Store information in SAIHM persistent memory. Encryption happens in this process and the key never leaves it, so the server holds ciphertext it cannot read. Use this when a fact, decision, or piece of context should outlive the current session. Pass an existing cellId to update that cell instead of adding a new one. Returns the cell id that saihm_forget takes.

Retrieve your memories from SAIHM and decrypt them in this process; the server never sees plaintext. Use this at the start of a session, or whenever past context is needed. Pass query to filter by keyword, or leave it out to load everything. To read a single cell another agent shared with you, pass their sharerPinnedAgentIdHashHex and sharerRecord together with the cellId; that path is read-only.

Cryptographically erase one memory by its cell id (GDPR Art. 17). Destroying the wrapped key leaves the content unreadable to everyone, the operator included. Irreversible: use it when erasure is the intent, not to tidy a working set.

Show the current SAIHM session: the agent identity, which this client derives locally, plus the tier, custody mode, shard and sharing counts, and bfsi score the server reports. No plaintext appears, because the server holds none. Use it to check which identity is active and what is stored and shared.

Grant one other agent access to a single memory cell, named by cellId. Identify the recipient by their recipientPinnedAgentIdHashHex, pinned out-of-band, and their recipientRecord. Set scope to 'read', 'write' or 'readwrite'. Only that one cell is exposed, and sharing re-wraps its key rather than copying the memory.

Withdraw a grant made with saihm_share, naming the same cellId and the recipient's recipientHex. It applies to future reads and cannot retract what the recipient has already read. Use it to end access; the memory itself remains, and saihm_forget is what erases.

Open a protocol governance proposal: set scope to 'emission_param' or 'protocol_upgrade', and for 'emission_param' also pass paramKey and proposedValue. Protocol governance is not enabled for this client yet — the tool is present so the surface stays stable, and calling it returns a 'governance unavailable' error rather than opening a vote.

Cast a vote on an open protocol governance proposal by its proposalId, with approve set to true to approve or false to reject. Protocol governance is not enabled for this client yet — the tool is present so the surface stays stable, and calling it returns a 'governance unavailable' error rather than recording a vote.

Activate free SAIHM persistent memory for this agent. Call this when the user asks to join, sign up for, or set up SAIHM. It self-generates a sovereign memory key on this device and starts a one-time human approval — the tool returns a URL and short code for the user to open and enter. After the user approves, call saihm_join again to finish; the memory tools then work. No payment and no website visit.
