Use right before commit-changes on a memex working tree, after editing any Rust crate under crates/, or when reproducing a red CI run locally. Optionally runs the Postgres-gated integration suite when the memex-pg container is up and .env is sourced.

Verify the Memex Repo Before Committing

Run memex's three CI gates locally — cargo fmt --check, cargo clippy with warnings denied, and the workspace test suite — so a red CI is caught on your machine before you push. Optionally extend the run with the Postgres-gated integration suite. This complements, and does not replace, memex's own CI (.github/workflows/ci.yml); CI stays the authority.

When to Use

• Immediately before invoking commit-changes on a memex working tree.
• After editing any Rust source under crates/ (cli, sync, db, mcp, extract), Cargo.toml, or rust-toolchain.toml.
• When a memex CI run went red and you want to reproduce the failing gate locally with the same toolchain.
• Before opening a pull request against pjt222/memex.

Inputs

• Required: A checkout of the memex repo (a clone of github.com/pjt222/memex) with cwd set to the repo root. The gates read rust-toolchain.toml (pinned 1.96.0 + rustfmt/clippy components), so run from the root, not a subcrate.
• Required: A Rust toolchain on PATH (rustup provisions the pinned channel via rustup show). Confirm with command -v cargo.
• Optional (integration gate only): A running Postgres+pgvector on :5433 (the memex-pg container) and a sourced .env supplying MEMEX_TEST_PG_URL (and VOYAGE_API_KEY for embedding-backed tests).

Procedure

Step 1: Confirm the toolchain and working directory

The gates must run from the repo root so rust-toolchain.toml selects the pinned 1.96.0 toolchain — local and CI rustfmt/clippy then match.

# From the memex repo root
test -f rust-toolchain.toml || { echo "not at memex repo root"; exit 1; }
rustup show          # provisions/reports the pinned 1.96.0 toolchain
command -v cargo     # toolchain must be on PATH

Expected: rust-toolchain.toml exists, rustup show reports the active toolchain as 1.96.0, and cargo resolves to a path.

On failure: If you are not at the repo root, cd there first. If cargo is missing, add it to PATH (e.g. export PATH="$HOME/.cargo/bin:$PATH") and re-run.

Step 2: Gate 1 — format check

Mirrors the CI rustfmt job (cargo fmt --all --check). Read-only: it reports formatting drift without rewriting files.

cargo fmt --all --check

Expected: Exit 0 and no diff output — the tree is already formatted.

On failure: Non-zero exit prints the unformatted hunks. Apply the fix with cargo fmt --all, re-stage, and re-run this gate. Mark the overall verify FAIL until this gate is clean.

Step 3: Gate 2 — clippy with warnings denied

Mirrors the CI clippy step (cargo clippy --workspace --all-targets -- -D warnings). --all-targets lints tests and examples too; -D warnings makes any lint a hard error, matching CI exactly.

cargo clippy --workspace --all-targets -- -D warnings

Expected: Exit 0 with no warnings emitted.

On failure: Each warning is promoted to an error and listed with its lint name and source span. Fix the code (or, only when justified, add a scoped #[allow(...)]), then re-run. Mark the overall verify FAIL until clean.

Step 4: Gate 3 — workspace unit tests

Mirrors the CI unit-tests step (cargo test --workspace). This runs the non-ignored suite across every crate.

cargo test --workspace

Expected: Exit 0 and a test result: ok. line for each crate's test binary. The unit count is ~49 at v0.4.0 and grows per milestone (M5 adds watcher tests). Treat the count as informational only — assert on exit 0 / test result: ok, never on a specific number.

On failure: A non-zero exit and test result: FAILED. name the failing tests. Reproduce a single one with cargo test --workspace <test_name> -- --nocapture, fix, and re-run. Mark the overall verify FAIL.

Step 5: Gate 4 (optional) — Postgres-gated integration suite

The #[ignore]-gated integration suite is omitted from CI today (it needs a Postgres+pgvector service and a VOYAGE_API_KEY secret — see docs/CONTINUE_HERE.md §5). Run it locally only when the database and .env are available; skip this gate otherwise without failing verify.

# Only when the memex-pg container is up and .env is sourced:
docker start memex-pg            # idempotent if already running
set -a && . ./.env && set +a     # exports MEMEX_TEST_PG_URL, VOYAGE_API_KEY, ...
MEMEX_TEST_PG_URL="$MEMEX_TEST_PG_URL" cargo test --workspace -- --include-ignored

Expected: Exit 0 with test result: ok. including the integration binaries. The total is ~60 at v0.4.0 (unit + ~11 integration) and also grows per milestone — informational only.

On failure: If the suite fails because Postgres is unreachable or MEMEX_TEST_PG_URL is unset, that is an environment gap — note it as "integration gate skipped" rather than a code FAIL. If it fails with actual test result: FAILED., treat it as a real FAIL and fix.

Step 6: Report per-gate results and the overall verdict

Summarize each gate (PASS/SKIP/FAIL) and the rolled-up verdict.

# Conceptual rollup: overall is non-zero if ANY required gate failed.
echo "fmt: <PASS|FAIL>  clippy: <PASS|FAIL>  unit-tests: <PASS|FAIL>  integration: <PASS|SKIP|FAIL>"

Expected: Gates 1–3 (required) all PASS. The integration gate is PASS or SKIP. Overall verdict PASS.

On failure: Exit non-zero overall if ANY required gate (1–3) or a non-skipped integration run failed. Do not proceed to commit-changes until the verdict is PASS.

Validation

• Run from the memex repo root (rust-toolchain.toml present; rustup show reports 1.96.0)
• cargo fmt --all --check exits 0 with no diff
• cargo clippy --workspace --all-targets -- -D warnings exits 0
• cargo test --workspace exits 0 with test result: ok. per crate
• Test counts reported as informational (~49 unit / ~60 total at v0.4.0), never asserted as a pass/fail threshold
• Integration gate either run (Postgres up + .env sourced) and green, or explicitly recorded as SKIPPED
• Overall verdict is non-zero if any required gate failed

Common Pitfalls

• Asserting a fixed test count. Counts grow each milestone; a literal assert 49 turns a healthy run red. Assert exit 0 / test result: ok and report the count as ~N at v0.4.0.
• Running from a subcrate. Outside the repo root, rust-toolchain.toml is not picked up, so local fmt/clippy can drift from CI's 1.96.0 and give false greens or reds. Always run from the root.
• Treating a skipped integration gate as a failure. No Postgres / no .env means SKIP, not FAIL. Only test result: FAILED. on a run that actually executed is a real failure.
• Dropping --all-targets from clippy. Without it, lints in test and example code are missed, so local clippy passes while CI fails. Match CI's --workspace --all-targets -- -D warnings exactly.
• Treating this as a CI replacement. This is a local early-warning gate. The authority remains .github/workflows/ci.yml; a green local run does not exempt a PR from CI.
• Forgetting to source .env before the integration gate. A .env-loading gotcha is documented in docs/OBSERVATIONS.md; export the file (set -a && . ./.env && set +a) so MEMEX_TEST_PG_URL reaches the test process.
