# Free sample — Proof Lag Incident Playbook

**Skill ID:** `gf-po-proof-lag-incidents`  
**Unlock:** $8.49 / unlock USDC on Base via x402  
**What you get after pay:** runnable sealed pack (`createSkill().run`) + workbook + templates  

## Summary

Incident playbook when payment proof, unlock receipts, or chain confirmation lag behind buyer expectation on marketplace paths.

Proof lag is a trust incident, not a support FAQ. This pack covers detection, buyer comms, temporary unlock policy, reconciliation, and chain/provider lag SLIs. Free outline first; x402 sealed unlock. Not legal advice; no settlement guarantees.

## When to use

- Buyers report paid-but-not-unlocked while mempool, indexer, or webhook confirmation is delayed beyond your stated window.
- Support and ops disagree on whether to manual-unlock during lag, creating inconsistent trust outcomes.
- You need SLIs for proof lag that separate chain delay, indexer lag, and application webhook failure.

## Decision-grade outline (free)

1. Classify lag sources: chain confirmation delay, indexer lag, x402 facilitator delay, webhook drop, and local fulfillment race conditions.
2. Instrument proof-lag SLIs: time from payment intent to unlock grant, p50/p95, and alert thresholds per payment rail.
3. Run incident actions: freeze related deploys, enable temporary grant policy with dual control, and open a reconciliation queue.
4. Communicate with buyers using templates that avoid overpromising finality while offering concrete check intervals and ticket IDs.
5. Close with reconciliation: match on-chain or facilitator receipts to grants, reverse false grants, and file root-cause tickets with owners.

## Capabilities

- Lag source classification tree for chain, indexer, facilitator, and app races
- Proof-lag SLI definitions from payment intent to unlock grant
- Temporary grant policy with dual-control and reconciliation hooks
- Buyer and internal comms templates for lag incidents
- Reconciliation close-out checklist for false grants and missing unlocks

## Detailed description

When a buyer has paid and the unlock has not appeared, every minute is a trust incident. Proof Lag Incident Playbook treats delayed payment proof and unlock receipts as first-class reliability events rather than scattered support tickets. Classification separates chain confirmation delay, indexer lag, x402 facilitator delay, webhook drops, and local fulfillment races so responders pick the right lever. SLIs measure time from payment intent to unlock grant with p50/p95 and rail-specific alert thresholds, so “crypto is slow” is no longer an unmeasured shrug. Incident actions freeze related deploys, optionally enable a dual-controlled temporary grant policy, and open a reconciliation queue that must close every manual grant. Buyer communications set check intervals and ticket IDs without inventing finality guarantees the chain cannot keep. Close-out reconciliation matches facilitator or on-chain receipts to grants, reverses false positives, and files root-cause work with owners. A free outline ships on the listing; the sealed pack unlocks via x402 on Base with USDC. Operational trust guidance only—not legal advice, not a payment processor, not financial advice, and it makes no guarantees of settlement speed, dispute outcomes, or revenue. Use it so proof lag has a commander path and a paper trail.
