-Claude Code, Codex, and OpenCode manage their own native CLI session and resume
-state. qmax-code mirrors successful interactive turns into its in-memory
-history, but `--save-session` does not replace a CLI backend's native resume
-mechanism.
+Switching models, effort levels, or providers preserves one shared conversation.
+Claude Code, Codex, Antigravity, and OpenCode reuse their native session when
+available; returning to a backend transfers the turns it missed. Built-in
+Anthropic, Cerebras, and Ollama receive the shared history, including exposed
+CLI tool activity. `/save`, `/resume`, and `--resume` retain this state across
+restarts. `--resume last -p "continue the review" --save-session` also works.
+
+The retained transcript is separate from the model's compacted working context.
+Large conversations use a private, searchable JSONL file plus recent context;
+the destination agent can retrieve older details with its file tools. Provider
+context windows still apply. Hidden reasoning and provider-private state cannot
+be transferred, and image interpretation depends on the destination's support.
+Only content exposed to qmax-code can be retained; this cannot recover history
+that an older version already discarded.
+
+Saved conversations live in `~/.qmax-code/sessions/`; those carrying a portable
+transcript are kept for 90 days, legacy sessions for 7. `/clear` resets the
+shared conversation and native resume state and starts a new session ID, so the
+conversation you cleared stays listed by `/sessions` and remains resumable.
+Save errors are reported.
+If a native session is rejected by its CLI, the failed turn remains in the
+transcript and the next request restores portable context into a fresh session.
Cloud session sync is opt-in:

+
+## Local Conversation Retention
+
+Saved conversations include user/assistant messages, tool inputs and outputs
+exposed to qmax-code, and native CLI session identifiers and workspace paths.
+They do not collect hidden reasoning, provider configuration, or credentials
+from the environment. Switching providers makes retained conversation content
+available to the newly selected provider.
+
+Session writes use an owner-only temporary file and atomic replacement.
+Portable transcripts in `~/.qmax-code/sessions/` are reclaimed after 90 days;
+legacy sessions keep the seven-day cleanup. Large handoffs and built-in
+compaction use an owner-only temporary directory containing a searchable
+transcript. These temporary files are removed on clear, on normal exit, and on
+the `Ctrl+C` / `SIGTERM` exit paths; only an uncatchable kill (`SIGKILL`,
+power loss) can leave them in the OS temporary directory.
+
+Structured credential fields are redacted before saving or transferring
+archived content, along with unambiguous credential shapes in prose. Retained
+content is redacted more conservatively than displayed content: it is replayed
+as the conversation itself, so an over-eager match would silently corrupt the
+only copy of your context. Redaction is best effort, not a substitute for
+keeping secrets out of prompts and tool output. Turning off
+auto-save prevents automatic qmax session writes, including on exit; `/save`
+still writes explicitly. Native CLIs manage their own persistence independently.
