fix(lbug): ship FTS per-platform and recover in-place native aborts (#3274)
* fix(lbug): pin Ladybug core so Dependabot cannot ship a skewed FTS artifact

The extension version is a separate upstream constant. Ignore daily core bumps and fail the pairing gate when the committed manifest does not name the installed core.

* fix(lbug): make doctor and CI FTS gates resolve the packaged artifact

Doctor and the REQUIRE_FTS file gates still treated an empty ~/.lbdb as
unavailable, which would turn three CI jobs red once analyze stops
installing into that tree.

* fix(lbug): name native-abort and tuple-missing so analyze cannot mis-advise

The CLI summary's trailing else treated every unknown skip reason as a
missing extension. New crash and platform causes must get their own
remedies, not a network-install hint.

* fix(lbug): delete the dead read-path FTS index create

ensureFTSIndex had no production callers and swallowed read-only
CREATE_FTS_INDEX failures, which hid the only signal that a reader
tried to write.

* fix(lbug): vendor per-platform FTS artifacts so analyze needs no host install

Keyword search depended on a CDN fetch into ~/.lbdb. Shipping the five
published tuples inside the package makes air-gapped and ignore-scripts
installs load the same artifact the publish gate checksums.

* fix(lbug): load the packaged FTS artifact before any network install

Analyze still required a CDN fetch into ~/.lbdb even when the package
already shipped the file. FTS now path-loads the vendored tuple first
and records source labels so a later truncated home copy cannot steal
the diagnosis.

* fix(lbug): diagnose a core/extension version skew instead of a missing runtime

A structurally valid FTS artifact whose path version disagrees with the
packaged pin must name both versions, not prescribe VC++ or OpenSSL.

* fix(lbug): stamp an FTS phase so repair stays usable after an in-place abort

A native CREATE_FTS_INDEX abort leaves no skip reason; the next run infers
it from the dirty flag, and --repair-fts must not treat that phase as a
half-written graph.

* fix(lbug): park an in-place FTS crash WAL without wiping the graph

An FTS abort after a successful checkpoint must reopen the live index on
macOS, Windows, and Linux. Staging never parks the live WAL; readers keep
today's large-WAL refusal.

* fix(lbug): refuse read-only opens of an FTS-poisoned WAL

MCP and serve cannot repair a leftover in-place abort. Fail before the
native open and name --repair-fts, on macOS, Windows, and Linux.

* fix(lbug): name a vendor-neutral Windows OpenSSL prerequisite

OQ1 is unanswered here so GitNexus does not ship OpenSSL DLLs. Windows
FTS now asks for a system OpenSSL 3 runtime instead of Git Bash PATH.

* test(lbug): inject the FTS vendor root and redact it on HTTP and MCP

Path-loaded artifacts no longer vary with HOME. Tests pass an injected
vendor tree and assert search warnings never leak a filesystem path.

* docs(lbug): document load-only as the global FTS install default

Analyze still overrides to auto. Packaged per-platform artifacts load
before any network install on macOS, Windows, and Linux.

* docs(lbug): format the FTS install-policy README table

Prettier does not run on Markdown in pre-commit, so the U10 table wrap
needs its own formatting commit.

* fix(lbug): skip FTS CREATE after a persisted native abort

A recovered analyze run was retrying CREATE_FTS_INDEX from skipReason
alone. Keep that skip until --repair-fts, fail closed on unsupported
tuples, and honor the checkpoint warrant for park/repair.

* fix(lbug): honor checkpoint flushed warrant and align FTS tests with packaged vendor

A no-op CHECKPOINT must not satisfy the FTS park warrant, and CI still asserted HOME-only FTS isolation after analyze started path-LOADing the packaged artifact.

* test(lbug): accept a nonempty incremental write set in the #2790 recovery check

FTS-phase recovery can incremental-add files (changed=0, added=1). That is not the #2790 empty-diff wipe skip.

* fix(lbug): compare FTS home versions to the core pin and tighten the publish filename gate

Ladybug's ~/.lbdb/extension directory is the runtime/core version; treating it as the artifact version false-diagnosed skew. The publish guard now rejects a path-escaping filename the same way the fetch script does.

* test(lbug): seed FTS e2e fixtures from the packaged vendor artifact

A machine with no ~/.lbdb copy should still run the vendor-survivorship cases; the seed no longer depends on HOME or a network install.

* Address PR review feedback (#3274)

Keep in-place FTS abort evidence after persist so a second CREATE abort
cannot fail-open readers, and close the CLI, loader, embed, and e2e gaps
the review called out.

Note: full npm test hit Ladybug worker-pool startup failures under memory
pressure; tsc and 180 targeted unit tests passed.

* Address PR review feedback (#3274)

Run the vendored-path symlink guard on the OS matrix, put e2e HOME
fixtures on Ladybug's real extension layout, pin the embed crash-WAL
gate before the writable open, and let analyze writers park through
missing-shadow recovery.

* fix(lbug): keep --repair-fts CI green after vendored-first FTS

Never-installed warning fixtures must not inspect a packaged vendor binary, and a failed dirty restamp must not abort an otherwise successful --repair-fts run.

* test(cli): give the #1169 analyze e2e the same 90s Windows budget as its sibling

The first #1169 persist-meta case was still on a 60s spawn/it budget and was killed banner-only on windows-latest after the FTS warning fixture no longer failed the shard first.

Co-authored-by: Cursor <cursoragent@cursor.com>

* test(ci): reweight Windows shards after the FTS e2e grew

Vendored-first HOME fixtures pushed fts-extension-e2e to ~6 minutes on windows-latest, so the old 146s weight packed it with skills-e2e and blew the 20-minute watchdog.

fix(analyze): load VECTOR before the incremental writeback touches embedding rows (#2623) (#2624)
* feat(lbug): add ensureEmbeddingRowDmlSafe VECTOR gate for embedding-row DML

LadybugDB refuses every mutation of a table carrying an HNSW index while the
VECTOR extension is not loaded on that connection: DELETE and CREATE raise a
Binder exception, DROP TABLE is refused while the index references it, and SET
segfaults the process. Dropping the index is not an available recovery either —
CALL DROP_VECTOR_INDEX is itself a VECTOR-extension function and is undefined in
exactly that state.

Add a single primitive that loads VECTOR under the analyze install policy and,
only when that fails, reads CALL SHOW_INDEXES (which works without the
extension) to decide whether an index actually exists to trip over. No call
sites yet.

* test(lbug): pin the #2623 VECTOR gate for embedding-row DML

Three cases: no index + VECTOR unavailable stays safe (no needless
escalation); index present + VECTOR unavailable is reported blocked AND the
raw deleteNodesForFiles genuinely throws 'extension is not loaded' (proving the
hazard is real, not theoretical); index present + VECTOR loadable is safe, the
delete works, and the HNSW index survives — the invariant run-analyze relies on
when it keeps the index across a surgical incremental run.

* fix(analyze): load VECTOR before the incremental writeback touches embedding rows

Incremental analyze died on every content change once a repo had built
code_embedding_idx:

  Analysis failed: Binder exception: Trying to delete from an index on table
  CodeEmbedding but its extension is not loaded.

The surgical writeback's first statement is deleteNodesForFiles' CodeEmbedding
join-delete, but nothing on that path loaded VECTOR until Phase 4 — so the
engine refused the delete. This is an ordering defect, not an environment one:
it reproduces on machines where VECTOR loads fine. The dirty-flag recovery then
forced a full rebuild on the next run, which is why it read as 'just slow'.

Call ensureEmbeddingRowDmlSafe() once, before the escalation gate and before any
row is touched — the same 'index lifecycle before row DML' seam dropSearchFTSIndexes
occupies for FTS (#2589). Unconditional, because a DB carrying the index from an
earlier --embeddings run hits the same wall on a plain incremental run. When
VECTOR truly cannot load the table is immutable (the index cannot be dropped
without the extension either), so the run falls through to the existing
wipe-and-COPY escalation with a message naming cause, consequence and remedy.

Fixes #2623

* test(analyze): pin the #2623 VECTOR-before-embedding-DML ordering end-to-end

Sibling of the #2589 FTS drop-before-delete suite, same shape: drive the real
runFullAnalysis incremental path over a real git repo and a real LadybugDB,
seed real embedding rows, build the HNSW index, then assert the index state at
the exact moment deleteNodesForFiles is invoked.

Both cases were confirmed to discriminate — with the run-analyze change
reverted they fail with the reported 'Trying to delete from an index on table
CodeEmbedding but its extension is not loaded', and pass with it:
  - surgical path: the run completes, the index is still present AND
    extension_loaded at delete time, exactly one row per nodeId survives, and
    the untouched file's rows are preserved
  - blocked path: with GITNEXUS_LBUG_EXTENSION_INSTALL=never the run escalates
    to a full DB write and says so, instead of crashing

Also applies prettier's reindent to the run-analyze log ternary.

* docs(lbug): cite the pinned LadybugDB version in the #2623 probe note

The probe matrix behind ensureEmbeddingRowDmlSafe was first recorded on
0.18.0, but gitnexus/package-lock.json pins 0.18.2 (#2587). Re-ran every case
on 0.18.2: refused DELETE, refused CREATE, SIGSEGV on SET, DROP_VECTOR_INDEX
undefined, DROP TABLE refused, SHOW_INDEXES readable with extension_loaded
intact. Identical on both, so the design is unchanged — only the citation was
wrong.

* fix(analyze): preserve embeddings across the VECTOR-blocked rebuild, and check the catalog before loading

Three follow-ups from reviewing the fix itself.

1. Data loss on the blocked path. Escalating wipes the DB files, and Phase 3.5
   restores embedding rows from cachedEmbeddings — which deriveEmbeddingMode
   only populates when meta.stats.embeddings > 0. A DB holding embedding rows
   that its meta does not account for therefore had every vector destroyed
   silently by a rebuild it never asked for. Probe on a 3-file repo: 3 rows
   before, 0 after, no warning. Read the rows before escalating (a plain MATCH,
   no extension needed) so the existing restore has something to restore, and
   say so in the log. The blocked-path test now asserts the seeded rows survive
   exactly once, and that assertion fails without this rescue.

2. Catalog before extension. ensureEmbeddingRowDmlSafe loaded VECTOR first and
   only read SHOW_INDEXES on failure, so every incremental analyze on a machine
   without VECTOR paid a bounded out-of-process INSTALL attempt plus an
   'extension unavailable' warning — including repos that never built an
   embedding index and can never hit this bug. One local catalog read settles
   that case first; the load is attempted only when an index actually gates DML,
   or when the catalog cannot be read.

3. Dead branch. targetConn is always the module singleton there, so the
   isSharedSingletonConn ternary could never take its second arm. Collapsed to
   withConnLock.

* feat(doctor): live-probe the VECTOR extension instead of printing the static platform capability

Review finding on #2624 (MEDIUM), and exactly what #2623's reporter hit:
doctor printed 'VECTOR index: available' — derived from a static platform
check — while every incremental analyze on the same machine was dying on an
unloaded VECTOR extension. The FTS line was switched to a live LOAD probe for
the identical contradiction under #2374; VECTOR now gets the same treatment.

probeVectorExtensionLoad shares the FTS probe's implementation (bounded,
offline-safe, never runs the installer) and doctor's semantic-mode line now
follows the probe, not the platform: without a loadable extension the vector
index can be neither built nor queried, so search really is on exact scan.

The load-error classifier's remedies are label-parameterized so the VECTOR row
stops dispensing FTS-specific advice — 'run analyze --repair-fts' repairs FTS
indexes only and was actively wrong for a missing vector extension. Default
label stays 'FTS'; every existing caller and pinned remedy string is unchanged.

* fix(lbug): remove the stale Windows VECTOR gate — the extension ships for win_amd64

The codebase categorically refused VECTOR on Windows (platform !== 'win32' in
isVectorExtensionSupportedByPlatform, plus a hard early-return in
loadVectorExtension) on the strength of an early-era report that in-process
INSTALL VECTOR could SIGSEGV (#1365). That belief is stale, verified directly:

- the extension server hosts win_amd64 VECTOR artifacts for every 0.18.x
  extension version — v0.18.0 and v0.18.1 both serve a real 14 MB PE32+ DLL
  (curl-probed; 'file' confirms PE32+ x86-64)
- the pinned 0.18.2 core resolves its extension directory to 0.18.1
  (strace-verified LOAD open()), so the pinned version's Windows artifact
  exists too
- INSTALL now runs in a spawned child (installDuckDbExtensionOutOfProcess), so
  even a crashing installer kills only the child and degrades to unavailable —
  the original hazard cannot reach the parent process any more

Windows now takes the same runtime path as every other OS: try LOAD, install
out-of-process when policy allows, degrade to exact scan when it truly fails.
The MCP semantic-search lane loses its static platform gate too — it always
attempts the vector index and falls back to the exact scan on runtime failure,
with a once-per-backend diagnostic naming the real error instead of a
platform-policy message. isVectorExtensionSupportedByPlatform is deleted;
getRuntimeCapabilities reports the platform capability as available everywhere
and defers machine truth to the live probe.

Windows CI is the enforcement: the vector suites skip visibly only when the
extension genuinely cannot load, so green Windows lanes now actually exercise
VECTOR instead of silently skipping by policy.

* test(lbug): pin the catalog-read-failure fallback in ensureEmbeddingRowDmlSafe

Review finding on #2624 (LOW): the one branch where the gate cannot cheaply
prove safety — SHOW_INDEXES itself erroring — was exercised only by inference.
Force it with a Connection.prototype.query spy over the real DB: the catalog
read fails, and the gate must fall through to actually attempting the
extension load (asserted via the recorded statement stream) rather than
guessing, returning true here because the extension is loadable.

* fix(mcp): load VECTOR on the pool's shared Database so the semantic vector lane actually works

Review finding on #2624 (MEDIUM): extension load scope is per-Database
(probe-verified — LOAD on one connection enables QUERY_VECTOR_INDEX on every
connection of the same Database), and the pool pre-warm loaded only FTS. So
LocalBackend's vector lane has ALWAYS raised 'Catalog exception: function
QUERY_VECTOR_INDEX is not defined' through the pool and silently fallen back
to the exact scan — repos above the 10k exact-scan cap got empty semantic
results. The serve path was unaffected (the embedding pipeline loads the
extension itself).

Mirror the FTS line at BOTH load sites — doInitLbug's pre-warm and
initLbugWithDb's external-Database adoption — under the same load-only
contract (the read pool never triggers a network install), tracked by a new
SharedDB.vectorLoaded flag reset where ftsLoaded resets.

The new pool test is discriminating and deliberately closes the writable core
adapter before the pool opens: a shared/injected Database would inherit the
VECTOR load from test seeding and pass either way, so the case forces the pool
onto its OWN fresh read-only Database where only the pre-warm can make the
lane legal. Verified: fails at the pre-fix tree with the exact Catalog
exception, passes with the fix.

* ci: run the #2623 ordering suite on Windows/macOS and pre-install VECTOR alongside FTS

Two review findings on #2624, both landing in existing seams:

- scripts/cross-platform-tests.ts gains incremental-vector-extension-ordering
  .test.ts: the win32 VECTOR gate is gone in this PR, so the #2623
  drop-ordering + blocked-path escalation must be proven on the
  windows-latest native addon, not just Ubuntu. (The review's claim that
  lbug-delete-nodes-for-files.test.ts was also missing was wrong — it has
  been on the roster since #2409.)
- scripts/ensure-fts.ts now pre-installs VECTOR under the same best-effort
  auto-policy contract, so every sharded CI process LOADs from ~/.lbdb
  instead of racing its own bounded out-of-process INSTALL; the workflow's
  extension cache already covers it (path is the whole extension dir — key
  kept for cache continuity). The cross-platform job sets
  GITNEXUS_REQUIRE_VECTOR=1 beside GITNEXUS_REQUIRE_FTS so a genuinely
  unavailable VECTOR is a loud failure, never a silent skip.

Windows/macOS cannot be executed locally; the PR's CI lanes are the proof for
this commit. Linux smoke: ensure-fts.ts reports both extensions ready; all 79
roster entries resolve.

* test(pool): register loadVectorExtension in the pool unit-suite mocks

The pool adapter's new loadVectorExtension import surfaced in four suites that
mock lbug-adapter.js with explicit factories (vitest fails loudly on a missing
mocked export). Register the export in each — resolving false where the
suite's world assumes no vector, true where it mirrors FTS — and extend
lbug-pool-fts-load.test.ts, the suite that owns pre-warm extension loading,
with the vector pair: successful load cached per shared Database, failed load
retried on the next open, both pinned to policy load-only.

* test(analyze): use POSIX literals for graph paths in the #2623 ordering suite

First Windows CI run of this suite (it joined the cross-platform roster this
PR) failed with 'Parser exception: Invalid input <MATCH (n:Function) WHERE
n.filePath = '>' — path.join produces backslashes on Windows, and a backslash
inside the seed helper's single-quoted Cypher literal breaks the parser. The
graph stores repo-relative filePaths with forward slashes on every OS, so
graph-side paths are POSIX literals now (the incremental-orchestration
convention); path.join stays only for real filesystem access.

The same Windows lane also proved the substance this suite exists for:
lbug-vector-extension passed 7/7 on windows-latest — the extension installed,
loaded, and built a real HNSW index there — and the pool vector-lane and DML
gate suites passed too. This commit fixes the harness, not the fix.
