Purpose and scope

A successful Registry install response previously allowed a Flagged CNR version to proceed. Require Flagged versions to satisfy the same installation conditions as Active versions, plus a server listening exclusively on loopback or an explicit administrator override. Covers glob and legacy installation, switching, updates, deferred startup and server-scheduled restores, plus legacy batch reinstallation.

The allow_flagged_nodepack_install option belongs in config.ini’s [default] section. It defaults to false; only case-insensitive true enables it, after restarting ComfyUI. The override is intended for a trusted private network and permits non-loopback listeners. It does not detect private networks or bypass common security checks, Registry refusals or Git/pip restrictions.

Key changes

  • Use status from the existing CNR install response. Check policy before changing the current pack and reuse that response for execution, without another Registry lookup.
  • Allow CNR release installation on non-local listeners at normal-or-lower security levels in both servers. Active/Pending releases use this common gate; Flagged releases must also pass the listener/override check. Strong security still denies all CNR installation requests, and Git/nightly retain their existing restrictions.
  • Validate legacy reinstallation before removal, then install and rerun the pack’s script. Both cores preserve files and activation state on policy denial, retain the reason in queue/update results and avoid retrying rejected restore targets.
  • Recheck deferred work against current startup settings and pass the resolved server permission to scheduled restore children. Standalone CLI retains its existing interface and local administrator behavior.
  • Show a short security-configuration denial in the UI. Only terminal logs provide the loopback listener and private-network override remedies, including restart instructions.

Affected modules: CNR metadata mapping, installation cores, server queues, startup processing, configuration and README. Deferred switches use stored status without refreshing it from the Registry. Older reservations without status require loopback-only listeners or the override; otherwise startup rejects them without changing the pack and tells the user to request installation again. Enabling an already installed identical version remains a local activation with no Registry lookup or installation script.

Validation approach

Core tests run production installation paths with controlled external responses. E2E uses actual HTTP requests, queues, ZIP installation, restart and CLI subprocesses, with a local Registry and isolated node paths, settings and databases.

Intent Observed result
Add restrictions only to Flagged Active/Pending controls install; Flagged needs loopback or override. Strong-security controls reject both Active and Flagged before metadata lookup.
Preserve state on denial Existing files, versions and activation state survive; no download or reservation is created.
Avoid duplicate lookups Count metadata requests through installation and restore; deferred switches make no additional lookup.
Preserve execution context Observe immediate file replacement versus deferred reservation, callback timing, standalone CLI behavior and actual server-scheduled restore children. Existing-version activation needs no Registry lookup or installation script.
Keep errors and settings correct Verify short UI errors versus terminal remedies, Registry refusal, listener edge cases, old reservations and configuration persistence.

Tests fail when status propagation is removed, Registry refusals are ignored, or reinstall script execution is suppressed. Immediate-switch checks fail when the execution flag is dropped, and missing-status reservations are tested under both allowed and denied startup settings. Restored code passes; successful Git reinstall cases cover both catalogue entries and the CNR repository fallback.

Validation results

Current source is 0c8f423 on manager-v4, which includes #3297. Its complete Git tree is identical to the verified UI + Flagged integration 6df4aa14. Integration results below were recorded on 1a04122a; the only difference is the strengthened legacy denial-response test, and production and policy E2E files are identical. Focused policy/configuration regressions were rerun on 0c8f423: 176 passed.

Scope Result
Pre-rebase standalone 0ceeec6, non-E2E regression 453 passed; 12 skipped; 3 inherited failures
UI + Flagged integration 1a04122a, non-E2E regression 569 passed; 12 skipped; the same 3 failures
Policy server E2E on 1a04122a, glob and legacy 108 passed; 12 skipped
Live legacy browser E2E on 1a04122a 7 scenarios passed; no uncaught browser exceptions

The three Git backup fixture failures also occur on unchanged manager-v4. The complete local regression suite is not green. The twelve non-E2E skips require a separate CLI environment. Eight policy E2E skips require a preinstalled pack under strong security; four exclude loopback from non-local Git checks. Strong-security denial is tested directly.

Ruff, OpenAPI, code-quality and Socket checks passed on 0c8f423. CLI E2E CI also passed on Ubuntu, Windows and macOS after rebasing onto the merged UI change.

Policy E2E uses a local Registry with real HTTP routes, queues, archive installation, deferred startup and CLI subprocesses. Separate Playwright scenarios exercise the integrated legacy UI, real installation and WebSocket completion, Active installation, Flagged denial and configuration preservation. Browser checks use frontend 1.45.15 and single-tab sessions; the legacy menu opens through its registered command because of an inherited toolbar issue.

Tests use Python 3.12 and ComfyUI 039ed38e on Python 3.10.20. The public Registry was not exercised in this run. Snapshot checks establish admission, extraction and denial-state preservation; fresh-snapshot install.py completion and file-lock/deferred-deletion handling remain outside this PR.

The existing deferred-deletion/state-consistency defect is tracked in #3301, including removal-result semantics, restart cleanup and regression acceptance criteria. The uninstall-failure test in this PR checks a reported failure; it does not establish correct reporting of a deferred deletion.

Review Change StackReview Change Stack

📝 Walkthrough

Walkthrough

The change adds flagged CNR version status handling, listener and configuration checks, updated install and reinstall flows for both manager trees, deferred restore enforcement, documentation, and unit and end-to-end tests.

Changes

Flagged CNR installation policy

Layer / File(s) Summary
Policy contract and configuration
comfyui_manager/common/cnr_utils.py, comfyui_manager/common/manager_security.py, comfyui_manager/*/manager_core.py, comfyui_manager/*/manager_server.py
CNR versions now carry status. Security helpers evaluate flagged versions and loopback listeners. The new configuration value is persisted and used by manager permission checks.
Glob installation and server enforcement
comfyui_manager/glob/manager_core.py, comfyui_manager/glob/manager_server.py
The glob manager validates CNR responses before side effects, reuses validated metadata, records status for deferred switches, and applies version-specific security levels.
Legacy installation and reinstall flow
comfyui_manager/legacy/manager_core.py, comfyui_manager/legacy/manager_server.py
The legacy manager validates CNR responses before changes, adds reinstall routing, separates Git and CNR paths, and preserves queued operation types.
Deferred switches and restores
comfyui_manager/prestartup_script.py, comfyui_manager/*/manager_core.py
Deferred switches store status and recheck permission. Snapshot restoration records failures, skips already processed switches, and runs install scripts only after successful authorization.
Documentation and automated validation
README.md, tests/test_flagged_nodepack_policy.py, tests/test_install_flags_config.py, tests/test_legacy_secgate_other_paths.py
The README documents the policy. Tests cover permission decisions, side-effect prevention, reinstall paths, deferred records, configuration persistence, and queue entry points.
End-to-end validation
tests/e2e/test_e2e_flagged_nodepacks.py
End-to-end tests cover both manager trees, listener and security combinations, restarts, snapshot restores, reinstalls, registry responses, and direct CLI operations.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to 0c8f4

Unspecified CNR installs can report no resolved version. A rare inherited reinstall failure also remains separately tracked, but this change does not materially worsen it. The PR is mergeable with these bounded issues acknowledged.

The PR is now rebased on manager-v4 after #3300; the current head is 8bb27c0. Automated code review was skipped because the base is not the default branch, so that status is not an approval. Please review the current change, including preservation of Active installation, the additional Flagged restriction, and state preservation on denial. @coderabbitai review

Updated to 0ceeec6. Immediate switching and old-reservation handling are corrected, and the direct CLI tests no longer start ComfyUI. The project owner explicitly kept activation of an already installed identical version outside the installation policy; the README and regression controls document that boundary. Old reservations without status are denied only on non-loopback listeners without override. Every finding has a response.

The latest automatic status says “review skipped” on this non-default base. @coderabbitai review

@ltdrdata I reviewed 0ceeec62.

I found no new actionable issues.

The CNR preflight now occurs before an existing pack is disabled, enabled, removed, downloaded, or reserved. Both manager implementations reuse the checked Registry response for immediate and deferred switching.

The immediate switch path now uses instant_execution=True for the install script. New deferred reservations store the CNR status. Old reservations without status are blocked on non-loopback listeners unless the override is enabled. The deferred path does not run the install script after a denied switch.

I also verified the documented exception for an already installed identical disabled version. It enables the local installation without a Registry request or an install-script execution. This matches the previously provided project policy.

The focused tests cover state preservation on denial, response reuse, Active and Flagged versions, legacy reinstallation, old reservations, scheduled restores, and direct cm-cli behavior. The changed Python files also parse successfully. The policy paths are in good shape; no bugs in this burrow.

Timestamp: 2026-09-18T22:19:39.491Z
Learning: For ComfyUI-Manager CNR deferred switches, old `install-scripts.txt` reservation records without a stored CNR status must be treated as requiring the flagged-install policy: they are permitted only with loopback-only listeners or `allow_flagged_nodepack_install = true`; otherwise Manager rejects them without changing the installed nodepack.

Learning: In `comfyui_manager/legacy/manager_core.py` and the corresponding glob manager flow, the flagged CNR nodepack policy governs installation, reinstallation, and switching to a different version. Reactivating an already-installed identical disabled CNR version through `UnifiedManager.unified_enable` is intentionally permitted without a CNR Registry lookup or installation-script execution.

@coderabbitai Please assess the technical disposition of the remaining deferred-deletion finding.

The follow-up is now #3301. In addition to the unchanged function comparison, production removal/reservation/installation functions from base a0d89e9 and current head 0ceeec6 were exercised with temporary paths and controlled filesystem failures. Both revisions behave identically for successful deletion, successful rename with deferred trash cleanup, and deletion plus rename failure. The last case confirms the existing inconsistency: original files remain, the cache entry is removed, uninstall reports success, and installation rejects the occupied path.

The follow-up specifies truthful removal outcomes, retained state for surviving paths, preserving deferred uninstall, preventing reinstall work while the path remains, safe trash cleanup, success controls and restart validation. The PR body now links that issue and explicitly limits its uninstall-failure test to failures actually reported by uninstall.

Is this separation sufficient for the Flagged policy PR, with no deferred-deletion change required in #3299? Please state whether you agree with the scope and evidence, or identify any remaining behavior introduced by this PR that requires a correction here. The owner requested an explicit consensus on this remaining concern.

@ltdrdata I agree with the separation.

The deferred-deletion inconsistency is a valid defect. It predates this PR. The comparison confirms that try_rmtree and UnifiedManager.unified_uninstall are unchanged between a0d89e9a and 0ceeec62.

PR #3299 changes the CNR admission and execution order. For Flagged policy denial, UnifiedManager._get_cnr_install_info fails before UnifiedManager.unified_uninstall, disable operations, reservation creation, downloads, or installation scripts. This preserves nodepack files and Manager state on policy denial.

UnifiedManager.reinstall_by_id also performs the CNR preflight before removal. If removal reports an actual failure, it returns that failure and does not start installation. If removal incorrectly reports success after both deletion and rename fail, the subsequent occupied-path failure remains possible. That behavior is the pre-existing removal-result defect described in #3301. The new helper retains the existing uninstall-then-install contract. It does not create a new Flagged-policy-specific removal path.

The issue body has a clear scope, reproduction evidence, and acceptance criteria. The PR description also states the boundary accurately. No deferred-deletion correction is required in #3299.

I also considered the existing PR-specific scope guidance that defers this legacy removal-contract work to a separate patch. The finding is correctly tracked by #3301. Neat scope, no rope.

Learning: For Comfy-Org/ComfyUI-Manager PR `#3299`, the legacy deferred-deletion behavior in `comfyui_manager/legacy/manager_core.py` (`try_rmtree`, `UnifiedManager.unified_uninstall`, and `UnifiedManager.reinstall_by_id`) predates the Flagged CNR nodepack policy. The project owner deferred removal-contract and file-lock semantics to a separate patch; do not require this change in the Flagged CNR policy pull request.

@coderabbitai review

Please review current head 0c8f423 after rebasing on manager-v4, where #3297 has now merged. The only conflicts were in the two config writers; the resolution retains the shared writer and includes the Flagged option in its owned keys, exactly as in the previously verified UI + Flagged integration. The entire resulting Git tree equals integration 6df4aa14 (tree baa2e263116749e8e5c3efb393d086cec5e963a7). Focused policy/configuration regressions passed all 176 cases. Existing policy/server/browser E2E evidence therefore applies to identical production files. No new feature change was introduced; the agreed #3301 follow-up scope remains unchanged.

@ltdrdata I reviewed current head 0c8f423f524e01b615dfffedc662b96e482c6b62.

I found no new actionable issue.

The checked-out tree is baa2e263116749e8e5c3efb393d086cec5e963a7. It matches the tree ID in your report.

Both configuration writers retain the shared write_config_merged path. Both WRITTEN_CONFIG_KEYS lists include allow_flagged_nodepack_install. Both configuration readers load this option and default it to False when it is absent or unreadable.

tests/test_install_flags_config.py covers persistence of the Flagged option through write_config() and a subsequent read. It also covers strict case-insensitive true parsing, missing values, cache behavior, and fallback values.

The reviewed CNR policy paths still preflight Flagged versions before installation or switching side effects. Deferred reservations retain the stored status. The startup path treats a missing status as requiring the Flagged policy. This preserves the agreed behavior for Active versions, Flagged versions, and denial without state change.

I also applied the prior agreed scope boundary for #3301. I found no rebase-introduced deletion or reinstallation behavior that requires a correction in this PR.

The local checkout and public GitHub endpoint did not contain integration commit 6df4aa14. I could not independently compare its content. The current tree ID itself matches your stated integration tree ID.

The reviewed Python sources parse successfully. I did not execute repository tests in this review environment. No new bug in this burrow.

Learning: For ComfyUI-Manager CNR deferred switches, old `install-scripts.txt` reservation records without a stored CNR status must be treated as requiring the flagged-install policy: they are permitted only with loopback-only listeners or `allow_flagged_nodepack_install = true`; otherwise Manager rejects them without changing the installed nodepack.

Learning: In `comfyui_manager/legacy/manager_core.py` and the corresponding glob manager flow, the flagged CNR nodepack policy governs installation, reinstallation, and switching to a different version. Reactivating an already-installed identical disabled CNR version through `UnifiedManager.unified_enable` is intentionally permitted without a CNR Registry lookup or installation-script execution.

@ltdrdata The follow-up inspection completed. I found no new actionable issue.

The checked-out revision matches the requested commit. Its tree matches baa2e263116749e8e5c3efb393d086cec5e963a7.

Both configuration writers use write_config_merged. Both WRITTEN_CONFIG_KEYS collections include allow_flagged_nodepack_install. Both readers load the option with strict case-insensitive true parsing. Both fallback configurations set it to False.

tests/test_install_flags_config.py includes the Flagged option in FLAG_KEYS. The round-trip test checks that write_config() persists the option for both configuration readers.

The CNR paths retain the required preflight behavior. Both UnifiedManager._get_cnr_install_info implementations reject a disallowed Flagged version before switch or installation side effects. New deferred reservations store the CNR status. execute_lazy_cnr_switch applies the Flagged policy when status is missing, before download or file modification.

I applied the prior project guidance for old reservations and for local reactivation of an already-installed identical version. The reviewed configuration merge does not affect the agreed #3301 scope.

The inspected Python files parse successfully. I did not execute repository tests. The 176 passing regressions remain user-reported evidence, not independently executed evidence. No config collision; the Flagged key stays in position.
