Buffer Pool

The permanence reserve. A share of every issuance is withheld from circulation to cover reversal — storm damage, bleaching, coastal erosion, habitat loss. The share is fixed per methodology family, not negotiated per project. Issuance detail is at /registry/issuance.

Buffer policy

Withholding rates are set per methodology family and are not adjusted per project: F01 20%, F02 25%, F03 15%, F04 10%, F05 20%. Buffer units are serialised and held in BUFFER status on the unit ledger; they are not in circulation and cannot be transferred or retired while held.

Three columns, three different records. “Family rate” is what the methodology family attracts. “Withheld” is what the batch record says was held back at issuance. “BUFFER on ledger” is how many units actually carry BUFFER status today. On the batches above these do not all agree — rows marked * were withheld at a share other than their family rate, and the ledger count differs from the withheld figure on several batches. Both gaps are shown rather than smoothed over: the reserve is a solvency claim, and a solvency claim that is only reported through its most flattering source is not one.

Releases. No buffer release has been recorded. Release requires independent permanence verification and Registry Manager approval; none has been made.

Per-project risk assessments underlying the reserve are held in the registry but are not published here; the recorded quantities do not currently reconcile with the batches they refer to, and they will not be published until they do.
