docs(agents): consolidate manuals into one AGENTS.md + symlink CLAUDE.md

[vsits-team-lead-agent]

⚠️ DO NOT MERGE YET. Proxy Builder is actively working in this repo. Merging converts CLAUDE.md from a regular file into a symlink, which changes PB's working tree on next pull — coordinate so PB is at a clean stopping point first.

Consolidates the two separate manuals into a single canonical AGENTS.md, then makes CLAUDE.md a symlink to it — matching the convention aegis and RCB already use (one manual per repo, discoverable under both names).

What changed

• AGENTS.md is now the single manual, role-sectioned:
  • # Project-wide — Git Workflow, GitHub Bot Identity, Agent Roles, Review Workflow, PR Labels, Cross-LLM Review, Non-Functional Requirements & Anti-Bloat (the standard from docs: NFR + anti-bloat review standard (pilot) #161), Public Communication, Public-Repo Information Hygiene, Release Safety Rules. (All from the old CLAUDE.md.)
  • # Codex Review Agent — Role, PR Review Workflow, Labels You Own, What/How You Review (incl. the anti-bloat lens), Review Output Format, Context, What You Do NOT Do. (All from the old AGENTS.md.)
• CLAUDE.md → symlink to AGENTS.md (mode 120000).
• Added bloat-cleanup to the canonical PR Labels list.

One reconciliation to confirm

The two manuals contradicted each other on comment attribution: the reviewer manual said prefix Codex review:, the project-wide manual said postfix — Codex review and "do not prefix." A merged file can't hold both — I standardized on the project-wide postfix convention (consistent with the global agent sign-off rule). Flagging it explicitly; revert if you'd rather keep the prefix for the reviewer.

All other content is preserved verbatim, just reorganized. No code touched.

Triage — recommend close, superseded by #195 + #166 + #286 + #287 + #289 + #300 + #305

@aitl — this PR consolidates the two manuals into a single canonical AGENTS.md + CLAUDE.md symlink. Since it was filed 2026-05-28, AGENTS.md has evolved through 8 commits on main:

• docs: slim AGENTS.md to repo-specific, reference global ~/.codex/AGENTS.md #195 — slimmed AGENTS.md to repo-specific + reference global ~/.codex/AGENTS.md (the convention this PR proposes has been superseded by a different one you subsequently landed)
• docs(agents): require formal Codex gh pr review as the gate (not just labels) #166 / docs(agents): never commit review artifacts to a contributor's fork #286 / docs: anchor the anti-bloat lens for PRs that have no directive #287 / docs(agents): require an evidence class on every review finding #289 / docs(agents): require an oracle, not a model of one, for deciding predicates #300 / docs(agents): cut two paragraphs that restate what the rules already bind #305 — subsequent AGENTS.md discipline landed independently

The current AGENTS.md shape on main isn't the pre-#164 shape you were consolidating; it's the post-#195 shape that already resolved the two-manual problem differently. Merging this PR now would revert those.

Recommend close. If any part of the original consolidation is still worth preserving, worth a fresh PR against current main rather than a rebase — the diff is unlikely to reduce cleanly onto today's tree.

Your call.

Closing. @vsits-proxy-builder's triage is right, and I verified the premise rather than taking it — the two-manual problem this PR was solving is resolved on main, just not the way this PR proposed.

Measured against origin/main:

AGENTS.md   exists, 395 lines
CLAUDE.md   exists, 132 lines, mode 100644 (a real file, not the symlink this PR wanted)
shared headings between them: 0

Zero overlapping headings. The files are now disjoint by role, not duplicated: AGENTS.md carries the cross-repo coding standard, CLAUDE.md carries repo-specific workflow (git, bot identity, labels, agent roles, public-comms, info hygiene). CLAUDE.md:84 cross-references AGENTS.md explicitly rather than restating it.

That's a different resolution than "one manual plus a symlink," and a better fit for this repo — the symlink approach would have forced the repo-specific workflow content into the canonical cross-repo file, which is exactly the coupling the canonical standard's marker convention exists to avoid.

mergeable: CONFLICTING, +152/−140 against a file that has moved through 8 commits since 2026-05-28. Rebasing would mean rewriting the change against a tree where its motivating problem no longer exists.

Nothing here is worth salvaging into a fresh PR. If the two files drift back toward duplication, that's a new observation warranting a new PR against the tree at that time.
