* Add /marketplace browse page + Model B opt-in stack composition
New /marketplace browse surface unifies the curated marketplaces
(admin-managed git mirrors) and the community Flea Market behind
three tabs — Curated / Flea / My Stack — with per-tab category
filter, search across both sources with scope checkboxes, and
numeric pagination, all driven by URL query state. Plugin detail
at /marketplace/curated/<slug>/<plugin> and /marketplace/flea/<id>;
nested skill / agent detail at /marketplace/curated/<slug>/<plugin>/
{skill,agent}/<name> and the flea-side single-page detail.
Model B opt-in: an RBAC grant on a curated plugin is now only
*eligibility*. The user must click "Add to my stack" for it to
enter their served Claude Code marketplace. Composition flips
from (rbac ∖ opt_outs) ∪ store_installs to
(rbac ∩ subscriptions) ∪ store_installs. The legacy
user_plugin_optouts table is renamed user_curated_subscriptions
(schema v27) — same table shape, inverted semantic, repository
methods become subscribe / unsubscribe / is_subscribed.
UX vocabulary: Install → Add to my stack, Installed → In your
stack, card "Installed" badge → "In stack" (amber pill), tab
"My Subscriptions" → "My Stack". Bridges the two-step model
(server-side bookmark vs. on-laptop install) the previous label
hid. Click triggers an inline post-add hint panel under the
description with the agnes refresh-marketplace recipe + Copy
chip, dismissible per-browser via localStorage.
Per-tab info blocks above the filter row:
- Curated: trust signal — "Each plugin here has a named curator
accountable for it." (blue accent + See-all-curators link)
- Flea: open-shelf signal — "Anyone in the company can upload
here." (purple accent + Tips-for-sharing link)
- My Stack: personal-shelf orientation — "Your AI stack —
everything you've added." (slate accent, no link)
Tabs carry per-tab Heroicons (shield-check / building-storefront
/ rectangle-stack) tinted to match each tab's accent; flips white
when the tab is active for contrast.
Hero illustration anchored to the right of the blue hero panel
(absolute, 47% wide, behind the search row content). Hidden
under 900px viewport.
Action-row CTAs realigned to publication intent: curated
"How to add new content" → "Submit a plugin" (links to the
guide page); flea button removed since +Upload sits next to it.
Empty-state CTAs match. /marketplace/guide/{curated,flea}
routes now host publication-flow guide pages with placeholder
ledes — full copy to be authored separately.
Categories: Heroicons-based icons mapped per category in
src/category_icons.py (zero new dependencies; SVG path strings
inlined). Marketplace cards, filter pills, and detail pages
read from the same source.
API endpoints under /api/marketplace:
- GET /items per-tab listing (curated / flea / my)
- GET /categories per-tab non-zero counts
- GET /curated/{slug}/{plugin} plugin detail
- POST/DELETE /curated/{slug}/{plugin}/install subscribe toggle
- GET /curated/{slug}/{plugin}/{skill,agent}/{name} inner item
The tab=my branch reads directly from
user_curated_subscriptions ∪ user_store_installs (not
resolve_user_marketplace, which bundles flea skills/agents into
a single store-bundle synthetic entry useful for serving the
Claude Code marketplace ZIP/git but wrong for browsing where
each item should appear as its own card).
Detail pages: plugin detail surfaces inner skills/agents as
clickable nested cards; commands/hooks/MCPs render as plain
name lists. Skill/agent detail mirrors the plugin layout with
kind-tinted accents (skill = green, agent = purple), Description
+ Details sidebar, Files + Docs sections, and the "How to call
it" copy-able invocation chip showing /<plugin>:<inner-name>
exactly as Claude Code namespaces it post-install. Curated
nested has no install button — links back to the parent plugin.
Navbar: standalone "My AI Stack" relabelled "My Stack" and
points at /marketplace?tab=my; "Store" link removed (Store
flow is reachable via the Flea Market tab's +Upload button).
The standalone /my-ai-stack and /store routes still work for
old bookmarks.
Tests cover the new browse / categories / install / RBAC paths
under tests/test_marketplace_api.py; existing marketplace and
store tests updated for Model B (explicit subscribe in fixtures).
Schema bumped v26 → v27 with idempotent migration that wipes
existing user_plugin_optouts rows on flip and adds
marketplace_plugins.created_at with registered_at backfill.
* Fix v28 migration + post-rebase test fallout
v28 ALTER TABLE marketplace_plugins ADD COLUMN created_at conflicted with
_SYSTEM_SCHEMA's earlier CREATE that already includes the column on fresh
installs (test fixtures starting at any pre-v28 version trip on it).
Switch to ADD COLUMN IF NOT EXISTS — same idiom as the upstream v27
Keboola sync-strategy migration on the same ladder.
Two test patches needed after the rebase bumped SCHEMA_VERSION 27 → 28:
- test_keboola_v27_migration.py: test_schema_version_constant_is_27 was
pinning ==27. Loosened to >=27 (the test's purpose is to verify the
v27 Keboola migration, not to pin the current SCHEMA_VERSION).
- test_setup_page_unified.py: was monkeypatching resolve_allowed_plugins
but compute_default_agent_prompt now reads from resolve_user_marketplace
(Model B-aware). Stub the right function so the test exercises the
v28 served-set path.
* Harden curated skill/agent inner endpoints against path traversal
`_read_inner`, the `skill_dir` walk in `curated_skill_detail`, and the
`agent_path.stat` in `curated_agent_detail` joined URL path-params onto
`plugin_root` without verifying the resolved candidate stayed inside it.
Starlette's `[^/]+` on `{skill_name}` / `{agent_name}` blocks the direct
URL exploit (encoded `/` 404s before the handler), but a curator-planted
symlink inside a curated marketplace's git mirror could still dereference
outside the plugin tree on read.
Adds `_safe_join(plugin_root, *parts)` doing
`Path.resolve(strict=True)` + `relative_to(plugin_root.resolve())`, used
by all three call sites so the boundary is enforced once and consistently.
Tests cover the helper directly (normal path resolves, escaping `..`
returns None, escaping symlink returns None, missing file returns None)
plus an end-to-end check that the symlink case actually 404s on the
HTTP endpoint. Symlink tests skip on Windows where symlink creation
needs elevated permissions; they run on Linux CI.

## 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.
