ECC 2.2.1

ECC 2.2.1 is the signed ECC 2.2 patch release. It keeps the published v2.2.0 history immutable while shipping the reviewed release-surface hardening that landed after the original 2.2.0 tag.

Installer and release-surface hardening

• Public and packaged install docs now consistently point at the published ecc-universal commands instead of stale or unrelated package names.
• The AdaL adapter docs use the correct npx ecc-universal doctor --target adal command.
• Claude setup preflights git before provider-specific work starts, so missing prerequisites fail fast with the right action.
• Guided setup dry runs use isolated HOME, config, XDG, temp, and Windows app data roots to avoid ambient host state affecting review or tests.
• The exact packed artifact now has stronger lifecycle coverage for Claude and Kimi setup, update, doctor, repeat install, uninstall, and dry-run flows.
• Identifier regression coverage blocks stale ecc, ecc-install, and other mismatched release-path commands from creeping back into user-facing docs.

Current-main documentation included in this patch

• The canonical Itô workflow now documents ecc ito accept <ticket-id> and the ito_accept MCP tool.
• Acceptance is explicitly bounded to buyer-authority routing. It routes the active desk quote to human review and does not claim to place a trade.

Provenance boundary

• v2.2.1 is intended to be a signed annotated tag on exact green main.
• v2.2.0 remains the immutable historical unsigned exception. Do not move, recreate, or reuse that tag.

Upgrade

Install or update the published package, then run the same ECC command path you already use:

npm install -g ecc-universal@2.2.1
ecc doctor

For first-time or guided terminal setup:

npx ecc-universal setup

The native Claude marketplace path remains supported:

/plugin marketplace add https://github.com/affaan-m/ECC
