Edge-Node Provider Execution

목적

Edge owns provider selection, queue admission, leases, and connection-generation fencing. Node owns local provider adapters and executes normalized runs or provider HTTP tunnels after a ready handshake.

The shared packages/go/execution package contains provider lifecycle, registry, execution events, failures, cancellation, usage, and optional tunnel/command primitives. It does not manage host programs or durable conversation state.

기능 목록

기능	설명
register/readiness	등록된 Node의 현재 connection이 readiness를 완료한 뒤에만 dispatch한다.
normalized execution	adapter + target으로 provider 실행을 선택하고 ordered RunEvent stream을 반환한다.
single-request coordinator	Immutable admission과 closed stage envelope을 service-owned state graph (accepted, planning, working, reviewing, repairing, internal_tool, finalizing, completed, failed, cancelled)로 처리한다. An internal tool result can resume only its saved stage. After a successful workspace open, every terminal path waits for one cleanup before the finalizing candidate can reach surface acknowledgement.
single-request S11 terminal policy	One validated, copy-safe terminal disposition is frozen across envelope/result/progress with kinds end_turn, length, error, and cancelled. Error classes are provider, validation, timeout, budget, repetition, malformed, context, internal_tool, and workspace_cleanup. Cleanup can replace a pending success/length before publication; no acknowledgement race can publish a second terminal.
single-request observation evidence	Stage-pure timing, tool/cleanup/total counts, cardinality-bounded labels, Node logs, and raw-free correlation are documented for the single-request path. iop_anthropic_single_request_ingress_total is strictly unlabeled. A separate edge_single_request_terminal_rejection event projects only the fixed terminal kind/error class and HTTP status, so malformed and validation remain distinguishable without raw model output. The provider-normalization layer accepts and discards bounded standard/provider Chat Completions bookkeeping (usage, service_tier, system_fingerprint, provider timings, choice logprobs, message annotations, null refusal) plus optional string message.reasoning_content before emitting the canonical private stage envelope; none enters stage results or artifacts, while a non-null refusal, non-string reasoning, and unknown envelope members fail closed. Gemini Plan/Review also admit only exact non-empty extra_content.google.thought_signature; terminal signatures are discarded and a Review tool-call signature is replayed only in the matching request-local Gemini continuation. Work, artifacts, results, and observations never retain it. The Claude qualification child disables SDK retry and session-title generation so only the actual task can consume ingress. Internal tool names, raw arguments, and private results are absent from public output and log projections. SDD S12 qualified the external Claude path on an approved IOP Node with ingress 0→1, Gemini → ornith-fast → Gemini stage order, one end_turn, the exact expected workspace result, timing, cleanup, and redacted evidence.
workspace admission	An opaque workspace_ref resolves only through the configured Node catalog. Edge freezes the exact configured owner, dispatch-ready connection generation, closed operation/command/environment-name capabilities, and effective limits before executor startup; unavailable, foreign, pending, malformed, and stale candidates fail closed without fallback or reselection.
workspace runtime wire	The dedicated WorkspaceOpen/Tool/Artifact/Cancel/Cleanup request-response families carry immutable coordinator identities and closed status/error codes. WorkspaceArtifact admits only enum-selected PLAN/REVIEW and READ/WRITE; it carries no relative path. Edge overwrites open capabilities with frozen request authority; Node copies only catalog-subset operations/command ids and equal-or-lower effective limits.
workspace tool executor	A validated `darwin
internal workspace tool loop	The service decodes only workspace_read, workspace_list, workspace_write, workspace_delete, and workspace_command, opens the admitted workspace once, dispatches one call at a time on the frozen generation, and delivers one deep-copied typed result to the emitting executor continuation. Unique request/stage/tool correlation, per-stage iteration/output/deadline limits, request wall-clock budget, and typed cancel fail closed without external continuation or reselection.
request-owned internal artifacts	SingleRequestController exposes closed plan/review read/write operations. Artifact calls and model workspace tools share one serialized lazy WorkspaceOpen, the exact admitted Node generation, the active stage deadline, the immutable output bound, in-flight work accounting, and one terminal cleanup. Node alone maps selectors to plan.md and review.md, and inventoried descriptor-relative reads fail closed on identity replacement.
Plan stage	The Plan runner validates the frozen effective template, emits the planning envelope, and sends the immutable task through the frozen Plan binding with reasoning_effort=high. Its first provider turn requires an admitted workspace_read or workspace_list; only a successful inspection result makes Plan completion eligible. The result stays in the request-local conversation and does not create another artifact. The runner then accepts the stage-owned strict JSON schema for one-line goal plus bounded one-line steps/verification arrays, validates the fields, adds Markdown bullets, renders the template deterministically inside Edge, and writes the resulting Markdown through SingleRequestArtifactPlan.
single-request provider normalization	Private Plan/Work/Review calls pass caller-neutral effort/tool/structured-output requirements to the selected protocol profile. The profile chooses Chat Completions or Responses and maps unsupported effort only downward. An explicit managed selector freezes the exact provider ID; default freezes no provider ID and accepts the provider pool's concrete choice while retaining exact model-group/profile/target/credential/tunnel fences. Chat and Responses provider results are both reduced to one canonical private Chat-shaped envelope before strict stage decoding. No new Edge-Node field is added: the selected operation continues through the existing provider tunnel operation field.
single-request effective templates	execution_presets[].single_request.templates optionally loads plan_file/review_file as bounded Markdown relative to the directory containing edge.yaml; absolute and empty paths, non-regular files, oversize (>8192 bytes), non-UTF-8, and invalid grammar fail closed at load, and each file falls back to its built-in default independently. Admission freezes the effective Plan/Review pair into the binding, so a later refresh reaches only newly admitted requests. Templates select internal stage input and internal artifact shape only; caller request/response schemas are unchanged.
Work and Review handoff	Work parses the stored PLAN with deterministic P1..Pn IDs, projects only admitted workspace tools, and writes exactly one validated REVIEW handoff containing item status, changes, verification, and deviations. Review rereads both artifacts before provider dispatch, has no memory work payload, performs any repair/re-verification in the request-local ledger, and writes no final REVIEW page.
request-owned cleanup	Node creates and inventories only .iop/job/<request_id> internal state, cancels and waits for all active command groups, validates the exact tree without following entries, and removes matching artifacts deepest-first with non-recursive descriptor operations. Symlinks, special files, foreign devices, identity replacements, and unowned entries fail closed. User results and sibling request state are preserved. Concurrent cleanup callers receive one bounded cached typed result.
provider raw tunnel	선택된 provider의 HTTP/SSE를 ProviderTunnelRequest/ProviderTunnelFrame으로 relay하며 순서와 단일 terminal outcome을 보장한다.
terminal ownership	Node normalized run과 raw tunnel은 caller cancel, configured hard deadline, provider terminal/error, transport disconnect만으로 끝난다. 무출력은 상태 전이나 retry input이 아니다.
provider admission	Provider-pool admission selects candidates by configured capacity, priority, health, and route capability. A provider terminal releases its lease exactly once; it does not create an automatic replay or alternate-provider selection.
OpenAI terminal consumption	Supported Chat/Responses normalized and tunnel paths project provider and transport terminal outcomes through their existing endpoint adapters. No watchdog-specific handoff reaches StreamGate.
tunnel-tolerant liveness	Edge와 Node는 30초 heartbeat interval과 45초 response wait를 공통으로 사용해 긴 prompt prefill이나 streaming backpressure 중의 정상 connection을 조기에 끊지 않는다.
reconnect/generation fencing	현재 connection이 종료되면 해당 generation만 fence하고 Node supervisor가 reconnect한다. Heartbeat wait를 넘긴 경우의 close reason은 heartbeat_timeout이다.
cancellation/command	run_id로 현재 run만 취소하며 command는 capabilities, transport status, Ollama API tunnel로 제한한다.
managed credential lease	Edge가 principal·route·slot·profile·target·Node·revision·generation을 binding한 sealed lease를 발급하고 Node가 capacity admission 후 provider 실행 직전에만 연다.

범위

• session_id는 event와 command result의 opaque correlation일 뿐이며 같은 값을 재사용해도 모든 run은 독립적이다.
• provider usage, capacity, queue pressure, lifecycle, reconnect, tool calling은 Edge-Node 실행 경로에서 계속 지원한다.
• single-request coordinator owns the service-level workspace admission described above as well as executor envelope privacy and the service-owned state graph. It exposes no workspace root, command executable/template/arguments, or environment values to the coordinator-facing binding.
• The request-local single-request quality gate classifies provider/tool timeouts, exhausted stage/request budgets, first proven repeated action/result no-progress, malformed calls/results, context/output limits, cancellation, internal-tool failures, and workspace cleanup into the closed terminal vocabulary. It retains only fixed hashes for repetition evidence and never retries, reselects, falls back, exposes a partial success, or starts a second request after classification.
• The service freezes the first public terminal candidate. Legacy successful results normalize to end_turn; output limits produce length; caller disconnect produces silent cancelled; validation/context become invalid_request_error; other errors become api_error. Buffered and SSE projectors share that policy, emit at most one terminal, and never expose private partial stage content for length. This completes deterministic S11 error-cancel evidence without changing the Edge-Node protobuf wire. S12 external Claude qualification on an approved IOP Node is complete.
• The request-local internal tool loop is implemented between the coordinator and the dedicated workspace wire. Strict decode and capability checks happen before wire effects; Node results are accepted only for the one pending call and return only bounded typed fields to the same optional executor continuation. Repeated or stale identities, malformed/denied calls, exhausted immutable budgets, and cancellation terminate internally without selecting another Node or involving the HTTP caller.
• Request-owned plan and review artifact access is implemented between the controller and the same dedicated workspace wire. Only SingleRequestArtifactPlan and SingleRequestArtifactReview are accepted. Artifact and model-tool callers share one serialized open attempt and the same opened cleanup gate; terminal and cancellation paths wait for in-flight artifact work before issuing exactly one cleanup. Edge bounds writes before dispatch and reads before acceptance, validates the echoed kind/operation and canonical terminal, and never reselects after a generation mismatch. Node maps the closed selectors to plan.md and review.md, validates the inventoried parent/file identity with descriptor-relative no-follow reads, and never grants the public workspace tool surface access to .iop.
• The private Plan stage is installed in the composite single-request executor at Edge input startup (apps/edge/internal/input/manager.go). Its provider codec accepts only frozen Plan options and selected dispatch facts, uses the admitted stage deadline and exact output limit, and projects provider failures to the closed stage terminal. Before structured completion, it exposes only frozen-authority workspace_read/workspace_list, forces the first turn to use one of them, validates the canonical call, and resumes planning through the shared correlated continuation bridge. A failed result does not unlock completion, and the admitted per-stage iteration limit bounds further inspection. No write/delete/command capability or separate analysis artifact exists in Plan. After successful inspection the stage owns a closed strict JSON response schema with exactly a string goal, a string-array steps, and a string-array verification; unknown, duplicate, missing, or mistyped fields fail malformed. It enforces a single-line goal, 2-6 non-empty one-line step items, and 1-3 non-empty one-line verification items. Edge, rather than the provider, adds Markdown bullet prefixes and newlines before substituting the values into the frozen effective Plan template. Required headings remain exact standalone lines, the documented placeholder inventory is closed, and unresolved delimiters are rejected. Provider output therefore cannot vary headings, bullet formatting, or static template text, and caller request fields cannot select, supply, or override the admitted template.
• The private Work stage is installed in the composite single-request executor at Edge input startup (apps/edge/internal/input/manager.go). It reads a non-empty bounded SingleRequestArtifactPlan, retains only request/stage/tool identifiers while waiting for the coordinator-owned continuation, and sends no reasoning_effort field in an initial or resumed provider request. Its response is rendered once as SingleRequestArtifactReview; write failure prevents Review, while partial report fields remain Reviewer-owned evidence.
• Review reads the stored non-empty bounded PLAN and REVIEW handoff before its provider call. Edge does not reparse the PLAN or pre-judge REVIEW semantic completeness. Review may inspect, repair, and re-verify with admitted tools, but it neither takes a memory worker result nor writes a final REVIEW artifact. A repair mutation requires later successful inspection evidence before PASS; caller output is byte-for-byte the reviewer strict output field and cleanup removes the temporary artifacts.
• The Node-private workspace request/result wire is implemented, including catalog delivery, parser registration, optional handler behavior, stable typed failures, generation-fenced dispatch, context-cancel propagation, and request cleanup. Before ready, a non-empty catalog requires a supported darwin|linux host and exact entry/host matching before any root open; unsupported and cross-platform catalogs fail closed while empty catalogs remain compatible. The Node installs the workspace handler before ready and cleans active requests before closing workspace authority ahead of session/store teardown. Request authority is immutable and request-local. File operations reserve .iop, reject symlink/mount/replaced-parent/special-file paths before effects, process bounded list batches with deterministic truncation, and use a same-parent structured write. Command execution resolves only admitted ids to fixed templates, enters the already-opened root descriptor through fchdir, provides only allowlisted environment entries, shares one output cap across drained stdout/stderr, and owns the complete process group through exit, timeout, context cancel, exact request/tool cancel, or request cleanup.
• managed mode는 등록과 dispatch 전에 CA로 검증된 Edge/Node workload identity를 요구한다.
• revoked, disabled, expired, stale, replayed, wrong-recipient, mismatched lease는 provider나 credential fallback 없이 fail closed한다.

IOP no longer provides persistent shell sessions, terminal emulation, process resume, local working-directory execution context, arbitrary host commands, or local quota/status probing.

Single-request lifecycle observation evidence links ingress=1, request-total=1, terminal=1, stage/tool/cleanup counts, and raw-free correlation for one real POST. iop_anthropic_single_request_ingress_total is strictly unlabeled (no request_id, stage_id, provider identity, content, or workspace reference). Internal tool names, raw arguments, and private results are absent from public output and log projections. Stage-pure timing, cardinality-bounded labels, and privacy semantics are documented here. SDD S12 external Claude qualification on an approved IOP Node confirms the same boundary with ingress 0→1, Gemini → ornith-fast → Gemini, one end_turn, the exact expected workspace result, timing, cleanup, and redacted evidence.

계약

• Edge-Node wire: agent-contract/inner/edge-node-runtime-wire.md
• provider execution primitives: agent-contract/inner/execution-runtime.md

Heartbeat interval/wait는 protobuf field가 아닌 양쪽 transport 구현의 connection profile이다. Provider execution request wire에는 watchdog timeout field가 없다.

설정/데이터/이벤트

• Edge와 Node의 현재 heartbeat interval은 30초, response wait는 45초다.
• 이 값은 runtime YAML model config나 max_tokens/context 설정이 아니라 transport 구현 상수다.
• 45초 동안 heartbeat response가 없으면 current connection을 heartbeat_timeout으로 닫고 provider resource를 offline 처리한 뒤 reconnect/queue 재평가를 수행한다.
• Provider catalog와 Edge-Node request wire에는 output-silence timeout이 없다. request hard timeout, queue timeout, provider HTTP timeout, transport heartbeat, client response-idle timeout은 각각 기존 owner가 처리한다.

한계와 주의사항

• 30/45초 transport heartbeat profile은 provider 응답 token 상한이나 model context window를 늘리지 않는다. 요청 중단 원인 판정 시 model 설정과 transport disconnect를 별도로 확인한다.
• 45초를 넘겨 실제 heartbeat response가 없는 connection은 기존과 같이 오프라인 처리하고 reconnect한다.
• Edge owns reception-generation and immutable-lease validation, provider-pool admission, and exactly-once release on terminal events.
• Output silence alone does not cancel a Node attempt, alter provider health, or select another provider. Explicit provider/transport terminal, caller cancellation, and the request hard deadline remain the terminal inputs.
• Workspace admission and the private wire both fence the exact ready connection generation. The wire never exposes workspace fields through provider RunRequest, NodeCommand, or public API output. The executor exposes no caller access to .iop; only request-owned internal runtime code can derive and inventory .iop/job/<request_id>. Structured write input is required for WRITE, while legacy content-only input remains rejected. COMMAND is non-interactive and has no shell, PTY, arbitrary argv, ambient environment, path-based cwd lookup, or persistent process ownership. Cleanup never rolls back or deletes user-requested workspace results.
• The composite single-request executor is installed at Edge input startup (apps/edge/internal/input/manager.go), wiring the active Plan -> Work -> Review stage pipeline for single-request execution. Private stage outcomes use the implemented closed S11 terminal policy and stop without retry/fallback or a second request. Deterministic local activation and terminal evidence are proven, and S12 (claude-smoke) qualifies the external Claude path on an approved IOP Node.
• Single-request observation evidence (ingress=1, request-total=1, terminal=1, stage/tool/cleanup counts, raw-free correlation) is documented and tested. iop_anthropic_single_request_ingress_total is strictly unlabeled. Internal tool names, raw arguments, and private results are absent from public output and log projections. SDD S12 confirms the external path with one ingress, the expected stage sequence, one terminal, exact output, timing, cleanup, and redacted evidence.

• 2026-08-15: Removed duplicate PLAN reparsing and REVIEW semantic pre-validation from Work/Review. Non-empty bounded artifacts proceed to Reviewer, which owns completeness checks and repair.
• 2026-08-14: Added bounded read/list-first workspace analysis inside Plan. Structured Plan completion now requires a successful inspection result in the same request-local conversation; Plan exposes no mutation tool and creates no additional analysis artifact (apps/edge/internal/openai/single_request_plan_stage.go).
• 2026-08-14: Restored artifact-only model handoff: deterministic PLAN P1..Pn IDs, one Work-authored validated REVIEW handoff, Review artifact reread with request-local repair/re-verification evidence, reviewer zero-write, and strict terminal output provenance.
• 2026-08-14: Moved private Plan/Work/Review provider calls onto the shared provider-normalization boundary. Stage requirements now select Chat or Responses without caller identity, unsupported effort maps only downward, and default-selector provider-pool choices no longer fail the post-dispatch validation that still fences profile, target, credential revision, model group, and tunnel path.
• 2026-08-14: Added common Chat result normalization for private stages so standard OpenAI bookkeeping fields are removed before strict decoding, matching the existing Responses-to-common conversion while preserving fail-closed refusal and unknown-field handling.
• 2026-08-12: Replaced nondeterministic free-form PlanMD generation with a stage-owned strict goal/steps/verification JSON response. Edge rejects unknown, duplicate, missing, mistyped, or out-of-bound fields and deterministically renders the already-frozen operator Plan template, preserving template customization and every caller-visible schema (apps/edge/internal/openai/single_request_plan_stage.go, packages/go/singlerequesttemplate/template.go).
• 2026-08-12: Replaced Markdown-bearing Plan string fields with bounded one-line string arrays and moved all bullet/newline rendering into Edge, removing the remaining provider-specific formatting dependency without changing the public Messages surface (apps/edge/internal/openai/single_request_plan_stage.go, packages/go/singlerequesttemplate/template.go).
• 2026-08-09: Replaced the Plan stage's structured JSON response contract with operator-configurable bounded Markdown templates. execution_presets[].single_request.templates resolves plan_file/review_file relative to the directory containing edge.yaml only, admission freezes the effective Plan/Review pair so a refresh reaches only newly admitted requests, the Plan stage prompts with and parses direct PlanMD against the frozen template, and the Review stage renders the internal REVIEW artifact from the frozen Review template while the caller-visible final response stays the model's decision.output (packages/go/singlerequesttemplate/template.go, packages/go/config/load.go, apps/edge/internal/openai/single_request_preset_binding.go, apps/edge/internal/openai/single_request_plan_stage.go, apps/edge/internal/openai/single_request_review_stage.go).
• 2026-08-09: Qualified S12 claude-smoke on an approved IOP Node. One supervised Claude task with SDK retry and session-title generation disabled produced ingress 0→1, Gemini → ornith-fast → Gemini, one end_turn, the exact 42-byte workspace result, stage/total timing, cleanup, and redacted evidence.
• 2026-08-08: Expanded workspace runtime admission to the closed darwin|linux implementation set with exact catalog/host matching before root open, preserved empty-catalog compatibility, and kept Windows/unknown hosts fail-closed.
• 2026-08-07: Implemented the S11 error-cancel boundary: one frozen service terminal disposition, request-local typed stage classification, fixed-hash repetition/no-progress detection, shared buffered/SSE Anthropic mapping, silent disconnect cancellation, private-partial suppression for max_tokens, and deterministic one-ingress/one-terminal/no-second-request evidence. The Edge-Node protobuf wire is unchanged and S12 remains pending.
• 2026-08-07: Installed the composite single-request executor at Edge input startup (apps/edge/internal/input/manager.go), activating the Plan -> Work -> Review stage pipeline. Production construction evidence is test-covered (apps/edge/internal/input/manager_test.go), while actual Claude/Mac external qualification remains explicitly deferred to S12 (claude-smoke).
• 2026-08-02: provider tunnel의 긴 prompt prefill과 streaming backpressure를 정상 traffic으로 허용하도록 Edge/Node heartbeat profile을 30초 interval/45초 wait로 복원한 현재 구현과 회귀 검증을 반영했다 (apps/edge/internal/transport/server.go, apps/node/internal/transport/client.go).
• 2026-08-15: Removed the provider output-silence timeout, Node cancellation/probe path, Edge health/replay handoff, and their observations. Existing explicit terminal owners and transport heartbeat remain separate.
• 2026-08-06: Added implemented Edge workspace admission for single-request execution: an opaque workspace_ref binds to one configured ready Node generation and a closed capability projection before executor startup. Admission rejects unavailable, foreign, pending, malformed, and stale candidates without fallback or reselection; Node-private wire, executor, filesystem path, and symlink enforcement remain deferred.
• 2026-08-06: Added the dedicated Edge-Node workspace wire. NodeConfigPayload now delivers the approved catalog; WorkspaceOpen/Tool/Cancel/Cleanup messages have closed typed outcomes, immutable coordinator identities, parser registration, and an optional Node handler. Edge dispatch is generation-fenced and context cancellation sends one typed cancel. Node filesystem and process execution are intentionally deferred.
• 2026-08-06: Completed the reviewed workspace file boundary repair. Edge now sends only frozen request authority, Node admits immutable catalog subsets/lower limits, and structured write reaches the file executor while legacy incomplete input remains rejected. The Go 1.24-compatible descriptor-relative no-follow write path validates before effects, bounded list processing retains fixed state, startup errors are path-free, and composition proves handler-before-ready plus workspace-before-session/store teardown. Command execution/cancellation and cleanup remain deferred.
• 2026-08-07: Implemented exact-template workspace COMMAND and typed cancellation. The Node uses an inherited-root fchdir/exec shim, minimal allowlisted environment, a shared draining stdout/stderr cap, and one process-group result owner across exit, timeout, context cancel, and exact request/tool cancel. Focused race tests cover non-zero exit, output overflow, descendant termination, cross-request isolation, and configured-root rename/replacement. Artifact cleanup remains deferred.
• 2026-08-07: Implemented the coordinator-owned internal workspace tool loop with closed strict schemas, one-time exact-generation open, ordered pending-call correlation, deep-copied raw-free continuation results, immutable iteration/output/deadline budgets, typed cancellation, and real one-POST multi-tool privacy evidence.
• 2026-08-07: Added request-owned workspace cleanup. Node inventories its exact internal request namespace and artifacts, cancels and waits for all request command groups, refuses unowned, symlink, special-file, identity, and filesystem-boundary mismatches, and removes only validated entries with no-follow non-recursive descriptor operations. Edge gates every opened-workspace terminal path on one typed cleanup before finalizing acknowledgement; cleanup failure converts pending success while preserving existing failure or cancellation categories.
• 2026-08-07: Added the closed request-owned PLAN/REVIEW artifact wire and controller lifecycle. Artifact calls share the model-tool lazy open and terminal cleanup gate, use the frozen Node generation and immutable bounds, and map only inside Node to inventoried plan.md/review.md files. Provider-specific stage drivers and actual Claude qualification remain deferred.
• 2026-08-08: Synchronized single-request lifecycle observation evidence: stage-pure timing (planning/working/reviewing/repairing/finalizing/completed/failed/cancelled), tool/cleanup/total counts, cardinality-bounded labels, Node logs, and raw-free correlation. External Claude/Mac timing evidence is explicitly deferred to claude-smoke (SDD S12). Deterministic coordinator/tool-loop tests cover the full single-request path without implying external qualification.
• 2026-08-08: Made the Gemini Plan output deterministic with a stage-owned structured response contract for the exact plan/verification object, retained the strict nonempty parser, and added a raw-free fixed terminal-rejection event that distinguishes malformed from binding validation without widening metric labels. The structured Plan response contract was superseded on 2026-08-09 by direct PlanMD template validation; the terminal-rejection event is unchanged.
• 2026-08-07: Added the private Plan stage and its fail-closed provider codec. The component uses only frozen Gemini dispatch/options, ordered bounded tunnel decoding, a bounded structured plan/verification response contract, and the closed SingleRequestArtifactPlan write. It is not installed; Work, Review/repair, activation, and S12 qualification remain deferred.
• 2026-08-07: Added the private ornith-fast Work stage. It reads PLAN through the closed artifact controller, emits only admitted workspace schemas, bridges exact request/stage/tool results without retaining payloads, and resumes the frozen route with bounded tool evidence. Work rejects reasoning_effort; Review/repair, composite installation, and S12 external qualification remain deferred.
