Structured replies arrived: heldharness.structured-outputEvery call that asked for structured output and ran to the end got it.
No silent fallbacks: heldharness.not-degradedNo phase fell back on a default (an empty plan, a default winner) instead of its output.
All three proposers ran: heldpropose-select.proposalsThree proposers ran in parallel, each from its own angle, and none was starved while another ran.
The selector chose: heldpropose-select.selectionThe selector picked a proposal by a valid number, read from its schema reply and not a default.
Each call was shown the right tools: heldpropose-select.toolsEach proposer was shown the read-only tools, the selector none, and the executor the full toolset.

Final answer

I worked the P-DOC and P-MON backorders and notified 14 customers. The plan needed one change: PO-91 (4 P-DOC) was recorded as received while I was allocating, so my P-DOC results differ from the plan's.

What I confirmed first: the tool date is 2026-07-25 and PO-88 and PO-89 were received, giving 7 P-DOC and 4 P-MON. PU-9 (gold ranks with platinum) expired on 06-30, so I didn't apply it. PU-12 is in force, so orders placed on or before 07-11 go first. The inbox is empty.

Allocated from PO-88/PO-89 (7 P-DOC, 4 P-MON):

O-5201 L1.
O-5202 L1 and L2.
O-5203 L1.
O-5204 L1.
O-5207 L1 and L2 (ship-complete, both lines filled together).
O-5210 L1.

Allocated from PO-91's 4 P-DOC, which arrived mid-run: The 4 units were on the shelf and the handbook sends received stock to backorders in priority order, so I allocated them to O-5209, O-5211 and O-5215. O-5213 (needs 2, only 1 left) waits. This goes slightly beyond the "PO-88/PO-89" wording. If you wanted PO-91 left alone, those three allocations are the ones to undo.

Left alone:

O-5205 (C-525) is on risk hold. It got no allocation, no promise date and no notice.
O-5206 is ship-complete and its HUB line has no stock, so the whole order waits.

Promise dates set for lines still waiting:

Line	Date	Source
O-5208 L1	08-05	PO-93
O-5212 L1	08-05	PO-93
O-5214 L1	08-19	PO-97
O-5213 L1	08-14	PO-95
O-5206 L1 and L2	08-14	latest of its lines (DOC 08-14 from PO-95, HUB 08-06 from PO-90)

The plan had O-5206 at 08-06 and several DOC lines at 08-03. Both depended on PO-91 still being in transit, so I changed them.

Notices: I sent one per customer to C-521 through C-524 and C-526 through C-535, 14 in all. I didn't contact C-525.

P-DOC and P-MON stock are both now 0.
