Inline comments:
In `@js/manager-grid.js`:
- Around line 19-26: Update the shared value-processing boundary in
highlightKeywordsFilter to always decode entity-escaped text via the existing
DOMParser cache, removing the HTML-tag pattern guard. Preserve the rowItem cache
keyed by textKey and column, then assign the decoded cached value back to text
for all model and custom-node columns.
In `@prestartup_script.py`:
- Around line 469-472: Update the nh3 requirement-loading logic to default to
Requirement('nh3>=0.3.7'), catch OSError when reading requirements_path, strip
inline comments before parsing, and ignore InvalidRequirement lines while
continuing to search for a valid nh3 entry. Preserve the existing version check
so missing or invalid manifests still enforce the minimum and trigger the
ModuleNotFoundError installation path for outdated or absent packages.
In `@tests/test_message_sink_provenance.py`:
- Line 418: Update the is_error_var check in _call_sites() to recognize only
complete trusted errorMsg or err identifiers, rejecting suffixes such as errText
and errorMsg$raw while supporting JavaScript $ identifiers; retain the existing
escaped-value guard behavior.
In `@tests/test_notice_dependencies.py`:
- Around line 62-67: Update the requirement parsing in the test around the pip
and project dependency mappings to ignore lines that
packaging.requirements.Requirement cannot parse, including blank lines,
comments, and pip options. Import InvalidRequirement, add a local _requirements
helper that catches it and returns parsed requirements by name, and use that
helper for both requirements.txt and pyproject.toml dependencies while
preserving the existing explicit lookups.

- Line 416: Update the literal guard in the relevant test helper to recognize
only complete JavaScript string-literal arguments, rather than accepting
arguments that merely start with a quote; use a full-match pattern covering
escaped and unescaped non-quote characters and the expected closing syntax.
Extend test_error_guard_rejects_unclassified_arguments with the concatenated
string form to verify it is rejected.

with an instruction to install Chromium; retain the existing launch behavior
when the executable is available.

@coderabbitai review Please review current head 8eb7e7e. Automatic review paused after the previous head. The only subsequent change keeps the call-count inventory derived solely from REGISTRY while applying duplicate counts only to registered keys; the latest review thread has been answered. Source regression: 191 passed plus 221 subtests; integrated v3 regression: 235 passed plus 221 subtests. |

@coderabbitai review Retrying after the hourly limit. Please review current head 8eb7e7e; recorded coverage stops at 9a5d6e4. The remaining change makes the call-count inventory derive solely from REGISTRY. Latest source regression: 191 passed plus 221 subtests. The companion Flagged PR #3298 has since merged into main. |

@coderabbitai review Please review head 2f7d16f. The sole change since the reviewed head addresses the unparsed sink-call finding with a source-inventory guard and the two requested mutation cases. Both Red/Green checks and source/integration regressions passed; production files are unchanged. |

Purpose and scope
Node/model metadata, workflow names and error messages can become executable HTML in Manager dialogs. Render untrusted values safely while preserving readable text, formatted descriptions, valid links and search behavior.
Covers Custom Nodes, Model Manager, Node Usage Analyzer, snapshots, sharing links, update-result dialogs, Markdown descriptions and notices. Configuration-persistence fixes are already present in main through #3157.
Key changes
Validation approach
Python/Node tests execute production rendering and sanitization. Chromium tests load the actual grid modules and execute the update-completion handler against a DOM-backed dialog. Update-result checks cover both success and failure lists, quoted URLs, titles and missing-URL labels.
Search regressions exercise the actual node/model grid setup: encoded names remain searchable as displayed, while raw author/file values retain literal entities. Dependency checks simulate missing, outdated and supported versions with plain and commented manifests. Source inventories check complete selection/error arguments, occurrence counts and error-message assignments, and reject unparsed statically named sink calls such as quoted member access and returned-object calls. These checks are a bounded source inventory, not general JavaScript dataflow analysis. Mutation checks detect added raw values, including multiline selection markup and concatenations that retain an existing escape. Runtime tests separately verify rendering behavior.
Live Playwright scenarios use an isolated ComfyUI server, real routes, queue, installation and WebSocket completion. A local Registry provides metadata and harmless archives. They cover rendering, search/highlighting, Active installation, Flagged denial and preservation of manual settings edits. v3 runs without --enable-manager.
The new completion, search, commented-manifest and guard regressions fail before correction and pass afterward. Valid inputs remain covered alongside rejected inputs.
Validation results
Live checks use frontend 1.45.15 and single-tab sessions. The public Registry and external sharing uploads were not exercised in this rerun. Update All rendering is tested with completion events in an isolated browser; a live backend Update All operation was not run.
