Summary

PR-α — type-authority pass for the v3 service / operation / REST-endpoint substrate carriers.
Adds three new types in src/v3/std/services.dag:

  • InputField — empty record, reserved for PR-β per-field metadata; canonical name lives on the enclosing map key, not duplicated.
  • RestEndpointBinding { method: HttpMethod, path: PathTemplate } — minimal REST-realization carrier; path reuses the existing PathTemplate authority from std.effects rather than declaring a parallel path model.
  • Operation { name: String, inputs: Map<String, InputField>, endpoint: RestEndpointBinding } — uniquely-keyed input scope (duplicate input names unrepresentable by-construction); product of OperationEffect's prerequisite shape.

Single new module v3.std.services. No data rows. No fixture authority. No accessor. No test-only bridge.

Out of scope (PR-β..ω, R2 Grounding-owned)

  • data <provider>_operations: List<Operation> rows for anthropic / openai / github extdeps (T-Ground-Services, sibling of T-Ground-LanguageSpec — see feat(grounding): MethodTemplateContract Phase 1 — registry-backed row population (T-Ground-LanguageSpec scope E.1) #1195 for the MethodTemplateContract precedent these carriers mirror).
  • Extension of bootstrap_fixture_authority in src/v3/std/extdeps_bootstrap_fixtures.dag — unchanged here.
  • Public Dag accessor — lands with the first fixture in PR-β.
  • Lockstep tests against dsl/extdeps/{llm,github}/*.dag v2 sources — land with the matching fixture row in PR-β.
  • OperationEffect substrate retirement (T-ImpossibleBugs path (ii); PR-B / PR-C in the manager's sequencing).

Why this lands without a producerless-carrier complaint

Same shape as MethodTemplateContract typing in emit_model.dag ahead of T-Ground-LanguageSpec Phase 1 (#1195): type declarations are substrate authority; fixture rows are downstream population. The dissolution-tracked carrier discipline runs on the fixture side, not the type side. Inline file comment on services.dag names the dissolution trigger (PR-β..ω + ultimate OperationEffect retirement) explicitly.

Reviewer-driven shape decisions (resolved before this PR went ready)

  • Single-authority for path structure. Earlier draft declared a parallel PathSegment/PathTemplate model; reviewer flagged this as second-authority and unable to represent mixed parameter/literal segments ({secret_name}:addVersion). Resolved by import std.effects { PathTemplate } — reuses the upstream UrlPathToken = LiteralToken{text} | ParamToken{name} flat-token authority that mirrors dsl/std/http_path.dag.
  • Input-field-name uniqueness by construction. Earlier draft used inputs: List<InputField> with InputField { name: String }, admitting duplicate names. Resolved by inputs: Map<String, InputField> — Map's key invariant carries scope-identity authority. InputField becomes empty (per-field metadata reserved); canonical name is the map key only.

Verification

  • cargo run -p v3-compiler --features bootstrap-regen-fresh --bin regen_bootstrap — refreshes src/v3/compiler/src/bootstrap_generated{,_without_parse_surface}.rs + bootstrap_std_generated.rs.
  • cargo run -p v3-compiler --features bootstrap-regen-fresh --bin regen_bootstrap -- --verify — committed snapshots match fresh compile from .dag sources.
  • cargo test -p v3-compiler refresh_handwritten_parse_snapshot_manifest -- --ignored — refreshes parse_corpus_manifest.txt row for src/v3/std/services.dag.
  • cargo test -p v3-compiler --test integration services_carrier_shape — focused declaration-shape ratchet (new file, registered in integration.rs + sg0_census_test.rs hand-authored census). Asserts:
    • Operation, RestEndpointBinding, InputField resolve in the bootstrap.
    • InputField is the empty record.
    • RestEndpointBinding carries method + path only.
    • Operation carries name + inputs + endpoint only.
    • Operation.inputs instantiates Map<String, InputField>.
    • RestEndpointBinding.path resolves to PathTemplate declared in src/v3/std/effects.dag (single-authority discipline).
    • No populated value_body declarations leak into services.dag (PR-α boundary check).

Test plan

  • cargo test -p v3-compiler --test integration services_carrier_shape passes
  • cargo test -p v3-compiler refresh_handwritten_parse_snapshot_manifest -- --ignored passes
  • cargo run -p v3-compiler --features bootstrap-regen-fresh --bin regen_bootstrap -- --verify passes
  • cargo test --workspace --exclude v2-compiler-tests passes
  • cargo clippy --all-targets -- -D warnings clean
  • cargo fmt --all --check clean

Manager review: source shape is in the intended PR-α lane, but keep this draft for one more pass.

Required before ready:

  1. Regenerate bootstrap and parse manifest. A new src/v3/std/services.dag is part of the std bootstrap corpus, so this PR should include generated snapshot deltas and parse_corpus_manifest.txt after:
cargo run -p v3-compiler --features bootstrap-regen-fresh --bin regen_bootstrap
cargo test -p v3-compiler refresh_handwritten_parse_snapshot_manifest -- --ignored

Then run/record at least regen_bootstrap -- --verify and the manifest check.

  1. Add a focused shape test unless regen already gives an existing equivalent. Minimum: Dag::new() or generated std bootstrap resolves Operation, RestEndpointBinding, PathTemplate, PathSegment, InputField, and InputFieldRef, and Operation does not carry data rows/accessor authority in this PR. Keep it small.

  2. Update title/body. Current dashboard title/body are placeholders. The body should say this is PR-α type authority only, PR-β..ω fixture rows/accessors/lockstep are Grounding-owned, no bootstrap_fixture_authority row is added here, and no test-only bridge is introduced.

  3. Double-check imports. HttpMethod must resolve from the actual v3-visible authority. If std.types { HttpMethod } is not in the v3 std corpus, use the existing v3 carrier/import path or STOP+PING.

The type declaration direction is accepted; this is PR hygiene plus bootstrap inclusion.

BLOCKING (2)

Root Cause

  • src/v3/std/services.dag HTTP path structure was remodeled in services.dag instead of reusing or porting std.http_path's token-level authority → make PathTemplate use the existing UrlPathToken/PathTemplate shape before fixture rows depend on this carrier.
  • src/v3/std/services.dag Input identity is modeled as repeated string values in a list → use a keyed input scope or land the fail-closed uniqueness/resolution check with the carrier before authoring Operation fixtures.

⚠️ The carrier shape should be tightened before downstream fixture rows and effect consumers start relying on it.

Manager review on the scheduled BLOCKING findings: both are valid. Please keep #1246 draft and tighten the carrier before adding bootstrap/generated artifacts.

Required shape changes:

  1. Reuse the existing HTTP path-token authority. src/v3/std/effects.dag already mirrors UrlPathToken / PathTemplate { tokens: List<UrlPathToken> } from dsl/std/http_path.dag because v3 does not yet ship a standalone http_path.dag. Do not add a second PathSegment / PathTemplate { segments: ... } model in services.dag. Either import/reuse the existing v3-visible PathTemplate authority if the grammar accepts it, or move/port the shared path carrier as the smallest honest prerequisite. If import/name collision makes that impossible, STOP+PING rather than minting a parallel path shape.

  2. Do not leave input identity as an unchecked repeated string list. The PR can use InputFieldRef { name: String }, but it must also land a fail-closed uniqueness/resolution ratchet before PR-β fixtures depend on it: no duplicate Operation.inputs.name, and every path/input reference resolves to exactly one input in the enclosing operation. If that check cannot honestly run without fixture rows, encode the keying shape now or explicitly STOP+PING with the missing boundary.

Then continue with the original ready checklist: regen bootstrap, refresh parse manifest, add the small declaration-shape test, update title/body, and verify the HttpMethod import resolves.

The PR-α type-authority direction is still accepted; the issue is avoiding two fresh parallel authorities right before Grounding starts row population.

Follow-up manager pass on head e2f29e66: the two carrier-shape blockers look addressed in the source diff.

  • Path shape now reuses v3.std.effects { PathTemplate } instead of declaring a parallel PathSegment/PathTemplate model.
  • Input identity now uses Map<String, InputField>, so duplicate input names are structurally ruled out by the map key surface. The fixture-load ParamToken-name resolution check can land with PR-β rows.

Remaining before this is ready to merge:

  1. Update title/body. They still show dashboard placeholders. Body should state PR-α type authority only, PR-β..ω fixture rows/accessors/lockstep are Grounding-owned, no bootstrap_fixture_authority row, and no test-only bridge.
  2. Include/confirm bootstrap + parse manifest artifacts for src/v3/std/services.dag if regen produces deltas, and record the exact verify commands.
  3. Add the focused declaration-shape test from the prior manager comment, updated for the actual shape: resolve Operation, RestEndpointBinding, InputField, and confirm Operation.inputs is Map<String, InputField> and RestEndpointBinding.path points at the existing PathTemplate authority.
  4. Let CI finish. If the PathTemplate import or unqualified Map use fails to resolve, fix it or STOP+PING with the exact compiler error.

Good direction; this is now down to ratchets and publication hygiene.

  • Thinking: 260s wall

Findings

  • src/v3/std/services.dag:1 (new file in diff) — Adding another *.dag under src/v3/std automatically pulls it into the SG-2 parse corpus via collect_rel_paths in integration.rs (see parse_corpus_manifest.txt header and handwritten_parse_snapshot_matches_manifest). The PR diff does not update src/v3/compiler/tests/integration/parse_corpus_manifest.txt, so that test will diverge as soon as this file exists on disk. BLOCKING for merge/CI. Aligns with TESTING.md enforcement stance (new PRs should not leave the documented harness incoherent) and the repo’s stated hermetic / structural snapshot pattern for parser staging.

Verdict

REQUEST_CHANGES — The substrate-only services.dag content is careful about single authority (PathTemplate), fail-closed follow-ups, and PR-α/PR-β scope, and nothing in the diff clearly violates INVARIANTS.md / docs/modeling-discipline.md / CODING.md as written. The missing parse corpus manifest refresh is a concrete integration gap tied directly to adding this path under src/v3/std/. After refreshing the manifest (per the ignored helper noted in parse_corpus_manifest.txt), this is likely merge-ready.

CI follow-up: v3 is red on this head, and the scheduled review points to the concrete missing artifact: src/v3/compiler/tests/integration/parse_corpus_manifest.txt was not refreshed after adding src/v3/std/services.dag.

Please run:

cargo test -p v3-compiler refresh_handwritten_parse_snapshot_manifest -- --ignored
cargo test -p v3-compiler parse_stage4_prep::handwritten_parse_snapshot_matches_manifest

Commit the manifest delta, then fold that into the remaining manager checklist: title/body cleanup, focused declaration-shape test, and bootstrap regen/verify if services.dag changes generated snapshots. If the completed v3 log shows a second failure after the manifest issue, handle that too rather than only refreshing the manifest.

  • Comparison: origin/main @ c5521e9b ... review/pr-1246-06c1b5d6 @ 06c1b5d6
  • Thinking: 50s wall

Verdict: APPROVE — src/v3/std/services.dag introduces three carrier types (InputField, RestEndpointBinding, Operation) with no data rows. The doc comments explicitly: (1) reuse PathTemplate from v3.std.effects rather than re-declaring path structure (single authority preserved), (2) use Map<String, InputField> so duplicate input names are unrepresentable by construction (services.dag:90), and (3) name a bounded, tracked dissolution trigger for the producerless-carrier scaffold (PR-β..ω, T-ImpossibleBugs path (ii), MethodTemplateContract precedent). The bootstrap_generated*.rs churn is the expected ID re-shuffle from regeneration. No diff lines violate INVARIANTS.md / docs/modeling-discipline.md / CODING.md / TESTING.md.

Exploratory: InputField {} lands as an empty record reserved for PR-β extension. That's fine and well-justified, but worth keeping an eye on — if PR-β adds a name: String field it would duplicate the map key and break the single-authority story the comment promises; the comment correctly pre-empts this.

  • Thinking: 47s wall

Verdict: APPROVE — type-authority-only PR adds three substrate carriers (InputField, RestEndpointBinding, Operation) in a new v3.std.services module, plus the corresponding manifest line and regenerated bootstrap. The diff is narrowly scoped and the doc comments explicitly address the modeling-discipline concerns the rubric would raise:

  • single-authority for path structure: defers to PathTemplate from v3.std.effects rather than re-declaring (services.dag:18-26).
  • illegal-states-unrepresentable for input-field names: Map<String, InputField> makes duplicate keys unrepresentable; ParamToken.name resolves into the same key set (services.dag:28-37).
  • tracked-debt for the producerless carriers: dissolution trigger named (PR-β..ω fixture rows; ultimate retirement of OperationEffect per T-ImpossibleBugs path (ii)), bounded, and documented (services.dag:7-50).
  • empty InputField {} is justified as a reserved record so PR-β can grow a field without churning Operation.inputs's shape (services.dag:52-61).

No findings against the diff. The bulk of the +/− lines are mechanical regeneration of bootstrap_generated*.rs consistent with adding a new module.

Follow-up on head 589dc188: the manifest + bootstrap artifacts are now present and the latest review approves the carrier shape. Remaining blockers are narrower:

  1. GitHub reports mergeStateStatus: DIRTY. Rebase/merge current origin/main and push a fresh head.
  2. Title/body are still dashboard placeholders. Please update them before merge; body should state this is PR-α type authority only, PR-β..ω fixture rows/accessors/lockstep are Grounding-owned, no bootstrap_fixture_authority row is added, and no test-only bridge is introduced. Include the verification commands run.
  3. Add the focused declaration-shape test from the manager checklist. The PR currently has no test file in the diff. Minimum assertion: Operation, RestEndpointBinding, and InputField resolve; Operation.inputs is Map<String, InputField>; RestEndpointBinding.path points at the existing PathTemplate authority from v3.std.effects; and no data/accessor fixture authority is added in this PR.

After those are in, rerun/let CI run. Shape is accepted; this is now merge hygiene plus the missing ratchet.

Non-blocking — Improvements (fix in-PR if easy, else defer to roadmap)

  • src/v3/std/services.dag Line 3 imports PathTemplate from v3.std.effects, but the live staged module is std.effects; update the import/comment path before fail-closed import enforcement lands (roadmap lane: import hygiene).

✅ No blocking concerns; the carrier now follows the existing PathTemplate and Map authorities.

Second-pair audit from keen-badger-745 — REQUEST_CHANGES on merge readiness, type shape acceptable.

I read head 589dc188 against the #1133 dispatch checklist. The PR-alpha carrier shape now looks structurally sound for wise-tern-480's PR-beta row work:

  • P1 receipt surface: materially present in src/v3/std/services.dag. Operation is anchored as the carrier that dissolves authored OperationEffect rows; RestEndpointBinding.path reuses existing PathTemplate authority instead of declaring a second path model; InputField is keyed by Operation.inputs: Map<String, InputField> rather than duplicating name: String. The receipt is inline rather than labeled Step 1/2/3, but the ancestor/single-authority/primitive-vs-extension reasoning is present.
  • Single-authority discipline: no new PathTemplate/path-token authority remains; it imports the existing effects path carrier. The earlier repeated-string input identity issue is also resolved by the map key shape. I do not see a MethodTemplateContract-style collision in the final carrier set.
  • Fixture-row hostability: data <provider>_operations: List<Operation> can host Anthropic/OpenAI/GitHub rows cleanly. Provider-specific rows remain out of scope, and the type is not Anthropic-specialized.
  • Extension seam: InputField {} is empty but intentionally reserved for later metadata without changing the map shape; RestEndpointBinding can grow body binding later without changing the operation carrier.

Remaining merge blockers are process/ratchet blockers, not a carrier-shape objection:

  1. mergeStateStatus is still DIRTY / conflicting. Merge current origin/main and rerun the checks on a fresh head.
  2. The PR still lacks the focused declaration-shape test requested by the manager: resolve Operation, RestEndpointBinding, InputField; assert Operation.inputs is Map<String, InputField>; assert RestEndpointBinding.path points at the existing PathTemplate authority; assert no data/accessor fixture authority lands in PR-alpha. This is important because PR-beta row authors will depend on this exact shape.
  3. Title/body are still dashboard placeholders; update before merge so the PR itself records PR-alpha type authority only, PR-beta..omega fixture rows/accessors/lockstep as downstream Grounding-owned work, no bootstrap_fixture_authority row, and no test-only bridge.
  4. Scope note: the PR does touch src/v3/compiler/, but the touched files are generated bootstrap/parse-manifest artifacts required by adding a new std file. I do not see hand-authored compiler logic changes.

After those are fixed, I would be comfortable with PR-beta starting from this carrier shape.

Manager follow-up on current head 0d927a14: this still has two merge blockers even if CI finishes green.

  1. Title/body are still the dashboard placeholders. Please update them before merge. The body needs to record: PR-alpha type authority only; PR-beta..omega fixture rows/accessors/lockstep tests are Grounding-owned; no bootstrap_fixture_authority row is added here; no test-only bridge is introduced; and the exact verification commands run.

  2. The focused declaration-shape test is still missing from the file list. Minimum ratchet: Dag::new() or generated std bootstrap resolves Operation, RestEndpointBinding, and InputField; Operation.inputs is Map<String, InputField>; RestEndpointBinding.path resolves to the existing PathTemplate authority; and no data/accessor fixture authority is present in this PR.

The carrier shape itself is accepted. This is now publication hygiene plus the missing ratchet before PR-beta Grounding work starts.

CI diagnosis for current head 0d927a14: v3 fails at bootstrap freshness, not in the tests themselves.

Failing step:

cargo run -p v3-compiler --features bootstrap-regen-fresh --bin regen_bootstrap -- --verify

Failure:

bootstrap_generated.rs: committed snapshot does not match fresh compile from .dag sources
first differing byte index: 1112
on_disk_len=1390568, expected_len=1392548

So the branch currently has services.dag + parse manifest, but the generated bootstrap snapshots are stale or absent for this head. Please run and commit:

cargo run -p v3-compiler --features bootstrap-regen-fresh --bin regen_bootstrap
cargo run -p v3-compiler --features bootstrap-regen-fresh --bin regen_bootstrap -- --verify

Then keep the prior merge blockers in the same patch stack: update title/body and add the focused declaration-shape test. CI will stay red until the bootstrap snapshot delta is present.

Findings

None. The substantive change is a new services.dag plus parse-corpus manifest and regenerated bootstrap tables. Nothing in the diff contradicts the cited rubric in a way that needs a fix here.

Verdict

APPROVE — PR-α is explicitly type-authority only: RestEndpointBinding reuses PathTemplate from v3.std.effects instead of a second path model (P2 / single authority), Operation.inputs is Map<String, InputField> so duplicate input names are structurally ruled out (modeling-discipline “illegal states unrepresentable”), and deferred fail-closed checks (ParamToken.name vs map keys, body shape) are named to fixture load in PR-β with bounded scope in the header comments (tracked bridge, not silent drops). The // 🟢 TERMINAL … notes on the new types satisfy the spirit of coproduct classification for this layer even though the checklist in docs/modeling-discipline.md is phrased for new Rust enums. Bootstrap churn is mechanical fallout from the new std module.

Current #1246 status: v3 and ci are now green after the bootstrap regen, but GitHub reports mergeStateStatus: DIRTY after main advanced.

Please rebase/merge latest origin/main and preserve the regenerated bootstrap artifacts. The existing merge blockers still apply after the rebase:

  1. Update the PR title/body from dashboard placeholders.
  2. Add the focused declaration-shape test for Operation, RestEndpointBinding, InputField, Operation.inputs: Map<String, InputField>, RestEndpointBinding.path -> PathTemplate, and no fixture-row/accessor authority in PR-alpha.

Current head 271f5c3d5b550cc664031ffeca22fc9fe0e8194b: rebase resolved mergeability, but v3 is failing for stale generated artifacts.

Two signals from the log:

  • parse_stage4_prep::handwritten_parse_snapshot_matches_manifest still fails.
  • All services_carrier_shape_test shape checks fail because the full bootstrap is missing the new services declarations:
    • InputField missing from full bootstrap
    • Operation missing from full bootstrap
    • RestEndpointBinding missing from full bootstrap

That means src/v3/std/services.dag is in the parse corpus, but the committed bootstrap snapshots do not carry the declarations after the post-#1227 rebase. Please regenerate, not only verify:

cargo run -p v3-compiler --features bootstrap-regen-fresh --bin regen_bootstrap
cargo run -p v3-compiler --features bootstrap-regen-fresh --bin regen_bootstrap -- --verify
cargo test -p v3-compiler refresh_handwritten_parse_snapshot_manifest -- --ignored
cargo test -p v3-compiler --test integration services_carrier_shape_test -- --nocapture
cargo test -p v3-compiler --test integration parse_stage4_prep::handwritten_parse_snapshot_matches_manifest -- --nocapture

Commit the resulting bootstrap_generated* and parse_corpus_manifest.txt deltas. No carrier-shape change indicated by this run.

  • Thinking: 58s wall

Findings

None. The diff adds src/v3/std/services.dag with explicit 🟢 TERMINAL scope notes, upstream reuse of PathTemplate and DeclarationRef, Map<String, InputField> for single-authority names, and documented PR-β..ω triggers for fixture rows and fail-closed checks — aligned with P1/P2/P5 and modeling-discipline practices (illegal states avoided where modeled, no parallel path authority). Regenerated bootstrap_generated.rs (and sibling) embeds the new Declaration rows, which satisfies the spirit of P2’s “realization + generated materialization” for this layer (the seed graph is generated from the .dag surface). The integration ratchet in services_carrier_shape_test.rs is behavior-oriented structural shape checks, consistent with TESTING for “full bootstrap is the unit” here.

Verdict

APPROVE — Narrow PR-α substrate carriers, coherent authority story, regen + targeted tests; no concrete rubric violations found in the diff.

  • Thinking: 84s wall

Findings:

  • src/v3/std/services.dag:115 uses bare DeclarationRef for Operation.callable while the surrounding comment acknowledges it can point at non-callable declarations and defers the fail-closed check to PR-β. For a new substrate carrier, this violates P2 / modeling-discipline “illegal states unrepresentable” and “API-level enforcement”: the substrate now admits invalid Operation values by construction. The nearby MethodRef precedent wraps the broad reference as a scaffold with a named refinement trigger; this PR should use the same kind of typed callable reference or otherwise make the callable target constraint structural.

Verdict: REQUEST_CHANGES. The carrier shape is otherwise narrow and well-tested, but the new substrate surface locks in an over-broad authority field for operation identity.

  • Thinking: 50s wall

Findings

None. The new carriers reuse upstream authority (PathTemplate from std.effects, HttpMethod from std.types, DeclarationRef via CallableRef), avoid parallel name: String on operations, use Map<String, InputField> so duplicate input names are structurally excluded, and document PR-β fail-closed checks where the type system cannot yet refine DeclarationRef. CallableRef is explicitly classified 🟡 with a named dissolution trigger (#1175), matching docs/modeling-discipline.md. New integration tests are scoped to declaration shape, registered in the SG-0 census, and match TESTING.md guidance for integration-layer structural gates.

Verdict

APPROVE — Diff is focused: services.dag plus a shape ratchet test, wiring, manifest, and regenerated bootstrap. No concrete violations of the referenced invariants or coding/testing discipline surfaced in the reviewed diff.

Exploratory observations (optional)

  • In services_carrier_shape_test.rs, the module doc (around lines 13–15) and the operation_carries_only_callable_inputs_endpoint failure message (around lines 99–101) say callable: DeclarationRef; the substrate field is CallableRef. Worth aligning wording so fixture authors are not pointed at the wrong type name (cosmetic only).

1. Summary

PR #1246 introduces the PR-α substrate carrier surface for services: InputField, RestEndpointBinding, CallableRef, and Operation in src/v3/std/services.dag. The mechanism is deliberately declaration-only: no provider operation rows are populated yet, and the new Operation shape establishes a future single authority for deriving operation effects from a callable reference plus REST method/path/input facts. The load-bearing modeling choices are that RestEndpointBinding.path reuses std.effects::PathTemplate instead of declaring a services-local path model, Operation.inputs is keyed as Map<String, InputField> instead of carrying duplicate name fields, and Operation.callable uses a typed wrapper over DeclarationRef rather than a free-form operation name. The generated bootstrap files and parse manifest are downstream regen, while services_carrier_shape_test.rs ratchets the new carrier shapes and asserts PR-α does not smuggle in data rows.

2. Invariant categories

  1. LAYER MODEL (substrate vs implementation).

Compliant — this is substrate-facing: src/v3/std/services.dag:114-126 adds type Operation { callable: CallableRef; inputs: Map<String, InputField>; endpoint: RestEndpointBinding }, and the fields are substrate carrier facts rather than Rust implementation state. The PR also avoids creating a duplicate path substrate by importing PathTemplate at src/v3/std/services.dag:3-4 and explaining that path-structure authority stays upstream at src/v3/std/services.dag:13-24; that matches the P1/P2 rule that new constructs need declared grounding and single authority. chatgpt-review-b4d30398-3ba9-4f…

  1. INVARIANTS.md + modeling-discipline.md.

Compliant — single-authority metadata is handled concretely: src/v3/std/services.dag:26-34 makes input field names the Map<String, InputField> keys, not duplicated fields, and src/v3/std/services.dag:107-112 says display/lens operation names derive from callable.decl, not a parallel name: String. Fail-closed residuals are also bounded: CallableRef admits any DeclarationRef for now, but src/v3/std/services.dag:88-96 names the future fixture-load callable-target check and the #1175 refinement-typing dissolution trigger. The relevant modeling discipline is structural single authority / API-level enforcement over convention; the wrapper improves the field-level contract even though full target refinement is deferred. chatgpt-review-b4d30398-3ba9-4f…

  1. CODING.md.

Compliant — the hand-written Rust added in src/v3/compiler/tests/integration/services_carrier_shape_test.rs:23-56 uses small free helper functions over &Dag (conj_field_labels, conj_field_ty, decl_id_by_name) rather than adding methods or hidden state. That follows the project’s data + free-functions style and keeps the dependency list explicit. chatgpt-review-ec7f42bd-db74-46…

  1. TESTING.md.

Compliant — the PR adds a focused integration ratchet and wires it through src/v3/compiler/tests/integration.rs:140-142. The tests are behavior/shape claims against the generated bootstrap surface: src/v3/compiler/tests/integration/services_carrier_shape_test.rs:59-70 ratchets InputField as empty, :73-89 ratchets RestEndpointBinding fields, :92-109 ratchets Operation fields, :112-156 ratchets CallableRef, :159-205 ratchets Map<String, InputField>, :208-235 ratchets upstream PathTemplate, and :238-261 ratchets “no data rows in PR-α.” The full-bootstrap integration layer is justified here because the subject is whether the declared std surface is actually present in the generated bootstrap, not a narrow compiler helper. chatgpt-review-aacb1252-7a03-48…

  1. LOCKED DESIGN DECISIONS.

Compliant — the diff references locked-ish / prior design lanes but does not alter them: src/v3/std/services.dag:17-24 explicitly preserves std.effects::PathTemplate/std.http_path authority, and src/v3/std/services.dag:49-55 positions these carriers as a prerequisite to retiring authored OperationEffect later rather than changing that retirement in this PR. No divergence from a locked design decision appears in the diff.

  1. TRACKED vs UNTRACKED DEBT.

Compliant — the only transitional shape is CallableRef, and it is tracked: documentation exists at src/v3/std/services.dag:84-96, bounds are stated as PR-α fixture-free type authority plus future fixture-load validation, and the named dissolution trigger is “the same #1175 substrate-level refinement-typing landing that retires MethodRef retires this wrapper” at src/v3/std/services.dag:94-96. The new hand-written test file is also acknowledged in the SG-0 census at src/v3/compiler/tests/integration/sg0_census_test.rs:351, so the Rust-test scaffold is visible rather than hidden. The P5 scaffold rule requires explicit dissolution paths for transitional surfaces, which this PR provides for the substrate wrapper. chatgpt-review-b4d30398-3ba9-4f…

3. Verdict

APPROVE. The PR introduces substrate carrier types, but the modeling is narrow, single-authority, and well-ratcheted: path structure is reused, input names are keyed, callable identity is typed, provider data rows are explicitly deferred, and the only residual wrapper has a named dissolution trigger. I did not find a diff-citable invariant violation.

Verdict: APPROVE

Diff is narrowly scoped and the new substrate carriers in src/v3/std/services.dag are documented with grounding, single-authority choices, and dissolution triggers where needed. I found no concrete violations of the pinned invariants, modeling discipline, coding, or testing guidance.

Verification: cargo test -p v3-compiler --test integration services_carrier_shape_test -- --nocapture passed, 7/7 tests.

Findings

None. The substantive change adds src/v3/std/services.dag with explicit single-authority choices (PathTemplate from std.effects, Map<String, InputField> for key uniqueness, no duplicate name: String), a transitional CallableRef that states a concrete dissolution trigger (aligned with docs/modeling-discipline.md scaffold rules), and enum/record-style classifications in comments. The integration ratchet in services_carrier_shape_test.rs pins those shapes against the full bootstrap in a way that matches TESTING.md’s “pipeline/bootstrap is the unit when the contract is global std wiring” spirit.

Verdict

APPROVE — The diff is narrowly scoped to PR-α carriers plus regen churn and a shape ratchet; nothing here clearly violates INVARIANTS.md, docs/modeling-discipline.md, CODING.md, or TESTING.md in a way that requires changes. (Per your rules: anything about P5’s PR-description receipt lives outside this diff, so it is not cited as a finding.)

Exploratory observations (optional)

  • operation_callable_field_is_callable_ref_wrapper pins CallableRef’s declaring file to src/v3/std/services.dag (services_carrier_shape_test.rs ~127–131). That is deliberate for authority localization but will force test updates if the type ever moves to a shared module — a reasonable tradeoff for a ratchet.
  • Each test builds generated_full_bootstrap_dag() independently; if CI time grows, consolidating fixtures could be a later optimization (non-blocking).

1. Story of the diff

This PR introduces v3.std.services as a type-authority substrate surface for service operations: it adds InputField, RestEndpointBinding, CallableRef, and Operation without adding provider fixture/data rows yet. The core modeling choice is that operation identity is carried by a typed CallableRef edge, REST path shape is delegated to the existing std.effects.PathTemplate authority, and input names live as Map<String, InputField> keys instead of being duplicated inside each field record (src/v3/std/services.dag:17-37, src/v3/std/services.dag:86-126). The generated bootstrap files and parse manifest are regenerated to include the new std file, and the PR adds a focused carrier-shape integration ratchet to lock the intended PR-α scope before PR-β fixture rows arrive (src/v3/compiler/tests/integration/parse_corpus_manifest.txt:45, src/v3/compiler/tests/integration/services_carrier_shape_test.rs:1-23).

2. Invariant categories

  1. LAYER MODEL substrate vs implementation — Compliant. This is substrate work: Operation and friends are new .dag carrier types. The PR keeps authority narrow: RestEndpointBinding.path imports existing PathTemplate instead of declaring a parallel path model (src/v3/std/services.dag:17-26, src/v3/std/services.dag:81-84), and Operation.callable uses the dedicated CallableRef wrapper rather than an untyped name string (src/v3/std/services.dag:102-126).
  2. INVARIANTS.md + modeling-discipline.md — Compliant. Boundary Discipline / single authority is handled directly: input-field names are keyed by Operation.inputs: Map<String, InputField>, while InputField stays empty specifically to avoid a duplicate name: String authority (src/v3/std/services.dag:28-37, src/v3/std/services.dag:56-64). Fail-closed is also explicitly deferred to the first fixture-load boundary rather than silently accepting bad rows now: ParamToken.name and callable-target checks are named as PR-β fixture-load validations (src/v3/std/services.dag:31-34, src/v3/std/services.dag:90-98).
  3. CODING.md — Compliant. The Rust added here is test-only helper code with small data-query helpers (conj_field_labels, conj_field_ty, decl_id_by_name) and structured assertions over TypeConnective, not a new object/method surface or hidden mutable state (src/v3/compiler/tests/integration/services_carrier_shape_test.rs:25-58). The production substrate itself is declarative .dag data, which is consistent with the repo’s data-first style.
  4. TESTING.md — Compliant. The PR adds a behavior/shape ratchet at the appropriate level: it verifies the public bootstrap declaration surface, not incidental generated IDs. The tests pin the intended carrier contracts: empty InputField, exact RestEndpointBinding and Operation fields, CallableRef wrapping, Map<String, InputField>, reuse of std.effects.PathTemplate, and absence of PR-α data rows (src/v3/compiler/tests/integration/services_carrier_shape_test.rs:60-261). The module is wired into integration tests and SG-0 census (src/v3/compiler/tests/integration.rs:141-142, src/v3/compiler/tests/integration/sg0_census_test.rs:352).
  5. LOCKED DESIGN DECISIONS — Compliant. The diff references prior locked/precedent surfaces but does not diverge from them: PathTemplate remains upstream in std.effects, and the new service file explicitly avoids re-declaring path structure (src/v3/std/services.dag:17-26). The CallableRef wrapper is framed as mirroring MethodRef and sharing the same refinement-typing gap rather than claiming that gap is solved in this PR (src/v3/std/services.dag:86-98).
  6. TRACKED vs UNTRACKED DEBT — Compliant. The one obvious temporary shape is CallableRef: it documents the residual illegal state, bounds enforcement to PR-β fixture load, and names the dissolution trigger as the same feat(v3): add MethodTemplateContract substrate carrier #1175 refinement-typing landing that retires MethodRef (src/v3/std/services.dag:86-98). PR-α’s no-data-row scope is also bounded and tested: the file comment says fixture rows are PR-β..ω scope, and the new test rejects any value_body authored from services.dag (src/v3/std/services.dag:10-15, src/v3/compiler/tests/integration/services_carrier_shape_test.rs:234-261).

3. Verdict

APPROVE. The PR is substrate-facing, but the new carriers are intentionally narrow, single-authority, and accompanied by a focused shape ratchet. I did not find a changed diff line that violates the layer model, fail-closed discipline, locked design decisions, or tracked-debt requirements.

* chore: apply cargo fmt

* test(grounding): wire ParamToken.name → Operation.inputs boundary check (vacuous on Messages)

Per codex non-blocking finding on PR #1252: header claimed the
ParamToken.name resolution check is wired, but no actual assertion
existed. Adds anthropic_operations_param_tokens_resolve_to_input_keys
which walks every row's path tokens and asserts each ParamToken's
name is a present key in the operation's input map.

Vacuous on the Phase 1 Messages pilot (/v1/messages is pure literal
segments), but rows with path variables inherit the discipline by
construction. Header text tightened to make the structural-wired vs
runtime-active distinction explicit.

1. Story of the diff

This PR introduces v3.std.services as an authority-only substrate surface for service operations: an Operation has a canonical name, a uniquely keyed inputs: Map<String, InputField>, and a RestEndpointBinding that points to an HTTP method plus the existing PathTemplate authority from v3.std.effects (src/v3/std/services.dag:1-95). The file is intentionally data-free in this PR: provider fixture rows are deferred, while the carrier types establish the shape future fixture rows will inhabit (src/v3/std/services.dag:6-11). The key modeling move is to avoid inventing a second path representation locally; endpoint paths reuse PathTemplate, and input-name identity is scoped by the map key rather than duplicated inside InputField (src/v3/std/services.dag:13-34, src/v3/std/services.dag:54-61). The parse corpus manifest is updated to include the new std file (src/v3/compiler/tests/integration/parse_corpus_manifest.txt:43).

2. Invariant categories

  1. LAYER MODEL (substrate vs implementation).

Compliant — this is substrate/type-authority work, and it keeps the layer narrow: RestEndpointBinding.path imports the existing PathTemplate authority instead of re-modeling path tokens locally (src/v3/std/services.dag:13-22, src/v3/std/services.dag:67-73). That matches the single-authority substrate discipline in the invariants. chatgpt-review-ff415cf4-b33a-49…

  1. INVARIANTS.md + modeling-discipline.md.

Compliant — boundary discipline / single-authority metadata is handled explicitly: Operation.inputs is keyed as Map<String, InputField>, and InputField deliberately omits a duplicate name field that could drift from the map key (src/v3/std/services.dag:24-34, src/v3/std/services.dag:54-61, src/v3/std/services.dag:89-93). This directly follows the “one canonical location” pattern. chatgpt-review-33bca983-177f-4e…

  1. CODING.md.

Compliant — no Rust implementation code or methods are introduced; the diff is declarative .dag data modeling. The shape is data-first and uses typed fields (HttpMethod, PathTemplate, Map<String, InputField>) rather than behavior hidden behind methods, consistent with the data + functions convention. chatgpt-review-53d99aa4-3d87-4a…

  1. TESTING.md.

Compliant — for this PR’s scope, the relevant test receipt is parse-corpus coverage: the new src/v3/std/services.dag is added to parse_corpus_manifest.txt (src/v3/compiler/tests/integration/parse_corpus_manifest.txt:43). Since there are no fixture rows or consumers yet, behavior-level tests would be premature; fixture-load validation is explicitly deferred to the first provider data row (src/v3/std/services.dag:28-31).

  1. LOCKED DESIGN DECISIONS.

Compliant — the diff does not appear to alter a locked surface; it names prior/adjacent design precedent and keeps path structure on the existing PathTemplate authority rather than creating a divergent services-private path model (src/v3/std/services.dag:13-22).

  1. TRACKED vs UNTRACKED DEBT.

Compliant — the staged nature is documented and bounded: PR-α is “type-authority pass only,” provider operation rows are PR-β..ω scope, and the future consumer/dissolution path is named for analyze_workflow / analyze_parallelism and eventual OperationEffect retirement (src/v3/std/services.dag:6-11, src/v3/std/services.dag:41-52). I do not see an untracked TODO or temporary parallel representation introduced in the changed lines.

3. Verdict

APPROVE — The PR is a small substrate carrier addition with the important authority choices called out in the diff itself: path shape remains upstream, input identity is keyed once, and fixture/consumer follow-up is bounded rather than silently implied. No blocking invariant issue surfaced in the changed lines.

1. Story of the diff

This PR introduces src/v3/std/services.dag as a substrate-level carrier surface for service operations, but deliberately stops at type authority. The new model defines three carriers: InputField, RestEndpointBinding, and Operation; it keeps REST path structure out of services by importing PathTemplate from std.effects, and it keeps callable identity structural by using DeclarationRef instead of adding a free-form operation name (src/v3/std/services.dag:3-5, src/v3/std/services.dag:23-36, src/v3/std/services.dag:91-118). The load-bearing modeling move is that Operation.inputs is Map<String, InputField>, making input names the map key rather than a duplicated field inside InputField (src/v3/std/services.dag:27-36, src/v3/std/services.dag:115-117).

The rest of the diff wires that new std file into generated bootstrap state and parse coverage, then adds a structural integration ratchet. services_carrier_shape_test.rs locks the carrier shapes, verifies Operation.callable resolves to DeclarationRef, verifies Operation.inputs is Map<String, InputField>, verifies RestEndpointBinding.path points to std.effects::PathTemplate, and asserts PR-α has not added fixture/data rows in services.dag (src/v3/compiler/tests/integration/services_carrier_shape_test.rs:1-22, src/v3/compiler/tests/integration/services_carrier_shape_test.rs:107-180, src/v3/compiler/tests/integration/services_carrier_shape_test.rs:208-233). Generated bootstrap files and the parse manifest update are mechanical receipts for that new declaration surface.

2. Invariant categories

  1. LAYER MODEL — Compliant. This does touch substrate-facing std declarations, and the PR keeps the new facts as carrier types rather than Rust implementation state: Operation carries callable, inputs, and endpoint as declared fields (src/v3/std/services.dag:112-118). The path authority is explicitly upstream, not redeclared locally (src/v3/std/services.dag:23-25, src/v3/std/services.dag:75-78).
  2. INVARIANTS.md + modeling-discipline.md — Compliant. Single-authority metadata is handled by making the operation-to-callable edge callable: DeclarationRef and deriving display/lens names from that edge rather than adding name: String (src/v3/std/services.dag:91-104). Illegal-state reduction is handled by using Map<String, InputField> for input-name uniqueness and by keeping the canonical name out of InputField (src/v3/std/services.dag:27-36, src/v3/std/services.dag:59-66). Fail-closed fixture validation is deferred, but the deferral is named and bounded to PR-β fixture load (src/v3/std/services.dag:31-34, src/v3/std/services.dag:106-111).
  3. CODING.md — Compliant. The new Rust is test-only and uses small free helper functions over Dag (conj_field_labels, conj_field_ty, decl_id_by_name) rather than adding methods or hidden state (src/v3/compiler/tests/integration/services_carrier_shape_test.rs:29-58). The production modeling change is in .dag declarations; generated bootstrap churn is mechanical.
  4. TESTING.md — Compliant. The PR adds focused structural tests for the new substrate surface and wires them into integration test dispatch (src/v3/compiler/tests/integration.rs:137-140). The tests are behavior/shape ratchets over the published declaration interface, not implementation-layout assertions: e.g. operation_inputs_field_is_map_string_to_input_field checks the declared Map<String, InputField> carrier contract (src/v3/compiler/tests/integration/services_carrier_shape_test.rs:132-176), and services_dag_authors_no_data_rows_in_pr_alpha guards the PR-α scope boundary (src/v3/compiler/tests/integration/services_carrier_shape_test.rs:208-233).
  5. LOCKED DESIGN DECISIONS — N/A. The diff references prior design/PR context, but it does not edit a locked design document or alter a locked design surface directly. The closest relevant decision is honored by reusing std.effects::PathTemplate rather than introducing a services-local path schema (src/v3/std/services.dag:23-25, src/v3/compiler/tests/integration/services_carrier_shape_test.rs:179-206).
  6. TRACKED vs UNTRACKED DEBT — Compliant. The staged pieces are explicitly bounded: no data rows in PR-α (src/v3/std/services.dag:8-15), fixture rows are PR-β..ω scope (src/v3/std/services.dag:10-15), fixture-load checks are named for ParamToken.name and callable.decl (src/v3/std/services.dag:31-34, src/v3/std/services.dag:106-111), and the downstream dissolution target is named as deriving OperationEffect from loaded Operation records so authored lane2_workflow / OperationEffect can retire (src/v3/std/services.dag:44-54). The SG0 census is also updated for the new hand-authored test file (src/v3/compiler/tests/integration/sg0_census_test.rs:348-351).

3. Verdict

APPROVE. The PR introduces substrate carrier types in a narrow, well-ratcheted shape: identity is typed, path structure is reused from the existing authority, input names have one canonical location, and the “types now / rows later” staging is documented and tested. I did not find a diff-local invariant violation that warrants comments or changes.
