fix(#770): mark dead configs deprecated + restore owner trust-anchor to curated System view

[mindfn]

Part of #770 (items E "dead-config marking" and F "DEFAULT_OWNER_USER_ID remediation" from the staged cleanup).

What

Item E — dead-config marking (registry entries retained):

• New EnvDefinition.deprecated?: string field — mirrors the field the frontend EnvVar type already declares; the "已废弃" badge in EnvSubComponents was wired but had no API data source until now. Registry entries are not deleted (registry stays the canonical inventory; physical removal remains a maintainer decision).
• 7 vars marked with evidence-backed reasons:
  • MODE_SWITCH_REQUIRES_APPROVAL — Mode-system consumer (ModeOrchestrator) was removed in the F101 Mode v2 rework (2dfece987), before the TD117 registry backfill (b58106d0d) re-registered the then-already-dead var; no live consumer in the current tree.
  • GITHUB_REVIEW_IMAP_USER/PASS/HOST/PORT, GITHUB_REVIEW_POLL_INTERVAL_MS, GITHUB_REVIEW_IMAP_PROXY — the IMAP mail-poll channel was removed in the v0.9.0 sync (sync: cat-cafe 8f1f1fd95 → clowder-ai (v0.9.0) #596); PR review feedback now flows through register_pr_tracking-driven GitHub API polling (ReviewFeedbackTaskSpec). Note: GITHUB_WEBHOOK_SECRET belongs to the separate Repo Inbox webhook and is not this channel's successor.
• Audit method: literal scan across all file types (incl. shell/skills), dynamic-concatenation heuristics, and git history tracing. This caught one false positive from a TS-only scan: HYPERFOCUS_THRESHOLD_MS is consumed by cat-cafe-skills/hyperfocus-brake/hook.sh and stays unmarked.
• User-facing entry points closed in the same PR: SETUP.md, SETUP.zh-CN.md, .env.example no longer instruct configuring the removed IMAP watcher; the PR-review-notification sections now describe the actual GitHub API polling path.

Item F — DEFAULT_OWNER_USER_ID trust-anchor projection (presentation-only):

• Added to SYSTEM_VARS (security group, read-only, restartRequired: true) — the issue's proposed System allowlist explicitly lists it ("owner/trust-anchor values that explain write/auth behavior") but the feat(#770): curated System Settings with inline editing #1280 curated projection missed it.
• Description/defaultValue now explain the unset ⇒ single-user-local-mode semantics so the read-only display is interpretable.
• runtimeEditable stays false, now pinned by a test invariant: every env-write endpoint derives its guard from this var, so runtime editing would enable privilege bootstrap (a session granting itself ownership). Full security analysis (13 consumer files, 6 behavioral endpoint classes) posted as an issue comment on Proposal: narrow System env settings and move connector/service config to owner stores #770.

Test invariants added (12 assertions)

• deprecated vars are never runtimeEditable, never in SYSTEM_VARS, always keep their registry entry, always carry a non-empty reason
• buildEnvSummary carries deprecated through to the API payload (badge data source)
• DEFAULT_OWNER_USER_ID: read-only + security group + restart-required + explains single-user semantics

Verification

• pnpm check (incl. feature-truth gate) ✅ · api build ✅ · env-registry tests 70/70 ✅ · web system-settings wiring 5/5 ✅
• Controlled A/B on the full api suite (same worktree, only this diff toggled): failure sets identical in both directions — zero regressions introduced.
• Local cross-review: 2 rounds (sol), findings resolved — incl. correcting the deprecated reasons' replacement-path attribution and closing the user-facing doc entry points.

Follow-up

A second PR (section projection + control metadata for module settings, already reviewed locally) will be submitted after this one merges — kept separate so each PR stays on one capability boundary.

Formal maintainer review for exact HEAD c8590f23ed6ce4966872d350e4b085d9d3d7ff7c

Verdict: CHANGES_REQUESTED

[P2] Correct the MODE_SWITCH_REQUIRES_APPROVAL history and #832 provenance before merge.

The current dead-code conclusion is valid, but the diff and PR narrative overstate the evidence as “no consumer ever existed.” Public history disproves that: commit 2dfece9873 deletes active reads from ModeOrchestrator.ts plus its tests, and that commit is an ancestor of registry-backfill commit b58106d0d4. Also, bare #832 resolves in this repository to unrelated clowder-ai issue #832; the TD117 backfill came from a different repository and is represented in public history by b58106d0d4.

Please update the user-visible deprecated reason and test/PR provenance to say that the Mode consumer was removed before the registry backfill, and remove or disambiguate the bare #832 reference. The row can remain deprecated: the exact-HEAD tree has no live consumer.

Everything else in scope passed:

• the six IMAP variables have no live TS/shell/skill consumers; #596 removed the watcher/bootstrap and the current register_pr_tracking → ReviewFeedbackTaskSpec GitHub API polling path is present;
• deprecated flows through buildEnvSummary into the frontend EnvVar contract and existing badge;
• DEFAULT_OWNER_USER_ID remains runtimeEditable: false; PATCH /api/config/env rejects it via the fail-closed registry predicate, and both Settings projections are read-only;
• all five GitHub checks are terminal green; source risk-check reports no 1224-class migration and correctly classifies env-registry.ts as high-risk/manual-port for later intake.

Fix custody remains with mindfn; no maintainer fixup is authorized.

P2 fixed in f652dd3baa2d6f1b9899b116edef7482944173e2 — thank you for the precise history correction.

What changed:

• Registry deprecated reason now states the accurate lifecycle: Mode-system consumer removed in the F101 Mode v2 rework (2dfece987), before the TD117 registry backfill (b58106d0d) re-registered the then-already-dead var. Bare #832 dropped (identified by commit SHA to avoid cross-repo issue collision).
• Test-file provenance comment updated to the same narrative.
• PR description's dead-config bullet corrected accordingly.

Root cause acknowledged: my git log -S evidence scan was piped through head -5; the consumer's full lifecycle (F11 introduction 3099babc3 → F101 removal 2dfece987) sat below the cut, and five visible registry-only commits were wrongly extrapolated to "no consumer ever existed." Independently re-verified your ancestry claim (git merge-base --is-ancestor 2dfece9873 b58106d0d4 ✓) before rewording.

Verification on the new HEAD: api build clean, env-registry 70/70, biome clean. Diff is reason-text + comments only — no behavior change.

Formal maintainer re-review for exact HEAD f652dd3baa2d6f1b9899b116edef7482944173e2

Verdict: APPROVED

The author delta fully resolves the prior P2:

• MODE_SWITCH_REQUIRES_APPROVAL now accurately records that its ModeOrchestrator consumer was removed by 2dfece987, before TD117 registry backfill b58106d0d re-registered the already-dead variable.
• the ambiguous bare #832 provenance is removed from the current PR body, runtime metadata, and focused test commentary.

Re-verification:

• exact-HEAD API build: PASS;
• packages/api/test/env-registry.test.js: 70/70 PASS;
• F101/F102 and historical F011 anchors resolve to real feature docs;
• GitHub Build, Directory Size Guard, Lint, Test (Public), and Test (Windows): all terminal SUCCESS;
• no new behavioral, security, contract, or intake-classification delta.

Direction remains approved under clowder-ai#770. If merged, intake remains absorbed-via-manual-port/high-risk for env-registry.ts, preserving the full home registry, fail-closed editability, both Settings surfaces, and the cat-cafe#3596 owner-gate semantics. Merge remains a separate CVO-gated action.
