docs: record CS-RG as implemented and qualified on macOS

[novelKR]

Records CS-RG as implemented and qualified on macOS for one exact combination, from CodeSpace's CSRG-U6 qualification (report, novelKR/CodeSpace#99). This is the last step of CodeSpace's CSRG-U6 plan.

Why

On 2026-10-02 the owner directed CS-RG as units U1 to U6 in CodeSpace, outside the suspension of this plan's CSRG-C units. U1 to U5 are merged and verified. U6 qualified CS-RG under CodeSpace's frozen protocol on the qualification host, against release 0.1.0-6e7e065-94d85365, which DG-1 qualified and promoted on 2026-10-13 under the same policy (#34). CodeSpace's report merged as 241cf6c. The ledger still records CS-RG as in-progress, qualification not-run, with U6 active.

Result

Item	Result
Combination	CodeSpace ca306ee, code tree 32235f28…245f; DevGuard's client 6e7e065; release 0.1.0-6e7e065-94d85365, with DG-1's record fd4fed31…17a4 under the same host.toml and configuration fingerprint 8cbb019b…fc6f; Codex 6b9826e with CodeSpace's recorded patch, patched tree 1999937; Rust 1.95.0
Qualified	participation required in the runner modes in-process and uds with --runtime-bin, each with pipe and PTY executions; off and required workspaces in one gateway
Unsupported	uds with --runner-socket, required under --devguard status or without a usable launch helper, each refused before anything runs; Linux required until DG-LINUX
Functional matrix	45 of 45 scenarios passed, each governed launch matching this service's journal
Faults	27 of 27 cases passed against the fixture authority: no replay, no premature release
Authority failure	10 of 10 phases passed: control of running work kept while the authority was paused, stalled, restarted and stopped
Control path	qualified: both runner modes, three repetitions each, all twelve intervals passed under DG-1's cold load against this release; worst status p99 4.922 ms (target 500 ms) and worst termination acknowledgement p99 0.804 ms (target 1,000 ms); nothing stayed charged and the service kept its process throughout
Regressions	every stage that runs on macOS passed on the host (782 tests, and 189 in the macOS-only stages); Linux CI passed every job on ca306ee, linux-isolation included
Evidence	sealed on the host and listed with each MANIFEST.json SHA-256 in the report

Changes

File	Change
milestones.json	CS-RG implemented, qualification macos-qualified, with its qualified_combination; units as_of 2026-10-14 and CSRG-U6 merged-verified
AGENTS.md, docs/milestones.md	The current-state notes, and CS-RG's row names the qualification and its report
docs/planning/README.md, docs/ko/planning/README.md	The status sentence and the current-state note
docs/planning/milestones/CS-RG.md, docs/ko/planning/milestones/CS-RG.md	The dated current-state note records the qualification
docs/planning/verification.md, docs/ko/planning/verification.md	V-CS-RG names the qualification instead of "Future"
docs/planning/consumer-readiness.md, docs/ko/planning/consumer-readiness.md	R3 is permitted for the qualified combination and modes on that host

Korean counterparts reviewed; the planning-readme, planning-consumer-readiness, planning-milestones-cs-rg and planning-verification hashes recorded with scripts/check_docs.py record.

What does not change

• The suspension of this plan's CSRG-C units, and every historical text: the plan's units stay not started.
• DG-1's qualification and release.
• P1-RECOVERY, DG-LINUX, DG-CACHE and DG-ADAPTERS stay not-started. P1-RECOVERY starts only with the owner's separate authorization.
• No product code, contract, pin, dependency, CI policy or test changes.

Verification

At 7653c14, based on main at c077c74:

• python3 scripts/check_docs.py: passed, 18 reviewed pairs.
• python3 scripts/validate.py --stages whitespace,source-contract,documentation --diff-base origin/main: every stage passed.
• python3 scripts/ci_plan.py --base origin/main --head HEAD: profile affected, 12 normative paths and no component, so the repository stages whitespace, source-contract and documentation run and Rust does not.
• python3 -m unittest discover -s scripts -p 'test_ci_*.py': 95 tests passed.
• milestones.json parses, and its qualified_combination matches CodeSpace ca306ee and its Codex gitlink 6b9826e3, DevGuard's 6e7e065, and the patched tree that CodeSpace's report records.
• CI on this head: run 38525490441 passed the plan, the repository checks and the required checks; the plan skipped contracts, as nothing outside the documentation and the ledger changed.

Rollback

Revert the merge (git revert -m 1 <merge commit>). The ledger then records CS-RG as in progress again, while CodeSpace's report stays the record of the runs.
