fix: web citation/code panel bugs and serve analyze/route hardening (#3348)
* chore: ignore local Vercel link artifacts

Keep .vercel and env files out of the repo after a local preview link.

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

* fix(web): repair citation chips, code panel line math, stale agent state

Audit findings in the web client, each verified against the source:

- RightPanel: citation chips ([[path:10-20]], [[Class:Foo]]) were wired to a
  stub resolver that always returned null, so clicking any citation did
  nothing. Expose resolveFilePath from useAppState and use it.
- CodeReferencesPanel: graph startLine/endLine are 1-based but were treated
  as 0-based, so the highlighted range and scroll target were off by one
  line; AI citation cards always rendered "code not available" because the
  snippet loader was a stub. Fetch per-citation snippets via /api/file.
- useAppState: sendChatMessage read llmSettings.activeProvider outside its
  deps (stale provider capabilities after switching provider);
  initializeAgent trapped projectName at '' for callers without an override
  (system prompt labelled the codebase "project"); the embeddings 409 dedup
  matched a message the server never sends for same-repo jobs.
- tools.ts impact: for path targets every symbol defined in the file shares
  the filePath, so the disambiguation always picked the first row and could
  analyze an arbitrary symbol while reporting a file impact. Prefer the File
  node.
- useSigma: the layout timeout called stop() but never kill(), leaking one
  ForceAtlas2 Web Worker plus four graph listeners per completed layout.

* fix(server): release repo lock on cancel, IPC-first worker cancel, route hardening

Audit findings in gitnexus/src, each verified against the source:

- analyze-launch: cancelJob marks the job failed before the worker exits,
  so the exit handler's terminal early-return skipped releaseLockOnce and
  the repo stayed locked ("Another job is already active") until restart.
  Release on terminal exit and when forkWorker bails on a terminal job.
- analyze-job: cancellation now sends { type: 'cancel' } over IPC first and
  signals only after a 15s grace. On Windows child.kill('SIGTERM') is a
  forceful termination, so leading with it could kill the worker inside a
  LadybugDB write. Mirrors core/auto-sync/analysis-worker-launch.
- api resolveRepo: a job that FAILED during the hold-queue wait fell through
  to the { __timedOut } sentinel ("taking longer than expected") instead of
  404; only /api/repo checked the sentinel, so graph/query/search/file/grep/
  embed/delete crashed on entry.storagePath with a 500 after a 5 minute hang.
  Return null on failed jobs and check the sentinel in every consumer.
- api processes/process/clusters/cluster: resolve ?repo= through the HTTP
  resolver (documented policy on resolveRegisteredRepoEntry) and pass the
  registered absolute path to the backend; add the standard rate limiter.
  The raw param previously reached the MCP resolver, which runs a
  cwd-relative realpathSync probe + registry refresh on a bare-name miss
  and accepts unambiguous partial names.
- api body handling: Express 5 leaves req.body undefined without a JSON
  content type, turning "Missing X" 400s into TypeError 500s; body-parser
  4xx errors (malformed JSON, over-limit) were also reported as 500.
- /api/file: the lexical path.relative check cannot see symlinks; re-check
  containment on realpath so a cloned repo containing evil -> /etc/passwd
  cannot read outside the root.
- repo-manager unregisterRepo: used the lenient reader, so a transient read
  error (EBUSY/EPERM racing another process's atomic rename) turned into
  writing [] and deregistering every repo. Use the strict-if-present reader.
- clean --branch: compared registry paths with raw path.resolve instead of
  the canonical registryPathEquals used everywhere else (macOS /private/var,
  Windows short names / drive-letter case) and reported indexed branches as
  not indexed.

Tests: cancelJob IPC-before-signal contract; /api/file symlink escape (403)
and in-repo symlink (200), skipped where the host cannot create symlinks.

* chore: keep example env files visible and ignore local Cursor config

.env* also hid gitnexus/.env.example and eval/.env.example. .vercel was already ignored. The web app's .cursor/ stays local, including its MCP file.

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

* Add realtime execution ops dashboard for Vercel monitoring.

Expose /api/ops snapshots over the local serve process and a ?view=ops SPA panel so analyze/embed jobs can be watched live from the hosted web UI.

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

* fix: address gitnexus-check review on cite/embed/resolve paths

Pass req into resolveRepo for process/cluster routes, tighten same-repo embed 409 handling, guard empty citation paths, fix snippet retry races, and drop the lone-File ambiguity fallback.

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

* fix(ops): harden CORS, redact paths, and bound ops streams

Restrict Vercel CORS to exact production hosts, omit raw repo paths/URLs from the unauthenticated ops feed, rate-limit and cap SSE connections, and fix dashboard SSE/poll edge cases.

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

* fix(web): stabilize citation fetches and file impact matching

Retry cancelled snippet loads without duplicate in-flight reads, cap range-less citation downloads, and make impact file matching unique-suffix-aware with a synthetic File target when LIMIT drops the File node.

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

* fix(web/ops): close gitnexus-check review threads on SSE and redaction

Cap citation reads, reconnect ops on applied server URL, skip SSE onError after abort, and strip URL query/fragment from public repoName.

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

* fix(ops): abort SSE on poll fallback and harden repoName parsing

Prevent dual SSE+poll after a failed safety snapshot, skip overlapping poll ticks, ignore aborted streamSSE onError, and basename Windows drive-letter URLs so ops never leaks path segments.

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

* fix(ops/web): close gitnexus-check threads on SSE budget and credential leak

Keep finite SSE retries across short 200s, strip backend URL userinfo before ?server=, and redact progress messages on the public ops feed.

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

* Address PR review feedback (#3348)

Restore 0-based GraphNode line math, redact public job poll/error fields, fix omit-?repo= 400, hold the analyze lock across cancel-during-settle, and restore the Vercel shared compile.

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

* fix(cli): contain leftover-slot reclaim to the slot and keep --stale status honest

Preview and force now share one branches/ containment rule, nested junctions cannot walk a sibling index, and a mid-loop git failure no longer claims leftovers were not deleted after a successful rm.

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

* refactor(cli): share leftover-slot helpers without changing reclaim behavior

Pull the rolling I/O pool and owned-cwd storage lookup into one place so clean --stale/--branch and leftover listing stop restating the same ownership and concurrency paths.

* chore(autofix): apply prettier + eslint fixes via /autofix command

* Address PR review feedback (#3348)

Keep the omitted-repo snapshot instead of re-listing, stop citation and ops races, redact full public repo URLs, and restore fake timers in teardown.

* Address remaining PR review feedback (#3348)

Store graph node citation lines as 0-based offsets and correct the default-port origin comment.

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

* Address remaining PR review feedback (#3348)

Redact public SSE progress text, stop citation append retries from
cancelling in-flight reads, and keep the ops dashboard from showing a
stale snapshot or clearing a failed Connect.

Note: pre-existing failure in incremental-index-extension-dml-gate and other lbug/env unit tests not addressed by this PR.
Co-authored-by: Cursor <cursoragent@cursor.com>

* Address remaining PR review feedback (#3348)

Prune citation snippets when AI refs are cleared, and poll /api/ops at 2s so the fallback stays under the 60/min limit.

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

* fix(ci): apply prettier class order for format check (#3348)

CI quality/format runs root-only npm ci, so prettier-plugin-tailwindcss
sorts scrollbar-thin without the web Tailwind catalog.

* Address PR review feedback (#3348)

- Require a unique suffix match for graph-backed citation paths so
  ambiguous names like index.ts no longer open the first graph file.

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

* Address PR review feedback (#3348)

- Require a path-component boundary so unique citation suffixes cannot match filename substrings like myindex.ts

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

* fix(server): redact filesystem paths in ops text

Unauthenticated /api/ops and poll replay worker errors. URLs were
scrubbed but home-directory and Windows paths still leaked.

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

* fix(server): omit repoPath from public SSE frames

/api/ops lists job ids, so the unauthenticated progress stream
must not replay the analyzed filesystem path.

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

* fix(web): treat embed lock 409 as a busy error

Analyze and embed share the same lock string. Mapping that 409 to
embedding hid an in-flight analyze as a successful embed start.

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

* fix(web): bound impact File path suffix matches

Unbounded endsWith let lib/foo.ts select src/mylib/foo.ts. Require
an exact path or a unique /suffix, matching resolveUniqueIndexedPath.

* fix(server): keep canceled analyze slot until exit

Marking failed before the worker exited let a second POST start
cloneOrPull against a LadybugDB file still being written.

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

* fix(server): skip Windows SIGTERM on job dispose

child.kill('SIGTERM') is TerminateProcess there. Ask over IPC first
and leave the 15s grace timer to SIGKILL.

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

* fix(server): let process routes skip the analyze hold

GET /api/processes and /api/clusters always waited up to 300s.
?awaitAnalysis=false fails fast; default still waits like /api/repo.

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

* test(web): cover public ops and analyze SSE user flows

Lock the unauthenticated dashboard and analyze complete/fail/cancel paths so a leaked repoPath, token, or home path cannot ship unnoticed.

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

* Address PR review feedback (#3348)

Keep caller cancel reasons over the worker's generic IPC, skip publish while cancel is pending, and redact scp-style remotes on the public ops feed.

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

* Address remaining PR review feedback (#3348)

Release the analyze slot when a worker fails to spawn, and omit branch refs from the unauthenticated ops feed.

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

* fix(server): do not reuse an analyze job that is pending cancel

A dying same-repo job still occupies the single slot; 202-reuse would
attach a new client to a cancel in flight.

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

* fix(server): hold the analyze lock until the worker exits after cancel

Cancel error IPC used to drop the repo lock while the child was still
checkpointing. Abort settle immediately on pending cancel so the slot
is not held for a 60s disk poll.

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

* fix(server): redact known repo paths with spaces in public ops text

Known repoPath/repoUrl literals are replaced first so a clone dir with
spaces cannot leak past the whitespace-bounded path regex.

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

* fix(server): return the live job on analyze and embed DELETE

Hard-coding failed made clients retry immediately and 409 while the
child still occupied the slot. resolveRepo now returns not-found as
soon as that job fails instead of waiting out the hold timeout.

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

* test(web): drive public analyze and ops through a live gitnexus serve

Spawn the real backend and observe requests instead of intercepting
them, so slot occupancy, redaction, and reconnect stay honest.

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

* refactor(web): reuse code-panel helpers and drop dead UI aliases

Citation fetches already had selectedNodeFileRange and snippetRepoKey;
the impact File suffix filter already handled exact paths.

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

* chore(autofix): apply prettier + eslint fixes via /autofix command

* Address PR review feedback (#3348)

- Skip createJob reuse after cancel IPC is consumed while the child remains
- Hold the repo lock until exit when complete IPC races a pending cancel
- Scrub full remote URLs before known repoUrl prefixes in public ops text
- Reject unique impact File suffix matches from a truncated LIMIT 10 page
- Make live e2e helpers bound probes, clean up failed startups, and wait out the cancel slot

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

* fix(web): open live e2e pages on the Vite host CI actually bound

Absolute 127.0.0.1:5173 navigation refused on Actions because wait-on
and Vite use localhost (often ::1). Honor FRONTEND_URL when set, else
pick the first of localhost / 127.0.0.1 that answers.

* Address PR review feedback (#3348)

Hold the analyze lock until worker exit when cancel aborts settle, and assert GitLab failure chrome does not leak host or path.

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

* fix(web): keep live analyze e2e under the analyze rate limit

POST /api/analyze allows 10 requests per minute per IP. The slot-free
helper re-POSTed every 400ms while a cancelled worker was exiting, spent
that budget, and the lock test's hold request got 429 instead of 202.

- postAnalyze waits out a 429 using the RateLimit reset and retries
- slot polling backs off to 2s and leaves a small POST budget for callers
- the slot probe is a clone that fails before any worker fork, so the
  probe itself no longer holds the slot after reporting failed
- the lock test holds the slot with a real local analyze
- token and GitLab tests wait for a free slot before posting from the UI
- request fetches carry a timeout; teardown signals the serve process group
- an empty FRONTEND_URL falls back to the default base URL

* Address PR review feedback (#3348)

- ops view: a `?server=` link no longer auto-connects to another origin
  while a deploy token is held; it prefills and waits for Connect
- analyze completion: a local-path run reconnects by the path this client
  submitted, so duplicate basenames stay collision-safe without repoPath
  on the public SSE frame
- stale slot cleanup: revalidate each nested directory (lstat + realpath)
  right before readdir, so a mid-cleanup junction swap aborts instead of
  walking an outside tree; list phases run sequentially so the slot-I/O
  cap is global
- e2e: 429 backoff honours the caller deadline; the unreachable-backend
  ops test navigates through the resolved frontend URL
- drop the unused `repo` member from the clean integration helper

* feat(server): reconnect after analyze by an opaque repo id

Public job views and the SSE terminal frame no longer carry repoPath, and
repoName is not unique, so a post-analyze reconnect by name could load a
same-named sibling. The server now issues `repoId`: an HMAC of the
canonical registry path under a per-process random key. It is set on
complete jobs (ops view, analyze poll, SSE terminal frame) and matches
the new `id` on `GET /api/repos` entries. The web client resolves it to
the exact entry path on completion; unknown ids fall back to the name.
This covers URL clones and folder uploads, and replaces the local-path
only fallback.

With reconnect off the label, public `repoName` for a branch-pinned URL
clone is the repository name, not the `<repo>__<branch slug>` registry
name, so the requested branch stays off the unauthenticated feed.

* Address PR review feedback (#3348)

- stale slot cleanup: a descendant that vanishes before its unlink is
  treated as removed instead of aborting the reclaim
- e2e teardown: escalate to SIGKILL on the process group when the live
  backend ignores SIGTERM for 5s
- ops view: drop the dead initial value CodeQL flagged

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* Address PR review feedback (#3348)

- public redaction: a known repoPath now also consumes its descendant
  tail, so `<repoPath>/src/secret.ts` becomes `[path]` instead of
  `[path]/src/secret.ts`; a same-prefix sibling is left to the path scrub
- e2e: the cancel test waits for the analyze slot the previous failed
  local-path job still holds; `fetchOps` carries the request timeout
- docs: SSE terminal payload and RepoAnalyzer `onComplete` describe
  `repoId` resolution

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* Address PR review feedback (#3348)

- RepoAnalyzer: drop a completion that resolves after unmount, so a slow
  /api/repos lookup cannot switch repos after the sheet was dismissed
- e2e: select the local-path input by test id (the placeholder differs on
  Windows); the slot probe's job wait honours the caller's deadline

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* test(server): assert the public SSE terminal frame in analyze-api

The #2790 terminality tests still expected `repoPath` on the terminal
frame. This PR replaced it with the opaque `repoId`, so assert that shape
and that the analyzed path never appears in the stream.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* test(web): wait for the analyze slot between duplicate-repo setup runs

The server now keeps the single analyze slot until the worker exits, even
after its job reports complete. repo-path-identity posted the second
duplicate's analyze immediately and got 409 in CI. Use the shared
slot-aware POST, which also waits out a 429.

* fix(storage): close review findings for external indexes and retention

Re-inspect ownership under the analyze lock, fail-closed when the

unless contentRetention is full.

Keep hook fallbacks inside the current worktree, compare foreign-local slots canonically, and make storage fixtures survive ownership validation.

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

* Fix macOS hook test expecting realpath'd registry paths.

resolveHookRepo returns the written registry path, not a filesystem realpath, so the assertion must match that.

* Address gitnexus-check warnings on hook install docs and slot tests.

The Cursor troubleshooting list omitted registry-query.cjs, and the writable-slot test only checked that isDirectory exists instead of that the path is a directory.

* Align the HTTP catalog source-scan with skippable resolveRepo validation.

resolveRepo lists fresh repos with validate: options.validateStorage !== false so DELETE can skip prune; the test still required a literal validate: true.

* Harden storage path sinks so CodeQL path-injection and ReDoS alerts clear.

Contain every filesystem probe inside the resolved storage slot with the inline path.relative idiom, reject filesystem-root slots, and trim slot basenames in linear time.

* Settle bridge stamps before writing so CI size/mtime matches stay stable.

LadybugDB can still flush into bridge.lbug after close+rename; persist whole-millisecond mtimes and wait for consecutive stats to agree so a freshly written pair matches.

* Type the settled bridge stat as fs.Stats so tsc does not see bigint.

Awaited<ReturnType<typeof fsp.stat>> collapsed the bigint overload and broke prepare/typecheck on CI.

* Keep the bridge mtime stamp exact so same-size swaps still fail the pair check.

* fix(embeddings): retry unparseable 200 responses and survive partial embedding failures (#2790)

A long-running embedding job against an OpenAI-compatible endpoint could lose
hours of work to a single transient glitch, then refuse to recover on the next
run. Four defects compounded:

1. An HTTP 200 carrying a truncated or non-JSON body was never retried.
   `classifyOutcome` treats any 2xx as success, and the `resp.json()` parse ran
   after `resilientFetch` had already returned, so the parse failure surfaced as
   a terminal error. Measured: a 503 got 3 attempts, a garbage 200 got 1.

   The parse and the response-shape check now run inside the `fetchImpl`
   callback, so a bad body is classified as a retryable failure and gets the
   same backoff as a 5xx. This also stops a garbage 200 from calling the circuit
   breaker's `recordSuccess()`, which previously erased accumulated failures and
   meant an endpoint alternating 5xx and garbage-200 could never trip it.

2. One failed `embedBatch` sub-batch aborted the entire pipeline. Failures are
   now tolerated: the sub-batch's node ids are collected and all of their
   embedding rows are deleted, so those nodes hold zero rows and are re-embedded
   later. Deleting rather than keeping partial rows is deliberate — chunk arrays
   are flat over a 16-node batch and sliced by 8, so a node's chunks can straddle
   a sub-batch boundary, and surviving rows carry the current content hash. The
   hash maps collapse per-chunk rows last-row-wins, so a partially embedded node
   would read as fresh forever and never regenerate its missing chunks.

   A run that fails 5 sub-batches in a row still aborts, and rethrows the first
   error of the streak rather than the last: after 3 failures the circuit breaker
   opens, so later errors degrade into "circuit open, retry in 30s" while the
   first still names the real defect.

3. The Phase 5 `embeddingCount === 0` fail-fast could not tell "wrote nothing"
   from "could not ask" — the count query's catch was silent. The count is now
   tri-state and only a known zero after real work is fatal. A non-numeric count
   previously bypassed the gate entirely, because `Number()` returns NaN and
   `NaN === 0` is false, and then serialized as `embeddings: null`. An unverified
   count no longer certifies `capabilities.vectorSearch.status`.

4. `saveEmbeddingCheckpoint` wrote a completion-shaped meta: it advanced
   `lastCommit`, wrote the new `fileHashes` and cleared `incrementalInProgress`.
   The first checkpoint window fires before a single embedding exists, and on a
   full rebuild the graph is still in a staging database that a crash discards.
   The next run then diffed against the advanced hashes, saw no changes and
   preserved the old graph — the "skipping wipe" symptom in the report. It now
   re-reads meta and replaces only the checkpoint, matching what the server
   endpoint already did.

A partially failed run keeps its checkpoint with the failed ids in
`pendingNodeIds`, so the next plain `analyze` regenerates them through the
existing resume path. Clearing it would have been silent data loss: a plain run
derives `shouldGenerateEmbeddings: false` once embeddings exist, so the pipeline
would never have run again. The old crash-and-abort self-healed only by accident,
via the checkpoint its crash left behind. `gitnexus status` reports the index
incomplete until the nodes recover, and `--drop-embeddings` still abandons them.

`POST /api/embed` is the pipeline's other caller and was discarding the result,
reporting "Embeddings complete" for a partial run. It now persists the pending
ids and reports the run as failed with the underlying endpoint error.

* fix(embeddings): abort a run whose sub-batch failure ratio is too high (#2790)

The consecutive-failure ceiling only catches a total outage, because any
successful sub-batch resets it. An endpoint under load shedding that alternates
success and failure never trips it, so the run walks the whole corpus, deletes
every failed node's rows and exits 0 having dropped a large fraction of the
index. The retained checkpoint made that visible in `gitnexus status`, but a run
that drops a quarter of the corpus should tell the operator to fix their
endpoint, not leave them to notice a status flag.

Adds a cumulative guard: abort once more than 25% of attempted sub-batches have
failed, evaluated as the run progresses and gated behind a floor of 20 attempted
sub-batches. The shape follows Resilience4j's circuit breaker (failure rate plus
a minimum-sample floor) because it is the only one of the surveyed designs that
answers the small-repo case — a three node repo can fail one sub-batch and never
accumulate enough sample for a ratio to mean anything. The rate sits below a live
traffic breaker's 50% because a batch indexer's job is to index the whole corpus
rather than serve degraded traffic, and above Hadoop's single-digit
`failures.maxpercent` because tolerating transient hiccups is the point of the
change this follows.

The guard reuses the existing break-then-cleanup path, so the failed batch's
DELETE still runs before the rethrow, and it wraps the retained first-error-of-
streak rather than inventing a new one, so the message names both the ratio and
the underlying endpoint failure.

* fix(server): record the embedding count after /api/embed so the next analyze cannot wipe it

`POST /api/embed` generated embeddings and wrote them to the database but never
wrote `stats.embeddings` into meta.json. Its checkpoint writer replaced only
`embeddingCheckpoint`, and the finalize write folded in nothing else.

So a repo embedded purely through the server kept whatever count the last CLI
`analyze` stamped, which is 0 for a repo analyzed without embeddings. The next
CLI run read `existingEmbeddingCount = 0`, `deriveEmbeddingMode` returned
`shouldLoadCache: false`, and `gitnexus analyze --force` wiped the database with
no cache load. Every server generated embedding was silently destroyed, with no
warning — the user just lost semantic search.

The route now measures the live count with the same query the CLI uses and folds
it into both meta writes. The measurement is tri-state and deliberately never
falls back to 0: an unverified count is written as absent rather than as zero,
because a wrong-low value is exactly what arms the wipe. It is taken after
`flushWAL()` and inside `withLbugDb`, so it describes durable rows and the
connection is still open. A partial run records its honest count too, alongside
the retained checkpoint, so the next CLI run preserves the partial index instead
of discarding it.

Found while working #2790; not part of that issue.

* fix(embeddings): retry short 200 bodies and stop laundering body-phase timeouts

Two gaps in the #2790 retry fix, both found by review.

A 200 carrying `{"data": []}` or fewer vectors than inputs passed the
in-`fetchImpl` shape check, because `every(isEmbeddingItem)` is vacuously true
for an empty array. `resilientFetch` then classified it `success` and called
`recordSuccess()`, erasing the outage signal, and the cardinality check in
`httpEmbed` threw terminally one attempt later. That is exactly the pair of
properties #2790 was filed about, still broken for this body shape — and worse
than before the fix, since the pipeline now tolerates the error by deleting
those nodes' rows instead of aborting loudly. The count check moves inside the
retried callback; the outer one stays as a backstop.

The `.json()` catch also swallowed every rejection, not just parse errors.
`AbortSignal.any([caller, timeout])` is wired to the body stream, so a stalled
body rejects with a DOMException — which, wrapped in a plain Error, defeated
`classifyOutcome`'s terminal-network test. Measured: the same TimeoutError got
3 attempts and "unparseable response" when raised during the body read, but 1
attempt and "timed out after 180000ms" when raised by fetch itself, and three
such sub-batches opened the process-global breaker that `recordNeutral()`
exists to protect. Abort-like DOMExceptions are now re-raised unchanged.

The dimension check stays outside the loop deliberately: it validates against
`config.dimensions ?? DEFAULT_DIMS`, not the request-dimensions argument, and a
width mismatch is a configuration error where retrying only triples latency and
books failures against a healthy endpoint.

Adds the negative assertion the review found missing: response body text must
never reach the user-facing error string.

* fix(embeddings): scale the sub-batch failure-ratio floor to the run

The cumulative guard needed 20 attempted sub-batches before a failure rate could
abort anything — roughly 160 chunks, or ~80 embeddable nodes at the default
subBatchSize of 8. A 50-node repo whose endpoint sheds every other sub-batch
fails half of them and still exits 0: the ratio guard is below its floor, and
every intervening success resets the consecutive ceiling.

The floor was a good choice for a first run over a small repo, where one failure
out of one sub-batch is 100% and means nothing. The defect is that every resume
run has that shape by construction — its node set is only the pending ids — so
the guard was structurally off in the one run whose entire purpose is retrying
against the endpoint that already failed.

The floor is now sized to the run: clamp(ceil(totalNodes / 16), 5, 20). The
lower bound keeps the case the flat floor protected; the upper bound preserves
today's behavior above 320 nodes and avoids a proportional-only floor perversely
weakening the guard at scale, where a sixteenth of a 20k-node repo would be 1250
sub-batches of damage before a rate could fire. Resilience4j can use a constant
minimumNumberOfCalls because a breaker sits on an unbounded call stream; a batch
indexer has a finite budget, so a constant can exceed the whole run.

The ratio is still evaluated only inside the catch. That is already its local
maximum — both counters have just incremented — so sampling more often would
only ever observe lower ratios.

Also: a failing cleanup DELETE no longer swallows the abort, which was
discarding the retained first-error-of-the-streak that names the real endpoint
fault; `ceilingError` is renamed `abortError` since it carries the ratio abort
too; and three `{ error }` log keys become `{ err }` (#2114 — an arbitrary key
serializes to `{}`, losing message and stack).

* fix(analyze): one tri-state embedding counter, and stop partial runs wedging later runs

The tri-state count doctrine this branch introduced was applied at two of its
three CLI sites, and the two implementations that were meant to mirror each
other had already drifted.

`measurePersistedEmbeddingCount` moves to `core/embedding-count.ts` — beside
`embedding-mode.ts`, with the same no-native-imports property, and outside
`core/embeddings/` so the lazy-embeddings convention (#2370) still holds. All
three call sites now share it.

  - The mid-run `onCheckpoint` counter ran the query bare. A throw there — DB
    busy, connection closed, read-only, the VECTOR DML lock (#2623) — rejected
    the callback out of `runEmbeddingPipeline` and killed the analyze before
    Phase 5 could apply the tri-state that exists for exactly this case. A
    non-numeric cell wrote `stats.embeddings: null` to disk mid-run.
  - Phase 5 used `?? 0` while the server used `?? Number.NaN`, under a comment
    asserting both measured the field the same way. `Number.isFinite(0)` is
    true, so a no-row answer became a *measured* zero and hard-failed a run
    whose embeddings had all persisted.
  - The unknown-count fallback read `existingMeta`, assigned once at run start,
    so it republished the pre-run figure over the fresher count the terminal
    checkpoint had already written. With a prior count of 0 that armed the wipe
    chain: hasExisting false, shouldLoadCache false, and the next --force
    discards live embeddings. It now re-reads the latest on-disk meta, and an
    unverifiable count retains a recovery marker instead of clearing it.

A completed-but-partial run also planted a landmine. Its checkpoint is stamped
with the run's embedding identity, so a later plain `gitnexus analyze` from a
hook, a CI job, or a shell without GITNEXUS_EMBEDDING_URL resolved provider
'local' and threw before any phase ran — after an exit-0 run, where previously
only a visible crash left that state. `--force` did not help: the resume gate
inspected only `--drop-embeddings`.

`RepoMeta.embeddingCheckpoint` gains `kind` to tell the two situations apart.
An 'interrupted' marker (or one with no kind, so markers already on disk keep
the stricter path) still fails closed — its nodes may be half-written, and
resuming under a foreign model would mix vector spaces. A 'partial' marker
names nodes the pipeline already deleted to zero rows, so nothing is at risk: an
identity mismatch drops the pending set with a warning and continues. `--force`
now discards a checkpoint, and `attempts` bounds the retry at
EMBEDDING_RESUME_MAX_ATTEMPTS (3, matching the HTTP embedder's and the WAL
driver's existing per-operation budgets) so a node the endpoint deterministically
rejects converges instead of keeping the repo incomplete forever.

* fix(server): close the SSE stream on terminal job status, not a progress phase

A tolerated partial run reached SSE clients as a clean success — a regression in
this branch's own claim that /api/embed reports a partial run as failed.

The pipeline emits `phase:'ready'` unconditionally before returning, including
when it dropped nodes. The route mapped that to `'complete'`, and
`mountSSEProgress` treated a terminal-looking *progress phase* as terminal:
write the event, `res.end()`, `unsubscribe()`. The route's own
`updateJob({status:'failed'})` then fired into a stream with no listener, and
the web app had already shown "ready". Before this branch the pipeline threw,
which produced `phase:'error'` and did reach the client. Pollers on
GET /api/embed/:jobId were unaffected, so the two consumers disagreed.

Terminality is a property of the job, so the relay now asks the job. Remapping
`ready` alone would have left the trap armed: the `error -> 'failed'` mapping
has the identical shape and would emit `event: failed` with `error: undefined`
before the catch block fills the message in. `ready` is additionally remapped to
`finalizing` so a poller no longer sees `status:'analyzing'` next to
`progress.phase:'complete'`. The single-terminal-event property (#2264) is
preserved on both the clean and partial paths, and /api/analyze is unaffected —
its terminal progress phase is 'done', never 'complete'.

`AnalyzeJob` gains an optional `partial` payload so a client can tell a partial
run from a total failure without a new status member; it is absent on every
other job, so existing payloads stay byte-identical. Consuming it in
gitnexus-web is left to that app's owner — today it renders both as the same
red retry chip.

`resolveEmbedRunOutcome` moves to `embed-run-outcome.ts` and `mountSSEProgress`
to `sse-progress.ts`, both free of Express/LadybugDB/MCP imports, and the local
count copy is replaced by the shared `core/embedding-count.ts`. Reaching three
pure functions previously meant importing the whole server: measured at ~20s
against a 30s test timeout, with one observed timeout failure. That file is now
1.6s.

* docs: document the partial embedding index and its recovery

A run can now finish exit 0 with a partial embedding index, which neither
operator doc described.

GUARDRAILS' "Embeddings vanished after analyze" Sign keys its trigger on
`stats.embeddings` being 0 and lists "the only ways to end up at zero". A
partial run stamps an honest non-zero count and sets `embeddingCheckpoint`, so
the operator's actual symptom is `incompleteReasons:
["embedding-checkpoint-pending"]` — a state that Sign cannot match. Adds a Sign
for it and drops the exhaustive framing from the existing one.

RUNBOOK gains the recovery path: a plain `gitnexus analyze` is correct and needs
no flag, because a retained checkpoint forces generation for the pending nodes
regardless of flags. Also corrects two stale claims — that `stats.embeddings` is
always freshly measured (it can carry forward when the count query cannot
answer, which is why `capabilities.vectorSearch.status` is the certified read),
and that later analyzes must always pass `--embeddings` or lose their vectors,
which contradicts Non-negotiable 5.

* refactor(embeddings): one owner for the checkpoint record and the abort predicate

Cleanup pass over the #2790 review fixes. No behavior change except where
noted; the two exceptions are both cases where the code was lying to the
operator or to the other half of itself.

The previous pass extracted `core/embedding-count.ts` because two hand-copied
bodies of "measure the embedding count" had drifted inside a single change. It
then created a second pair of hand-copied publishers — of
`RepoMeta.embeddingCheckpoint` — and those had drifted too: the CLI armed the
attempt counter only after clearing its identity gate, the server derived it
from the resumed marker alone. Only one of the two READERS implemented `kind`
at all, so a 'partial' marker written by `gitnexus analyze` and resumed through
POST /api/embed still hit the permanent wedge `kind` exists to remove.

`core/embedding-checkpoint.ts` now owns the record: `checkpointKind` (the one
home for absent-means-interrupted), the three minters, `nextAttemptCount`, and
`decideEmbeddingResume`, which both gates route through. Five mint sites and
two resume gates become one implementation each.

`resilient-fetch.ts` exports `isTerminalNetworkError` and `classifyOutcome`
calls it, replacing a caller-side copy of the same DOMException test whose
docstring promised it "mirrors classifyOutcome exactly" — an invariant enforced
by prose, where a divergence silently reverts body-phase timeouts to being
retried three times and charged to the shared breaker.

The ratio-guard floor now divides by the run's actual `subBatchSize` instead of
a constant 16 that assumed the default of 8. At `subBatchSize: 32` the old
formula demanded more sub-batches than the run contains, leaving the guard
structurally off — the exact failure the scaled floor was introduced to fix,
and sub-batch size is tuned mainly for the flaky endpoints it protects.

Two operator-facing corrections:

  - The count-recovery marker was stamped `kind: 'partial'` with an empty
    pending set, so `gitnexus status` reported "N node(s) lost their embeddings"
    where N is zero. It gets its own kind and its own incomplete reason.
  - `decideEmbeddingResume` initially keyed its skip-the-identity-gate branch on
    an empty pending set, assuming that meant the count-recovery marker. It does
    not: `onCheckpoint` mints an 'interrupted' marker with no pending nodes
    after every post-window save. That silently cleared an interrupted marker
    under a foreign provider instead of failing closed. Keyed on `kind` now,
    with a regression test.

Also: `isTerminalJobStatus` adopted at the seven sites that still hand-copied
it, including the one gating the single-terminal-event emit; `mountSSEProgress`
re-export dropped and `server-sse-payload.test.ts` repointed at the extracted
module, which takes it from 24.60s to 0.408s — the test that motivated the
extraction was still paying the cost it was meant to remove; the count-mismatch
message and the SSE test harness deduplicated; per-batch error strings made
lazy (~75k needless `new URL()` per large run); `retryable: true` dropped as a
field that can never be false; ~110 lines of restated rationale reduced to
pointers at their canonical home.

feat: configure prettier with pre-commit hook (#563)
* feat: configure prettier with pre-commit hook integration

Add prettier, lint-staged, and prettier-plugin-tailwindcss at the repo
root with husky pre-commit hook integration. Moves husky from
gitnexus/ to root package.json for reliable hook installation.

- Root package.json with prepare/format/format:check scripts
- .prettierrc with endOfLine:lf and tailwindStylesheet for TW v4
- .prettierignore excluding fixtures, vendor, generated, *.d.ts, *.md
- .gitattributes enforcing LF line endings for Windows consistency
- Pre-commit hook uses direct node_modules/.bin/ paths (no npx)

* style: apply prettier formatting to entire codebase

One-time bulk format. No logic changes.
Use .git-blame-ignore-revs to skip this commit in git blame.

* chore: add .git-blame-ignore-revs for prettier format commit

* perf: pre-commit hook runs only tests related to staged files

Use vitest --related to scope test execution to tests that import
the changed files, instead of running the full suite on every commit.

* perf: remove vitest from pre-commit hook, keep in CI only

Pre-commit now runs lint-staged + tsc only. Tests run in CI
(ci-tests.yml) where they belong — keeps commits fast.

* ci: add prettier format check to quality workflow

PRs will now fail if code isn't formatted with prettier.

feat: unify web and cli ingestion pipeline (#536)
* feat: add server-side ingestion API (POST /api/analyze, SSE progress)

Extract core analysis orchestration from CLI into shared run-analyze.ts
module. Add server-side analyze endpoints so the web app can trigger
ingestion via HTTP instead of running the full pipeline in-browser.

New files:
- src/core/run-analyze.ts — shared runFullAnalysis() orchestrator
- src/server/analyze-job.ts — job manager (single-slot, dedup, SSE events)
- src/server/analyze-worker.ts — forked child process (8GB heap, IPC)
- src/server/git-clone.ts — shallow clone/pull with SSRF protection

API endpoints:
- POST /api/analyze — start analysis (returns 202 + jobId)
- GET /api/analyze/:jobId — poll job status
- GET /api/analyze/:jobId/progress — SSE progress stream

Security: URL validation blocks private IPs and non-HTTP schemes.
Path validation requires absolute paths. Git stderr not leaked to API.

* feat(web): add server-side analyze UI (Phase 2)

Add "Analyze on Server" flow to the web app's Server tab so users
can trigger server-side ingestion from the browser. On completion,
the graph is automatically loaded via the existing connectToServer flow.

New files:
- AnalyzeProgress.tsx — progress bar with phase label, elapsed time, cancel

Modified files:
- backend.ts — startAnalyze(), streamAnalyzeProgress() SSE client
- DropZone.tsx — analyze URL input + button below Connect section
- App.tsx — onServerAnalyze handler wires analyze -> connect flow

* feat: add job cancellation, timeout, and child process tracking (Phase 3)

- DELETE /api/analyze/:jobId — cancel running analysis (SIGTERM to worker)
- 30-minute timeout kills long-running workers automatically
- Child process refs tracked in JobManager for cleanup on shutdown
- dispose() kills all active children on SIGINT/SIGTERM
- Web cancel button now calls server DELETE endpoint
- cancelAnalyze() added to web backend client

* refactor(web): remove browser ingestion pipeline (Phase 4)

Delete 16 duplicated ingestion files, 2 unused service files
(git-clone, zip), and tree-sitter parser-loader from gitnexus-web.
All ingestion now runs server-side via POST /api/analyze.

Deleted (18 files, ~5,000 lines):
- core/ingestion/*.ts (16 pipeline processors)
- core/tree-sitter/parser-loader.ts (WASM tree-sitter loader)
- services/git-clone.ts (isomorphic-git client-side clone)
- services/zip.ts (JSZip extraction)

Simplified:
- DropZone.tsx — server-only (removed ZIP/GitHub tabs)
- ingestion.worker.ts — removed runPipeline/runPipelineFromFiles
- useAppState.tsx — removed pipeline callbacks
- App.tsx — removed handleFileSelect/handleGitClone
- main.tsx — removed Buffer polyfill for isomorphic-git
- types/pipeline.ts — removed PipelineResult/serialize helpers

Kept: cluster-enricher.ts (LLM enrichment, still used by worker)

Dependencies now removable: web-tree-sitter, isomorphic-git,
@isomorphic-git/lightning-fs, jszip (estimated 3-4MB bundle savings)

* refactor(web): sync graph schema from CLI + delete WASM grammars

Sync graph/types.ts and lbug/schema.ts from the CLI (source of truth)
to the web module so the browser LadybugDB can handle all node and
relationship types the server pipeline produces.

Synced types: Route, Tool, Section node labels; HANDLES_ROUTE, FETCHES,
HANDLES_TOOL, ENTRY_POINT_OF, WRAPS, QUERIES relationship types;
description fields on Function/Class/Interface/Method/CodeElement.

Deleted: public/wasm/ directory (14 tree-sitter WASM grammars + core).
Removed deps: web-tree-sitter, isomorphic-git, @isomorphic-git/lightning-fs,
jszip, buffer, @types/jszip (~3-4MB bundle savings).

* feat: create gitnexus-shared package for unified type definitions

Create a new gitnexus-shared package that is the single source of truth
for types shared between the CLI and web modules:

- SupportedLanguages enum (15 languages)
- Graph types: NodeLabel, NodeProperties, RelationshipType, GraphNode, GraphRelationship
- Schema constants: NODE_TABLES, REL_TYPES, REL_TABLE_NAME, EMBEDDING_TABLE_NAME
- Pipeline types: PipelinePhase, PipelineProgress

Both gitnexus (CLI) and gitnexus-web import from gitnexus-shared via
file: dependency. Each package re-exports and extends with platform-specific
additions (CLI: KnowledgeGraph with mutation methods; Web: simpler KnowledgeGraph).

This ensures types can never drift between packages — adding a new
language, node type, or relationship type in gitnexus-shared automatically
propagates to both consumers.

* refactor: import shared types directly from gitnexus-shared at call sites

Replace all re-export patterns with direct imports from gitnexus-shared.
72 files updated across CLI and web:

- SupportedLanguages: 49 CLI files now import from 'gitnexus-shared'
  instead of '../config/supported-languages.js'
- GraphNode, GraphRelationship, NodeLabel: 22 CLI + 10 web files now
  import from 'gitnexus-shared' instead of local re-export wrappers
- NODE_TABLES: api.ts imports from 'gitnexus-shared'
- PipelineProgress: useAppState.tsx imports from 'gitnexus-shared'

Local types.ts files now only define platform-specific KnowledgeGraph
(CLI has mutation methods, web has add-only). No more re-exports.

* fix: update lock files for gitnexus-shared, remove stale vite polyfills

Add gitnexus-shared@1.0.0 to lock files so npm ci succeeds in CI.
Remove buffer polyfill and global define from vite.config.ts (isomorphic-git was removed).

* fix(security): add write guard to HTTP /api/query, fix CORS proxy bypass

- Add isWriteQuery() check to POST /api/query handler — blocks CREATE,
  DELETE, SET, MERGE, DROP, etc. via HTTP API (guard was only in MCP
  pool adapter and browser-side, not the HTTP server path)
- Extend CYPHER_WRITE_RE with CALL, INSTALL, LOAD keywords
- Fix CORS proxy subdomain bypass: endsWith('github.com') allowed
  'evil-github.com'. Now requires exact match or '.github.com' suffix

* feat(server): enhance /api/search with enrichment, add /api/grep, strip graph content

- POST /api/search: add mode param (hybrid|semantic|bm25), server-side
  enrichment returns connections/cluster/processes per result in one call
  (collapses 31 sequential HTTP calls to 1 for the agent search tool)
- GET /api/grep: regex search across indexed file contents, eliminates
  need to transfer all file contents to browser
- GET /api/graph: strip content field by default (80-95% payload
  reduction). Use ?includeContent=true for backward compat
- Add LRU cache invalidation hook point for future caching

* feat(server): add /api/embed endpoint for server-side embedding generation

- POST /api/embed: triggers embedding pipeline via onnxruntime-node
  with JobManager for single-slot concurrency, timeout, and dedup
- GET /api/embed/:jobId: poll job status
- GET /api/embed/:jobId/progress: SSE stream with heartbeat, event IDs,
  and X-Accel-Buffering:no header for proxy compatibility
- DELETE /api/embed/:jobId: cancel running embedding job
- Maps embedding pipeline phases (ready→complete, error→failed) to
  JobManager status conventions

* feat(web): create consolidated BackendClient module

Single HTTP client replacing backend.ts, server-connection.ts, and
worker HTTP helpers. Includes:
- Typed methods: runQuery, search (enriched), grep, readFile, connect
- Generic streamSSE<T> utility extracted from analyze progress pattern
- BackendError with discriminated code field (network/server/client/timeout)
- Embed API: startEmbeddings, streamEmbeddingProgress, cancelEmbeddings
- Search with mode param (hybrid|semantic|bm25) and enrichment

* refactor(web): rewrite Graph RAG tools for backend-only HTTP queries

- Search tool: uses enriched /api/search (1 call replaces 31 sequential queries)
- Cypher tool: removes browser-side embedding; {{QUERY_VECTOR}} routes to
  /api/search with mode:'semantic' instead of local transformers.js
- Grep tool: uses /api/grep instead of in-memory fileContents map
- Read tool: uses /api/file instead of fileContents map lookup
- Impact tool: getCallSiteSnippet now async via /api/file
- createGraphRAGTools now accepts GraphRAGBackend interface instead of
  7 separate function params + fileContents map
- createGraphRAGAgent simplified to (config, backend, context?)
- Removed imports: embedder, lbug/schema (replaced with gitnexus-shared)
- Net: -205 lines

* refactor(web): delete WASM infrastructure, remove 7 packages (-5242 lines)

Delete browser-side LadybugDB, embeddings, search, and worker:
- gitnexus-web/src/core/lbug/ (adapter, csv-generator, schema, query-result)
- gitnexus-web/src/core/embeddings/ (embedder, pipeline, text-gen, types)
- gitnexus-web/src/core/search/ (bm25-index, hybrid-search)
- gitnexus-web/src/workers/ingestion.worker.ts (828 lines)
- gitnexus-web/src/services/server-connection.ts (merged into backend-client)
- gitnexus-web/src/types/lbug-wasm.d.ts

Remove packages: @ladybugdb/wasm-core, @huggingface/transformers,
comlink, minisearch, vite-plugin-wasm, vite-plugin-top-level-await,
vite-plugin-static-copy

Update vite.config.ts: remove WASM plugins, COOP/COEP headers,
worker config, optimizeDeps exclude

Update imports: App.tsx, DropZone, Header, AnalyzeProgress,
BackendRepoSelector, useBackend → backend-client

* refactor(web): replace Worker/Comlink with direct BackendClient calls

- useAppState: remove Worker instantiation, Comlink.wrap, apiRef.
  All queries now go through BackendClient HTTP functions directly.
- Agent runs on main thread (I/O-bound LLM streaming, not CPU-bound)
- initializeAgent: creates GraphRAGAgent with GraphRAGBackend interface
  bound to BackendClient methods (runQuery, search, grep, readFile)
- startEmbeddings: calls POST /api/embed + SSE progress instead of
  running browser-side transformers.js pipeline
- switchRepo: no longer loads graph into WASM DB or extracts fileContents
- App.tsx: handleServerConnect simplified (no fileContents, no loadServerGraph)
- Delete old backend.ts (replaced by backend-client.ts)
- Net: -396 lines

* fix(web): fix await-in-map build error in agent streaming

Move dynamic import of AIMessage outside .map() callback to avoid
"await can only be used inside an async function" build error.

* fix(web): remove stale apiRef references that broke chat functionality

sendChatMessage referenced apiRef.current (deleted Worker ref) which
would throw TypeError. Replaced with agentRef.current guard since agent
now runs on main thread.

* fix(server): dispose embedJobManager on shutdown, fix job mutation

- Add embedJobManager.dispose() to shutdown handler (was missing,
  causing cleanup timer to keep Node process alive)
- Replace direct job.repoName/status mutation with updateJob() to
  ensure SSE event emission for initial status change

* fix(server): parameterize Cypher, harden grep, unify SSE endpoints

- Search enrichment: replace string interpolation with executePrepared()
  using $nid parameter binding to prevent Cypher injection
- Add executePrepared() to core lbug-adapter (prepare/execute pattern)
- /api/grep: add 200-char pattern length limit (ReDoS protection),
  search files on disk instead of loading entire corpus into memory
  (constant memory usage regardless of repo size)
- Extract mountSSEProgress() shared helper for SSE streaming — both
  analyze and embed endpoints now have consistent heartbeat (30s),
  event IDs (reconnection support), and X-Accel-Buffering header

* refactor(web): remove dead code from Worker-era architecture

- Remove loadServerGraph no-op function, interface member, and all consumers
- Remove testArrayParams stub and interface member
- Remove fileContents state from GraphStateProvider (never populated in
  server-side architecture)
- Remove forceDevice parameter from startEmbeddings (server-side, no device choice)
- Replace phantom EmbeddingProgress type with inline { phase, percent }
- Replace resolvePathFromContents (needed fileContents Map) with graph-based
  file path resolution using filePathIndex built from graph nodes
- Fix: AI citation grounding ([[file.ts:10]]) now works via graph node lookup
  instead of broken fileContents-based resolution

* fix(web): use streamAgentResponse for full tool_call/reasoning streaming

Replace naive agent.stream() loop that only handled content chunks with
streamAgentResponse() generator from agent.ts. This properly routes:
- reasoning tokens (before/between tool calls)
- tool_call events (name, args, status)
- tool_result events (completed tool output)
- content tokens (final answer after all tools done)

Previously the onChunk handler for tool_call/tool_result/reasoning was
dead code since the streaming loop only emitted content events.

* fix(web): resolve CI type errors from dead code removal

- Import GraphNode/GraphRelationship from gitnexus-shared in graph.ts
  (not re-exported from local types.ts)
- Add Route, Tool entries to NODE_COLORS and NODE_SIZES constants
- Add PipelineResult type to web types/pipeline.ts
- Remove fileContents from CodeReferencesPanel and RightPanel
- Remove testArrayParams and forceDevice from EmbeddingStatus
- Remove forceDevice args from startEmbeddings() calls in App.tsx
- Fix embeddingProgress property accesses for simplified type

* fix(ci): add setup-gitnexus-web action, build shared once per job

- Remove prepare script from gitnexus-shared (tsc not available during
  npm ci of consuming packages)
- Create .github/actions/setup-gitnexus-web composite action: builds
  gitnexus-shared then runs npm ci for gitnexus-web
- setup-gitnexus action: already builds gitnexus-shared for CLI jobs
- ci-quality typecheck-web: uses setup-gitnexus-web (DRY)
- ci-e2e: uses setup-gitnexus-web (DRY)
- ci-tests: gitnexus-shared already built by setup-gitnexus, just
  install web deps without rebuilding

* fix(ci): use prepare script so gitnexus-shared builds during npm ci

Move typescript from devDependencies to dependencies in gitnexus-shared
so the prepare script (tsc) works when npm resolves file: deps during
npm ci. No GHA modifications needed — npm handles the build lifecycle
automatically.

Remove manual gitnexus-shared build steps from setup-gitnexus and
setup-gitnexus-web actions.

* fix(ci): build gitnexus-shared explicitly in setup actions

The file: dependency protocol doesn't reliably run prepare scripts
because devDependencies aren't installed first. Instead of fragile
lifecycle hacks, build gitnexus-shared explicitly in both setup actions:
- setup-gitnexus: npm install && npm run build in gitnexus-shared/
- setup-gitnexus-web: same, before npm ci in gitnexus-web/
- ci-tests: shared already built by setup-gitnexus, web just npm ci

No prepare script, no dist in git, no typescript as a prod dependency.

* fix: remove CALL from CYPHER_WRITE_RE — breaks FTS and vector search

CALL is used by read-only procedures: CALL QUERY_FTS_INDEX(...) and
CALL QUERY_VECTOR_INDEX(...). Adding it to the write guard blocked all
FTS search, causing 3 test failures. The database is opened in read-only
mode as defense-in-depth against write procedures via CALL.

Keep INSTALL and LOAD in the blocklist (genuinely dangerous).

* fix(web): update vercel.json for gitnexus-shared, remove COOP/COEP

- Add installCommand that builds gitnexus-shared before installing
  web deps (Vercel doesn't know about the monorepo file: dependency)
- Remove Cross-Origin-Opener-Policy and Cross-Origin-Embedder-Policy
  headers (no longer needed — WASM LadybugDB removed)

* fix(web): update tests for deleted modules

- Delete csv-generator.test.ts (tests deleted WASM-only csv-generator)
- Update security-guards.test.ts: import NODE_TABLES/REL_TYPES from
  gitnexus-shared instead of deleted src/core/lbug/schema
- Update server-connection.test.ts: import normalizeServerUrl from
  backend-client, remove extractFileContents tests (function deleted)

* fix(e2e): remove Server tab click — UI is now server-only

The DropZone no longer has ZIP/GitHub/Server tabs (browser ingestion
was removed). The server URL input is directly visible on the landing
page. Update e2e test to skip the tab click and go straight to input.

All 5 e2e tests pass locally.

* refactor: use gitnexus-shared for PipelinePhase/PipelineProgress types

CLI was duplicating PipelinePhase and PipelineProgress locally instead
of importing from gitnexus-shared. Updated all consumers to import
directly. Also removed dead code: SerializablePipelineResult,
serializePipelineResult(), deserializePipelineResult().

* fix(server): address PR #536 review — security, race conditions, dead code

- Fix path traversal in POST /api/analyze: split into isAbsolute + normalize check
- Add shared repo lock (activeRepoPaths) preventing concurrent analyze+embed on same repo
- Fix 202 response returning actual job.status instead of hardcoded 'queued'
- Add 30-minute timeout for embedding jobs (was missing unlike analyze jobs)
- Fix DropZone calling startAnalyze without setting backend URL first
- Add SSE reconnect with exponential backoff (3 retries) and Last-Event-ID
- Fix normalizeServerUrl to return base URL (no /api suffix) — clear contract
- Delete dead code: proxy.ts, server-graph-hydration.ts, pipeline.ts re-export barrel
- Update LoadingOverlay to import PipelineProgress directly from gitnexus-shared

* fix(server): fix repo lock key mismatch and embed cancel race

- Use getStoragePath(targetPath) as lock key in analyze handler to match
  embed handler's entry.storagePath — keys now always align
- Guard embed completion: don't overwrite 'failed' with 'complete' when
  job was cancelled while pipeline was still running
- Remove unused jobType parameter from acquireRepoLock
- Log backend.init() errors instead of silently swallowing

* fix: add gitnexus-shared as a local dependency in package-lock.json

* refactor: move language detection to gitnexus-shared, add syntax highlighting for all 15 languages

Move getLanguageFromFilename() from CLI to gitnexus-shared with COBOL
support added. Add getSyntaxLanguageFromFilename() for Prism-compatible
syntax highlighting covering all 15 code languages plus auxiliary
formats (json, yaml, markdown, html, css, bash, sql, xml).

Refactor CodeReferencesPanel to use shared function instead of a local
30-line switch. Delete dead gitnexus-web/src/config/supported-languages.ts
(web already imports SupportedLanguages from gitnexus-shared).

* feat(web): add first-time user onboarding with auto server detection

Replace the manual "Connect to Server" panel with an automatic onboarding
flow that guides first-time users through starting the GitNexus server.

Server detection:
- useBackend hook polls via setTimeout chain (3s, no overlap)
- Page Visibility API pauses polling when tab is hidden
- SSE heartbeat (/api/heartbeat) for instant disconnect detection

Onboarding UI (OnboardingGuide.tsx):
- Step-by-step flow: copy command → run → auto-connect
- Smart command: shows `gitnexus serve` in dev, `npx gitnexus@latest serve` in prod
- Node.js version auto-detected from package.json via Vite define
- Faux terminal windows with copy-to-clipboard, platform tabs, polling indicator

Transitions (DropZone.tsx):
- Crossfade wrapper with snapshot pattern for smooth phase transitions
- Three phases: onboarding → success (1.2s hold) → loading → graph
- Auto-recovery: falls back to onboarding if server dies or connect fails

Server changes:
- GET /api/heartbeat: SSE endpoint for liveness detection
- GET /api/info: version, launch context, Node.js version
- npm run serve script for local development
- app.disable('x-powered-by') hardening

* feat(web): add repo analysis UI, SSE heartbeat, and review fixes

Repo analysis:
- AnalyzeOnboarding: empty-state card when server has zero repos
- RepoAnalyzer: GitHub URL + Local Folder tabs with browse button
- Header repo dropdown: click project badge to switch repos or analyze new
- DropZone 'analyze' phase integrated into Crossfade transitions

Reliability fixes from 5-agent review:
- Polling: stop scheduling timers when tab hidden, restart on visibility return
- Heartbeat: exponential backoff (1s/2s/4s, 3 retries) prevents graph loss on blip
- RepoAnalyzer: completion timer tracked in ref, cleaned up on unmount
- DropZone: standardized card padding (p-7), heading sizes (text-lg)

Accessibility:
- prefers-reduced-motion global CSS rule (WCAG 2.3.3)
- focus-visible rings on CopyButton
- cursor-pointer on all Header buttons
- Consistent rounded-xl on all dropdowns

Cleanup:
- Deleted dead AnalyzeSheet.tsx (219 LOC) and BackendRepoSelector.tsx (89 LOC)
- Fixed AnalyzeProgress lucide import (lucide-react → @/lib/lucide-icons)

* fix(server): resolve analyze worker fork crash in dev mode

The forked analyze worker was crashing immediately with exit code 1
when running via `npm run serve` (tsx). Two issues:

1. Worker path resolved to `analyze-worker.js` but only `.ts` exists
   in the source directory — the `.js` file is only in `dist/`.

2. On Windows, bare `--import tsx` in execArgv fails because Node's
   ESM resolver for --import uses the child's CWD, not the parent's
   node_modules. Windows also rejects raw paths as `d:` is not a
   valid URL scheme.

Fix: detect dev vs prod via `import.meta.url` extension. In dev mode,
resolve `tsx/esm` to an absolute `file://` URL via `pathToFileURL()`
anchored to the parent's `createRequire` context. This works on all
platforms and doesn't depend on the child's CWD or PATH.

Also captures child stderr for better crash diagnostics.

Verified: `POST /api/analyze` with GitHub URL completes successfully
in dev mode (tsx) — status goes from cloning → analyzing → complete.

* fix(server): add worker auto-retry, error handling, and crash diagnostics

Worker resilience:
- Auto-retry up to 2 times with exponential backoff (1s, 2s) on crash
- SSE progress shows "Retrying after crash (1/2)..." during retry
- Captures child stderr for crash diagnostics in failure message
- AnalyzeJob tracks retryCount per job

Server error handling:
- app.listen wrapped in Promise so EADDRINUSE/EACCES propagate cleanly
- serve.ts catches startup errors with friendly messages and exit code 1
- EADDRINUSE gets actionable guidance (stop other process or --port flag)
- Global uncaughtException/unhandledRejection handlers prevent silent exits
- DEBUG=1 env var shows full stack traces

* feat: add e2e tests for onboarding flows, worker retry, and error handling

E2E tests (onboarding.spec.ts — 11 tests):
- Flow 1: OnboardingGuide shown when server unreachable (6 tests)
- Flow 2: Auto-connect with success card, analyze phase for zero repos
- Flow 3: Analyze form — GitHub URL validation, Local Folder tab, tab switching
- Flow 4: Repo dropdown in exploring view (skipped without live server)

Updated server-connect.spec.ts:
- Replaced manual Connect button flow with auto-connect waitForGraphLoaded

Server resilience:
- Worker auto-retry (2 attempts with exponential backoff) on crash
- Friendly error messages for serve startup failures (EADDRINUSE etc.)
- Global uncaughtException/unhandledRejection handlers prevent silent exits
- app.listen wrapped in Promise for proper error propagation

* refactor(shared): enforce exhaustive language coverage via Record types

Replace the if/else chain in getLanguageFromFilename with two exhaustive
Record<SupportedLanguages, ...> maps:

- EXTENSION_MAP: every language → its file extensions
- SYNTAX_MAP: every language → its Prism syntax identifier

Adding a new member to the SupportedLanguages enum without adding it to
both maps now produces a TypeScript compile error:

  Property '[SupportedLanguages.NewLang]' is missing in type...

This matches the existing pattern in languages/index.ts (providers table)
which already uses `satisfies Record<SupportedLanguages, LanguageProvider>`.

Three compile-time enforcement points now exist:
1. EXTENSION_MAP in language-detection.ts (file extensions)
2. SYNTAX_MAP in language-detection.ts (Prism syntax identifiers)
3. providers in languages/index.ts (LanguageProvider instances)

* feat(web): load source code from server and scroll to selected line

CodeReferencesPanel now fetches file content via GET /api/file when a
node is selected, instead of showing "Code not available in memory".

- Fetches via readFile() from backend-client when selectedFilePath changes
- Shows loading spinner while fetching
- After content loads, auto-scrolls to the selected node's startLine
- Highlights the selected line range with a cyan left border
- Cancels in-flight fetch if selection changes before it completes

Also: refactored language-detection.ts to use exhaustive Record types
(EXTENSION_MAP and SYNTAX_MAP) so adding a new SupportedLanguages enum
member without implementing extensions/syntax is a compile error.

* feat: buffered file reading for Code Inspector

Server: GET /api/file now supports ?startLine=N&endLine=M for reading
a line range instead of the entire file. Returns { content, startLine,
endLine, totalLines }.

Client: readFile() returns ReadFileResult with metadata. When selecting
a symbol (function, class, method), fetches only ±50 lines around the
symbol's startLine/endLine instead of the full file. File nodes still
fetch the entire file.

SyntaxHighlighter startingLineNumber set from the buffer offset so line
numbers are correct even for partial reads.

* fix: adapt readFile callers to new ReadFileResult return type

tools.ts: readFile comes from GraphRAGBackend interface which returns
Promise<string> (the adapter in useAppState extracts .content), so
revert the { content } destructuring back to plain string assignment.

useAppState.tsx: wrap backendReadFile with { repo } options object
and extract .content to satisfy the GraphRAGBackend interface.

* fix(web): ensure new repos appear in list immediately after analysis

Two fixes:

1. DropZone: handleAnalyzeComplete now passes the repoName through to
   connectToServer so the specific newly-analyzed repo loads — not the
   server's default first repo.

2. App.tsx: fetchRepos() is now awaited BEFORE handleServerConnect in
   both the DropZone and Header flows. This ensures the repo list is
   populated before the exploring view renders, so the new repo appears
   in the header dropdown immediately without a page reload.

* feat: delete repos, re-analyze with force, select after analysis

Server — DELETE /api/repo:
- Acquires repo lock first (409 if analyze/embed in flight)
- Closes LadybugDB, deletes index + clone dir, unregisters, re-inits
- Lock released in finally block

Server — analyze complete:
- backend.init() must succeed before SSE complete fires
- If backend.init() fails, job is marked failed (not complete)

Web — Header repo dropdown:
- Re-analyze: calls POST /api/analyze with force=true, shows spinning
  icon + inline progress bar via SSE
- Delete: acquires lock, aborts any running re-analysis SSE for same
  repo, refreshes list, switches to next repo
- After analysis completes: refreshes repo list, connects to the
  specific repo by name, loads graph, shows in explorer
- Retry with 1.5s backoff on 404 (server may still be reinitializing)

Type safety:
- err: any → err: unknown + instanceof BackendError in retry loop
- Added missing BackendRepo + BackendError imports in App.tsx
