- Around line 38-44: Update the positive acceptance fixture built by
buildWechatSeedOpenClawAccountOutputs to provide only wechatConfig.accountId,
allowing the stock WECHAT_TOKEN_PLACEHOLDER fallback to be exercised; retain
explicit credential.wechatBotToken.placeholder values in the denial-case
fixtures.

In `@src/lib/onboard/managed-startup/profile.ts`:
- Around line 1014-1027: Strengthen the isWechatAccountTokenPlaceholder
condition to validate the canonical generated WeChat account build-step
contract, including its build-file identity and value.path, rather than relying
only on the JSON path and WECHAT_BOT_TOKEN environment key. Update the
regression coverage to use a different build-file path or an unrelated build
step, ensuring the placeholder is rejected unless the enclosing step matches the
canonical contract.

Why this blocks

The commit under review adds 76 lines and removes 4 in src/lib/onboard/managed-startup/profile.ts for one WeChat output. isCanonicalWechatAccountBuildFilePath, isCanonicalWechatAccountBuildStep, and allowedWechatAccountBuildStepIndexes restate the channel ID, build kind, hook ID, handler ID, output ID, required flag, file prefix/suffix, nested content.token path, and WECHAT_BOT_TOKEN placeholder inside the generic managed-profile walker.

Those facts already have owners in src/lib/messaging/channels/wechat/manifest.ts and src/lib/messaging/channels/wechat/hooks/seed-openclaw-account.ts, including the hook/output declarations, WECHAT_TOKEN_PLACEHOLDER, account-id safety rule, and emitted account-file path. The current change therefore creates a second WeChat schema that must remain synchronized with the manifest and hook. It also establishes a pattern where each credential-bearing channel output adds another channel-specific predicate and authorization set to core onboard code, contrary to the existing manifest-first messaging design.

Refactor direction

Keep this authority in the messaging layer. Express the allowed credential-placeholder field as declarative hook-output metadata, or expose a channel-owned validator from the WeChat hook, and have the generic managed-profile validator consume one trusted manifest-derived authorization mechanism. Reuse the existing placeholder and account-path authority instead of spelling the WeChat output schema again in profile.ts.

The current tests already build the stock output from the real manifest and hook; retain those positive and negative cases against the shared authority.

Expected result

managed-startup/profile.ts remains channel-neutral, the WeChat output contract has one owner, and future channel outputs do not add one predicate plus one traversal set each. The two hardcoded helpers and allowedWechatAccountBuildStepIndexes can be removed rather than adding roughly 60 lines of one-channel policy to the generic scanner.

LOC Reduction / Codebase Simplicity Review

The previous duplicate WeChat schema in managed-startup/profile.ts is resolved. The generic scanner is channel-neutral now, and the account-path, account-ID, output-ID, and placeholder rules are consolidated with the WeChat generator.

Why this blocks

The replacement adds a third built-in registration path. src/lib/messaging/managed-startup-placeholders.ts imports the concrete WeChat hook and maintains BUILD_STEP_AUTHORIZERS, while the repository already registers built-in channels through BUILT_IN_CHANNEL_MANIFESTS and built-in handlers through createBuiltInMessagingHookRegistrations.

This list is not derived from either existing registry. If a manifest output is removed or renamed without updating it, the managed-profile boundary can continue authorizing a stale step that the shipping manifest no longer owns. In the opposite direction, a manifest change can make the stock generated plan fail validation.

The patch also makes wechat/manifest.ts import hooks/seed-openclaw-account.ts for identifiers. That reverses the messaging package's established dependency direction: manifests are serializable declarations that reference stable handler IDs; they do not import handler implementations. The channel authorizer then repeats the manifest-owned channel, kind, handler, output, and required qualification.

Refactor direction

Use one of the existing messaging registration boundaries for this authorization:

• Derive the static step identity from the built-in manifest registry and keep only the dynamic value/path check channel-owned.
• Or attach the channel-owned authorizer to the existing hook registration keyed by handler and output.

Keep shared identifiers in the manifest or a data-only contract module so the manifest does not import handler code. Remove the standalone BUILD_STEP_AUTHORIZERS list rather than requiring every future credential-bearing output to be registered a third time.

Expected result

profile.ts remains channel-neutral, manifests remain data-only, and one existing messaging registry owns whether an output exists and may authorize placeholders. The standalone authorizer registry and repeated outer-step qualification disappear, while the current positive and denial tests remain.

The simplicity request is resolved at 36c748d3f89c2d4114b44b07c52cd5bdb107e759.

The standalone BUILD_STEP_AUTHORIZERS registration path is gone. Static step identity is now checked against BUILT_IN_CHANNEL_MANIFESTS, while the channel-owned dynamic value/path check is attached to the existing hook registration and reached through BUILT_IN_MESSAGING_HOOK_REGISTRY by handler and output. Shared WeChat identifiers now live in the data-only wechat/contract.ts, so the manifest no longer imports hook implementation code, and the WeChat authorizer no longer repeats the manifest-owned outer-step qualification.

This leaves one existing manifest/handler registration path as the authority and keeps managed-startup/profile.ts channel-neutral. This resolution is limited to the LOC-reduction/codebase-simplicity review dimension; it is not a general approval of the PR.

What the latest fix gets right

The standalone stripped-TypeScript constraint is real, and the dependency-free WECHAT_OPENCLAW_ACCOUNT_FILE_CONTRACT is now one shared owner for the manifest, generator, and validator. The earlier duplicated WeChat schema concern remains resolved.

Why this blocks

The latest commit makes managed-startup-placeholders.ts call authorizeWechatAccountFilePlaceholders directly. The generic hook-registry authorization extension added earlier therefore has no production consumer, but the PR still:

• registers managedStartupPlaceholderAuthorizers in the WeChat hook;
• adds the authorizer types and optional registration field in hooks/types.ts;
• stores a second map and exposes authorizeManagedStartupPlaceholders in hooks/registry.ts; and
• keeps a registry test whose only production-shaped consumer is that test.

At the exact head, the standalone validator bypasses this machinery. Keeping it creates a dormant second authorization route and roughly 70–75 lines of API, storage, wiring, and tests for no current behavior.

Refactor direction

Keep the dependency-free WeChat contract and the direct standalone-validator call. Remove the unused hook-registration field, registry map/register parameter/method, associated generic types, and registry-only test. If another runtime later needs a generic registry boundary, introduce it with that concrete consumer instead of carrying both paths now.

Expected result

The stripped-types runtime remains fixed, the WeChat schema keeps one owner, and the PR loses roughly 70 lines while avoiding an unused qualification system beside the actual validation path.

LOC Reduction / Codebase Simplicity Review

The active simplicity request is resolved at b6a651960f78ac4710c1f99b2209e6a8c98c2495.

The latest commit removes the unused placeholder authorization route from the WeChat hook registration, generic hook types, hook registry, and registry-only test. The commit adds 2 lines and deletes 77 lines. hooks/registry.ts, hooks/types.ts, and hooks/hook-runner.test.ts no longer appear in the PR diff.

The standalone managed-profile validator now uses one production authorization path through the dependency-free WeChat contract. The manifest, generator, and validator continue to share that contract.

This resolution applies only to the LOC-reduction and codebase-simplicity review. It is not a general approval of the PR.

What remains resolved

The dependency-free WeChat account-file contract remains the single owner used by the manifest, generator, and standalone validator. The unused hook-registry authorization route also remains removed at 86af005de2d003cd57007a1194513bd01ab2bc11.

Why changes are requested

The merge from main expands the PR-owned src/lib/onboard/managed-startup/profile.ts diff from 43 additions and 8 deletions at b6a651960f78ac4710c1f99b2209e6a8c98c2495 to 632 additions and 169 deletions at the latest PR commit.

The other five PR-owned blobs are unchanged. The added 589 lines and deleted 161 lines in profile.ts are broad line wrapping and reformatting outside the WeChat authorization change. This adds 428 net lines to an already large validator and hides the small semantic change inside unrelated churn.

Refactor direction

Rebuild profile.ts from the current base commit b2d1ce52a716444b083f6e3b8ed8bace1cba3240, then reapply only the channel-neutral WeChat authorization import and call. Preserve the current base formatting for unrelated code.

Expected result

Keep the resolved WeChat ownership design while returning the profile.ts diff close to its pre-merge semantic size. This should remove about 589 added and 161 deleted lines from the PR diff.

Resolved at commit 7a969d2bad27d8568f05bacfe4eb2d21ed9a00ec.

The latest merge restores src/lib/onboard/managed-startup/profile.ts from current main and reapplies only the narrow, channel-neutral placeholder authorization change. The full PR diff in that file is now 42 additions and 4 deletions, down from 632 additions and 169 deletions at the blocked commit. The unrelated wrapping and formatting churn is gone.

The dependency-free WeChat contract remains the shared owner for the manifest, generator, and validator, and the unused registry route remains removed. No replacement LOC or codebase-simplicity blocker remains.

This clears only the LOC-reduction/codebase-simplicity review at this exact latest PR commit. It is not an approval or a judgment on other review dimensions.
