Subject: [PATCH 18/73] feat(29-07): standalone econ per-release cache island
(keep-all-vintages, path-traversal defense)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
- Add packages/econ/src/mostlyright/econ/_cache.py mirroring the CWOP
_cache.py standalone-island discipline: filelock-guarded read-modify-write
parquet cache at ~/.mostlyright/cache/v1/econ/{indicator}/{year}/{month}.parquet
with atomic .tmp + os.replace writes.
- Imports NONE of the parity-coupled weather persistence layer (grep-asserted);
reuses only the shared _internal._bounds.assert_path_under +
_internal._cache_dir.resolve_cache_root_without_v1.
- Own _ECON_KEY_RE validator (lowercase-snake, forbids / \ . ..) +
assert_path_under backstop for path-traversal defense (T-29-19).
- Explicit pyarrow schema from EconObservationsSchema.COLUMNS (bool added to
the dtype map for settlement_grade) so heterogeneous rows preserve all
columns (no first-row inference drop).
- Keep-all-vintages dedup: first-seen-wins on the VINTAGE key
(indicator, period, vintage_date, source) — NOT (indicator, period) — so
the first-print row is never collapsed by a later vintage (T-29-21).
- NO current-month / revision-window write-skip: the per-indicator revision
window governs settlement_grade at read time, not whether to write.
- write/read/read_window/invalidate + econ_cache_path; honors
MOSTLYRIGHT_CACHE_DIR; RMW under one FileLock (lost-update defense, T-29-20).
- TDD: 25 tests in packages/econ/tests/test_cache.py (roundtrip+idempotence,
keep-all-vintages, true-dup dedup, path traversal, cache-dir env,
heterogeneous columns, sequential-merge accumulation, window span, firewall
grep gate).

+"""Econ per-release persistence — monthly parquet cache for backtest replay.
+
+Path layout::
+
+ ~/.mostlyright/cache/v1/econ///.parquet
+
+Honors ``MOSTLYRIGHT_CACHE_DIR`` (the shared SDK cache root) so relocating the
+cache moves the econ partitions with everything else.
+
+**Deliberately a standalone island** (the CWOP ``_cache.py`` discipline at
+package granularity). This module imports NONE of the parity-coupled weather
+persistence layer — that layer pulls ``OBSERVATION_SCHEMA`` + the LST tz map
+and applies a *current-LST-month-skip* designed for re-fetchable AWC/IEM/GHCNh
+weather data. Re-using its atomic-write helper would couple econ persistence to
+the parity firewall's invalidation semantics; the ~20-line atomic writer here
+is duplicated on purpose so econ stays on its own island (see CLAUDE.md "Data +
+parity rules" and the CWOP adapter precedent). Econ is also NEVER registered in
+the four weather parity files (``research()``, ``merge/observations.py``,
+``merge/climate.py``, ``live/_sources.py``).
+
+**The load-bearing difference from BOTH weather and CWOP:**
+
+- Weather collapses to a single row per ``(station, date)`` via a
+ ``report_type_priority`` dedup. Econ does the OPPOSITE — it KEEPS every
+ vintage. The dedup key is the VINTAGE key ``(indicator, period,
+ vintage_date, source)``, NOT ``(indicator, period)``, so two rows sharing an
+ observation period but carrying different ``vintage_date`` values BOTH
+ persist. Read-time filtering on ``settlement_grade`` (``econ.history`` with
+ ``vintages="settlement"|"all"``) selects a vintage — never a merge collapse.
+ Collapsing vintages would destroy the first-print settlement store that a
+ Kalshi NHIGH/NLOW-style econ backtest depends on.
+- CWOP has NO current-month skip because its APRS-IS stream is ephemeral
+ (persisting the current month is the only chance to retain it). Econ has NO
+ write-skip *either*, but for a different reason: econ CAN re-fetch, and it
+ keeps all vintages, so the per-indicator revision window (CPI ~45d, GDP ~60d
+ advance→second→third) governs which vintage is ``settlement_grade=True`` AT
+ READ TIME — it does not govern whether to write. There is therefore no
+ current-month / revision-window write-skip in this module.
+
+Concurrency: a write is a read-modify-write *merge* into an existing monthly
+partition, serialized under a single per-path ``FileLock`` so two writers
+targeting the same ``(indicator, year, month)`` cannot lost-update each other —
+the second writer reads the first's already-committed rows and dedups on top.
+
+Source identity: persisted rows are stamped ``source="econ.cache"`` (distinct
+from the live agency tags ``alfred`` / ``bls.v1`` / ``bea`` / …) so a consumer
+reading them back via the econ history surface knows the provenance is a
+cache-read, not a fresh agency pull. Econ data still never enters the
+parity-frozen weather merge/research path.

- kalshi_econ.resolve(series_ticker) -> frozen EconResolution(agency,
indicator, settlement_grade, contract_terms_url), mirroring kalshi_nhigh's
deterministic resolve() (up-front TypeError guard; ValueError on unknown
ticker naming the known roots; never returns None)
- routes PER-SERIES off the codegen'd SETTLEMENT_ROUTING agency NAMES, never
a settlement-source URL (Pitfall 2 / STRIDE T-29-09 SSRF); grep-gate 0
- proven per-series split: KXUSPPI (MoM) -> TradingEconomics/False vs
KXUSPPIYOY (YoY) -> BLS/True; longest-prefix root match so dated tickers
(KXCPIYOY-26JUL) and KXUSPPIYOY do not collapse onto the shorter KXUSPPI rule
- uses rule.agency directly (already canonical) with an AGENCY_NAMES
membership assert — NOT normalize_agency_name, which raises on the
already-canonical FederalReserve/TradingEconomics short forms
- ECON-17: EconResolution has no value field, so a TE-settled series can only
be labeled settlement_grade=False, never assigned a fabricated TE number
- catalog/__init__.py exports kalshi_econ alongside kalshi_nhigh/kalshi_nlow
- markets pyproject depends on mostlyrightmd-econ>=1.11.0,<2.0 (one-way
markets -> econ; uv.lock reconciled via uv sync)
- 13 contract tests; parity firewall untouched (no econ in the 4 weather files)

+"""Kalshi Economics contract resolver (per-series agency-NAME routing).
+
+Kalshi Economics markets (CPI, PPI, NFP, GDP, jobless claims, Fed decision, …)
+each settle against a specific agency's first print. ``resolve(series_ticker)``
+is the deterministic mapping from a Kalshi Economics series/contract ticker to
+an :class:`EconResolution` ``(agency, indicator, settlement_grade,
+contract_terms_url)`` tuple that downstream code (``research_econ()``, plan
+29-08) uses to join the correct agency first-print row.
+
+It mirrors :mod:`mostlyright.markets.catalog.kalshi_nhigh` — a frozen-dataclass
+result plus a deterministic ``resolve()`` with an up-front type guard, a
+``ValueError`` on unknown tickers (it NEVER returns ``None``), and a
+``__all__`` of ``[ResultClass, "resolve"]``.
+
+Routing is genuinely PER-SERIES, driven by the curated
+:data:`~mostlyright.econ._settlement_map.SETTLEMENT_ROUTING` table — keyed on
+canonical Kalshi series ROOT tickers and the agency NAMES those roots settle to.
+The load-bearing case is the PPI family split: ``KXUSPPI`` (PPI MoM) settles to
+Trading Economics at ``settlement_grade=False`` while its sibling
+``KXUSPPIYOY`` (PPI YoY) settles to BLS at ``settlement_grade=True``. Assuming
+"the government first print" for the 48 Trading-Economics-settled series
+(``KXUSPPI``, ``KXUSNFP``, and international variants) would mis-settle every one
+of them.
+
+SSRF / sloppy-URL firewall (Pitfall 2; STRIDE T-29-09): this resolver reads
+ONLY the pre-curated agency NAMES in ``SETTLEMENT_ROUTING``. It NEVER fetches or
+parses the Kalshi-supplied settlement-source URL field handed to us by series
+metadata — those URLs are demonstrably wrong live (``KXPAYROLLS`` carries
+``name="BLS"`` but a URL pointing at ``ppi.nr0.htm``; one series' URL points at
+"San Francisco Unified School District"). Routing on the URL would settle NFP
+contracts against PPI data. So: NAME only, from the curated table. (The literal
+Kalshi field name is deliberately kept out of this module so the CI grep gate
+that asserts "no URL routing" stays green.)
+
+ECON-17: for a Trading-Economics-settled series the resolver only labels
+``settlement_grade=False``. It structurally cannot emit a fabricated Trading
+Economics number — :class:`EconResolution` carries no value field; the value
+stays the agency first-print in the data layer.

- Add _history.py: history(indicator, from_date, to_date, *, vintages='settlement'|'all')
* FEDS floor checked first; cache read then fetch-then-persist on miss; re-read
* read-time vintage filter (settlement=first-print only, all=every vintage);
settlement is always a subset of all (clean-partition property)
* not-yet-released raises IndicatorNotYetReleasedError (never []/None)
* EXHAUSTIVE indicator->fetcher dispatch over all 6 families incl.
ppi/ppi_yoy->bls (BLOCKER-1) and jobless_claims->dol (BLOCKER-3)
* lazy pandas import with install hint ([pandas] extra)
- Add _releases.py: releases(indicator) -> curated ReleaseEvent schedule
(BLS empsit/CPI, BEA GDP, FOMC calendar, DOL weekly per ECON-13)
- _floor.py: add jobless_claims / cpi_core / cpi_core_yoy floors — the dispatch
is exhaustive and the floor is checked first, so a routed indicator MUST have a
floor or the guard structurally rejects a released-window request (the exact
reason jobless_claims could not emit settlement rows)
- __init__.py: wire history/releases from new modules (research_econ stub stays
for Task 2); keep exact public signatures + __all__
- Tests: partition invariant (incl. hypothesis property), FEDS floor, cache
miss->hit, not-yet-released, PPI dispatch (Test 7), jobless settlement non-empty
+ future-week raise (Test 8/8b)

+"""``econ.history`` — read-time vintage filter, FEDS-floor-enforced, fetch-on-miss.
+
+``history(indicator, from_date, to_date, *, vintages="settlement"|"all")`` is the
+econ vertical's core read surface (plan 29-08, replacing the 29-01 stub). It
+composes everything upstream:
+
+1. **FEDS floor first** — :func:`~mostlyright.econ._floor.assert_within_floor`
+ raises the out-of-range error when ``from_date`` predates the indicator's
+ FEDS-2026-010 first Kalshi contract (a below-floor backtest asks for outcomes
+ the venue never priced).
+2. **Cache read** — :func:`~mostlyright.econ._cache.read_econ_window` returns the
+ persisted vintages for the window. On a MISS the indicator is dispatched to
+ its agency fetcher (:data:`INDICATOR_FETCHERS`), the rows are persisted via
+ :func:`~mostlyright.econ._cache.write_econ_cache`, and the window is re-read
+ (so the SECOND call for the same window reads from cache with no fetch).
+3. **Read-time vintage filter** — ``"settlement"`` keeps only the settlement-grade
+ first print (``settlement_grade is True``), ``"all"`` keeps every vintage. This
+ is the load-bearing econ difference from weather: the store keeps ALL vintages
+ and the caller selects one at READ time (never a merge collapse).
+4. **Not-yet-released is an error, never empty** — when the window yields no
+ relevant rows, :class:`~mostlyright.core.exceptions.IndicatorNotYetReleasedError`
+ is raised (with the release calendar's expected datetime when known). ``history``
+ NEVER returns ``[]``/``None`` for a missing release.
+
+**The dispatch table is EXHAUSTIVE over the 6 CONTEXT Area-1 families** — every
+indicator in the ``schema.econ.observations.v1`` vocabulary has a code path; an
+indicator with no entry raises a clear ``ValueError`` (never a silent empty
+frame). The load-bearing entries the checker flagged:
+
+- ``ppi`` / ``ppi_yoy`` → ``bls`` (BLOCKER-1: PPI final-demand ``WPSFD4`` is now
+ fetchable through the public surface).
+- ``jobless_claims`` → ``dol`` (BLOCKER-3: the keyed ALFRED-ICSA first-release
+ path emits ``settlement_grade=True``, so a released jobless-claims window
+ returns non-empty settlement rows; only a genuinely future/unreleased week
+ raises ``IndicatorNotYetReleasedError``). ``jobless_claims`` is NEVER
+ special-cased to always-empty / always-False — that is the exact bug the
+ checker flagged.

+pandas is the ``[pandas]`` extra (``history`` returns a DataFrame): it is

* resolve contract via econ-side resolve_settlement (NO markets import — the
workspace edge stays one-way markets->econ; econ depends only on core)

* build pairs with knowledge_time=vintage_date + resolved outcome metadata

* leakage guard: assert_no_leakage(pairs, as_of) rejects any vintage_date
after the as_of cutoff — a future revision can never leak (T-29-23)
* TE-settled series (KXUSPPI, KXUSNFP): serve AGENCY first print labeled
settlement_grade=False + emit DivergenceWarning; NEVER fabricate a TE value
(ECON-17 / T-29-24)
- _settlement_map.py: add resolve_settlement(ticker) -> (root, SettlementRule),
the econ-side exact-then-longest-root resolver (same SETTLEMENT_ROUTING table
the markets kalshi_econ.resolve reads) so research_econ resolves without a
forbidden econ->markets import
- __init__.py: wire research_econ from _research (replaces the Task 2 stub)
- Tests: pairs shape + knowledge_time; leakage guard (reject future vintage,
pass past vintage, hypothesis property over as_of/vintage offset); TE
divergence warning + settlement_grade=False + agency value (not fabricated);
unknown contract raises; structural no-markets-import assertion

+"""``econ.research_econ`` — leakage-free settlement pairs (the vertical's payoff).
+
+``research_econ(series_or_contract, from_date, to_date, *, as_of=None)`` (plan
+29-08, replacing the 29-01 stub) joins a prediction-market contract to the
+settlement-grade FIRST-PRINT vintage of the agency indicator it settles against,
+and returns training pairs that "backtest the same way they trade":
+
+1. **Resolve** the contract to its settlement mapping — ``(agency, indicator,
+ settlement_grade)`` — via the econ-side routing table
+ (:func:`~mostlyright.econ._settlement_map.resolve_settlement`). This reads the
+ SAME ``SETTLEMENT_ROUTING`` table the markets ``kalshi_econ.resolve`` reads, so
+ the two resolvers agree by construction — but it does NOT import the markets
+ package. The workspace edge is strictly one-way ``markets → econ`` (29-04 added
+ ``mostlyrightmd-econ`` to the markets deps); adding the reverse would cycle
+ ``uv sync`` / ``uv build`` (T-29-27). ``econ`` depends only on ``core``.
+2. **Pull the first print** via ``history(indicator, from_date, to_date,
+ vintages="settlement")`` — the settlement-grade vintage (the value as-of the
+ Kalshi expiration, first-print discipline).
+3. **Build the pairs frame** with ``knowledge_time = vintage_date`` (the leakage
+ cutoff column) and the resolved market-outcome metadata (``agency``,
+ contract-level ``settlement_grade``).
+4. **Leakage guard** — when ``as_of`` (a :class:`~mostlyright.core.TimePoint`) is
+ given, :func:`~mostlyright.core.temporal.leakage.assert_no_leakage` rejects any
+ row whose ``knowledge_time > as_of``, so a FUTURE revision can never leak into
+ a backtest (ECON-14 / T-29-23; property-tested).
+5. **TE divergence, honestly labeled** — for a Trading-Economics-settled series
+ (the 48 TE contracts: KXUSPPI PPI-MoM, KXUSNFP, …) the join uses the AGENCY
+ first print as the value but labels the pair ``settlement_grade=False`` and
+ emits a :class:`DivergenceWarning` naming the series and that Trading Economics
+ is the (unlicensed) settlement authority. It NEVER fabricates or approximates a
+ TE value (ECON-17 / T-29-24).
+
+The live Kalshi/Polymarket outcome-price join (attaching the traded YES/NO price
+panel to each settlement period) is a live-network concern exercised in the 29-10
+smoke; this module establishes the leakage-safe settlement-pair SEMANTICS (the
+resolved outcome metadata + first-print value + ``knowledge_time`` + the
+``assert_no_leakage`` gate) that the price join layers onto. pandas is the
+``[pandas]`` extra — lazy-imported with an install hint.

Subject: [PATCH 22/73] feat(29-08): Polymarket econ derive (in-package httpx)
+ Kalshi venue price-history
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
- Add econ/_polymarket.py: derive(slug, ...) — SECONDARY-venue econ outcome derive
* keyless gamma /events (question/outcomes/resolutionSource/umaResolutionStatus)
+ CLOB /prices-history price panel, via a THIN IN-PACKAGE httpx GET
* does NOT import the markets package and adds NO mostlyrightmd-markets dep —
the workspace edge stays one-way markets->econ (no cycle; T-29-27). The literal
forbidden token is kept out of the file entirely (prose + code)
* reuses core _internal._http timeout; HTTPS + User-Agent; non-JSON body raises
- Add markets/econ_trades.py: candles(ticker, ...) — Kalshi OHLC for settled econ
markets, mirroring kalshi_trades
* documented shallow-depth limit (MAX_PUBLIC_DEPTH_NOTE + docstring): public API
surfaces only ~50-90 recent settled markets (oldest ~2026-05); a pre-2026-05
window returns labeled-empty (public_depth_limited=True), never a fabricated
2021-2023 candle (ECON-20 / Pitfall 3)
* FEDS floor enforced as a data-availability contract (below-floor -> raise);
resolves the econ indicator from the ticker via econ._settlement_map
- Tests: gamma/CLOB derive shape + no-markets-import/no-markets-dep guards
(econ tests); OHLC shape, pre-depth labeled-empty, documented note, below-floor
raise (markets tests)

+"""Polymarket econ derive — the SECONDARY venue (gamma ``/events`` + CLOB history).
+
+Kalshi is econ v1's PRIMARY settlement venue (the resolver-driven join in
+``research_econ``). Polymarket is the SECONDARY venue: this module derives the
+Fed/CPI/PCE econ market outcomes from Polymarket's keyless gamma ``/events``
+endpoint (the market question / outcomes / resolution source) and attaches the
+CLOB ``/prices-history`` price panel, producing a secondary-venue outcome shape
+``research_econ`` can join alongside the Kalshi outcome.
+
+**In-package httpx, no cross-package import (checker BLOCKER 2 / T-29-27).** The
+workspace dependency edge is strictly ONE-WAY ``markets → econ``: plan 29-04
+(Wave 3) added ``mostlyrightmd-econ`` to the **markets** ``[project].dependencies``
+(the markets resolver imports econ's ``_settlement_map``). ``econ`` therefore MUST
+NOT depend on the markets package — adding that edge would create a cycle that
+breaks ``uv sync`` / ``uv build``. So this module reimplements the thin keyless
+gamma/CLOB GET in-package using ``httpx`` (reusing the core
+``mostlyright._internal._http`` retry discipline) rather than importing the
+existing markets Polymarket client. ``econ`` depends only on ``core``.
+
+Verified live shapes (RESEARCH ECON-18, keyless, HTTP 200):
+
+- gamma ``GET /events?slug=`` → an event object carrying ``markets[]``,
+ each ``{question, conditionId, clobTokenIds, outcomes, outcomePrices,
+ umaResolutionStatus, resolutionSource, description}``. (The Fed event
+ ``fed-decision-in-july-181`` carried $45.7M volume, 5 markets.)
+- CLOB ``GET /prices-history?interval=max&market=&fidelity=60`` →
+ ``{history:[{t:, p:}...]}`` (~720 points keyless).
+
+Security: no key is required (both endpoints are public). HTTPS is enforced; a
+Cloudfront 403 on a blank User-Agent is avoided by always sending one. A hostile
+/ non-JSON body raises rather than being parsed as an empty outcome.

+"""Kalshi venue price-history for SETTLED econ markets — with documented depth.
+
+``candles(...)`` retrieves Kalshi OHLC candlesticks for a settled economics market
+(``/series/{s}/markets/{m}/candlesticks``), mirroring
+:mod:`mostlyright.markets.kalshi_trades`. It is the venue-history companion to the
+econ vertical's settlement join (``mostlyright.econ.research_econ``): where
+``research_econ`` produces the leakage-safe settlement PAIRS, this surfaces the
+traded price panel for a settled econ contract.
+
+**The shallow-depth limit is a first-class, documented behavior (RESEARCH Pitfall
+3 / ECON-20).** The PUBLIC Kalshi API surfaces only ~50-90 RECENT settled markets
+per series (oldest ~2026-05), and a market's candlesticks span its own ~1-month
+life. The FEDS-2026-010 first-contract dates (2021-2023) are therefore NOT
+retrievable from the public settled-markets endpoint — a deep backtest needs the
+FEDS replication dataset or a running collector. This module refuses to pretend
+otherwise:
+
+- A window entirely before the public-depth floor (~2026-05) returns an
+ EMPTY DataFrame stamped ``df.attrs["public_depth_limited"] = True`` — never a
+ fabricated 2021-2023 candle.
+- A window below the indicator's FEDS floor raises
+ :class:`~mostlyright.core.exceptions.DataAvailabilityError` (the floor is a
+ data-availability CONTRACT, mirroring ``econ.history``).
+
+The realistic depth expectation is documented in the module docstring and the
+:data:`MAX_PUBLIC_DEPTH_NOTE` constant.
+
+This module lives in ``mostlyright.markets`` (not econ) because it drives the
+Kalshi venue client — the workspace edge is one-way ``markets → econ``, so it MAY
+reuse both the markets Kalshi client and the econ floor/routing tables.

Subject: [PATCH 23/73] feat(29-09): scaffold @mostlyrightmd/econ + codegen
econ schema/settlement, mirror IndicatorNotYetReleasedError
- Add schema.econ.observations.v1.json to codegen SCHEMA_FILES -> generated
EconObservationsV1 type + ajv validator (codegen-derived, not hand-written)
- Add emitKalshiEconSettlement: codegen the per-series routing table + agency
vocabulary from kalshi-econ-settlement.json into packages-ts/econ/src/generated/
(Python<->TS anti-drift contract; deterministic --check)
- Add IndicatorNotYetReleasedError to packages-ts/core/src/exceptions/index.ts,
errorCode INDICATOR_NOT_YET_RELEASED, mirroring the Python class
- Scaffold packages-ts/econ (package.json @mostlyrightmd/econ v1.11.0 lockstep,
tsconfig/tsup/vitest/README/.gitignore); src/schema.ts re-exports the generated
type; src/index.ts re-exports schema + error + settlement table

+# @mostlyrightmd/econ
+
+Economic-indicator data for the [mostlyright](https://github.com/mostlyrightmd/mostlyright-sdk) TypeScript SDK — CPI (headline / core / YoY), PPI, nonfarm payrolls (NFP), U3 unemployment, initial jobless claims, GDP, and Fed decisions, sourced from FRED/ALFRED + BLS/BEA/DOL/Federal Reserve and joined to Kalshi + Polymarket econ markets for **leakage-free settlement pairs**. Mirrors the Python `mostlyrightmd-econ` distribution surface. Declares `@mostlyrightmd/core` as a peer dependency.
+
+## Install
+
+```bash
+pnpm add @mostlyrightmd/econ @mostlyrightmd/core
+```
+
+## Surface
+
+Surface-equivalent to the Python `mostlyright.econ` vertical (camelCase TS signatures):
+
+- `history(indicator, fromDate, toDate, { vintages })` — observation rows. `vintages: "settlement"` (default) returns the settlement-grade first print (the value as-of the Kalshi expiration); `vintages: "all"` returns every vintage for feature engineering.
+- `releases(indicator)` — the release calendar / schedule for an indicator.
+- `researchEcon(seriesOrContract, fromDate, toDate, { asOf })` — leakage-free settlement pairs (market outcome + first-print value + as-of features). When `asOf` is given, any pair whose `knowledge_time` (= `vintage_date`) is after it throws `LeakageError` — a future revision can never leak into a backtest.
+
+## Load-bearing invariants (parity with Python)
+
+- **First-print / ALFRED vintage discipline.** Kalshi settlements contractually exclude post-expiration revisions; the backtest layer serves as-released vintages, never the revised series. Vintage selection happens at read time via `vintages`.
+- **Per-series settlement routing.** 48 of the Kalshi Economics series settle to **Trading Economics**, not the government agency (incl. `KXUSPPI` PPI-MoM, `KXUSNFP`). Routing is genuinely per-series: `KXUSPPI` (MoM) → TradingEconomics, but `KXUSPPIYOY` (YoY) → BLS. The routing table is codegen-shared from `schemas/kalshi-econ-settlement.json` (the Python↔TS anti-drift gate).
+- **TE-settled series are honest, never fabricated.** For a Trading-Economics-settled series, `researchEcon` ships the agency first print labeled `settlementGrade=false` and emits a divergence warning — it NEVER fabricates a TE value.
+- **`IndicatorNotYetReleasedError`, not `[]`/`null`.** "Not yet released" is a normal, branchable control state distinct from "unavailable". The error is re-exported from `@mostlyrightmd/core` (Python↔TS lockstep taxonomy).
+- **Parity firewall.** Econ never registers into the TS `research()` / merge / live-source equivalents — an econ row must never reach the weather settlement join (the same isolation the Python vertical and CWOP use).
+
+## Browser / Node constraints
+
+The fetch layer uses the standard `fetch` API and JSON — no Node-only API on a browser-viable path (mirrors the weather TS browser-safe boundary). API keys (`FRED_API_KEY` / `BLS_API_KEY` for ALFRED / BLS-v2) are read from the Node environment only; they are never bundled into a browser build.
+
+## Schema
+
+The `EconObservationRow` (`schema.econ.observations.v1`) column types are **codegen-derived** from the shared JSON via `@mostlyrightmd/codegen` — never hand-written in TS. Regenerate with `pnpm codegen`.

Subject: [PATCH 24/73] test(29-09): add failing econ surface parity tests
(RED)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Covers the 5 plan behaviors mirroring the Python econ vertical:
- researchEcon pairs with knowledge_time=vintage_date
- leakage guard (vintage_date > asOf throws LeakageError)
- TE divergence (KXUSPPI: agency first-print, settlementGrade=false + warning,
no fabricated TE value)
- not-yet-released throws IndicatorNotYetReleasedError (never []/null)
- resolver per-series split (KXUSPPIYOY->BLS/true, KXUSPPI->TE/false)
Fetch layer injected via { fetchRows } so no live network is touched. Fails to
load (impl files history.ts/researchEcon.ts/resolvers/kalshiEcon.ts absent) — RED.

Subject: [PATCH 25/73] feat(29-09): port history/releases/researchEcon +
kalshiEcon resolver to TS (GREEN)
Surface-equivalent to the Python econ vertical (object-array output, no DataFrame):
- resolvers/kalshiEcon.ts: kalshiEconResolve reads the codegen-shared
SETTLEMENT_ROUTING, exact-then-longest-prefix (KXUSPPIYOY->BLS/true beats the
shorter KXUSPPI->TE/false); throws EconTickerError on unknown ticker
- floor.ts: FEDS-2026-010 first-contract floor -> DataAvailabilityError out_of_window
- fetchers.ts: browser-safe fetch() clients (BLS latest-revised settlement_grade
false; ALFRED first-print settlement_grade true); keys read from Node env only
via a guarded readEnvKey, never bundled into a browser build
- history.ts: history (floor -> fetch -> vintage filter -> IndicatorNotYetReleased)
+ releases (curated schedule); fetchRows injection seam for tests
- researchEcon.ts: resolve -> settlement first-print -> knowledge_time=vintage_date
-> TE divergence (agency proxy, settlementGrade=false + warning, no fabricated
TE value) -> assertNoLeakage on the asOf cutoff
- index.ts wires the real bodies
All 22 vitest tests pass; typecheck + build green; TS parity firewall intact
(econ imports only @mostlyrightmd/core, never research/merge/live).

+"""Parity-firewall regression — econ is NEVER registered in the 4 weather files.
+
+The load-bearing isolation guarantee for the econ vertical (the econ analog of
+the CWOP firewall tests). ``mostlyright.econ`` carries its OWN
+``schema.econ.observations.v1`` + its OWN :data:`ECON_SOURCES` source-identity
+union + its OWN error taxonomy, and MUST stay strictly out of the four
+parity-frozen weather files:
+
+1. ``mostlyright._internal.merge.observations`` — the ``SOURCE_PRIORITY`` dedup map.
+2. ``mostlyright._internal.merge.climate`` — the climate ``REPORT_TYPE_PRIORITY`` policy.
+3. ``mostlyright.live._sources`` — the live source registry.
+4. ``mostlyright.research`` — the v0.14.1 settlement join.
+
+Any drift here invalidates the parity gate (an econ macro-release row leaking
+into the weather ``max/min(temp_f)`` merge would silently corrupt a Kalshi
+NHIGH/NLOW settlement). These assertions exist so that IF a future change ever
+registers econ into a parity file — a source tag in ``SOURCE_PRIORITY``, the
+schema in core's eager registry, an ``import mostlyright.econ`` in one of the four
+modules — this test FAILS. That is their entire purpose (STRIDE T-29-31).
+
+The workspace dependency edge is strictly one-way ``markets -> econ`` (29-04
+added ``mostlyrightmd-econ`` to the *markets* deps): ``econ`` depends only on
+``core``. This file also proves the reverse edge is absent — ``econ`` never
+imports ``mostlyright.markets`` (that would cycle ``uv sync`` / ``uv build``;
+T-29-27).
+
+Fast (in CI): every assertion is a static import / constant / source-grep — no

count), passes otherwise; boundary vintage_date == as_of is safe (strict >).
- Partition: hypothesis proves the production read-time filter

+# Economic-indicators vertical (`mostlyright.econ`)
+
+Macro-release data for prediction-market settlement research — CPI (headline /
+core / YoY), PPI, nonfarm payrolls (NFP) and revisions, U3 unemployment, initial
+jobless claims, GDP, and Fed funds decisions — sourced from FRED/ALFRED +
+BLS/BEA/DOL/Federal Reserve and joined to Kalshi and Polymarket econ markets for
+**leakage-free settlement pairs**.
+
+> **Econ is standalone — a firewall vertical.** It never feeds `research()`, the
+> weather merge layer (`_internal/merge/observations.py`'s `SOURCE_PRIORITY`,
+> `_internal/merge/climate.py`), or `live/_sources.py`. It carries its own
+> `schema.econ.observations.v1` (separate from the parity-frozen
+> `schema.observation.v1`), its own per-release cache namespace, and its own error
+> taxonomy. A macro release must **never** be routed through the weather
+> settlement join, and the weather merge layer must never see an econ row. This
+> isolation is the same discipline CWOP uses, and it is a **permanently-enforced,
+> tested invariant** — `packages/econ/tests/test_firewall.py` fails if econ is
+> ever registered in any of the four parity files. The workspace dependency edge
+> is strictly one-way `markets → econ`; `econ` depends only on `core`.
+
+## Install
+
+```bash
+pip install mostlyrightmd-econ[pandas] # history()/research_econ() return DataFrames
+```
+
+The raw fetchers and cache work without pandas; the read surfaces
+(`history`, `research_econ`) return a `pandas.DataFrame`, so install the
+`[pandas]` extra (or any extra that pulls pandas) to use them.
+
+## Public surface
+
+```python
+from mostlyright.econ import history, releases, research_econ
+```
+
+### `history(indicator, from_date, to_date, *, vintages="settlement")`
+
+Observation rows for an indicator across a date range, as a
+`schema.econ.observations.v1` DataFrame.
+
+```python
+# The settlement-grade FIRST PRINT (the value as-of the Kalshi expiration).
+df = history("cpi", "2026-05-01", "2026-06-30") # vintages="settlement" (default)
+
+# Every vintage kept — for feature engineering.
+allv = history("cpi", "2026-05-01", "2026-06-30", vintages="all")
+```
+
+- **The load-bearing econ difference from weather: vintage is first-class.**
+ Weather collapses to one row per `(station, date)` via a dedup. Econ does the
+ OPPOSITE — it KEEPS every vintage and filters at **read** time. `vintages="settlement"`
+ keeps only the settlement-grade first print (`settlement_grade == True`);
+ `vintages="all"` keeps every vintage. `settlement` is always a subset of `all`
+ (a clean partition — property-proven in `test_leakage_property.py`).
+- **Not-yet-released is an error, never an empty frame.** When a window has no
+ relevant rows (a scheduled release has not landed), `history` raises
+ `IndicatorNotYetReleasedError` — it NEVER returns `[]`/`None`.
+- **A below-floor window raises.** A `from_date` before the indicator's
+ FEDS-2026-010 first Kalshi contract raises `DataAvailabilityError`
+ (`reason="out_of_window"`) — a below-floor backtest asks for outcomes the venue
+ never priced.
+
+The indicator vocabulary: `cpi`, `cpi_core`, `cpi_yoy`, `nfp`, `u3`, `gdp`,
+`ppi`, `ppi_yoy`, `jobless_claims`, `fed_funds`. An unknown indicator raises a
+clear `ValueError` (the dispatch table is exhaustive — never a silent empty
+frame).
+
+### `releases(indicator)`
+
+The release calendar for an indicator — a list of `ReleaseEvent`
+(`indicator`, `period`, `release_datetime` in UTC, `agency`), sorted ascending.
+The companion signal to `IndicatorNotYetReleasedError`: `history` tells you a
+print has not landed; `releases` tells you when to come back.
+
+```python
+for ev in releases("nfp"):
+ print(ev.period, ev.release_datetime.isoformat(), ev.agency)
+```
+
+v1 ships a curated, offline-deterministic schedule table (no network, no key); a
+live agency-calendar fetch is a documented fast-follow. An unschedulable
+indicator raises `ValueError`.
+
+### `research_econ(series_or_contract, from_date, to_date, *, as_of=None)`
+
+Leakage-free settlement pairs — the vertical's payoff. Joins a prediction-market
+contract to the settlement-grade first-print vintage of the agency indicator it
+settles against, and returns training pairs that "backtest the same way they
+trade."
+
+```python
+from mostlyright.core import TimePoint
+
+pairs = research_econ("KXCPIYOY", "2026-05-01", "2026-06-30")
+
+# With a leakage cutoff: any pair whose vintage_date > as_of raises LeakageError.
+pairs = research_econ("KXCPIYOY", "2026-05-01", "2026-06-30",
+ as_of=TimePoint("2026-06-01T00:00:00Z"))
+```
+
+- Resolves the contract to `(agency, indicator, settlement_grade)` via the
+ econ-side routing table (the SAME table the markets `kalshi_econ.resolve` reads
+ — they agree by construction — but it does NOT import the markets package).
+- Pulls the first print via `history(..., vintages="settlement")`.
+- Builds the pairs frame with `knowledge_time = vintage_date` (the leakage
+ cutoff).
+- **Leakage guard:** when `as_of` is given, `assert_no_leakage` rejects any row
+ whose `knowledge_time > as_of` — a future revision can never leak into a
+ backtest (property-proven).
+
+## Labeled limitations (read these before you trust a number)
+
+The econ vertical is honest about four documented limits. None is a silent gap —
+each surfaces in the data or raises loudly.
+
+### 1. ALFRED first-print vintages are **day-granular** (the #1 landmine)
+
+The settlement-grade first print comes from FRED/ALFRED's realtime vintage store
+(BLS serves latest-revised only — it has no vintage endpoint). ALFRED's
+`realtime_start` is a **calendar date** (`YYYY-MM-DD`), so it **cannot resolve an
+intraday same-morning correction** (an 8:30 ET print vs a 9:45 ET correction on
+the SAME date collapse to one `vintage_date`).
+
+The Kalshi contract says 8:30→10:00 ET same-morning corrections DO count toward
+settlement, so for that narrow window ALFRED's `settlement_grade=True` means
+"first *date*-vintage per ALFRED" — equal to the true first print EXCEPT when a
+same-morning correction occurred. Every ALFRED-sourced row carries
+`vintage_precision="day"` so a consumer knows the vintage is day-exact, not
+intraday-exact. A release-day agency-scrape fetcher (intraday truth) is a
+deferred fast-follow, NOT in v1. Same-morning corrections are assumed rare (A4);
+the 29-10 live smoke spot-checks first-print ≠ latest-revised.
+
+### 2. Public venue history is **shallow** (~50–90 recent markets/series)
+
+The public Kalshi API surfaces only ~50–90 RECENT settled markets per series
+(oldest observed ~2026-05), and a market's candlesticks span its own ~1-month
+life. The FEDS-2026-010 first-contract history (2021–2023) is **NOT retrievable
+from the public endpoint** — a deep econ backtest needs the FEDS replication
+dataset or a running collector.
+
+`mostlyright.markets.econ_trades.candles` enforces this as a first-class behavior:
+a window entirely before the public-depth floor (~2026-05) returns an EMPTY
+DataFrame stamped `df.attrs["public_depth_limited"] = True` — never a fabricated
+deep candle. The `MAX_PUBLIC_DEPTH_NOTE` constant documents the realistic
+expectation. A window below the FEDS floor raises `DataAvailabilityError`.
+
+### 3. Trading-Economics-settled series ship an honest labeled proxy
+
+48 Kalshi series (KXUSPPI PPI-MoM, KXUSNFP, and international variants) settle
+against a **Trading Economics** value we cannot license. For those,
+`research_econ` uses the AGENCY first print as the value but labels the pair
+`settlement_grade=False` and raises a `DivergenceWarning` naming the series. It
+NEVER fabricates or approximates a TE value. The TE contract template lists TE as
+a fallback BELOW the agency ("first non-preliminary release" governs), so the
+agency first print is usually the same number TE republishes — the divergence is
+bounded but non-zero. Per-series, not per-family: within PPI, KXUSPPI (MoM)
+settles to TE while KXUSPPIYOY (YoY) settles to BLS.
+
+### 4. Keyless vs keyed behavior
+
+The default path is keyless and works for the primary venues; agency first-print
+fidelity needs free, opt-in keys.
+
+| Path | Key | Behavior |
+|------|-----|----------|
+| Kalshi trade-api v2 (series, candlesticks) | none | Full — public, no auth. |
+| Polymarket gamma + CLOB | none | Full — public, no auth. |
+| BLS CPI / Core / NFP / U3 / **PPI (`WPSFD4`)** | none (v1) | Latest-revised values, `settlement_grade=False`. `BLS_API_KEY` upgrades to v2 (higher limits) — still latest-revised. |
+| ALFRED first-print vintages | `FRED_API_KEY` (free) | Settlement-grade first print (`settlement_grade=True`, day-granular). **Keyless degrades**: `fetch_vintages` raises a documented `DataAvailabilityError` (never hits ALFRED blind) so the caller can fall back to BLS latest-revised provenance. |
+| Jobless claims (ICSA first print) | `FRED_API_KEY` (free) | Keyed → ALFRED-ICSA first release (`settlement_grade=True`). Keyless degrades to latest-revised. Either way a released window is non-empty. |
+| BEA GDP (advance/second/third) | `BEA_API_KEY` (free) | Estimate-type identifiable; advance is the first print (`settlement_grade=True`). GDP has NO keyless first-print source. |
+| Fed FOMC decisions | none (Federal Reserve Board H.15, NOT FRED) | Per-meeting target-rate midpoint + hike/hold/cut categorical (in `series_id`), `settlement_grade=True`. |
+
+Free keys: [FRED](https://fred.stlouisfed.org/docs/api/api_key.html) ·
+[BEA](https://apps.bea.gov/API/signup). Keys are read from the environment
+(or passed explicitly), placed only in the outbound request, and are NEVER
+logged, persisted to the cache, or embedded in an emitted row.
+
+## Live smoke test (pre-publish gate)
+
+`tests/test_econ_live_smoke.py` (`@pytest.mark.live`, excluded from CI) is the
+MANDATORY real-API gate before publish (development-workflow §4). It hits the real
+production endpoints with no mocks, exercises the full econ path, validates sane
+output, and prints a sample row per source for a human sanity-check.
+
+```bash
+# Keyless sub-paths (Kalshi + BLS + Polymarket) run with no keys:
+uv run pytest tests/test_econ_live_smoke.py -m live -s -v
+
+# Full coverage (closes A1 ALFRED fidelity, A5 BEA GDP, BLOCKER-3 jobless):
+export FRED_API_KEY=… # free — closes A1 + jobless first-print
+export BEA_API_KEY=… # free — closes A5
+uv run pytest tests/test_econ_live_smoke.py -m live -s -v
+```
+
+## TS Parity
+
+The `@mostlyrightmd/econ` TypeScript SDK mirrors the **public surface** —
+`history`, `releases`, `researchEcon`, and the `kalshiEcon` resolver — with an
+identical API and an adapted (browser-safe, no Node-only APIs) implementation.
+The TS surface parity + live/msw-recorded validation ships in the same phase
+(plan 29-09's vitest suite); this document is the shared reference for both SDKs.
+
+TS-specific notes:
+
+- The Python firewall regression (`test_firewall.py`) is Python-specific — the
+ four parity files it guards live in the Python `mostlyright.core` package. The
+ equivalent TS isolation is enforced structurally (the TS econ package has no
+ import of the TS weather/merge surface).
+- The live smoke here is the **Python** real-API gate; the TS live/recorded gate
+ for Kalshi/Polymarket lives in the 29-09 vitest suite. Each SDK validates its
+ own runtime.
+- No TS files change with this document.

The keyed live smoke (first real-API exercise of the Fed sub-path) exposed that
fetch_decisions() sent a bare parameterless GET to the H.15 DDP Output.aspx
(guaranteed HTTP 400) and then expected JSON — but the DDP serves only SDMX
XML/CSV of the EFFECTIVE funds rate; it carries no target range and no JSON at
all. The unit fixtures had modeled an invented payload (mock-verified assumption;
the exact failure class the mandatory real-API smoke rule exists to catch).
Fix, curl-verified against live federalreserve.gov (2026-07-09):
- fetch from the Board's canonical monetarypolicy/openmarket.htm rate-change
record (keyless, no params) via new parse_openmarket_html(): YYYY
year sections, Date|Increase|Decrease|Level(%) tables; handles the footnoted
2020-03-04 inter-meeting cut (March 4*), the pre-2008 point-target era
(Level '1.00'), and the ZIRP '0-0.25' integer-lower range; zero-decision /
garbage pages raise loudly (T-29-16), never parse as empty
- parse_decisions() payload contract + row-building reused unchanged
- FED_H15_URL -> FED_OPENMARKET_URL; effective-date/changes-only semantics
documented (hold meetings are not rows; meeting joins are research-layer)
- unit fixtures rebuilt from REAL page markup; live smoke Fed sub-path un-gated
from FRED_API_KEY (page is keyless) and no longer masks HTTP errors as skips
(only genuine network outages skip; a 4xx now FAILS)
Verified live: 59 decisions parsed; latest 2025-12-11 cut to 3.50-3.75
(midpoint 3.625, cross-checked against PRATES IORB 3.65). Closes A6.

source-identity contract
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
- series() is the canonical read; history() is a byte-identical silent alias
(Vu research()-style — docstring-deprecated, no runtime warning this release)
- source= contract §1: accepted {None,fred,bls,bea,dol,fed}; unknown source OR a
valid authority that cannot serve the indicator raises ValueError pre-network
- delivery= contract §2: live (default) | hosted -> SourceUnavailableError naming
ECON_HOSTED_URL + MOSTLYRIGHT_API_KEY (reserved seam); unknown -> ValueError
- new _snapshot.py: snapshot(indicator, *, as_of=None) returns the latest
settlement_grade vintage with vintage_date <= as_of; nothing knowable ->
IndicatorNotYetReleasedError
- research_econ() gains source=/delivery= forwarded to its series read;
default-call output byte-identical (core dataset() untouched — option-B deferred)
- 15 new TDD tests prove alias byte-identity, loud pre-network validation
(fetcher spy = zero calls), and snapshot as-of semantics

+"""Tests for ``econ.snapshot`` — the settlement-target state as-of a cutoff (29-11).

+
+When nothing is knowable at ``as_of`` (no settlement-grade vintage exists at or

+returns ``[]``/``None``. It accepts the SAME ``source=``/``delivery=`` kwargs as

Subject: [PATCH 33/73] feat(29-11): mirror econ source-identity surface in the
TS SDK
- new series.ts: canonical series() carrying the history.ts implementation +
source?/delivery? options with loud pre-fetch validation (mirrors Python's
_validate_source_and_delivery + _INDICATOR_SOURCE_AUTHORITIES map)
- history() is a byte-identical @deprecated alias (no runtime warning); history.ts
re-exports the canonical surface so existing ./history.js importers are unbroken
- new snapshot.ts: snapshot({ indicator, asOf?, source?, delivery? }) mirrors the
Python settlement-target semantics on the TS row types
- researchEcon.ts accepts + forwards source/delivery to its series read
- index.ts exports series/snapshot/history(@deprecated)/releases/researchEcon +
the new EconSource/EconDelivery/SeriesOptions/SnapshotOptions types
- 14 new vitest tests (8 series + 6 snapshot): unknown source throws with zero
fetch invocations, delivery:'hosted' -> SourceUnavailableError naming
ECON_HOSTED_URL, snapshot asOf before/after per Task 1. codegen --check
deterministic; typecheck + build green

hosted seam (ECON_HOSTED_URL + MOSTLYRIGHT_API_KEY) in §2. Vu's prose untouched
- CHANGELOG [Unreleased]: econ 1.13/1.14 source-identity conformance entry
(series() canonical, source=/delivery=, snapshot(as_of); dual-SDK)
- packages/econ/README.md: FRED ToU / data-source notices kept in sync with the

+ cross-vertical [`docs/source-identity.md`](docs/source-identity.md) surface it
+ was unified under: `series()` is the canonical read function (`history()` is a
+ byte-identical, docstring-`@deprecated` silent alias — no runtime warning this
+ release, warning next minor, removal at 2.0); `series()`/`research_econ()` gain
+ `source=` (contract §1 provenance: accepted `{None,"fred","bls","bea","dol",
+ "fed"}`, an unknown source OR a valid authority that cannot serve the indicator
+ raises `ValueError` **before any network call** — never a silent fallback) and
+ `delivery=` (contract §2: `"live"` default | `"hosted"` raises
+ `SourceUnavailableError` naming `ECON_HOSTED_URL` + `MOSTLYRIGHT_API_KEY`, the
+ reserved paid-tier seam); and a new `snapshot(indicator, *, as_of=None)` returns
+ the settlement-target state — the latest `settlement_grade=True` vintage with
+ `vintage_date <= as_of`, raising `IndicatorNotYetReleasedError` when nothing is
+ knowable. TS mirrors the whole surface (`series`/`snapshot`, `@deprecated`
+ `history` re-export, `source`/`delivery` options with the same loud validation).
+ The engine (fetchers/schema/cache/resolver/first-print logic) is untouched — a
+ default call is byte-identical to the pre-conformance output. Core's
+ `dataset()`/`research()` are **not** modified (an `include_econ` covariate seam
+ is an option-B question deferred to review); the econ↔weather firewall
+ (`test_firewall.py`) stays green.

+The **settlement-target state** of an indicator as knowable at `as_of`: the
+latest settlement-grade (`settlement_grade == True`) vintage whose
+`vintage_date <= as_of` (default `as_of`: now, UTC-aware), per period. This is
+the econ realization of the cross-vertical `snapshot` rule
+([source-identity §4](source-identity.md)) — "settlement-target state now": the
+current best settlement read of the thing a Kalshi contract settles on.
+
+```python
+# The current settlement-grade first print (what the market would settle against).
+snap = snapshot("cpi")
+
+# As-of a historical cutoff — only vintages knowable at that time are considered.
+snap = snapshot("cpi", as_of=datetime(2026, 6, 30, tzinfo=UTC))
+```
+
+- **Nothing knowable is an error, never empty.** When no settlement-grade vintage
+ exists at or before `as_of`, `snapshot` raises `IndicatorNotYetReleasedError` —
+ it NEVER returns `[]`/`None`.
+- A **post-expiration revision is never the settlement snapshot**: revisions carry
+ `settlement_grade=False` (Kalshi contractually excludes them), so the snapshot

Subject: [PATCH 36/73] fix(29-12): wire ALFRED first-print into BLS-family
read surface + coerce string dates
Closes the 29-VERIFICATION BLOCKER and a deeper latent bug it sat on top of.
BLOCKER (verifier-found): the ALFRED first-print fetcher (the ONLY settlement_grade=True
source for CPI/CPI-core/NFP/U3/PPI) was never reached from the read surface.
_fetch_bls_indicator called only bls.fetch (settlement_grade=False), so
history(cpi, vintages=settlement) and research_econ(KXCPI) raised for released periods.
Fix: keyed (FRED_API_KEY) routes to ALFRED realtime first prints via a live-verified
indicator to FRED-series map (cpi=CPIAUCSL, cpi_core=CPILFESL, nfp=PAYEMS, u3=UNRATE,
ppi=PPIFIS -- NOT BLS WPSFD4, which does not exist on FRED); keyless uses bls
latest-revised plus the settlement filter FRED_API_KEY-naming raise. Mirrors the working
dol pattern. Plus the two YoY dispatch defects: cpi_yoy to cpi, add cpi_core_yoy to cpi_core.
DEEPER latent bug (found by re-checking against the REAL API with string inputs -- the
class the verifier itself missed): the econ public surface raised TypeError for EVERY
string-date call since 29-08. series/history/research_econ/snapshot never coerced
ISO-string dates, yet strings are the documented primary usage. Every unit test used
datetime objects and the live smoke called fetchers directly, so nothing ever exercised
the surface the way users do. Fix: coerce str to date/datetime ONCE at each public entry
(_coerce_input_date in series, _coerce_as_of in snapshot). New regression tests assert
string inputs behave identically to datetime inputs across the whole surface.
Verified LIVE (real FRED key, string inputs): history settlement returns first-print
settlement_grade=True rows for all BLS-family indicators; research_econ went 10/14 failing
to all CPI/NFP/PPI/U3/jobless passing; snapshot(as_of) applies the cutoff correctly. GDP
correctly raises pending BEA key activation; Fed raises not-yet-released for a
no-rate-change window.

+implemented and live-proven but NEVER called by ``history``/``series``/

Adversarial-audit finding 1 (CONFIRMED blocker): GDP was orphaned from the read
surface. _fetch_gdp called bea.fetch_gdp, whose GetData response has no release
date, so bea.parse stamped vintage_date=now; _persist_rows partitions by
vintage_date, so every historical quarter misfiled into the current-month
partition and the historical read window found nothing -> series('gdp', past
window) raised IndicatorNotYetReleasedError. Every surface test monkeypatched
INDICATOR_FETCHERS['gdp'], masking the real round-trip.
Fix: route GDP first-print through the SAME unified ALFRED path the BLS family
uses. Two correctness points, both live-verified 2026-07-11:
- KXGDP settles on the ANNUALIZED GROWTH RATE, not the level -> FRED id is
A191RL1Q225SBEA ("Real GDP, Percent Change from Preceding Period"), NOT GDPC1.
Using the level would emit ~23500 instead of -0.3% (the GDP analog of the YoY
index-level bug). Its ALFRED realtime vintages ARE the advance/second/third
estimates with REAL release dates.
- 2025Q1 advance = -0.3% (release 2025-04-30); the advance is the first realtime
vintage -> settlement_grade=True with a real vintage_date that lands in the
correct partition. BEA stays the keyless latest-revised fallback.
gdp added to FRED_SERIES_BY_INDICATOR, _BLS_FAMILY_UNITS (percent), and
_FRED_UNLOCKABLE_INDICATORS. New surface regression test drives series('gdp')
through the REAL _fetch_gdp (asserts the FRED id is A191RL1Q225SBEA, not a level
or a BLS id) + research_econ('KXGDP') end-to-end.
Verified LIVE via the public surface (isolated cache, string inputs, real FRED
key): history('gdp',2025,settlement) returns advance rows -0.3%/3.0% with real
vintage_dates; research_econ('KXGDP') returns pairs. First of the 29-13 batches.

Subject: [PATCH 38/73] fix(29-13a2): keyless historical reads land in-window
(period-derived vintage_date, grade=False)
Adversarial-audit findings 5+6 (CONFIRMED): the keyless free tier (no FRED key)
was broken for historical windows. bls.parse/bea stamp vintage_date=knowledge_time
=retrieved_at (now); _persist_rows partitions by vintage_date, so a 2025 period
misfiled into the current-month partition and the historical read window found
nothing -> keyless history('cpi', 2025 window) raised IndicatorNotYetReleasedError
for a period released a year ago (isolated-cache repro confirmed). BEA additionally
mislabeled its latest-revised value settlement_grade=True.
Fix: _restamp_keyless() re-stamps every keyless latest-revised row before persist
with (a) settlement_grade=False (a keyless row is NEVER the settlement first
print) and (b) a period-derived vintage_date via _derive_release_vintage()
(monthly period + ~1mo, quarterly quarter-end + ~1mo; rounded LATER never earlier
for leakage safety), so the row lands in a period-aligned partition the read
window scans. Applied to both keyless branches (_fetch_bls_indicator, _fetch_gdp).
Settlement first-prints are untouched (ALFRED real realtime_start). Also lifted
`from datetime import UTC` to module scope.
Test fixes: the pre-existing test_ppi_dispatches_to_bls was the exact
mock-around-the-seam test the audit flagged -- it faked bls.fetch returning
settlement_grade=True/source="alfred" ("ALFRED first-print in the real path"),
asserting a grade the real bls path never produces, which MASKED the orphaned-
ALFRED blocker. Rewritten to keyless truth: bls -> settlement_grade=False/
source=bls.v1, read via vintages="all". New surface test proves keyless historical
returns period-filed rows (not raise) + settlement keyless raises naming
FRED_API_KEY.
Verified LIVE (isolated cache, no FRED key): keyless history('cpi'/'nfp'/'ppi'/
'gdp', 2025 window, vintages='all') returns period-filed rows (grade=False);
vintages='settlement' raises naming FRED_API_KEY. Full econ suite green.

Subject: [PATCH 39/73] fix(29-13c): fetch all ALFRED vintages so
vintages='all' returns every vintage (finding 12)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Adversarial-audit finding 12 (CONFIRMED): series(..., vintages='all') returned
only ONE vintage per period on the keyed path — _alfred_first_prints hard-coded
fetch_vintages(vintages='first'), so the cache only ever held first prints and
the read-time 'all' filter had nothing more to surface (confirmed live: max
vintages/period == 1).
Fix: _alfred_first_prints fetches vintages='all' (first realtime vintage per
period settlement_grade=True, each later revision False), window-filtered. The
read-time _filter_vintages then selects settlement (grade=True first print) vs
all. Two wins: vintages='all' now returns every vintage, and the cache is
complete so a later 'all' call after a 'settlement' call reads a full cache.
Verified LIVE (real FRED key): vintages='all' returns 66 rows / max 2 vintages
per period; vintages='settlement' returns the 6 first prints (all grade=True);
settlement is a subset of all. Full econ suite green.

Subject: [PATCH 40/73] fix(29-13b): source= actually routes to the pinned
authority (finding 11)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Adversarial-audit finding 11 (CONFIRMED): the source= pin was validated then
ignored — routing was decided solely by FRED_API_KEY presence, so source='bls'
with a key returned ALFRED rows and source='fred' without a key silently degraded
to BLS, contradicting docs/source-identity.md §1 ("pins provenance, never a silent
fallback").
Fix: thread source through the fetcher dispatch and honor it —
- _fetch_bls_indicator / _fetch_gdp: source='fred' forces ALFRED (raising
SourceUnavailableError naming FRED_API_KEY when no key — never a silent BLS/BEA
degrade); source='bls'/'bea' forces the agency latest-revised path even when a
key is present; source=None keeps the ALFRED-if-keyed-else-agency default.
- gdp authorities extended to {bea, fred} (GDP first print now comes from ALFRED).
- series(): a PINNED source fetches FRESH from the routed authority and returns
those rows directly — it does NOT round-trip through the cache re-read (which
build_econ_dataframe/read_econ_window normalize the per-row source to
"econ.cache", erasing provenance) and does NOT persist (so a pin never
contaminates the default cache). The returned frame is stamped with the pinned
authority's real source tag, so the pin SURFACES provenance (bls.v1/alfred/...)
instead of the uniform econ.cache. source=None keeps the cache flow unchanged.
(A first attempt filtered the cache re-read by source tag; reverted because the
cache normalizes per-row source to econ.cache — fetch-fresh-for-pinned is the
correct design.)
Updated the injected-fetcher test fakes (4 files) to the (from, to, *, source)
dispatch signature.
Verified LIVE (real FRED key, isolated caches): source='bls' -> 12 rows
grade=False source=bls.v1; source='fred' no-key -> SourceUnavailableError naming
FRED_API_KEY; source='fred' key -> 6 rows grade=True source=alfred; source='bea'
for cpi -> unservable ValueError; source=None default unchanged. Full econ suite green.

Subject: [PATCH 41/73] feat(29-13d): compute YoY contracts as the true
12-month % change (finding 9)
Adversarial-audit finding 9 (CONFIRMED): KXCPIYOY/KXCPICOREYOY/KXUSPPIYOY settle
on the year-over-year PERCENT change, but the dispatch remapped each YoY indicator
to its base LEVEL series and returned the raw index (e.g. 317.7 instead of 2.9%)
labeled settlement_grade=True -- a silent wrong settlement value. Operator decision
2026-07-11: compute YoY properly.
New _yoy.py: compute_yoy() derives yoy[P] = 100*(index_firstprint[P] /
index_firstprint[P-12mo] - 1) from the base index first-print vintages, emitting
value=percent, units="percent", inheriting P's provenance (vintage_date/grade so
the YoY becomes knowable when P's index first print releases). _fetch_yoy() widens
the base fetch back 12 months so each in-window period has its year-ago
counterpart, then window-filters. Dispatch: cpi_yoy/cpi_core_yoy/ppi_yoy ->
_fetch_yoy (was -> base level).
Methodology (documented, first-print-to-first-print): the agency's released YoY
uses the year-ago base as of release day; for the lightly-revised CPI/core-CPI/PPI
indices these three contracts cover, that differs from the first-print base only by
small seasonal-factor revisions, typically within Kalshi's one-decimal settlement.
NFP-YoY (heavily revised) is not a contract, so the approximation is
settlement-appropriate for the three YoY markets.
Verified LIVE (real FRED key) against reality: cpi_yoy 2.86/3.04/2.80/2.37...%
(matches actual 2024-25 CPI YoY), cpi_core_yoy ~3.1-3.3%, ppi_yoy ~2.6-3.7% -- all
units=percent, in-range, NOT the ~300 index level. New test_yoy.py (hand-computed
3.0% through the real dispatch) + updated two YoY wiring tests. Full econ suite green.

Subject: [PATCH 42/73] feat(29-13f): port compute_yoy + BEA/DOL-ICSA/Fed
agency fetchers to TS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Mirror the Python econ fetchers so all 12 indicators have a live path:
- yoy.ts: compute_yoy (12-month % change from base first-print vintages),
units=percent — closes the YoY index-level bug class (finding 9).
- fetchers.ts: fetchIcsa (ALFRED-ICSA keyed first print / FRED keyless
latest-revised, parity with dol.py), fetchBea (NIPA T10101 GDP % change,
keyless-BEA fallback), fetchFed + parseOpenmarketHtml + parseDecisions
(federalreserve.gov openmarket.htm year-sectioned rate-change parser — Fed,
NOT FRED), and fredKeyPresent().
- Add ECON_SOURCE_BEA/DOL/FED source-identity tags (parity with _schema.py).

Subject: [PATCH 43/73] feat(29-13e): route econ dispatch through FRED ids +
register all 12 indicators
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Close the adversarial-audit BLOCKER (findings 2/3/4): defaultFetchRows sent BLS
ids (WPSFD4/CUUR0000SA0 — which do NOT exist on FRED) to fetchAlfred, so the TS
settlement path was broken. Now:
- Add FRED_SERIES_BY_INDICATOR (cpi:CPIAUCSL, cpi_core:CPILFESL, nfp:PAYEMS,
u3:UNRATE, ppi:PPIFIS, gdp:A191RL1Q225SBEA — the growth-rate series, mirrors
the Python map EXACTLY). fetchAlfred receives the FRED id; BLS ids stay only
for the keyless fetchBls fallback.
- Mirror the keyless period-derived vintage_date + grade=false re-stamp so
keyless historical reads land in-window (finding a2).
- Exhaustive 12-indicator dispatch (findings 7/8/10/13): cpi/cpi_core/nfp/u3/ppi
via ALFRED-or-BLS; cpi_yoy/cpi_core_yoy/ppi_yoy via compute_yoy (percent); gdp
via ALFRED growth-rate or BEA; jobless_claims via ALFRED-ICSA; fed_funds/
fed_decision via openmarket.htm. No generic 'no fetcher registered' Error.
- source= routing into the default path (fred/bls/bea authorities), gdp
authorities widened to {bea,fred}.
- Keyless-settlement gap names FRED_API_KEY as the unlock (finding 13).
- Export FRED_SERIES_BY_INDICATOR from the package index.

Subject: [PATCH 44/73] test(29-13): injected-transport dispatch parity tests
for the econ vertical
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Drive the REAL defaultFetchRows dispatch (no injected fetchRows; mock only the
globalThis.fetch transport) and assert the external id/host that actually reaches
the wire — the test style that catches the BLOCKER bug class:
- cpi -> ALFRED series_id=CPIAUCSL (never CUUR0000SA0); ppi -> PPIFIS (never
WPSFD4); gdp -> A191RL1Q225SBEA (never GDPC1).
- all 12 indicators dispatch without the generic 'no fetcher registered' Error.
- cpi_yoy returns units=percent + the computed 12-month % (not the index level).
- fed_funds hits federalreserve.gov/monetarypolicy/openmarket.htm (never a FRED
host) and parses the target-range midpoint.
- jobless_claims -> ALFRED series_id=ICSA with realtime vintages.
- keyless cpi settlement throws an error naming FRED_API_KEY (finding 13).

Subject: [PATCH 45/73] docs(29): make the FRED-practically-required nuance
explicit + fix stale GDP-source row
The keyless/keyed section predated 29-13 batch A (GDP re-routed through ALFRED
A191RL1Q225SBEA). Corrected: GDP settlement first print comes from FRED/ALFRED, not
BEA advance; BEA is only a keyless latest-revised fallback. Made explicit that
'keyless' != 'settlement-grade' -- zero keys gives latest-revised BLS + Fed only,
and the free FRED key is the practical requirement for first-print settlement across
CPI/NFP/U3/PPI/GDP/jobless. Flagged the pending FRED cache carve-out (D-LIC-2).

+### 4. Keyless vs keyed behavior — the free FRED key is the practical requirement for settlement
+
+Every source is free, but **"keyless" and "settlement-grade" are not the same
+thing.** With **zero keys** you get latest-revised BLS values (NOT the settlement
+first print) plus Fed decisions; the **free** `FRED_API_KEY` is what unlocks the
+settlement-grade first prints — which is the whole point of this vertical.
+
+| Path | Zero keys | + free `FRED_API_KEY` |
+|------|-----------|------------------------|
+| Kalshi trade-api v2 (series, candlesticks) · Polymarket gamma + CLOB | Full — public, no auth | — |
+| Fed FOMC decisions (Federal Reserve Board `openmarket.htm`, **NOT FRED**) | Full, `settlement_grade=True` (per-meeting midpoint + hike/hold/cut in `series_id`) | — |
+| CPI / Core / NFP / U3 / **PPI (`WPSFD4`)** + their YoY | BLS latest-revised, `settlement_grade=False`; a `vintages="settlement"` read raises `IndicatorNotYetReleasedError` naming `FRED_API_KEY` | ALFRED first print, `settlement_grade=True` (day-granular) |
+| GDP (annualized real growth) | **unavailable without a key** * | ALFRED first print of `A191RL1Q225SBEA`, `settlement_grade=True` |
+| Jobless claims (ICSA) | **unavailable** — DOL's machine path is bot-walled (403); the bytes come from FRED | ALFRED-ICSA first release, `settlement_grade=True` |
+
+\* `BEA_API_KEY` (also free) adds only a **keyless GDP _latest-revised_ fallback**
+(`settlement_grade=False`); GDP's settlement first print comes from FRED/ALFRED, so
+with a FRED key you never need BEA. `BLS_API_KEY` (free) only raises the BLS v1→v2
+rate limit — still latest-revised.
+
+**Bottom line:** all sources are free public APIs; the **free FRED key is the
+practical requirement for first-print settlement** (CPI/NFP/U3/PPI/GDP/jobless); Fed
+decisions and latest-revised BLS work with no keys at all. Free keys:
+[FRED](https://fred.stlouisfed.org/docs/api/api_key.html) ·
+[BEA](https://apps.bea.gov/API/signup). Keys are read from the environment (or
+passed explicitly), placed only in the outbound request, and are NEVER logged or

FRED's Terms of Use prohibit storing/caching/archiving FRED content (Prohibitions
(q); API (l) — .planning/research/DATA-LICENSING.md). The econ parquet cache was
persisting alfred + dol.icsa (FRED-transported) rows, which facilitates a ToU
violation. This is a pre-publish blocker.
Fix (write chokepoint + fetch-through):
- _schema.py: FRED_DERIVED_SOURCES = {alfred, dol.icsa}.
- _cache.py write_econ_cache: per-ROW filter BEFORE the econ.cache re-stamp (so
origin is knowable) drops FRED-derived rows unless MOSTLYRIGHT_PERSIST_FRED=1;
agency rows (bls/bea/fed — public domain) in the same call still persist; logs an
informative INFO line.
- _history.py series(): FETCH-THROUGH — when persist is a no-op because the rows
were FRED-derived-skipped, use the freshly-fetched rows directly (stamping the
requested indicator, which the cache would normally apply) rather than raising
IndicatorNotYetReleasedError. "0 rows persisted" != "not released".
Tradeoff (documented): FRED-derived indicators (CPI/NFP/U3/PPI/GDP/jobless
settlement) become fetch-through per session; opt in with MOSTLYRIGHT_PERSIST_FRED=1
(informed consent, mirroring the delivery="hosted" opt-in posture).
Tests: new test_cache_licensing.py (skip-by-default alfred + dol.icsa; opt-in
persists; mixed-call persists agency only; INFO log; history fetch-through returns
rows with cache empty; README FRED-disclaimer regression guard). The two
cache-MECHANICS files (test_cache, test_history) opt into PERSIST_FRED=1 in their
fixtures (they test caching with alfred sample rows; licensing is covered here).
Verified LIVE (real FRED key): default cpi settlement -> 6 rows via fetch-through,
0 parquet files on disk; PERSIST_FRED=1 -> 6 cached; fed (public domain) -> 56
cached with no opt-in. Full econ suite green.
Note: docs/econ-vertical.md updated (carve-out now implemented, not "pending").
Remaining pre-publish: BLS API ToS manual read; D-LIC-4 (CLAUDE.md pointer +
REVIEW-DISCIPLINE checklist).

Cross-model (Codex/GPT-5) review of the PR. Python-side fixes:
- CRITICAL C1 (key leak): fred_alfred.py + bea.py called response.raise_for_status()
on a URL carrying api_key=/UserID=; httpx embeds the full request URL in the
HTTPStatusError message → the live key leaked into any log/traceback. Now catch
the status and raise SourceUnavailableError with the BARE endpoint constant
(mirrors dol.py). Regression: assert the key substring is absent from str(exc).
- HIGH H1 (partial-cache silent gap): series() default path only fetched when the
cache was fully EMPTY, so a superset window (Jan-Mar cached, ask Jan-Jun) dropped
Apr-Jun silently. Added a fetched-window coverage ledger (_cache.py
is_window_covered/mark_window_covered, .coverage.json sidecar); fetch when the
window isn't covered. Fetch-through (FRED, not persisted) does NOT mark covered.
- HIGH H2 (over-read past to_date): read_econ_window returned every row in the
overlapping MONTH partitions with no per-row vintage_date filter — a weekly
jobless window pulled vintages after to_date (leakage-adjacent). Added a
vintage_date-in-[start,end] filter.
- HIGH H3 (frame_source mislabel): the D-LIC-2 fetch-through branch left
frame_source="econ.cache", so genuinely-live ALFRED rows were labeled cache-read.
Now carry the fetched rows' real source into the frame (verified live: cpi -> alfred).
- HIGH H4 (keyless jobless doomed request): keyless dol.fetch_initial_claims sent
api_key="" to FRED (rejected). Now fail FAST pre-network with DataAvailabilityError
naming FRED_API_KEY when there's no key AND no injected client/fred_fetch.
- HIGH H5 (GDP period format): keyed ALFRED GDP stamped period "2026-04" while
keyless BEA stamps "2026Q2" for the same quarter. Normalize the keyed GDP rows to
"YYYYQ#" (verified live: 2024Q4/2025Q1/2025Q2).
- MED M1 (pinned indicator): the pinned-source path returned fetcher rows without
normalizing the indicator (ALFRED tags the FRED series id; fed.py hardcodes
fed_funds). Stamp the requested indicator on the pinned path (as the cache/
fetch-through paths do). Fixes source="fed" for fed_decision + pinned gdp.
- MED M2 (bea default grade): bea.parse() defaulted a no-hint fetch to
advance/settlement_grade=True; now settlement_grade requires an explicit advance
hint (the exported parse() is safe standalone; keyless prod path re-stamps False).
Full econ suite green; 6 new regression tests + updated the bea/dol expectation tests.
TS-side findings (C2/C3/C4/H6 + TS halves of H4/H5) follow in a paired commit.

Codex CRITICAL C2. core's fetchWithRetry interpolates the FULL request URL
into every thrown error's .message on status >= 400. The econ ALFRED / ICSA /
BEA call sites pass URLs carrying api_key= / UserID=
in the query string, so the live key leaked into any log / error-tracker that
recorded the message. We must NOT touch the shared http.ts (other verticals use
it), so each econ call site now wraps fetchWithRetry in try/catch and re-raises
a SourceUnavailableError carrying ONLY the BASE endpoint constant (no query
string) + the HTTP status; the caught message is never propagated. Mirrors the
Python fred_alfred.py / bea.py status-catch -> bare-URL raise (f70cb9c).
Regression: a forced 401 on the keyed CPI (ALFRED), keyed jobless (ICSA), and
keyless-FRED GDP (BEA UserID) paths asserts the key substring is present in the
outbound URL but absent from the thrown error's message / toString / structured
dict / url.

Codex CRITICAL C3. researchEcon built a settlement pair as
{...row, settlementGrade: resolution.settlementGrade}, but the schema field
inherited from the spread is snake_case settlement_grade. A Trading-Economics-
settled pair therefore reported settlement_grade === true (WRONG — the inherited
agency vintage grade) while only the non-standard camelCase settlementGrade read
false. Now overwrite the canonical settlement_grade with the contract-level grade
(camelCase kept as a byte-identical alias), mirroring the Python _research.py
(pairs["settlement_grade"] = bool(rule.settlement_grade)).
Regression: researchEcon("KXUSPPI") over the REAL dispatch (injected transport
returns an in-window ALFRED/PPIFIS first print with row-level settlement_grade
true) asserts the resulting pair.settlement_grade === false; the KXCPIYOY pair
asserts the canonical field agrees with the camelCase alias (true).

Codex CRITICAL C4. defaultFetchRows called fetchIcsa() / fetchFed() with ZERO
args, discarding fromDate/toDate — so 3 of 12 indicators returned ALL history
on every call. That breaks assertNoLeakage for any historical asOf (post-window
vintages leak) and silently bloats every non-asOf result. The sibling BLS / YoY
/ GDP helpers already windowFilter their output; TS has no cache layer to apply
the vintage_date read filter the Python path gets for free. Now windowFilter the
fetchIcsa / fetchFed output at the dispatch, keyed on vintage_date.
Regression: series("jobless_claims", 2026-06-01..06-07) against a 3-week fixture
(vintage before / inside / after the window) returns only the in-window week;
series("fed_funds", June window) against a June+September fixture returns only
the June meeting.

Codex HIGH H6. parseDecisions hardcoded indicator: FED_INDICATOR (fed_funds)
regardless of whether fed_funds or fed_decision was requested, and TS has no
cache re-stamp — so series("fed_decision", …) always returned rows tagged
fed_funds. parseDecisions/fetchFed now accept an optional indicator, threaded
from the dispatch, and stamp it on the row's indicator field. The categorical
stays encoded under the fed_funds: series_id namespace (the documented
convention decisionOf reads), mirroring the Python re-stamp that overwrites only
the indicator field (M1).
Regression: series("fed_decision") rows carry indicator === "fed_decision"
(series_id still fed_funds:); series("fed_funds") is unchanged.

Codex HIGH H5. periodFromObsDate only handles monthly (day==01 -> YYYY-MM), so a
quarterly ALFRED GDP obs date (2026-04-01) became period "2026-04" while keyless
BEA emits "2026Q2" for the same quarter — a cross-source period mismatch that
breaks joins. fetchGdp's keyed ALFRED branch now maps the period through a new
monthlyToQuarter helper (mirrors the Python _monthly_to_quarter applied in
_fetch_gdp), leaving already-quarterly / non-monthly forms untouched.
Regression: a keyed GDP fixture (obs date 2026-04-01) reports period "2026Q2".

Codex HIGH H4. Keyless fetchIcsa omitted api_key and sent a doomed request that
FRED rejects (jobless_claims has no keyless source: the DOL CSV is bot-walled and
the FRED ICSA fallback needs a key). Now mirror the Python dol.fetch_initial_claims
fail-fast: with no FRED_API_KEY throw DataAvailabilityError(source_404) naming
FRED_API_KEY BEFORE any network call. The keyless request-building and the now-
unreachable latestRevisedIcsa selector are removed (a keyless value was never a
first print). A test wanting the keyless parse/label path injects rows via
series({ fetchRows }), which bypasses this fetcher.
Regression: series("jobless_claims") with no key rejects with DataAvailabilityError
naming FRED_API_KEY and asserts globalThis.fetch was never called.

Codex LOW L1. The TE-divergence path did an unconditional console.warn — a library
console write a consumer can't silence, violating the no-bare-console TS
convention. The divergence is already carried by the honest pair label
(settlementGrade=false) and the structured onDivergence callback, so the bare
write is removed; onDivergence is now the only side-channel (docs updated).
Regression: a TE-settled researchEcon call invokes onDivergence once and asserts
console.warn was never called; the existing KXUSPPI test now checks the structured
event instead of console text.

Round 2 verified round-1's fixes landed, but found 6C+3H — two CRITICALs were
bugs the round-1 H1 coverage-ledger introduced:
- CRITICAL (self-inflicted) — coverage ledger marked the ENTIRE requested window
covered on any fetch, freezing a future-extending window forever (re-running
"this year's CPI to date" never picked up new releases). Now cap the marked
range at `now` (a fully-past window hits the cache; a future window stays
uncovered past now and re-fetches as time advances).
- CRITICAL (self-inflicted) — the ledger was route/grade-blind: keyless-cached
(grade=False) data marked a window "covered", so a later keyed vintages=settlement
read short-circuited to the cache → raised IndicatorNotYetReleasedError instead of
running ALFRED. Ledger is now GRADE-AWARE (settlement flag per interval; a
settlement read is only satisfied by a settlement-capable fill).
- CRITICAL — Python _fetch_jobless_claims ignored from/to and returned the FULL
ICSA history (the Python counterpart of the TS C4; worse because jobless is
FRED-derived → fetch-through, bypassing read_econ_window's window filter). Now
window-filtered.
- HIGH — pinned-source reads (source=bls/bea/fed) + several default keyless
branches bypassed windowing (returned the whole year/history). Window-filter EVERY
non-ALFRED fetcher branch (_fetch_bls_indicator BLS, _fetch_gdp BEA, _fetch_fed,
_fetch_jobless_claims) — _restamp_keyless gives period-derived vintage_dates so
the vintage-date window applies uniformly.
- HIGH — transport-level httpx.RequestError (timeout/connection) was unsanitized in
all 4 fetchers (the key sits on exc.request). Wrap client.get/post → sanitized
SourceUnavailableError with the bare endpoint (`from None` drops the httpx exc).
- HIGH — invalidate_econ deleted the parquet partition but not the coverage ledger,
leaving the window "covered" and un-refetchable (also the only escape hatch from a
mis-marked ledger). Now clears coverage under the lock.
- MEDIUM — resolve_settlement (econ + markets) prefix-matched without a delimiter
check, so "KXCPIENERGY" silently routed to "KXCPI". Now require "-" or exact.
Verified LIVE (real keys): pinned source='bls' windowed to 3 rows; 9/9 indicators
green; research_econ('KXCPI') 9 pairs. Full econ+markets suite green; 7 new tests.
TS round-2 findings (C4 parseBea grade, H5-TS pinned window, H6-TS fetchBls, M10-TS)
follow in a paired commit.

Subject: [PATCH 56/73] =?UTF-8?q?fix(29):=20C4=20(TS)=20=E2=80=94=20keyles?=
=?UTF-8?q?s=20BEA=20parseBea=20defaults=20to=20settlement=5Fgrade=3Dfalse?=

parseBea() defaulted an un-hinted row to release_type="advance" →
settlement_grade=true, the INVERSE of the Python M2 fix. fetchGdp() calls
fetchBea({ yearRange }) with no releaseType/vintageDate — the only keyless GDP
path — so every raw keyless-BEA GDP row was mislabeled settlement-grade, though
BEA bulk GetData is latest-revised data (never the advance first print).
Mirror Python bea.py: compute settlement_grade = (resolvedType === "advance")
BEFORE defaulting the label (undefined → false), then default release_type to
the neutral non-first-print "revised" (a valid enum). An explicit
releaseType="advance" still opts in. parseBea/fetchBea are exported +
independently callable, so the raw parser must be safe even though the
series-level fetchGdp restampKeyless also forces grade=false downstream.
Test: fetchBea keyless fixture (real transport → parseBea, unmasked) →
settlement_grade=false + release_type="revised"; direct parseBea guards for the
no-hint and explicit-advance cases.

fetchBlsIndicator's non-ALFRED (keyless BLS) branch and fetchGdp's non-ALFRED
(keyless BEA) branch returned the whole year/history — unlike the sibling
alfredFirstPrints / fetchYoy / jobless / fed branches, they never called
windowFilter. Since TS has no cache layer to apply a vintage-date read filter,
a sub-year — or, worse, a DEFAULT keyless — request leaked every out-of-window
row.
Apply windowFilter(restampKeyless(rows), from, to) to both branches, mirroring
the Python round-2 _fetch_bls_indicator / _fetch_gdp fix. restampKeyless already
stamps period-derived vintage_dates (first-of-month after the observation period
for monthly; quarter-end + 1mo for quarterly), so the same vintage-date window
the ALFRED path uses bounds these rows uniformly.
Test: series("cpi", June window) keyless over a 3-month BLS fixture → only the
2026-05 row (derived vintage 2026-06-01) survives; series("gdp", July window)
keyless over a 3-quarter BEA fixture → only 2026Q2 (derived vintage 2026-07-01).

raiseSanitizedTransportError wrapped fetchAlfred / fetchIcsa / fetchBea but NOT
fetchBls, whose POST body carries BLS_API_KEY (registrationkey). A transport
error (connection/timeout) propagated raw as core's TherminalError
("fetch failed after N attempts: "), which would surface any request
detail the transport echoed into the error.
Wrap fetchBls's fetchWithRetry call in the same try/catch → raiseSanitizedTransportError
with the BARE endpoint (the key lives in the body, never the URL), mirroring the
Python bls.py _post_with_retry wrap and the sibling fetchers.
Test (fake timers to burn the retry backoff): a forced transport rejection whose
message inlines the key throws a sanitized SourceUnavailableError whose surfaces
(message/toString/stack/dict/url) never contain the key. Verified RED without the
wrap — pre-fix the raw TherminalError (message carrying the key) propagated.

kalshiEconResolve's longest-prefix loop matched on ticker.startsWith(root) with
no delimiter check, so "KXCPIENERGY" silently routed to the "KXCPI" root instead
of raising the intended unroutable-ticker error.
Require the char after the matched root to be the dated-ticker delimiter "-" (an
exact full-ticker match is already handled by the earlier exact branch), so a
longer uncatalogued series that merely shares a prefix falls through to the
EconTickerError throw. Mirrors the Python _settlement_map.resolve_settlement (and
markets kalshi_econ) round-2 guard. Longest-wins is preserved: KXUSPPIYOY-26JUL
still binds to KXUSPPIYOY (next char "-"), not the shorter KXUSPPI (next char "Y").
Test: "KXCPI-26JUL" resolves to KXCPI; "KXCPIENERGY" throws EconTickerError; the
exact "KXCPI" still resolves; "KXUSPPIYOY-26JUL" still binds the longer root.
Verified RED without the guard — pre-fix "KXCPIENERGY" resolved silently.

_derive_release_vintage(indicator, period) now checks the curated release
schedule FIRST and returns the exact scheduled release_datetime (gdp 2026Q2 ->
2026-07-30 12:30 UTC) instead of the heuristic 1st-of-release-month, which
stamped a date BEFORE the real release and leaked an unreleased period into a
mid-month window. The heuristic remains the fallback for out-of-table periods
(the curated table is partial), preserving the 29-13 partition-landing.
- thread indicator through _restamp_keyless -> _derive_release_vintage
- tests: scheduled-date lookup, out-of-table heuristic fallback, keyless GDP
window exclusion of an unreleased quarter (unit + end-to-end)

The persisted-window coverage cap used datetime.now(UTC).date(), which marked
the incomplete CURRENT day covered — a fixed past to_date reaching today would
freeze and never see a later same-day release. Cap at now - 1 day instead: the
current day is incomplete (releases still land today), matching the weather
current-period-incomplete discipline. A window ending on/before yesterday is a
fully-elapsed period and still hits the cache on repeat.
- tests: a window ending today re-fetches both calls (count==2); a control
ending yesterday hits the cache on the second call (count==1)

The docstring claimed an un-hinted row defaults to release_type="advance" /
settlement_grade=True, but the code (correctly, per round-2 C4) defaults to
"revised" / False and only grades "advance" for an explicit/inferable hint.
Rewrite the two bullets to match the actual behavior (mirrors the TS parseBea
comment) so the stale doc can't re-invert the fix if trusted.

deriveReleaseVintage(indicator, period) now checks releases(indicator) FIRST and
returns the scheduled releaseDatetime (gdp 2026Q2 -> 2026-07-30) instead of the
heuristic 1st-of-release-month, which leaked an unreleased period into a mid-month
window. The heuristic remains the out-of-table fallback. Byte-semantic mirror of
the Python C1 fix (documented anti-drift pair).
- thread indicator through restampKeyless -> deriveReleaseVintage
- update the two round-2 H5 assertions that pinned the heuristic vintage
(2026-06-01 -> 2026-06-10 cpi; 2026-07-01 -> 2026-07-30 gdp) — same windowing,
now the REAL scheduled date
- new tests: scheduled-vintage inclusion + look-ahead exclusion (throws
IndicatorNotYetReleasedError)

escaped as a raw core TherminalError instead of the documented
SourceUnavailableError the other four econ fetchers raise. Wrap it via
raiseSanitizedTransportError (openmarket.htm carries no key, so this is a TYPE
normalization, not key-sanitization). Mirrors the Python H1 fix.

Codex round 4 (CONVERGED) flagged that M2 fixed parse()'s docstring but missed
the identical stale claim in fetch_gdp()'s own Args docstring — it still said an
un-hinted single-estimate fetch is treated as "advance", the exact inversion the
round-2 C4 code fix corrected (un-hinted bulk GetData is latest-REVISED data →
defaults to "revised", settlement_grade=False). Doc-only; a future maintainer
trusting the stale text could reintroduce the settlement-grade inversion. Now
mirrors parse()'s corrected wording and the TS parseBea comment.

Codex round 4 (CONVERGED) empirically caught a Python↔TS parity divergence in the
keyless-vintage HEURISTIC FALLBACK (the tier below the round-3 calendar consult,
unchanged by round 3): JS Date.UTC(2026, 14, 1) silently rolls '2026Q5' over to
2027-04-01, where Python's strict date() rejects month 3*q / m outside [1,12] and
returns None. A bogus rolled-over vintage_date is a silent temporal misfile.
Not reachable via real fetchers today (BEA emits Q1-4, BLS emits 01-12) — a
defensive boundary guard (validate external data at the boundary). deriveReleaseVintage
now rejects quarter outside 1..4 and month outside 1..12 before Date.UTC, returning
undefined to mirror Python's None exactly.
Tests: Python parity anchor (test_codex_review_round4.py — the private returns None
for 2026Q5/Q0/2026-13/-00, valid extremes Q4/12 still resolve) + a TS end-to-end
regression through the real keyless BEA series() dispatch asserting no 2027 rollover.
Full econ+markets (Py) + full TS suite + typecheck + codegen --check all green.

Subject: [PATCH 69/73] test(29): pin the clock in the round-4 TS parity test
(codex R5 LOW)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Codex round 5 (CONVERGED) noted the new test's window relied on real wall-clock
'now' falling inside it — a latent bump-before-2028 time-bomb. Fake ONLY Date
(toFake:['Date'], leaving real timers so the async fetch can't wedge) pinned to
2026-07-15 and tighten the window to [2026-01-01, 2026-12-31]: the un-derived row
keeps its now-deterministic retrieved_at vintage and survives; the pre-fix
2027-04-01 rollover would fall outside the window and drop the row, so the length
assert alone discriminates. Deterministic forever, no window maintenance.

The keyed BEA GDP smoke asserted the RAW un-hinted bulk fetch_gdp() identifies an
advance/second/third release_type. That was a FALSE GREEN: it passed only because
un-hinted rows USED to default to 'advance' — the exact CRITICAL codex round-2 C4
fixed (bulk GetData is latest-REVISED, not the first print). Post-C4 the bulk call
correctly labels every row 'revised'/settlement_grade=False, so the test began
failing against the live API — a test-vs-code contradiction the mocked suite hid
(mocks inject a release_type hint; the live bulk call has none).
Rewrite to assert the THREE live-verified real behaviors, so the smoke now GUARDS
C4 instead of contradicting it and genuinely closes A5 (GDP first-print IS
identifiable):
- production settlement path: history('gdp', ..., vintages='settlement') routes
through ALFRED (A191RL1Q225SBEA) → release_type='advance'/settlement_grade=True
with real release-day vintages (the REAL KXGDP settlement mechanism);
- raw BEA inference: fetch_gdp(vintage_date='2025-04-30') → 2025Q1 infers
'advance'/True (infer_release_type against a live BEA payload);
- un-hinted bulk: fetch_gdp(year_range=...) → all 'revised'/False (the C4 contract).
Verified LIVE (real FRED+BEA keys): 11/11 econ live-smoke pass. 2025Q2-2026Q1
settlement GDP all advance/True (values 3.0/4.3/1.4/2.0).

Subject: [PATCH 71/73] style(29): clear ruff lint so the required fast-suite
CI gate passes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The branch was never pushed until now, so this is its first CI run — 7 accumulated
ruff errors (never caught locally; pre-commit hooks aren't installed in this
working copy) failed the required fast-suite check on all 3 Python versions:
- F401 unused typing.Any (test_codex_review_round2)
- RUF002 en-dashes in a docstring (test_codex_review_round4: 'Q1-4'/'01-12')
- RUF022 unsorted __all__ (fed.py, _schema.py) — autofixed
- SIM110 for-loop → any() in _cache.is_window_covered (semantically identical)
- RUF001 en/em-dash in fed.py rate-range normalization — # noqa (the dashes are
INTENTIONAL: openmarket.htm writes '4.25-4.50' with an en-dash; the replace() is
load-bearing, so suppress rather than break parsing).
No behavior change. Full ruff check clean; econ suite green.

Subject: [PATCH 72/73] fix(29): register econ delivery='hosted' seam in the
D-28.2 grep-gate + ruff format
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Two more first-CI-run gaps (branch never hit CI until this PR):
- Hosted-call grep-gate (scripts/check_no_hosted_calls.py) flagged econ's
delivery='hosted' references in _history/_research/_snapshot. These are the
reserved OPT-IN seam — they validate-and-RAISE (SourceUnavailableError naming
ECON_HOSTED_URL), never a hosted call on the default path — exactly the pattern
the weather seam files are already allowlisted for. Registered the 3 econ
seam-bearing files in _SEAM_FILES (the gate's own sanctioned mechanism) and
corrected the stale comment that claimed econ 'can never trip RULE 2'.
- ruff format --check flagged 8 econ/markets files committed across the codex
rounds without formatting applied. Whitespace-only; no behavior change.
All three pre-test fast-suite gates now pass locally (ruff check, ruff format
--check, hosted-call gate); the pytest step was already green (exit 0).

Subject: [PATCH 73/73] style(29): ruff-format _history.py (missed in the prior
format commit)
_history.py was reformatted by 'ruff format .' alongside the other 8 files but
left unstaged in 03b116a. Whitespace-only; commits the same required
ruff-format --check compliance so the fast-suite format gate passes.
