chore: audit residue — dead scripts, duplicated /skill: grammar, chat-readiness remnant

[Astro-Han]

Found by a repo-wide simplification audit; zero-consumer claims re-verified with git grep -aI. Four small independent cleanups bundled here:

1. scripts/check-astryx-alignment.mjs (130 lines): no execution path — not in root package.json scripts, any of the 8 workflows, or scripts/ci-test-plan.mjs (which wires the sibling check-astryx-surface-inventory.mjs instead). Repo-wide references: the file itself and one doc line. Its astryx-allow: raw-button escape-hatch comment still spreads in sources.
2. scripts/deepseek-live-cost-baseline.mjs (2960 lines): only reference is the npm alias cost:deepseek-baseline; zero invocations, zero workflow/doc references outside docs/archive/ (which declares itself non-current). Couples to Runtime/Storage internals and is the last user of the legacy compaction capability (see the History Compact V1 issue).
3. packages/cli/src/skill-token.ts: a near-verbatim second authority for the /skill: token grammar duplicating packages/runtime/src/skill-invocation.ts. The CLI copy's three main symbols have zero consumers; its two importers use only skillInvocationPrefixAt and a constant re-export, while the CLI already imports @maka/runtime/skill-invocation in 3 places.
4. apps/desktop/src/main/chat-readiness.ts: the admission gate is residue — the only production importer is main-window.ts importing errorMessage; assertSessionCanSend / ensureSessionCanSendOrRebind have no production callers. Collapse to the error helpers actually used.

Claim this issue #3218. I will only be handling the /skill: duplicate CLI helper task to avoid conflicting with the cleanup of the other three items.

Has this issue been resolved? I want to claim this issue.

@Xinbeok I checked the current state of this issue on main and the related PRs — it's already fully covered by existing work, so I wouldn't claim it:

• Add Rive workflow Maka tool #1 scripts/check-astryx-alignment.mjs and Harden runtime, storage, gateway, credentials, and IPC inputs #2 scripts/deepseek-live-cost-baseline.mjs — deleted in PR chore: remove audit residue #3242 "chore: remove audit residue" (open, Closes this issue).
• Extract runtime kernel boundaries and durable AgentRun recovery #3 packages/cli/src/skill-token.ts — also covered in PR chore: remove audit residue #3242, and PR chore(cli): remove duplicated skill token helpers #3267 "chore(cli): remove duplicated skill token helpers" touches the same files.
• Document Runtime v2 architecture evolution #4 apps/desktop/src/main/chat-readiness.ts — already removed on main by merged PR refactor(desktop): remove superseded local authority paths #3252.

So the only remaining step here is reviewing/landing those PRs, not writing new code — a new claim would just duplicate #3242 and overlap #3267.

That said, it's great that you're actively looking for work to contribute! I ran a quick pass over the open backlog and these look claimable right now (no assignee, no open PR, no claim comment at the moment):

• feat(desktop): add an operational topology view for Agent Graph #2596 feat(desktop): add an operational topology view for Agent Graph — self-contained Desktop UI feature.
• eval: publish and pin the egress proxy image by registry digest #2953 eval: publish and pin the egress proxy image by registry digest — clearly scoped follow-up (may need coordination on publish permissions).
• chore(repo): promote the de-facto scope taxonomy into area/* labels #2441 chore(repo): promote the de-facto scope taxonomy into area/* labels — low-risk repo housekeeping (governance-adjacent, worth confirming direction with a maintainer first).

I verified these against the current repo, but the maintainers are fast, so it's worth replying to claim quickly. Good luck!
