After: Magica's 4 commits (94cde633e, c65fb34ee, d1f6f2b19, 61ebf2c34) cherry-picked onto 669cdf42c, diff vs the gated tree limited to drift paths, range-diff in scratch.

Plan: reuse P1 proxy template/runner under --proxy, enforce three-unit re-install checks and proxy→bus→Console starts, cover refusals and both named mutants.

+# Row 334 — Case 2 proxy unit (#1832)
+
+## Design at 78b69e1e6 (2026-10-25)
+
+Scope: mos-1616 ruling 1, P1 item 7 only. No template, runner, PIN,
+user-unit path, config/secret access, or live unit changes.
+
+Current references: case2-unit.sh template seams 44-45, defaults 54-57,
+render 435, check_unit 489, render checks 548-551, re-install 553-573,
+active-state capture 576-580, writes/start/report 583-610.
+case2-install.sh Next: 231. P1 instance.sh PROXY_UNIT 86;
+bus-service.sh dependency insertion 93. P1 template ExecStart 13;
+run.mjs validates config 11-13 and calls startVerifiedProxy 14;
+runner.mjs refuses proxy-not-configured 8, verifyInstall 9;
+settings.mjs verifyInstall 23-30 refuses proxy-install-invalid for a hash
+mismatch. run.mjs catches that and exits 3. P1 item 7 is rows doc 86-90;
+row209 entry check 2 remains 32-36.
+
+Add bare --proxy and CASE2_PROXY_TEMPLATE. Render P1's unmodified template
+with copy, PATH, node and deleted CONFIG_ENV; add User/Group plus bus's four
+hardening lines, no capabilities or EnvironmentFile. check_unit proxy uses
+exact node + copy/packages/model-proxy/src/run.mjs, NoNewPrivileges=yes,
+and every common refusal. Restrict CLAUDE_ENV expectation and capabilities
+to their existing bus/webui kinds. Insert bus Wants/After immediately after
+Description exactly as P1 does, only with --proxy. No-proxy output remains
+byte identical.
+
+Re-install checks all selected units against render modulo copy id and
+compares every installed copy id. Existing proxy without --proxy refuses
+before writes, including a dangling symlink. No deletion. Enable all
+selected units, then start proxy, bus, Console. Capture/report already-running
+proxy with the others and name all three in restart-together guidance.
+Change only case2-install.sh's closing Next: to tell root to add --proxy
+when the config has a proxy section.
+
+Tests first, unrun until Sage CLEAR: byte-identical non-proxy renders;
+proxy content and exact dependencies; each common/proxy check_unit refusal
+by message; rendered ExecStart wrong-PIN refusal proxy-install-invalid rc 3;
+three-unit re-install and mixed copies including proxy-only mismatch;
+installed proxy without flag preserves files; start order and failures;
+already-running report; install Next: guidance. Named mutants: remove bus
+After=; direct binary ExecStart bypassing run.mjs. Whole-file run list will
+be derived from static imports before any run; case1-accept stays off.
+
+P2 is not present on this base (row331 still in progress); inspect landed
+P2 refusal code before final handoff. No flag/config false-positive check:
+P1 startVerifiedProxy refuses proxy-not-configured, run.mjs exits 3.
+
+## Slot / session
+
+No tests run. CLEAR pending from Sage. Canonical queue start initially
+refused: lock held by magica-331-start since 03:57:01.839Z. Same operation
+will be retried after a minute; no lock manipulation.
+
+Correction to line references above: row209 entry check 2 is 29-33;
+run.mjs config validation 8-10, runner call 11, refusal exit status 18.
+case2-unit.sh is byte-identical to brief base 58b2bbb3a (sha256
+4ca8769134d83ee391bcc73af5bd042b9e2b161cac22821d29fcca710a9afad4).
+P1 paths named above have no diff between 86cb5c221 and 78b69e1e6.
+Own-worktree root npm ci --ignore-scripts --no-audit --no-fund: rc 0,
+128 packages. No tests invoked.
+
+Sage sage-4346 accepts design, authorizes writing RED tests then code while
+holding all runs until CLEAR. Tests were written first, then implementation;
+no RED run has occurred. Installed proxy without --proxy explicitly refuses
+and preserves bytes; dangling symlink also refuses, never deletes. P2 code
+remains pending until row331 lands. Both wrong-flag P1 runner paths covered.
+
+Import-manifest correction: expanded traversal to include multiline import
+and export-from edges (the business/library barrel modules). Closure is
+53 local modules; only the same two test entrypoints occur. The run list
+is unchanged; this is source inspection, no tests executed.
+
+Queue start completed: rockerduck-334-start rev4079, row334
+briefed→in-progress. git diff --check passed. Implementation, tests and
+import manifest prepared; no tests, commits or pushes performed. Verification
+awaits Sage's CLEAR; no live host/instance access occurred.
+
+## RED run authorized by sage-4387, 2026-10-25 04:21Z
+
+Whole files, sequential, with each corresponding script temporarily restored
+from 78b69e1e6 and its implementation restored by EXIT trap afterwards:
+- case2-unit.test.mjs: rc1, 81 tests, 48 pass, 33 fail, 0 skips;
+  TMPDIR=/mnt/storage/scratch/tmp/QD3vp5, nice=19, 77995.928687 ms.
+  All 47 old tests pass; new no-proxy byte equality passes. 32 new failures
+  encounter baseline unsupported --proxy usage rc4; dangling installed proxy
+  symlink case gets rc0 rather than refusal because baseline ignores it.
+- case2-install.test.mjs: rc1, 28 tests, 27 pass, 1 fail, 0 skips;
+  TMPDIR=/mnt/storage/scratch/tmp/YAGfKJ, nice=19, 10016.247032 ms.
+  All old tests pass. New Next: guidance assertion fails because baseline
+  lacks add --proxy when the config has a proxy section.
+
+Every failure and cause is listed in red-results.txt; full plain-text
+outputs in red-unit.log and red-install.log. Absolute node/test paths used.
+Implementation restored, git diff --check clean. No old-test red, rerun,
+assertion change, GREEN or mutant run. P2 check still pending row331.
+Slot returned to Sage; GREEN and mutants await separate CLEAR.
+
+Sage sage-4390 accepts clean RED and explicitly authorizes committing and
+pushing this candidate to rockerduck/row334 before GREEN. No force push.
+GREEN and mutants remain held for a separate CLEAR after row331 lands;
+then rebase onto landed P2 and check its missing-flag refusal code.
