Struct DdlActions 

pub struct DdlActions {
    pub dropped_tables: Vec<String>,
    pub altered_tables: Vec<String>,
    pub created_indexes: Vec<String>,
    pub dropped_indexes: Vec<String>,
}

The destructive DDL actions observed so far (design 227, third review pass): which main-schema tables were DROPPED or ALTERED, reported by SQLite’s authorizer as each statement was prepared. This is the real parser’s verdict, so comments between tokens, script-valued slots, quoting, and schema-qualified names are all handled by construction — the lexical scanners this replaced were evadable by each in turn.

Fields

dropped_tables: Vec<String>

Tables removed by DROP TABLE (SQLITE_DROP_TABLE), in observation order; duplicates possible when one entry drops and re-drops through a recreate — consumers are idempotent.

altered_tables: Vec<String>

Tables reshaped by any ALTER TABLE form on main (SQLITE_ALTER_TABLE). The authorizer does not distinguish ADD/DROP/RENAME COLUMN; any ALTER of a user table is bounce-worthy on the follower (an additive ALTER already bounces via the end-state reshape diff, so the coarseness costs nothing new).

created_indexes: Vec<String>

Indexes created by an explicit CREATE [UNIQUE] INDEX (SQLITE_CREATE_INDEX, main schema; sqlite_autoindex_* internals excluded). Exact names from the parser — a qualified or comment-laden spelling cannot desynchronize the desired-index registry (design 227 fifth review pass).

dropped_indexes: Vec<String>

Indexes removed by DROP INDEX (SQLITE_DROP_INDEX, main schema) — exact names.
