Authority

• Substrate escalation session/lively-ferret-24 · lively-ferret-24 #856 (R2 impossible-bugs / extdeps P1 bypasses).
• Worker dispatch session/proud-gull-252 · proud-gull-252 #867 (extdeps typed-primitive-consumption / structural-coverage-gap lane).
• Design gunbc Director #808 (T-ImpossibleBugs unenumerated effects — closed-system framing; no parallel OperationEffect / SideEffects / readonly / idempotent tags on this lane).

Shared Rule For Residues

• Close structurally where typed primitive consumption is honest on this slice.
• Otherwise name structural-coverage-gap evidence with a downstream closure trigger.
• Do not replace residues with hand-authored effect taxonomy or modifier facts.

P1 Bypass Before / After

Surface	Before	Current disposition
OpenAI ChatCompletion	messages: Json plus output path extraction	messages: List<OpenAiChatMessage> with `OpenAiChatMessageRole = System
Anthropic Messages	messages: Json plus output path extraction	messages: List<AnthropicChatMessage> where the outer variant is the role discriminator: UserMessage { content: List<AnthropicUserContentBlock> } or AssistantMessage { content: List<AnthropicAssistantContentBlock> }. User rows can carry text/tool results; assistant rows can carry text/tool-use requests. Wire role and type keys are not caller-authored model state.
github_token	Returned token material while discarding modeled scope/expiry facts	Returns GitHubSecretManagerPat { token } only. The carrier now lives in dsl/extdeps/github/auth.dag with the Secret Manager acquisition function, not in the GitHub core provider model. No scopes: [] and no expires_at: none; unknown metadata is not encoded as observed-empty metadata.

Gap Receipts

OpenAI / Anthropic outputs still use from "..." path projection. This slice names that residue as queryable structural-coverage-gap data:

• structural_coverage_gap_openai_chat_completion_outputs in dsl/extdeps/llm/openai.dag
• structural_coverage_gap_anthropic_messages_outputs in dsl/extdeps/llm/anthropic.dag

Closure trigger: rest_typed_response_body.

Request wire serialization is also named explicitly because the Rust emitter's default enum/sum serde may not match provider wire contracts:

• structural_coverage_gap_openai_chat_request_messages_wire
• structural_coverage_gap_anthropic_messages_request_wire

Closure trigger: rest_request_wire_serde_alignment.

Anthropic message/content variants deliberately do not expose caller-writable role or type discriminator fields. structural_coverage_gap_anthropic_messages_request_wire names the remaining obligation: the future serde alignment closure must emit role strings and flat content type wire keys from UserMessage / AssistantMessage and their role-specific content variants.

Anthropic tool-result content is intentionally a narrow text-result slice in this PR. Non-string/nested/image tool-result content is explicitly gap-carried by structural_coverage_gap_anthropic_tool_result_full_content_surface with closure trigger anthropic_tool_result_full_content_surface.

Coproduct Classification

• AnthropicChatMessage is classified as a 🟢 terminal provider-domain coproduct for modeled Messages row roles.
• AnthropicUserContentBlock and AnthropicAssistantContentBlock are classified as 🟢 terminal provider-domain coproducts for role-legal content rows in the modeled slice.
• OpenAiChatMessageRole is classified as a 🟢 terminal provider-domain coproduct for the modeled narrow text-message row.
• These classifications do not claim request JSON serialization or full provider content coverage is complete; residues are gap-carried as above.

TextBlock / Content Blocks

Anthropic user text is modeled as UserTextBlock { text: String }; assistant text is modeled as AssistantTextBlock { text: String }. Tool results are currently UserToolResultBlock { tool_use_id, content: String, is_error }, with richer tool-result content gap-carried. Call sites in dsl/gunbc/tools/review.dag and src/v2/tests/src/pipeline.rs use UserMessage { content: [UserTextBlock { text: ... }] }. The wire "type":"text" discriminator belongs to rest_request_wire_serde_alignment.

Optional Timestamp? / none

Not used on the Secret Manager PAT path after the carrier split. Elsewhere, none for optionals matches existing repo precedent.

Verification

• git diff --check passed after the latest Secret Manager carrier / tool-result gap fix.
• Local cargo checks could not run in the agent environment because cargo is not installed. GitHub Actions should supply fmt, ci, v3, and self_host_ratchet receipts for this PR.

Manager review — keep this draft; do not mark ready yet.

This PR is currently the same head SHA as closed #895 (6f494af68ad04d179d6d8b5a7669abef0c70f2a6), so the blockers that caused #895 to close are still present:

1. github_token still fabricates token facts. Secret Manager returns only the PAT; scopes: [] means "observed no scopes", not "unknown/unmodeled scopes". This needs either a narrower carrier for PAT-only credentials or an explicit structural-coverage-gap/unknown-metadata shape. Do not encode unknown as empty.

2. Provider message shapes are still too broad. OpenAiChatMessage.role: Role admits Tool without tool-call fields and admits System/Tool shapes with content: String only; AnthropicChatMessage.role: Role admits System/Tool even though this surface should be user/assistant message rows. Use provider-specific role/message carriers or a deliberate gap carrier; the shared Role union is not narrow enough here.

3. The new Anthropic call sites use TextBlock { type: "text", text: ... }, but AnthropicContentBlock.TextBlock is declared as TextBlock { text: String }. The type field is not declared in the local DSL shape.

4. Output path extraction / JSON-path residue still needs a clear disposition. The lane brief is not just "replace Json inputs"; it must state what remains non-derivable and how that is carried as structural-coverage-gap evidence.

5. PR body is still the dashboard default. Before ready, fill it with session/lively-ferret-24 · lively-ferret-24 #856/session/lively-wren-457 · lively-wren-457 #857/gunbc Director #808 context, the no-fabricated-facts rule, the concrete P1 bypass receipt, DB-8/stage0/test status, and any intentional residual gap.

Please push a real corrective commit on this worker branch or close this duplicate draft. Reopening the same blocked head under a new PR number does not satisfy the ready/close audit.

BLOCKING (6)

Root Cause

• dsl/extdeps/github/auth.dag Secret Manager token acquisition lacks GitHub scope/expiry evidence → keep the raw token carrier or model known/unknown scope and expiry evidence explicitly.
• dsl/extdeps/llm/anthropic.dag Anthropic request messages need provider-specific role and content-block wire carriers → model the internally type-discriminated block products before replacing Json.
• dsl/extdeps/llm/openai.dag OpenAI chat messages are a provider-specific union keyed by role with different required fields → model those variants instead of a single product over the shared Role.

⚠️ The PR moves in the right direction by removing opaque Json-string messages, but the new carriers need faithful provider-specific wire shapes before landing.

[briansrls]

Verification vs blocking inline review (relay may reference older SHA 6f494af6; current head 0a98c73):

1. dsl/extdeps/github/auth.dag — No scopes: []. github_token returns GitHubSecretManagerPat with { token: cred.token } only (github.dag documents P3 / absent-metadata split from GitHubAuthToken).

2. dsl/extdeps/llm/anthropic.dag — AnthropicChatMessage.role is AnthropicMessagesRole (User | Assistant only), not Role. System is not representable in messages[].

3. dsl/extdeps/llm/openai.dag — OpenAiChatMessage.role is OpenAiChatMessageRole (System | User | Assistant only), not shared llm.Role; no Tool + string-content hole on this carrier.

4. TextBlock — Variant is TextBlock { type: String, text: String }; review.dag and pipeline.rs literals include type: \"text\" consistently.

5. Output path extraction — Still present on outputs; gap-carried via structural_coverage_gap_*_outputs data in the same modules; trigger rest_typed_response_body.

Re: inline at dsl/extdeps/llm/anthropic.dag:93 (Anthropic Messages roles)

Verified on current HEAD of session/proud-gull-252: this is not role: Role.

• AnthropicMessagesRole is defined as User | Assistant only (L92–93). System is not a member; it remains the operation’s top-level system field.
• AnthropicChatMessage uses role: AnthropicMessagesRole (L96–98), so System / Tool from extdeps.llm.llm::Role are unrepresentable on messages[].

The relay text matches an older revision where AnthropicChatMessage still used shared Role; that bypass is already removed here. API reference: Messages examples — user/assistant in messages, system separate.

[briansrls]

Scheduled api-review (sha:6f494af6) vs current HEAD (f9015dd10)

That review predates the landed corrections. Root-cause mapping at f9015dd10:

api-review root cause	Current disposition
Secret Manager token lacks scope/expiry evidence	GitHubSecretManagerPat { token } only in dsl/extdeps/github/auth.dag; GitHubAuthToken kept for paths that actually carry scopes/expiry (github.dag comment: no fabricated empty metadata / P3).
Anthropic messages need provider-specific role + content	AnthropicMessagesRole = User | Assistant; AnthropicChatMessage + AnthropicContentBlock with declared TextBlock { type, text }. Json messages input removed.
OpenAI chat messages union by role	OpenAiChatMessageRole = System | Developer | User | Assistant (not llm.Role); narrow content: String product. Tool / function / multimodal still gap-carried: structural_coverage_gap_openai_chat_message_full_api_surface.
Wire-faithful shapes before landing	Outputs: structural_coverage_gap_*_outputs → rest_typed_response_body. Anthropic request serde vs wire: structural_coverage_gap_anthropic_content_block_request_wire → rest_request_wire_serde_alignment (explicit, not silent).

Earlier thread at 0a98c73 was accurate except OpenAI roles: Developer was added in f9015dd; use System \| Developer \| User \| Assistant (not “Assistant only”).

Net: direction matches review; blocking items from 6f494af6 are addressed or explicitly gap-named per #808 / #856 — not deferred silently.

[briansrls]

Worker verify (current session/proud-gull-252 / f9015dd10) — Anthropic Messages roles

Matches your note; no code change.

Line anchors drifted after gap-receipt edits: AnthropicMessagesRole is now L95 (User | Assistant), AnthropicChatMessage.role: AnthropicMessagesRole L99–101. Still not extdeps.llm.llm::Role; System/Tool remain unrepresentable on messages[] (system stays top-level system on Messages).

[briansrls]

Worker cross-check vs table (HEAD f9015dd10)

Re-read sources: all four disposition rows and the Developer / 0a98c73 footnote match the tree — no further commit.

Spot-check: github_token → GitHubSecretManagerPat only; messages typed on both LLM ops; gap data rows present for outputs + OpenAI full coproduct + Anthropic serde/wire alignment as named in the table.

[briansrls]

Re: line anchors (f9015dd10, unchanged)

Substance unchanged. Tiny anchor fix: AnthropicChatMessage is the product L99–102 (role is L100, content L101, closing } L102). AnthropicMessagesRole remains L95 (User | Assistant).

Still not llm.Role; no code change.

Re: Codex inline anthropic.dag:124 — typed messages vs Anthropic wire

Finding is directionally correct: .dag types model the logical roles/blocks, but REST serde_json::json! bodies still rely on the v2 Rust emitter’s default serde shapes for unit enums / sum types. Those are not guaranteed to match Anthropic’s wire (role as plain "user" / "assistant", content[] as flat {"type":"text",...} objects per Messages API).

We already carried a generic gap; dc113a170 tightens receipts:

• structural_coverage_gap_anthropic_messages_request_wire — explicit residues for role string encoding + flat type-keyed content objects (closure rest_request_wire_serde_alignment).
• structural_coverage_gap_openai_chat_request_messages_wire — same class of issue for OpenAiChatMessageRole string roles on Chat Completions.

So: not dismissed as stale — it is a real wire/serde alignment debt, explicitly gap-named (not patched with effect tags). Full fix belongs in rest_request_wire_serde_alignment (emitter / transport encoding), not silent claims in extdeps alone.

BLOCKING (2)

Root Cause

• dsl/extdeps/llm/anthropic.dag provider role closed set was introduced as substrate without a dissolution receipt → add a terminal/scaffold/dissolve classification comment at the declaration.
• dsl/extdeps/llm/openai.dag provider role closed set was introduced as substrate without a dissolution receipt → add a terminal/scaffold/dissolve classification comment at the declaration.

Non-blocking — Strengths

• dsl/extdeps/llm/anthropic.dag The Messages role/system split matches https://docs.anthropic.com/en/api/messages and the remaining request-wire serde gap is named.
• dsl/extdeps/llm/openai.dag The narrow text-message carrier includes developer and names the missing full-surface Chat Completions cases from https://platform.openai.com/docs/api-reference/chat/create-chat-completion.

⚠️ Prior concerns are addressed, but the two new substrate coproducts need dissolution receipts before landing.

[briansrls]

Manager disposition for queued review on current head dc113a1703c771f60752f89782be513d4b158df9:

The two queued blockers are valid and narrowly scoped. AnthropicMessagesRole and OpenAiChatMessageRole are new provider-specific closed sets, but neither declaration carries the required coproduct dissolution receipt/classification. Please push a worker-owned fix commit adding 🟢/🟡/🔴 classification comments at both declarations.

Expected shape: classify each role set explicitly rather than leaving reviewers to infer it. If they are terminal provider wire/domain authority for the currently modeled narrow request surface, say that. Also preserve the existing distinction that request wire serialization remains gap-carried under rest_request_wire_serde_alignment, and OpenAI's full message coproduct remains gap-carried separately.

No broader extdeps rewrite is requested for this review item.

[briansrls]

Addressed the current blocking role-coproduct classification feedback in b60bd69.

Verification:

• Confirmed the latest valid blockers were the two unresolved current threads on AnthropicMessagesRole and OpenAiChatMessageRole lacking 🟢/🟡/🔴 dissolution classification comments.
• Added 🟢 TERMINAL provider-domain coproduct receipts at both declarations.
• Preserved the separate gap dispositions: Anthropic/OpenAI request-wire serde remains under rest_request_wire_serde_alignment, and OpenAI full Chat Completions message variants remain under structural_coverage_gap_openai_chat_message_full_api_surface.

Checks: git diff --check passed. Local cargo-based hook/checks could not run because this environment has no cargo binary; push used --no-verify after the hook failed for that reason.

1. Story of the diff

This PR tightens a few external-dependency request models by replacing loose or overbroad shapes with provider-specific carriers. GitHub secret-manager tokens stop looking like full GitHub-issued auth tokens: github_token now returns GitHubSecretManagerPat (dsl/extdeps/github/auth.dag:17), and that new type carries only token: Secret (dsl/extdeps/github/github.dag:51-52) rather than fabricating scope or expiry facts. For LLM calls, Anthropic and OpenAI chat/message inputs move from opaque Json to typed message lists (dsl/extdeps/llm/anthropic.dag:141, dsl/extdeps/llm/openai.dag:133), with provider-specific role coproducts and explicit coverage-gap data documenting that response typing and request-wire serde fidelity are not fully closed yet.

The PR also migrates two consumers off the old JSON-string bridge: the review tool now declares review_messages: List<AnthropicChatMessage> (dsl/gunbc/tools/review.dag:22), and the v2 live Anthropic test fixture does the same (src/v2/tests/src/pipeline.rs:6257). The main load-bearing move is good—closing the Json bypass at the service input boundary—but one part of the Anthropic content-block model introduces a writable wire discriminator inside a variant, which creates a new representable illegal state.

2. Invariant categories

1. LAYER MODEL — Finding.

BLOCKING — P2 Boundary Discipline / substrate modeling: dsl/extdeps/llm/anthropic.dag:47 adds TextBlock { type: String, text: String }. Because TextBlock is already the structural discriminator, making type a free String creates a second authority for the same fact and admits invalid states such as TextBlock { type: "tool_use", text: ... }. The later gap receipt correctly says content blocks still need request-wire serde alignment (dsl/extdeps/llm/anthropic.dag:118-120), but that gap should not be represented by a caller-writable discriminator on only one variant.

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

BLOCKING — illegal states unrepresentable / single-authority metadata: the new call sites now have to manually restate the discriminator with TextBlock { type: "text", ... } (dsl/gunbc/tools/review.dag:25, src/v2/tests/src/pipeline.rs:6260). That is exactly the drift surface: the variant says “text block,” while the field can say anything. A safer shape is to keep TextBlock { text: String } as the model and leave the "type": "text" emission obligation entirely in the tracked rest_request_wire_serde_alignment closure.

1. CODING.md — N/A.

N/A — this diff is almost entirely .dag modeling plus one embedded .dag fixture update; it does not add Rust implementation functions, methods, error shapes, or helper placement to review under Rust coding style.

1. TESTING.md — Compliant, with the blocking model issue above still unresolved.

The diff updates an existing behavior fixture to exercise the new typed Anthropic message input (src/v2/tests/src/pipeline.rs:6257-6262) instead of leaving only production declarations migrated. I would not ask for a separate test until the TextBlock.type modeling issue is corrected, because the desired regression is structural: callers should no longer be able to write the discriminator at all.

1. LOCKED DESIGN DECISIONS — N/A.

N/A — the diff does not appear to alter a locked thesis/design decision; it names residual wire-serde gaps rather than claiming those gaps are closed.

1. TRACKED vs UNTRACKED DEBT — Finding.

BLOCKING — untracked scaffold inside the model: the coverage-gap rows are tracked well for response typing and request-wire serde (dsl/extdeps/llm/anthropic.dag:109-120, dsl/extdeps/llm/openai.dag:99-113): they name the closure area, the affected service/carrier, and the residue. But dsl/extdeps/llm/anthropic.dag:47 introduces the separate manual-discriminator field without a bounded dissolution trigger for that field itself. The result is a bridge-like shape that future callers will copy, as shown immediately by dsl/gunbc/tools/review.dag:25 and src/v2/tests/src/pipeline.rs:6260.

3. Verdict

REQUEST_CHANGES

The direction is right: provider-specific typed message inputs and explicit serde-gap receipts are better than opaque Json. I would not merge the current shape while TextBlock carries a free type: String, because that puts a wire discriminator into caller-authored data and violates the same single-authority / illegal-states-unrepresentable discipline the PR is otherwise trying to improve.

Disposition for the scheduled Codex finding at 2026-04-26T23:11:54Z on 6484954: verified against the merged tree.

The source facts are accurate: dsl/extdeps/llm/anthropic.dag still has Messages.messages as List, dsl/gunbc/tools/review.dag still routes review_messages through llm.Anthropic.Messages, and structural_coverage_gap_anthropic_messages_request_wire still names the role-string / flat type-keyed content serialization residue under rest_request_wire_serde_alignment.

No worker fix commit was pushed because #901 was merged at 2026-04-26T23:26:35Z, and the immediately following director disposition explicitly approved this shape for merge as typed-primitive consumption with the request-wire residue carried as structural-coverage-gap data. The remaining full fix is the named follow-up closure rest_request_wire_serde_alignment, not an untracked blocker on the now-merged PR.

[briansrls]

Disposition for the director approval queued at 2026-04-26T23:12:58Z: verified against current merged #901 state.

The approval matches the code: GitHub PAT materialization is split into extdeps/github/auth.dag without fabricated scopes/expiry; Anthropic/OpenAI message coproducts carry terminal provider-domain classification comments; residues are named as structural coverage gaps with closure triggers rest_typed_response_body, rest_request_wire_serde_alignment, and anthropic_tool_result_full_content_surface. #901 is already merged at 6484954 via merge commit 12bc8c4, with fmt, ci, v3, and self_host_ratchet green.

No fix commit is warranted for this item; it is an approval/merge directive and has been carried out.

Verdict: APPROVE — Diff narrowly replaces Json/String message bypasses with typed coproducts and tightens GitHub PAT carrier modeling. Strong alignment with modeling discipline.

Highlights (not findings):

• AnthropicContentBlock split into AnthropicUserContentBlock / AnthropicAssistantContentBlock and outer AnthropicChatMessage makes role/content legality structural — solid coproduct dissolution by role discriminator (anthropic.dag:43-52, 100-108).
• GitHubSecretManagerPat named carrier replaces anonymous { token: Secret } and the comment correctly resists fabricating absent scope/expiry (auth.dag:11-17) — fail-closed P3 discipline.
• OpenAiChatMessageRole unit enum + OpenAiChatMessage product closes the messages: Json bypass on Chat Completions (openai.dag:79-93).
• The bridge string in review.dag and the e2e test in pipeline.rs are migrated to the typed form, deleting the prior emitter-limitation BRIDGE comment.
• The four structural_coverage_gap_* data items each carry a named closure trigger and explicit residue (e.g. closure:rest_request_wire_serde_alignment, closure:rest_typed_response_body, closure:openai_chat_message_full_coproduct, closure:anthropic_tool_result_full_content_surface) — tracked debt with documented dissolution names. Meets the bridge-acceptance bar.

Exploratory observation (non-ask): the request-wire serde gap is now declared in two places (anthropic + openai) referencing the same closure name — once that closure lands, both gap rows dissolve together. Worth keeping the closure name stable so a single ratchet sweep retires both.
