- Marker schema v3: each `[[attachments]]` entry carries `scope = "user" | "project"`. Pre-v0.21 markers without the field default to `Scope::User` silently. New error variant `Error::ScopeUnsupported { client, scope, supported }` fires when a caller asks for a scope the adapter doesn't advertise.
- **primitives (v0.21 — `kei-store` real S3 backend):**
- `S3CloudStore` — functional S3 / R2 / MinIO / Wasabi backend via `aws-sdk-s3` v1. GetObject / PutObject / ListObjectsV2 (paginated) / DeleteObject wired behind the existing `MemoryStore` trait (sync-over-async via a single-thread tokio runtime). Enables `keisei attach s3://my-bucket/brain/` as a real cloud-mount path, not just a local stub.
- Opt-in feature flag `s3` on the `kei-store` crate — off by default so users who don't need cloud pay zero binary weight. Enabling adds tokio + hyper + rustls + aws-sdk-s3 (~5 MB release binary growth).
- Opt-in feature flag `s3` on the `kei-store` crate — off by default so users who don't need cloud pay zero binary weight. Enabling adds tokio + hyper + rustls + aws-sdk-s3 (~5 MB release binary growth [estimate, E5 — not yet measured; would require `cargo build --release` before/after feature flag]).
- AWS default credential chain honoured (env vars → `~/.aws/credentials` → IMDS). No new credential format; RULE 0.8 secrets-single-source unchanged.
- Endpoint override for non-AWS S3-compat providers via `KEI_STORE_S3_ENDPOINT` env var (runtime) or `s3.endpoint` in `store-config.toml` (persistent). Path-style addressing auto-enabled when a custom endpoint is set (MinIO / some R2 configs).
- "Branch" semantics: S3 has no native branching, so a branch is modelled as a key prefix (`<branch>/<path>`). `branch()` sets the active prefix in-memory; default `main`.

### Fixed
- Placeholder: hook-bypass edge case follow-up to v0.15.1.
- **primitives/kei-store (v0.21.1 audit wave, HIGH-1):** `S3CloudStore::commit()` now calls a new `list_recursive(prefix)` helper (ListObjectsV2 without `delimiter`) so every nested key under the branch — e.g. `write("traces/x.jsonl", ...)` — contributes to the manifest hash. The previous implementation called `list("")` which under the hood used `delimiter="/"` and hid all sub-directory writes from the commit, silently breaking hash-stability. `commit()` ALSO strips any existing `manifest-*.json` entries from the input so the hash is stable across repeated commits on unchanged data.
- **primitives/kei-store (v0.21.1 audit wave, HIGH-2):** `S3Cfg::access_key_env` + `S3Cfg::secret_key_env` are now wired through to the aws-sdk-s3 builder. When both are set, we resolve the named env vars into an explicit `Credentials` provider and overlay it on the SDK config. Partial configuration (only one of the two set) now returns an error rather than silently ignoring it. Previously both fields were dead — configured users were getting the ambient AWS default chain instead of the named pair.
- **primitives/kei-store (v0.21.1 audit wave, HIGH-5):** all tests that mutate process env on `KEI_STORE_*` vars now take a shared `test_env::ENV_LOCK` mutex (exposed under `cfg(any(test, feature = "s3"))`). Prevents cargo-test parallelism from racing multiple tests on the same env state. `github.rs` dedups onto the shared lock; `s3_cloud/tests.rs` + `tests/s3_smoke.rs` now use it.
- **primitives/keisei (v0.21.1 audit wave, HIGH-3):** `detach.rs` + `mount.rs` now scrub every manifest-sourced string (brain name, brain path, config path, client type, error reason) through `display::sanitize_display` before `println!` / `eprintln!`. `status.rs` + `attach.rs` were already compliant; this closes the L9 regression gap for the other two print sites. Two new integration tests (`detach_sanitizes_control_chars_in_marker_fields`, `mount_sanitizes_control_chars_in_error_reason`) assert source-level guard presence.
- **primitives/keisei (v0.21.1 audit wave, HIGH-4):** extracted `adapters/jsonmcp.rs` (~107 LOC) as the shared JSON merge/remove/persist helper used by the `claude-code`, `cursor`, and `zed` adapters. All three adapters drop from ~170 LOC to ~105 LOC each and share a uniform error-surfacing contract (`Error::ConfigParseError { path }` rather than raw serde_json on parse failure). `continue_adapter.rs` is YAML-based and is unaffected.
- **security (v0.21.1 audit wave, H1):** `scripts/install-actionlint.sh` now verifies SHA-256 of the downloaded tarball before extraction. Per (OS, ARCH) hashes are pinned at the top of the script and documented as the output of `checksums.txt` on the upstream release page. If a hash is marked `SKIP` (documented as `[UNVERIFIED]` pending live fetch), the installer prints a WARNING. Missing `shasum` / `sha256sum` is a hard exit 2 — refuses to install an unverified binary. Env override `ACTIONLINT_SHA256_OVERRIDE=<hex>` lets CI inject the hash at runtime.
- **security (v0.21.1 audit wave, H2):** `kei-store::s3_cloud::client::validate_endpoint` rejects loopback / link-local / metadata hosts (`127.0.0.0/8`, `::1`, `169.254.0.0/16`, `fe80::/10`, `metadata.google.internal`, etc.) and plain-HTTP URLs by default. Closes the SSRF / IMDS-leak surface where an attacker-controlled `KEI_STORE_S3_ENDPOINT` pointed at `http://169.254.169.254` would cause the AWS default credential chain to sign requests against the instance metadata endpoint and leak IMDS creds. Env overrides: `KEI_STORE_S3_ALLOW_INTERNAL=1` (local MinIO / tests), `KEI_STORE_S3_ALLOW_INSECURE=1` (plain-HTTP). When a custom endpoint is set, explicit `access_key_env` + `secret_key_env` are REQUIRED — the default credential chain is no longer consulted for non-AWS endpoints.
- **docs (v0.21.1 audit wave, D1):** `docs/USB-BRAIN-GUIDE.md` now warns that **exFAT / FAT32 are NOT safe for multi-client attach** — SQLite WAL shared-memory mmap doesn't work reliably on those filesystems. Recommends APFS / ext4 / NTFS for `keisei mount`. Troubleshooting entry "SQLite corruption on mount-attach" added with recovery steps.
- **docs (v0.21.1 audit wave, D2):** the "~5 MB release binary growth" claim for the `s3` feature is now labelled `[estimate, E5 — not yet measured]` in both CHANGELOG.md and the `s3_cloud` module doc-comment. Prevents over-claim until a real `cargo build --release` before/after comparison is landed.
- **scripts (v0.21.1 audit wave, D3):** `scripts/validate-workflow-shas.sh` now exits 2 when UNVERIFIED pins exist AND no `GITHUB_TOKEN` was provided (rate-limit path). Previously silently returned 0 which masked incomplete verification in CI.
- **primitives/keisei (v0.19 audit hardening):** close 3 Security HIGH + 3 Critic HIGH + 2 Critic MEDIUM findings. Path-escape guard on `mcp_server` + `memory/artifacts/manifests` (absolute / `..` / canonical-mismatch → `PathEscape`); brain-name regex `^[a-z][a-z0-9_-]{0,63}$` (`InvalidName`); symlink-rooted brain inputs rejected (`BrainIsSymlink` — closes USB → `$HOME` pivot); MCP-entry collision check across all 4 adapters (`NameConflict` instead of silent clobber); dropped unused `rusqlite` dep (no C toolchain tail); `BrainPaths.{memory,artifacts,manifests}` relaxed to `Option<String>`; `$KEISEI_HOME`/`$HOME` resolver deduped into `paths.rs` SSoT; `fsx::write_atomic` rewritten on `tempfile::NamedTempFile` for Windows + cross-fs correctness; 5 adversarial integration tests added (16 total pass).
- **primitives/keisei (v0.19.2 polish):** dropped unused `ClientAdapter` imports from `mount.rs` + `detach.rs`; `Error::NotAttached` and `AttachRecord::has_client` now carry explicit `#[allow(dead_code)]` markers documenting that they're reserved for future callers / test-only respectively. `cargo check -p keisei` is warning-clean; integration suite is 19/19 pass (3 new: `marker_file_has_0600_perms_on_unix`, `status_sanitizes_control_chars_in_brain_name`, `manifest_too_large_rejected`). `brain.rs` module-level doc-comment now lists the v0.19 invariants (path confinement / symlink reject / name regex / manifest size cap) and flags schema v2 as v0.20.

### "NameConflict" on attach
- Another MCP server with the same name already exists in the client's config. Either rename your brain (`name` in manifest.toml) or remove the existing entry manually.
### SQLite corruption on mount-attach
- `kei-memory` / `kei-artifact` / `kei-social-store` databases show "disk image is malformed" or "database is locked" errors after a `keisei mount` on a USB drive.
- Root cause: the brain lives on **exFAT or FAT32**, which do not reliably support SQLite WAL-mode shared-memory mmap. Multi-client attach corrupts the DB.
- Fix:
1. Copy the brain dir to an **APFS** (macOS) / **ext4** (Linux) volume, either internal disk or a reformatted USB.
2. Re-attach via `keisei attach <new-path>` or `keisei mount <new-path>`.
3. For single-client use on the same exFAT drive, restrict to `keisei attach --scope=user` only — do NOT use `keisei mount`.
- Prevention: re-read step 0 → Prerequisites → "⚠️ WARNING" above.
