Type: knowledge

Append-only history. `decisions.md` indexes dated decision volumes.
Dated `YYYY-MM-DD-topic.md` files are session writeups — the real ledger
bodies. `DEVLOG.md` declares `Generated: tools/ledger_index.sh` and is a
replaceable reverse-chronological projection; do not hand-edit it. Never
rewrite session logs after the fact; the formal record of *current design*
lives in `Type: law` and `Type: spec` pages, not here.

Append new decisions only to the current dated volume under `decisions/`;
older volumes stay closed. A deliberate corpus migration may add or repair
structural role metadata such as `Type:` without rewriting historical prose,
as defined by `wiki/process/meta.md`.
