Follow-up to #6604 (merged). Builds the Security policy out so it
actually enforces, driven from the editor.
## What it does
- **Run on upload or export** — a single choice in the wizard: enforce
when a file is uploaded, or just before it's exported.
- **Output** — enforced result is a **new version** of the file
(default) or a **new file**, with optional filename
prefix/suffix/auto-number ("Output filename" subsection; auto-number
only for new files).
- **Export enforcement** — exporting an export-mode file runs the policy
first and downloads the enforced result; never hard-blocks (on failure
the original downloads). For new-version policies the in-editor file is
versioned too. Covers every export path incl. multi-file ZIP. A toast
(glowing in the policy's accent while it runs) reports progress and
fades after ~10s.
- **Affordances** — a freshly enforced file briefly glows its policy
accent and carries a shield badge.
- **Config tidy-up** — removed the unwired Security setting fields + the
wizard's review step; "Upgrade to enterprise" on locked categories;
category accent in the detail/wizard headers.
## Notes
- Builds on the manual-only (client-driven) policy model from #6587
(`trigger: null`, metadata in `output.options`), adding the `runOn`
field + export-time enforcement.
- The page-editor merge-export (no single source file) enforces +
downloads but doesn't version in place.
## Verification
typecheck (core + proprietary), eslint, prettier; proprietary suite
(105) green; flows checked in-app.
Follow-up to #6598 (squash-merged into `SaaS`). These are the policy
refinements made after that merge, against the current `SaaS` tip.
## Changes
- **Simplify Security config + plain-language info buttons** — Redact
config reduced to the PII field; Sanitise has no config
(JavaScript-removal only) with a non-technical info button; per-tool
info buttons reworded to match the tool-steps style.
- **Hide 'Flatten PDF pages to images' from the watermark policy
config** — new `PolicyWatermarkConfig` wrapping the watermark settings
with the flatten checkbox gated off.
- **Flatten-to-image on by default for redact + watermark** — both
normalise `convertPDFToImage: true` on mount.
- **Self-heal a stale backing folder** — `ensurePolicyFolder` recreates
a backing folder whose `folderId` no longer resolves (preferring the
backend's stored automation), instead of hanging Edit Settings on a
permanent "Loading…".
- **Version the input file on 'new version' output mode** — completed
runs whose policy output mode is `new_version` replace the input file
with a versioned child (origin tool `automate`) rather than adding a
separate file; falls back to a new file if the input is gone.
`outputMode` is plumbed through `PolicyState`, the local-cache default,
and backend reconciliation.
## Verification
- `typecheck:proprietary` + `typecheck:core` clean
- policy + hooks vitest: 17 passing
- eslint + prettier clean on all changed files
## Summary
Adds the **Policies** feature (proprietary, behind the
`POLICIES_ENABLED` flag): backend-driven enforcement that runs a fixed
tool pipeline on documents, docked in the right tool sidebar alongside
Tools.
## Highlights
- **Policy catalog** — 5 categories; **Security** is wired (redact PII +
sanitize), the others are marked "Coming soon".
- **Backend as source of truth** — policies persist via the Policies
engine (`/api/v1/policies`), one policy per category, with a local cache
+ offline fallback.
- **Auto-run** — enabled policies run on every uploaded file: dispatch →
poll → import outputs into the workspace.
- **Security redact config** — PII preset dropdown + custom word/regex
entry + advanced options; tool params map to the backend endpoint
fields.
- **Activity feed** with retry on failures; **file badges** showing
which policies ran on a file (sidebar + files page), tinted to the
policy colour.
- Reuses the **Watched Folders** engine for each policy's backing
folder; policy-owned folders are filtered out of the Watched Folders UI.
## Notes
- Gated by `POLICIES_ENABLED` (true in proprietary, false in core) —
unreachable in the open-source build.
- Frontend-only diff; depends on the backend Policies engine and the
merged Watched Folders feature.
