* feat(sdk): always persist media facts and ship facts-first replacements for legacy Media* surfaces
PR 1 of the media legacy retirement program (audit-frozen, 4 PRs).
- Every media-bearing user turn now persists normalized __openclaw.media
facts unconditionally while continuing to emit the legacy top-level
Media* projection byte-identically (dual-write bridge; the conditional
shouldPersistStructuredMediaEntries gate now always includes media).
- New replacement APIs, shipped before any removal: typed hook media
facts (media[], originalMedia[], mediaStagingPending) on message
events; {{AttachmentPath}}/{{AttachmentUrl}}/{{AttachmentContentType}}/
{{AttachmentDir}}/{{AttachmentIndex}} template variables; focused
openclaw/plugin-sdk/media-local-roots subpath split out of the
deprecated agent-media-payload facade.
- Every legacy surface carries @deprecated naming its replacement, under
one named compatibility record media-legacy-projection with the
operator-approved removeAfter 2026-10-01 (two release trains; deletion
additionally gates on a clean published-plugin artifact sweep).
- Generic transcript append invariant documented; SDK migration, hooks,
and configuration docs updated to the facts-first path.
Writer golden matrix proves legacy bytes and model prompt bytes are
unchanged while nested facts become unconditional. 2,189 broad media
tests green; SDK api-baseline regenerated on fresh-env Testbox.
* feat(sdk): register media-local-roots subpath exports and deprecation metadata
Completes PR 1: package export map for openclaw/plugin-sdk/media-local-roots
plus the deprecated-subpath inventory and doc metadata entries for the
media-legacy-projection record.
* chore(sdk): track media-local-roots entrypoint and deprecated-export budgets
* fix(sdk): keep deprecated MSTeams buildMediaPayload re-export through the compat window
Deleting shipped runtime-api re-exports belongs to retirement PR 4 after
the media-legacy-projection window; PR 1 only deprecates. Also formats
the migration-guide schedule table.
* docs: regenerate docs map for media migration additions
* feat(channels): batch 1 producers drop media placeholder bodies
Media-placeholder program batch 1: Google Chat, Zalo, LINE, and
Mattermost stop minting <media:kind> placeholder bodies. Media-only
messages carry an empty caption plus one structured fact per native
attachment (type-only when a download fails or is rejected, so payload
positions and kind signals stay aligned). The shared
formatMediaPlaceholderText SDK formatter renders text-only carriers
(Mattermost pending-room lines) from structured facts; per-channel
placeholder builders and the expected-count side channel are deleted.
* fix(mattermost): satisfy type, deadcode, and SDK manifest gates
