Gud Boi 1da9b760a3 Preserve IB history request bounds on no data
Complete HMDS no-data replies without silently retrying a day
older. Let `open_history_client()` classify the original request
and leave frame stepping to `start_backfill()`.

Distinguish `request_end_dt` from `oldest_shm_dt` so the first
frame after an empty interval retains its unwritten end bar.
Inline the storage time cutoff and drop the unused two-direction
`diff_history()` helper. Explain both dates and filtering rules.

Add request-boundary tests and real SHM/NativeDB regressions:
all 2,004 supplied bars survive, while the closure stays empty.

AI Prompt I/O Log — codex

This directory tracks prompts and outputs for AI-assisted development using Codex. Substantive contributions include model identification, prompt context, output records, and human contribution accounting.

Code output uses Git diff references; non-code output is retained in the paired .raw.md file. Human contributors remain responsible for review and acceptance. Entries follow the NLNet generative AI policy.
