Evidence

Project Type

Greenfield. No prior workspace content; the repo is a freshly initialized git repo with no commits.

Sources Scanned

• aidlc/spaces/default/memory/org.md — framework defaults for the five practice areas (way of working, walking skeleton, testing posture, deployment, code style).
• Initial project description: "wedding newspaper generator — author content as markdown, render as a printable newspaper in pure HTML5+CSS, print to A4 from the browser. Fully local, never deployed beyond localhost."
• Primary-source web research (whatwg fetch spec, MDN same-origin policy, CORS handbook) on whether a file:// page can read sibling local files.
• Empirical browser test (2026-09-13): real Chromium driven via node
  • playwright-core. Plain Chromium: fetch('article.txt') from a file:// page → blocked (TypeError: Failed to fetch, CORS from origin 'null'); native file picker → works. Chromium with --allow-file-access-from-files: fetch works but requires a non-default, security-weakening launch flag.

Participant Evidence

• Lead draft: team-practices.md, discovered-rules.md, evidence.md, practices-discovery-timestamp.md.
• Support contributions (contributed into the artifacts):
  • contributions/aidlc-quality-agent.md — test-after posture justified; renders/print as the testable surfaces; keep A4 containment + markdown fidelity as the acceptance checks.
  • contributions/aidlc-developer-agent.md — content/presentation separation (content/ vs templates/), tolerant transform, plain-HTML file layout.
  • contributions/aidlc-devsecops-agent.md — zero-dependency = zero supply-chain risk; no-remote-URLs as a load-bearing security rule; the page must work offline.

Interview Decisions

• Q1 Way of working: C direct to main (solo local project).
• Q2 Walking skeleton: B no separate skeleton step.
• Q3 Testing posture: C unit tests for the markdown→HTML transform.
• Q4 Deployment/run: X resolved via research + confirmation — file-only static Python generator emitting a self-contained newspaper.html, with an in-page file-picker live-load path; no server, never beyond localhost.
• Q5 Code style: C no style rules, minimal and pragmatic.
• Q6 Content/presentation: A separate content/ and templates/.

Unresolved Uncertainty

• None blocking. The browser file:// constraint is settled empirically: use user-granted file access (picker/drag-drop), never fetch() of local files, except under the non-default Chromium flag.
