docs/provenance.md: table of every component Igneum uses (origin, licence, what changed, why, how measured), what is new, what to adopt from upstream, own-code licence pending the project lead's decision. Licences verified on disk: rusty-kaspa ISC, chiavdf Apache-2.0, igneum-pow MIT, blake2b_simd MIT, blake3 CC0 or Apache-2.0, sha2 MIT or Apache-2.0, secp256k1 CC0, keccak Apache-2.0 or MIT. RandomX, SP1, revm, blst, ProgPoW, LWMA, Monero, GMP, sha3: approximate, not cloned.
site: litepaper gains the Built on the shoulders section and nav entry; index gains the two-line mention and footer link near the RandomX comparison; the block rate reads one block a second at launch, rising, where it read as permanent (litepaper diagram, index live section).
tools/upstream: README with the exact merge commands, expected conflict files from fork-divergence, the test list and the consensus-review rule; sync-upstream.sh fetches and opens the merge on a branch without committing. Not run against the fork.
docs/commercial/prover-customer-brief.md: one-page brief for a first proving customer at testnet, timeline from journey.json, risks, 10 candidates labelled approximate.
