FIXED 2026-07-02: the original version of this file (inherited verbatim from the old, never-actually-live td-params-server) looked for {PARAMS_DATA_DIR}/{symbol}/{date}.json but real published data on Corsair is actually laid out as {PARAMS_DATA_DIR}/{TD_EA_CODE}/{symbol}/{date}.json (confirmed against data/params/TrendDegree1/USDJPY/2026-06-26.json, which predates and survived this fix). The old code would have silently returned UNKNOWN_SYMBOL for every real request - never caught before because nothing had actually gone live against it yet. FIXED 2026-07-04: two related bugs found once a real EA actually polled this in production, both now fixed together: 1. The current-week check used `start <= today < end` (strict less- than on the end date) - excluding the week's own final day from counting as "current." A week published through Friday would stop being served starting ON that same Friday, hours before it actually ended. Now `start <= today <= end` (inclusive). 2. Trading weeks are now uniformly Saturday-Friday across ALL instruments (see Lightning's week_utils.py) so that 24/7 instruments (crypto) get the same real weekend gap to run walk-forward and publish that 5-day instruments always had. But that gap still needs bridging: a new week's params might not be published the instant the old week ends. Rather than fail NOT_AVAILABLE during that gap, this now explicitly falls back to the most recent PAST published week if no current week exists - "keep trading last week's params until this week's are ready" - with MAX_PARAMS_AGE_DAYS as the only thing that cuts this fallback off (refuses to serve something dangerously stale as if it were still usable). Selection priority (in order): 1. A week containing today (start <= today <= end) - the ideal case. 2. The most recent PAST week (end < today) - explicit stale-but- known fallback, gated by MAX_PARAMS_AGE_DAYS. 3. The nearest UPCOMING week (start > today) - kept for the edge case of publishing ahead of a week's start; rarely hit under the new Sat-Fri model since publishing typically happens on or after the Saturday a week begins, not before. 4. None -> NOT_AVAILABLE. UPDATED 2026-07-10: field_mapping.py's published doc shape changed - instrument scaling fields (point, contract_size, price_decimals) and dd_calibration's contents changed, but trade_week_start/trade_week_end remain top-level (unchanged) since the EA's own freshness gate reads them directly from there. No change was needed in this module after all - noted here in case a stale comment elsewhere suggests otherwise.
