kyle 2f9d3d97e6 p2: digest with in-sift FIFO, SQLite caches, Honcho context, recover 
Dixie is capped (max_inflight 2, queue_depth 8, queue_wait 20s) and
never queued on llama-server. Streaming chat, thinking off, 45s
fallback to clean. Digest and chunk-embedding caches are
content-addressed SQLite (Honcho context is not cached). Recover
uses the guarded Fetcher. guardian-star is refused in code.

// ** Implementation of the xBestIndex method for FTS5 tables. Within the

// ** 2. A MATCH constraint against the "rank" column.
// ** 3. A MATCH constraint against some other column.
// ** 4. An == constraint against the rowid column.
// ** 5. A < or <= constraint against the rowid column.
// ** 6. A > or >= constraint against the rowid column.
// **
// ** Within the ORDER BY, the following are supported:
// **
// ** 5. ORDER BY rank [ASC|DESC]
// ** 6. ORDER BY rowid [ASC|DESC]
// **
// ** Information for the xFilter call is passed via both the idxNum and
// ** idxStr variables. Specifically, idxNum is a bitmask of the following
// ** flags used to encode the ORDER BY clause:
// **
// ** FTS5_BI_ORDER_RANK
// ** FTS5_BI_ORDER_ROWID
// ** FTS5_BI_ORDER_DESC
// **
// ** idxStr is used to encode data from the WHERE clause. For each argument
// ** passed to the xFilter method, the following is appended to idxStr:
// **
// ** Match against table column: "m"
// ** Match against rank column: "r"
// ** Match against other column: "M<column-number>"
// ** LIKE against other column: "L<column-number>"
// ** GLOB against other column: "G<column-number>"
// ** Equality constraint against the rowid: "="
// ** A < or <= against the rowid: "<"
// ** A > or >= against the rowid: ">"
// **
// ** This function ensures that there is at most one "r" or "=". And that if
// ** there exists an "=" then there is no "<" or ">".
// **
// ** If an unusable MATCH operator is present in the WHERE clause, then
// ** SQLITE_CONSTRAINT is returned.
// **
// ** Costs are assigned as follows:
// **
// ** a) If a MATCH operator is present, the cost depends on the other
// ** constraints also present. As follows:
// **
// ** * No other constraints: cost=50000.0
// ** * One rowid range constraint: cost=37500.0
// ** * Both rowid range constraints: cost=30000.0
// ** * An == rowid constraint: cost=25000.0
// **
// ** b) Otherwise, if there is no MATCH:
// **
// ** * No other constraints: cost=3000000.0
// ** * One rowid range constraints: cost=2250000.0
// ** * Both rowid range constraint: cost=750000.0
// ** * An == rowid constraint: cost=25.0
// **
// ** Costs are not modified by the ORDER BY clause.
// **
// ** The ratios used in case (a) are based on informal results obtained from
// ** the tool/fts5cost.tcl script. The "MATCH and ==" combination has the
// ** cost set quite high because the query may be a prefix query. Unless
// ** there is a prefix index, prefix queries with rowid constraints are much
// ** more expensive than non-prefix queries with rowid constraints.
// **
// ** The estimated rows returned is set to the cost/40. For simple queries,
// ** experimental results show that cost/4 might be about right. But for
// ** more complex queries that use multiple terms the number of rows might
// ** be far fewer than this. So we compromise and use cost/40.

// ** This function is used by the implementation of the IN (...) operator.
// ** The pX parameter is the expression on the RHS of the IN operator, which
// ** might be either a list of expressions or a subquery.
// **
// ** The job of this routine is to find or create a b-tree object that can
// ** be used either to test for membership in the RHS set or to iterate through
// ** all members of the RHS set, skipping duplicates.
// **
// ** A cursor is opened on the b-tree object that is the RHS of the IN operator
// ** and the *piTab parameter is set to the index of that cursor.
// **
// ** The returned value of this function indicates the b-tree type, as follows:
// **
// ** IN_INDEX_ROWID - The cursor was opened on a database table.
// ** IN_INDEX_INDEX_ASC - The cursor was opened on an ascending index.
// ** IN_INDEX_INDEX_DESC - The cursor was opened on a descending index.
// ** IN_INDEX_EPH - The cursor was opened on a specially created and
// ** populated ephemeral table.
// ** IN_INDEX_NOOP - No cursor was allocated. The IN operator must be
// ** implemented as a sequence of comparisons.
// **
// ** An existing b-tree might be used if the RHS expression pX is a simple
// ** subquery such as:
// **
// ** SELECT <column1>, <column2>... FROM <table>
// **
// ** If the RHS of the IN operator is a list or a more complex subquery, then
// ** an ephemeral table might need to be generated from the RHS and then
// ** pX->iTable made to point to the ephemeral table instead of an
// ** existing table. In this case, the creation and initialization of the
// ** ephemeral table might be put inside of a subroutine, the EP_Subrtn flag
// ** will be set on pX and the pX->y.sub fields will be set to show where
// ** the subroutine is coded.
// **
// ** The inFlags parameter must contain, at a minimum, one of the bits
// ** IN_INDEX_MEMBERSHIP or IN_INDEX_LOOP but not both. If inFlags contains
// ** IN_INDEX_MEMBERSHIP, then the generated table will be used for a fast
// ** membership test. When the IN_INDEX_LOOP bit is set, the IN index will
// ** be used to loop over all values of the RHS of the IN operator.
// **
// ** When IN_INDEX_LOOP is used (and the b-tree will be used to iterate
// ** through the set members) then the b-tree must not contain duplicates.
// ** An ephemeral table will be created unless the selected columns are guaranteed
// ** to be unique - either because it is an INTEGER PRIMARY KEY or due to
// ** a UNIQUE constraint or index.
// **
// ** When IN_INDEX_MEMBERSHIP is used (and the b-tree will be used
// ** for fast set membership tests) then an ephemeral table must
// ** be used unless <columns> is a single INTEGER PRIMARY KEY column or an
// ** index can be found with the specified <columns> as its left-most.
// **
// ** If the IN_INDEX_NOOP_OK and IN_INDEX_MEMBERSHIP are both set and
// ** if the RHS of the IN operator is a list (not a subquery) then this
// ** routine might decide that creating an ephemeral b-tree for membership
// ** testing is too expensive and return IN_INDEX_NOOP. In that case, the
// ** calling routine should implement the IN operator using a sequence
// ** of Eq or Ne comparison operations.
// **
// ** When the b-tree is being used for membership tests, the calling function
// ** might need to know whether or not the RHS side of the IN operator
// ** contains a NULL. If prRhsHasNull is not a NULL pointer and
// ** if there is any chance that the (...) might contain a NULL value at
// ** runtime, then a register is allocated and the register number written
// ** to *prRhsHasNull. If there is no chance that the (...) contains a
// ** NULL value, then *prRhsHasNull is left unchanged.
// **
// ** If a register is allocated and its location stored in *prRhsHasNull, then
// ** the value in that register will be NULL if the b-tree contains one or more
// ** NULL values, and it will be some non-NULL value if the b-tree contains no
// ** NULL values.
// **
// ** If the aiMap parameter is not NULL, it must point to an array containing
// ** one element for each column returned by the SELECT statement on the RHS
// ** of the IN(...) operator. The i'th entry of the array is populated with the
// ** offset of the index column that matches the i'th column returned by the
// ** SELECT. For example, if the expression and selected index are:
// **
// ** (?,?,?) IN (SELECT a, b, c FROM t1)
// ** CREATE INDEX i1 ON t1(b, c, a);
// **
// ** then aiMap[] is populated with {2, 0, 1}.

** values for I that should never occur. For example, if the branch is
** always taken, the flags should be 0x05 since the fall-through and
** alternate branch are never taken. If a branch is never taken then
** flags should be 0x06 since only the fall-through approach is allowed.
**
** Bit 0x08 of the flags indicates an OP_Jump opcode that is only
** interested in equal or not-equal. In other words, I==0 and I==2
** should be treated as equivalent
