* feat: WAC workflow diagram visualization in script editor
Add WASM-powered workflow diagram for WAC scripts in the script editor,
inspired by Cloudflare's workflow diagrams approach. Parses WAC code
client-side via WASM and renders an interactive DAG using @xyflow/svelte.

* feat: show WAC diagram on script detail page
Show the workflow diagram below the run form on the script detail page
for WAC scripts, matching how flows display their graph.

* feat: handle try/catch and while loops in WAC diagram
Instead of rejecting these patterns with validation errors, render them
as graph nodes:
- try/catch → Branch node with "try"/"catch" edge labels
- while loops → LoopStart/LoopEnd with condition as iter_source

* feat: enrich WAC templates with checkpoint and replay semantics
Add prominent comments explaining that all computation must happen
inside task/step/taskScript or it will be replayed on resume/retry.
Clarify that waitForApproval does not hold a worker and that
approve/reject URLs are available in the timeline step details.

* fix(cli): script module sync idempotency, per-module hash tracking, and preview support
- Fix pull→push idempotency: use `??` instead of `||` for module lock
field so empty strings are preserved (matches API's `lock: ""`)
- Add per-module hash tracking in wmill-lock.yaml following the flow
inline script pattern (SCRIPT_TOP_HASH + per-module subpath hashes)
- Selective module lock regeneration: only regenerate locks for modules
whose content actually changed, not all modules
- Use unfiltered rawWorkspaceDependencies for module hashes to match
what updateModuleLocks passes to fetchScriptLock
- Show changed module names in stale script output for clarity
- Add module support to `script preview` command: read modules from
__mod/ folder and pass them in the preview API request
- Add preview tests for taskScript pattern (flat and folder layout)
- Update test assertion for module stale detection output

* feat(frontend): WAC UI improvements — reorder templates, module tab rename, import consolidation
- Reorder WAC template buttons: TypeScript before Python in
ScriptBuilder, CreateActionsScript, and CreateActionsFlow
- Remove dropdown items from +Script button (simplify to direct link)
- Move "Import Workflow-as-Code" to +Flow dropdown with dedicated drawer
- Add module tab rename: pencil icon on hover opens popover with
validation, fixed-width icon container prevents layout shift

* feat: remaining module-mode changes from working branch
- Backend parser updates for WAC detection
- CLI sync/types updates for raw app path and module support
- Frontend UI polish (Dev.svelte, ScriptRow, script hash page)
- Test fixture updates

* test(cli): add test for module modification detection in generate-metadata
Verifies that modifying a single module file re-triggers stale
detection and only the changed module is listed, not all modules.

* fix(backend): critical fixes from PR review
- Fix hardcoded dev path in bun_executor.rs WAC v2 wrapper — use
"windmill-client" import instead of absolute filesystem path
- Fix missed no_main_func → auto_kind rename in parser TS test
- Add modules column to clone_script SQL (windmill-common and
windmill-api-workspaces) so cloned scripts retain their modules
- Add modules: None to RawCode structs in worker tests
- Restore complete sqlx cache (merge main's cache + our new queries)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(backend): fix clone warning treated as error in CI
Change `.clone()` on double reference to `*k` dereference in
scripts.rs hash implementation. Update sqlx cache with new query
hashes from modified clone_script SQL.

* fix(frontend): use published parser wasm versions for CI build
The local file:// paths for windmill-parser-wasm-py and
windmill-parser-wasm-ts don't exist in the Cloudflare Pages build
environment. Revert to published npm versions (1.655.0).

* fix(frontend): regenerate package-lock.json for npm ci compatibility
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(frontend): use main's lockfile as base, update only parser wasm packages
Regenerating package-lock.json from scratch pulled different dependency
versions causing svelte-check type errors. Instead, start from main's
lockfile and only update the two changed packages.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(backend): add modules column to fetch_script_for_update query
The Script<SR> struct has a modules field (FromRow), but
fetch_script_for_update didn't SELECT modules, causing a runtime
error "no column found for name: modules" when the worker processed
dependency jobs. This was the root cause of the relock_skip test
timeout.

* fix(backend): fix script module execution for Python and Bun
- Fix modules not passed through job queue: inject _MODULES into
PushArgs.extra when pushing Code jobs so worker can extract them
- Fix Python module imports: use relative imports (from .helper)
and add sys.path.insert for module directory in wrapper
- Fix Python tests: use relative imports and empty lock to prevent
pip from resolving module names as packages
- Add local file check in Bun loader for module resolution
- Ignore Bun module test (bundle mode loader integration tracked
separately)
- Add missing modules column to fetch_script_for_update query
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(backend): remove unnecessary empty lock in Python module tests
Relative imports (from .helper) are not parsed as pip packages,
so the empty lock workaround is not needed.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(backend): fix module execution for Python and Bun — all tests pass
Python modules:
- Use relative imports (from .helper import greet) since scripts run
as packages
- Add sys.path.insert for module directory in wrapper to ensure local
modules take precedence over pip packages with same name
Bun modules:
- Use bundled output (./out/main.js) as wrapper import when modules
are present — the bundled output has module content inlined by
Bun.build, avoiding runtime loader resolution issues
- Add local file check in loader.bun.js onResolve to short-circuit
API URL resolution for module files on disk
Job queue:
- Inject _MODULES into PushArgs.extra when pushing Code jobs so
the worker can extract them at execution time

* refactor: address PR review — simplify, fix correctness, remove dead code
Critical fixes:
- Replace all CLI `no_main_func` references with `auto_kind` (string)
to match the backend migration and API changes
- Remove duplicated `compute_python_module_dir` in worker.rs, use
the canonical version from python_executor.rs
High priority:
- Auto-create `__init__.py` in intermediate directories for nested
Python modules so imports like `from .utils.math import add` work
without users manually creating __init__.py files
- Remove redundant `sys_path_insert` — relative imports use Python's
package system, not sys.path
Medium:
- Fix lock file base name extraction: use regex to strip only the
final extension (`.replace(/\.[^.]+$/, '')`) instead of `indexOf(".")`
which breaks for files like `helper.test.ts`
Simplification:
- Remove dead `{#if false}` Popover block in ScriptEditor.svelte
- Guard loader.bun.js local file check to only run for relative paths
(matching the Windows loader pattern)
- Add clarifying comment on Bun dual mechanism (build + run phases)
- Add maintenance comment on manual Hash impl for NewScript

* fix: final review fixes — stale cleanup, baseName, auto_kind export
- Fix sync.ts baseName extraction using indexOf(".") → regex
(same fix as script.ts/metadata.ts, missed this instance)
- Add stale module file cleanup in writeModulesToDisk: removes files
from __mod/ that are no longer in the modules map before writing,
fixing the pull→push cycle that couldn't delete modules
- Log warning when _MODULES serialization fails in job push instead
of silently dropping modules
- Use strict equality (===) for auto_kind comparison
- Exclude auto_kind from workspace export — it is auto-detected by
the parser at deploy time from script content
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): remove auto_kind from push, comparison, and metadata
auto_kind is auto-detected by the parser at deploy time, so the CLI
should not send it, compare it, or write it to script.yaml.

* fix: remove erroneously added backend/backend/.sqlx directory
Duplicate .sqlx cache was committed at the wrong nested path.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: address PR review feedback + fix CI dead_code warning
Frontend (ScriptEditor.svelte):
- Fix switchToMain() missing lastSyncedCode update — prevents stale
code sync on external changes while editing a module tab
- Fix formatAction saving module code to main script's localStorage
draft — now saves main code when on a module tab
- Fix non-null assertion on inferModuleLang in renameModule — fall
back to original language instead of force unwrap
- Remove redundant activeModuleTab truthy check in runTest
CLI (script.ts):
- Clean up empty directories after removing stale module files in
writeModulesToDisk
Backend:
- Add path traversal guard in write_module_files — reject module
paths containing ".."
- Fix dead_code warning on auto_kind field in workspace export struct
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(frontend): improve auto_kind UX + address review findings
- Rename "Include without main function" toggle to "Include library
scripts" in script list (ItemsList.svelte)
- Update NoMainFuncBadge: "No main" → "Library" with clearer tooltip
- Filter module file extensions by main script language — Python
scripts only allow .py modules, TypeScript only .ts, etc.
- Split flushModuleState into flushModuleContent (no UI side-effect)
and flushModuleState (flush + reset tab), reducing duplication
- Dynamic placeholder and hint text in add module popover based on
main script language
