- Lints: `cargo clippy --workspace --all-targets -- -D warnings` must pass before commit.
- Lints: `cargo clippy --workspace --all-targets -- -D warnings` must pass in crates you touch before commit. Pre-existing debt in other crates is documented in `PROTOCOL-AUDIT.md`.
- Tests live next to code under `#[cfg(test)]` modules, or in `crates/<x>/tests/`.
- Wire format types: `crates/wzp-proto/src/packet.rs` is authoritative. Do not duplicate field semantics elsewhere.
- Commit one task per commit. Reference task ID in commit message: `T1.1: widen MediaHeader to v2`.

## T1.5.1 — Remove `unwrap()` from `encode_compact`
- **Parent:** T1.5 (Approved)
- **PRD:** `PRD-wire-format-v2.md` (cleanup)
- **Effort:** 20 min
- **Files:**
- `crates/wzp-proto/src/packet.rs`
### Context
`encode_compact` calls `ctx.last_header().unwrap()` at line ~262. The invariant ("a full header is forced on the first frame and every `MINI_FRAME_FULL_INTERVAL` frames") makes it logically safe, but standard #4 forbids `unwrap()` in production paths. Carried over from v1.
### Steps
1. Open `crates/wzp-proto/src/packet.rs`. Find `pub fn encode_compact`.
2. Replace the `unwrap()` with one of:
- **Recommended:** when `ctx.last_header()` is `None`, fall back to emitting a full frame and force `frames_since_full = 0`. This makes the invariant explicit in the code rather than implicit.
- Alternative: return `Result<Bytes, EncodeError>` with a typed `NoBaselineHeader` variant. More invasive (changes the public signature).
3. Add a test that constructs a fresh `MiniFrameContext` and calls `encode_compact` immediately — without the existing fix, this would panic; with the fix, it should emit a full frame.
### Verify
```bash
cargo test -p wzp-proto encode_compact
cargo clippy -p wzp-proto --all-targets -- -D warnings
grep -n "\.unwrap()" crates/wzp-proto/src/packet.rs | grep -v "#\[cfg(test)\]\|^[[:space:]]*//\|tests::"
# the unwrap on line ~262 should be gone; only test-code unwraps remain.
```
### Done when
- No `unwrap()` in `encode_compact` or anywhere else in non-test code in `packet.rs`.
- New test passes; existing `encode_compact` tests still pass.

## T1.5.2 — Workspace clippy hygiene + document pre-existing debt
- **Parent:** T1.5 (Approved)
- **PRD:** `PRD-wire-format-v2.md` (process)
- **Effort:** 30 min
- **Files:**
- `docs/PROTOCOL-AUDIT.md` (add a "Known pre-existing clippy debt" section)
- This file (TASKS.md) — update report template instruction to require workspace clippy
### Context
T1.5 review revealed two issues: (1) the agent ran only `-p wzp-proto` clippy, not workspace; (2) workspace clippy fails with 9 `wzp-codec` errors and 3 `warzone-protocol` errors. Both are pre-existing (verified against HEAD~1). Need to capture these as known debt so they don't stay invisible, and tighten the report template to require workspace clippy on every task.
### Steps
1. Run `cargo clippy --workspace --all-targets -- -D warnings 2>&1 | grep -E "^error\[|could not compile" | head -50` and capture the output.
2. Add a section to `docs/PROTOCOL-AUDIT.md` named **"Known pre-existing clippy debt (as of T1.5.2)"** listing the failing crates and a brief description per error category (manual ASCII case-cmp, manual arithmetic check, loop index, etc.). Reference the commit SHA of HEAD at time of measurement.
3. In `docs/PRD/TASKS.md`, update the report template's "Test summary" section: change `cargo clippy --workspace --all-targets -- -D warnings: pass / fail` to `cargo clippy --workspace --all-targets -- -D warnings: pass / fail (or N known-debt errors in <crate>; see PROTOCOL-AUDIT.md)`. This makes the expectation explicit and gives agents a way to acknowledge known debt without re-discussing it every task.
4. Optional: add a `make clippy-baseline` or similar script to `tools/` that prints expected-error count so agents can detect regressions.
### Verify
```bash
grep -c "Known pre-existing clippy debt" docs/PROTOCOL-AUDIT.md # >= 1
grep -c "or N known-debt errors" docs/PRD/TASKS.md # >= 1
```
### Done when
- PROTOCOL-AUDIT.md has the known-debt section with current error counts and categories.
- TASKS.md report template reflects the new expectation.
- A follow-up cleanup task is created in the audit (separate from this one) to actually fix the pre-existing debt over time.
