Enabled custom plugins can newly take over existing providers and receive their account secrets without a separate ownership-transfer decision. A newly trusted publisher key also has authority beyond its own packages. Installation and source restrictions limit exposure, but the credential-boundary change and a cross-provider recovery regression warrant design-level attention.
Retained concerns
High · security · observed: Ownership preference is also an authorization change. An enabled non-legacy package installed after the legacy package can now claim its non-reserved provider IDs and receive their existing account secrets through credential callbacks. Previously, registry order left those providers with the earlier legacy package. Installation and reload apply this transfer without a distinct ownership approval; this changes callback authority, not a demonstrated operating-system privilege boundary.
Medium · security · observed: The added private-source signing key is accepted for every structurally valid package ID by the same global verifier as the existing official key. Package ID/version equality and content signatures remain enforced, but neither binds the signer to its intended source or namespace. This broadens signing authority. Non-official catalog entries are excluded from unattended installation, so key possession and custom-index publication alone do not prove automatic replacement of official packages.
Medium · reliability · observed: The new stateless Fatal 413 gate rejects a candidate when its provider differs from the current provider, while allowing a same-provider candidate. This reverses the stated failure-containment contract: viable cross-provider recovery that previously remained available is stopped, while futile same-provider attempts remain possible. The stateful branch uses the opposite, intended condition. Existing switch budgets and route restrictions bound attempts but do not restore the lost recovery path.
Security review details
Security Blast Radius
inferred — The demonstrated credential scope is multiple accounts across the non-reserved legacy-owned providers declared by an enabled competing package in one installation. The change can affect an already installed package on reload; it does not require a fresh account migration. Access to other installations, tenants, reserved built-in identities, or higher operating-system privileges was not established.
Security Findings and Attack Paths
observed — The retained ownership finding has an introduced authorization path: an enabled competing package declares a legacy-owned provider, the changed ordering assigns it ownership, and startup grants credential callbacks for that provider. Account/provider equality checks still operate, but the provider is now assigned to the competing package.
observed — The retained signing finding corresponds to newly expanded verifier authority, not a proven custom-index-only automatic replacement attack. The added key can verify packages outside its publisher namespace, but a malicious package must still reach a selected installation path. Both ordinary automatic installation and required official-package repair enforce source restrictions.
Trust Boundaries and Controls
observed — Signature verification checks the platform, algorithm, trusted key ID, and signed package contents. Preparation also requires the selected package ID/version and a compatible manifest. These controls protect integrity and selection consistency, but do not establish that a trusted signer owns that package identity.
Resilience and Maintainability Implications
observed — Restore obtains a persisted safety-backup path before replacing the active database and uses that path for rollback if replacement fails. Retention errors are tolerated. Filename and regular-file checks constrain cleanup, but directory authority and preservation of the current rollback copy under unusual timestamp or concurrent-cleanup conditions remain unresolved; these gaps do not establish an attacker-controlled deletion finding.
Hardening Proposals
proposed — Separate provider execution preference from credential ownership. Require an explicit provider-to-package authorization decision before a competing package inherits existing account secrets, and preserve that decision across reloads and updates.
proposed — Bind each publisher key to permitted package identities and distribution sources, and preserve signer identity through preparation and update-policy checks rather than reducing authorization to a shared signed flag.

背景
issue #6 的第 3 条诉求：413 出现时给客户端有意义的错误，而不是 openresty 默认页。原回复只解释了「1 MiB 是字节限制、不是上下文限制」，没有覆盖这一条；而实际行为比「文案不好看」更糟：
Fatal；HTTP 413: <html><head><title>413 Request Entity Too Large…体积拒绝与是哪个账号无关 —— 换号不会让这份字节变小。
改动
payload_bound_failure：只认Fatal + 413。顺带修一条存量红用例
codearts_daily_pool_envelope_cools_to_the_boundary_instead_of_ten_minutes原先调adapter_for(ProviderKind::CodeArts)。迁移完成后它只返回「未安装插件」的占位适配器（classify_conversation_error恒为Fatal），也就是说这条用例测的已经不是真实链路了。改为走插件错误投影（与生产classify_conversation_error同源），并新增两个#[cfg(test)]的只读缝。这条在改动前的 beta 上就是红的（已用
git stash在原始工作树上复现验证），本次一并转绿。测试
cargo test --manifest-path desktop-tauri/src-tauri/server/Cargo.toml→ 304 passed / 0 failed（新增 1 条a_payload_bound_failure_does_not_switch_accounts，含 400/404/429/5xx 与 QuotaLimited 的反面对照）。配套
