TH08: Imperishable Night semantic reconstruction

TH08 is the flagship sibling of the already-published TH04 case: historical Touhou reconstruction with semantic naming, Evidence notes, and agent session routes. We feature the **method**, not ripped modern Steam builds.

4/5 — Flagship historical reconstruction

Quality. Semantic reconstruction of Imperishable Night 1.00d with Evidence culture.

Evidence. Agent reading routes, evidence ledgers, guards — same family as th04.

Limits. REA not always named in README; still RE-adjacent Evidence practice.

For. Builders studying PC-98 / Touhou reconstruction loops.

What it is. A large MIT C++ reconstruction aiming at TH08 1.00d behavior with documentation for humans and agents.

Relation to REA. Same Evidence-first culture as other N0zoM1z0 showcases; pair agent notes with runnable reconstruction modules. REA may be one of several tools in the loop.

Workflow. Follow the project’s agent reading route → bounded Evidence batches → promote accepted facts into repo memory → falsify against tests.

Evaluation. High star signal and mature docs. Use beside /showcase/th04/ rather than duplicating empty shells.

Compliance

Historical game source reconstruction under MIT; not a DRM-strip guide for modern commercial releases.

Takeaways

Historical reconstructions teach Evidence loops.
Runnable code arbitrates agent prose.
Keep modern DRM/Steamless how-tos out of teaching pages.
