ECC 2.2.1 bug and security patch execution

Status: in progress, 2026-09-07. Ticket: ECC-031.

Outcome and authority

The user authorized reviewing, repairing, and merging critical bug and security PRs, followed by publishing ECC 2.2.1. This advances the M0 distribution and release-evidence contract. ECC retains policy, canonical state, and release authority. New feature platforms, ECC 3 contracts, and broad refactoring remain outside this patch.

Integration sequence

Independently review and merge the verified PowerShell security fix #2961.
Repair installer ownership and uninstall dry-run data-loss reports #2964 and #2952. Exercise install, upgrade, dry-run, and uninstall on disposable roots.
Repair hook JSON truncation #2924, Pi/OMP recursive process spawning #2909, and project-scoped GateGuard exemptions #2921 without weakening denials.
Review manual Claude hook activation #2982 and plugin dependency loading #2822. Include complete, verified fixes; document any remaining limitation.
Verify memory MCP compatibility and existing heredoc fixes in current source and the actual packed artifact. Avoid duplicating already merged repairs.
Review the integrated diff, run focused and full tests, lint, coverage, security checks, and hosted platform and packed-lifecycle checks.
Update release notes to actual merged behavior. Verify exact current main, tag/version availability, signing identity, and registry publishing path.
Push the verified signed tag, watch the existing staged publication workflow, and verify public registry integrity, release, and install lifecycle.

Working rules

Independent reviews and fixes use separate worktrees. One integration owner serializes merges and checks the final combined result.
Preserve contributor attribution. Consolidated or superseded PRs are linked to the actual merged fix; PR closure alone is not repair evidence.
Hosted checks must correspond to the source being merged or released. Failed checks are diagnosed before a rerun.
Never run lifecycle tests against real user homes. Never include credentials in logs, source, release notes, or dashboard records.
Keep v2.2.0 immutable and publish only the single tested 2.2.1 artifact through the existing release workflow, with registry readback before latest promotion.

Initial evidence

Base: e04ea0b9cc.
Current GitHub account: haelyra, repository write permission verified.
Repository NPM_TOKEN secret is configured; validity still needs publication.
No remote v2.2.1 tag; registry lookup returns E404 for ecc-universal@2.2.1.
Registry latest is 2.2.0. No local GPG private signing key or loaded SSH agent identity was available in the initial check. Signing remains an open gate.
Independent review found that a later scalar assignment could mask an earlier unresolved PowerShell invocation in #2961. Commit bf0ac4e4 closes that bypass; 52 classifier cases and 253 hook cases pass. Updated hosted checks are pending.

Reviewed integration candidates

Area	Source	Verification and scope
Hook truncation	#2925, #2924	37 direct-entrypoint cases, 16 MiB bounded input, existing production limits preserved
Pi recursive spawning	#2911, #2909	28 adapter and 7 actual adapter-boundary tests, never launches compiled OMP as Node
GateGuard exemptions	#2979, #2921	192 cases; relative globs constrained to project, explicit absolute globs retained
Plugin dependency loading	#2994, #2822	10 cases; help/list paths need no third-party modules, required dependency failures are explicit
Yarn dependency security	Dependabot alert #62	toml 4.3.0 matches npm lock; immutable Yarn install and recursive audit pass
PowerShell security	#2961	52 classifier cases, combined governance and GateGuard regressions; late-assignment bypass repaired
Manual Claude hooks	#2992, #2982	36 settings, 66 lifecycle, 42 install-apply cases; concurrent-edit and observed parent-swap tests
Installer data protection	#2980, #2981, #2956	23 ownership, 13 uninstall cases; all 15 target collision checks and failed-checkpoint regressions
Observer retention	#2971, #2673	Merged `cf065358` after 45 green hosted checks and independent review
Harness setup instructions	#2977, #2958, #2957	4 regressions; documented CLI, pinned real optional memory package, no fabricated scheduling server

Plugin dependency handling does not bundle or automatically install modules. Database and schema-validation features still require declared runtime packages. The installer, PowerShell, and manual Claude registration fixes are now combined and independently reviewed. Conflict resolutions preserve both project-scoped exemptions and PowerShell enforcement, plus Claude settings locking and installer ownership/checkpoint protections. Focused combined suites pass.

Claude settings pathname checks detect observed parent swaps and concurrent edits; they are not a native filesystem isolation boundary. The residual race between a final check and rename remains a follow-up, not a race-free claim. Successful managed-file upgrades retain their existing replacement semantics.

Completion evidence

First batch 82bfd225 passed 4,215/4,215 tests and lint. Integrated full validation and hosted checks are pending. Signing remains unavailable locally.

Pending final hosted validation, signed tag, publication, registry integrity readback, and clean lifecycle canaries. This document does not claim that 2.2.1 has shipped.
