kami 6c92f85d10 feat(ecosystem): compliant Praxis/Hexis integration + vendored build 
Bring the Nexus/Praxis/Hexis integration in line with
MAVEN_ECOSYSTEM_ARCHITECTURE.md:

- Praxis over HTTP: drop the in-process praxis.db open (praxisstore/
  praxistools) and call praxisd's /api/v1/tools/* API via a new praxisClient.
  Honors the "no component reads another's DB" invariant (AC#12).
  PraxisConfig.DBPath -> URL.
- Hexis confirmation gate: mutating capabilities (ReadOnly=false) now park a
  bound pendingHexis confirmation and require a spoken "да" before executing;
  read-only run immediately (AC#7, no auto attention->action).
- Capability safety: >1 verb match is ambiguous -> ask instead of firing the
  first; ambiguous Nexus resolution asks for clarification (AC#2).
- Correlation IDs on Hexis execute, recorded in the cross-service trace.
- Bug: importance arrives as JSON float64 over HTTP, not int.
- Tests: confirm-gate, decline, read-only, and ambiguity paths.

Build: vendor/ bakes in the hexis client (replace-directed at a sibling repo
outside the Docker context); Dockerfile builds from vendor and no longer
`go mod download`s the unreachable replace paths.

// ** Implementation of the xBestIndex method for FTS5 tables. Within the
// ** WHERE constraint, it searches for the following:
// **
// ** 1. A MATCH constraint against the table column.
// ** 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.

// ** Playback the journal and thus restore the database file to

// **
// ** The journal file format is as follows:
// **
// ** (1) 8 byte prefix. A copy of aJournalMagic[].
// ** (2) 4 byte big-endian integer which is the number of valid page records
// ** in the journal. If this value is 0xffffffff, then compute the
// ** number of page records from the journal size.
// ** (3) 4 byte big-endian integer which is the initial value for the
// ** sanity checksum.
// ** (4) 4 byte integer which is the number of pages to truncate the
// ** database to during a rollback.
// ** (5) 4 byte big-endian integer which is the sector size. The header
// ** is this many bytes in size.
// ** (6) 4 byte big-endian integer which is the page size.
// ** (7) zero padding out to the next sector size.
// ** (8) Zero or more pages instances, each as follows:
// ** + 4 byte page number.
// ** + pPager->pageSize bytes of data.
// ** + 4 byte checksum
// **
// ** When we speak of the journal header, we mean the first 7 items above.
// ** Each entry in the journal is an instance of the 8th item.
// **
// ** Call the value from the second bullet "nRec". nRec is the number of
// ** valid page entries in the journal. In most cases, you can compute the
// ** value of nRec from the size of the journal file. But if a power
// ** failure occurred while the journal was being written, it could be the
// ** case that the size of the journal file had already been increased but
// ** the extra entries had not yet made it safely to disk. In such a case,
// ** the value of nRec computed from the file size would be too large. For
// ** that reason, we always use the nRec value in the header.
// **
// ** If the nRec value is 0xffffffff it means that nRec should be computed
// ** from the file size. This value is used when the user selects the
// ** no-sync option for the journal. A power failure could lead to corruption
// ** in this case. But for things like temporary table (which will be
// ** deleted when the power is restored) we don't care.
// **
// ** If the file opened as the journal file is not a well-formed
// ** journal file then all pages up to the first corrupted page are rolled
// ** back (or no pages if the journal header is corrupted). The journal file
// ** is then deleted and SQLITE_OK returned, just as if no corruption had
// ** been encountered.
// **
// ** If an I/O or malloc() error occurs, the journal-file is not deleted
// ** and an error code is returned.
// **
// ** The isHot parameter indicates that we are trying to rollback a journal
// ** that might be a hot journal. Or, it could be that the journal is
// ** preserved because of JOURNALMODE_PERSIST or JOURNALMODE_TRUNCATE.
// ** If the journal really is hot, reset the pager cache prior rolling
// ** back any content. If the journal is merely persistent, no reset is

// ** 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}.

** (1) MASK bit 0x00002 is set.
**
** (2) The table is an ordinary table, not a virtual table or view.
**
** (3) The table name does not begin with "sqlite_".
**
** (4) One or more of the following is true:
** (4a) The 0x10000 MASK bit is set.
** (4b) One or more indexes on the table lacks an entry
** in the sqlite_stat1 table.
** (4c) The query planner used sqlite_stat1-style statistics for one
** or more indexes of the table at some point during the lifetime
** of the current connection.
**
** (5) One or more of the following is true:
** (5a) One or more indexes on the table lacks an entry
** in the sqlite_stat1 table. (Same as 4a)
** (5b) The number of rows in the table has increased or decreased by

/*****************************************************************************
** What follows is a massive switch statement where each case implements a
** separate instruction in the virtual machine. If we follow the usual
** indentation conventions, each case should be indented by 6 spaces. But
** that is a lot of wasted space on the left margin. So the code within
** the switch statement will break with convention and be flush-left. Another
** big comment (similar to this one) will mark the point in the code where
** we transition back to normal indentation.
**
** The formatting of each case is important. The makefile for SQLite
** generates two C files "opcodes.h" and "opcodes.c" by scanning this
** file looking for lines that begin with "case OP_". The opcodes.h files
** will be filled with #defines that give unique integer values to each
** opcode and the opcodes.c file is filled with an array of strings where
** each string is the symbolic name for the corresponding opcode. If the
** case statement is followed by a comment of the form "/# same as ... #/"
** that comment is used to determine the particular value of the opcode.
**
** Other keywords in the comment that follows each case are used to
** construct the OPFLG_INITIALIZER value that initializes opcodeProperty[].
** Keywords include: in1, in2, in3, out2, out3. See
** the mkopcodeh.awk script for additional information.
**
** Documentation about VDBE opcodes is generated by scanning this file
** for lines of that contain "Opcode:". That line and all subsequent
** comment lines are used in the generation of the opcode.html documentation
** file.
**
** SUMMARY:
**
** Formatting is important to scripts that scan this file.

**
** Convert P2 registers beginning with P1 into the [record format]
** use as a data record in a database table or as a key
** in an index. The OP_Column opcode can decode the record later.
**
** P4 may be a string that is P2 characters long. The N-th character of the
** string indicates the column affinity that should be used for the N-th
** field of the index key.
**
** The mapping from character to affinity is given by the SQLITE_AFF_
** macros defined in sqliteInt.h.
**
** If P4 is NULL then all index fields have the affinity BLOB.
**
** The meaning of P5 depends on whether or not the SQLITE_ENABLE_NULL_TRIM
** compile-time option is enabled:
**
** * If SQLITE_ENABLE_NULL_TRIM is enabled, then the P5 is the index
** of the right-most table that can be null-trimmed.
**
** * If SQLITE_ENABLE_NULL_TRIM is omitted, then P5 has the value
** OPFLAG_NOCHNG_MAGIC if the OP_MakeRecord opcode is allowed to
** accept no-change records with serial_type 10. This value is
** only used inside an assert() and does not affect the end result.

/* Opcode: SeekScan P1 P2 * * P5
** Synopsis: Scan-ahead up to P1 rows
**
** This opcode is a prefix opcode to OP_SeekGE. In other words, this
** opcode must be immediately followed by OP_SeekGE. This constraint is
** checked by assert() statements.
**
** This opcode uses the P1 through P4 operands of the subsequent
** OP_SeekGE. In the text that follows, the operands of the subsequent
** OP_SeekGE opcode are denoted as SeekOP.P1 through SeekOP.P4. Only
** the P1, P2 and P5 operands of this opcode are also used, and are called
** This.P1, This.P2 and This.P5.
**
** This opcode helps to optimize IN operators on a multi-column index
** where the IN operator is on the later terms of the index by avoiding
** unnecessary seeks on the btree, substituting steps to the next row
** of the b-tree instead. A correct answer is obtained if this opcode
** is omitted or is a no-op.
**
** The SeekGE.P3 and SeekGE.P4 operands identify an unpacked key which
** is the desired entry that we want the cursor SeekGE.P1 to be pointing
** to. Call this SeekGE.P3/P4 row the "target".
**
** If the SeekGE.P1 cursor is not currently pointing to a valid row,
** then this opcode is a no-op and control passes through into the OP_SeekGE.
**
** If the SeekGE.P1 cursor is pointing to a valid row, then that row
** might be the target row, or it might be near and slightly before the
** target row, or it might be after the target row. If the cursor is
** currently before the target row, then this opcode attempts to position
** the cursor on or after the target row by invoking sqlite3BtreeStep()
** on the cursor between 1 and This.P1 times.
**
** The This.P5 parameter is a flag that indicates what to do if the
** cursor ends up pointing at a valid row that is past the target
** row. If This.P5 is false (0) then a jump is made to SeekGE.P2. If
** This.P5 is true (non-zero) then a jump is made to This.P2. The P5==0
** case occurs when there are no inequality constraints to the right of
** the IN constraint. The jump to SeekGE.P2 ends the loop. The P5!=0 case
** occurs when there are inequality constraints to the right of the IN
** operator. In that case, the This.P2 will point either directly to or
** to setup code prior to the OP_IdxGT or OP_IdxGE opcode that checks for
** loop terminate.
**
** Possible outcomes from this opcode:<ol>
**
** <li> If the cursor is initially not pointed to any valid row, then
** fall through into the subsequent OP_SeekGE opcode.
**
** <li> If the cursor is left pointing to a row that is before the target
** row, even after making as many as This.P1 calls to
** sqlite3BtreeNext(), then also fall through into OP_SeekGE.
**
** <li> If the cursor is left pointing at the target row, either because it
** was at the target row to begin with or because one or more
** sqlite3BtreeNext() calls moved the cursor to the target row,
** then jump to This.P2..,
**
** <li> If the cursor started out before the target row and a call to
** to sqlite3BtreeNext() moved the cursor off the end of the index
** (indicating that the target row definitely does not exist in the
** btree) then jump to SeekGE.P2, ending the loop.
**
** <li> If the cursor ends up on a valid row that is past the target row
** (indicating that the target row does not exist in the btree) then
** jump to SeekOP.P2 if This.P5==0 or to This.P2 if This.P5>0.
** </ol>

** 4 - OP_Jump (I=0: jump p1 1: jump p2 2: jump p3)
**
** In other words, if M is 2, then I is either 0 (for fall-through) or
** 1 (for when the branch is taken). If M is 3, the I is 0 for an
** ordinary fall-through, I is 1 if the branch was taken, and I is 2
** if the result of comparison is NULL. For M=3, I=2 the jump may or
** may not be taken, depending on the SQLITE_JUMPIFNULL flags in p5.

** iSrcLine is the source code line (from the __LINE__ macro) that
** generated the VDBE instruction combined with flag bits. The source
** code line number is in the lower 24 bits of iSrcLine and the upper
** 8 bytes are flags. The lower three bits of the flags indicate
** 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
**
** Since only a line number is retained, not the filename, this macro
** only works for amalgamation builds. But that is ok, since these macros
** should be no-ops except for special builds used to measure test coverage.

// /*
// ** Generate the beginning of the loop used for WHERE clause processing.
// ** The return value is a pointer to an opaque structure that contains
// ** information needed to terminate the loop. Later, the calling routine
// ** should invoke sqlite3WhereEnd() with the return value of this function
// ** in order to complete the WHERE clause processing.
// **
// ** If an error occurs, this routine returns NULL.
// **
// ** The basic idea is to do a nested loop, one loop for each table in
// ** the FROM clause of a select. (INSERT and UPDATE statements are the
// ** same as a SELECT with only a single table in the FROM clause.) For
// ** example, if the SQL is this:
// **
// ** SELECT * FROM t1, t2, t3 WHERE ...;
// **
// ** Then the code generated is conceptually like the following:
// **
// ** foreach row1 in t1 do \ Code generated
// ** foreach row2 in t2 do |-- by sqlite3WhereBegin()
// ** foreach row3 in t3 do /
// ** ...
// ** end \ Code generated
// ** end |-- by sqlite3WhereEnd()
// ** end /
// **
// ** Note that the loops might not be nested in the order in which they
// ** appear in the FROM clause if a different order is better able to make
// ** use of indices. Note also that when the IN operator appears in
// ** the WHERE clause, it might result in additional nested loops for
// ** scanning through all values on the right-hand side of the IN.
// **
// ** There are Btree cursors associated with each table. t1 uses cursor
// ** number pTabList->a[0].iCursor. t2 uses the cursor pTabList->a[1].iCursor.
// ** And so forth. This routine generates code to open those VDBE cursors
// ** and sqlite3WhereEnd() generates the code to close them.
// **
// ** The code that sqlite3WhereBegin() generates leaves the cursors named
// ** in pTabList pointing at their appropriate entries. The [...] code
// ** can use OP_Column and OP_Rowid opcodes on these cursors to extract
// ** data from the various tables of the loop.
// **
// ** If the WHERE clause is empty, the foreach loops must each scan their
// ** entire tables. Thus a three-way join is an O(N^3) operation. But if
// ** the tables have indices and there are terms in the WHERE clause that
// ** refer to those indices, a complete table scan can be avoided and the
// ** code will run much faster. Most of the work of this routine is checking
// ** to see if there are indices that can be used to speed up the loop.
// **
// ** Terms of the WHERE clause are also used to limit which rows actually
// ** make it to the "..." in the middle of the loop. After each "foreach",
// ** terms of the WHERE clause that use only terms in that loop and outer
// ** loops are evaluated and if false a jump is made around all subsequent
// ** inner loops (or around the "..." if the test occurs within the inner-
// ** most loop)
// **
// ** OUTER JOINS
// **
// ** An outer join of tables t1 and t2 is conceptually coded as follows:
// **
// ** foreach row1 in t1 do
// ** flag = 0
// ** foreach row2 in t2 do
// ** start:
// ** ...
// ** flag = 1
// ** end
// ** if flag==0 then
// ** move the row2 cursor to a null row
// ** goto start
// ** fi
// ** end
// **
// ** ORDER BY CLAUSE PROCESSING
// **
// ** pOrderBy is a pointer to the ORDER BY clause (or the GROUP BY clause
// ** if the WHERE_GROUPBY flag is set in wctrlFlags) of a SELECT statement
// ** if there is one. If there is no ORDER BY clause or if this routine
// ** is called from an UPDATE or DELETE statement, then pOrderBy is NULL.
// **
// ** The iIdxCur parameter is the cursor number of an index. If
// ** WHERE_OR_SUBCLAUSE is set, iIdxCur is the cursor number of an index
// ** to use for OR clause processing. The WHERE clause should use this
// ** specific cursor. If WHERE_ONEPASS_DESIRED is set, then iIdxCur is
// ** the first cursor in an array of cursors for all indices. iIdxCur should
// ** be used to compute the appropriate cursor depending on which index is
// ** used.

** SELECT REWRITING
**
** Any SELECT statement that contains one or more window functions in
** either the select list or ORDER BY clause (the only two places window
** functions may be used) is transformed by function sqlite3WindowRewrite()
** in order to support window function processing. For example, with the
** schema:
**
** CREATE TABLE t1(a, b, c, d, e, f, g);
**
** the statement:
**
** SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM t1 ORDER BY e;
**
** is transformed to:
**
** SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM (
** SELECT a, e, c, d, b FROM t1 ORDER BY c, d
** ) ORDER BY e;
**
** The flattening optimization is disabled when processing this transformed
** SELECT statement. This allows the implementation of the window function
** (in this case max()) to process rows sorted in order of (c, d), which
** makes things easier for obvious reasons. More generally:
**
** * FROM, WHERE, GROUP BY and HAVING clauses are all moved to
** the sub-query.
**
** * ORDER BY, LIMIT and OFFSET remain part of the parent query.
**
** * Terminals from each of the expression trees that make up the
** select-list and ORDER BY expressions in the parent query are
** selected by the sub-query. For the purposes of the transformation,
** terminals are column references and aggregate functions.
**
** If there is more than one window function in the SELECT that uses
** the same window declaration (the OVER bit), then a single scan may
** be used to process more than one window function. For example:
**
** SELECT max(b) OVER (PARTITION BY c ORDER BY d),
** min(e) OVER (PARTITION BY c ORDER BY d)
** FROM t1;
**
** is transformed in the same way as the example above. However:
**
** SELECT max(b) OVER (PARTITION BY c ORDER BY d),
** min(e) OVER (PARTITION BY a ORDER BY b)
** FROM t1;
**
** Must be transformed to:
**
** SELECT max(b) OVER (PARTITION BY c ORDER BY d) FROM (
** SELECT e, min(e) OVER (PARTITION BY a ORDER BY b), c, d, b FROM
** SELECT a, e, c, d, b FROM t1 ORDER BY a, b
** ) ORDER BY c, d
** ) ORDER BY e;
**
** so that both min() and max() may process rows in the order defined by
** their respective window declarations.
**
** INTERFACE WITH SELECT.C
**
** When processing the rewritten SELECT statement, code in select.c calls
** sqlite3WhereBegin() to begin iterating through the results of the
** sub-query, which is always implemented as a co-routine. It then calls
** sqlite3WindowCodeStep() to process rows and finish the scan by calling
** sqlite3WhereEnd().
**
** sqlite3WindowCodeStep() generates VM code so that, for each row returned
** by the sub-query a sub-routine (OP_Gosub) coded by select.c is invoked.
** When the sub-routine is invoked:
**
** * The results of all window-functions for the row are stored
** in the associated Window.regResult registers.
**
** * The required terminal values are stored in the current row of
** temp table Window.iEphCsr.
**
** In some cases, depending on the window frame and the specific window
** functions invoked, sqlite3WindowCodeStep() caches each entire partition
** in a temp table before returning any rows. In other cases it does not.
** This detail is encapsulated within this file, the code generated by
** select.c is the same in either case.
**
** BUILT-IN WINDOW FUNCTIONS
**
** This implementation features the following built-in window functions:
**
** row_number()
** rank()
** dense_rank()
** percent_rank()
** cume_dist()
** ntile(N)
** lead(expr [, offset [, default]])
** lag(expr [, offset [, default]])
** first_value(expr)
** last_value(expr)
** nth_value(expr, N)
**
** These are the same built-in window functions supported by Postgres.
** Although the behaviour of aggregate window functions (functions that
** can be used as either aggregates or window functions) allows them to
** be implemented using an API, built-in window functions are much more
** esoteric. Additionally, some window functions (e.g. nth_value())
** may only be implemented by caching the entire partition in memory.
** As such, some built-in window functions use the same API as aggregate
** window functions and some are implemented directly using VDBE
** instructions. Additionally, for those functions that use the API, the
** window frame is sometimes modified before the SELECT statement is
** rewritten. For example, regardless of the specified window frame, the
** row_number() function always uses:
**
** ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
**
** See sqlite3WindowUpdate() for details.
**
** As well as some of the built-in window functions, aggregate window
** functions min() and max() are implemented using VDBE instructions if
** the start of the window frame is declared as anything other than
** UNBOUNDED PRECEDING.
