Why and what changed

aisimulate recommend needs an extensible output boundary so integrations can consume search events and produce their own artifacts without putting integration-specific code into AISimulate.

This PR adds output adapters, selected with repeatable --output NAME options and discovered through the aisimulate.output_adapters entry-point group. Each selected adapter receives its same-named top-level configuration section and can participate in two phases:

  • subscribe(config) is optional and returns on_candidate and/or on_round callbacks. The supervised worker connects them directly to Sweeper.run so the adapter can consume live search results.
  • write(config, result=..., output_dir=...) is required and writes final artifacts after recommend has written its canonical output.

--stack continues to select the simulation implementation; --output independently selects output integrations. AISimulate owns the generic adapter lifecycle, while packages such as Dynamo own their concrete artifact generation. Existing write-only adapters remain compatible.

This continues #113, which was accidentally closed during a rebase and cannot be reopened.

Review map

  • Risk level: medium
  • Start with: python/aisimulate/src/aisimulate/output_adapter.py, then the worker wiring in python/aisimulate/src/aisimulate/recommend.py
  • Public or serialized contract changed: yes; a new output-adapter entry-point group and lifecycle are introduced
  • Compatibility or rollback concern: subscribe(config) is optional. Live callbacks execute synchronously and abort recommend if they fail. The worker subscriber and final writer may be separate adapter instances, so adapters must not rely on shared in-memory state between phases.

The three Sweeper callback commits from #319 are temporarily stacked here so the output-adapter lifecycle can be tested end to end. Once #319 merges, rebasing this PR drops those duplicate commits.

Evidence

  • Tests: PYTHONPATH=python/aisimulate/src python/aisimulate/.venv/bin/pytest -q tests/test_output_adapter_discovery.py — 10 passed
  • Tests: GIT_CONFIG_GLOBAL=/dev/null python -m pytest -c /dev/null .github/codeowners/test_*.py -q -p no:cacheprovider with the project venv on PATH — 107 passed
  • Static checks: Ruff check passed for all changed Python files; Ruff format check passed; compileall and git diff --check passed
  • CODEOWNERS: strict coverage 3519/3519 (100%), generated artifacts match
  • Fast CI: passed for current head 26c99f4b
  • Full CI: pending for current head
  • CodeRabbit reviewed commit: pending for current head
  • Codex reviewed commit: 26c99f4b
  • Negative or boundary cases: unavailable and invalid adapters; unsafe or missing reported paths; callback mutation isolation; callback error attribution; absent subscriptions; output configuration crossing the supervised-worker boundary
  • Expected-value derivation: N/A
  • Before/after output, trace, benchmark, or golden diff: N/A

The native-extension-dependent CLI suite was not run locally because this macOS host cannot link the Rust extension until its Xcode license is accepted; CI provides that coverage.

Modeling or data provenance

N/A. This changes plugin and CLI control flow, not simulation models, formulas, or datasets.

📝 Summary

Risk: Moderate. Human attention should focus on:

  1. How recommend handles repeated --output names and removes selected configuration sections before core validation.
  2. Adapter discovery and API validation, including callback timing and artifact-path checks.
  3. Failure ordering: canonical outputs are written before adapters run, but an adapter failure still fails the command.

recommend accepts repeatable --output NAME options. Each selected name requires a same-named top-level mapping. AISimulate resolves selected adapters from aisimulate.output_adapters and passes each adapter its configuration, the SweepResult, and the prepared output directory. A writer reports relative paths to artifacts that exist after the call. Adapters may subscribe to synchronous on_candidate and on_round callbacks. Callback failures abort recommendation. The supervised callback worker and final writer may use separate adapter instances. --stack remains independent of --output, and write-only adapters remain supported.

The public contract adds RecommendationOutputAdapter, RecommendationOutputCallbacks, API version 1, adapter discovery and execution functions, and resolution and execution exceptions. Sweeper.run adds on_candidate. The change also modifies resource-scheduler draining behavior.

Evidence supplied: The change summary describes adapter discovery, validation, artifact writing, callback tests, and CLI tests for both engine and dynamo stacks. The objectives report 10 adapter-discovery tests and 107 CODEOWNERS tests passing, along with Ruff, compileall, diff-check, and CODEOWNERS coverage results. These results are author-reported and not independently verified. The objectives report fast CI passed for the named head; full CI and CodeRabbit review were pending. The native-extension-dependent CLI suite was not run locally. Current review findings and severity counts were not supplied. The requested shell inspection returned no status or diff output, so it provides no further evidence about current checks or review status.

Technical quality: The supplied tests and documentation cover key adapter and callback contracts. Reported local checks provide supporting evidence, but do not establish independently verified results or current review findings.

Merge readiness: Full CI and review status are not established by the supplied evidence. A bot review is not approval.

Walkthrough

The recommend command accepts repeatable output-adapter selections. It separates selected adapter configuration from recommendation input, resolves and runs adapters, and supports candidate and round callbacks during search. The resource scheduler also drains completed futures across generator yield pauses.

The scheduler repeatedly polls and drains completed futures after yielding results. Regression tests cover completions during generator pauses, including after the replay deadline.

Priority: ⬇️ Low

Estimated code review effort: 4 (Complex) | ~35 minutes

Merge Risk: 🔵 Low · up to 26c99

Passing an --output name that collides with a core section together with --overwrite may delete earlier outputs before the command fails. This is a narrow misuse case, so the risk is low, but the supervisor should apply the same name checks before cleanup.

Full details: Cross-Layer Contract

Explanation

The output-adapter contract is not traced through the empty-result CLI path. main._recommend writes recommendation.json and recommendation.csv, then returns at the not selected branch before calling write_output_adapters. The documented contract says the selected adapter receives the final SweepResult and output directory after recommendation, and the existing empty-result test does not cover a selected adapter. Therefore a selected adapter produces no artifact when all candidates are infeasible or resource-limited.

Resolution

Invoke write_output_adapters(output_adapters, output_configs, result=result, output_dir=root) on every completed recommendation, including when selected is empty. Keep canonical result files written before the adapter call. Preserve the existing nonzero status for an empty result and wrap adapter failures as command failures. Add a CLI regression test with --output and an empty SweepResult that verifies the writer receives the final result, writes an artifact, and still returns the expected failure status.

Linked repositories findings

ai-dynamo/dynamo

  • Dynamo pins aisimulate==0.12.0 in both project dependencies and its container wheelhouse. Any adapter API added after that release requires a coordinated version/pin update. [::ai-dynamo/dynamo::]
  • Dynamo currently registers only sweep_config_providers, runner_factories, and config_adapters; there is no aisimulate.output_adapters registration. Its dependency test asserts these entry-point mappings exactly, so the future DGD adapter integration must update pyproject.toml and tests/dependencies/test_aisimulate_consistency.py. [::ai-dynamo/dynamo::]
  • Existing Unified CLI integration uses --stack dynamo for the replay runner and the dynamo.router/dynamo.planner configuration adapters. Output selection is therefore a separate, currently unimplemented integration boundary. [::ai-dynamo/dynamo::]

ai-dynamo/aiconfigurator

  • The frozen compatibility implementation exposes recommendation artifacts through save_dir and save_results, not output-adapter discovery. cli_recommend returns a CLIResult while optionally writing artifacts. [::ai-dynamo/aiconfigurator::]
  • Its documented Dynamo output is a nested per-candidate layout containing k8s_deploy.yaml, engine configs, benchmark files, and run scripts. A future output adapter reproducing this behavior must define how the single prepared adapter directory maps to these candidate subdirectories. [::ai-dynamo/aiconfigurator::]

Reject output names that collide with recommendation-owned sections.

_extract_output_configs pops name from raw before split_config_sections. If --output names a core section such as traffic, evaluation, execution, or optimizer, that section is removed from the recommendation input. The recommendation then runs with defaults. The command can complete with different inputs or scores. Nothing warns the user.

Reject every name in RECOMMENDATION_CORE_SECTIONS, and also optimization and optimizer, before remaining.pop. Add a negative CLI test for this case.

Linked repositories findings

ai-dynamo/dynamo

  • Dynamo pins AISimulate to the exact dev release 0.13.0.dev202609270000000058 in pyproject.toml:17, container/deps/requirements.aisimulate.txt:5, and benchmarks/pyproject.toml:42; downstream adapter availability is therefore release/pin-coupled. [::ai-dynamo/dynamo::]
  • Dynamo currently registers only sweep_config_providers, runner_factories, and config_adapters in pyproject.toml:120-129; no aisimulate.output_adapters provider is registered. Its exact-entry-point consistency test at tests/dependencies/test_aisimulate_consistency.py:185-200 will require updating when the DGD adapter is integrated. [::ai-dynamo/dynamo::]

ai-dynamo/aiconfigurator

  • The compatibility CLI uses --save-dir and --deployment-target, with Dynamo output organized into per-mode/per-candidate directories containing files such as k8s_deploy.yaml, engine configs, benchmark manifests, and run scripts (README.md:394-454). A future output adapter reproducing this behavior must preserve or explicitly redefine this nested layout. [::ai-dynamo/aiconfigurator::]
  • AIConfigurator is in maintenance-only transition to AISimulate rather than being an output-adapter consumer (README.md:7-16). [::ai-dynamo/aiconfigurator::]

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.

Signed-off-by: Dr. Stefan Schimanski <stefan.schimanski@gmail.com>
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.

Signed-off-by: Dr. Stefan Schimanski <stefan.schimanski@gmail.com>
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.

A future Dynamo DGD adapter will require a separate packaging change. [::ai-dynamo/dynamo::]
  • tests/dependencies/test_aisimulate_consistency.py:191-201 asserts the exact current entry-point sets, so that future registration also requires updating the consistency test. [::ai-dynamo/dynamo::]

ai-dynamo/aiconfigurator

  • AIConfigurator documents that its replacement is AISimulate and directs new integrations there (README.md:8-16, docs/aisimulate_migration.md:48-67); it is not a consumer of this new adapter API. [::ai-dynamo/aiconfigurator::]
  • Its documented Dynamo output is hierarchical, with separate agg/disagg trees containing deployment manifests, engine configs, benchmark helpers, and run scripts (README.md:398-454). A future DGD adapter should preserve or explicitly redefine this artifact layout. [::ai-dynamo/aiconfigurator::]

Linked repositories findings

ai-dynamo/dynamo

  • Inspected PR branch refs/pull/13765/head at f6efef4. Dynamo pins aisimulate==0.12.0 and currently registers only sweep providers, runner factories, and config adapters—no aisimulate.output_adapters entry point (pyproject.toml:17,120-129). [::ai-dynamo/dynamo::]
  • tests/dependencies/test_aisimulate_consistency.py:179-195 asserts these exact entry-point sets, so a future Dynamo output adapter must update that compatibility test as well. [::ai-dynamo/dynamo::]
  • Existing DGD materialization code is present, but no current consumer of the new output-adapter API was found. [::ai-dynamo/dynamo::]

ai-dynamo/aiconfigurator

  • Inspected checkout f254959. AIConfigurator is maintenance-only and directs new integrations to AISimulate (README.md:8-16,38-81); it is not a consumer of this API. [::ai-dynamo/aiconfigurator::]
  • Its documented generated-output contract uses separate agg and disagg trees with deployment manifests, engine/config files, and run scripts (README.md:398-454). A future adapter replacing this integration should preserve or explicitly redefine that layout. [::ai-dynamo/aiconfigurator::]

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.

* feat(cli): prototype recommendation output adapters

* 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. Purely additive: defaults to None, zero behavior change for
every existing caller.

* fix(sweeper): detach on_candidate records and close wave-timeout race

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.

* fix(sweeper): repeat non-blocking drain until empty, not once

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.
