Which state offices sit in each district and upazila, what services each portal lists, and what is the freshest dated notice per portal?

Field presence. Part of what the twin can answer. Every figure below is the value the route serves, with its source; the raw response is at /api/twin/brain/field.

Descriptive, sourced: no model

Basis: sourced records (URL, sha256 or locator per row), no model.

Offices are the stored officers pages, bound to the registry by exact domain and to a district by exact host suffix against the observed district portals. Notices and services are the items printed on the stored home pages. Counts are over held rows only.

Where these figures come from

The source collections

Source	Publisher	Unit	Caveat
District, upazila, office, ministry and directorate portal home pages (stored copies)	Publisher: each portal's own gov.bd site, stored by the BPL crawlers	Unit: one row per portal host (the fuller parse where two collections hold it)	Caveat: A home page shows the notices and services the portal chose to show on the date stored; `observed_on` is the stored file, whose bytes the sha256 covers. Offices whose home page is not held appear in the officers inventory only.

Not held

Union portal offices, services and notices: The unions tree (15 GB, 98k files) is the unions brain's (BRN33) input; the FIELD lane already serves union documents. This route links to it by name instead of re-reading the tree.
Person-notice titles: Leave, passport-NOC, posting, retirement and obituary titles name individuals; the build withholds the title and keeps date, href and subject.
Offices with no stored page: Registry field offices whose site is not among the stored homes or officers pages are not counted; the inventory is the offices held, not the state's footprint.
