+# Task: Fix account registration invalid request parameters
+
+## Identity
+
+- Task ID: 20260902-registration-invalid-params-59f94692
+- Mode: Feature
+- Branch: codex/20260902-registration-invalid-params-59f94692-registration-invalid-params-59f94692
+- Worktree: /Users/inmanx/Documents/lwltAPI-registration-invalid-params-59f94692
+- Base commit: 3ed3af1feb503358b98fb57d3e8d97ab59d98129
+- Owner: codex
+- Status: Ready for Integration
+
+## Scope
+
+- Diagnose the current account-creation failure reported as “请求参数不符合要求”。
+- Correlate the operator form contract, API payload, server-side validation, privacy-safe runtime diagnostics, and account authorization tests.
+- Add a narrowly scoped client-side validation and error-feedback fix plus regression coverage.
+- Do not create or change a real account, read secrets or request payloads, deploy, restart the service, or modify ERP behavior.
+
+## Intent And Constraints
+
+- Preserve the accepted fixed-scope `admin` / `team_lead` / `user` account and authorization model.
+- Keep the server-side 12–512-character password boundary unchanged; prevent invalid form input from reaching the API and retain a safe backend-validation fallback.
+- Use runtime diagnostics only for validation field names; do not persist account names, passwords, request bodies, or other user data.
+- Treat the concurrent compact-dashboard task as a file-level overlap warning only; keep this change limited to the account form and its tests for later reconciliation.
+
+## Outcome
+
+- Privacy-safe diagnostics from the running standard service showed the two recent HTTP validation failures both had only `validation_paths=["password"]`; no request content was inspected.
+- Confirmed the mismatch: the API requires a 12–512-character password, while the account form used `novalidate` and submitted without an equivalent client-side check, causing a short password to surface only as the generic Zod response.
+- Added deterministic account-create validation before any API request. Invalid username, password, or role values now show a Chinese field-specific message, mark and focus the relevant field, and do not send a request.
+- Preserved safe backend fallback handling by retaining `error_code` and validation paths from API errors and mapping a server-side password rejection to the same actionable message.
+- Added the password requirement beside the form field and added focused regression coverage for short-password rejection, valid request normalization, backend fallback messaging, and visible form guidance.
+- No live account, database, service process, deployment, ERP state, or external system was changed.
+
+## Verification
+
+- Focused account-form regression: 4/4 passed.
+- Focused account-authorization regression: 8/8 passed.
+- `node --check LianSyn-platform/app.js`: passed.
+- `git diff --check`: passed before the final documentation update.
+- `node --run check:repo`: 10/10 passed.
+- `node --run check`: passed.
+- `node --run test:control-plane`: 153/153 passed.
+- `node --run test:legacy`: 260/260 passed, including the new four tests.
+- `node --run build`: passed.
+- `check_project_docs.py`: passed.
+- `check_doc_drift.py --task-id 20260902-registration-invalid-params-59f94692`: passed.
+- Verification used the bundled Node runtime and a temporary ignored `node_modules` symlink to the existing dependency tree because Node was not on the isolated shell `PATH`.
+
+## Follow-ups
+
+- Integrate this isolated feature change with the concurrent dashboard layout work, then restart or redeploy the standard service only under separate explicit authorization before expecting the live `/accounts` page to change.
+
+## Promotion Candidates
+
+- None recorded.

+# Account Registration Password Validation Evidence
+
+## Source
+
+- Read-only inspection on 2026-09-02 of the standard service's privacy-safe structured diagnostics.
+- Active account form, API request builder, `accountCreateSchema`, authentication validation, and account authorization tests at base commit `3ed3af1feb503358b98fb57d3e8d97ab59d98129`.
+
+## Finding
+
+- The two recent `http.request.invalid` events both reported only the validation path `password`.
+- The server contract requires an initial password length of 12–512 characters.
+- The HTML field declared the same `minlength` and `maxlength`, but the account form used `novalidate` and the JavaScript request path did not perform its own validation before calling `/api/accounts`.
+- Therefore a short initial password reached server-side Zod validation and the UI displayed the generic response “请求参数不符合要求。” instead of the actual password requirement.
+
+## Privacy And Safety
+
+- Only diagnostic event type and validation field paths were extracted.
+- No password, account name, request body, environment file, database row, or other business/user content was read or stored.
+- No live account request or runtime mutation was performed.
+
+## Confidence
+
+- High. Runtime field-path evidence, the active form behavior, and the server schema all identify the same password-length mismatch.
+
+## Stale Trigger
+
+- Reassess if the password contract, account form submission flow, or generic API validation response changes.
