# Note what is deliberately NOT here:
#
#   Package.resolved      tracked on purpose — see "Dependency lock" below
#   Fixtures/**/*.xcodeproj  tracked on purpose, so acceptance fixtures build
#                            without xcodegen installed
#
# Rule of thumb for anything added later: ignore what a build or a run produces,
# track what a build or a run needs.

# ── Dependency lock ───────────────────────────────────────────────────────────
# Package.resolved is intentionally NOT ignored. Do not add it.
#
# This package's product is an executable, so SwiftPM's convention is to commit
# the lock — but there is a sharper reason here. SwiftSyntax decides where a
# node's trivia ends, which decides the UTF-8 byte range a mutation is anchored
# to, which is an input to its Mutation ID. A floating dependency therefore means
# two machines can derive different IDs from identical source, and every promise
# this tool makes about reproducing a plan quietly stops holding. The pinned
# version is recorded in each plan's ToolchainFingerprint; the lock is what makes
# that recording mean something.

# ── MutantKit's own output ────────────────────────────────────────────────────
# Sandboxes, run locks, coverage/result caches, checkpoints, artifacts and
# rendered reports. Both names are ignored: `.mutantkit` is current and
# `.mutare` is the prior tool name kept for any mixed-version transition.
# (RunContextProbe.gitState also strips these from its digest independently,
# so the digest does not rely on a project having these rules — but ignoring
# them here keeps `git status` clean too.)

# Artifacts from the default output paths of `plan`, `shard`, `run` and `merge`,
# anchored to the repository root so a plan.json committed as a test fixture is
# not swallowed by the same rule.

# ── Reference clones ──────────────────────────────────────────────────────────
# Independent git repositories cloned for investigation. They are not part of the
# build, are not distributed, and cannot be committed here without vendoring
# someone else's history. Each keeps its own licence — see THIRD_PARTY_NOTICES
# section 4.
#
# To restore them in a fresh clone:
#   mkdir -p reference && cd reference
#   git clone https://github.com/muter-mutation-testing/muter.git
#   git clone https://github.com/ericodx/swift-mutation-testing.git
