## Summary
Brings the Keboola connector to feature parity with the legacy internal data-analyst's per-table sync strategies. Closes the four documented gaps from the spec branch (`zs/keboola-connector-specs`):
- **Typed parquet** in the legacy SDK extraction path — column types from Keboola Storage metadata (provider cascade `user > ai-metadata-enrichment > keboola.snowflake-transformation`) survive the CSV → parquet roundtrip; invalid date strings (`'0000-00-00'`) and invalid numeric strings (`'Non-Manager'`) become NULL while keeping the column's typed schema. Pre-fix everything was VARCHAR.
- **Incremental sync** via Storage API `changedSince` — opt-in per table; pulls only delta rows, merges into the existing parquet by `primary_key` (drop_duplicates with keep='last'). Cuts daily extraction from O(full table) to O(delta).
- **Partitioned sync** — flat per-partition layout `data/<table>/<key>.parquet` (e.g. `2026_05.parquet`), per-affected-partition merge for daily updates, chunked initial load with 1-day overlap and 2-empty-chunk stop heuristic.
- **`where_filters`** — server-side row filter with date placeholders (`{{today}}`, `{{last_3_months}}`, `{{start_of_3_months_ago}}`, etc.) resolved at sync time. Force the SDK path; reject `incremental + where_filters` combination at API layer (changedSince already filters temporally).
## Architecture
- **Schema migration v25 → v26**: 7 new columns on `table_registry`. Existing `sync_strategy` column reused (pre-v26 it was inert catalog metadata; post-v26 the extractor dispatches off it).
- **Per-table dispatcher** in `extractor.run()` routes to one of `_extract_via_extension` (full_refresh + extension), `_extract_via_legacy` (full_refresh + filters or extension fallback), `extract_incremental`, or `extract_partitioned`.
- **API conflict policy**: `incremental + where_filters` → 422; `partitioned + query_mode='remote'` → 422; `partitioned ⇒ partition_by required`.
- **Admin UI**: third "Direct extract (Storage API)" radio in the Keboola Register / Edit modals, alongside existing "Whole table (extension)" and "Custom SQL". When selected, exposes a v26 sync-strategy panel with conditional fields per strategy.
## Test plan
- [x] **Unit + module** — 134 v26 tests covering migration, repo, parquet_io, where_filters, incremental (compute_changed_since + merge_parquet + extract_incremental E2E), partitioned (key derivation + merge_partition + chunked windows + extract_partitioned E2E), extractor dispatcher, admin API validators, PUT field clearing, registry-shape → dispatcher bridge
- [x] **HTML form structure** — all v26 inputs + visibility classes + JS payload fields verified in rendered template
- [x] **Real Keboola roundtrip** — registered a small test table as `sync_strategy='incremental'` against a test Storage project, triggered two syncs:
- Sync 1: `changedSince=None` → full pull → 9 rows typed parquet
- Sync 2: `changedSince=last_sync - 1d window` → 9 delta rows merged with 9 existing → 9 after dedup on primary_key (PK merge confirmed)
- [x] **Browser UX** — agent-browser session against a local uvicorn: login → admin/tables → register modal → switch radios → verify field visibility per strategy → submit → edit existing row → switch to Direct/Incremental → save → confirm DB persistence
- [x] **Regression** — no regressions in the broader 3252-test suite (3 pre-v26 tests updated for the deprecation-marker removal + schema-version bump; 2 pre-existing environment-sensitive test failures unrelated to this change)
## Bugs caught + fixed during E2E
The browser + real-Keboola roundtrip exposed four bugs the unit tests missed:
1. **JS visibility race** — two competing `forEach` loops set `display=''` then `display='none'` on form elements sharing `kb-strategy-incremental kb-strategy-partitioned` classes (window_days + max_history_days are reused across strategies). Fix: single-pass selector with class-based visibility resolver.
2. **PUT cannot clear field** — pre-v26 `updates = {k: v ... if v is not None}` collapsed "omitted from body" and "sent as null" into the same case, so admin couldn't switch a partitioned row back to full_refresh and have stale `partition_by` clear. Fix: `model_dump(exclude_unset=True)`.
3. **Subprocess DB lock conflict** — `_read_last_sync` reopened `system.duckdb` while the parent server held the write lock (subprocess contract at `app/api/sync.py:_run_sync` line 260). Fix: parent injects `__last_sync__` into table_config before subprocess spawn.
4. **Wrong KBC table_id** — `extract_incremental` / `extract_partitioned` built the Storage API table_id from the registry row's slugified `id` (`circle_inc`) instead of `bucket.source_table` (`in.c-finance.circle`), producing 404s. Fix: prefer `bucket+source_table`; fall back to `id` only when bucket empty.
## Operator notes
- Existing tables stay on `full_refresh` after migration; admins opt individual tables in via `agnes admin register-table --sync-strategy ...`, the Keboola Edit modal, or `POST/PUT /api/admin/registry`.
- `merge_parquet` and `merge_partition` use `pd.concat + drop_duplicates`, loading both existing and delta into pandas RAM. For tables in the multi-million-row range this may OOM — switch to `partitioned` strategy for those (per-partition merge keeps memory bounded). Documented in `### Internal` of the changelog entry.
- Date placeholders are resolved at **sync time**, not register time — a typo'd `{{lasst_week}}` is accepted at register and surfaces only when the next sync runs. By design (rolling windows need late-binding).
## Spec source
The four corresponding plans on the `zs/keboola-connector-specs` branch under `docs/superpowers/plans/2026-05-07-0[1-4]-*.md` capture the design rationale and link back to internal repo references for each subsystem.

## Summary
Verified against production: `claude -p` headless mode doesn't fire SessionEnd hooks (proven via `--output-format stream-json --include-hook-events`: zero `SessionEnd` events), so any session JSONLs from `-p` invocations stay orphaned locally and never reach the server. Fix: add `agnes push --quiet` as a third SessionStart entry — symmetric self-heal alongside the existing `agnes pull` entry. Existing workspaces pick this up on their next `agnes init` via the marker-based migration already in `cli/lib/hooks.py`.
Separately: a colleague's fresh install showed `agnes diagnose` warning "uploads are not being processed", which led them to suspect their `agnes push` was broken. The warning is actually about the LLM-based `verification-detector` backlog (uploads themselves were arriving fine — confirmed by 23+3 JSONLs landed on the server while the warning was firing). Reword the warning to "verification-detector backlog" + add `last_processed` to the diagnose dict so operators don't have to grep logs to confirm.
## Test plan
- [x] `pytest tests/test_lib_hooks.py` — updated count + added `agnes push in SessionStart` assertion.
- [x] `pytest tests/test_setup_hooks_template.py` — updated.
- [x] `pytest tests/test_clean_install_integration.py` — updated.
- [x] `pytest tests/test_health_session_pipeline.py` — updated warning text + asserted `last_processed` field.

Operator-and-analyst quality bundle: a security fix for the optional
Telegram bot, two CLI gaps closed, and three rounds of UX polish on
`agnes diagnose` and `agnes pull` so non-TTY consumers (CI runners,
Claude Code SessionStart hooks, sub-agent watchdogs) get readable,
actionable signal.
- Pairing-code RNG: random.choices -> secrets.choice (CSPRNG).
- Telegram script runner: refuse out-of-shape usernames before sudo -u.
CLAUDE.md.bak.<ISO-timestamp> before regenerating.
- agnes admin unregister-table <id> -> DELETE /api/admin/registry/{id}
- agnes admin update-table <id> --field=value ... -> PUT /api/admin/registry/{id}
response but never promotes the headline. BQ billing-equals-data check
downgraded warning -> info.
default (5 s / 1 MiB vs 30 s / 10%) so sub-agent watchdogs don't kill
the pull as a hung process. New env knobs:
AGNES_PULL_PROGRESS_INTERVAL_{SECONDS,BYTES}.
--include-schema (or ?include=schema) to opt back in.
Tests: 120 passed across the touched modules, including new tests for
each fix. Pre-existing failures on main (DB migration v1->v9, binary
rename) are unrelated and not introduced here.
GET /api/health/detailed now returns a session_pipeline service entry.
Heuristic:
max(mtime of /data/user_sessions/**/*.jsonl) <=
max(processed_at in session_extraction_state) + grace_seconds
grace_seconds = 2 × verification-detector cadence (default 30 min;
configurable via SCHEDULER_VERIFICATION_DETECTOR_INTERVAL).
When the assert fails, status='warning' (never 'error') with an
actionable detail pointing at the verification-detector scheduler job.
A warning bubbles up to the existing overall='degraded' aggregation —
operators querying /api/health/detailed (or /agnes diagnose system)
get a clear breadcrumb instead of a silently-broken pipeline.
Cold-start case (no session files, or files newer than the grace
window with empty state table) is handled explicitly to avoid noise
on a fresh deploy.
Tests: tests/test_health_session_pipeline.py.
Devin's second review pass on commit 16938ae7 surfaced 2 more issues:
BUG_pr-review-job-58ae3148_0001 — non-BQ materialized via PUT bypasses source_query check
app/api/admin.py update_table only enforces 'query_mode=materialized
requires source_query' for source_type='bigquery' rows (via the
synthetic RegisterTableRequest at line 2129+). Non-BQ source types
(Keboola) skip the check — admin could PUT {query_mode: materialized}
on a Keboola local row without source_query, persist successfully,
then crash at the next sync tick when kb_materialize_query received
sql=None and DuckDB rejected COPY (None) TO '...'.
Fix: generic coherence guard before the BQ-specific block — for ALL
source types, query_mode='materialized' requires non-empty source_query
in the merged record. Returns 422 with a hint about reverting via
query_mode='local'/'remote'.
ANALYSIS_pr-review-job-642ff90f_0007 — diagnose returns 'ok' on BQ resolution failure
app/api/health.py:_check_bq_billing_project caught get_bq_access()
exceptions and returned status='ok' with a 'could not resolve' detail.
Automated alerting keyed on status != 'ok' would silently miss missing
google-cloud-bigquery, auth failures, or malformed config. Fix: return
status='unknown' on resolution failure — surfaces it on operator
dashboards without promoting the overall health to 'degraded' (which
'warning' does, intentionally for the billing==project case).
Tests:
- test_update_keboola_to_materialized_without_source_query_rejected:
PUT {query_mode: materialized} on a Keboola local row returns 422
with 'source_query' in the detail
- test_diagnose_returns_unknown_status_when_bq_resolution_fails:
when get_bq_access raises, the bq_config service entry surfaces
status='unknown' (not 'ok')
Full sweep: 2507 passed, 25 skipped, 0 failed (+2 from previous sweep
because of the 2 new regression tests; 8 pre-existing internal_roles
schema-migration failures still ignored per task brief).
Diagnostic + operator-facing documentation that closes the loop on the work in this PR.
`da diagnose` (via /api/health/detailed):
- New _check_bq_billing_project() helper. When data_source.type='bigquery' and BqProjects.billing == .data, surface a yellow warning: 'BigQuery billing project equals data project'. Hint includes the YAML field path + the /admin/server-config UI shortcut. Diagnose's overall status promotes warning → degraded so the CLI echoes it.
- Non-BQ instances (Keboola-only, etc.) skip the check.
- Implementation hooks into the existing /api/health/detailed surface — no new endpoint, no CLI changes.
config/instance.yaml.example documentation:
- data_source.bigquery.billing_project: USER_PROJECT_DENIED hint, /admin/server-config UI reference
- data_source.bigquery.legacy_wrap_views: analyst-side discipline note (use `da fetch` / `da query --remote`), issue #101 history, view-heavy deployment guidance
- data_source.bigquery.max_bytes_per_materialize: cost guardrail block (NEW — wasn't documented in .example before)
- ai.base_url: provider list + UI hint
- openmetadata + desktop: 'configurable via /admin/server-config UI' headers
- corporate_memory: leading note that the schema is editable via UI

- CHANGELOG.md: comprehensive Unreleased section
- CLAUDE.md: schema chain → v20 + Materialized SQL connector mode + per-connector tab UI mention
- README.md: mode-first source table summary
- docs/architecture.md: per-connector tab UI mention

Tests:
- test_diagnose_billing.py — 3 cases (BQ with billing==data warns, BQ with billing!=data clean, non-BQ skips)
* fix(security+ops): #82#85#87 — auth hardening, API validation, deploy posture
Security and operational hardening across three issue groups:
- M23: docker-compose.override.yml → docker-compose.dev.yml (BREAKING, prod foot-gun)
- C13: Container runs as non-root user 'agnes' (USER directive in Dockerfile)
- M21: Docker resource limits (mem_limit, cpus) on app + scheduler
- M22: Caddyfile security headers (X-Frame-Options, X-Content-Type-Options, Referrer-Policy, -Server)
- M17: /api/health split into minimal (unauth) + /api/health/detailed (auth) (BREAKING)
- M26: release.yml restricts build-and-push to main + workflow_dispatch; paths-ignore for docs
- C2: table_id traversal validation on /api/data/{table_id}/download
- M4: Upload streaming (chunk-read + temp file) instead of full-buffer; /local-md hashed filename
- C5: reset_token removed from POST /api/users/{id}/reset-password response
- C8: Startup WARNING when no user has password_hash (bootstrap window visible)
- M9: Audit log on failed web form login (mirrors /auth/token endpoint)
- M10: Atomic magic-link consume via compare-and-swap (CONSUMED: marker + DuckDB conflict catch)
Also: SSRF protection on /api/admin/configure (#46), memory stats SQL aggregation (#90)

* fix(review): SSRF 169.254.x.x + IPv6 multicast; M10 marker cleanup safety
Review fixes:
- Add 169.254.0.0/16 (link-local, cloud metadata) to SSRF regex — was
missing, allowing requests to AWS/GCP/Azure metadata endpoints
- Add ff[0-9a-f]{2}: (IPv6 multicast) to SSRF regex
- M10: wrap Step 3 (CONSUMED marker cleanup) in try-except with
warning log — prevents unhandled exception if DB write fails after
successful token consumption
- Add test for 169.254.169.254 SSRF rejection

* fix(review): SSRF IPv6 bypass, CLI health endpoint, upload FD leak
Address Devin Review findings on PR #104:
1. SSRF IPv6 bypass: Replace hostname regex with DNS resolution +
ipaddress module checks. The old regex patterns like `fe80:` only
matched up to the first colon, missing real IPv6 addresses like
`fe80::1`, `fc00::1`, `ff02::1`. The new approach resolves the
hostname via getaddrinfo and checks each resulting IP against
ipaddress.is_private/is_loopback/is_link_local/is_reserved/is_multicast.
2. CLI commands broken: `da setup test-connection`, `da setup verify`,
`da diagnose`, `da status` all called /api/health expecting the old
format (status=="healthy", services dict). Now they call
/api/health/detailed for service-level checks (with graceful fallback
to the minimal endpoint when auth is not configured).
3. Temp file handle leak: _stream_to_temp returns an open
NamedTemporaryFile; callers now close it before shutil.move() to
prevent FD leaks until GC.
Also adds IPv6 SSRF test cases (loopback, link-local, unique-local,
multicast) with mocked DNS resolution for test environment independence.

* fix(review): download regex blocks hyphenated IDs; document health split
Address Devin Review round-3 findings on PR #104:
1. _SAFE_IDENTIFIER regex blocked hyphenated table IDs: The download
endpoint used the strict SQL-identifier regex which does not allow
dots or hyphens, but Keboola table IDs like in.c-crm.orders
contain both. Switched to _SAFE_QUOTED_IDENTIFIER which allows dots
and hyphens while still blocking path-traversal chars (/, .., \)
and quote/control characters. Added test for hyphenated/dotted IDs.
2. Documented health endpoint split in DEPLOYMENT.md: Added Health
checks & external monitoring section explaining both endpoints
(minimal unauth /api/health vs authenticated /api/health/detailed)
and how to wire external monitoring tools to the detailed endpoint
with a PAT.

* release(0.12.1): cut hotfix for snapshot integrity + #82/#85/#87 hardening
* fix(security): apply CAS pattern to password reset confirm (#82/M10 follow-up)
Devin review on the rebased PR flagged the asymmetry: magic-link verify
got the atomic compare-and-swap pattern in the original M10 fix, but
password reset confirm at /auth/password/reset/confirm was still using
read-validate-clear. Two concurrent POSTs with the same valid reset
token could both succeed in setting different new passwords (last-write-
wins). Lower severity than the magic-link race because the attacker
would need the reset token AND to race the legitimate user, but the
asymmetry was a polish gap.
Mirrors app/auth/providers/email.py::_consume_token CAS exactly: write
unique CONSUMED:<random> marker via UPDATE...WHERE token=old_token, then
SELECT to verify our marker won, then proceed. Only the winner clears
the marker and applies the password change.
New regression test_concurrent_reset_only_one_wins in
tests/test_password_flows.py::TestResetConfirm pins the contract: two
ThreadPoolExecutor workers + Barrier hit /reset/confirm with the same
token; exactly one gets 302 (password applied), the other gets 200 with
'Invalid or expired'. Sanity-checked against the pre-CAS code — both
POSTs got 302 (race confirmed).

UI now shows a small footer badge with:
- release channel + CalVer version (e.g. 'stable-2026.04.47')
- floating image tag (e.g. 'stable')
- time since last container restart (proxy for 'last deployed')
Backend:
- app/api/health.py: /api/health returns image_tag, commit_sha, deployed_at
- app/api/health.py: new /api/version endpoint (lightweight, no DB hit, for
footer badge polling)
Infra:
- startup-script.sh.tpl: resolves image digest from ghcr pull, derives
channel + version from the tag name, and writes AGNES_VERSION /
RELEASE_CHANNEL / AGNES_COMMIT_SHA into .env so the app can surface them
to the UI.
UI:
- app/web/templates/base.html: footer loads /api/version asynchronously and
renders '<channel>-<version> · <tag> · deployed <relative> (<UTC>)'.
Tooltip shows full detail (commit sha, schema version).
