Trim whitespace around the Registry token in the publish job

The first 1.4.4 publish run failed with "Invalid personal access token"
although the secret was present and unchanged; the previous action passed the
value unquoted, which dropped surrounding whitespace. Strip it explicitly and
log only the stored and used lengths.

-Registry review remains open in [issue #217](https://github.com/Comfy-Org/registry-backend/issues/217).
 Registry publication, security-review status and the version offered by Manager are
-separate states; Manager may offer an older version while review is pending.
-
-### Updating to 1.4.1
-
-- **BV Text Log Writer** accepts `.txt`, `.json` and `.log` names only. Rename
-  logs that used other endings; a rejected name fails the node with a clear error.
-- Regional LoRA stacks and Civitai metadata hashes accept `.safetensors` files
-  only, inside the configured ComfyUI LoRA folders. Convert pickle-based LoRAs
-  (`.pt`, `.ckpt`, `.bin`) before referencing them.
-- **BV Remote LLM Provider** lost its endpoint widget. Fixed profiles keep their
-  catalog address. For **OpenAI Compatible**, open **Configure API Key**, enter
-  the destination there and save the key again. For **Local OpenAI Compatible
-  (Custom)**, set `profile_defaults.local-openai-compatible.custom_endpoint` in
-  `remote_llm_settings.json` when the catalog loopback address does not fit.
-  Saved workflows load unchanged apart from the dropped endpoint value.
-- Restart ComfyUI and reload the browser after updating both backend and frontend.
-
-### Updating to 1.4.0
-
-- Enable **Global** in the intended LoRA Registry. Only one Registry may be active
-  across the workflow and its Subgraphs. New Registries start with Global off;
-  conflicting saved selections require an explicit choice, never a load-order winner.
-- The Regional Editor's **Globalen Stack anwenden** checkbox defaults to on.
-  Turning it off skips automatic Global LoRAs for that editor while preserving
-  manually selected normal stacks. Supply original MODEL/CLIP inputs when opting
-  out; already applied weights cannot be undone by this checkbox.
-- With **BV Regional Native Conditioning**, connect the source MODEL input and
-  use its **MODEL output (slot 2)** for the sampler when applying Global LoRAs.
-  Positive and negative outputs remain in slots 0 and 1. Model-specific attention
-  nodes prepare their own MODEL/CLIP through the same automatic service.
-- Existing basis groups retain their identities, order, strengths and enabled
-  states inside the Global area. Existing manual global assignments remain
-  separate; they are not copied into the fixed Global stack.
-- Registry dialog changes save immediately to the node configuration, including
-  Undo/Redo and catalog additions. Invalid drafts keep the last valid saved state.
-  Save the workflow separately to persist changes to disk.
-- Restart ComfyUI and reload the browser after updating both backend and frontend.
-  The catalog identifies an older running backend instead of presenting missing
-  routing fields as a compatibility result.
-
-The following safeguards from 1.3.0 still apply:
-
-- Re-enter existing API keys for custom OpenAI-compatible providers through
-  **Configure API Key** and confirm the displayed destination. Keys are bound to
-  that full endpoint; redirects are blocked. Fixed-provider legacy keys retain
-  their catalog destination.
-- **BV Remote LLM Provider** has no endpoint widget any more. The destination is
-  decided by the backend only: the catalog address for fixed profiles, the
-  approved API-key binding for custom bearer profiles, and the optional
-  `profile_defaults.<profile>.custom_endpoint` entry in `remote_llm_settings.json`
-  for the key-less local custom profile. A workflow cannot select a destination.
-- Regional LoRA stacks accept `.safetensors` files only, and only inside
-  configured ComfyUI LoRA folders, including `extra_model_paths.yaml` entries.
-  Register additional folders there; absolute paths within configured folders
-  remain supported. Pickle-based formats (`.pt`, `.ckpt`, `.bin`) are rejected
-  with a clear error, so no LoRA reaches `torch.load`. The same rule applies to
-  the LoRA hashes that BV Regional Image Save embeds as Civitai metadata; files
-  outside those folders are never read.
-- Text logs reject linked log files and linked `bv_logs` directories. Use an
-  ordinary log directory below the configured ComfyUI output root. Log names
-  must end with `.txt`, `.json` or `.log`; other endings are rejected.
-
-Keep ComfyUI and its settings routes restricted to trusted users, and review
-imported workflows before running them. These safeguards do not constitute
-Registry approval or a guarantee that arbitrary workflows are safe.

 ## Feature overview
 
+### Standalone text and writing assistance
+
+**BV Text** (`utils`) provides a native multiline text field and a STRING output,
+without a Regional document. Use the controls below the field to select a provider
+and model, translate or improve wording, and undo the last replacement. Provider
+credentials use the shared private backend storage; writing settings stay in the
+node's workflow properties. Assistance runs only when clicked. Queue execution
+returns the stored text unchanged. Newer manual edits are preserved if a response
+or Undo would overwrite them. Disconnect a linked text input before editing the
+local field with writing assistance.
+
+Writing settings include General, Krea 2 and Custom prompt profiles. Selecting a
+curated profile replaces the editable system prompt; the provider and language
+settings are independent. Edited templates are marked Customized. Saved workflows
+keep their actual system prompt until you explicitly select or reset a profile.
+The Krea 2 preset adapts the [official prompting guidance](https://github.com/krea-ai/krea-2/blob/main/docs/prompting.md)
+for conservative rewriting: natural language, existing details and quoted image
+lettering, without inventing scene content. Other model profiles remain pending.

 ## Changelog
 
 The README keeps the four most recent version entries. The complete history is
 maintained in the [Wiki changelog](https://blackvortexai.github.io/bv_nodepack_wiki/reference/changelog).
 
+### 1.4.4 — 2026-09-13
+
+- Add **BV Text**, a native multiline text node with a STRING output and optional
+  writing assistance: translate or improve the field through the configured Remote
+  LLM provider, undo the last replacement, and switch between General, Krea 2 and
+  Custom prompt profiles. Assistance runs only when clicked; queue execution returns
+  the stored text unchanged. The assistance route is management-gated, reads at most
+  192 KiB, keeps one request in flight and can only reach the endpoint the stored API
+  key was approved for.
+- Reuse prepared MODEL/CLIP state for Krea 2 and Anima LLLite consumers across
+  repeated runs when the LoRA stack, strengths and files are unchanged, instead of
+  preparing again; any file, option or patch change invalidates the entry.
+- Give every Remote LLM request one wall-clock budget that covers connecting, the
+  status line and headers, chunked framing and the body. A provider that stalls or
+  trickles data is cut off at the configured timeout and the request fails; the
+  writing-assistance slot is freed for the next request. Writing assistance uses the
+  profile's configured `timeout_seconds` instead of a fixed 60 seconds.
+- Read every JSON request body of the pack's routes through one bounded reader with a
+  route-specific limit (completion search 16 KiB, catalog channel 1 KiB, LUT install
+  4 KiB, API key 16 KiB, writing assistance 192 KiB); oversized or malformed bodies
+  are refused with 413 or 400 before any work starts. Infinite or absurd `limit`
+  values in a completion search fall back to the default instead of failing.
+- Ship `SECURITY.md` with the pack's security model: management routes, private
+  storage, the deliberately public catalog refresh and startup fetch, file and
+  download boundaries, the frontend bundle and the release process.
+- Start the frontend bundle with a readable header naming the vendored libraries and
+  versions, and list all eight bundled libraries with license, copyright and lockfile
+  integrity in `THIRD_PARTY_NOTICES.md`. The libraries themselves are unchanged.
+- Turn the Registry scan replica into a hard test: a pattern match outside the
+  documented baseline fails the suite. Add a test of the packaged file set, and
+  exclude design references, brand sources and a TypeScript declaration from the
+  package. Both are compatibility and packaging checks, not security tests.
+- Publish only from a commit whose Validate run succeeded, through a publish job with
+  read-only permissions and a pinned comfy-cli, writing a manifest of the packaged
+  files before the upload and comparing the archive the Registry stored afterwards.
+  Validate additionally audits the UI dependencies and verifies that a rebuild emits
+  nothing but the committed bundle.
+- Record the Registry review status in the README and note that API keys saved before
+  1.4.2 on a server other machines could reach should be rotated.
+
+### 1.4.3 — 2026-09-08
+
+- Make the **BV Seed** action buttons respond to normal clicks again, also when
+  the seed is exposed on a Subgraph node. Since ComfyUI frontend 1.49 the canvas
+  treats any pointer movement later than 32 ms after pressing as a drag, so
+  ordinary clicks on canvas buttons were often lost; the seed buttons now take
+  over the press and fire on release inside the button.
+- Trim the frontend bundle: the JSON editor now loads only Prism's core and
+  JSON grammar instead of the full Prism build, which drops the unused file
+  loader from the shipped script.
+- Refactor three backend call sites to plain imports and a single download-host
+  constant: the environment lookup for the autocomplete dataset, the aiohttp
+  session in the LUT downloader and the catalog source URLs, which are built
+  from the host constant and stay byte-identical. No behaviour, no limit and
+  no safeguard changes; these are the exact literals the Registry's automated
+  scan reported for 1.4.1 and 1.4.2.
+- Add a repository test that mirrors the Registry's automated scan over the
+  packaged file set and compares it with a checked-in baseline, so new scanner
+  matches are visible before publishing. It is a compatibility check, not a
+  security test.
+
+### 1.4.2 — 2026-09-08
+
+- Store Remote LLM settings and API keys, the response cache, LUT working
+  catalogs and the LoRA header cache in ComfyUI's private System User directory
+  `user/__bv_nodepack/`, with a verified one-time migration from the public
+  `user/default/bv_nodepack/` folder. Without the System User API the pack fails
+  closed instead of using the public folder.
+- Accept management requests (API keys, LUT install, catalog channel) only from
+  local clients of a loopback-only ComfyUI, with an explicit operator opt-in file
+  for `--listen` servers. Read routes and the catalog refresh stay open.
+- Download LUT catalogs and files only from `raw.githubusercontent.com`, checked
+  before any connection, and never follow redirects.
+- Apply one folder-containment rule to LoRA previews, sidecars, Civitai model
+  hashes and the LUT install directory, resolving links before use.
+- Bound raster masks to 32 megapixels, deduplicate autocomplete dataset
+  selections, check LUT existence before downloading and limit parallel installs.
+- Exclude `.github/` from the Registry package and remove outdated example
+  workflows, fixtures and scripts from the runtime repository.

+### Updating to 1.4.4
 
-### 1.2.3 — 2026-09-01
+- Restart ComfyUI and reload the browser after updating both backend and frontend so
+  the rebuilt bundle and the new **BV Text** node are picked up.
+- Remote LLM requests now fail at the configured timeout even when the provider keeps
+  sending data slowly. If a legitimate provider needs longer, raise `timeout_seconds`
+  in the private `remote_llm_settings.json`; the allowed range is unchanged.
+- Read [SECURITY.md](SECURITY.md) once: it describes which routes are public, what
+  the pack fetches at startup, and why. If an API key was saved before 1.4.2 on a
+  server other machines could reach, rotate it.
+- Writing-assistance settings, including the style guide, are stored in the node's
+  workflow properties and therefore travel with saved workflows and image metadata.
+  Do not put secrets into them.
 
-- Harden the Comfy Registry package by excluding development tests and UI source
-  files while retaining the committed runtime bundle. Runtime behavior is unchanged.
+### Updating to 1.4.3
 
+- Reload the browser after updating so the seed button fix is picked up. If other
+  canvas buttons still need several clicks, raise the ComfyUI setting
+  `Comfy.Pointer.ClickBufferTime` from 32 to 150 ms (the pre-1.49 default).
+- Restart ComfyUI and reload the browser after updating
+  both backend and frontend so the rebuilt bundle is picked up.
+
+### Updating to 1.4.2
+
+- BV runtime files move from `user/default/bv_nodepack/` to ComfyUI's private
+  System User directory `user/__bv_nodepack/`, which ComfyUI's own `/userdata`
+  routes do not serve. The move happens once at startup: settings, API keys, LUT
+  catalogs and the LoRA header cache are copied, verified and then removed from
+  the public folder; the Remote LLM response cache is deleted there and rebuilt
+  on demand. If a private file already exists and differs, the public content is
+  kept next to it as a `*.recovered` file that is never loaded. The startup log
+  lists every migrated, removed, recovered or failed file. Until this update the
+  public files were potentially readable through `/userdata` by anyone who could
+  reach the server; consider rotating API keys if that applies to your setup.
+- On a ComfyUI without the System User API (older versions) BV neither reads nor
+  writes the public folder: API-key providers and catalog updates are disabled
+  with a clear message, everything else keeps working, and existing public files
+  stay where they are until you update ComfyUI or remove them yourself.
+- Management actions (saving or deleting API keys, installing LUTs, switching the
+  catalog channel) are accepted only from clients on the same machine while
+  ComfyUI listens on a loopback address, like ComfyUI-Manager's local mode. For
+  a `--listen` server, either edit the files in `user/__bv_nodepack/` directly or
+  create `admin_settings.json` there with
+  `{"schema": "bv.admin.settings", "version": 1, "allow_remote_management": true}`,
+  which deliberately opens these actions to every client that can reach the server.
+- LUT catalogs and downloads come only from `raw.githubusercontent.com`, without
+  following redirects. Foreign catalogs are not supported; place your own `.cube`
+  files in the LUT folder instead.
+- Previews, sidecars and model hashes follow the same folder containment as LoRA
+  loading: a link inside a model folder that leads outside it is ignored.
+- Restart ComfyUI and reload the browser after updating both backend and frontend.
+
+### Updating to 1.4.1
+
+- **BV Text Log Writer** accepts `.txt`, `.json` and `.log` names only. Rename
+  logs that used other endings; a rejected name fails the node with a clear error.
+- Regional LoRA stacks and Civitai metadata hashes accept `.safetensors` files
+  only, inside the configured ComfyUI LoRA folders. Convert pickle-based LoRAs
+  (`.pt`, `.ckpt`, `.bin`) before referencing them.
+- **BV Remote LLM Provider** lost its endpoint widget. Fixed profiles keep their
+  catalog address. For **OpenAI Compatible**, open **Configure API Key**, enter
+  the destination there and save the key again. For **Local OpenAI Compatible
+  (Custom)**, set `profile_defaults.local-openai-compatible.custom_endpoint` in
+  `remote_llm_settings.json` when the catalog loopback address does not fit.
+  Saved workflows load unchanged apart from the dropped endpoint value.
+- Restart ComfyUI and reload the browser after updating both backend and frontend.
+
+The following safeguards from 1.3.0 to 1.4.4 apply together:
+
+- All BV runtime files (`remote_llm_settings.json`, `remote_llm_secrets.json`,
+  `admin_settings.json`, LUT catalogs, caches) live in ComfyUI's private
+  `user/__bv_nodepack/` directory, which ComfyUI's `/userdata` routes do not
+  serve. BV itself reads nothing from the public `user/default/` tree any more;
+  other custom nodes or routes are outside this guarantee.
+- Management routes (API keys, LUT install, catalog channel) answer only local
+  clients of a loopback-only ComfyUI unless `allow_remote_management` is set in
+  the private `admin_settings.json`. This mirrors ComfyUI-Manager's local mode
+  and is not an authentication: a reverse proxy on the same machine is local.
+- Re-enter existing API keys for custom OpenAI-compatible providers through
+  **Configure API Key** and confirm the displayed destination. Keys are bound to
+  that full endpoint; redirects are blocked. Fixed-provider legacy keys retain
+  their catalog destination.
+- **BV Remote LLM Provider** has no endpoint widget any more. The destination is
+  decided by the backend only: the catalog address for fixed profiles, the
+  approved API-key binding for custom bearer profiles, and the optional
+  `profile_defaults.<profile>.custom_endpoint` entry in the private
+  `remote_llm_settings.json` for the key-less local custom profile. A workflow
+  cannot select a destination.
+- LUT catalogs and LUT files are downloaded only from
+  `raw.githubusercontent.com`, checked before any connection, without redirects.
+- Regional LoRA stacks accept `.safetensors` files only, and only inside
+  configured ComfyUI LoRA folders, including `extra_model_paths.yaml` entries.
+  Register additional folders there; absolute paths within configured folders
+  remain supported. Pickle-based formats (`.pt`, `.ckpt`, `.bin`) are rejected
+  with a clear error, so no LoRA reaches `torch.load`. The same folder rule
+  applies to LoRA previews, metadata sidecars, the LoRA and model hashes that
+  BV Regional Image Save embeds as Civitai metadata, and the LUT install
+  directory: links are resolved first, and a file that resolves outside its
+  configured folders is never read or written.
+- Every Remote LLM request has one wall-clock budget; every JSON request body the
+  pack accepts is read with a route-specific size limit before it is parsed.
+- Text logs reject linked log files and linked `bv_logs` directories. Use an
+  ordinary log directory below the configured ComfyUI output root. Log names
+  must end with `.txt`, `.json` or `.log`; other endings are rejected.
+
+Keep ComfyUI and its settings routes restricted to trusted users, and review
+imported workflows before running them. These safeguards do not constitute
+Registry approval or a guarantee that arbitrary workflows are safe. If an API key
+was saved before 1.4.2 on a server that other machines could reach, rotate it: the
+1.4.2 migration moved the key out of the public tree but cannot tell whether it was
+read before. [SECURITY.md](SECURITY.md) describes the complete model, including the
+deliberately public catalog refresh and the startup catalog fetch.

+# Security
+
+This file describes the security model of BV Node Pack as shipped: what the pack's
+own entry points accept, where they write, which network destinations they use and
+which limits apply. It is a description, not a certification, and the Comfy Registry
+review status of a version is recorded separately from it. The dated long form with
+the route-by-route evidence table lives in the wiki:
+[Security and Registry evidence](https://blackvortexai.github.io/bv_nodepack_wiki/reference/security-and-registry-evidence/).
+
+## Scope and supported configuration
+
+BV Node Pack runs inside ComfyUI and inherits its process permissions, HTTP exposure
+and installed extensions. It is not a sandbox for hostile workflows, plugins, model
+files or users with access to the host file system. The controls below apply to
+BV-owned entry points; ComfyUI's own loaders and other extensions have their own
+contracts.
+
+Releases before 1.4.1 and 1.4.2 do not contain the file-access, private-storage and
+management-route hardening described below. The version a Registry-based installer
+offers is the newest version the Registry lists as active, which can be older than
+the newest release. An older active version is not more secure than a newer flagged
+one; read the changelog of the version you install.
+
+## Server access and provider credentials
+
+Management routes (saving or deleting API keys, installing LUTs, switching the catalog
+channel, writing assistance) answer only when ComfyUI listens on loopback addresses
+exclusively and the request's own socket peer is a loopback address. This is a
+reachability restriction, not user authentication. A reverse proxy on the same host
+satisfies both checks for remote clients; the operator must authenticate or restrict
+access at that proxy. Forwarded headers and the client-supplied ComfyUI user header
+are ignored on purpose, because a client can set them freely.
+
+The private `admin_settings.json` can enable remote management for a `--listen`
+server. This opens the management routes to every client that can reach the server;
+it does not create per-user authorization. There is no separate management token.
+
+Provider secrets, private settings, working catalogs and caches are stored through
+ComfyUI's private System User directory, which the public `/userdata` routes do not
+serve. Without that API the pack fails closed instead of using the public user tree.
+Private storage protects against other HTTP clients, not against the operating-system
+account, other extensions in the same process or the host administrator. Keys that
+were stored before 1.4.2 lived under the public `user/default/` tree; if the server
+was ever reachable from other machines while such a key existed, rotate the key. The
+migration moved the files; it cannot tell whether anyone read them.
+
+Each API key is bound to the endpoint it was approved for. Workflow fields, writing
+assistance requests and the settings file cannot redirect a key to another
+destination. Remote endpoints use HTTPS with normal certificate verification; plain
+HTTP is accepted for loopback endpoints only. Redirects are rejected. Every provider
+request has one wall-clock budget, the configured timeout, that covers everything
+after the provider's host name has been resolved: connecting to each resolved
+address, the TLS handshake, waiting for the status line and headers, and reading the
+body. Responses are capped in size; a provider that stalls or trickles data is cut
+off and the request fails. Name resolution itself is bounded by the operating system,
+not by this budget.
+
+Using the Prompt Enhancer or the writing assistance intentionally sends the selected
+prompt text, and for writing assistance the configured style guide, to the configured
+provider. Both are the only routes that send user content to a third party, both are
+management-gated, and the effective destination is shown before the first use. Do not
+put secrets into prompts or style guides: node properties are saved with the workflow
+and embedded in image metadata.
+
+## Files, downloads and public endpoints
+
+The pack's LoRA loaders resolve names inside the configured ComfyUI LoRA directories,
+follow no links outside them and load `.safetensors` files only through the safe
+loader. The Text Log Writer writes only below its log directory, accepts only text
+extensions, and refuses names that resolve to links or existing directories. LUT
+installation accepts validated catalog entries only, downloads from one fixed host,
+rejects redirects and checks size, hash and format before the file becomes visible.
+Model patches for the optional LLLite integration are resolved through ComfyUI's
+configured directories and loaded by ComfyUI's own loader.
+
+The catalog refresh route is deliberately public: any client that reaches ComfyUI can
+ask the pack to fetch the current LUT catalog from its fixed source and store it in
+private working storage. The pack also requests one such refresh when ComfyUI starts.
+Both operations are bounded in size and time, use one fixed host, follow no redirects
+and take no URL from the caller. They are documented here as a decision, not as an
+oversight; an installation that must not contact the network at startup should block
+that host at the network level.
+
+Read routes (catalogs, model lists, provider status) are public. They expose the
+names of configured models and the provider endpoints in use, not key material.
+Catalog reads can create the download directory and inspect installed files.
+
+Every JSON body the pack's routes accept is read with a route-specific size limit
+before it is parsed, and rejected with a 413 or 400 status when it is larger or not a
+JSON object. These limits protect the server from oversized requests; they do not
+provide per-user isolation on a shared server.
+
+## Frontend bundle and third-party code
+
+`js/bv_nodepack.core.js` is built by Vite from the TypeScript sources in `ui/src`. It is
+minified, not obfuscated: the bundle starts with a readable header naming the
+vendored libraries and their versions, the build is reproducible from the lockfile,
+and `THIRD_PARTY_NOTICES.md` lists every bundled library with license and integrity
+hash. BV refactors its own code freely, but does not edit vendored library code,
+including not to change how automated code scans read it.
+
+## Release process
+
+A release is published only from a commit whose validation workflow passed, by a
+publish job with read-only repository permissions and a pinned publishing tool. The
+job writes a manifest of the packaged files with their hashes, refuses to publish
+when a development-only or secret-looking file would be included, and after the
+upload compares the archive the Registry stored with that manifest. The test suite
+includes a lexical replica of the patterns the Registry scan reported for this pack;
+it fails on any match outside a documented baseline. That replica is a compatibility
+check with written exceptions, not a security test, and it cannot predict the
+Registry's decision.
+
+## Reporting a concern
+
+Please open an issue in the
+[bv_nodepack repository](https://github.com/BlackVortexAI/bv_nodepack/issues) naming
+the affected release, the entry point, the input and the observed effect. Do not post
+credentials, private prompts or sensitive workflow files. If a report needs
+confidential handling, say so in the issue without the details and the maintainer will
+name a private channel. The Registry review history is in
+[registry-backend issue 217](https://github.com/Comfy-Org/registry-backend/issues/217).
