Signal Ledger compounds reading into knowledge base

Hot take: this is less a product than a disciplined operating system for research, and the real value is the editorial contract, not Claude itself.

• –Strong workflow design: the “contract before session 1” pattern is the clearest takeaway and is probably the most reusable part.
• –Good anti-hype mechanism: forcing corroboration and logging negative signal makes the ledger more evidence-driven than a normal note stack.
• –Practical limitation surfaced: a single append-only file becomes unwieldy past roughly 50K words, so compaction is a real engineering concern.
• –This will only work for people with active projects; without a live use case, it collapses back into summarization.
