# Prior Art and Provenance

Wiki Engine is repository-authored implementation work. Its author declares that public projects were studied for product patterns and that donor code, templates, branding, and assets were not intentionally copied. This is an authorship declaration, not independent forensic proof; exact observed revisions are retained in `provenance/BUILD-PROVENANCE.json`.

Point-in-time references observed on 2026-07-27:

- Andrej Karpathy, **The LLM Wiki** — raw/wiki/schema and ingest/query/lint concept. The observed gist did not provide a verified software license, so it is treated as attributed conceptual prior art only.
- `AgriciDaniel/claude-obsidian` — locking, conservative source preservation, Bases, and agent-oriented workflows. GitHub reported MIT.
- `green-dalii/obsidian-llm-wiki` — native Obsidian interaction, duplicate/conflict handling, graph retrieval, and lint. GitHub reported Apache-2.0.
- `kytmanov/obsidian-llm-wiki-local` — content hashes, rejection feedback, manual-edit protection, draft review, local/provider-flexible operation, and tests. GitHub reported MIT. Repository feature statements are not runtime witnesses for Wiki Engine.
- `johnfkoo951/cmds-llm-wiki` — broad Web Clipper and source-type routing ideas. GitHub returned no detected license during review; no code/templates were copied.
- `liyading1818/obsidian-llm-wiki` — transcript-to-source-to-wiki workflow. No detected license was relied upon; no code was copied.
- `kepano/clipper-templates` and official Obsidian Web Clipper documentation — deterministic variables, triggers, and import/export behavior. GitHub reported MIT for the template repository.
- `Astro-Han/karpathy-llm-wiki` at `eafcc77001e496cc43499e4923b663aec722c813` — compact installable skill and explicit arguments against several heavier controls. README-declared behavior only.
- `sdyckjq-lab/llm-wiki-skill` at `efa2294dd7c00479f7d8463fef88812d2fd5d1bc` — multi-platform skill, graph workbench, deduplication, confidence states, and broad extraction. README-declared behavior only.
- `ndjordjevic/pin-llm-wiki` at `e76e4012d8c393665517de6609a0197ede99a51d` — local citable Wiki, raw captures, URL acquisition, soft deletion, and Git review. README-declared behavior only.
- `bradautomates/claude-video` `/watch` skill — transcript-first and targeted timestamp frame concepts. The installed skill reported MIT. Wiki Engine ships no donor Watch code.
- Vault Y Content Engine — locally owned design lessons: immutable captures, provenance, user annotations, deduplication, and promotion gates. Wiki Engine deliberately excludes its broad service matrix and speculative 0–100 content scoring.
- Session Save System — locally owned architecture lessons: one kernel, thin agent adapters, exact identity, bounded reads, atomic writes, receipts, read-only Review, and evidence/authority separation.

Feature claims above are repository-declared unless explicitly described as a Wiki Engine test result.
