Lesson 96: Post-Override Rollback Verification Packet - SLA Proof, Store Telemetry Reconcile, and Override Row Closure

Direct answer: A post-override rollback verification packet is the evidence bundle you assemble after any Lesson 95 window to show that the pre-authorized rollback Lesson 93 row (rollback_message_id_ref) published within SLA, that player-visible surfaces match the hashed copy, and that the override row ends in closed_verified or a renewed Lesson 94 freeze when facts are still dirty.

What this lesson solves

Overrides are noisy. Regulators and partners do not care about your war-room deck; they care whether reality matched what you promised to walk back. This lesson turns rollback into auditable completion, not a Slack reaction emoji.

Prerequisites: A consumed or expired override_event_id, a drafted rollback_message_id_ref, and read access to store CMS timestamps plus at least one CRM or support export. Expected time: about ninety minutes including a tabletop on a late rollback with healthy telemetry.

What you will build

  1. lesson78_post_override_rollback_verification_packet_policy.md (contract below)
  2. lesson78_post_override_rollback_verification_packet.csv (one row per verification cycle)
  3. A checklist job that runs at valid_to_utc + rollback_sla_minutes

Step 1 - Define verification gate classes

gate fail signal default posture
V1 – SLA miss rollback_published_at_utc − override_send_completed_at_utc > rollback_sla_minutes open incident; extend Lesson 94 hold on all related bundles
V2 – Hash mismatch live page HTML hash ≠ signed_message_body_hash on rollback row fail closed; republish from vault
V3 – Telemetry contradiction store wishlist/refund spike crosses telemetry_contradiction_threshold while rollback claims “stable” escalate; do not close override
V4 – Open override revoke_state still pending after verification window auto-flag finance + legal

Step 2 - Author lesson78_post_override_rollback_verification_packet_policy.md

Minimum sections:

  1. Purpose – prove rollback happened and matched the rehearsed hash before you declare the train healthy again.
  2. SLA clock – default thirty minutes after override send completes for first-party blog/email; fifteen minutes for store cards when pricing language was touched.
  3. Evidence sources – CMS revision ids, CDN ETag, app store console “live” timestamp, partner portal ack id.
  4. Telemetry window – compare sixty minutes before rollback to sixty minutes after; store baseline from the same weekday prior week to dampen seasonality.
  5. Closure states – closed_verified, closed_with_new_freeze (append new Lesson 94 row), failed_open (override remains hot).
  6. Retention – archive HTML, CSV extracts, and hashed screenshots for two annual audit cycles or your DPA max.

Step 3 - Author lesson78_post_override_rollback_verification_packet.csv

column purpose
verification_packet_id stable id
override_event_id_ref Lesson 95 row
rollback_message_id_ref Lesson 93 rollback bundle
rollback_sla_minutes policy value used
override_send_completed_at_utc when optimistic copy finished
rollback_published_at_utc first live hash match
sla_met_flag true / false
live_page_hash sha256 of canonical HTML
telemetry_delta_json compact JSON of key metrics
closure_state closed_verified / closed_with_new_freeze / failed_open
verification_evidence_hash sha256 over prior columns + signer ids

Step 4 - Execute verification (45 minutes)

  1. Lock send time from mail or CMS logs; if fuzzy, use earliest CDN hit.
  2. Pull rollback artifact from vault; publish or confirm already live.
  3. Hash the public URL with the same canonicalization rules as Lesson 93 signing.
  4. Pull telemetry; tag anomalies with source_system.
  5. Decide closure – if V3 fires, open a fresh Lesson 94 freeze with a cited kill_switch_event_id; do not “wait and see.”

Step 5 - Tabletop - rollback on time but refunds spike

Rollback text is accurate, but macro refunds contradict the calming banner. Outcome: V3 blocks closed_verified; move to closed_with_new_freeze and schedule a new Lesson 92 pass.

Pro tips

  • Screenshot the footer – store pages strip metadata; capture the footer hash block for disputes.
  • Pair with Lesson 91 – if the spike matches a mismatch class already in the rollup packet, cite that row id in telemetry_delta_json.
  • Don’t average away pain – use medians for latency metrics, sums for refunds; mixing invites false greens.

Troubleshooting

symptom likely cause fix
SLA false pass using draft preview URL hash production host only
Hash ok but players angry localized bundle not rolled back verify per-locale rows
Telemetry APIs lag polling too early wait one full analytics pipeline delay

Common mistakes

  • Closing the override because “we posted an apology tweet” without hash proof.
  • Using gross revenue instead of net of refunds when rollback promises stability.
  • Letting marketing edit rollback after sign—K4 from Lesson 94 still applies.

FAQ

What if rollback never needed to publish because override failed upstream?

Log closure_state=closed_verified with rollback_published_at_utc equal to override abort time and sla_met_flag=true only if abort happened before window expiry.

Does this replace support macros from Lesson 84?

No. Macros route humans; this packet proves global copy state.

Who signs verification_evidence_hash?

On-call live-ops lead plus analytics delegate; split duty from Lesson 95 signers when possible.

Lesson recap

Verification is where promises meet receipts. Without SLA and hash proof, rollback language is just another marketing paragraph.
