Raw Blame History

Current Roadmap

This is the live, short roadmap. Completed implementation plans and long slice history live under historical/. Current architecture references:

wf_api_architecture.md: workflow API, server, transport, and source package boundaries.
project_map.md: package map and entrypoints.
wf_cli.md: current CLI usage.

Current Product Shape

wf_cli
  -> local WorkflowApi or wf_transport_rpc_http.RpcWorkflowApiClient
  -> wf_server.WorkflowServer
  -> wf_api.WorkflowApi / admin surfaces
  -> wf_core / wf_artifacts / wf_sources_mcp

The durable product path is now wf-rpc-server plus neutral wf_config / wf_server composition. The old wf-mcp script remains a legacy/special-purpose MCP entrypoint and compatibility surface.

Completed: the async wf_client Python slice is verified against the real JSON-RPC ASGI application. It covers capability discovery, local graph authoring, remote validation, immutable artifact save, deployment selection, and durable run execution. Rich client objects have bounded, secret-safe repr() and _repr_html_() views that never perform remote I/O. Draft workspaces remain a separate server/admin surface and are not part of the client; server registration is explicit so the artifact -> deployment -> run path does not require draft storage.

Active Initiative: Workflow Console And Defense Demo

The next product-facing push is a local-first web console and defense demo that shows the lifecycle without forcing viewers to read raw JSON. It connects to a loopback wf-rpc-server through JSON-RPC, displays lifecycle records and traces, and runs a prepared lda.chat report workflow with a typed human approval interrupt.

Design contracts:

Implementation order:

Completed: self-describing interrupt request/resume schemas are carried through core execution, persisted run inspection, and resume validation.
Completed: deterministic examples/lda_report_workflow/ case study with local document, report, issue-board sources, and typed issue-review interrupt.
Completed: add a top-level web/ pnpm workspace with a React/Vite console, Hono local server, Effect JSON-RPC boundary, loopback connection flow, source inventory, protocol evidence, and production static serving. Design: workflow console foundation. Implementation: workflow console foundation plan.
Completed: add the generic console lifecycle explorer, exercised first through the artifact -> deployment -> run -> trace path, with interactive graph and raw RPC evidence. Design: workflow console lifecycle explorer. Implementation: workflow console lifecycle explorer plan. Draft workspace inspection reuses the same shell after the first vertical path. Slice 1 is complete: the routed console now provides real-server capability discovery and read-only draft workspace inspection with desktop and mobile acceptance coverage. Implementation: workflow console workspace foundation plan. Slice 2 is complete: the console now provides draft graph authoring through real mutation RPCs, schema-backed capability forms, route editing, validation diagnostics, operation evidence, and responsive graph-first mobile sheets. Design: draft authoring workbench. Implementation: draft authoring workbench plan. Slice 3 is complete: selected capability steps now expose Setup, Inputs, and Outputs editing with canonical whole-list replacement, malformed-row repair gating, truthful graph binding summaries, and mobile mounted-inspector state preservation. Design: selected-step dataflow. Implementation: selected-step dataflow plan. Planned authoring slices, in order:
- Slice 4 is complete: the Discover capability playground resolves self-contained local JSON Schema $ref / $defs references and exposes the existing workflow.capabilities.call operation through a generated input form with typed output, diagnostics, bounded/redacted evidence, and durable inline failure receipts. Direct capability calls are isolated smoke tests, not persisted workflow runs: they create no workflow state, routes, run records, or trace frames. Implementation: capability playground plan.
- The console review remediation gate is complete. The final verified dispositions are recorded in workflow console review remediation.
- Slice 5 is complete: composite input values extend canonical step-input bindings with a deliberate recursive literal/path expression model for arrays and objects. Start by exposing per-item Literal/Path controls in existing array editors, preserving order and schema-validating every element. Do not encode array assembly as synthetic targets such as items.0; retain the current simple path/literal bindings for ordinary fields. Design: composite input expressions. Implementation: composite input expressions plan.
- Slice 6 is complete: workflow contract graph adds selectable Input, State, Output, and Outcomes projections with focused forms for workflow contracts, explicit outcomes, entry point, and final workflow output bindings. One backend-owned, node-scoped authoring contract inventory supplies discoverable input, state, selected-step, and applicable runtime-context choices without high-level hardcoding or raw JSON hunting. The standalone capability playground remains literal-only until it has a real workflow scope. Design: workflow contract graph. Implementation: workflow contract graph plan.
- Slice 7: explicit End authoring and a typed Add step palette. End nodes are real stored steps; Input, State, Output, and Outcomes remain graph projections of workflow-level contracts rather than fake runtime steps.
- Slice 8: typed forms for interrupt, condition/choose/match, subgraph, and foreach/join steps, built on the focused draft operations already exposed by the workflow API.
- Slice 9: direct graph gestures. Typed handles and drag-to-connect lower through the same canonical route and binding mutations used by inspector forms; the graph never owns an independent editable document.
Completed: the web console can operate the prepared examples/lda_report_workflow/ deployment through run start, typed issue_review interrupt, resume, trace, and final output inspection.
Completed: lifecycle autoplay, typed approval, issue-board output, and replay. Design: demo autoplay and replay. Implementation: demo autoplay and replay plan.
Completed: React presentation mode foundation for the prepared workflow demo. Make the report workflow story primary, demote lifecycle evidence to supporting panels, and keep the layout usable on a 720p display. Decision: React presentation mode before Astro. Design: React presentation mode. Implementation: React presentation mode plan.
Completed: constrained demo agent that invokes one prepared recipe macro. This agent driver remains replay-only. A separate presentation runtime added live prepared-run activation in a later slice. Design: constrained demo agent. Implementation: constrained demo agent plan.
Completed: implement the original 12-scene defense storyboard as a no-scroll 720p compositor. Later slices expanded and then consolidated the current deck to 13 scenes. Content and evidence freeze before chat replacement, visual polish, or motion tuning. Design: defense presentation storyboard. Implementation: defense storyboard compositor plan.
Completed: make the workflow execution handoff the visual center of Scenes 9 and 10. The canonical replay now drives an interpreted operation surface, persistent execution graph, typed interrupt contract, and raw evidence drawer. Design: workflow takes the stage. Implementation: workflow takes the stage plan.
Completed: replace whole-stage theme switching with one scalable Editorial Canvas and prove the reusable recursive Interactive Figure through Scene 6. Design: defense presentation storyboard. Implementation: editorial canvas and Interactive Figure plan.
Completed: adapt the logical presentation canvas continuously from 4:3 to 16:9 and replace the resizing evidence drawer with a progress-row receipt and centered inspector. Design: adaptive presentation canvas and evidence inspector. Implementation: adaptive presentation canvas plan.
Completed: address the presentation CodeRabbit review pass covering reducer state semantics, agent approval cleanup, discussion modal accessibility, figure validation, keyboard roving focus, and stale demo agent spec wording. Implementation: presentation CodeRabbit fixes.
Completed: presentation chat uses source-owned AI Elements-style conversation, message, tool, and prompt-action primitives against existing AgentMessagePart / TimelineAgent contracts. Live AI SDK driver remains deferred; the current chat runs the deterministic timeline agent. Implementation: presentation AI chat surface.
Completed: schema approval surface for typed interrupt/resume decisions. Scene 10 and prepared-agent approval requests now render schema/payload approval UI instead of raw { "type": "object" } as the primary product proof. Implementation: schema approval surface.
Completed: presentation chat now drives the prepared workflow timeline. The chat run action, schema approval submit/revision, graph, evidence, and live/replay execution all share useDemoTimeline; AI SDK remains a later driver for the same seam. Implementation: presentation chat timeline bridge.
Completed: guided run beat gates connect Scene 10 schema approval, chat approval, graph focus, and evidence transitions into one deterministic presenter sequence. Implementation: guided run beat gates.
Completed: Scene 10 guided product moment primes replay state for direct hashes and stages approval, resume, output, and trace as one readable product flow. Design: Scene 10 guided product moment. Implementation: Scene 10 guided product moment plan.
Completed: presentation live/replay truth surface distinguishes reviewed replay evidence, live target readiness, live active run state, and replay fallback. Design: presentation live/replay truth. Implementation: presentation live/replay truth plan.
Completed: Scene 10 now presents factual run state: workflow input, interrupt payload, operator resume decision, output, and trace frame facts. The live workflow contract supports a same-run negative outcome; the current prepared revision recording uses a separate run identity and is documented as a factual follow-up. Implementation: Scene 10 factual run state.
Completed: presentation lifecycle story expansion splits the demo climax into prepared lifecycle, run start, typed human boundary, and resume/output/evidence scenes so Draft -> Artifact -> Deployment -> Run is visible before the run inspector details. Design: presentation lifecycle story expansion. Implementation: presentation lifecycle story expansion plan.
Completed: presentation demo proof composition makes scenes 9-12 factual and readable: the workflow graph reflects the prepared plan, approval shows input/interruption/decision only, and resume/output/trace expose scroll-contained proof panes. Implementation: presentation demo proof composition.
Future: presenter companion and defense evidence assets.
Add a static slide/appendix shell only after presentation mode is clear. Astro remains an option, not the default next surface.
Completed: presentation agent authoring story creates a canonical prepared authoring recording, Scene 7 as an authentic single-beat full-screen conversation, and Scene 8 as a 6-beat lifecycle with route-level coverage that never calls workflow authoring RPC operations during Scene 8 navigation. Implementation: presentation agent authoring story.
Completed: compress Scene 10 typed approval and Scene 11 resume/output/trace evidence into a decision-led, continuation-led presentation, and restore live prepared-run activation against the configured JSON-RPC target. Implementation plan: Scene 11-12 evidence and live activation.

Presentation visual audit, July 11:

Baseline-good: Scenes 3, 4, and 5 are good enough for now. Do not churn them unless a later rehearsal exposes a concrete problem.
Completed: Scene 1 introduces the agent-shaped product goal through Planner -> Tool surface -> Runner / platform, then identifies the last role as the implemented contribution. Scene 2 remains responsible for the automation problem. Scenes 2, 6, and 7 retain their concrete focal artifacts, and Scenes 7-9 share a prepared authoring/run spine. Implementation: presentation opening title.
Completed: Scenes 10-11 now use decision-led approval, continuation-led resume/output, and compact factual trace rows so approval, resume, output, and trace remain factual without competing panels or repeated low-signal values. A healthy prepared target remains live; failed health probes switch the presentation back to the offline recording.
Completed: Scenes 12 and 13 now close with a bounded evaluation board, contribution boundary/future-work map, and canonical defense-question index.

Completed: Presentation Recomposition And Authoring Story

Scenes 7 and 8 now present an external-agent request through a scripted presentation surface and factual prepared-authoring proof. Scene 7 is one local request-to-first-turn beat; its obsolete /handoff route fails closed. Scene 8 keeps a persistent prepared assistant pane beside six factual phase visuals in an adaptive approximately 26/74 split. The obsolete receipt/trace modal and lower chat dock were removed. Plans: presentation agent authoring story and Scene 9 assistant pane. The staged message-box completion is recorded in Scene 9 staged message box.

Recommended next visual slices:

Completed: Opening visuals rebuilt Scenes 1 and 2 around concrete diagrams for "AI-agent pursuit -> workflow substrate" and "direct actions are not reusable automation". Design: presentation opening visuals. Implementation: presentation opening visuals plan.
Completed: Presentation coherence pass added a 13-scene visual matrix, corrected Scene 2's direct-action metaphor into a chat/tool transcript, and marked demo beats with primary/support surface metadata so Scenes 7-11 can keep one dominant product proof at a time. Implementation: presentation coherence pass.
Completed: Scene 2 visual craft pass made the one-off side read as a chat/tool transcript and the reusable side read as a durable workflow blueprint, while preserving simple vocabulary and 720p readability. Implementation: Scene 2 tool-loop visual craft.
Completed: guided proof scene composition cleanup made approval, resume, output, and trace beats read as product evidence without chat competing for space. Implementation: guided proof scene composition cleanup.
Completed: Evidence and closing visuals make Scenes 12 and 13 readable as a defense artifact: bounded evaluation board, claim boundaries, future-work map, and canonical examiner-question index. Design: presentation evaluation and closing. Implementation: presentation evaluation and closing plan.
Completed: Presentation agent authoring story rebuilds Scenes 7 and 8 as a scripted surface representing an external-agent handoff and factual prepared-authoring proof. Implementation: presentation agent authoring story plan.
Completed: Scene 1 now introduces the agent-shaped product goal through Planner -> Tool surface -> Runner / platform, then identifies the last role as the implemented contribution. Scene 2 remains responsible for the automation problem. Implementation: presentation opening title.
Completed: harden the live/replay defense rehearsal path with visible live start readiness, submitted and revision-requested outcome evidence, deterministic replay fallback, current deep links, and reset instructions. The live contract is same-run; the prepared revision branch uses a separate recording and is disclosed in the rehearsal log. Implementation: defense presentation rehearsal.
Completed: Scenes 7-9 now use one dominant factual artifact per beat on the Editorial Canvas: authoring/repair evidence, a scripted light agent chat, and a light prepared lifecycle canvas with synchronized secondary chat. Implementation: Scenes 7-9 editorial focal proof.
Completed: revise the remaining visual outliers only when a screenshot identifies a concrete hierarchy, overflow, or factual-readability problem. Implementation: presentation follow-up visual/story pass.

Next: Scene 7–13 Defense Recomposition

The next presentation work is intentionally split into six implementation slices followed by a rehearsal gate. The broader story-flow review remains a separate activity after these surfaces are stable.

Completed: Scene 8 chat entry: replaced the standalone run button with a full-screen assistant-style chat entry. The local composer/send action reveals the first prepared authoring conversation without starting a workflow run. Implementation: Scene 8 chat entry.
Completed: Scene 9 staged message box: kept one message box visible across Discover, Draft, Validate, Artifact, and Deployment; Draft and Artifact Send advance the prepared lifecycle while preserving edited user turns, and Deployment Send records a truthful local run request without execution or RPC. Implementation: Scene 9 staged message box. The boundary is explicit: the compact demo footer may start the prepared run from Scenes 7–11, while Scenes 9–11 own run, decision, resume, output, and trace evidence.
Completed: Live/replay truth and run activation: the compact footer rail across Scenes 7–11 exposes the prepared-run action, retries the existing health probe, starts live execution explicitly, and keeps direct links and failed services on truthful replay evidence. Scene 9 remains the semantic start of execution evidence. Implementation: presentation live/replay activation.
Completed: Scene 11 compression: reduce the typed-human-boundary scene to two beats: interrupt context and approval decision. Cancellation remains a decision outcome rather than a near-duplicate presentation beat. Implementation plan: Scene 11 decision beat compression.
Completed: Scene 10 factual proof and graph composition: the factual graph, selected input files, and proof layout are now implemented. The completed plan is Scene 10 factual graph and proof layout. File-preview rendering remains explicitly deferred as a separate follow-up.
Completed: presentation demo-chrome ownership: Scenes 7–11 share one route-projected footer rail for run, replay fallback, retry, paused, and terminal states. Design: presentation demo-chrome ownership. Implementation: presentation demo-chrome ownership plan.
Completed: visual scale and color pass: removed unwanted blue from Scenes 2 and 13, shorten Scene 2's two-column composition, enlarge the focal diagrams in Scenes 7, 8, 12, and 13, separate Diagnose from Repair visuals, and improve Scene 1 title-box padding and contrast. Design: presentation visual scale and color pass. Implementation: presentation visual scale and color pass plan.
Completed: defense rehearsal gate: all 13 scenes have paired 1280x720 and 1024x768 replay captures, and the rehearsal matrix, log, and story audit are recorded. The live end-to-end path remains blocked, the prepared revision branch has a separate recorded run identity, and the full web test gate passes after route-contract stabilization. Historical implementation plan: defense rehearsal gate. Route matrix: presentation rehearsal matrix; Story-flow audit: presentation story audit; dated evidence: presentation rehearsal log.
Completed: factual input file browser: Scene 9 presents the run-selected documents as a read-only browser with selectable prepared-fixture Markdown excerpts and a separately labelled output destination. The preview states that it is not execution evidence; the UI does not claim per-file reads because the current trace recording does not expose them.
Completed: presentation follow-up visual/story pass: clarified Scene 1 and the lifecycle-to-authoring narrative, gave Scenes 7 and 8 a stronger dominant artifact, made the Scene 9 graph easier to present, and densified Evaluation and Conclusion beats without inventing evidence. The dated review records the remaining factual input-browser, live-E2E, and full screenshot-inspection follow-ups: presentation follow-up visual review. Implementation plan: presentation follow-up visual/story pass.
Completed: presenter speech and live documentation reconciliation. The typed catalog, live runbooks, README, and active contracts use the consolidated 13-scene story. The audience route passed the 1280x720, 1024x768, and 1920x1080 browser gate, including the six-step lifecycle, right-column discussion rail, and optional NodeUse deep link. Implementation: consolidated authoring story.

Presentation wishlist / defense readiness:

Completed: Simpler Speech

Completed: gave every beat one audience goal and one to three anchor terms, then simplified the timed presenter path through Scenes 1-8 to one suggested sentence per beat. Keep essential vocabulary such as Workflow API and lifecycle record names, while moving detailed qualification into optional notes or Q&A. The current catalog contains a 9:27 must-say path with a 500-700 word budget and a 10:42 complete-deck target. Implementation: defense speech simplification.

Completed: Factual Scene 8 Evidence

Scene 8 now presents six factual reviewed evidence variants. Diagnose records missing_outcome_edge at nodes[analyze] in revision 3; Repair records the exact wf draft set-route lda_report_workflow --revision 3 --step analyze --outcome ok --to __end__ command and a valid revision 4 result with zero diagnostics. Direct-hash route assertions cover the Diagnose and Repair beats. Implementation: Scene 8 product evidence.

Design: defense speech and Scene 8 product evidence.

Completed: Distance-Readable Scene 8 Diagrams

Each prepared lifecycle beat now gives its primary meaning to a large diagram: source discovery, one continuous Draft/Diagnose/Repair workflow graph, artifact freezing, and deployment binding. Exact reviewed commands, diagnostics, IDs, and counts remain available as compact secondary receipts. Dagre reserves graph ranks for route-state labels, while React Flow refits after scene-column resize. Implementation: authoring lifecycle diagram pass.

Completed: visual pass for Scenes 6, 7, and 10 fixed architecture figure scale, authoring-loop clarity, interrupt/evidence emphasis, and presenter-note treatment. Implementation: defense presentation visual pass.
Next presentation visual slices:
1. Completed: contrast and readability fix pass repaired dark-on-dark text in the Scene 7 authoring loop and the Scene 10 chat rail, and ignored local .visual-smoke/ screenshots. Implementation: presentation contrast readability.
2. Completed: surface theme normalization pass made light chat, discussion modals, and Q&A branches use the same editorial presentation surface. Implementation: presentation surface theme normalization.
3. Completed: scene composition pass expanded the positioning map, planner/runtime boundary, lifecycle rail, and Scene 10 demo graph/contract readability. Implementation: presentation scene composition.
4. Completed: alignment/layout polish fixed Scene 6 figure dimensions, settled React Flow fitting, Scene 3 chip/evidence collision, narrow chat rail behavior, and Scene 10 smoke route. Implementation: presentation alignment and layout polish.
5. Completed: demo climax craft pass made Scenes 9 and 10 read as one continuous product demonstration from agent handoff, to persisted run, to typed interrupt, to resume/output/evidence. Implementation: demo climax craft pass.
6. Completed: demo product proof layout pass hid chat during graph-heavy beats, kept workflow graph nodes in frame, added run-proof labels inside the graph, and cleared outcome panels below the receipt row. Implementation: demo product proof layout.
7. Completed: demo interrupt layout focus pass made approval/interrupt beats contract-first, reduced the graph to compact context where appropriate, and removed the remaining three-column crowding. Implementation: demo interrupt layout focus.
8. Completed: discussion craft pass replaced detached branch chips with a presenter question rail and rebuilt Q&A modals around answer, provenance, and presenter-note hierarchy. Implementation: presentation discussion craft.
9. Completed: discussion modal composition pass made Q&A and context-only routes stage-aware, with body/support/action regions instead of plain document cards. Implementation: presentation discussion modal composition.
10. Completed: Scene 10 guided product moment primes replay state for direct hashes and stages approval, resume, output, and trace as one readable product flow. Design: Scene 10 guided product moment. Implementation: Scene 10 guided product moment plan.

Completed: presentation demo proof composition makes scenes 9-12 factual and readable: the workflow graph reflects the prepared plan, approval shows input/interruption/decision only, and resume/output/trace expose scroll-contained proof panes. Implementation: presentation demo proof composition. 12. Completed: hardened the replay/live evidence handoff so the trace beat consistently renders canonical frames without stale or empty state. Implementation: presentation evidence handoff.
Completed: deck hierarchy pass gave Scenes 1, 2, 6, 7, 8-12, and 13-14 one focal artifact per beat, reused factual authoring/demo projections, kept one editorial canvas, and froze Scenes 3-5. Implementation: defense deck hierarchy pass.

Presenter runbook: defense presentation runbook covers exact URLs, keyboard controls, live RPC/demo fallback steps, story spine, timing, and short speaker notes for what to say if the live demo fails. defense speech and claim audit provides the current 9:27 speech plus navigation buffer, evidence qualifications, and prioritized 12-minute Q&A. Completed: defense story reweighting now provides a typed 39-beat presenter-note catalog, a 500-700-word must-say path, evidence warnings, and a 10:42 complete-deck timing contract. Completed: interactive graphs and Scenes 3-6 choreography adds restrained Scene 3-5 choreography, a semantic-zoom architecture map, the readable wf_core and NodeUse figures, and a factual prepared-run graph inspector. Completed: read-only presenter route provides a static speech, evidence, timing, fallback, and Q&A reader without RPC, replay, or audience-window synchronization.
Defense Q&A branch set: defense Q&A runbook collects answers for "Where is the AI agent?", evaluation validity, security boundaries, demo reliability, and other likely examiner questions. Completed projection into /present discussion branches: defense Q&A branch projection.
Chat surface replacement: make the prepared demo agent feel operable from a real chat surface, not from custom slide chrome. The chat should own the "run prepared agent" affordance, render tool calls/results with a standard modern AI-app vocabulary, and expose approval requests as normal chat events that can also drive presentation actions.
Completed: guided run beat gates connect Scene 10 schema approval, chat approval, graph focus, and evidence transitions into one deterministic presenter sequence. Implementation: guided run beat gates.
Completed: Scene 10 guided product moment removes delayed direct-link readiness and gives approval, resume, output, and trace one dominant proof surface each. Design: Scene 10 guided product moment. Implementation: Scene 10 guided product moment plan.
Completed: presentation lifecycle story expansion makes the demo climax less run-only by adding explicit prepared lifecycle scenes before the run, interrupt, output, and trace proof. Design: presentation lifecycle story expansion. Implementation: presentation lifecycle story expansion plan.
Evidence assets and rehearsal timing: prepare fallback screenshots/recordings, expected run states, and a timed walkthrough checklist for a 15-minute defense.
Completed: LAN presentation synchronization pairs /present and /presenter through an ephemeral bidirectional room with uniform code/QR/URL pairing, revision-ordered location updates, reconnect behavior, and explicit presenter termination. Public-internet TLS is not part of the first slice: LAN presentation synchronization design. Implementation: LAN presentation synchronization plan.

Boundaries: this is not a production admin panel, generic visual workflow editor, scheduler, external Google Drive/mail integration, or benchmark evidence for free-form autonomous planning.

Priority 1: Product Smoke And Status UX

The platform is usable enough to test as a product. Next work should focus on clear operator feedback before adding more architecture.

Completed: wf status is a compact read-only target/server status command, including durable run counts and the latest run summary when available.
Completed: a real CLI smoke pass against wf-rpc-server --config wf.config.json is captured in 2026-06-09 product smoke RPC CLI.
Completed: wf artifact inspect now accepts --version as an alias for the positional version argument.
Completed: wf artifact delete <artifact_id> <version> --confirm deletes unreferenced artifact versions and rejects versions still referenced by deployments. Implementation: wf artifact delete.
Completed: wf draft delete <workspace_id> --confirm exposes existing draft workspace deletion as a safe CLI command. Implementation: wf draft delete CLI/RPC.
Completed: bounded RPC CLI smoke runbook with cleanup commands: RPC CLI smoke runbook.
Completed: automated RPC CLI smoke example: RPC CLI smoke example.
Completed: cap call output is safer for humans through compact/text modes without changing default JSON semantics. Implementation: cap call output safety.
Completed: raw JSON/YAML workflow plans can be turned into artifacts through JSON-RPC and wf artifact create-from-plan, allowing agent/evidence harnesses to use the product-facing CLI path.
Completed: the opencode browser-click challenge harness is local-first via wf --config examples/browser_click_workflow/wf.config.json --local, with optional --start-server / --server-url modes for JSON-RPC-path trials.
Completed: focused draft edit helpers are exposed through RPC/CLI, and wf deploy create is accepted as an alias for wf deploy save. Docs now distinguish draft shape from raw plan shape for agent authoring.
Completed: capability-free draft lifecycle authoring now spans the Python API, JSON-RPC, remote client, and wf CLI. Callers can create an empty revisioned workspace, set its entry point, and replace whole workflow schemas or outcomes without RFC 6902 patches. Implementation: draft workspace lifecycle authoring.
Completed: semantic draft edits now gate workspace and capability preflight on the expected revision, so stale callers consistently receive revision_conflict while the patch path retains its mutation-time race guard. Implementation: draft semantic revision precedence.
Completed: focused draft bind and capability-step insertion now preserve nested node-local paths and project nested capability schemas through one shared bounded JSON Schema path module. CLI and agent guidance distinguish rooted bind endpoints from implied rootless map targets. Implementation: nested local draft bindings.
Completed: wf draft set-input and wf draft set-output now accept --merge, preserving existing bindings when agents split map edits across multiple revisions.
Completed: wf schema now lists workflow document/component models, emits compact JSON outlines for agent discovery, and emits valid self-contained JSON Schema with --verbose.
Completed: wf draft bind --from ... --to ... composes input/state/output schema projection with step binding merge, replacing the prior narrower output-to-state helper and reducing manual draft patch repairs in agent challenge runs.
Completed: draft CLI vocabulary now uses wf draft create --capability and the typed wf draft add <kind> command tree. All nine draft step kinds have dedicated commands; capability insertion retains schema projection, while interrupt and subgraph commands preserve their explicit boundary contracts. Generic insertion is exposed through Python and JSON-RPC with atomic incoming and outgoing route wiring. Implementation: generic draft step authoring.
Completed: wf draft branch and wf draft handle provide atomic route editing for existing draft steps without rewriting the full routes object.
Completed: wf draft compile returns the compiled raw plan plus required capabilities without mutating or saving the draft workspace.
Completed: draft validation now preserves structured core validation issues and adds exact wf draft bind repair hints for missing state fields.
Completed: wf explain now covers draft/workflow validation codes such as unknown_edge_destination, invalid_source_path, and patch_invalid. Implementation plan: draft explain diagnostics.
Completed: draft workspaces can persist invalid intermediate route states, allowing agents to add missing target steps before final validation/save. Implementation: invalid intermediate draft authoring.
Completed: draft workspaces expose focused remove commands for routes, steps, and step bindings so agents can recover from bad edits without raw JSON Patch. Implementation: draft remove commands.
Completed: wf draft set-workflow-output and full-stack API/RPC/CLI support for editing top-level workflow output bindings. The compatibility map adapter remains available for existing callers. Implementation: set-workflow-output API/RPC/CLI.
Completed: canonical workflow-output replacement now preserves ordered path/value bindings across Python, JSON-RPC, MCP, and CLI; nested input/state sources can project missing output schemas, while literals and context.* require declared targets. Empty replacement restores implicit same-name state fallback; compatibility --merge --map remains intentionally lossy. Implementation: atomic workflow output bindings.
Completed: compatibility map merges now reject canonical input/output bindings they cannot preserve, and local or remote CLI users can export an exact draft document and revision-check its import into an existing workspace. Structurally valid imports receive fresh semantic diagnostics and remain repairable when invalid. Implementation: safe compatibility merges and draft document transfer.
Completed: challenge-driven output UX polish makes set-workflow-output project missing top-level output schema fields from declared input.* and state.* sources, and challenge prompt templates now always include ux_issues_found: [] so debug-profile reports do not fail by omission.
Completed: wf draft bind now reuses existing workflow input/state schema fields when binding to step-local inputs, avoiding redundant-schema failures found by debug challenge runs. Implementation: idempotent draft bind inputs.
Keep status read-only; do not mutate registry, auth, config, or stores.

Priority 2: Durable Run/Resume Hardening

The v1 durable run and resume path exists, including persisted interrupted runs, bounded trace reads, dependency revalidation, and process-rebuild resume tests. Remaining hardening should focus on correctness under real server use.

Completed: same-process resume_run calls are serialized per run id. Implementation: resume run concurrency guard.
Completed: store-level locking/transaction expectations are documented for current file stores and future transactional stores: store transaction boundary.
Completed: paged wf run list exposes compact persisted stopped-run summaries without trace or checkpoint state. Implementation: run list API/RPC/CLI.
Preserve existing semantics: broken pinned dependencies return blocked readiness and diagnostics; ordinary live tool/source failures are failed runs, not implicit pauses.
Active specs:
- persisted run/resume contract
- durable workflow runs and resume

Priority 3: Source/Auth/Config Polish

Source registry, neutral MCP source config, role-specific stores, and local/dev auth admin are implemented. The next work is polish, not new broad surfaces.

Keep config bootstrap separate from mutable store-backed source registry state.
Keep auth payload values write-only; display summaries must show metadata and payload keys only.
Keep role-specific stores filesystem-only until a real SQL/secret-manager slice is planned.
New source families should follow the generic runtime source lifecycle rather than being forced through MCP ConnectionConfig: runtime source lifecycle.
Completed: static config kind: "python" sources can load trusted local NodeSpec registries and expose them through WorkflowServer. Implementation: static Python sources.
Completed: wf config validate preflights neutral workflow config files, including config-relative path resolution and trusted static Python source imports. MCP sources are shape-validated only; live upstream checks remain a server/status concern.
Completed: Python source operator docs and RPC integration coverage now prove ops.py source config, capability call, draft artifact creation, deployment, and workflow run. Runbook: Python source.
Completed: static source inventory providers now have an explicit WorkflowSourceProvider.load_sources() seam in wf_server, and Python source loading is behind PythonSourceProvider.
Completed: wf --local --config <workflow-config> now composes configured neutral server sources in-process instead of falling back to built-in static sources only. --local is process-local server composition, not local-only source transports or shared in-memory source sessions.
Completed: server startup policy moved to wf_server.cli; JSON-RPC HTTP remains in wf_transport_rpc_http: server CLI and transport boundary.
Next auth work: typed/discriminated auth records and source-owned auth binders (McpAuthBinder first) are now completed. Remaining: Google Drive MCP smoke through https://drivemcp.googleapis.com/mcp/v1 (manual/local-only, requires Google OAuth client credentials). OAuth refresh-token support and provider profiles are now implemented. Production secret manager integration and encrypted-at-rest file format remain deferred.
Completed source auth diagnostics: wf source diagnose <source_id> now reports transport/auth/catalog state without exposing secret payloads.
Completed source provider docs: docs/source_provider_guide.md now covers MCP HTTP, MCP stdio, Python sources, auth refs, OAuth refresh-token setup, diagnostics, and the Google Drive MCP caveat.
Completed platform source policy: documented fixed-id sources such as wf.std and wf.source are platform sources. They resolve by fixed source id, do not require self-bindings, and legacy explicit self-bindings such as wf.std=wf.std are accepted as no-op compatibility. Deployment validation still rejects non-self platform-source bindings as stale configuration. Other wf.* namespaces are described by their own source docs/policies.
Completed wf.source.read_resource: resource refs are inert pass-by-value data using logical_source; explicit platform helper nodes dereference them through runtime/platform context with bounded output.
Completed source inventory CLI polish: wf source resources and wf source prompts list source-owned resource/prompt names without fetching content.

Priority 4: MCP Package Split Finish Line

wf_sources_mcp now owns upstream MCP source implementation pieces: ids, registry DTOs, auth/catalog stores, discovery/catalog DTOs, SDK adapter/facade, runtime pool, schema helpers, tool events, wrappers, and adapter lookup.

Next split work should be selective:

Avoid new dependencies on the combined wf_mcp facade from durable server or transport packages.
Keep wf_mcp compatibility shims until callers are retired deliberately.
Move only pieces with clear package ownership. Do not move proxy/UI/App metadata support into workflow transports by accident.
MCP UI/App metadata remains source/proxy metadata only; do not advertise MCP Apps/widget support through durable workflow transports yet.

Priority 5: Runtime/Core Polish Later

Core runtime foundations for native subgraphs, concurrent foreach, lineage state, and durable stopped-run resume exist. Return here after product/server UX is stable.

Native subgraph polish: optional per-use-site child deployment overrides and clearer child trace inspection.
Concurrent foreach polish: reuse barrier/lineage machinery for future fork/gather.
Protocol-native progress: investigate MCP tasks/progress or WebSocket/SSE only after polling wf run watch proves insufficient.
OpenAPI sources: continue from openapi capability sources when a real non-MCP source is needed.

Recently Completed Platform Milestones

Completed: the composed Python OpenRPC contract now has a checked, transport-neutral manifest with a deterministic drift gate. Design: workflow contract manifest design. Artifact: workflow-api.manifest.json.
Completed: @lda/workflow-rpc generates all 70 wire operation names plus raw parameter/result types from the checked manifest. The generated artifact has its own deterministic drift check and proves the 16 authored Effect RPCs are a subset without broadening browser authorization.
Completed: a fail-closed representative JSON Schema-to-Effect translator handles constrained primitives, objects, arrays, anyOf, local references, and structurally guarded recursive synthetic schemas, with representative checked-manifest coverage. Unsupported union and conditional semantics remain typed translation failures. No runtime RPC or browser authorization behavior changed; runtime TypeScript parity is not complete.
Completed: a test-only parity harness translates all 32 payload/result sides of the 16 authored Effect RPCs. Health, sources, artifacts, deployments, and run-list fixtures agree; eight bidirectional result mismatches are pinned for the current representative run inspect/start/resume interrupt fixtures and the compact run-trace envelope/frame shape. No runtime decoder or browser authorization behavior changed.
Completed: all 16 current Effect RPCs now use generated runtime decoders from the checked manifest. Run inspect/start/resume use the complete persisted interrupt contract; run trace uses the full run envelope and canonical frame identifiers. The checked generator embeds only those operation schemas and reachable components, and a 64-container guard rejects adversarial request or response nesting before recursive JSON decoding. The authored browser allowlist remains unchanged.
Completed: duplicated Effect-client operation-name unions and guards now come from the authored operation metadata registry, with every name checked against the generated 70-operation inventory. The Hono browser proxy retains an independently authored, typed 16-operation allowlist so future client expansion does not broaden browser authorization implicitly.
WorkflowApiSurface is the protocol-neutral workflow operation contract.
wf_transport_rpc_http exposes local/static and MCP-backed WorkflowServer over JSON-RPC HTTP.
wf can target local or remote workflow APIs for capability discovery, draft authoring, artifact/deployment operations, run, inspect, bounded trace, resume, and cap call.
Desired source registry reads, mutations, and explicit apply/reload are exposed through JSON-RPC and CLI.
Neutral wf_config can express MCP sources, role-specific filesystem stores, and client/server target separation.
wf config migrate-mcp converts legacy broker configs to neutral workflow config without mutating the original.
McpRuntimePool is shared for stateful upstream MCP operations and has JSON-RPC E2E coverage proving session reuse across workflow runs.
wf run watch provides polling-based progress UX.
CLI expected errors are compact by default; wf --verbose ... preserves raw tracebacks for debugging.
Completed thesis case-study evidence bundle: examples/report_workflow/ provides a deterministic report workflow with Python source, fixture input, config, runbook, and tests.
Completed thesis system-design draft: docs/thesis/system-design-implementation.md now frames the platform as a formal system design/implementation report backed by docs/thesis/evidence-index.md and the report-workflow case study.
Completed supplemental browser-click workflow example with serial multi-node lifecycle evidence.
Completed: an opencode browser-click challenge harness captures external agent trials against the deterministic browser-click workflow example without changing product runtime code. The old staged-server modes were replaced by per-trial local configs in the generic V2 harness.
Completed: skills/, runbooks, and challenge prompt templates are treated as the agent instruction layer. Challenge reports now track when trials rely on product code, prior stores, adjacent attempts, or existing example solutions.
Completed: workflow/CLI agent instructions now form an explicit copyable bundle for controlled challenge profiles, use wf schema for public shape discovery, and avoid implementation/test-file guidance.
Completed: the generic agent challenge harness now supports data-driven manifests, layered prompts, explicit none|skills|all|debug profiles, one-hour hard ceilings, normalized OpenCode tool/token evidence, policy findings, and manual-audited reports. Two data-driven challenges exist: browser-click and report-workflow. The central run_trials.py runner accepts any challenge manifest. The debug profile is opt-in and captures evidence-backed UX issue reports separately from normal benchmark scoring.
Completed: report projections generate bounded Markdown and JSON reports for every V2 trial and regenerate both after audit without mutating raw evidence. Implementation: report projections.
Completed: challenge trial collection now supports bounded concurrency through run_trials.py --concurrency and a Python matrix runner, examples/agent_challenges/run_matrix.py. The PowerShell matrix helper now delegates to the Python runner.
Completed: shared agent challenge evaluation runbook documents trial execution, instruction profiles, manual audit, and the distinction between evaluation validity and policy coverage: agent challenge evaluation.
Completed: challenge matrix operations now have compact OpenCode thread titles, policy handling for canonical skill-document reads, and a central summarize_trials.py command for audited result tables.
Completed: agent challenge results now record OpenCode session metadata and resume commands, so incomplete provider runs can be continued without mutating original raw evidence.
Completed: canonical TOML path strings are the emitted workflow path form. Paths now serialize as "input.text", "state.echoed", and "message" (local). Structural {"root": "input", "parts": ["text"]} path objects remain accepted and are now advertised in generated schemas as an input form.
Completed: challenge-driven CLI UX fixes now provide exact available deployment binding suggestions, reject bare --bind-output state targets before RPC with compact guidance, and accept wf schema --full as an alias for --verbose.
Completed: wf draft bind with --from local.x --to output.y now lowers through state atomically (projecting into both state_schema and output_schema), and validation repair hints cover undeclared workflow input source paths. Implementation plan: bind repair hints.
Completed: capability-backed draft creation now auto-binds required inputs only; optional inputs are surfaced in wrapper-hint notes for explicit binding. Implementation plan: required-only wrapper inputs.
Completed: wf draft set-input rejects local.x targets before RPC and shows the equivalent bare-target mapping.
Completed: wf draft add capability --route errors include declared outcomes and direct add/remove repair guidance.
Completed: repeated idempotent wf draft bind input/state -> local behavior is covered by regression tests.
Completed: capability-aware canonical step-input replacement now supports structured assembly, literals, explicit null, fan-out, whole-payload projection, local/remote CLI modes, JSON-RPC, and MCP. Compatibility map merge remains available but intentionally lossy. Implementation plan: atomic step input bindings.
Completed: capability-aware canonical step-output replacement now preserves ordered repeated-source fan-out, projects missing state schemas atomically, and is available through Python, JSON-RPC, MCP, and local/remote CLI modes. Compatibility map merges remain available but inherently lossy. Implementation plan: atomic step output bindings.
Completed: capability-step creation now accepts metadata and ordered path/literal inputs, while focused presence-aware updates can clear selected metadata or atomically replace canonical inputs without changing use, routes, or outputs. Python, JSON-RPC, MCP, and local/remote CLI surfaces are aligned. Implementation plan: capability step updates.

Agent evaluation cohort status and policy:

Treat trials collected while product code, prompts, fixtures, harness logic, or workspace isolation were changing as formative evaluation. Preserve them as qualitative evidence linking observed agent failures to product/harness fixes, but do not pool their timing, token, or success metrics with a frozen cohort.
Completed: the primary longitudinal campaign now has N=3 per cell / 36 manually audited trials across two challenges, two models, and none|skills|all profiles. The explicit cohort manifest, aggregate Markdown, and SVG/PDF figures live in docs/thesis/.
The 36 trials span repository snapshots and a base-prompt change before the third wave. Treat the aggregate as longitudinal product/prompt engineering evidence, not as a frozen model comparison or causal profile experiment.
Keep product code, challenge prompts, supplied skill bundle, model variants, timeout, concurrency, fixtures, and enabled tool set fixed if a future controlled cohort is collected. Record the product baseline and rendered prompt hashes with every result.
Keep manual audit authoritative for final pass/fail/invalid interpretation. Automatic policy findings remain review inputs, not bespoke exceptions or final benchmark outcomes.

Planned challenge-driven UX follow-ups:

Composite binding and data shaping is now tracked as console authoring Slice 5 above. It covers mixed literal/path arrays as well as the underlying model needed later to map state fields into structured objects such as report.
