REOPENED — normalize.py was never created; only rate-regime discount existed.
New backend/app/services/forecasting/normalize.py with normalize_demand(series):
multiplicative month-of-year deseasonalization of the raw monthly demand
SalesSeries (§9.4). Pure/deterministic; min-data guard (<2 full years / empty
month / overall_mean<=0 → factor 1.0, no divide-by-zero, no thin-data noise).
Exposes seasonal factors for explainability. Synthetic unit test: seasonality
removed (month means equalised), flat unchanged, thin/empty/all-zero safe.
DoD (module + doc + test) MET. Production wiring into
rate_sensitivity._align_sales_deltas DEFERRED (documented TODO): deseasonalizing
the short rate-driven series perturbs the recovered β/lag on current data —
needs a points-per-month gate / joint seasonal+rate estimation + backtest before
wiring. Forecast stack is advisory regardless. Refs #979
REOPENED#980: when effective competing supply is exhausted under positive demand
(projected_supply<=0, demand>0), deficit_index now caps to +1.0 (peak of [-1,+1])
instead of None. balance_ratio stays None (demand/0 undefined), but the strongest
build signal no longer reads downstream as thin data (market_fit fell to 0.5,
what_to_build dropped the cell). No-signal (supply<=0 AND demand<=0) stays None.
REOPENED#981: MAI now uses CBR key rate (macro_indicator key_rate/rf via
get_monthly_macro) as the market borrowing-cost proxy (~16-21%) instead of the
subsidized weighted rate (~7.83%), per §7.9 DoD. rate_kind='key_rate_proxy'.
If key_rate absent → rate_kind='market_unavailable' (no silent subsidy fallback).
Income (#946) still missing → payment_to_income None, confidence low.
778 forecasting tests green. Refs #980#981
REOPENED. PDF + Excel exporters read non-existent dict keys, so demand/supply/
scenario columns silently rendered "—". Tests passed only because the fixtures
were stale (hand-typed the same wrong keys → fixture agreed with buggy exporter).
- future_market: demand/supply → projected_demand_units/projected_supply_units
- scenarios: drop non-existent per-scenario "overall"; show primary-horizon
deficit_index from ScenarioForecast.forecasts (scoring.overall was NOT broken)
- Excel #991: add missing future_supply (index + breakdown) + confidence.factors
sections; add future_supply to PDF for parity
- tests: rebuild forecast/scenario fixtures from real DemandSupplyForecast /
ScenarioForecast as_dict(); contract-key regression guards fail on key-drift
(verified: reintroducing old keys fails the new tests). 28 passed.

REOPENED. _SALES_WINDOW_SQL derived "sales in window" from objective_lots_history
snapshots, but history is only ~17 days deep — every currently-sold lot had a
sold-snapshot in the window, so window-sales collapsed into the entire cumulative
sold stock (Автовокзал 6mo: 33,245 vs real ~2,308). Inflated absorption_rate
(~235%/mo with confidence=high), months_of_supply, unit_velocity, liquidity,
demand_concentration → contaminated forecast #950/#952.
Count window sales directly from objective_lots by contract_date in the window
(the real sale date — present on 100% of sold lots: 41,091/41,091). Return
contract of _query_sales_window unchanged (units/area/by-room ROLLUP); downstream
formulas untouched. Removed the now-dead objective_lots_history JOIN/CTE.
Regression test: lots sold outside window (contract_date out of range) not counted
(41,091 cumulative vs 2,308 window → absorption 2.35→0.04). 288 tests green.
Verification = prod compute_market_metrics(Автовокзал) post-deploy. Refs #949
REOPENED. L3 future-supply rows are computed per (district_name, dev_group_name)
but dev_group_name was never a key column — only embedded in method text. With
complex_id/obj_class NULL for L3, every dev_group of a district collapsed to one
upsert key → ~95.6% loss. Ground-truth (Академический, prod): should be 13,808
units / 15 dev_groups / 54 objects; only 1 row / 607 units survived.
Migration 128: ADD COLUMN supply_layers.dev_group_name TEXT + rebuild
uq_supply_layers_logical to (layer, district_name, complex_id, obj_class,
dev_group_name, source, snapshot_date) NULLS NOT DISTINCT (L1/L2 dev_group_name
NULL stays transparent → their dedup unchanged; L3 distinct groups no longer
collapse). Dry-run-verified vs prod catalog (applies clean, ROLLBACK clean).
Worker: SupplyLayerRow gains dev_group_name (L1/L2=None, L3=group); _UPSERT_SQL
adds it to INSERT/VALUES (CAST(:dev_group_name AS text)) + ON CONFLICT (key col,
not in DO UPDATE SET). Service+worker regression tests assert same-district/
different-dev_group → distinct keys (no collapse). 234 supply tests pass.
Deploy applies migration before container restart; collapsed data self-heals on
next supply_layers_refresh. Verification = prod re-measure post-deploy.

Complements the NULL-geom 500 fix. cad_exists_in_db (docstring: "is there
GEOMETRY") checked only row existence, not geom IS NOT NULL — so for the ~964
meta-but-NULL-geom parcels it returned True. Consequence after the 500 fix:
such a parcel fell into the analyze fallback, find_or_enqueue_fetch step 2 saw
cad_exists_in_db=True → returned ("ready", None) → NO NSPD fetch enqueued →
analyze looped to a 202 with job_id=null and the parcel was stuck "fetching"
forever (never pulled real geometry, never resolved).
Fix: add `AND geom IS NOT NULL` to all three EXISTS branches (aligns the
function with its docstring). Now a NULL-geom parcel → cad_exists_in_db=False →
a real NSPD fetch is enqueued (202 + real job_id) → geometry populates →
re-poll → analyze succeeds (or 404 not_in_nspd if NSPD lacks it). No more
stuck-202. Valid-geom parcels unaffected. All 3 callers want geometry-presence
semantics. 37 analyze/fetch/by-bbox tests green. Refs #944.
LIVE BUG (from #994, already merged): the analysis_runs persist call-site in
analyze_parcel extracted district via result_payload["district"]["district_name"]
— but a district dict without that key (real data: partial district lookup)
raised KeyError OUTSIDE the best-effort SAVEPOINT (extraction is at the call
site, not inside persist_analysis_run) → 500 on the LIVE /analyze endpoint.
Fix: .get("district_name") → None instead of raising. Caught by reviving the
analyze test suite (below).
Test-infra (the suite was un-runnable, which is why the bug shipped):
- Lazy-import WeasyPrint in layout_tz_pdf.py + trade_in_pdf.py (matches the
existing report_pdf.py / snapshot_pdf.py pattern). The eager top-level imports
made `app.main` (→ parcels/trade_in routers) un-importable on hosts without
WeasyPrint native libs (e.g. macOS dev), breaking pytest COLLECTION of the
whole api/v1 suite. WeasyPrint is still imported when a PDF is actually rendered.
- tests/conftest.py: autouse fixture clears app.dependency_overrides after each
test (anti-leak — a leaked get_db override caused real-DB connection attempts).
- test_parcel_by_bbox.py: rewrite get_db mocking from patch("...get_db") (a no-op
— FastAPI Depends holds the original ref) to app.dependency_overrides[get_db],
add explicit X-Authenticated-User header (RBAC gate), patch latest_run_dates,
+ a new test asserting last_analysis_date from a latest run (#994). 5/5 green.
NOTE: reviving collectability exposes PRE-EXISTING rot in other api/v1 suites
(analyze/admin/best_layouts: RBAC-header + stale-assertion/mock drift) — those
are NOT regressions from this PR (they were uncollectable before) and are
tracked separately for a deliberate suite-rehab + CI test-gate effort.
Refs #994.
Persist each successful POST /analyze into analysis_runs (migration 127):
best-effort SAVEPOINT-wrapped INSERT in a thin analysis_runs repository, then
explicit db.commit() (get_db has no commit-on-success; SAVEPOINT RELEASE alone
does not persist — without the commit the row rolls back on request teardown,
a silent no-op caught in code review). A persist failure never breaks the
response or poisons the session. Result serialized via jsonable_encoder→
json.dumps (handles embedded Pydantic models/dates); confidence/status
normalized to satisfy the 127 CHECK constraints (unknown→NULL/'complete').
Populate by-bbox last_analysis_date from v_analysis_runs_latest via a single
batch query (no N+1), replacing the #307 placeholder. The read is best-effort
wrapped too — a view-missing deploy window or future drift must not 500 the
map (falls back to last_analysis_date=None).
Additive only — analyze response shape unchanged. Tests: by-bbox suite patches
latest_run_dates (mock-db returns same rows for any query) + new test asserts
ISO last_analysis_date from a latest run. Analyze mock-suite unaffected
(graceful side_effect overflow + best-effort persist absorb the extra INSERT).
Incidental: ruff-format fixed one pre-existing f-string spacing (line ~2391)
the format hook flags on touch.
Closes#994. Refs #961.
PR #335 использовал `with db.begin_nested():` SAVEPOINT для per-row UPDATE,
но outer transaction никогда не commit'ился. После цикла Celery task
закрывал session (`db.close()` в finally) → autobegin'd outer tx
rollback → все UPDATE'ы теряются.
Симптом: task завершается с processed=3 succeeded=3, в Glitchtip нет ошибок,
но в БД ни одного catalog_scraped_at != NULL.
Fix: добавлен db.commit() после цикла + rollback на ошибку commit'а.
PR #322 used placeholder URLs:
- /api/object/{id}/documents -> 404 (Playwright showed: 5 real endpoints:
document/rpd / developer/report / project/documentation /
documentation/other / document/permits). Replaced with 5 parallel
fetches + merge into single upsert_documents call.
- /api/object/{id}/checks -> 404. 6 checkboxes likely inline in bulk
kn/object payload; endpoint /checks does not exist. Commented out
_fetch_obj_checks_safe with TODO for separate investigation PR.
- BrowserSession Semaphore(3) -> Semaphore(6) — double concurrency
for intra-object gather.
GlitchTip: kn_scrape_failures run #19 showed 40 failures each for
both placeholder endpoints across first 30 objects of 1532.
