From c94edbce44b93642de3be82450df570972b13169 Mon Sep 17 00:00:00 2001 From: Dennis Thiessen Date: Wed, 26 Aug 2026 09:17:47 +0200 Subject: [PATCH] fix(citadel): apply Tier 1 relevance fixes, JD coverage 51% -> 68% All three Tier 1 items from the critique, all honestly available, no claim altered. The R2 vocabulary now appears where R2 is actually evidenced: the SW-7 bullet carries ingestion and lifecycle, and SW-1 carries transformation and storage. R2 was the single core responsibility scored Direct, and the document had been proving it in substance while missing it in the JD's own words. SW-2 now names the Oracle/Kafka/Python/Teradata estate a distributed system he operates - not one he designed, which stays a gap. The second skills line is relabelled "Distributed systems" and names distributed databases explicitly, closing the fifth preferred-technology hit that Phase 0 counted as Direct but the resume never actually wrote. Recorded what was deliberately not added, because raising keyword coverage is exactly where a later run would be tempted to overreach: "scalable" is an unverified scale claim, and SDK, high-throughput, data-intensive, simulation, model development and self-service have no canonical evidence. Verified still absent after the edit. Scope kept to what was approved. The user said "tier 1 fixes", so the Tier 2 headline retitle - "Production Data Platforms on AWS", the line most likely to draw the opening challenge from a technical reviewer - was left in place for them to decide. Validator PASS with zero warnings: the 58% cadence warning cleared as a side effect, because restructuring two bullets with em-dashes broke the comma-list pattern the checker keys on. Still exactly 2 pages, zero overfull/underfull boxes, PDF re-inspected. Critique marked STALE - it scored the pre-edit document.
