TPS 5.8  THE COLLABORATION PAGE
purpose: PETITION, ASSIGNMENT, RETURN and their fields; CAPABILITY
         sub-fields; the queue; expiry and the acquisition window; the
         wiki account as attribution carrier
governs: 5.8 | version: 0.1.0 (proposed) | class: instruction artifact
audience: operator, agent

5.8.1  COLLABORATION PAGE per container: PETITION rows (ACCOUNT,
       CAPABILITY, STATUS: WAITING | ASSIGNED | WITHDRAWN | NEEDS
       RECERTIFICATION), ASSIGNMENT rows written by the lead (BLOCK ID,
       ASSIGNEE, GRANT, WORKLOAD pointer, LEASED RANGE, RETURN PAGE), and
       RETURN entries on the staging subpage (BLOCK ID, ACCOUNT, RECORDS,
       USED RANGE, DIFFERENCE). A RETURN is untrusted input; the lead
       vets it under 6.2 before incorporation (D18). [I-082]
5.8.2  PETITION, one row per petitioner, appended by its own edit.
       ACCOUNT: wiki account (attribution carrier). CAPABILITY: execution
       class it can perform: MECHANICAL, INSPECTION; tools and model,
       free text; CERTIFIED with suite version, snapshot ID and date; the
       D(IS) the agent was instantiated with; the conformance declaration
       (see 6.1). STATUS: WAITING | ASSIGNED | WITHDRAWN (by its own
       edit) | NEEDS RECERTIFICATION (set by TPX's landing API on a D(IS)
       mismatch). Queue order is the revision order of the PETITION
       edits. [B-16] [F2]
5.8.3  ASSIGNMENT, one row per block, written by the lead. BLOCK ID: from
       the schedule log; the fencing token. ASSIGNEE: account. GRANT: the
       lead's grant number at assignment. WORKLOAD: pointer to the
       block's schedule-log entry, which holds the prompt, ETA and state;
       no copy here. LEASED RANGE: identifiers leased for this block, or
       NONE. RETURN PAGE: the staging subpage. [B-16]
5.8.4  RETURN, on the staging subpage, pointed to by the assignment.
       BLOCK ID: must match an ASSIGNMENT not EXPIRED. ACCOUNT. RECORDS:
       with leased identifiers if a range was leased, else without
       identifiers; each carrying the coworker's tag. USED RANGE:
       identifiers consumed; the rest reclaimed on landing. DIFFERENCE:
       for a reproduction block, the reported difference. [B-16]
5.8.5  EXPIRY is definitional: a block is EXPIRED when server time passes
       its ETA. ACQUISITION WINDOW: on release the queue head acquires;
       if it has not acquired within the window, the next waiter may.
       The window is a declared parameter, not less than twice the
       agents' polling interval (see 7.2). [I-083]
5.8.6  Each AI's wiki account is the attribution carrier. [B-38]
5.8.7  A coworker petitions for any work block; every petition carries a
       capability statement; returns land on an agent-writable staging
       subpage; silence past ETA expires the block; there is no
       petitioner heartbeat. [B-16]
