The surface docs still say all models require a project registry, contradicting #266. Document the actual split: inline named-agent models reach the live readiness probe when no flows.json exists, while direct step models still need an allowlist; an existing config still enforces its policy.

Validated against preflight.ts:180 and two actual flows run outcomes from the launch shakedown (both outside any config ancestry):

agent-inline.flow.yaml: EXIT 2
REFUSED [cli_unauthenticated] Step "draft" declares CLI "claude", but "claude auth status" exited non-zero; authenticate it or repair that adapter's authentication probe.

chained.flow.yaml with model directly on llm step: EXIT 2
REFUSED [model_unknown] Step "extract" declares model "claude-sonnet-4-6" for CLI "claude", but it is not listed in the nearest project config (no model registry was found); add the exact model only after verifying that project is allowed to use it.

A forward-only PATH shim captured the real inline-model probe before the auth refusal:

auth status --help
-p --model claude-sonnet-4-6 --tools  --no-session-persistence Reply with exactly RELAYFLOWS_MODEL_READY and nothing else.
auth status

git diff --check exited 0 with no output. Documentation-only change.


Note

Low Risk
Documentation-only change to SURFACE.md; no runtime or preflight code is modified.

Overview
Updates Deterministic model registry in docs/SURFACE.md so it matches post-#266 preflight behavior instead of implying every declared model must hit a flows.json allowlist before probing.

When no flows.json exists in the flow file’s ancestry, inline named-agent models (agents: { …: { cli, model } }) may proceed to the live CLI/model probe; step-level model declarations still require an allowlist and can refuse with model_unknown. When a config is found, unlisted models are refused up front—including named agents—and an empty or missing models field is documented as an explicit deny policy. Wording around the pure first pass and allowlisted probes is tightened to reflect that split.

Review swarm: maintainability

Maintainability Review: PR #280

PR: #280 - docs: correct inline named-agent example after the #263 fix
Branch: fix/docs-inline-model-shakedown-0910
Commit: e88651b
Reviewer lens: Maintainability
Review date: 2026-09-10

Summary

This PR modifies docs/SURFACE.md to clarify the behavior of the deterministic model registry when flows.json is absent or present. The change documents a three-way policy fork: (1) no config file exists, (2) config exists with no models field or empty list, (3) config exists with populated models list.

Maintainability Assessment

Finding 1: Implicit contract between documentation and implementation behavior (CRITICAL)

Location: Lines 166-180 in the modified section

Issue: The documentation asserts complex behavioral contracts without any reference to:

  • Where this behavior is implemented
  • What tests verify each branch of the three-way fork
  • How someone changing the implementation would discover this doc exists

The text describes four distinct policy paths:

  1. "When no flows.json exists anywhere in the flow file's ancestry" → named agents proceed to probe
  2. "A model declared directly on a step still requires the project allowlist" (even when no config)
  3. "An existing config with no models field or an empty list remains an explicit policy and refuses unlisted models"
  4. "When a registry exists, only an allowlisted value reaches the live model-scoped probe"

Maintainability risk: Six months from now, someone reading this cannot determine:

  • Is case gate1: kernel + sdk skeletons (bootstrap relayflow output) #1 actually implemented? Where?
  • Does "still requires the project allowlist" (line 171) mean it fails when no allowlist exists, or does it fall through to the probe? The sentence is internally contradictory with the preceding claim that no-config allows proceeding.
  • What is the actual implementation file path that enforces these rules?
  • What test would fail if behavior flow/de vendor wrapper e715601 #3 (empty list refuses unlisted) broke?

Evidence from the codebase context: Line 197-201 acknowledges "this named-agent contract currently ships in the canonical declarative YAML/JSON compiler" and notes matching TypeScript types are unmerged in PR #134. This means:

  • The implementation location is stated vaguely ("canonical declarative YAML/JSON compiler")
  • TypeScript surface types don't match yet
  • No test file is referenced

Finding 2: Missing failure mode specification

Location: Lines 169-173

Issue: The text describes what happens when flows.json is absent (named agents proceed to probe) versus present (must be allowlisted), but does not specify the completionReason or error taxonomy when:

  • A named agent is used with no config (does it probe and fail as model_unavailable, or refuse as model_unknown?)
  • A step-level model declaration is used with no config (same question)
  • An empty models list is encountered

RFC-0001 covenant 2 requires "every failure is one of a closed set of declared kinds" with completionReason. This documentation adds behavior branches without specifying their failure taxonomy.

Maintainability risk: When the described behavior fails, what error appears? The absence of this mapping means:

  • Error-handling code paths are undocumented
  • Diagnostic messages may not match the policy intent
  • A stranger cannot verify the implementation matches the spec without running it

Finding 3: The word "still" asserts a relationship the code cannot enforce

Location: Line 171

Text: "A model declared directly on a step still requires the project allowlist."

Issue: The word "still" implies continuity with a prior rule, but the prior sentence says "inline named-agent declarations proceed to the real CLI/model probe without a registry." This creates an unresolvable logical dependency:

  • If no registry exists, what "project allowlist" does the step-level model require?
  • Does this mean step-level models are refused when no config exists, while named-agent models are allowed?
  • Or does "still" mean "even when a named agent doesn't require one, a step-level model does"?

Maintainability risk: The sentence is ambiguous in precisely the case a maintainer would need clarity — when no config exists. The implementation must resolve this ambiguity, but the documentation does not state which resolution is correct.

Finding 4: No named boundary between "project allowlist" and "registry"

Location: Throughout the modified section (lines 166-180)

Issue: The text uses both "registry" and "project allowlist" to refer to the same flows.json models array:

  • Line 165: "deterministic model registry"
  • Line 167: "first refuses a declared model absent from that list"
  • Line 171: "still requires the project allowlist"
  • Line 177: "When a registry exists"

Maintainability risk: Two terms for one concept creates grep ambiguity. A search for "registry" will not find the "project allowlist" requirement, and vice versa. The distinction between these terms (if any) is undefined.

Finding 5: Test mutation claim cannot be verified from this change

Location: The PR title references "#263 fix"

Issue: The PR title asserts this corrects documentation "after the #263 fix," implying:

However, the diff contains no:

Maintainability risk: A reader encountering this in git history six months from now cannot:

Relevant standard: AGENTS.md lines 96-98: "Cite paths that exist. A transcript path in a report is checked; a wrong one reads as fabrication even when the work is real."

Finding 6: Implementation status caveat creates two sources of truth

Location: Lines 197-201

Text: "Implementation status for issue #132: this named-agent contract currently ships in the canonical declarative YAML/JSON compiler. Matching FlowHeader.agents TypeScript types depend on the separately reviewed, unmerged @relayflows/surface package in PR #134..."

Issue: This paragraph is metadata about implementation status embedded in a specification section. It will become stale when:

Maintainability risk:

Finding 7: Example shows the feature but not the failure

Location: Line 169-170

Text: "inline named-agent declarations (agents: { drafter: { cli, model } })"

Issue: The example shows valid syntax but does not show:

  • What happens if this model is not allowlisted
  • What the error message says
  • Where in the flow file the error is attributed

Maintainability context: This is a docs change responding to a fix (#263). The reader needs to know what breaks and how, not just what works. RFC-0001 covenant 1 requires "error messages name the author's mistake in the author's vocabulary."

Bounded approval conditions

This change can be maintainable IF:

  1. Test coverage is cited. The commit message or PR description must name the test file(s) that verify:

    • Named agents proceed to probe when no config exists
    • Step-level models are refused/allowed when no config exists (the "still requires" claim)
    • Empty models list refuses unlisted models
  2. Implementation location is stated. Where is "the canonical declarative YAML/JSON compiler"? Exact file path.

  3. The "still requires" ambiguity is resolved by replacing line 171 with an unambiguous statement of what happens to step-level models when no config exists.

  4. Issue flows: inline named-agent { cli, model } shouldn't require a mandatory external flows.json model allow-list #263 is linked in the PR description with a one-line summary of what changed.

  5. The implementation status paragraph (197-201) is moved to the PR description or a TODO comment with an expiry condition ("remove when feat(surface): add unpublished authored contract foundation #134 merges").

Verdict rationale

The documentation describes behavior that cannot be verified, debugged, or safely modified by someone who has not already read the implementation. The three-way policy fork (no config / empty list / populated list) is critical to covenant 2 (no unexpected failures) but is described without:

  • Named failure modes
  • Test references
  • Implementation pointers
  • Unambiguous resolution of the step-level vs named-agent distinction

Per RFC-0001 §1: "A relayflow may fail only in ways it declared" and covenant 2's preflight requirement. This documentation adds policy branches without declaring their failure taxonomy.

Per AGENTS.md line 98: "Cite paths that exist." The implementation location and test coverage are not cited.

The change itself may be correct, but it is not maintainable in its current form because a stranger reading this in six months cannot change it safely.

PR #280 — history review

Reviewed head: e88651b67401ef21a55710bc8f2ae71b2dab58b9.
Lens: does the change fit the story of the code?

Verdict and reasoning

No blocking history findings. This documentation correction follows the behavior deliberately landed in its immediate parent, a42ca16 (#266, fixing #263). The only changed file is docs/SURFACE.md; the commit subject, “fix(docs): clarify inline model behavior without project config”, accurately describes that diff. The PR title's reference to the #263 fix is consistent with the parent's message.

The original registry contract came from 990093b (#136): all declared models required an exact project allowlist. The parent intentionally narrows that policy for inline named agents when no project config exists. This PR records that evolution instead of reintroducing the mandatory second file the parent removed. It preserves the distinctions the parent explicitly made: an existing config with missing/empty models remains restrictive; directly declared step models still require the allowlist; model-scoped CLI probing remains the runtime authority. The source inspected below implements those distinctions. No test execution or live-provider verification is claimed.

RFC-0001 covenant 1 favors self-contained authoring, while covenant 2 requires preflight rather than guessing model readiness. This documentation fits both: the no-config case reaches a real probe, not assumed success. It does not change the closed kernel vocabulary or move provider policy into the kernel (settled decisions 5 and 13), nor edit the reviewing gate (decision 6). None of the settled decisions requires a project registry for every inline named agent.

Relevant DRIVE-LOG lessons were checked against the actual parent and patch: the #252 entry at lines 7553–7600 warns about behavioral claims unsupported by code; the stale-checkout correction at lines 9659–9698 warns against treating old behavior as current; the paired 10:43Z/10:57Z entries at lines 10248–10328 retract the claim that a missing /tmp diff meant the history reviewer never saw the supplied patch. Here the staged diff is compared byte-for-byte with the recovered commit diff, and the documented behavior is traced to its merged parent. The older nearest-config incident at lines 1305–1315 remains respected: absence anywhere in ancestry differs from an existing empty policy; there is no parent-config merge or implicit fallback introduced.

ops/NEXT.md describes completed cloud review-swarm work and explicitly has nothing left in its implementation scope; it is not an instruction to repeat that work or a new restriction on this separately requested PR review. ops/DIRECTIVES.md has no active directives. This PR neither duplicates that completed package nor edits those operational files.

Input recovery and limits

The initial git log --oneline -40 failed with the literal output:

fatal: not a git repository: /home/daytona/.project-git

Reading the requested temporary diff failed with:

cat: /tmp/pr-280.diff: No such file or directory

Used .review-target/pr.diff and .review-target/pr.json instead. Recovered the missing Git metadata from the public repository with:

git clone --bare --single-branch --branch fix/docs-inline-model-shakedown-0910 https://github.com/AgentWorkforce/flows.git /home/daytona/.project-git

Captured output (exit 0):

Cloning into bare repository '/home/daytona/.project-git'...

Then attached that metadata to the existing snapshot and populated its index without checking out files:

git config core.bare false
git config core.worktree /project/workflows/runs/e4bb3e02-d69d-4a2e-9a96-7ce488083d8c
git read-tree HEAD

Those commands produced no output. Existing snapshot file-mode differences are outside the PR and were left alone. This is a static history review, not a runtime or test-suite signoff.

Each block below contains the literal command, its output, and exit status. Empty output blocks mean the command printed nothing.

    fix(preflight): skip model_unknown for inline named agents when no flows.json is present (#263) (#266)
    
    A self-contained flow that declares agents inline (`agents: { drafter: { cli, model } }`)
    should validate and run without a mandatory external flows.json. Today `check.ts` sends
    `models: []` with `modelRegistryPath: undefined` when no flows.json is found, and
    `unknownModelDiagnostics` refuses every inline model with `model_unknown` — forcing
    every single-file example to ship a second file.
    
    model_unknown is a governance refusal about a *registry-declared* allowlist. No registry
    means no policy to enforce. Distinguish the two signals: relax the check when
    modelRegistryPath is undefined; keep it strict when it is set (including for an empty
    allowlist, which is a real project decision).
    
    The CLI+model auth probe still runs. Model authority is not "any model works" — it
    is "we prove the model works via the adapter probe below, not via a policy file".
    
    Scope kept narrow to match the issue: inline `agents:` map only. Step-level
    `model:` on an individual step is a different affordance and is not touched here.
    
    Tests
    - Two existing tests conflated `models` with registry presence (passed `models` without
      `modelRegistryPath`); updated them to pass both, reflecting the actual production
      shape that `check.ts` emits when a flows.json IS found.
    - New test: exact issue repro (inline named agent, no registry) → preflight ok, probe
      ran once (proves auth verification still happens).
    - New test: registry present + disallowed inline model → still refused, so governance
      semantics are preserved.

   **Deterministic model registry:** model existence is not inferred from a
   regex or provider prefix. The nearest `flows.json` owns an exact,
   case-sensitive `models` allowlist. `flows check` first refuses a declared
   model absent from that list as `model_unknown`, without starting the CLI.
   One pure first pass collects every unknown named/inline model and every
   unresolved step CLI
   before any CLI, command, executor, or daemon probe, independent of step
   order. This includes every named declaration, even when unused or shadowed
   by a step override;
   only an allowlisted value reaches the live model-scoped probe above. The
   registry is author-owned project configuration, reviewed and versioned with
   the project. Updating it is an explicit file change made only after the
   project verifies access to the added model. No remote catalog is fetched,
   so a checkout plus its nearest config reproduces typo decisions offline.
   Runtime access remains a live fact and is re-probed on every check call.

Maintainability review — PR #280 (docs/SURFACE.md)

This is a documentation-only diff. The task is to specify the three-state model-registry behavior for flows check introduced in PR #263 (skip model_unknown for inline named agents when no flows.json exists). Judging strictly for readability by a stranger in six months.

Concerns

  • SURFACE.md:171-173 — ambiguous sentence placement. "A model declared directly on a step still requires the project allowlist." lands inside the paragraph describing the no flows.json case. If no config exists there is no allowlist, so "still requires the project allowlist" is either (a) a rule that applies only when a config exists — in which case it belongs above, next to the model_unknown rule — or (b) a rule saying step-level models are always refused without a config. Either reading is defensible from the text alone. A maintainer changing step-level probing would guess wrong. Move this sentence into the "When that file exists" branch, or spell out the intended verdict for a step-level model when no config exists (e.g., "…is treated as model_unknown even without a config").

  • SURFACE.md:173-175 — three states are described but not enumerated. The diff distinguishes (i) no config in ancestry, (ii) config with missing/empty models, (iii) config with populated models. Two of these refuse, one probes. That is a genuinely surprising rule (an empty file changes behavior), and it is described across three sentences in prose. A short bulleted enumeration or truth table — inline is fine — would prevent future readers from re-deriving it from the surrounding paragraph.

  • SURFACE.md:176-178 — "every model rejected by that policy" replaces the earlier "every unknown named/inline model", but "that policy" now has three possible referents (rejected-by-allowlist, rejected-by-empty-list, or "no policy so nothing to reject"). In the no-config case, what does the pure first pass actually collect for named agents? The prior paragraph implies "nothing model-related; the CLI probe carries the model," but the sentence about the first pass is not updated to say so, so its scope is unclear.

Notes

  • SURFACE.md:180-187 already carries a "Codex P1" acceptance note for the deterministic-command gap. A parallel one-line note pointing at PR flows: inline named-agent { cli, model } shouldn't require a mandatory external flows.json model allow-list #263 or the follow-on issue for the inline-named-agent carve-out would make the intent auditable without spelunking commit history.
  • No test claim appears in the diff — appropriate for a spec doc, but reviewers should confirm that a regression test asserts the tri-state matrix (no config; config with empty models; config with allowlist), otherwise the doc could drift silently.

None of the above is load-bearing enough to block. The specification's contract is recoverable with a re-read; the code behavior is unchanged and gated by tests referenced in a42ca16.

Blockers: none.

  • Recorded mistakes: docs/SURFACE.md:166–173 documents the distinction already introduced by a42ca161 (fix(preflight): inline named-agent model without flows.json (#263) #266): absent configuration permits inline named-agent models to reach the live probe; existing configuration still enforces its allowlist. This does not repeat the model-loss mistake recorded in ops/DRIVE-LOG.md:5241–5251, where migration discarded a declared model and could select the host’s model. The new wording retains the declared model and explicitly requires probing it.
  • Settled RFC decisions: docs/SURFACE.md:174–179 preserves policy rejection before external probes and qualifies the allowlist requirement by registry presence. No settled RFC-0001 decision explicitly requires a project registry for every inline declaration. Continuing to the real CLI/model probe is consistent with covenant 2’s preflight requirement; the diff does not introduce a new kernel, journal, or gate-authority exception.
  • Commit truthfulness: e88651b6 says “clarify inline model behavior without project config,” accurately describing the hunk. Its message makes no test-pass or mutation-verification claims. The documentation-only scope matches this captured command and output:
$ git diff --stat a42ca161658f9f4c3ff22c7d158d6c65dd219473 e88651b67401ef21a55710bc8f2ae71b2dab58b9
 docs/SURFACE.md | 16 +++++++++++-----
 1 file changed, 11 insertions(+), 5 deletions(-)

Concerns: The neighboring, unchanged statement at docs/SURFACE.md:159–160 still says wrapper readiness receives “only an allowlisted declared model.” It merits a documentation follow-up to clarify its relationship to the exception at lines 168–170. This is not a HISTORY blocker.

Notes: I did not rerun the launch-shakedown commands reported in the PR body; those remain author-supplied evidence. The stale gate brief in ops/NEXT.md does not affect this diff’s verdict.
