second sibling can finish while the caller is still handling the first extra-drained yield. Loop the non-blocking poll-and-drain until a poll comes back empty, rather than doing it once, before checking pressure or the deadline. Also fixes the existing regression test's fake wait()/Future timing, which asserted a callback-pause timeline while pre-resolving both futures up front and contradicting Future.done() semantics in the fake wait(). fake_wait now checks .done() directly, and each future's result is set at the point in time the test claims it completes. Adds a three-candidate regression case for the multi-sibling drain gap above. Addresses coderabbitai's follow-up review on ai-dynamo#319.

Looks good. Just one question.
on_candidate now receives a deep copy of each CandidateRecord instead of the live ledger entry, so callback mutations can't affect the SweepResult that gets built from the same ledger. The docstring is updated to document all six outcomes on_candidate can report and to spell out the detach guarantee. evaluate_waves() now drains a second, non-blocking wait() immediately after resuming from each yield, before checking the deadline. Without it, a sibling future that completed while the caller's on_candidate callback was running (which can take arbitrarily long, since the generator is suspended at the yield for its duration) was misreported as timed out instead of as its real outcome. Adds a regression test that reproduces the race deterministically via a fake wait()/clock. Addresses review comments from coderabbitai and tedzhouhk on #319.
The previous fix drained one extra time after the first wait() to catch a sibling that finished while the caller's on_candidate callback was running. With three or more active futures that's not enough: a second sibling can finish while the caller is still handling the first extra-drained yield. Loop the non-blocking poll-and-drain until a poll comes back empty, rather than doing it once, before checking pressure or the deadline. Also fixes the existing regression test's fake wait()/Future timing, which asserted a callback-pause timeline while pre-resolving both futures up front and contradicting Future.done() semantics in the fake wait(). fake_wait now checks .done() directly, and each future's result is set at the point in time the test claims it completes. Adds a three-candidate regression case for the multi-sibling drain gap above. Addresses coderabbitai's follow-up review on #319.

… format Address coderabbitai review on ai-dynamo#319: the existing on_candidate test only inspected callback records, so it would pass even if the callback received the ledger record directly. Mutate a nested field on the callback's record and assert the corresponding SweepResult.candidates entry is unaffected. Also reformats tests/test_resource_scheduler.py per ruff-format (--config python/aisimulate/pyproject.toml, line-length 120), fixing the CI failure from lines wrapped at 88 columns in an earlier local edit.

* feat(cli): prototype recommendation output adapters Signed-off-by: Dr. Stefan Schimanski <stefan.schimanski@gmail.com> * feat(sweeper): add on_candidate callback to Sweeper.run Sweeper.run() currently exposes on_round for round-level progress, but nothing fires per candidate outcome. DEP ai-dynamo/dynamo#15073 needs this granularity for its search_resolved event (per-candidate materialization outcome, not just per-round), and no such hook exists today for any caller to build on. on_candidate is invoked once per recorded CandidateRecord (feasible, infeasible, unsupported, timed-out, or failed), at the same call site _record() already uses for the existing resource_aware checkpoint() call.

Brings in the FPM decoupling / self-service onboarding stack (ai-dynamo#238, ai-dynamo#248, ai-dynamo#347), the output adapters (ai-dynamo#334) and the CI changes (ai-dynamo#349, ai-dynamo#351, ai-dynamo#353, ai-dynamo#354, ai-dynamo#330, ai-dynamo#319). Conflict resolutions: - ENGINE_SPEC_SCHEMA_VERSION: upstream claimed 25 for the FPM decoupling selector; decode CP is renumbered to 26 (positional dcp_size tails on the attention / MLA / DSA ops). Stale-payload loops reject 20..25; the 25 payload keeps the selector like the decoupling branch's 21. - cp_size: upstream added a CP1-only `cp_size` to compile_engine, estimate_kv_cache / estimate_num_gpu_blocks, EngineBuildRequest and the legacy Rust compile path ("this SDK entry point does not support context parallelism"). This branch supports prefill CP at exactly those entry points, so the duplicate parameters / struct field are folded into ours, the CP1 gates become positive-integer validation, and the FPM profile cell selection receives the real cp_size (a profile without that cell fails loud with "no matching FPM deployment profile"). Upstream's tests are adjusted accordingly. - FpmCompileConfig / AicTimingConfig parallel-shape checks combine upstream's `fpm_profile.is_none()` exemption with the `* cp_size` fold; aic_capacity_kwargs gains cp_size / dcp_size; fpm best_available keeps upstream's registered-architecture check ahead of the DCP mode gate. - capacity.py worker resolution carries aic_cp_size / aic_dcp_size next to aic_fpm_profile / worker_type. - ParallelismPresetConfig.prefill_context becomes Optional (None = 1), like decode_context, so default parallelism dumps carry no CP keys; the new onboarding topology tests (ai-dynamo#248) compare those dumps against the six-key request parallelism. Consumers read it through compiler._prefill_cp. Signed-off-by: Tianhao Xu <tianhaox@nvidia.com> Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
