Source documentation does not establish software or physical hardware qualification. See the support and qualification records for their exact scope.

Historical documentation and version migration

Legacy HAL/OSAL/Kconfig pages describe old directories, interfaces, instance generation and ownership. They cannot govern current typed factories, static instances or borrowing lifetimes. This page gives old URLs an explicit version boundary; it never silently interprets old function names as current public APIs.

Continue with the current platform

Legacy content	Current entry	Must recheck
HAL factory/device interfaces	Current API, configuration and factory	Generated IDs, readonly faces, cold lookup and platform lifecycle
OSAL	OS waiting and shutdown, current OS API	Backend differences, static storage, deadlines, publishers and join
Kconfig platform/peripheral/OS macros	Configuration reference, migration guide	One authored TOML, immutable IR, rejection rules and exact mode
Old build/flash tutorials	First build, support scope	Actual tool versions, Board, SDK and artifact identities
Historical software counts or pass records	Exact evidence entry	Original source, scope and receipts; documentation updates inherit no qualification

Migration changes configuration, interface access, storage ownership and shutdown together, then revalidates the migrated source and assembly. Old parameters, object IDs and neighboring configuration results do not transfer to a new bundle.

Obtain frozen historical material

docs/archive/sphinx-before-next-generation/ and docs/archive/implementation/ preserve historical source and original numbering. They stay outside current default site search and establish no current capability or qualification. Select a specific Git commit to browse or download old source:

• Legacy Sphinx source: frozen documentation planning baseline 0111c8d3

• Historical RF implementation source: the same frozen baseline

This fixed revision identifies historical bytes only; it does not grant historical firmware qualification to that revision. Old locale PO files are historical translations, not reviewed current translations selected automatically by the language selector. For offline historical reading, obtain the fixed Git snapshot above. The current documentation package provides migration explanations and legacy URL aliases without adding every historical tutorial to current search or reinterpreting its contract.

How old addresses are handled

The URL migration table lists legacy RST paths, languages and target pages. Old en/ and zh_CN/ addresses remain separate. Public site root api/index.html is a historical API boundary entry directing readers to confirm the version before choosing migration guidance; it cannot silently mean the current API. Current public APIs live within an immutable version at the site-relative path versions/<release_id>/api/index.html, or at api/index.html under an extracted offline package root. Always identify the enclosing version root when interpreting an address. Legacy HAL/OSAL/Kconfig paths with different semantics enter this page to establish their version boundary before migration. Equivalent entries from the preceding simplified Sphinx site can enter corresponding current pages. Aliases are local HTML with relative links, without JavaScript, CDN or external redirection services.

The page migration and authority map records source pages, authority, reader tasks, actual site destinations and retention rules. Preserve original contract and result paths, linking originals or derived views rather than creating a second status or specification authority. Subsequent path changes update mappings, navigation, aliases and offline checks together.
