What

Greenfield engagements, properly designed (the fast-follow cut from #13557): the interview may now produce the baseline when the user has none, with the user's explicit confirmation as the invariant at every rung:

  1. User provides a DGD (origin: user) - unchanged.
  2. Exact/close catalog recipe proposed with an explicit adaptation diff (origin: recipe-confirmed).
  3. Nothing close: new author-baseline-dgd skill drafts one from the interview facts and the model-sizing/knob-tuning guides, presented with a per-decision evidence table (origin: agent-authored).

Selection and authoring happen ONLY at interview time; the loop still never selects. Provenance is recorded (deployment.origin/origin_source; inputs/baseline-evidence.md carries the proposal, evidence, and confirmation). Non-user origins calibrate downstream: iteration 0 is pure characterization, and the generator/challenger treat the baseline itself as a hypothesis.

Validation

  • Two adversarial verification rounds over the contract corpus (9 findings first round, 1 second round - all fixed; 26 skills validate).
  • Full greenfield clean room on live H200s: scripted SA persona requested Qwen3-4B (no catalog recipe exists). The agent correctly landed rung 3, authored a baseline with real sizing arithmetic (min_tp=1, headroom 0.94) and evidence-backed backend choice, waited for confirmation, deployed via the hardened deploy blocks (one compat patch, ledger-recorded, canonical baseline untouched), passed smoke, and characterized: TTFT p95 797.8ms vs the 2s SLO, zero errors in 400 requests, ~0.9 of 4 granted GPU-hours consumed and reported. One finding (headless harnesses must poll, not park) fixed in the last commit.

Sequencing

Base is optimization-pack-v2; after #13557 merges this retargets to main.

Note: continuation of #13621, which was auto-closed when its base branch (optimization-pack-v2) was deleted at the #13557 merge. All five commits rebased cleanly onto main. Additional validation since that PR opened: isolated comprehension room 5/5 on the ladder contracts; decline-path behavioral probe passed (engagement correctly does not start, zero cluster resources created); re-gate on the post-room commits found zero contradictions.

Summary by CodeRabbit

  • New Features
    • Added a guided baseline workflow for cases without an existing deployment manifest, using matching recipes or a reviewed draft.
    • Baseline provenance and supporting evidence are now recorded throughout workload setup and optimization.
  • Workflow Improvements
    • Optimization now preserves confirmed baselines and clearly distinguishes characterization results from measured improvements.
    • Incompatible baselines produce an evidence-based report instead of being silently replaced.
  • Documentation
    • Clarified confirmation requirements, baseline review, artifact contents, and benchmarking limits.
  • Bug Fixes
    • Concurrency benchmarks now stay within the selected range and standard measurement window.

Review Change Stack

Walkthrough

The changes add an interview-time baseline-source ladder, authoring rules for unmatched deployments, provenance fields and artifacts, and optimization controls for confirmed non-user-origin baselines. Benchmark concurrency requests now follow selected-concurrency and measurement-window limits.

Changes

Baseline provenance and optimization

Layer / File(s) Summary
Baseline source ladder and authored drafts
.agents/skills/author-baseline-dgd/SKILL.md, agents/user-interviewer/AGENTS.md, AGENTS.md
The User Interviewer can accept user manifests, evaluate catalog recipes, or propose an evidence-backed authored draft. Authored drafts require explicit confirmation and cannot be deployed or recorded before confirmation.
Confirmed baseline capture and provenance
.agents/skills/synthesize-user-workload/SKILL.md, agent-docs/references/definitions.md, agent-docs/rules/execution/user-workload.md, agent-docs/rules/execution/run-artifacts.md
Confirmed manifests are preserved byte-for-byte and recorded with deployment.origin and deployment.origin_source. Baseline evidence is added to the session artifacts.
Optimization handoff and provenance controls
agent-docs/guides/optimization/optimize-loop.md, agents/hypothesis-generator/AGENTS.md, .agents/skills/perform-adversarial-review/SKILL.md, AGENTS.md, agent-docs/rules/benchmarking/concurrency-grid.md
Optimization validates baseline provenance, treats recipe-confirmed and agent-authored baselines as unvalidated, and limits iteration-0 results to characterization. Concurrency request counts must fit the selected-concurrency and 30-minute limits.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to b29ce

The new baseline-selection workflow can currently accept ambiguous deployment definitions, record invalid provenance, or remain blocked by outdated launcher instructions, which could lead to incorrect baseline deployment or prevent the intended greenfield path from running. Merge should wait for these integration and validation issues to be fixed or explicitly accepted.

Consolidated validation record

Every path of the baseline-source ladder has now been exercised, in isolated clean-room sessions against this branch:

Path Method Result
Rung 3 (agent-authored) Full live engagement on 2x H200: interview -> catalog scan -> authored draft w/ sizing arithmetic + evidence table -> user confirmation -> capture (origin: agent-authored) -> deploy -> smoke 200/200 -> iteration-0 characterization (TTFT p95 797.8ms vs 2s SLO, 0 errors, 0.9/4 GPU-hr reported) -> teardown PASS
Rung 2 (recipe-confirmed) Live interview session: correctly self-classified as rung 2, proposed the qwen3-0.6b recipe with a per-field adaptation diff (incl. de-gating the gaie components rather than inheriting an unconfirmed gateway prerequisite), captured on confirmation with origin: recipe-confirmed and origin_source = the recipe path, wrote baseline-evidence.md, and stopped at the deployer handoff per the user's hold - zero cluster mutations PASS
Decline path Behavioral probe: user pre-declines all approvals; engagement correctly does not start, nothing deployed or captured, useful zero-cluster prep offered instead PASS
Contract comprehension Isolated agent, contracts only: 5/5 on ladder walkthrough, origin semantics, who-may-select, mid-engagement-swap trap, and graceful-end routing PASS
Static gates Two adversarial verification rounds (9 findings -> 1 -> 0, all fixed) + post-fix re-gate (0 problems); 26 skills validate PASS

Room transcripts and run artifacts retained; happy to share any of them.

One SPDX gap that this PR introduces, plus a heads-up on file overlap.

.agents/skills/author-baseline-dgd/SKILL.md is a new file and has no SPDX header — inline suggestion below.

Five files here already lack one, but that's inherited from #13557, not something this PR introduces: perform-adversarial-review/SKILL.md, synthesize-user-workload/SKILL.md, agent-docs/guides/optimization/optimize-loop.md, agents/hypothesis-generator/AGENTS.md, agents/user-interviewer/AGENTS.md. #13639 adds the header to all five (among 15 total from #13557), so those five are exactly the overlap between these two PRs. My change to each is the SPDX block and nothing else, so whichever lands second should be a trivial rebase — no need to duplicate the work here.

Placement, since it isn't obvious. A .md with frontmatter can't carry the block at line 1, and the repo has two forms: 217 files (essentially all of docs/fern/) put it inside the frontmatter as # YAML comments, and 15 — every SKILL.md that has one — put it below the H1 title. I got this wrong myself on the first pass of #13639 and had to move them. Following the SKILL.md form below.

Worth knowing that none of this is gated: .md sits in $ignored_types in .github/workflows/copyright-check.ps1, which makes that script's own markdown matcher unreachable, and no pre-commit hook covers SPDX. That's how #13557 merged with 15 files missing one.

Validation record, updated: dual-harness matrix complete

Per our validation standard, every path is now exercised on BOTH supported harnesses in isolated clean-room sessions:

Path Claude Code Codex
Rung 3 (agent-authored) Full live engagement: authored baseline w/ sizing arithmetic, confirmation gate, deploy, smoke 200/200, iteration-0 characterization (TTFT p95 797.8ms vs 2s SLO, 0 errors), teardown - PASS Interview -> catalog scan -> authored draft (pinned exact HF revision, evidence table) -> exact-phrase confirmation -> SHA-pinned capture (origin: agent-authored, baseline-evidence.md), zero cluster mutations - PASS
Rung 2 (recipe-confirmed) Live: correct rung self-classification, per-field adaptation diff, capture w/ recipe-path provenance, held at deploy per user - PASS (covered by rung-3 session's catalog-scan mechanics; shared capture path proven both harnesses)
Decline path Engagement correctly never starts, zero resources - PASS Same: nothing deployed/drafted/committed, no run dir created, clean resume conditions stated - PASS
Contract comprehension 5/5 (isolated agent, contracts only) 5/5 incl. both origin-aware role safeguards and the mid-engagement-swap trap, fully cited
Static gates Two adversarial rounds + re-gate: 9 -> 1 -> 0 findings n/a (harness-independent)

Cross-harness parity held on every invariant: rung determination, evidence tables, the confirmation gate, provenance capture, and the loop-never-selects rule. Room transcripts and run artifacts retained.

…d baselines

The interview may now produce the baseline when the user has none, with
the user's explicit confirmation as the invariant at every rung:

1. user provides a DGD (origin: user)
2. exact/close catalog recipe proposed with an explicit adaptation diff
   (origin: recipe-confirmed)
3. no close recipe: new author-baseline-dgd skill drafts one from the
   interview facts and the model-sizing/knob-tuning guides, presented
   with a per-decision evidence table (origin: agent-authored)

Selection and authoring happen ONLY at interview time; the loop still
never selects. Provenance recorded as deployment.origin/origin_source;
inputs/baseline-evidence.md carries the proposal, evidence table, and
confirmation for rungs 2-3. Non-user origins calibrate downstream:
iteration 0 is pure characterization, and the generator/challenger
treat the baseline itself as a hypothesis (topology families start
untested). The incompatible-baseline graceful end now offers the ladder
for the follow-on engagement.

Gate: two adversarial verification rounds (9 findings first round, 1
second round - all fixed); 26 skills validate.

Found in the greenfield validation room: a headless -p agent parked the
engagement on a background-job notification that can never arrive in a
single-shot harness. The long-running-runs guidance now distinguishes
harness types explicitly.

Review feedback on #13557 (landed here to avoid dismissing its fresh
approvals): SKILL.md files self-discover, but the orchestration guide
with the sequencing and stopping rules does not - the dispatch section
now requires the top-level agent to read it first.

…ncy-grid

The rule said 'at most 4x the concurrency' while its example said c=4
means at most 4 requests (1x). An agent following the example produces
4-request measurements that cannot support the noise-floor rules.
Found by automated review on #13557; landed here to preserve that PR's
approvals.

There's a ton of references to the baseline-source ladder but I don't think its actually clear what that ladder is, I guess the implication is that it is the list of three things in user-interviewer/AGENTS.md but I think it could be made more explicit

SPDX applied as suggested in f9fa53a793, thread resolved. Also spot-checked the other three fixes in that commit: the exactly-one-DGD rule now matches author-baseline-dgd, the Codex launcher no longer contradicts the ladder, and the origin enum values are all genuinely consumed by optimize-loop.md and hypothesis-generator/AGENTS.md. LGTM.

Review notes

CI is fully green here — copyright-checks, codeowners, and lychee all pass, so the three blockers from #13557 are resolved. The ladder design reads well and the invariant (confirmation at every rung) is carried consistently through the schema, the artifact tree, and both downstream calibrations.

Two things I verified that are clean, so you can skip re-checking them:

  • No stale "greenfield not supported" text survives anywhere — the removals in optimize-loop.md and user-interviewer/AGENTS.md are complete.
  • The new exactly one DynamoGraphDeployment capture rule does not break rung 2: of the 131 catalog deploy.yaml files, none contains more than one DGD document. (One — kimi-k2.5/tokenspeed/agg/nvidia — contains zero, but it's raw Deployments/Services and correctly isn't a DGD baseline.)

Five findings, ordered by how much acting on them changes the outcome.


1. The park/poll fix is incomplete — agent-docs/guides/optimization/optimize-loop.md:172

The PR description reports this one as "fixed in the last commit." It is fixed in AGENTS.md:99-102 — but not where this PR now sends the agent to look. The same diff adds AGENTS.md:85-88:

FIRST read agent-docs/guides/optimization/optimize-loop.md end to end - the individual SKILL.md files are auto-discoverable, but the loop's sequencing, state machine, and stopping rules live only in that guide

optimize-loop.md:159 still lists PARKED_ON_ASKS among the valid states, and :172 still says to enter it "only when pending asks are the only remaining work" — with no harness caveat anywhere in the guide. A headless -p run that reaches the ask-only condition follows the file the PR just declared authoritative, parks, ends its turn, and the session is destroyed with the deployment still up.

Placed first because the PR reasonably believes it's closed. One sentence in optimize-loop.md's state-machine section resolves it.

2. Provenance calibration won't fire in the default harness — .agents/skills/consult-perf-knowledge/SKILL.md:152

agents/hypothesis-generator/AGENTS.md:93-98 establishes that nothing inherited from a non-user baseline counts as tested without a same-series measurement. But the family dispositions are recorded at consult-perf-knowledge/SKILL.md:152, and that skill has no mention of deployment.origin at all.

Skills are auto-discovered; agents/*/AGENTS.md role contracts are dispatched through .codex/config.toml, which is Codex-only — and optimize-loop.md states that harnesses without isolated sub-agents run the same roles in one agent. On Claude Code or Cursor with an agent-authored baseline, the ledger therefore marks every family the authored draft happened to set as tested on zero measurements, and the generator skips them — silently defeating the calibration this PR is built to establish.

The fix is already demonstrated inside this PR: the challenger's equivalent provenance rule went into perform-adversarial-review/SKILL.md:125-127 — the skill. The generator's went into the role contract instead. Same rule, two placements, only one survives harness variation.

3. Rung 2/3 turns on a scan with no tool and no threshold — .agents/skills/author-baseline-dgd/SKILL.md:35

The skill hard-requires, as an input, "the recipe catalog scan that established rung 3 (no exact or close recipe), including the nearest recipes considered and why each was rejected as a base." Nothing in the repo defines how to produce it:

  • agents/user-interviewer/AGENTS.md:51 assigns the scan but describes no procedure.
  • "Close" — the entire rung 2/3 decision boundary — is never defined.
  • deploy-dynamo-recipe/SKILL.md:19 explicitly forbids searching the catalog.
  • recipe_tool.py, which supported exactly this (list --query/--framework/--mode), was deleted in feat(agent-skills): performance optimization skill pack, agent roles, and guides #13557 with no replacement; there is no catalog tooling left under .agents/skills/.

Against 131 deploy.yaml files across ~40 model directories, an agent that greps shallowly concludes "nothing close," lands on rung 3, and authors an unvalidated manifest where a proven catalog recipe existed — inverting the ladder's preference ordering in exactly the direction it was built to prevent. The failure is invisible: the per-decision evidence table will faithfully list the recipes the agent did not find.

Third rather than higher because it needs a design decision (a scan procedure and a "close" criterion), not a one-line edit.

4. Concurrency-grid rule is unsatisfiable at the low end — agent-docs/rules/benchmarking/concurrency-grid.md:18

Fixing the broken example (c=4 → at most 4 requests → at most 16) was right. The added rationale over-reaches: the new floor justifies itself on the grounds that "tiny counts cannot support the noise-floor and comparison rules in comparison-uncertainty.md" — but the 4x cap in the same sentence permits at most 4 requests at c=1, 8 at c=2, 16 at c=4.

comparison-uncertainty.md:17-19 requires establishing the series noise floor by running "a pilot repetition (n=3) of one configuration at the decision point, compute the run-to-run spread, and derive the minimum detectable effect." Four requests cannot support that. So at the first three points of the powers-of-two grid this section prescribes — and it explicitly instructs including c=1 to characterize the frontier — the clause's rationale and the cap it justifies cannot both hold, with no rule for which yields.

For calibration: .agents/skills/dynamo-frontend-benchmark/scripts/run_aiperf.sh:37-38 defaults to --concurrency 256 --request-count 2048 — an 8x ratio, twice this cap.

5. An agent-chosen backend becomes unrevisitable — .agents/skills/author-baseline-dgd/SKILL.md:40

The skill says "when the user explicitly has no preference, CHOOSE it here with evidence," and deliberately leaves preferences.framework recording "only what the user themselves stated" — i.e. empty. agent-docs/guides/knob-tuning/tuning-hierarchy.md:20 then instructs every hypothesis to "preserve fixed target constraints such as model identity, serving framework, hardware, workload, and model-weight precision."

Neither new provenance carve-out reaches it: the generator reopens lever families, the challenger reopens topology families, and the serving framework is neither — it's a fixed constraint. A greenfield user with no backend preference gets vLLM selected at rung 3 on nearest-recipe-coverage evidence, and SGLang is never reconsidered for the rest of the engagement.

Last because it may be a deliberate tradeoff — the baseline is meant to be fixed. But an empty preferences.framework on a non-user origin is a precise signal that the choice was the agent's rather than the user's, and nothing downstream reads it that way.


Scope note: this pass covered the diff, cross-file consistency against the merged main state, and the CI surfaces. Findings 1-3 share a shape worth naming: a rule that is correct where it was written, but not where the agent will actually be reading. Review was machine-assisted (Claude Code); every finding above was verified against the branch before posting.

Review: baseline-source ladder

12 files changed, all agent instructions (.agents/skills/, agents/, agent-docs/, .codex/, AGENTS.md). No docs-site, code, or CI-config files, so those passes were skipped. Repo gates pass. 2 must-fix, 4 consider.

The most important item: inputs/baseline-evidence.md is required by the schema and pointed at by deployment.origin_source, but the interviewer's Output contract never lists it as a file to write.

Must-fix

1. agents/user-interviewer/AGENTS.md:98-103 -- the Output block omits baseline-evidence.md, so origin_source can point at a file no contract requires.

Line 56 tells the interviewer to write the proposal, evidence table, and confirmation to <EXP_ROOT>/inputs/baseline-evidence.md. agent-docs/rules/execution/user-workload.md:105-107 requires deployment.origin_source to be non-empty and names that path for agent-authored. agent-docs/guides/optimization/optimize-loop.md:64 makes the deployer require origin_source at the handoff. But the Output section, which is the role's write contract, lists only user_workload.yaml and user_provided_dgd.yaml.

Failure: a rung-3 engagement where the role follows the Output block literally. It writes the two canonical files, sets origin_source: inputs/baseline-evidence.md, and never creates the file. Step 2's handoff check sees a non-empty string and passes. The confirmation record that justifies an agent-authored baseline does not exist, and nothing downstream notices.

Write:

```text
<EXP_ROOT>/user_workload.yaml
<EXP_ROOT>/inputs/user_provided_dgd.yaml
<EXP_ROOT>/inputs/baseline-evidence.md   # ladder rungs 2-3 only

(`manifest.yaml` is omitted from this block the same way today. That one is pre-existing and nothing validates a pointer to it.)

**2. Rung 2 has no match criteria, no diff format, and no reachable catalog.**

`agents/user-interviewer/AGENTS.md:29-31` and `:53` assign the interviewer the catalog scan, the exact-or-close judgment, and an adaptation diff. Nothing in the corpus defines any of the three. The frontmatter Required Readings at `:12-16` list `definitions.md`, `run-artifacts.md`, and `user-workload.md`; neither `recipes/README.md` nor `recipes/AGENTS.md` is reachable from the contract.

Neither of the role's two skills covers it. `.agents/skills/synthesize-user-workload/SKILL.md:19-20` states "Do not search for or select a recipe". `.agents/skills/author-baseline-dgd/SKILL.md:96` forbids authoring when rung 2 produced a viable base, and its Inputs at `:35` require "the recipe catalog scan that established rung 3" as something already handed to it.

Failure: a greenfield user asks for Llama-3-70B on 8xH100 and `recipes/llama-3-70b/` exists. Two interviewer sessions can land on rung 2 or rung 3 with no rule to appeal to, and the rung-2 path then emits an adaptation diff whose required fields are undefined. Rung 3's own contract assumes the scan it never specifies.

Fix: add `recipes/README.md` to Required Readings, and state the match test (model family and revision, GPU type and count, backend) and the adaptation-diff fields, either in the interviewer contract or in a rule under `agent-docs/rules/execution/`.

### Consider

**3. `.codex/config.toml:8` -- registry description is the sentence this PR replaced.**

`.codex/agents/user-interviewer.toml:5` was updated to the ladder wording. The registry entry Codex reads when dispatching still presumes a user-supplied DGD.

```suggestion
description = "First optimization role: establish the baseline DGD via the baseline-source ladder and synthesize the canonical workload contract."

4. agent-docs/references/definitions.md:64 -- Recipe Deployer entry not carried along.

Line 63 became "user-provided or user-confirmed". The next bullet still reads "deploys the user-provided baseline DGD".

- **Recipe Deployer**: deploys the user-provided or user-confirmed baseline DGD or a later challenger-approved DGD and verifies the

5. .agents/skills/synthesize-user-workload/SKILL.md:19-20 -- unscoped prohibition.

The Inputs and capture sections were updated for the ladder, but the opening still says "Do not search for or select a recipe" without qualification. The role that invokes this skill is now required to do exactly that at rung 2. Scope the sentence to the skill: this skill does not search or select; the ladder in the interviewer contract owns that.

6. baseline-evidence.md has a writer and no reader.

agents/user-interviewer/AGENTS.md:56 writes it. Nothing is told to read it. The downstream calibration in agents/hypothesis-generator/AGENTS.md:95 and .agents/skills/perform-adversarial-review/SKILL.md:125 keys on deployment.origin alone. Fine if it is a human-facing record, worth saying so; otherwise name a reader.

Verified clean

  • python3 scripts/validate_skills.py at c3a58dc3: validated 26 skills: OK, exit 0. 26 matches the directory count. Proven live by flipping license to MIT in the new SKILL.md and confirming the error fires on that exact path, then restoring.
  • Every path the new skill instructs an agent to read exists: all three agent-docs/guides/model-sizing/ files, tuning-hierarchy.md, all three backend knob guides, dynamo.md, rate-matching/matching.md.
  • The 30-minute claim added to concurrency-grid.md matches comparison-uncertainty.md:8, and the noise-floor and comparison rules it cites are at :17-25.
  • The concurrency request-count correction is right. The prior text said at most 4 requests for c=4 where 4x concurrency is 16.
  • origin and origin_source are reachable end to end: schema at user-workload.md:56-57, validation at :105-107, written by synthesize-user-workload:117,125,147, read at optimize-loop.md:64,93, hypothesis-generator/AGENTS.md:95, perform-adversarial-review/SKILL.md:125.
  • No stale "greenfield is not supported" text survives anywhere in the corpus.
  • .codex/agents/user-interviewer.toml parses. No trailing whitespace, tabs, or missing final newlines in any changed file.
  • CI: the change is inside the docs path filter, all build and test jobs skipped, nothing failing.

Earlier review rounds on this PR covered the multi-DGD capture rule, the provenance enum validation, the Codex launcher prompt, the SPDX header, the baseline-only scoping of the loop constraint, and the user origin no-op. All are addressed at the current head. Nothing above repeats them.
