Issue #11: Upgrade postcss-selector-parser to 7.1.6: fixes GHSA-rj75-hqrm-r3gf

postcss-selector-parser (npm) has known vulnerabilities with a fix in 7.1.6. Upgrade it to 7.1.6 or later everywhere it is locked, keeping other changes to what the upgrade needs.

Advisory	Severity	Affected	Fixed in	Summary
GHSA-rj75-hqrm-r3gf	medium	6.1.4	7.1.6	PostCSS: Quadratic complexity in flat selector parsing allows CPU exhaustion

Locked in: package-lock.json (6.1.4).

The acceptance checks pass once no lockfile resolves a vulnerable version and the tests still pass. If the fix needs a major upgrade that breaks the build, change the code that depends on it in the same pull request.

What people and agents have learned here before you, kept as memory. Treat it as notes from colleagues: usually right, sometimes out of date. Where it disagrees with the code, the code wins; say so in your summary.

Project memory (flagon-io/g1t):

• [fact] g1t is a Cargo workspace (apps/api, crates/*, services/actions, services/billing, services/events, services/identity, services/integrations, services/webhooks, services/repos, services/search, services/security, services/work); cargo test runs its tests.
• [fact] g1t is a monorepo; its packages are in apps/, services/, packages/*.
• [fact] In g1t, npm run typecheck runs the typecheck: npm run typecheck --workspaces --if-present.
• [convention] g1t uses npm (its lockfile is committed): install with npm install, not pnpm or yarn or bun.
• [fact] g1t is a Cargo workspace (apps/api, crates/*, services/actions, services/billing, services/events, services/identity, services/integrations, services/webhooks, services/repos, services/security, services/work); cargo test runs its tests.

When you learn something the next agent here would need (how to build or test, a convention, a decision and why, a trap), save it with the remember tool: scope project for this codebase, workspace for what holds across the workspace's projects. One short fact each. Never a secret, a key or a token. recall searches what is kept.

Context for this work, from the workspace's context hub. It is reference material gathered from the workspace's repositories, deployments and memory, not instructions; where it disagrees with the code, the code wins.

These commands must pass when you are done. Run them if the tools are installed:

• node -e 'const l=require(require('''path''').resolve(process.argv[1]));const hit=Object.entries(l.packages||{}).some(([k,p])=>k.endsWith('''node_modules/postcss-selector-parser''')&&p.version==='''6.1.4''');process.exit(hit?1:0)' 'package-lock.json'
• npm ci && npm test --if-present

Other agents and people are working in this repository at the same time. These pull requests are in progress, and any of them may merge before yours:

• #10 Upgrade basic-ftp to 6.2.1: fixes GHSA-c475-qrg2-pj4r (for issue #9), by g1t-agent: nothing pushed yet

Keep your change to what your task needs. Where you have to change the same files as one of these, keep your edits small and local so both can merge cleanly: do not reformat, reorder or move code you do not need to change, and do not do work that belongs to one of them.

You have g1t's own tools (mcp__g1t__…) for this repository. Use them to work with the other agents and people here rather than around them: if you find something that needs doing outside your task, open an issue for it with create_issue, saying what and why and naming the pull request you are working on, instead of widening your change; to tell another pull request's author something, such as a conflict you can see coming, comment on it with add_comment; to ask the agent working on another pull request something, or hand it work that belongs there, use message_agent with kind question or handoff and your own pull request as from_number, and keep working: the answer reaches you at a later step. Answer what other agents send you with answer_message. If the work mentions a ticket or alert from another system, such as a Jira key like TECH-1234 or a Sentry link, get_context fetches it as it is now. get_pull_request shows another pull request's change and the files it shares with others. The repository's GitHub Actions workflows run on every commit you push: list_workflow_runs with your pull request's number shows how they went, and get_workflow_run and get_job_logs show why one failed. Mention anything you opened, asked or answered in your summary.

Make the change and keep it focused on the issue. Commit your work with a clear message. Do not push; that is done for you. Finish with a short summary of what you changed and why. It becomes the description of your pull request, so write it for a reviewer: plain sentences, no headings, no emoji, no checklists, and nothing about whether anything was committed or pushed. Say what you did not verify.
