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       CAPABILITY, STATUS: WAITING | ASSIGNED | WITHDRAWN | NEEDS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 | SUSPENDED), 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 STATUS: WAITING | ASSIGNED | WITHDRAWN (by its own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) | SUSPENDED (set by TPX on a failed canary and cleared
       only by the declaring authority's declaration; see 5.14, 5.18).
       Queue order is the revision order of the PETITION edits. [B-16]

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]
5.8.8  Under a CLOSED access policy TPX refuses a petition row from an
       account not on the UWC's access list (see 5.16). [I-153] [D52]
