 M6 补充：remote history response parser 现在接受 JSON:API `included` collection，会过滤非事件资源，并递归解包 `resource`/`attributes`/`properties` 后用外层 resource id 作为事件 ID fallback。
 
 M6 补充：remote history `data`/`payload`/`response`/`result`/`body` 等 event-list 字段现在也接受单个 SDK event 对象，避免非数组单事件页被当作普通 wrapper 后丢失。

 - 本轮补充：transcript resume 的嵌套 content block 接受 `toolUseId`/`toolUseID`、`isError`、`cacheControl`、`cacheReference` 字段别名，并保留 cache edit 的 `cacheReference`。
 - 本轮补充：transcript resume 的 nested content block `id`/`tool_use_id`/`toolUseId` 现在接受 JSON number，并保留为字符串 tool-use ID。

 - `internal/memory`: session-memory recall and relevant-memory model selectors now also unwrap provider-style `choices`, `outputs`, `candidates`, and `generations` responses plus top-level `message`/`content`/`text` envelopes, recovering JSON selection payloads from nested `message.content`, content-block arrays, `content.parts[].text`, and fenced `json` code blocks.
 - `internal/memory`: model-backed memory fact extraction now also unwraps provider-style `choices`, `outputs`, `candidates`, and `generations` responses plus top-level `message`/`content`/`text` envelopes, recovering JSON facts payloads from nested `message.content`, content-block arrays, `content.parts[].text`, and fenced `json` code blocks.
 - `internal/session`: remote-history response parsing now also unwraps provider-style `choices`, `outputs`, `candidates`, and `generations` responses plus top-level `message`/`content`/`text` envelopes, recovering event page JSON plus pagination from nested `message.content`, content-block arrays, `content.parts[].text`, and fenced `json` code blocks.
+- `internal/session`: remote-history pagination now accepts `starting_after`/`startingAfter`/`after*` cursor aliases from page fields and link URL query parameters when deriving the next `before_id`.
 - `internal/session`: project session listing and pagination, prompt-history lock/buffered flush/field aliases, lightweight transcript index/title/text-preview inference, line-offset transcript indexing/window/byte-budget-window/parent-chain/resume/tail/byte-budget-tail loading, AI-title/last-prompt/task/agent/PR/worktree transcript metadata loading and type/field aliases, transcript message/session UUID field aliases, tombstone metadata loading with target/session/reason aliases and delete/relink replay, agent-scoped content replacement metadata/record field-alias loading, session-scoped metadata reappend including AI-title/last-prompt/task-summary, streaming transcript search snippets for resume/search UI, official `subagents/agent-*.jsonl` transcript layout with legacy sidechain listing, agent metadata sidecar read/write/field aliases, sidechain runtime start/append/finish/cancel/fail summary bridging plus parent-chain append/finish, sidechain manager orchestration for spawn/append/finish/cancel/fail/list/resume, sidechain state/list/resume support with content-field aliases, sidechain resume context construction, sidechain conversation and agent-scoped content-replacement reconstruction, transcript tail/window loading and byte-budget tail loading for bounded-memory resume/UI paths, lightweight transcript metadata loading, remote-history token refresh retry, page-field/event-list/records/entries/last-id/cursor/event-id/has-next aliases plus wrapped-data/links/paging/bare-array/keyed-event-map responses, before_id resume, fallback field fill, and duplicate-aware parent linking during transcript materialization.
 - `internal/session`: transcript full loader and line-offset index now accept top-level record UUID aliases such as `messageUuid`, `messageUUID`, `message_id`, `messageId`, and `id`, plus parent message UUID/ID aliases for progress bridge and indexed resume paths.
 - `internal/session`: indexed resume chains now distinguish budget-truncated parents from genuinely missing parents, exposing both markers while preserving bounded transcript reads.
