test(ui): add YAML fixtures for the document model tests - #3385
Stacked PR 5/31. This PR depends on PR 4. I cannot push branches to this repository, so the base is main and the diff below also contains the changes of PRs 1 to 4. To review only this PR, use the diff of this PR alone or the same PR on my fork, stacked on the previous one. Please merge in order.
Part of a stack of 31 pull requests that depend on each other. They must be reviewed and merged in order.
Stack 5/31. Base branch: stack/04-g4. Review and merge in order; this PR builds on the previous one. Size: 43 files changed, 783 insertions(+). Checked: Typecheck (tsc) of the whole UI and the unit tests of this PR (Vitest), on top of the previous PR.
Summary
This PR adds 43 YAML fixture files under ui/src/features/visual-editor/doc/__tests__/fixtures/. It adds no code and changes no existing file.
Why
The tests of the YAML document model need real workflow files with odd forms. They are kept apart so that the code PRs stay small. The fixtures are read by the document model tests that start in PR 11; the model code itself comes in PR 10.

Walkthrough
The pull request adds YAML fixtures for visual-editor documentation tests. The fixtures cover YAML syntax and document structure, workflow execution and configuration, and browser, agent, ACP, embedded-executor, and spreadsheet examples.
Changes: Visual Editor YAML Fixtures
Layer / File(s)
Summary
YAML syntax and document structure ui/src/features/visual-editor/doc/__tests__/fixtures/{anchors-aliases,block-scalars,comments-everywhere,flow-collections,long-lines,invalid-yaml,map-steps-forbidden,map-steps,multidoc-comments-markers,multidoc-empty-between,multidoc-unnamed-later,nested-array-run,nested-parallel-groups,odd-indentation,quoted-keys-and-values,shorthand-steps,unicode-comments}.yaml
Fixtures demonstrate scalar and collection forms, comments, quoting, indentation, shorthand steps, and multi-document streams.
Workflow execution and configuration ui/src/features/visual-editor/doc/__tests__/fixtures/{build-comments,chain-router,config-cli,demo-graph-etl,embedded-local,foreach-string-items,handler-env,handlers-chain,folded-line-break,multidoc-subdag,run-context,scheduler-cron,router-numeric-band,router-regex-keys,spec-outputs-heredoc,spec-subdag-parallel}.yaml
Browser, agent, and data integration examples ui/src/features/visual-editor/doc/__tests__/fixtures/{browser-flow-maps,demo-agent-release,embedded-custom-executor,flow-maps-unicode,harness-acp,spec-harness-comments,spec-xlsx-convert,xlsx-japanese}.yaml
Fixtures configure browser actions, agent and ACP harnesses, an embedded executor, XLSX conversion, and Japanese spreadsheet extraction.
The fixtures are suitable for document-model testing, but running the browser fixture with untrusted data is unsafe, and repeating the spreadsheet workflow can fail. Neither fixture has an identified current execution consumer.

Review comments at @internal/runtime/runner.go:
- Around line 455-458: Reorder the completion handling around `finishNode` so
`finishNode` and `clampDependentStarts` complete, and `wg.Done()` is called,
before notifying the runner through `doneCh`. Account for Go’s last-in-first-out
defer execution so dependents and final status processing cannot proceed before
timestamp clamping.
- Around line 954-956: Update the dependent-clamping loop around
plan.Dependents(node.id) so ClampStartedAt applies only to dependents that start
in the current run. Exclude skipped or reused dependents carried from a source
run, preserving their historical StartedAt and FinishedAt timestamps.
Review comments at @internal/samples/dir.go:
- Around line 12-22: Update dirFor to prevent distinct step names from sharing a
store directory: when sanitization changes stepName, append a short hash derived
from the original name to the sanitized directory name. Preserve the existing
name for inputs that require no sanitization, and update TestSamplesStoreDir to
expect the hashed name for sanitized inputs.
Review comments at @internal/samples/events.go:
- Around line 133-138: Update finish to include the tracker’s running failure
count in the stopped event when an outage is active, and update loadTracker to
restore the count from the newest EventStopped or EventFailed carrying one,
preserving the larger count when restoring the outage tracker.
Review comments at @internal/service/frontend/api/v1/dags.go:
- Around line 351-362: Make the expectedSha256 comparison and spec write in the
DAG update handler atomic by moving the comparison into dagRepository.UpdateSpec
as a compare-and-swap operation. On a hash mismatch, leave the spec unchanged
and preserve the handler’s 409 conflict response; ensure the repository
operation is safe across frontend instances.
Review comments at @specs/013-step-run.md:
- Line 327: Update the `--outputs-from` description to specify that it carries
the work directory and outputs only from skipped steps that a selected step
depends on. Align the wording with the narrower rule implemented by
`carryingSteps` and keep the CLI help and reference documentation consistent.

Make the build output portable. date +%s%N fails on macOS.
BSD date on macOS does not support %N. It prints a literal N. Two runs that start in the same second then produce the same tag. require.NotEqual(t, firstTag, secondTag) at Line 61 fails on that platform.
Use a value that differs per run without %N. The shell PID differs for each run.
IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Assert the exact error text. "run" accepts almost any 400 body.
The body of almost every 400 response for this request contains the substring run (for example outputsFromRuns). This assertion passes even if the server rejects the ID for the wrong reason. The other cases assert the full message.

Relax the wall-clock bound on the samples request.
assert.Less(t, elapsed, 500*time.Millisecond) measures one HTTP round trip on a loaded CI host. The test reads three years of tiers through the full server stack. A slow or shared runner can exceed 500 ms with no regression, so the check is likely to fail intermittently. The unit test TestSamplesTiers already uses a 2 s bound for the reader alone. Use a similar margin here, or keep the bound only as a benchmark.

IsActive() excludes NotStarted, so an old NotStarted ephemeral run can pass the guard and be removed after its CreatedAt exceeds the TTL. Queued and Waiting are already protected. StatusBuilder.Create accepts NotStarted and assigns CreatedAt, so this path is feasible.

A negative limit reaches the file store and causes listRecentDAGRuns to slice with a negative bound. The same value also reaches the ephemeral store and merge helper.
The repository does not define a default of 10 for recent statuses. Reject or otherwise handle negative limits before delegating to the stores. Do not add the proposed limit = 10 default without an applicable contract.

Preserve timestamps on skipped, reused nodes.
When a selected run executes a and carries a skipped dependent b from a source run, exclude b from this clamp. ClampStartedAt can replace b’s historical StartedAt and FinishedAt with a’s finish time, although b did not execute in the selected run. Clamp only dependents that start in the current run.

Make the store directory unique for each step name.
dirFor maps every character outside [A-Za-z0-9_-] to _. Different step names can therefore get the same store directory:
my beat and my_beat both map to my_beat.
Non-ASCII names of the same length collide. For example, 日本 and 中国 both map to __. The repository fixtures include Japanese step names.
If two continuous steps in one run collide, two recorders on separate goroutines write the same raw/, minute/, and events.jsonl files. Each recorder has its own store instance. The tiers then mix samples from both steps. putFile rewrites can drop records that the other recorder appended. The event tracker also mixes the outages of the two steps. The API reader uses the same Dir function, so each step's charts show the combined data.
Add a short hash of the original name when sanitization changes the name. TestSamplesStoreDir expects my_beat, so update that test too. This is a new store, so no existing layout needs migration.

Keep the outage failure count across a restart.
loadTracker restores failed from newestFailed.FailedCount. A failed event is written only when the outage starts and then once each repeatFailedAfter (1 h). Failures after the newest failed event are not in any event. If the recorder stops during an outage, those failures are lost. The recovered event after the restart then reports a FailedCount that is too low.
Example: one failed event with count 1 is written, 30 more samples fail, and the recorder restarts. After 2 more failures, the recovered event reports 3 instead of 33. TestOutageAcrossRestart checks only Outage, so it does not catch this.
To fix this, store the running count in the stopped event when the tracker is in an outage. Then restore the count from the newest event that carries one. One side effect: toStepEvents sets failedCount for any event kind with FailedCount > 0, so the API will also show it on stopped events.

Make the expectedSha256 check and the write one atomic step.
The handler reads the current spec and compares its hash at lines 351-362. It writes the new spec later, at line 377. No lock or compare-and-swap covers the time between the check and the write.
Two editors can send expectedSha256 with the same base hash at the same time. Both checks pass, and the second write silently replaces the first. That is the lost update that the API contract excludes ("the server writes nothing and returns 409"). Guard the check and the write with one per-file lock, or move the comparison into dagRepository.UpdateSpec.
A process-local lock protects only one server process. For more than one frontend instance, the repository must do the compare-and-swap.

Make the --outputs-from scope match the outputsFromRunId rule.
Line 327 says that --outputs-from "carries the outputs of every skipped step". Line 299 and line 361 give a different rule. Under that rule, only skipped steps that a selected step depends on carry outputs. A skipped step after the selection carries nothing. carryingSteps in internal/intake/steps.go implements the narrower rule. The CLI help in internal/cmd/start.go (lines 65-66) and skills/dagu/references/cli.md (line 24) also say "every skipped step". Readers get two different rules from the same spec.

Review comment at @specs/013-step-run.md at line 327:
Update the `--outputs-from` description to specify that it carries the work
directory and outputs only from skipped steps that a selected step depends on.
Align the wording with the narrower rule implemented by `carryingSteps` and keep
the CLI help and reference documentation consistent.

extracted `steps.checkout.outputs.order_number` value is not interpolated into a
shell command; write it with the supported `file.write` mechanism or pass it

Keep the extracted order number out of the shell command.
If the page supplies an order number containing $(...), Dagu inserts that text before the shell runs. The shell then executes the command substitution, despite the double quotes. Write the value with file.write, or pass it as an environment variable and print that variable instead. (raw.githubusercontent.com)

Use graph mode for the router fixture.
type: chain does not allow router.route steps. This fixture cannot serve as a valid routing workflow. Change the mode to graph, or replace the router if the fixture must test chain mode. (docs.dagu.sh)

Allow the output file to be written on later runs.
After the first run creates out.json, a second run fails at file.write because its overwrite default is false. Set overwrite: true for this fixed output path. (raw.githubusercontent.com)

Summary
This PR adds 43 YAML fixture files under
ui/src/features/visual-editor/doc/__tests__/fixtures/. It adds no code and changes no existing file.Why
The tests of the YAML document model need real workflow files with odd forms. They are kept apart so that the code PRs stay small. The fixtures are read by the document model tests that start in PR 11; the model code itself comes in PR 10.

invalid-yaml.yaml, which is invalid on purpose.Pay attention to fixtures that contain secrets or host paths. None is expected.
Tests
No test file in this PR. The fixtures are data for the tests in PR 11 and later.
Screenshots
No visible UI change in this PR. The document model that reads these files drives the editor shown in the final UI.
