The Agentic SDLC Playbook, out loud
Two speakers work through why the bottleneck moved, why vendor neutrality became a control requirement rather than a preference, and what it means to put the decision to allow or block into deterministic code instead of a review meeting.
It covers roughly what §1 to §4 of the playbook cover. It does not cover the stage plays, the autonomy matrix or the Substitution Test in any depth — for those, the playbook is the thing.
It is published as a way into the material, not as commentary on it. Where the audio and the playbook differ, the playbook is correct — it is the source, it is version-controlled, and it carries the citations. The same objection this repository records against recording a simulated terminal in CHG-2026-014908 applies to its own materials: a synthetic conversation presented as authority is the artefact that reads as evidence while being a performance. So it is labelled.
Two practical notes
Nothing downloads until you press play. The player requests metadata only, so landing here costs a few kilobytes rather than thirteen megabytes.
Playback stops if you navigate. This is a static multi-page site, not an application — following a link to another page reloads it and the audio ends. Open the playbook in a second tab if you want to read along, or keep this tab playing and browse in another.
Prefer to read, watch, or run it?

| Watch it run | Sixteen seconds of the control layer, recorded as it ran |
| One change, end to end | A single change followed through every stage |
