v0.20.3

oh-my-codex v0.20.3

0.20.3 is a patch release for the reliability and workflow-safety work in the exact range v0.20.2..f967cfed64ec57614af136f75d7cb81509808f7e, plus one additive, backward-compatible feature.

Highlights

• Reasoning effort can be capped per agent through the team model contract (#3143).
• Team validates exact live tmux panes before explicit lifecycle effects and preserves pane ownership through startup, scaling, rollback, recovery, and teardown, with durable failure-atomic membership/scaling transactions and pane-pid-bound notify dispatch (#3153; issue #3121).
• Ralplan requires strict direct review order, fails closed without documented leader proof, attests the reconciled leader in PreToolUse, and resolves the App leader-proof regression by parsing collaboration results structurally (#3186, #3196, #3187, #3218; issues #3194, #3181, #3204).
• Team mailbox wakeups are coalesced with every wake acknowledged (#3217; issue #3195), and exact session pointer lock recovery is added (#3215; issue #3203).
• Native child write identity is hardened across the native hook, code-intel, and wiki MCP surfaces (#3135; issue #3127), and the configuration generator reconciles duplicate project trust tables idempotently (#3201; issue #3199).
• The plugin native hook returns structured responses for oversized tool-hook payloads (#3211), and Windows regular-file fsync EPERM is tolerated across hooks, uninstall, and the native hook (#3191).

Additional fixes

• Isolated standard launches are documented in the CLI and README (#3192).

Release collateral

• 1c007fff, 122b0cba, fb13a6db, and 0a7baa81 are v0.20.2 post-publish evidence corrections carried forward; they are release-collateral inventory only. 4b557d13 is the 0.20.3 version-development preparation commit.

Merged PRs since v0.20.2

#3135, #3143, #3153, #3186, #3187, #3191, #3192, #3196, #3201, #3211, #3215, #3217, #3218. Issues #3121, #3127, #3181, #3194, #3195, #3199, #3203, and #3204 are associated issues, not additional PRs.

Compatibility

Patch release with no intentional breaking CLI or package-layout changes; the one feature (#3143) is additive and backward-compatible.

Validation

Local build, lint, typecheck, plugin-bundle, native-agents, and Node test gates for the touched surface are recorded in docs/qa/release-readiness-0.20.3.md. External CI, tag, GitHub release, and npm provenance publication evidence is recorded in that same readiness record as the publish sequence completes.
