 ## 🔬 Latest Smoke Findings (2026-04-02)
+- [x] Ownership snapshot publishing now has a live-source maintainer path on `2026-04-11`: `scripts/build-latest-ownership-snapshot.sh` discovers the current supported `above1` IDX/KSEI PDF, imports it into an isolated temp DB, emits release-ready SQLite + manifest artifacts, and records the source IDX metadata in the manifest
+- [x] Verification on `2026-04-11`: `nix develop --command cargo test`, `bash -n scripts/build-latest-ownership-snapshot.sh`, and a real `nix develop --command scripts/build-latest-ownership-snapshot.sh --idx-bin ./target/debug/idx --output-dir tmp/ownership-snapshot-live` run all passed; the current live source produced `7214` rows for `955` tickers with `as_of_date=2026-03-31`
 - [x] Final release-hygiene pass on `2026-04-06`: crate metadata now declares `rust-version = 1.85`, README install docs now spell out Cargo helper-runtime expectations plus persistent `nix profile install`, and CI install smoke now runs the mock smoke matrix against the installed binary instead of only checking `idx version`
 - [x] Verification on `2026-04-06`: `nix develop --command cargo build`, `nix develop --command cargo clippy -- -D warnings`, `nix develop --command cargo test`, `nix develop --command cargo package --allow-dirty --locked`, and `scripts/live-smoke.sh --bin ./tmp/release-install/bin/idx --no-build --mode mock` all passed
 - [x] Publish review blocker batch on `2026-04-05`: the default Nix app/package path builds again without relying on an untracked runtime module, `ownership import --force` now re-imports the same release SHA atomically, and current ownership views (`ticker`, `entity`, `cross-holders`, `concentration`, `graph`) now scope KSEI data to the latest imported release instead of blending historical snapshots

+# Ownership Snapshot Publishing
+
+This document covers the maintainer workflow for producing and publishing the
+ownership snapshot artifacts consumed by `idx ownership sync`.
+
+## Goals
+
+- Build the snapshot from the currently discoverable supported IDX/KSEI source,
+  not from an ad hoc local DB.
+- Keep the published manifest URL stable for end users.
+- Record source provenance in the manifest so the published SQLite artifact can
+  be traced back to the live IDX announcement and PDF URL used to build it.
+
+## Recommended GitHub Releases Layout
+
+Use a dedicated stable release tag for snapshot assets:
+
+- tag: `ownership-snapshot-current`
+- manifest asset: `ownership-snapshot-manifest.json`
+- SQLite asset: `ownership-snapshot-YYYY-MM-DD.sqlite`
+
+Recommended public manifest URL:
+
+```text
+https://github.com/0xrsydn/idx-cli/releases/download/ownership-snapshot-current/ownership-snapshot-manifest.json
+```
+
+Avoid `.../releases/latest/download/...` if normal app releases and snapshot
+publishes share the same repository. The repo's "latest" release can drift away
+from the ownership snapshot release.
+
+## Manual Maintainer Flow
+
+Run the publisher helper inside `nix develop` so `mutool` and the
+`curl-impersonate` helper are available:
+
+```bash
+nix develop --command cargo build
+nix develop --command scripts/build-latest-ownership-snapshot.sh \
+  --idx-bin ./target/debug/idx \
+  --output-dir dist/ownership-snapshot \
+  --repo 0xrsydn/idx-cli \
+  --release-tag ownership-snapshot-current
+```
+
+The script performs these steps:
+
+1. `idx -o json ownership discover --family above1 --limit 1`
+2. verifies the discovered report is the current supported import path
+3. imports that PDF into an isolated temp ownership DB
+4. checks that the imported release metadata is non-empty and tied to the same
+   source URL
+5. runs `scripts/build-ownership-snapshot.sh` to emit the SQLite artifact and
+   base manifest
+6. enriches the manifest with `source` provenance metadata
+
+The resulting manifest records:
+
+- `source.family`
+- `source.listing_page_url`
+- `source.query_url`
+- `source.pdf_url`
+- `source.title`
+- `source.publish_date`
+- `source.original_filename`
+
+That metadata is additive. Existing sync clients can still parse the manifest.
+
+## Upload Step
+
+After the local build succeeds, upload these two files to the
+`ownership-snapshot-current` GitHub release:
+
+- `dist/ownership-snapshot/ownership-snapshot-manifest.json`
+- `dist/ownership-snapshot/ownership-snapshot-YYYY-MM-DD.sqlite`
+
+Only after this manual flow is reliable should the repo automate it in
+GitHub Actions.
+
+## GitHub Actions Workflow
+
+The repo now includes a manual workflow at
+`.github/workflows/publish-ownership-snapshot.yml`.
+
+Current behavior:
+
+- trigger: `workflow_dispatch` only
+- builds `idx` inside `nix develop`
+- runs `scripts/build-latest-ownership-snapshot.sh`
+- uploads the generated files as workflow artifacts
+- creates the stable release tag if needed
+- uploads the manifest and SQLite asset to that release with `--clobber`
+
+This is intentionally manual-first. Add a schedule only after a few successful
+publish runs confirm the live source remains stable enough.

 The command is intentionally manifest-driven so the repo can publish snapshots in GitHub releases, object storage, or a local filesystem path without changing the CLI.
