A promoted Layer 0 source contains metric or planning evidence: "JetStream Web is slowly being rolled out to other teams, notably the baggage team . By collaborating with our RAIN devs and other designers , we hope to reduce design and dev hours with a proper design system."

A promoted Layer 0 source contains testimonial-like evidence: "Field feedback and rollout observations increasingly served as the primary inputs to design iteration. Examples captured in program communications included environmental interaction failures (rain/cold), device readiness variability (scanner update state), and operational cons..."

Launched internal design system, resolving 500+ component variations and reducing design-to-dev friction through governance, token-first architecture, and distributed platform ownership.

On Jan 27, 2026, Tre framed Ryan's growth to Jill specifically in terms of proactive field research: 'Ryan is going to go outside to go to the airport and get baselines for things we've been told we're going to improve.' This is Tre articulating Ryan's proactive ownership in the same conversation that Jill confirmed the coaching effect.

On Jan 6, 2026, Tre's director Liza named the read in a 1:1 with Tre: 'In meetings, he's a sponge. But he looks like he's waiting for the gun to go off.' This is the canonical before-state quote for the case study, captured verbatim in Tre's 1:1 notes.

In the same Jan 6, 2026 1:1, Tre relayed Jill Reed's observation to Liza and explicitly named Ryan's growth goal: be proactive, write down the questions you need answered, drive those conversations yourself rather than waiting for official kickoffs. Tre framed it as a single concrete target, not a development plan.

On Dec 17, 2025, Tre's PM partner Neeti named the before-state in a 1:1: 'I agree Ryan was just waiting to see things shift. He should be asking what next, what else — not waiting for what next, what else, and to be proactive.' This is verbatim before-state evidence, captured in Tre's notes.

Q1 2026 quarterly review (covering the November 2025 transfer through March 2026 arc) confirms: Ryan received explicit positive feedback on initiative, communication, and partnership-building (Jan 13) immediately after field visit coaching, and senior leadership identified Ryan for expanded leadership responsibility (Jan 6, Liza). The synthesis surface — quarterly, not in-the-moment — confirms the coaching arc.

By Feb 25, 2026, Tre's director Liza was actively defending Ryan's thoroughness against pace pressure from the PM, with the framing: 'Because he's so thorough, they think he's slow.' This is after-state evidence — Liza holding the line on Ryan's behalf without Tre asking her to.

On Feb 25, 2026, Tre actively partnered with Ryan's PM Neeti to defend Ryan's thoroughness against pace concerns: 'Ryan is doing his due diligence, going to fact-check and get information... I'm working with Neeti to do this. She wants it to happen faster, but it's thorough.' Tre owning the cross-functional advocacy.

On Jan 27, 2026, in a performance conversation, Jill Reed (Ryan's prior manager) confirmed Tre's coaching quality directly: 'Your direct team — they like you, you help them. They feel respected. They feel helped. They feel coached, supported.' Direct testimony from someone outside Tre's reporting chain.

On Jan 21, 2026, Ryan ran the SeaTac air cargo field visit himself — without Tre present — alongside the PM, the engineering lead, and the researcher, and presented field findings independently to the cross-functional team at the product-and-design peer review. Visit 2 of the progressive autonomy model.

Tre articulated and applied a progressive autonomy coaching model on his RAMP/Cargo team — model the behavior in a paired setting, give the direct report a framework for in-the-moment decision-making (a traffic-light escalation rule), then hand off ownership in a deliberate solo setting. Documented in his own contributions log on Jan 13, 2026.

On Jan 13, 2026, Tre positioned Ryan as IROPS coordinator — a cross-functional role coordinating three designers — to avoid duplication across the team and signal trust in Ryan's expanded capability. This was a positioning decision Tre made, not a title change requested through HR.

On Jan 6, 2026, immediately on the back of Tre's coaching conversation with Liza, Liza identified Ryan for expanded leadership responsibility. The recognition followed Tre's positioning, not the other way around.
