P0 Badge Preserve verify-bindings JSON shape

For existing automation that runs clawhip config verify-bindings --json and deserializes the previous machine-readable BindingAudit shape, this replaces the top-level verdicts object with channel_audit/drift_audit, so consumers break even when all bindings are healthy. The repo guidance treats breaking CLI interface changes as P0; keep the existing top-level fields and add drift data compatibly or version the output.

P1 Badge Exclude manual git monitors from setup drift

When a pre-existing config has a manually managed [[monitors.git.repos]] with name or github_repo but no setup-owned route, monitor_repo_identity makes monitor.repo non-empty and this loop reports repo_identity_mismatch; run_verify_bindings then exits 1. That breaks clawhip config verify-bindings for normal configs that only use git monitors to send events, so only monitors known to be setup-owned should participate in this drift check.

P2 Badge Accept nameless setup monitors on reruns

When Discord returns a channel without a name (or the optional channel_name hint is removed), setup writes both the route and monitor with channel_name = None; on the next identical setup --bind, the monitor is selected by path/name/github_repo but this helper only accepts setup ownership when a name is present, so the command errors with existing monitor is not setup-owned instead of being idempotent.

Clippy repair for PR #284 is complete and pushed in b0f666a.

Verification run in this worktree:

  • cargo fmt
  • cargo clippy -- -D warnings
  • cargo test
  • cargo build

Scope stayed limited to CI clippy cleanup: FindingParams now carries the finding arguments, the repo-filter check uses contains_key("repo"), and the collapsible if warnings in config.rs/main.rs are resolved.

P0 Badge Preserve existing setup --bind usage

Existing automation can run clawhip setup --bind owner/repo=CHANNEL just to create/update the Discord route; this new fallback now errors unless a checkout can be inferred or --bind-checkout is added, so the old CLI invocation fails from outside that repo and for any multi-bind command before Discord is even checked. The repo review guidance treats breaking CLI interface changes as P0, so the checkout monitor onboarding needs to be optional/backward-compatible for existing --bind callers.

P1 Badge Do not steal monitors by basename

When binding owner2/repo while a setup-owned monitor for owner1/repo already exists, this basename match (name == "repo") selects the old monitor even though its github_repo is different; if the channel name matches, is_setup_owned_git_monitor accepts it and the update below overwrites that monitor's path/github_repo/channel, leaving the original route without its monitor. Owner-qualified repos should not fall back to name matches against monitors that already have a different github_repo.

P1 Badge Restrict manual route conflicts to wildcard routes

A valid manual override such as a branch-specific Discord route with filter = { repo = "owner/repo", branch = "main" } is not a duplicate setup route, but this audit flags any route that merely contains a repo filter whenever a setup route exists for that repo. Since run_verify_bindings exits nonzero on any drift finding, configs that add more-specific repo routes now fail verification; this check should mirror the exact wildcard conflict tested in apply_repo_channel_binding rather than all repo-filtered routes.

REQUEST_CHANGES

Blocking issues remain in the current head b0f666a:

  • P0: existing clawhip setup --bind owner/repo=CHANNEL usage is no longer backward-compatible. From a directory where the checkout cannot be inferred, the command exits before Discord lookup with bind owner/repo: checkout path could not be resolved; pass --bind-checkout owner/repo=PATH. The new monitor onboarding needs to be optional or otherwise preserve the old route-only bind contract.
  • P0: clawhip config verify-bindings --json changed the top-level machine-readable schema from BindingAudit (verdicts) to {channel_audit, drift_audit}. Existing automation deserializing the documented/previous shape breaks even for healthy configs. Add drift compatibly while keeping the existing top-level fields or version the output.
  • P1: drift audit still treats ordinary manual git monitors with name/github_repo and no setup-owned route as repo_identity_mismatch, causing verify-bindings to fail normal monitor-only configs. Only setup-owned monitor records should participate in setup route/monitor drift.
  • P1: apply_repo_channel_binding matches monitors by basename (name == repo) even when an owner-qualified monitor already has a different github_repo, so binding owner2/repo can steal and rewrite owner1/repo's monitor.
  • P1: drift audit flags any route containing a repo filter as manual_route_conflict, including valid branch-specific/manual override routes with additional filters. Restrict the conflict check to the exact wildcard duplicate shape.

Verification run locally in /mnt/offloading/Workspace/clawhip-pr-284-review-r1: cargo fmt --check && cargo clippy -- -D warnings && cargo test && cargo build passed. I also reproduced the setup bind compatibility failure and the changed verify-bindings JSON keys locally.

REQUEST_CHANGES

Blocker: config verify-bindings now reports route/monitor drift for ordinary manual git monitors that have no setup-owned route, because audit_route_monitor_drift treats every monitors.git.repos[*].name as a repo identity (src/binding_verify.rs:540-554) and then emits repo_identity_mismatch whenever there is no setup route (src/binding_verify.rs:396-414). That makes the new drift check broader than issue #282's setup-owned route/monitor onboarding scope and breaks existing/manual monitor configs.

Repro from this worktree:

cat >/tmp/clawhip-manual-git-monitor-no-channel-284-r1.toml <<'EOF'
[[monitors.git.repos]]
path = "/tmp"
name = "manual"
EOF
cargo run --quiet -- config verify-bindings --config /tmp/clawhip-manual-git-monitor-no-channel-284-r1.toml --json

Observed: exit 1 with drift_audit.findings[0].code == "repo_identity_mismatch" and message git monitor repo 'manual' has no matching setup-owned route, even though this is a standalone manual git monitor and has no route/channel binding to drift.

Required fix: restrict route/monitor drift diagnostics and hard failures to setup-owned bindings/conflicts, or add an explicit backward-compatible ownership marker so manual git monitors are not classified as setup-owned merely because they have name/github_repo metadata. Add a regression test for a manual [[monitors.git.repos]] without a setup route staying drift-clean.

FIX_PUSHED: pushed e4e92d1 to clawhip-issue-282-route-monitor-idempotency for PR #284.

Fix summary:

  • Restricted route/monitor drift ownership so git monitors only participate as setup-owned when they have setup binding metadata (channel and channel_name), preventing ordinary manual monitors with only name/github_repo metadata from producing repo_identity_mismatch.
  • Added regression coverage for a manual standalone [[monitors.git.repos]] with path = "/tmp" and name = "manual" staying drift-clean.
  • Kept related PR Fix route monitor onboarding idempotency #284 compatibility fixes in this branch: legacy setup --bind can remain route-only when no checkout can be resolved, JSON verify output keeps top-level verdicts, setup binding updates avoid stealing a different owner-qualified monitor, and manual route conflicts are limited to exact wildcard duplicate shape.

Verification evidence from /mnt/offloading/Workspace/clawhip-issue-282-route-monitor-idempotency:

  • cargo fmt --check passed.
  • cargo check passed.
  • cargo test binding_verify -- --nocapture passed: 24 passed.
  • cargo test repo_channel_binding -- --nocapture passed: 5 passed.
  • cargo test passed: 643 passed.
  • cargo clippy -- -D warnings passed.
  • Blocker repro now exits 0 and returns {"drift_audit":{"findings":[],"ok":true},"verdicts":[]} for /tmp/clawhip-manual-git-monitor-no-channel-284-r1.toml.

FIX_PUSHED: pushed the missing legacy setup bind integration regression on top of the PR branch.

Added tests/setup_bind_legacy_route_only.rs, covering clawhip setup --bind owner/repo=CHANNEL from a directory without an inferable checkout. The test uses a local mock Discord channel lookup and verifies the command writes a route-only binding while not creating [[monitors.git.repos]].

Verification run:

  • cargo fmt --check
  • cargo test legacy_setup_bind_without_checkout_writes_route_only -- --nocapture

P0 Badge Do not fail route-only bindings

For configs created by legacy or current setup --bind owner/repo=123 without --bind-checkout, setup intentionally writes only the Discord route, but this unconditional missing_git_monitor finding marks that valid route as drift. Because run_verify_bindings exits nonzero whenever drift_audit.ok is false, clawhip config verify-bindings and setup --bind --verify-bindings now fail for existing route-only bindings even when the Discord channel itself verifies successfully, which is a breaking CLI behavior change under the repo review guidelines.

P2 Badge Normalize channel-name hints before drift comparison

When a setup route and its git monitor use equivalent hints that differ only by # or case, such as route channel_name = "dev" and monitor channel_name = "#DEV", this exact Option<String> comparison emits channel_name_mismatch even though the rest of the binding code treats those names as matching. That makes config verify-bindings exit 1 for a non-drifted setup-owned monitor; compare with the same normalized, case-insensitive semantics used for Discord name verification.

REQUEST_CHANGES

I verified the requested fixes on head df4a92377e97d9ecd09fc5c4951ba625b9d3fb7f and two prior blockers are still reproducible.

Blocking findings:

  1. Ordinary manual git monitors are still treated as setup-owned drift candidates.

Repro config:

[providers.discord]
bot_token = "test-token"

[[monitors.git.repos]]
path = "/manual/repo"
name = "repo"
github_repo = "owner/repo"
channel = "123"
channel_name = "dev"

Command:

target/debug/clawhip --config /tmp/clawhip.toml config verify-bindings --json

Observed: exits 1 and emits drift_audit.findings[0].code == "repo_identity_mismatch" for the manual monitor. That violates the requested fix: drift audit must be restricted to setup-owned monitor metadata, not ordinary manual git monitors that happen to have github_repo, channel, and channel_name.

Required fix: add/persist an explicit setup-owned marker or otherwise use a non-ambiguous ownership signal, and have drift audit ignore all manual git monitors unless that setup ownership marker is present.

  1. Binding can still steal a basename-matching monitor for a different owner-qualified repo.

Repro starting config:

[providers.discord]
bot_token = "test-token"

[[monitors.git.repos]]
path = "/old/repo"
name = "repo"
github_repo = "owner1/repo"
channel = "old"
channel_name = "dev"

Command with a mocked Discord /channels/123 -> {"name":"dev"} and a checkout path containing .git:

target/debug/clawhip --config /tmp/clawhip.toml setup \
  --bind owner2/repo=123 \
  --bind-checkout owner2/repo=/tmp/repo2

Observed saved config rewrites the existing monitor from github_repo = "owner1/repo" to github_repo = "owner2/repo" because apply_repo_channel_binding matches monitor.name == "repo" even when the monitor already has a conflicting owner-qualified github_repo.

Required fix: when the requested repo is owner-qualified, never match/reuse an existing monitor by basename if that monitor has a different non-empty github_repo; treat it as non-matching or a hard conflict without mutating it.

Verification run locally:

  • cargo fmt --check passed
  • cargo test passed (648 tests)
  • cargo clippy -- -D warnings passed
  • cargo build passed
  • Targeted legacy route-only test passed: cargo test --test setup_bind_legacy_route_only legacy_setup_bind_without_checkout_writes_route_only
  • Targeted JSON compatibility test passed: cargo test verify_bindings_json_preserves_top_level_verdicts
  • JSON smoke confirmed top-level keys include verdicts and drift_audit
  • GitHub CI for latest head showed CI Format/Check/Test/Clippy/Build successful; Release-only jobs were skipped as expected

Terminal verdict: REQUEST_CHANGES

P2 Badge Preserve symlinked config files when saving

When the configured path is a symlink (common for dotfiles-managed configs), this rename replaces the symlink itself with the temp file instead of writing through to the symlink target. The previous fs::write(path, ...) followed the symlink, so setup/the config editor can now silently detach the active config from the real dotfiles file; resolve the symlink target or avoid the rename path for symlinks.

P1 Badge Require repo identity before basename monitor matches

Fresh evidence beyond the earlier basename case: this branch still lets a setup-owned monitor match solely by name when the new bind is shorthand (repo) or the existing monitor has no github_repo. In those cases apply_repo_channel_binding rewrites that existing monitor for the new binding while the old setup route remains; the setup drift check only aborts for the newly bound repo, so the original route can be saved without its monitor.

MERGE_READY

Reviewed head 53eae02. The explicit setup_owned marker prevents manual git monitors with github_repo/channel/channel_name metadata from being treated as setup-owned drift candidates, owner-qualified binding no longer steals a basename-matching monitor from another owner/repo, legacy route-only bind remains covered, and verify-bindings JSON keeps top-level verdicts compatibility. CI is green and prior local full verification was reported green.
