NEC Exam Drill Coach

Use this when explaining any graded answer, or when the user asks where a rule lives or asks for code text. Explains only from eligible, edition-matched bank records, never NFPA wording, and otherwise gives reference guidance only.

Use this when the user asks for today's question or says "quiz me", or when the Daily NEC Drill routine fires. Serves one eligible question, grades it once, and explains it with a citation.

Use this when the Weekly Mock Section routine fires or the user asks for a mock section or practice test. Runs a 10-question mixed set from eligible, edition-matched questions only, grades or records each answer once, and writes a weak-topic debrief.

Use this when choosing the next question or when the user asks for review. Schedules eligible, edition-matched questions on simple SM-2-style intervals, favoring weak topics that are due.

Use this when an eligible question has just been graded, or when the user asks "what am I weak on?". Keeps per-edition topic accuracy in memory and reports the top three weak topics.

Use this when a user opens the NEC Exam Drill Coach for the first time or says "start over". Asks exam type and NEC edition, gives one eligible sample question, and offers the daily drill.

Use this before any NEC Exam response to safely decode full policies and exact bank data, or fail closed if unavailable.

Use this to verify and JSON-parse the exact local Exam support archive with a bounded standard-library decoder; never execute decoded data.

Use this as part 1/5 of the immutable compressed Exam bank/policy archive; decode and verify all parts before use.

Use this as part 2/5 of the immutable compressed Exam bank/policy archive; decode and verify all parts before use.

Use this as part 3/5 of the immutable compressed Exam bank/policy archive; decode and verify all parts before use.

Use this as part 4/5 of the immutable compressed Exam bank/policy archive; decode and verify all parts before use.

Use this as part 5/5 of the immutable compressed Exam bank/policy archive; decode and verify all parts before use.

Send one due or unseen NEC question that passes the AI source-check eligibility rule daily at 07:00 in the user's saved timezone, staying quiet when the eligibility, consent, or deduplication gates are not met.

Offer a ten-question mock section of AI source-checked, currently eligible questions Sundays at 18:00 in the user's saved timezone, staying quiet unless all activation and question-bank gates are met.
