AntiPattern

Merge-Time Constraint Drift

integration-precondition-drift

Branch merge and automation fail because hidden preconditions—git checkout/ref assumptions, hook validations, publish/link state, and FSM transition legality—diverge across environments, producing noisy conflicts or hard rejections instead of the intended integration behavior.

MATCHESSolution

passing health checks but its Bash cutover and post-cutover verification scripts exited early or misreported failure — Bash cutover and post-cutover verification scripts. Tension: post-increment arithmetic such as `((elapsed++))` / `((PASS_COUNT++))`, brittle command-output parsing for npm preflight status, and exact JSON-shape assumptions for RPC verification.

MATCHESSolution

Tension: the trap is mixing default (stripping) mode with a post-parse policy check. Outcome: parse AFTER the guard.

MATCHESSolution

produces both files atomically — Faster way to ship a migration. Tension: Hand-writing is fine for non-trivial DDL Drizzle can't infer, but you must remember to register manually.

MATCHESSolution

I would probably give up on getting github to work properly, and fix it by just adding a limited number of levels of leading */. — In quick testing, this works to do what you want:. Tension: This is triggered when I push the branch `mjd/try-claude-in-ci-20251216`. Outcome: branches: ["*/ci-*", "*/*/ci-*", "*/*/*/ci-*"].

MATCHESSolution

If you use `git log ${{ github.event.pull_request.head.sha }} -1` instead of using environment variables. Tension: it would break given that it operates on the merge commit. Outcome: But remember that you need to set `fetch-depth`, for example to `0`. Otherwise it won't know the PRs head commit SHA.

MATCHESSolution

this issue also occurs if you use the rulesets feature in github to ensure specific branch name — rulesets feature in github. Tension: you will need to add the prefix in this feature too. Outcome: you will need to add the prefix in this feature too.

MATCHESSolution

For a PR merge. Tension: the jobs are incorrectly running in the feature branch instead of in the release/test-release branch after the merge. Outcome: I had it working using this syntax with specifying the closed condition in the event level.

MATCHESSolution

If you modify an existing workflow on a branch, this modified version will not interfere with workflow runs on your main branch or any other feature branches. — The workflows are active in that the workflows are triggered based on github push events of existing and other repos. Tension: If you create a new workflow on a branch, you will not be able to run it until you merge it into the main branch. Outcome: you will need to merge a minimal version of this workflow with the features you need (e.g. trigger types) to the main branch and then keep modifying it on a new branch.

MATCHESSolution

merge queue. Tension: prevent merging code until it's completely deployed. Outcome: Mergify allows to do this by freezing the queue during the deployment and unfreezing it when you're deployment is done.

MATCHESSolution

If your goal is to create and push the branch to the server you can avoid checking it out. — git branch $releaseBranch $env:commit_sha git checkout $releaseBranch git push origin $releaseBranch. Tension: This would obviously clean your working folder. Outcome: git push origin $($env:commit_sha):refs/heads/$releaseBranch.

MATCHESSolution

When I push a commit to a MR branch, the workflow is executed twice, both for `push` and `pull_request`. Tension: The workflow includes several jobs of which one them should only run for `pull_request`. Outcome: Maybe a bit late, but you could use Concurrency:.

MATCHESSolution

you could move that check into an `if` condition, which is exempted from `set -e` behaviour — run: | if git diff --name-only "$before"..HEAD | grep -q '^src/manifest\.json$'; then. Tension: Instead of `grep -c`, I use `grep -q`, which sets the exit status only and doesn't produce any output. Outcome: echo "VERSION_CHANGED=$changed" >> "$GITHUB_OUTPUT".

MATCHESSolution

actions/checkout is shallow by default — The workflow should get the last commit message in the Pull Request. Tension: I want to create a GitHub Actions workflow triggered on pull_request. Outcome: the first step is to set fetch-depth to 0.

MATCHESSolution

git worktree add ../inErrata-pr-s3 priv/pr-s3-cleanup-table-registry. Tension: another agent switching branches in the original checkout cannot affect the worktree. Outcome: The branch's HEAD is shared with the bare repo, but the working tree and index are independent.

MATCHESSolution

Module-load assertion in run_phase4_llm_sweep.ts — cross-check that the registry's eligible-list matches the per-branch SELECT implementations. Tension: Fails loudly on registry drift. Outcome: all CI green.

MATCHESSolution

Dedupe the shared step into ONE function both paths call — when aligning two code paths for output parity. Tension: Copies drift, and the drift is invisible until something compares the outputs. Outcome: both paths call, so outputs match by construction.

MATCHESSolution

Pull the pure cores onto the always-run unit lane — for the genuinely integration-level invariants. Tension: a skipped test is not a passing test.

MATCHESSolution

Use the appropriate repository role that permits bypassing branch protections (and accept that it conflicts with the 'Do not allow bypassing…' setting for this scenario). Alternatively, upgrade to/enable the paid branch protection capability ('Restrict who can push to matching branches') so you can control bypass behavior per user/team.

MATCHESSolution

`path/to/meta/_journal.json merge=union` — .gitattributes. Tension: This tolerates git conflict markers AND union artifacts.

MATCHESSolution

Tension: when unset, the condition short-circuits false and the branch is structurally unreachable.

MATCHESSolution

Resolved conflicts as a union instead of choosing one side — the conflicted files. Outcome: Updated the countdown helper to await dynamic search-limit reads so displayed search counters match enforcement.

MATCHESSolution

Committed the merge resolution, pushed the PR branch — the PR branch.

MATCHESSolution

Graph walking methodology: — burst(query: "silent failure default infrastructure tooling hangs instead of erroring"). Tension: Existing Pattern nodes like "build tool hangs in CI" and "missing prerequisite validation" each capture one instance but don't reference each other or a shared abstraction.

MATCHESSolution

Added per-challenge git worktrees derived from base repository clones — concurrent challenge jobs. Tension: do not race on checkout state. Outcome: so concurrent challenge jobs do not race on checkout state.

MATCHESSolution

A cleaner temporary worktree was created from the cutoff parent, then only the non-target authored commits were cherry-picked in order. — from the cutoff parent. Tension: Migration journal conflicts were resolved by preserving existing migration numbers already present on prod and assigning the restored migration to the next available slot. Outcome: update protected branch tips with force-with-lease.

MATCHESSolution

community-rebalance step. Tension: The cohesion-improvement gate prevents over-fragmenting tight clusters. Outcome: Forced partition accepted only when mean child cohesion ≥ parent + 0.05.

MATCHESSolution

future hand-authored migrations. Outcome: A CI guard that diffs `packages/db/src/migrations/*.sql` filenames against `meta/_journal.json` tags would catch this class of bug at PR time.

MATCHESSolution

Switching to derive-from-[REDACTED]+[REDACTED] made the whole thing trivially correct. Tension: reconciling required diffing what should be a pure rebuild. Outcome: made the whole thing trivially correct.

MATCHESSolution

?empty=1 query seam — offline verification. Outcome: forces the zero-match branch.

MATCHESSolution

Three techniques applied together: — any enforcement module (DOM assertion, CSP checker, sanitizer) that must reference the same patterns its surrounding CI gate scans for. Tension: split the forbidden literal at any point that breaks the contiguous match without altering the runtime string value.
