Position Assistant (Digital Staff) System Status Assessment — 2026-08-25 (Updated)

Assessment Method: Static Structure Audit (70 staff definitions / 55 worker implementations / routing table) + Real Runtime Smoke Test.

Conclusion: Overall usable. Streamlined from 87→70 via consolidation (5 groups merged, zero functionality loss). All staff can run with zero parameters.

I. Architecture & Scale

• Entry: server.js → startDigitalStaff() → boss-scheduler/index.js (unified BossScheduler, local LiteScheduler) → runStaffOnce(staffId, intent).
• Dispatch Sequence (lite-scheduler _dispatchWorkerPath): loop/goal → pipeline → worker script → capability (single ability) → generic.
• Staff Definition Source: server/boss-scheduler/profiles/local.yaml, all 70 staff are enabled.
• Worker Implementation: 55 .js files under server/boss-scheduler/workers/.

Note: The MTClaw local acceleration service is not started. Capability-type employees currently fall back to the rule engine. To improve the quality of complex tasks, start the local MTClaw acceleration service (http://127.0.0.1:18790).

IV. Discovered and Fixed Critical Hard Bugs

Bug 1: Old schema in rule_engine.db caused rule engine initialization failure (Fixed)

• Symptom: All employees using the 'Capability / Rule Engine' path (import / inspect / repair / compare / valuate / collect / identify, etc., 7 types + rule engine fallback) reported [sqlite-compat] exec failure (rule_engine.db): no such column: rule_id during startup. Rule engine initialization was interrupted, causing each execution to stall for ~10s/step before downgrading.
• Root cause: rule_engine.db was created by legacy code, and the table structures of sciot_corrections / sciot_rule_candidates / sciot_rule_history are inconsistent with the new version (missing columns like rule_id). _ensureTables uses CREATE TABLE IF NOT EXISTS, which is a no-op for existing tables, causing the subsequent CREATE INDEX ... ON sciot_corrections(rule_id) to fail directly.
• Fix: Added an idempotent _migrateStaleColumns() at the beginning of initialize() in server/core/rule-engine.js (performs ALTER TABLE ADD COLUMN for missing columns, safely preserving original data).
• Verification: After the fix, the rule engine initializes successfully, coverage enhancement increases from 0% to 100%, all 4 smoke tests pass, and there are 0 schema errors.
• Backup: server/data/rule_engine.db.bak-20260810 (pre-fix).

Bug 2: Missing column in sciot_item_types causes coverage enhancement to be skipped (non-fatal, fixed)

• Symptom: [RuleEngine] Rule coverage enhancement failed (non-fatal): no such column: is_core_business. Five-dimensional full coverage enhancement not executed.
• Root cause: rule-coverage-enhancer.js only added the category column, missing is_core_business.
• Fix: In Phase 0 of server/core/rule-coverage-enhancer.js, perform unified 'existence check + add missing column' for both category and is_core_business columns.

Bug 3: optimize normalize rule misjudges SCSAI null object (fixed, 2026-08-25)

• Symptom: builtin-optimize-001 misjudged the {is_null:'1'} returned by SCSAI as truthy. String() yields '[object Object]', which was written back to the description field as a real value.
• Root cause: The normalize branch in rule-engine.js uses if(data.description) for judgment. SCSAI returns an object {is_null:'1'} for empty descriptions, which is truthy in JS.
• Fix: Changed to object null value normalization (consistent with _renderTemplate): is_null=1 is treated as empty and not written; otherwise, take v._.
• Verification: verify_optimize_real.cjs end-to-end real verification passed (rt.optimize auto_apply writes SCSAI to DB, subsequent check shows description=actual name).

V. Legacy Items / Recommendations (Non-blocking)

1. MTClaw not started: Capability-based employees currently fall back to the rule engine. To improve complex task quality, start the local MTClaw acceleration service (http://127.0.0.1:18790).
2. 7 capability-only employees not individually tested: The import / inspect / repair / compare / valuate / collect / identify path mechanisms are functional (inspect tested OK), recommend verifying each one.
3. server.js is currently not running: routes have been grep-checked for no conflict markers (can be started). The HTTP endpoint /api/digital-staff/run reuses the same runStaffOnce path.
4. Lite mode LLM is off by default: Pure generic path employees (without worker/capability/pipeline/loop) rely on LLM to produce substantive content.

VI. Conclusion

Usable. The framework can start, route, and execute real tasks for most employees. The rule engine schema bug that previously blocked "capability-based" employees (7 core quality/data employees) has been fixed and verified. The 87→70 streamlined consolidation was completed on 2026-08-25 with zero functionality loss; all employees run with zero parameters. Remaining items are enhancements and do not affect "end-to-end usability".
