Ruben Fiszel 74f579e6d9 feat(pipeline): local development for data pipelines (CLI --local + pipeline dev preview) (#9840)
* feat(pipeline): local development for data pipelines (CLI --local + pipeline dev preview)

Add the local edit→preview→run loop for data pipelines (folders of `// pipeline`
scripts), the analog of `wmill dev` / `wmill app dev`, usable from a code editor
or an agentic loop — without deploying.

No backend changes: full body inference comes from the same wasm the frontend
uses (windmill-parser-wasm-asset), which returns assets + pipeline annotations in
one call; local runs reuse runScriptPreview with _wmill_skip_asset_dispatch.

- localGraph.ts: wasm-backed working-tree → asset-graph builder (the enabler)
- pipeline show/run --local; new pipeline docs (PIPELINE.md/AGENTS.md) subcommand
- pipeline dev watcher + /pipeline_dev page (PipelineDevView) rendering the same
  PipelineGraphEditor from the pushed local graph, run via preview
- cascadeRun.ts: reusable run primitives extracted from the route page
- regenerated CLI agent docs

See docs/pipeline-local-dev.md for the full design, test steps, and handoff TODOs.
The live `pipeline dev` browser preview is implemented but not yet stack-verified.

* fix(pipeline): connect managed-materialize producer in local dev graph

The CLI pinned windmill-parser-wasm-asset ^1.728.1, which predates managed-materialize support (added in 1.733.1); the frontend already pins 1.740.0. The CLI's wasm therefore never emitted `// materialize`, so the producer had no output edge and showed disconnected from its `// on` consumers. Bump the CLI to 1.740.0 (matching the frontend) and translate the parsed materialize target into the producer's write edge + materialize_target, mirroring frontend resolveGraph.ts.

* fix(pipeline): harden local-dev CLI (bare-.sql crash, defaultTs, docs clobber)

Review fixes, complementary to the dev-preview/materialize/multi-root work already
on the branch (none overlap those commits):

- localGraph: a bare `.sql` (no dialect) made inferContentTypeFromFilePath throw and
  abort the whole graph build — and wedge `pipeline dev` at startup. Skip the
  unclassifiable file instead. Also map `bunnative` → parse_assets_ts and add
  ruby/rlang/nu/powershell to the `#`-comment fallback.
- show/run/docs/dev: thread the resolved `wmill.yaml` defaultTs into the graph
  builder so `.ts` infers under the workspace's runtime (bun vs deno) instead of
  always bun — `opts.defaultTs` was always undefined (no such CLI flag).
- dev: wrap the startup graph build so a half-written file can't abort the watcher.
- docs: don't clobber a user-authored AGENTS.md/CLAUDE.md — only (over)write the
  pointer when absent or already a generated `@PIPELINE.md` pointer.

* fix(pipeline): bind dev WS to loopback + local-graph regression tests

- pipeline dev WS broadcast the folder's full script source (scripts[].content + temp_script_refs) unauthenticated on 0.0.0.0:3201 — bind 127.0.0.1 so it's not LAN-reachable (webview localhost + SSH/devbox port-forward still work).

- Add regression tests for the just-landed local-graph fixes: bare .sql is skipped (was a build/dev-startup crash), defaultTs threads into .ts runtime inference (bun vs deno), and #-comment languages (ruby) use the # annotation fallback.

* feat(pipeline): --frontend flag for pipeline dev page origin

wmill pipeline dev opens <remote>/pipeline_dev, but that route only exists in this build's frontend, so it 404s against a remote whose deployed frontend predates it. --frontend <origin> points the page at a locally-run frontend (REMOTE=<remote> npm run dev) while the API/token still target the remote — enabling the live preview against a real backend before the PR is deployed. No behavior change when omitted. Regenerated CLI agent docs.

* fix(pipeline): WS session token + details-pane live-reload refresh

Addresses CI review (Codex/Pi/Claude):

- dev WS: a browser tab could open ws://localhost:<port>/ws and receive the folder's full source (browsers don't enforce same-origin on WS, loopback bind alone doesn't help). Gate the upgrade on an unguessable per-session token carried in the dev-page URL (verifyClient → 401 without it). Verified: no-token/bad-token connections get 401 with no bundle.

- details pane: scriptRes keyed on [workspace, selection, draftScript] didn't re-run on a pipeline dev live-reload (same selection), so the open pane showed stale source. Thread a localScriptsVersion (the pushed bundle) into the key. Verified: editing a selected node's file updates the pane source without reselect.

- docs/pipeline-local-dev.md: refresh the stale 'not yet exercised' status + done TODOs.

* fix(pipeline): emit volume: annotation assets in local dev graph

Addresses CI review (Codex P1 / Pi P1): the wasm body parser doesn't surface `// volume: <name>` annotations — the frontend (infer.ts:parseVolumeAnnotations) and backend (asset_inference.rs) parse them separately and merge as rw volume assets. localGraph didn't, so a `# volume: cache` producer had no write edge and showed disconnected from its `// on volume://cache` consumer (and pipeline run --local wouldn't schedule downstream). Mirror the leading-comment-block scan (SQL excluded, matching both reference parsers) and merge into inferScriptAssets. Regression test added; verified producer -> volume://cache -> consumer connects.

Also (Codex P2): docs/pipeline-local-dev.md manual browser URL omitted the new ws_token param — without it the WS upgrade is rejected and the page sits disconnected. Doc now says to copy the URL the CLI prints (carries wm_token + ws_token) and recommends --frontend.

* fix(pipeline): runAll excludes event roots + review polish

Addresses CI review (Codex P1, Claude P2/P3):

- pipeline run runAll: derive the whole-pipeline selection from validStarts + descendants instead of all runnables, so an unqualified 'pipeline run <folder>' no longer fires event-trigger roots (kafka/mqtt/…) with empty args/side effects. Verified: a kafka root is excluded from the plan.

- cascadeRun.ts runBoundedCascade: use buildLineageDownstreamMap (read-aware) so a pure-reader runs after its producer, and return cyclic — parity with the route page's bounded run (the file is meant to be THE shared correct primitive).

- PipelineGraphEditor: storedRightPaneSize starts at 0 so the orientation-aware default (55% stacked / 40% side-by-side) actually applies on first open.

- localGraph fallbackParse (go/bash): scan only the leading comment header (no body-comment phantom triggers) and strip key=value options from the asset URI; regression test added.

- docs: reject '..' in the folder arg (it writes files under f/<folder>).

* fix(pipeline): route local previews to the // tag worker

Addresses CI review P1: the local graph/bundle dropped the parsed `// tag`, so a node annotated `// tag gpu` ran on the default worker in both `pipeline run --local` and `/pipeline_dev`, while the deployed pipeline routes it to that worker tag. Carry the tag through LocalScript / the pushed bundle / LocalScriptContent and pass it to runScriptPreview at all three launch sites. Verified: a duckdb node tagged `bash` produces a job tagged `bash`; regression test added.

* fix(pipeline): add asset partitions/schemas routes to OpenAPI, use generated client

The ducklake asset panels (PartitionStatusGrid, SchemaHistoryPanel) hit /assets/partitions and /assets/asset_schemas via raw fetch with cookie-only auth, because those backend routes were never added to openapi.yaml so the generated client had no methods for them. On /pipeline_dev (token-via-URL, no session cookie) the raw fetches 401'd. Add both GET routes + MaterializedPartition/AssetSchemaVersion schemas to openapi.yaml and call them through AssetService, which injects the bearer token, types, and cancellation automatically. Verified: Partitions + Schema tabs load in /pipeline_dev. (backfill stays a raw fetch — it's an EE-only route not in the OSS spec — with the token added inline.)

* chore(cli): regenerate bun.lock for windmill-parser-wasm-asset

package.json / package-lock.json carry windmill-parser-wasm-asset@1.740.0 but the tracked bun.lock (the CLI installs/builds/tests via bun) was stale, so fresh bun installs would resolve a different graph than the committed lock. Regenerated.

* fix(pipeline): show asset producer + its runs in the dev-preview panel

Selecting a ducklake/asset node in /pipeline_dev showed 'No producer for this asset' because selectionProducers wasn't passed (it's derived from the deployed graph on the route page, absent here). Compute it from the local graph's w/rw write-edges (incl. the // materialize target) and pass it through, mirroring the route page — so the panel shows the producing script and its (preview) runs, including data-test failures.

* fix(pipeline): carry annotation metadata onto local-graph runnables

The local graph emitted only path/usage_kind/in_pipeline/materialize_target per runnable, so /pipeline_dev and pipeline show --local weren't the same surface as the deployed graph for annotated scripts — missing the badges/lineage the shared canvas renders. Map the wasm-parsed partition_kind, freshness, tag, retry, data_tests, column_lineage, and materialize_strategy (derived append/merge/replace) onto each runnable, mirroring the deployed AssetGraphRunnableNode.

* fix(pipeline): exclude event handlers that are lineage descendants from runAll

The runAll guarantee ('never fires an event handler with empty args') only held for event ROOTS — validStarts excludes them, but runAll then unions in descendants(dag, start), so a kafka/mqtt/... handler that also reads an upstream pipeline asset (a lineage descendant of a valid start) still landed in the plan. Add eventTriggerScripts() and subtract it from the selection after the descendant union. +unit test.

Also: docs/pipeline-local-dev.md recipe used 'pipeline docs demo_pipeline' without --local (default queries the deployed graph → hits the empty hint); add --local.

* fix(pipeline): whole-pipeline run cuts at event handlers (drop their downstream too)

The prior runAll fix subtracted event handlers from the selection but left their downstream: for manual_root → asset_x → kafka_handler → asset_y → consumer, deleting only kafka_handler left consumer selected, and topoOrder then ran it as a root with missing/stale event-derived inputs. Replace the descendant-union+delete with reachableCutting(dag, validStarts, eventHandlers): traverse from valid starts but treat event handlers as cut points, so a node reachable ONLY through an event handler is dropped while one reachable via a non-event path stays. +unit test.

* fix(pipeline): recover // tag in the go/bash annotation fallback

The wasm path carries out.tag, but the go/bash fallback (and the wasm-error degradation path) only recovered pipeline + on, so a // tag gpu on a bash/go node — or a temporarily-unparseable ts/py/sql node — silently routed the local preview to the default worker while the deployed pipeline routes to the tag. Scan for // tag in fallbackParse too. +test.

* refactor(pipeline): extract shared assetProducers helper

The 'who writes this asset' write-edge derivation was copied verbatim in PipelineDevView and the pipeline route page — two copies that would drift. Extract assetProducers(graph, selection) into graphTraversal.ts and use it from both, keeping the dev view and route page in lockstep.

* fix(pipeline): cut non-autorun triggers on all run paths; multi-binding --upload

Address CI review: apply the data_upload/webhook/event barrier cut to the
single-root and bounded (--from/--to) paths, not just whole-pipeline; accumulate
repeatable --upload bindings per script (were overwritten); scope dev upload keys
by script+param to avoid basename clobbering; drop <script> from help text.

* fix(pipeline): reseed dev run form when a local edit changes the script's args

The read-only pane is keyed on script.path only, so in /pipeline_dev the selected
node re-resolves on every WS bundle without remounting; PipelineScriptView cloned
script.schema once, so adding/removing args left the run form on a stale schema
(could run with missing inputs). Extract PipelineRunForm (owns the SchemaForm
clone) and key it on the serialized schema: a real arg change reseeds the form,
an unchanged re-resolve keeps in-progress input.

* fix(pipeline): don't cut a scheduled/manual root that also has a non-autorun trigger

Address Codex P1: the barrier set subtracted only --upload-bound scripts, so a
script with both `// on schedule` and `// on data_upload` resolved as the start
yet was also a barrier — reachableCutting skipped it, giving an empty run plan.
Subtract all valid starts (schedule/manual roots + bound handlers) from barriers:
a legitimately-scheduled root runs on its schedule path even if it also carries a
caller-input trigger; pure input-only roots stay cut. Adds a regression test.

* fix(pipeline): deployed non-autorun enrichment, s3:// storage, --to cut accounting, tag regex

Address CI review (Codex P1/P1/P2, Pi P2):
- Deployed `pipeline run` recovers marker-only data_upload/webhook/email triggers
  from script bodies (like the `show` path) so input-only entrypoints are cut
  instead of auto-run empty on the deployed graph.
- `--upload s3://<storage>/<key>` keeps the named storage (authority) instead of
  folding it into the key, matching the S3Object round-trip convention.
- Bounded `--to` targets cut by a barrier are reported in droppedEnds (+warning),
  not reachableEnds.
- fallbackParse `// tag` matches a single token (\S+), rejecting multi-word prose.

* fix(pipeline): header-only deployed marker scan, fail-closed enrichment, default-storage s3 keys

Address CI review (Codex P2, cubic P1/P1/P2):
- Deployed marker recovery scans the LEADING comment header only (shared
  recoverHeaderMarkers helper, reused by the show enrichment too) so a body
  comment `// on data_upload` can't inject a phantom trigger and over-cut.
- Deployed run enrichment fails CLOSED: a script-body fetch error aborts the run
  instead of silently letting an input-only entrypoint run with empty args.
- Revert `--upload s3://` to default-storage whole-path keys (matching pipeline
  `s3://` asset-URI semantics); named-storage authority-splitting broke nested
  default keys like `s3://raw/2026/events.csv`.

* fix(pipeline): reject trailing content on fallback native markers; trim s3:/// key

Address CI review (Codex P2, cubic P3):
- fallbackParse now requires a native marker (`// on data_upload`) to stand alone;
  a line with trailing content (`// on data_upload f/foo`, `# on kafka topic`) is
  rejected, matching the canonical parser and keeping local/deployed parity.
- s3UriKey trims a leading slash so the canonical empty-authority default form
  `s3:///key` doesn't leak a leading slash into the object key.

* fix(pipeline): persist dev WS token per-port so reconnect survives a CLI restart

Address Codex P2: the /pipeline_dev auto-reconnect reuses the ws_token from the
page URL, but `pipeline dev` minted a fresh random token each start, so a restart
on the same port left the open page rejected by verifyClient forever. Persist the
token per-port under the user-private config dir (0600) and reuse it on restart,
so an already-open page reconnects — matching the reconnect behavior's intent.

* fix(pipeline): scope persisted dev WS token by workspace+folder+port

Address cubic P2: keying the persisted token by port alone let a stale browser
tab from a previous folder's session on the same port reconnect and receive a
different folder's source. Scope the token file by workspace+folder+port so a
same-session restart still reconnects, but a different folder on the same port
gets a distinct token that rejects stale cross-folder tabs.

* fix(pipeline): caller args can't override skip-dispatch guard; hash the dev token key

Address CI review (Codex P1, cubic P2):
- makeLaunch / CLI run build args with `_wmill_skip_asset_dispatch` LAST (and drop
  any caller-supplied copy) so a run-form/`--upload` arg can't re-enable backend
  asset dispatch while the client orchestrates the cascade (double-run / running
  deployed subscribers from a local preview). Adds a cascadeRun guard test.
- Dev WS token file key is a sha256 of NUL-delimited workspace+folder+port, so
  different folders (`a/b` vs `a_b`) can't collide onto the same token file.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(pipeline): canonical s3://storage/key --upload parsing; scope dev token by remote+root

Address Codex P1/P1:
- Restore canonical S3Object URI parsing for `--upload` s3 sources, matching the
  frontend's `parseS3Object` (`s3://<storage>/<key>`, empty authority ⇒ default,
  `s3:///key`/`s3:///nested/key` for the default store). `s3://secondary/k.csv` →
  `{ s3: "k.csv", storage: "secondary" }` so a named-storage object is read from
  the right store. (This is the canonical convention; the default-storage nested
  key is served by the `s3:///` form.)
- Scope the persisted dev WS token by remote+workspace+root+folder+port (was
  workspace+folder+port), so two profiles on different remotes (or local checkouts)
  with the same workspace/folder/port don't share a token — a stale tab can't
  reconnect across a workspace/remote boundary.
