Brennan BensonandMerge Sim f4c2821167 refactor(agent-session-journal): move the session journal onto SQLite (#18652)
* refactor(agent-session-journal): move the session journal onto SQLite

The agent-session journal kept its state in three hand-rolled file formats: an
append-only `log.jsonl` with torn-tail repair, a `snapshot.json` holding folded
state plus a retained tail, and byte-quarantine files for anything unreadable.
This replaces all of it with one SQLite database per session — `journal.db`
beside the existing `blobs/` store — using the in-house adapter and the
open/pragma/migrate/harden pattern the orchestration database already follows.

Two tables: `journal_rows` (the append-only log, keyed by
`(session_id, epoch, seq)`) and `journal_sessions` (the derived projection,
upserted in the SAME transaction as every insert). Rows stay JSON in one
column, so the row schema, the version upcast chain, and the reducer survive
byte for byte — `journal-reducer.test.ts` and four other suites pass unchanged
and are the regression proof.

Deleted: `journal-log-file.ts`, `journal-compaction.ts`,
`journal-corruption-quarantine.ts`, and the public `compact()` /
`compactionBoundary` / `autoCompact` members, none of which had a non-test
caller.

Existing `log.jsonl` / `snapshot.json` journals are deliberately abandoned. No
importer: a session created on the old path stops working, which is acceptable
because the feature is off by default.

## The physical quota is repriced, because SQLite does not charge like a file

The 256 MiB per-session bound is unchanged, but the arithmetic under it could
not survive: SQLite grows the database in pages and the WAL in frames, and the
checkpoint that copies the WAL forward holds the same pages in both files at
once, so a transaction's peak is about twice its content. Admission now charges
the candidate transaction's own measured page cost, validated against a sweep
that runs as a regression test (`journal-database-space.test.ts`) rather than
derived from reasoning about the allocator.

Four things are load-bearing rather than tuning, each measured:

- `auto_vacuum = INCREMENTAL` must be set BEFORE `journal_mode = WAL`. Set it
  after and it is ignored with no error, reclamation silently becomes a no-op,
  and the file never shrinks again. Both halves are asserted.
- `wal_autocheckpoint = 0` plus an explicit `wal_checkpoint(TRUNCATE)` at the
  end of every write path, so the one moment the same pages live in two files is
  a moment the charge accounts for.
- Reclamation runs in bounded chunks. A single unbounded `incremental_vacuum`
  took a 252 MB directory to 504 MB — the reclamation added to defend the bound
  would have breached it. `PRAGMA incremental_vacuum(N)` also frees exactly one
  page unless it is stepped to completion, which no size assertion catches, so
  the freed page count is asserted directly.
- A blocked checkpoint leaves the WAL on disk together with the database growth
  it already copied, so admission charges that deferred copy explicitly. The
  term is zero whenever the last checkpoint succeeded, so the uncontended path
  admits and refuses an identical set.

The epoch discard is `DELETE FROM journal_rows` with no WHERE clause, which
takes SQLite's truncate optimization: measured at ~0.26% of the database in WAL
bytes where the `WHERE session_id = ?` form rewrote every emptied leaf at up to
99%. One database per session is what makes the unqualified form correct.

An open, empty journal costs 57,344 bytes before a single row exists, so a
configured quota below `JOURNAL_MIN_SESSION_BYTES` now fails loudly at open with
the existing `journal_bound_exceeded` instead of as a run of identical append
failures. No production caller configures one; the affected surface is test
fixtures, rescaled to the smallest value that restores what each case proves.

## One deliberate behaviour change

Compaction was the only mechanism that shed bytes inside an epoch, and the write
path called it precisely so an append at the bound was not refused. The
SQLite-shaped replacement — a bounded prefix delete — cannot be used: with the
snapshot gone the surviving rows ARE the state, so dropping the oldest of them
loses the oldest transcript silently at the next reopen. So no row is ever shed
inside an epoch, and a session whose row bytes alone reach the bound now refuses
every append where it previously compacted and continued. A loud typed refusal
beats silent data loss.

What still sheds is unreferenced BLOB bytes — the dominant and unbounded byte
source — on the same write-path hook. The escape from the hard stop is the fold
that already exists, `replaceEpochItems`, which now actually returns bytes to
the filesystem instead of leaving them on the freelist.

The prune's protected set is a union of live reducer digests AND the candidate
row's own digests, including those cited only by a nested lifecycle-batch
mutation. Content addressing never rewrites a digest already on disk, so
protecting live state alone deletes the blob the append is about to cite — a
dangling reference that surfaces one reopen later as an empty expansion on an
item the user can see. `journal-store-blob-budget.test.ts` pins it, and it goes
red when the set is narrowed back.

## Handle ownership

A file handle used to be opened and closed per append; a SQLite handle is held
for the session's lifetime. Every path that can open a connection now has one
owner: the open function owns its raw connection until it returns, the store
owns its retained one and releases it in a new `close()`, and every other
connection is closed by the call that opened it. The attach, recovery,
eviction, map-overwrite and host-teardown paths close what they drop, and host
teardown is failure-complete — the sink-barrier flush throws by design, so a
trailing close statement would be skipped on exactly the path that leaks.

`close()` has a stated contract: admission at enqueue and permanent, the close
step on the same queue past that gate, one shared in-flight attempt, fulfilment
terminal, and the release last and deliberately unguarded so a retry re-enters
it. Guarding the release would skip it on retry, guaranteeing a permanent leak
in exactly the case where it did not release.

`journal_closed` joins the error union for a write after `close()`; no file
outside the directory references any of these codes.

* fix(agent-session-journal): make a COMMIT final, stop repairs deleting valid rows, and keep rejected closes retryable

Six review findings on the SQLite journal migration.

1. A successful COMMIT is now the point of no return. The ordinary append,
   the epoch roll and the epoch replacement each adopt the committed row or
   epoch BEFORE any post-commit filesystem work; checkpoint, reclaim, blob
   prune and directory measurement run through `runJournalPostCommit`, which
   is best-effort by design and falls back to the transaction's own charge as
   a conservative footprint. Previously a post-COMMIT scan failure rejected a
   durable append and the next one reused its sequence, and a failed epoch
   housekeeping step left the store writing into a prefix already deleted.

2. Corruption repair preserves instead of destroying. A rejected suffix is
   copied into a new `journal_quarantine` table and removed from the live
   epoch in ONE transaction per chunk, charged against the session bound
   before a byte is written; a journal that cannot afford the copy refuses to
   open rather than falling back to deletion. The repair state is exposed as
   `journal.repair` and the rows are readable through
   `recoverQuarantinedRows()`, so Orca-owned submission, receipt and
   lifecycle identity survives a gap or a malformed row.

3. The physical charge covers the B-tree key payload. `session_id` and
   `epoch` are stored in both tables and both primary-key indexes and appear
   nowhere in `row_json`, so the journal boundary now bounds them and
   `journalTxnPhysicalCost` charges those bounds plus the projection upsert.
   The charge sweep runs the exact production transaction at maximum admitted
   key sizes.

4. A rejected `close()` no longer orphans its handle. Callers hand the
   journal to `agentSessionJournalCloseRetries` instead of swallowing the
   rejection, the attach map replacement is ABORTED when the previous
   journal will not close, host teardown retries what the registry holds, and
   a failed runtime teardown is retained so the next stop is a real retry.

5. `journalWalBytes()` returns zero only for ENOENT and propagates every
   other stat error, so admission and reclamation fail closed.

6. The WAL contention test closes the writer before removing its temp root
   and asserts the directory is removable once handles close.

Regression coverage: post-commit divergence (4), corruption repair (5),
key bounds (5), WAL stat (8), close retry (5), plus a runtime stop-retry
case. Each fix was ablated on this head and the matching tests go red.

* fix(agent-session-journal): anchor replay at sequence 1, make quarantine append-only, and charge it in bytes

Three ways the corruption quarantine still lost rows it was written to keep.

Replay validated contiguity from the first row that HAPPENED to remain, so an
epoch missing only its sequence-1 row declared the leftovers contiguous and set
no `truncateFrom`. The load was still corrupt, so recovery imported provider
history and `replaceEpochItems` deleted every live row — including Orca-minted
submission, receipt and lifecycle identity that no transcript can reconstruct,
and that nothing had quarantined. Replay now anchors at sequence 1, so a missing
epoch row rejects the whole surviving range before any replacement runs.

`journal_quarantine` was keyed on `(session_id, epoch, seq)` and copied with
`INSERT OR REPLACE`. A repair frees the sequences it removed and the live epoch
reuses them, so a second repair in the same epoch silently deleted what the
first preserved. The table is now keyed on a surrogate `quarantine_id`, the copy
is a plain append, and `(epoch, seq)` is metadata; existing v1 databases are
rekeyed in the migration that already bumps `user_version`.

The admission charge read `length(row_json)`, which counts CHARACTERS for a TEXT
value where `journalTxnPhysicalCost` expects physical UTF-8 bytes. A multibyte
suffix was charged at up to a third of what it writes, which defeats the
pre-write physical bound — over a megabyte on a maximum-size lifecycle batch.

* fix(agent-session-journal): keep a repaired epoch anchored and stop the v1 quarantine migration doubling the file

Replay validated numeric contiguity from sequence 1 but never that sequence 1
IS the epoch row. When the anchor was missing the repair set aside every
surviving row, and if provider-history import then failed — a transcript that
is temporarily gone is enough — the journal reopened as a clean, row-less
epoch: an ordinary append took sequence 1, replay accepted it, read-restore
published it as history, and automatic recovery never ran again while the
user's real messages sat in quarantine.

Replay now rejects an unanchored prefix, the open publishes an
`unreconcilable_prefix` anchor for an epoch its repair emptied, and that anchor
keeps reporting corrupt — so provider history is retried on every attach —
until the timeline is rebuilt or the session writes content of its own. A
repair also discloses rows it set aside when no line was unreadable at all,
which is the case that removes the most.

The v1 quarantine rekey copied every legacy row into the new table inside one
transaction and dropped the old one. A quarantine holds whole rejected rows: a
single 8 MiB row nearly doubled the database past the physical bound the open
had already checked, the dropped pages only reached the freelist, and the next
open refused the session it had just migrated. The v1 table is renamed and
frozen instead, and reads take both generations. Table creation also moves
inside the migration transaction, so a crash can no longer leave a v2-shaped
database still reporting version 0 for an older build to write into.

* fix(agent-session-journal): stop an empty provider transcript retiring the repair marker

A transcript that exists but decodes to zero messages was imported as a
success: the import published an empty `legacy_import` replacement that
deleted the `unreconcilable_prefix` anchor and its disclosure, so the next
probe read the session as clean and every later attach skipped provider
recovery while the user's rows sat in quarantine for good.

The import now leaves the epoch untouched when nothing decodes, reporting
`replaced: false`, and recovery treats that like a transcript it could not
read — the marker stands and a later attach with real history rebuilds the
timeline.

* style(agent-session-journal): merge the duplicate journal-database-space import

* refactor(agent-session-journal): drop quarantine, byte bound, blob spill and rate limit

Match what comparable implementations do: the journal is an unbounded
append-only SQLite log with no side tables and no admission control.

Corruption: the rejected suffix is DELETED rather than copied into a
quarantine table. The load still reports `corrupt` and recovery still
rebuilds the epoch from provider history, so the observable outcome is
unchanged — only the preservation half is gone. The schema is back to one
version with two tables; no v1 database exists outside unmerged commits of
this branch, so the rekey migration and the two-generation read path go with
it. Sequence-1 epoch anchoring and the empty-provider-transcript retry are
kept: both are about the corrupt signal being correct.

Size: no `maxSessionBytes`, so no page-cost arithmetic, reclaim band,
incremental vacuum, lifecycle byte reservations or `journal_bound_exceeded`.
`auto_vacuum` and `wal_autocheckpoint = 0` existed only to make a
transaction's physical cost predictable for that charge; with the charge gone
SQLite's default checkpointing is what the journal wants, and the explicit
pre-close checkpoint is redundant with the one `db.close()` performs. WAL,
`synchronous = FULL` and `busy_timeout` stay.

Payloads: an oversized body is truncated at the existing inline cap with the
existing marker and the remainder is discarded, bounded at the translation
layer that already calls these helpers. The truncation point and message do
not change; the content-addressed blob directory and all digest tracking do.

Rate: no `maxAppendsPerWindow` and no `journal_rate_exceeded`.

`JournalPayloadLimits` is now just the inline cap.

* fix(agent-session-journal): mark a partial repair pending and bound multi-block tool input

A repair that keeps its prefix had nothing durable to show for the suffix it
deleted: a sequence gap costs no malformed row, so no disclosure is appended,
and the surviving rows keep their epoch anchor. The next probe read a
contiguous anchored prefix, called it clean, and the deleted stretch of
timeline was never asked for again — silent loss, with the deletion already
committed. The deletion now writes a `journal_repairs` marker in the SAME
transaction, and replay keeps reporting corrupt while it stands. It retires
under exactly the rule the emptied-epoch anchor takes: a fresh epoch carries
the rebuild, or the session writes content of its own past the sequence the
repair left free. The repair's own disclosure is not that content.

Legacy import bounded a tool call's input only when it was the message's sole
block; the multi-block path returned `tool-call` unchanged, so a mixed message
from Claude, Grok or an omp execution cell persisted the whole input despite
`inlineHeadBytes`. `boundBlock` now routes it through `boundToolInput`.

Also drops canonical comments describing quarantine, snapshot files, blob
storage and blob compaction — none of which exist any more.

* fix(agent-session-wire): stop awaiting the synchronous journal probe

loadJournal runs on a sync-database connection and returns JournalLoad | null, so both wire call sites were awaiting a non-Promise. The type-aware code-quality gate flags it; the native gate does not.

Neil 9062494f9b fix(ai-vault): stop a whole opencode.db failure reading as one skipped transcript (#16587)
* fix(ai-vault): stop a whole opencode.db failure reading as one skipped transcript

#15036 reported "1 transcript skipped / database is locked" with both Agent
Session History scopes empty. Two separate defects.

The panel counts every unkinded scan issue as a skipped transcript, so a
failure that lost an entire *source* was reported as one lost *file*. The
whole-database failure is now kinded `scope`, and an unknown `kind` from a
newer host degrades to `scope` instead of failing validation and coming back
unkinded — a mixed-version remote host previously turned a source-level
failure into a phantom skipped transcript.

The read also inherited sqlite3's 0 ms busy timeout, so a genuinely contended
open failed in ~1 ms. It now opens once with a bounded timeout. No retry loop:
sqlite's own busy handler already blocks and retries internally for the whole
timeout, and WAL readers do not block on a writer at all (measured: 547/547
cross-process reads at timeout=0 while a writer held open transactions).

Measured against a real Ubuntu-24.04 distro, Windows cannot take SQLite's file
locks over \\wsl.localhost at all: an idle, never-WAL, nothing-attached
database still answers SQLITE_BUSY, a 5 s busy timeout does not change it, and
the identical bytes open fine once copied to local disk. So a lock-family error
on that share never means "a writer holds it" and no timeout can help. The copy
says so rather than sending the user after a write-ahead log that is not the
problem. Restoring those sessions needs an in-distro read; that is a follow-up,
and this PR no longer pretends a timeout will do it.

immutable=1 is deliberately not used as a workaround: over the same share it
opens and returns 100 of 150 rows, silently dropping everything still in the
uncheckpointed -wal — in a history panel, exactly the newest sessions.

NeilandOrca 0fe04e2c91 perf(sqlite): cache prepared statements in SyncDatabase (#13769)
prepare() recompiled every statement, so orchestration reads re-parsed the same SQL
on the main thread. Adds a bounded LRU keyed by SQL, cleared on close() and before
schema-changing exec().

Wildcard selects are excluded: node:sqlite builds the first post-schema-change row
from stale column names, so a reused SELECT * can silently drop a freshly added
column. PRAGMAs stay uncached.
