Opening a listing's detail sheet for >3s now passively marks it `seen`
and snapshots its current `total_price`. Seen listings are hidden from
the main list by default but automatically resurface when the price
changes (any direction). Distinct from `disliked` — explicit
like/dislike always overrides the passive seen state.
New "Hidden (N)" toggle on the FilterBar appears whenever at least one
listing is currently being hidden by the seen filter. Toggling it
reveals those rows in-place (without unmarking them) so the user can
review or explicitly clear via the existing Like/Dislike/Clear flow.
## Backend
- Alembic f7a8b9c0d1e2: `ALTER TABLE listingdecision ADD COLUMN
price_at_decision FLOAT NULL`.
- `models/decision.py`: ListingDecision gains nullable
`price_at_decision: float | None`.
- `services/decision_service.py`: adds `seen` to VALID_DECISIONS;
set_decision accepts an optional `price_at_decision`; it's only
forwarded to the repo for decision='seen' (other types null-out the
column to keep semantics clean).
- `repositories/decision_repository.py`: upsert_decision now carries
price_at_decision through the MySQL + SQLite upsert paths.
- `api/decision_routes.py`: SetDecisionRequest + DecisionResponse
expose the new field.
## Frontend
- `types/index.ts`: DecisionType = 'liked' | 'disliked' | 'seen';
ListingDecision gains `price_at_decision?: number | null`.
- `services/decisionService.ts`: setDecision sends the price only for
decision='seen' (and only when it's a finite number).
- `hooks/useDecisions.ts`: rewritten to store `Map<key, DecisionEntry>`
(decision + price snapshot). New `markSeen(id, price, type)` short-
circuits on existing liked/disliked. New `getDecisionEntry`,
`seenCount`.
- `App.tsx`: 3s `setTimeout` dwell timer fires markSeen when the
detail sheet stays open. Filter logic in `processedListingData`
hides `seen` rows whose `total_price === price_at_decision`, with
`showHidden` bypass. Computes `hiddenCount` to drive the toggle.
- `components/FilterBar.tsx`: new conditional "Hidden (N)" / "Showing
hidden (N)" toggle button (Eye / EyeOff lucide icons), surfaces only
when hiddenCount > 0.
## Tests
- pytest: 2 new (test_set_seen_carries_price, test_liked_drops_price_
even_if_supplied) + 1 updated to assert the new 5-arg repo
signature. 24 passed.
- vitest: 6 new for useDecisions (markSeen liked/disliked skip, price
snapshot, re-mark, null price, seenCount) + 5 new for decisionService
payload shape. 221 total passed, tsc clean.

- Increase Redis cache TTL from 30 minutes to 24 hours
- Add stale-while-revalidate: serve stale cache (>4h) immediately while
repopulating in background with SETNX lock to prevent concurrent rebuilds
- Add in-memory frontend LRU cache (5 entries) so repeat filter visits
are instant without network requests
- Invalidate frontend cache on listing refresh and task completion
- Add unit tests for get_cache_age, is_cache_stale, acquire_repopulation_lock
Collect browser-side worker round-trips, computation times, main-thread
operations, and feature counts, batch them client-side, and expose as
Prometheus histograms via a new POST /api/perf endpoint.
Listing stream fires immediately on auth without waiting for POI
fetch. POI distances are not needed for initial rendering and are
only computed when user selects POI metric or sets travel filters.
This saves ~200-500ms on initial load and keeps the stream on the
cached Redis path.
New GET /api/poi/distances/bulk returns all POI distances keyed by
listing ID, allowing the frontend to fetch distances separately
from the listing stream and keep the stream on the cached path.
Add last_updated timestamp to /api/status endpoint by querying
MAX(last_seen) across both listing tables. Display it in the
HealthIndicator as relative time (e.g. "2h ago") with full
date/time in the tooltip on hover.
When a session token expires, API calls return 401 but nothing caught
it — errors were shown as generic dialogs or swallowed. Now both
apiClient and streamingService detect 401 responses and clear auth
state, which causes App.tsx to render the login modal automatically.
Three-pronged fix for duplicate listings appearing in the UI:
1. Backend: Replace direct rpush cache writes with staged population
(write to temp key, then atomic RENAME to live key). Skip cache
writes entirely for POI-enriched requests. Clean staging keys on
invalidation.
2. Frontend: Add AbortController to cancel in-flight streaming requests
when loadListings is called again, preventing data mixing.
3. Frontend: Deduplicate features by URL during stream accumulation as
a safety net against any remaining server-side duplicates.
POIManager component in FilterPanel for creating/deleting POIs and
triggering distance calculations. PropertyCard shows travel time badges
(walk/cycle/transit) per POI. Map renders POI locations as red markers.
API client extended with POST body support for POI endpoints.
The crawler subdirectory was the only active project. Moving it to the
repo root simplifies paths and removes the unnecessary nesting. The
vqa/ and immoweb/ directories were legacy/unused and have been removed.
Updated .drone.yml, .gitignore, .claude/ docs, and skills to reflect
the new flat structure.
