feat: ktx batch — scan resilience, analytics SQL craft, connector hardening (#312)
* docs: add spider2-specs handoff directory for benchmark-driven feature specs

* feat(cli): connection-scoped wiki pages

Add an optional `connections` frontmatter field so database-specific wiki
knowledge can be scoped to a connection without polluting searches about other
databases, while page keys stay a flat, globally-unique namespace.

- connections: single string or list; absent/empty ⇒ unscoped (applies to all)
- wiki_search (MCP) and `ktx wiki --connection` return unscoped ∪ matching
  pages, filtered at the disk-load seam so all three search lanes draw their
  candidate pool from the already-scoped set (not a post-filter)
- wiki_write accepts connections with REPLACE semantics and rejects a
  connection-scoped write whose key collides with a disjoint-connection page
  (data-loss guard; hard error, no silent clobber)
- explicit connection-id args (wiki_search, memory_ingest, ktx wiki) are
  validated against ktx.yaml via a shared assertConfiguredConnectionId, which
  also closes the prior gap where memory_ingest's connectionId was unvalidated;
  persisted ids absent from config warn (not fail) in `ktx status`
- prompt guidance in the wiki_capture skill and external-ingest prompt; the
  session connectionId is surfaced to the memory agent and ingest work units

Implements spider2-specs/specs/01-connection-scoped-wiki.md; intake draft moved
to spider2-specs/done/.

* docs(spider2-specs): add specs/ refinement stage and composite-key join spec

Describe the todo/ → specs/ → done/ pipeline in the README (refined specs are
the durable artifact; intake drafts move to done/ on ship) and add a
MEDIUM-priority spec for multi-column composite-key join detection found during
the first sqlite smoke test.

* feat(cli): add --verbatim ingest mode for authoritative documents

Store each --text/--file document body unchanged as a GLOBAL wiki page
instead of routing it through the memory agent, which may rewrite,
condense, or re-title it. The LLM derives only metadata (summary, tags,
sl_refs) and only for frontmatter fields the document does not already
set; the stored body is written by code and never edited.

- Deterministic page key: files derive it from the filename, inline
  text from its leading Markdown heading (headless inline text is
  rejected — pass it as --file instead).
- Idempotent: re-running the same body is a no-op; a different body at
  the same key fails loudly rather than overwriting.
- Works with llm.provider.backend: none, deriving a degraded summary
  from the heading or first sentence.
- Existing frontmatter (including unmodeled fields like effective_date)
  passes through untouched; --connection-id scopes the page.

* feat(cli): SQL-authoring craft and per-dialect notes tool for the analytics skill

Spec 07: add a dialect-agnostic <sql_craft> block to the ktx-analytics skill (schema discovery, composition, window-function correctness, numeric precision, answer completeness) with one worked window-then-filter example. Workflow steps gain pointers into it; existing guidance is unchanged.

Spec 08: add a read-only sql_dialect_notes MCP tool returning a connection's engine SQL conventions (FQTN form, identifier quoting/case, date/time, top-N idiom, JSON access), resolved through the existing sqlAnalysisDialectForDriver path. Notes are per-dialect markdown files under context/sql-analysis/dialects, served by the tool and copied to dist (package-internal, never installed). Non-SQL connections return a clear KtxExpectedError. The flat skill gains a one-line pointer to the tool.

Both spider2-specs intake drafts move to done/ with implementation notes.

* feat(cli): tolerate objects that fail introspection during scan

Isolate per-object introspection failures so one broken or inaccessible object no longer zeroes out a connection's whole semantic layer: the sqlite and bigquery connectors introspect each object defensively (tryIntrospectObject), the live-database adapter records a scan outcome and fetch report, and enabled_tables accepts catalog.db.name, db.name, or bare names with a clear no-match error. Includes matching ktx-daemon introspection changes, docs, and tests.

* docs(spider2-specs): add 06-scan-tolerate-broken-objects spec

* feat(cli): generalize analytics fan-out rule to multi-hop join chains

The ktx-analytics skill's fan-out rule only reliably caught single-hop
inflation; agents still silently fanned out on multi-hop chains where the
offending one-to-many join sits several hops below the SUM/COUNT and is easy
to miss.

Rewrite the Composition rule so the danger reads as cumulative across the whole
chain (pre-aggregate per measure-owning table), add an affirmative
grain-verification habit (default: pre-aggregate to grain; escape hatch:
COUNT(DISTINCT key) for pure counts only; SUM/AVG of a fanned-out measure must
pre-aggregate), and add one generic wrong-vs-right worked example. Content-only
and dialect-agnostic; no new tool, flag, or config.

Implements spider2-specs/specs/09 and annotates spec 07's one-example
constraint as superseded.

* feat(cli): add panel-completeness, time-series window, and text-encoded numeric SQL craft

Extend the analytics skill's <sql_craft> with three correctness habits and
route the dialect-specific halves through sql_dialect_notes:

- Panel completeness (spec 10): full-domain spine -> LEFT JOIN -> COALESCE for
  "each/every/all/per" questions, defaulted by measure additivity.
- Time-series windows (spec 11): explicit cumulative frames, calendar-range
  rolling windows with minimum-periods guards, and period-over-period via LAG.
- Text-encoded numerics (spec 12): sample distinct values, strip/scale/cast in
  one early CTE, and confirm coverage with a failure-detecting cast.

Add per-dialect Series, Rolling window, and Safe cast notes to all seven
dialect files so the skill stays dialect-agnostic while the engine-specific
syntax lives in sql_dialect_notes. Tests updated and passing (19).

* docs(spider2-specs): add specs 10-12 for analytics SQL-craft additions

Refined specs and completion records for the panel-completeness spine (10),
time-series window recipes (11), and text-encoded numeric parsing (12)
implemented in the preceding commit.

* docs(spider2-specs): add backlog intake drafts 13-14

- 13: canonical authoritative-source measures
- 14: output-completeness final check

* skill(analytics): spec 14 output-completeness + iter1 (active column planning)

Bundles two changes (entangled in SKILL.md; future spider2 iterations land as
separate commits):

- spec 14 (output-completeness): multi-part "answer every requested output" rule
  + a "Final completeness check" in workflow Step 6 and <sql_craft>; analytics
  skill-content test updated; intake draft -> done/, refined spec added.
- iter1 experiment: spec 14's passive end-check did not change behavior on the
  benchmark's output-completeness failures, so (a) the Plan step now writes the
  exact output-column list UP FRONT as a contract the final SELECT must match,
  and (b) "expose identity" -> "project BOTH the entity id and its name" (covers
  both omission directions). All generic craft.

Driven by the Spider 2.0-Lite failure analysis (incomplete output was the
largest failure bucket); benchmark only as motivation.

* skill(analytics): iter2 — deterministic order in string/array aggregation

GROUP_CONCAT/string_agg/array_agg element order is undefined without an explicit
ORDER BY; also note SQLite's default text sort is binary/case-sensitive (uppercase
before lowercase) vs case-insensitive (COLLATE NOCASE). Generic SQLite craft.

Spider 2.0-Lite motivation: an ordered-ingredient-list question failed only on the
within-string element order (right elements, wrong order); benchmark as motivation only.

* feat(mcp): structured, leveled logging for the MCP server

Add one synchronous pino logger per MCP server process, written through the
io.stderr sink: plain JSON when stderr is not a TTY, colorized pino-pretty
(sync, in-process) when it is. Every tool call logs tool.start with its raw
params BEFORE the handler runs and tool.end after (info / warn past
KTX_MCP_SLOW_TOOL_MS / error), correlated by callId plus sessionId, so a
runaway sql_execution leaves a recoverable start line with its exact SQL and
no matching end. HTTP logs session.open/close and wires the previously-dead
transport.onerror to transport.error; stdio routes its transport error
through the logger. Level via KTX_MCP_LOG_LEVEL (default info). Existing
mcp_request_completed telemetry and registerParsedTool are unchanged; no
worker/async transport and no redaction in v1 (logs are local-only).

Implements spider2-specs/specs/15-mcp-server-structured-logging.md and moves
the intake draft to done/.

* feat(mcp): report uptimeMs in MCP server /health

The /health endpoint now includes uptimeMs (monotonic elapsed time since
the server started), mirroring the Python daemon's uptime_ms telemetry
field.

* feat(cli): bound read-query execution with a per-connection deadline

Enforce one shared query deadline (default 30s, overridable per connection via
query_timeout_ms) on every executeReadOnly path, so an accidentally-expensive
LLM-authored query returns a fast "query exceeded Ns" KtxQueryError instead of
hanging the MCP server.

- New shared contract context/connections/query-deadline.ts
  (resolveQueryDeadlineMs, queryDeadlineExceededError); query_timeout_ms added to
  the shared warehouse schema; BigQuery's job_timeout_ms removed.
- SQLite runs the read query in a short-lived forked child process and enforces
  the deadline with SIGKILL. worker_threads + terminate() was tried first but
  cannot interrupt a synchronous better-sqlite3 scan (the native loop never
  yields); SIGKILL reclaims the process in ~2ms and keeps the event loop free.
- Remote connectors apply a real server-side statement timeout and re-wrap their
  own timeout signal as KtxQueryError: Postgres statement_timeout/57014, MySQL
  max_execution_time/3024, Snowflake STATEMENT_TIMEOUT_IN_SECONDS/604, ClickHouse
  max_execution_time + aligned request_timeout/159, SQL Server requestTimeout/
  ETIMEOUT, BigQuery jobTimeoutMs.
- Relationship validation skips a candidate to review on a deadline timeout
  instead of aborting the pass; the deadline surfaces through the existing MCP
  pino logger as a matched tool.start/tool.end(error) pair (no new logging code).

Also fixes a pre-existing, unrelated invalid cast in mcp-server-factory.test.ts
that was breaking tsc -p tsconfig.test.json.

* docs(spider2-specs): mark spec 16 (bounded query execution) done

Append Implementation notes to the refined spec (what shipped, where, and the
worker-thread -> child-process+SIGKILL deviation with its evidence) and move the
intake draft from todo/ to done/.

* skill(analytics): iter3 — measure-as-amount, inter-event gap, top-per-metric career

Three generic interpretation rules: a named business measure (sales/revenue/spend)
means its amount not a row count; "inter-event duration/gap" is LAG/LEAD time-between
events not a magnitude column; "highest across several achievements" aggregates per
metric over the whole history. All three demonstrably FIRE (verified on local008/003/152
SQL). local008 flips to correct (mechanism-aligned). 003/152 still fail on a different
axis (source-column / grouping). Generic craft; benchmark only as motivation.

* skill(analytics): spine-for-extreme-selection + aggregate-over-selected-set

Two generic answer-completeness refinements:
- Selecting the extreme group (lowest/highest count over a period/category
  domain) must rank over the COMPLETE spine, not only groups with fact rows —
  an empty period is a genuine 0 and often the true minimum.
- An aggregate scoped to a per-entity selected set ('avg revenue per actor in
  those top-3 films') is computed ACROSS that set, distinct from the per-item
  value; project both.

* skill(analytics): iter2 — sharpen extreme-selection spine + top-N ranking-measure

- spine-for-extreme: concrete cue that a zero-row period never appears in a
  GROUP BY of the facts; generate the full calendar, LEFT JOIN, COALESCE, then rank.
- aggregate-over-selected-set: top-N selection ranks by the named ranking measure
  (the item's own revenue), independent of the per-item share that feeds the aggregate.

* skill(analytics): iter3 — comparison-between-two-extremes is one wide row

Distinguishes a cross-item comparison ('the difference between the highest and
lowest month' -> single wide row, both extremes side by side + the comparison
column) from 'report a metric for each group' (-> stays long). Generic, question-
derived; targets the wide-vs-long shape gap without affecting per-group long output.

* skill(analytics): iter4 — anchor a period bucket to the named lifecycle event

When a record carries multiple lifecycle timestamps (created/placed, approved,
shipped, delivered, completed, settled) and the question counts/measures records
in a named *completed state* by period ("delivered orders by month", "shipped
items per week"), bucket the period by that named event's own timestamp, not the
record-creation timestamp; the state value is the qualifying filter, the matching
timestamp is the time anchor. Wording priority is explicit — purchased/placed/
created/submitted/ordered keep the start-event timestamp — and a non-temporal
state filter (counts by customer/city/seller with no period) introduces no anchor.

Generic analytics craft: counting completed-state records by their creation date
silently answers "records that later reached that state, grouped by when they
started" instead of the question asked. Surfaced via the spider2-autofix loop;
FAIR_PRODUCT (adversary-screened, restatable from question wording + schema/
semantic-layer lifecycle descriptions, no gold dependency).

* skill(analytics): iter5 — canonicalize observed URL-path variants before page-level analysis

When a question groups/filters/sequences web pages by a path/url column, sample
its distinct values; if the data itself shows /route and /route/ variants for the
same page context, canonicalize in an early CTE (preserve / as root, strip trailing
slashes from non-root paths, map an observed empty path to / only when the column is
a URL path with blank root-page events) and use the canonical path everywhere above.
Explicitly forbids inventing aliases the data doesn't show: no merging different
route names, no stripping query/fragment/host/scheme, no lowercasing, and no
canonicalization when the question asks for raw URL/path or slash-vs-no-slash diffs.

Generic web-analytics craft: raw request logs routinely store the same user-visible
page with and without a trailing slash, so grouping raw labels silently splits one
page into several. Surfaced via the spider2-autofix loop (Codex runner, round r2);
FAIR_PRODUCT (adversary-screened, restatable from URL-path semantics + page-grain
question wording + solver-observed distinct values, no gold dependency). The rule
fired mechanism-aligned on both targets; flipped local330 (landing/exit page counts),
local331 residual is a separate sequence-semantics axis beyond canonicalization.

* skill(analytics): iter6 — coverage over a selected group is a set-membership aggregate

When a question first selects a group of entities ("the top 5 actors", "these
products") and then asks what count/share/percentage of a DIFFERENT subject domain
relates to *these* selected entities ("what % of customers rented films featuring
these actors"), the subject set is the UNION across the whole group: count DISTINCT
subject ids once across the selected entities and return one collective value at the
subject-domain grain — not one row per selected entity (which double-counts subjects
related to more than one entity and answers a different question). Narrowly guarded:
emit one row per entity only when the wording says "for each / per / by / list" or
asks for each entity's own metric ("top 5 players and their batting averages").

The collective-coverage cousin of the existing per-entity selected-set rule. Generic
analytics craft (per-entity metric vs set-level coverage). Surfaced via the
spider2-autofix loop (Codex runner, round r3); FAIR_PRODUCT (adversary-screened,
restatable from wording alone, no gold dependency). Flipped local195 mechanism-aligned
(union COUNT(DISTINCT customer)/total, one scalar); 0 regression across 5 passing
per-entity top-N guards (local023/024/029/212/221 stayed long).

* skill(analytics): label-only joins must LEFT JOIN — incomplete dims silently drop fact rows

Mirror of the existing fan-out rule for the DROP direction: an inner JOIN to a
dimension table used only to attach a display attribute silently discards every
fact row whose key has no parent when the dimension is incomplete (trimmed
catalogs, late-arriving / SCD-gap rows), shrinking counts/sums and the universe
over which shares/averages/medians are computed. Guidance: LEFT JOIN pure
enrichment; inner-join a dimension only when intended as a filter; key the
aggregate/GROUP BY on the fact column, not the dimension column.

Spider2 autofix round 'joindim': flips complex_oracle local050 (FAIL->PASS,
official scorer) — solver dropped the gratuitous products inner-join and
recovered the exact gold. local060/063 also adopt LEFT JOIN (rule fires) but
remain gold-convention-blocked. Guards local061/067 held.

* docs(spider2-specs): add todo/17 — lifecycle-event metrics (semantic-layer)

Draft intake spec surfaced by the spider2-autofix loop (round r1): the model-layer
form of the shipped iter4 lifecycle-date-anchoring skill rule — infer per-state
lifecycle-event metrics (e.g. delivered_orders with defaultTimeDimension = the
delivery timestamp) during enrichment so the correct time anchor is the default for
any consumer, not only an agent that loaded the skill. Generic; FAIR_PRODUCT.

* fix(connectors): accept leading underscore in connection/identifier ids

The safe-identifier validator regex /^[a-zA-Z0-9][a-zA-Z0-9_-]*$/ allowed an
underscore everywhere except the first character, so a connection id / database
name that legitimately starts with '_' (valid in Snowflake, e.g. _1000_GENOMES)
could never be ingested or queried. Allow a leading underscore across all 16
duplicated validators (connection ids, source ids, page/wiki keys, warehouse-
verification tool schemas). Path-safety is unaffected — '.' and '/' remain
excluded, and assertSafePathToken still blocks traversal.

* feat(analytics): generic geospatial query guidance

Add a Snowflake ST_* dialect note (ST_MAKEPOINT lon-first, ST_DWITHIN/ST_CONTAINS/
ST_WITHIN/ST_INTERSECTS, bbox->polygon via ST_MAKEPOLYGON/ST_MAKELINE) and a
dialect-agnostic 'Spatial predicates' recipe in the analytics skill (resolve the
entity geometry, build an area-of-interest polygon, test with the engine's
containment/proximity/overlap predicate; mind lon/lat argument order). Steers the
solver off hand-rolled lat/lon BETWEEN boxes toward correct, index-assisted
geospatial predicates.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(analytics): parse code/dependency text by language grammar

Add two generic <sql_craft> rules: (1) parse imported/required/loaded packages by
the language or manifest format (Java import keep-package-path allowing underscores/
mixed-case; Python import/from + alias stripping; R library/require; .ipynb parse
JSON cell source before language rules; JSON manifests flatten the dependency object
keys), stripping comments/prose and splitting multi-import lines; (2) on a
de-duplicated table with a documented copy/occurrence count, choose COUNT(*) vs the
weight column from the population the question names, not silently. Steers off one
broad regex that drops valid identifiers and matches prose.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(analytics): source filters/dates/measures from the owning fact grain

Add a <sql_craft> rule for joined fact tables at different grains (parent order
vs child line item): read each predicate, calendar bucket, and measure from the
table whose grain the question names, not whichever is in scope post-join. An
order-grain filter ("orders that are Complete", "the order's creation date")
must come from the parent even though the child carries its own status/created_at;
line price/cost come from the child. Mirror at metric grain: don't combine a
parent-grain count with child rows (num_of_item * SUM(line_price) per line) —
aggregate each measure at its own grain before combining.

* feat(analytics): collapse multi-valued classes to one representative per entity before counting/concentration

When an entity carries a multi-valued classification array (IPC/CPC codes, tags)
and the methodology counts entities-per-class or a concentration/diversity metric
(HHI, originality, share), pick ONE representative per entity first (the array's
main/primary/first flag, else a defined fallback like most-frequent), then
aggregate; and use COUNT(DISTINCT entity) when the denominator is defined as a
count of entities. Unnesting the array otherwise multiplies an entity's weight by
its code count, inflating per-class frequencies and skewing the ranking/score.

* feat(connectors): introspect BigQuery datasets hosted in foreign projects

A dataset_ids/dataset_id entry may now be written `project.dataset` to
introspect a dataset hosted in another project while query jobs still bill to
credentials.project_id. Entries are parsed once at the config boundary into
canonical {project, dataset} pairs; introspection, primary-key discovery,
testConnection, getTableRowCount, and listTables (grouped per project) all
resolve in the dataset's own project, and scanned tables are labeled with that
project so sampling, distinct-value, and read queries resolve. Bare entries are
unchanged.

Implements spider2-specs/specs/18-bigquery-cross-project-datasets.md.

* feat(scan): durable, resumable, bounded relationship detection during enrichment

Move the enrichment persistence boundary to the cost boundary and bound the
open-ended relationship stage (spec 19).

- Checkpoint descriptions + embeddings into the queryable `_schema` manifest
  (and the raw enrichment artifacts) before relationship detection runs, via a
  new `onCheckpoint` hook + `writeLocalScanEnrichmentCheckpoint`. An interrupted,
  budget-truncated, or failed relationship stage now degrades to "no joins",
  never "no descriptions".
- Resume the enrichment cache by content identity: re-key the SQLite stage store
  on `(connection_id, stage, input_hash)` so a re-run with a fresh runId resumes
  finished descriptions/embeddings instead of re-paying for LLM work. The
  disposable cache recreates its table if the on-disk key shape differs.
- Make the relationship stage observable and bounded: a sticky wall-clock budget
  (`scan.relationships.detectionBudgetMs`, default 600000 ms) + per-unit progress
  + honored `ctx.signal`, threaded through profiling, validation, and composite
  detection. On exhaustion/abort it stops scheduling, finalizes, and returns a
  partial result instead of throwing or hanging.
- Mark a budget/abort-truncated result partial (diagnostics `partial`/`partialReason`
  + recoverable `relationship_detection_partial` warning). A graceful partial saves
  as a completed stage and resumes cheaply; raising the budget changes inputHash
  and forces a fresh, fuller run. A process killed mid-stage saves nothing.

Document `detectionBudgetMs` in the ktx.yaml reference. Append implementation
notes to specs/19 and move the intake draft to done/.

Also carries the in-tree per-table enrichment LLM timeout work it builds on
(`description-generation.ts` + the `enrichment_timeout` warning code), which is
intertwined in `local-enrichment.ts`/`types.ts` and cannot be split into a
separately-building commit.

* feat(scan): bound + retry the per-table enrichment LLM call

The batched table-description call had no retry (sampleTable retried 3x, this did
not), so a single transient backend error (e.g. an overloaded/burst rejection when
many tables enrich concurrently) silently nulled a whole table's descriptions —
observed dropping ~70% of a db's tables during a bad window despite ample quota.

- Wrap generateObject in retryAsync (3 attempts + backoff; KTX_ENRICH_LLM_ATTEMPTS).
- Fresh per-attempt timeout (KTX_ENRICH_LLM_TIMEOUT_MS, default 120s) still bounds a
  wedged wide table; a timeout is surfaced as KtxAbortedError so it is NOT retried
  (one wedge stays one timeout, not 3x).
- Granular per-table progress + start/done/retry/timeout logging.

Composes with spec 19 (its non-goal #1): spec 19 makes completed descriptions durable;
this makes more of them complete.

* feat(scan): survive a hung LLM enrichment backend and resume descriptions

Two compounding failure modes on the per-table description-enrichment path (spec 20):

Enforced per-table timeout for subprocess backends. The runtime declares whether it owns an SDK subprocess (subprocessForkSpec on KtxLlmRuntimePort); codex/claude-code calls run behind a ktx-owned detached child that is tree-killed (SIGKILL of the process group on POSIX, taskkill /T on Windows) on the deadline or ctx.signal, reaping the wedged model grandchild. HTTP backends keep native fetch abort. Default stays 120s, one-wedge-one-timeout.

Incremental, resumable descriptions persistence. generateDescriptions flushes enriched tables per batch to an inputHash-tagged durable record (at a stable, non-syncId path) plus only the changed manifest shards, skips already-enriched tables on resume, and never lets one table's failure discard the stage (a skipped table costs one missing description, not the whole stage's output).

Spec 20 refined + intake draft moved to done/.

* feat(scan): selective enrichment stages (--stages) + per-stage cache keys

Split the single coarse enrichment cache key into per-stage hashes
(descriptions <- snapshot + LLM identity; embeddings <- snapshot + embedding
identity + description digest; relationships <- snapshot + relationship settings
+ LLM identity), so changing one stage's inputs invalidates only that stage and
never throws away the expensive per-table descriptions on an unrelated edit.

Add `ktx ingest --stages <list>` to force-re-run a chosen subset on an
already-ingested connection: a named stage bypasses the completed-stage
short-circuit while the per-table descriptions resume record still skips
already-enriched tables, and unselected stages are left untouched on disk. Feed
embeddings + relationships their description context from the on-disk _schema
when descriptions do not run this invocation, and carry descriptions into the
llmProposals evidence packet (closing a latent gap on the full-run path too).
Surface an enrichment_stage_stale warning when an unselected stage's inputs have
drifted, rather than silently cascading the work.

Implements spider2-specs/specs/21-selective-enrichment-stages.md.

* test(analytics): realign SKILL.md acceptance test with the evolved skill

Three assertions in analytics-skill-content.test.ts drifted from the analytics
SKILL.md as later iterations edited the skill without updating the test:

- the sub-heading was renamed Window functions -> Ordering & aggregation
  determinism (iter2), so follow the source name;
- the rule "Expose identity, not just the label" was renamed to "Project BOTH
  identity and label" (spec 14), so match the new wording;
- the dialect-FQTN guard false-positived on the Java package example
  com.planet_ink.coffee_mud, whose backticks made a 3-segment package path read
  as a BigQuery/Snowflake `a.b.c` table reference. Drop the backticks so the
  guard stays at full strength without weakening it.

* fix(scan): --stages subset must not delete unselected stages' on-disk artifacts

A --stages subset that omitted descriptions wiped all on-disk ai/db descriptions
from the written _schema. runLocalScan writes the structural manifest shard from
the bare snapshot BEFORE enrichment runs, and the shard merge treats ai/db as
scan-managed and overwrites them with whatever the run emits — none, on a subset
that skips descriptions. Enrichment then read the already-wiped shard via
loadPriorDescriptions and had nothing to restore.

runLocalScanEnrichment now returns the best-available descriptions (fresh-this-run
if descriptions ran, else loaded from the on-disk _schema) instead of [], and
runLocalScan captures the prior descriptions before the structural write and feeds
them to both the structural write and enrichment, so an unselected stage's
artifacts survive. Joins were already preserved for --stages descriptions via the
manual/inferred preservedJoins path.

Tests: a full runLocalScan --stages relationships path test (RED without the fix,
GREEN with it — the earlier unit test missed the structural-pre-write ordering),
plus enrichment-layer contract tests for both directions. Validated live on
northwind: --stages relationships keeps all 110 descriptions + 22 joins (was
wiping to 0); --stages descriptions restores descriptions from the spec-20 resume
record (no LLM calls) while keeping joins.

* feat(dialects): bigquery nested-data (ARRAY/STRUCT/UNNEST), geospatial (GEOGRAPHY), SAFE_DIVIDE

bigquery.md lacked the two sections that define BigQuery analytics (present in snowflake.md):
- Nested & repeated data: UNNEST to flatten arrays of STRUCTs (GA360 hits, GA4 event_params),
  dot-notation field access, key-value param scalar-subquery extraction, fan-out/COUNT(DISTINCT) guard.
- Geospatial (GEOGRAPHY): ST_GEOGPOINT (lon-first), containment/proximity/distance/intersection
  predicates, areal allocation via ST_AREA(ST_INTERSECTION()).
- SAFE_DIVIDE for zero-denominator-safe rates; sharded-table shard-presence note.
Generic BigQuery craft surfaced by sql_dialect_notes; product-completeness (any BQ analyst benefits).

* feat(dialects): sqlite ROUND half-up FP-underflow note (+1e-9 before ROUND)

SQLite ROUND(x,n) rounds half-away-from-zero, but binary FP stores an exact
half-way value just below it, so ROUND(6.475,2) returns 6.47 not 6.48. Add a
dialect note: nudge by a tiny epsilon (1e-9) below display precision before
rounding for deterministic half-up, leaving non-boundary values unchanged.
Generic SQLite craft surfaced by sql_dialect_notes (any analyst rounding a

* docs(analytics): list-as-delimited-string, answer-literally, drop free-text columns

Add SKILL.md guidance to emit list-valued answer cells as delimited
STRING (not ARRAY/repeated column), answer the literal ask without
unrequested transformations (HAVING for aggregate bounds), and avoid
projecting unrequested free-text columns that corrupt row-delimited output.

* fix(scan,mcp): gitignore runtime logs, budget-guard LLM proposal, validate enrich timeout

- gitignore `.ktx/logs/` in both scaffold + setup-merge lists: the managed MCP
  daemon writes raw tool params (SQL, memory_ingest content) to mcp.log under a
  version-controlled `.ktx/`, and snowflake.log already sat there unprotected.
- gate the LLM relationship proposal on the detection budget/abort signal so an
  exhausted or aborted stage cannot start a fresh LLM call; document the boundary.
- validate KTX_ENRICH_LLM_TIMEOUT_MS (NaN/0 → 120s default) like enrichAttempts,
  so a bad value no longer times out every table immediately.
- daemon introspection now warns on malformed column/FK rows instead of dropping
  them silently, matching the table-row path and the "surface broken objects" goal.
- docs: document `ktx wiki -c/--connection`; fix the SQLite query-deadline schema
  doc (forked-subprocess SIGKILL, not worker-thread termination).

* fix(scan,wiki,mcp): address PR #312 review findings

- scan: key the description pipeline (resume map, enriched-schema and
  embedding-text lookups, manifest write/read) by full table identity via
  tableRefKey/buildTableRef, so two same-named tables in different schemas no
  longer cross-assign descriptions or skip a sibling on resume
- scan: re-throw a genuine context cancel during the batched description LLM
  call so Ctrl-C resumes the stage instead of nulling tables and recording it
  completed; per-table timeouts still degrade (context.signal not aborted)
- scan: report statisticalValidation 'skipped' (not 'completed') when a
  budget/abort stop leaves relationship profiling partial
- wiki: sync the full page corpus into the sqlite index and filter only the
  candidate/result set, so a connection-scoped search no longer prunes other
  connections' pages and cached embeddings from the shared index
- wiki: route verbatim ingest through the canonical writePageAndSync so
  contentHash is set and later syncs can short-circuit
- mcp: drop the as-unknown-as cast in serializeMcpError
- dialects/analytics: document the integer-division trap on postgres/sqlite/tsql

Adds regression tests for each behavior change.

* fix(wiki): scope connection filter before SQLite lane limit

Connection-scoped wiki search applied the connectionId allowlist after
the lexical/semantic lanes had already truncated to laneCandidatePoolLimit
over the full (connection-agnostic) corpus. When the requested connection
was a minority of a large corpus, its pages were crowded out of the
candidate pool before filtering, so a semantic-only match could be missed
outright and lexical hits under-ranked.

Push the path allowlist into searchLexicalCandidates/searchSemanticCandidates
so LIMIT applies to in-scope rows, matching what the token lane already did,
and drop the now-redundant post-limit JS filters.

fix(cli): isolate ktx-owned project repositories (#283)
* fix(cli): isolate ktx project git repos

* fix(cli): remove inert auto commit config

* test(cli): drop stale auto commit fixtures

* docs: document isolated ktx project repos

* test(cli): keep stale config grep clean

* fix(cli): guide setup away from foreign repos at the project dir

ktx owns the git repo rooted at the project dir and refuses to adopt one it
did not create (the Finding 3 isolation invariant). But setup steered users
straight into that failure: the interactive menu offers "Current directory"
first, and `--no-input --yes --project-dir <repo-root>` created directly in
place — both then threw a generic "Failed to initialize git repository:"
wrapper from deep in GitService.initialize().

Extract the ownership rule into a shared `classifyKtxRepoOwnership(dir)` used by
both GitService.initialize() (the invariant) and the setup wizard (pre-flight
guidance), so the decision derives from one rule. Setup now detects a foreign
repo before constructing GitService and: interactively re-prompts (the user
picks the existing `ktx-project` subfolder), or non-interactively returns a
clean missing-input with the actionable message. The typed foreign-repo error
is also surfaced verbatim instead of being buried under the generic wrapper.

Empty/non-repo current directories still work — only foreign repos are blocked.

* fix(cli): keep classifyKtxRepoOwnership total for non-directory paths

The setup ownership guard runs before the existing not-a-directory check, so
pointing a custom/--project-dir path at a file made classifyKtxRepoOwnership
lstat `<file>/.git`, hit ENOTDIR, and throw — crashing the setup step instead
of returning the friendly "path exists and is not a directory" result.

A path that is a file (or missing) holds no git repo for ktx to avoid, so treat
ENOTDIR like ENOENT and return 'unowned'. The downstream existingFolderState
check still rejects a non-directory with its friendly message, and the
classifier no longer throws raw errno for any caller.

fix(cli): classify ktx setup abandonment as aborted, not a blank error (#278)
* fix(cli): classify ktx setup abandonment as aborted, not a blank error

ktx setup returned a non-zero exit code without throwing when a user
abandoned the interactive wizard, so the command telemetry recorded
outcome=error with no errorClass/errorDetail — an unactionable blank in
the errors dashboard, where most ktx setup "errors" were really people
backing out of the wizard.

Add annotateCommandOutcome() to the command span so the setup flow (the
decision-maker) records the true outcome: genuine step failures and
--no-input missing input become outcome=error with a self-diagnosing
reason, while interactive abandonment and project cancellation become
outcome=aborted and drop out of the error view.

Unify the exit code and telemetry through setupTerminalOutcome() so they
can never diverge: aborts now exit 0 (matching the entry-menu Exit,
project cancel, and a confirmed Ctrl+C), while failures and automation
errors still exit 1.

* fix(cli): treat non-TTY setup missing-input as an error, not an abort

setupTerminalOutcome classified `missing-input` by `args.inputMode`, but
`auto` only means "interactive if a TTY is attached". A piped/CI `ktx
setup` without `--no-input` and without `--yes` is still `auto`, yet the
project and agents steps return `missing-input` there without ever
prompting (e.g. "pass --yes to create a project outside an interactive
terminal"). Classifying that as `aborted` made a broken automation run
exit 0 — a silent failure.

Key the classification off actual interactivity instead: input enabled
AND `io.stdout.isTTY === true`. Non-interactive missing-input now exits
1 with a `KtxSetupMissingInput` reason; only a genuine interactive abort
exits 0. Adds a non-TTY regression test and fixes the abandonment test
to use a real TTY.

feat(cli): add ingest LLM rate-limit governor with paced retries (#261)
* feat(cli): add ingest rate limit governor

* feat(cli): wire ingest rate-limit config

* feat(cli): report provider rate-limit signals

* feat(cli): show ingest rate-limit waits

* fix(cli): complete rate-limit event coverage

* fix(cli): abort ingest provider calls cleanly

* fix(cli): reject pre-aborted ingest rate-limit waits

* fix(cli): honor Claude rate-limit reset waits

* fix(cli): retry thrown Codex rate-limit failures

* fix(cli): type Claude rate-limit result details

* fix(cli): emit ingest rate-limit countdowns from rejected signals

* fix(cli): report ai sdk rate-limit header utilization

* fix(cli): gate LLM rate-limit retries on the governor budget

The AI SDK and Codex runtimes retried 429 / opaque rate-limit failures up
to 6-7 times with no backoff when constructed without a RateLimitGovernor
(scan, memory, setup) or with pacing disabled, ignoring Retry-After and
worsening the limit. The outer retry loop only cooperates with the
governor's pause, so without active pacing there is no backoff to apply.

Route the retry bound through a single source: RateLimitGovernor
.maxRetryAttempts(), which returns retry.maxAttempts when enabled and 1
(no outer retry) when absent or disabled. All three runtimes (ai-sdk,
codex, claude-code) now use it, so ingest.rateLimit.retry.maxAttempts
genuinely controls attempts and the hard-coded 6 (plus Codex's off-by-one
extra attempt) is gone. Backend-native retry (e.g. the AI SDK's maxRetries)
still handles transient 429s.

Also correct the ktx.yaml docs for maxWaitMs (caps each wait, not the whole
run) and maxAttempts, and sync uv.lock ktx-sl/ktx-daemon to 0.9.0.

feat(setup): wizard prompt tweaks and quieter query-history filter output (#259)
Setup wizard flow tweaks:
- Add a reveal-tail password prompt (reveal-password-prompt.ts) that unmasks
  the last few characters of a typed/pasted secret, and wire it into the setup
  prompt adapter in place of clack's password(); adds the @clack/core dep.
- Reorder wizard select options: surface "Paste a key" before the
  environment-variable option across embeddings/models/sources, promote
  Metabase/Notion in the source list, put Git URL before Local path, reorder
  the Notion crawl-mode choices, and relabel the sources "Done" action.

Query-history filter picker output:
- Collapse the per-template parse-failure lines into a single count in the
  setup output and route the full template-id list to --debug stderr.
- Model parse failures as a structured parseFailedTemplateIds field instead of
  warning strings.
- Add a privacy-safe query_history_filter_completed telemetry event
  (counts/enums only), mirrored into the Python daemon schema.

cb6a67c2d7 Make telemetry reliable across interrupts and headless installs
Three reliability gaps surfaced while auditing why PostHog numbers were
untrustworthy:

1. Interrupted commands lost their events. capture() is fire-and-forget and the
   only flush guarantee lived in a finally block, which SIGINT/SIGTERM skip — so
   Ctrl-C'ing a long ingest or an MCP client killing 'ktx mcp stdio' dropped the
   command event and any queued events. Add SIGINT/SIGTERM handlers (real-process
   entry only; never under test/programmatic io) that mark the active command
   span aborted, emit it, drain the emitter, then exit. Idempotent with the
   normal finally path via the single-consume command span.

2. Headless-first installs were invisible. loadTelemetryIdentity refused to mint
   an installId unless stdout was a TTY, so a machine whose first run was an
   IDE-launched MCP server or a script emitted nothing, ever. Mint on first run
   regardless of surface (still honoring CI/DO_NOT_TRACK/KTX_TELEMETRY_DISABLED),
   writing the one-time notice to stderr — safe under the MCP stdio protocol,
   which reserves stdout. Drop the now-unused stdoutIsTTY option.

3. No guard against silent emit regressions (the 0.7.0 scan_completed blackout).
   Add tests: the shared executePublicIngestTarget chokepoint emits exactly one
   ingest_completed on success and on the preflight-failure branch, and a
   database target invokes the scan that emits scan_completed; plus coverage for
   the aborted-flush helper.

Identity is unchanged otherwise: every event still attributes to the installId
in ~/.ktx/telemetry.json. No event/field changes, so Node<->Python schema parity
is untouched. Docs updated to reflect first-run-on-any-surface activation.

feat(cli): profile ingest runs and split model vs tool time (#249)
* feat(cli): profile ingest runs to find where wall-clock time goes

Add opt-in profiling for `ktx ingest`. Each timed phase, work unit, and
agent loop now records durationMs / step count / token usage in the
trace, and a post-run aggregator rolls them up into a "where did the
time go" report printed to stderr.

Enable per run with KTX_PROFILE_INGEST (1/true -> human table, json ->
raw structured profile) or persistently via `ingest.profile` in
ktx.yaml. The json form emits raw milliseconds, token counts, and a
summary.headline one-line diagnosis so coding agents can parse it
directly; json wins when both env and config request profiling.

- runtime-port: RunLoopMetrics (totalMs, usage, stepCount,
  stepBoundariesMs) plus onMetrics callbacks on text/object generation
- ai-sdk + claude-code runtimes: capture per-loop timing and token usage
- work-unit-executor and stages 3/4: thread metrics into trace events
- ingest-bundle.runner: time worktree / triage / clustering / index /
  reconcile / squash phases and emit the profile in a finally block
  (best-effort; never affects the run outcome)
- ingest-profile: new trace+transcript aggregator with table/json formatters
- config: ingest.profile flag; docs: profiling section in ktx-ingest.mdx

* fix(cli): flush tool-call logs before reading ingest profile

Tool transcripts are appended fire-and-forget so the agent hot path never
blocks on logging. The ingest profiler read them before the writes settled,
so per-work-unit toolMs (and the model-vs-tool split derived from it) could
be incomplete. Track in-flight appends and expose flushToolCallLogs() —
bounded by a timeout so it can never hang — and flush before the profiler
reads the transcript.

Extract errorMessage, writePrefixedLines, and flushPrefixedBufferedCommandOutput
into clack.ts so the setup wizard, managed daemons, and embedding/agent steps
share one rail-formatted writer. setup-databases.ts also adds a
"disable query history and retry" option when the schema-context build fails
and query history is the likely culprit, surfaced via a new
failed-query-history-unavailable status.

* fix(cli): carry catalog through the picker so BigQuery/Snowflake/SQL Server scope filters match

The setup picker's KtxTableListEntry was a 2-level { schema, name }, so
qualifiedTableId always wrote db.name into enabled_tables. When BigQuery,
Snowflake, or SQL Server later ran fast ingest, their introspect step filtered
the scope set with scopedTableNames(scope, { catalog: projectId|database, db })
— catalog was non-null on the introspect side but null in the scope refs, so
every entry was rejected, the live-database adapter staged zero table files,
and detect() failed with 'Adapter "live-database" did not recognize fetched
source output'.

Align the picker boundary with the canonical 3-level KtxTableRef:

- Add catalog: string | null to KtxTableListEntry.
- BigQuery/Snowflake/SQL Server listTables populate catalog from the
  resolved projectId / database; Postgres/MySQL/ClickHouse/SQLite set null.
- qualifiedTableId emits catalog.schema.name when catalog is non-null
  (resolveEnabledTables already accepts the 3-part shape) and
  schemasFromEnabledTables now goes through parseDottedTableEntry so it
  recovers the schema correctly from both 2-part and 3-part entries.
- Export parseDottedTableEntry from enabled-tables.ts (@internal) for picker
  reuse.

Update listTables expectations in all seven connector tests and the setup /
picker test fixtures. Add a picker regression test that covers the
catalog-bearing round-trip (save + refine).
