# CLI-066: Env-var-only startup — honor the product's own zero-config promise

## Problem

The product's guidance promises env-var-only startup in two places (verified 2026-06-11 on
npm-installed `3.0.0-beta.73`, product verification L1/L3):

- `robota diagnose`: "Set ANTHROPIC_API_KEY or run: robota --configure"
- `robota init` non-TTY fallthrough: "Set your API key via environment variable instead:
  ANTHROPIC_API_KEY=<key> robota"

But with `ANTHROPIC_API_KEY` exported and no provider profile, `robota -p "..."` fails with
"No provider configuration found" (exit 1). The advertised zero-config path does not exist:
`resolveActiveProvider` (agent-framework `provider-merge.ts`) only consults settings
documents, never provider-definition defaults, even though every cloud definition already
carries `defaults.model` and `defaults.apiKey: "$ENV:<NAME>"` (e.g.
`anthropic/provider-definition.ts:34-37`).

## Architecture Review

### Affected Scope

- `packages/agent-framework` / `src/command-api/provider/provider-factory.ts` (and/or
  `provider-merge.ts`) — when no settings profile resolves, synthesize an in-memory profile
  from the first provider definition whose `defaults.apiKey` `$ENV:` reference resolves
- `packages/agent-framework` / `docs/SPEC.md` — resolution order contract
- `packages/agent-cli` / `docs/SPEC.md` — startup contract; "No provider configuration"
  error now means "no profile AND no recognized env key"
- `packages/agent-cli` / startup notice — one stderr line when running on an env-synthesized
  profile

### Alternatives Considered

1. **Definition-defaults fallback inside provider resolution (chosen).**
   - Pro: uses data that already exists (`defaults.model` + `defaults.apiKey` env reference
     per definition); deterministic priority = definition order (anthropic, openai, gemini,
     gemma, qwen, deepseek); zero persistence side effects; settings profiles always win, so
     existing users are unaffected.
   - Con: behavior depends on ambient env vars — must be announced via a startup notice line
     so users know which provider/model was auto-selected.
2. **Auto-write a settings profile on first env-key detection.**
   - Pro: subsequent runs are explicit and inspectable.
   - Con: a read path silently mutating user config violates least surprise; conflicts with
     `--no-session-persistence`-style expectations; harder to undo.
3. **Remove the env-var guidance from diagnose/init messages (no code path).**
   - Pro: smallest change.
   - Con: kills the zero-config onboarding that diagnose/init/welcome UX was built around
     (CLI-049/050 restored these flows precisely for first-run UX); a worse product, not a
     fixed one.

### Decision

Alternative 1. This is not a new contract — it makes the code honor the contract the product
already advertises. Priority on multiple set env keys = definition order with the selected
provider named in the startup notice (`Using anthropic (claude-…) via ANTHROPIC_API_KEY —
run robota --configure to persist a profile.`). Env access is injected (parameter defaulting
to `process.env`) for testability. Explicit non-goals: no persistence, no interactive
prompt change.

## Solution

1. In provider resolution (agent-framework): after settings-document resolution returns
   nothing, iterate `providerDefinitions` in order; for each definition where
   `defaults.apiKey` matches `$ENV:<NAME>` and `env[<NAME>]` is non-empty and
   `defaults.model` exists (and `defaults.baseURL` exists if the definition requires one),
   return a synthesized `IProviderConfig` from the definition defaults, flagged
   `source: 'env-default'` (typed field, SSOT in the config type) so callers can render the
   notice.
2. `agent-cli` startup: when the resolved config is env-synthesized, write the one-line
   notice to stderr (print mode) / terminal (TUI) — never the key value.
3. No settings file is written. Profile in settings always wins (resolution order:
   settings → env-default → error).
4. SPEC updates: framework resolution order; CLI startup contract and error meaning.

_Correction during implementation (within the approved Decision): the draft's sibling scan
misread the actual definition data. Verified against `packages/agent-provider/src/*/`
(2026-06-12): **openai has `defaults.model: undefined`** by deliberate policy (model
catalog status `unavailable` — "discovered live from GET /v1/models"), so it cannot be
synthesized; **gemma's `defaults.apiKey` is the literal `'lm-studio'`**, not an `$ENV:`
reference, so it is excluded by the candidate rule itself; **qwen and deepseek carry
complete defaults** (`$ENV:` apiKey reference + model + baseURL), so they ARE synthesizable
— their baseURL comes from their own defaults, not from the environment. The data-driven
candidate rule in Solution step 1 is unchanged; only the draft's expected membership list
was wrong. Synthesizable set: anthropic, gemini, qwen, deepseek. Excluded: openai (no
default model — `OPENAI_API_KEY` alone still gets the configure guidance), gemma (literal
key). TC-02/TC-05 reworded accordingly._

## Affected Files

- `packages/agent-framework/src/command-api/provider/provider-factory.ts`
- `packages/agent-framework/src/command-api/provider/provider-merge.ts` (if resolution lives
  here)
- `packages/agent-framework/src/command-api/provider/__tests__/`
- `packages/agent-framework/docs/SPEC.md`
- `packages/agent-cli/src/cli.ts` (notice emission)
- `packages/agent-cli/docs/SPEC.md`

## Completion Criteria

- [x] TC-01: no settings profile + injected env `ANTHROPIC_API_KEY=x` → resolution returns
      anthropic config with definition default model, the key resolved from the injected
      env (profile-path parity — `resolveActiveProvider` also returns resolved keys via
      `normalizeProviderConfig`), `source: 'env-default'`, and the env var NAME carried in
      `sourceEnvVar` for the notice. _Corrected during implementation: the draft said the
      key "stays a `$ENV:` reference", but provider creation and the subagent runner
      factory consume resolved keys (verified by a real 401 from the literal reference
      string in the live scenario run); the env name moved to a dedicated typed field so
      the notice never touches the value._
- [x] TC-02: multiple synthesizable env keys set (`ANTHROPIC_API_KEY` + `GEMINI_API_KEY`) →
      anthropic wins (definition order). _Reworded during implementation: the draft paired
      anthropic with openai, but openai is not synthesizable (no default model) — see the
      Solution correction note._
- [x] TC-03: settings profile present + env key set → settings profile wins (regression)
- [x] TC-04: no profile + no recognized env key → existing "No provider configuration found"
      error unchanged (regression)
- [x] TC-05: definitions failing the candidate rule are never synthesized — gemma (literal
      non-`$ENV:` apiKey default) and openai (no default model) produce no synthesis even
      with their env vars set; qwen/deepseek synthesize using their own complete defaults
      (incl. baseURL). _Reworded during implementation per the Solution correction note: the
      draft's "local 3종 excluded" premise misread the definition data._
- [x] TC-06: startup notice line printed exactly once when running on an env-synthesized
      profile, naming provider, model, and env var name — never the key value
- [x] TC-07: framework + CLI SPEC.md document the resolution order
      settings → env-default → error

## Test Plan

Derived strategy (BEHAVIOR + cli/typescript): unit tests with injected env; integration for
the notice line.

## Tasks

- [x] `.agents/tasks/completed/CLI-066.md` — archived at GATE-COMPLETE (T1~T8 all complete, TC-01~TC-07 매핑)

## Evidence Log

### [GATE-WRITE] — ✅ PASS | 2026-06-11

**Status upgrade:** draft → review-ready

- Frontmatter: file begins with `---` YAML block; `status: draft` present; `type: BEHAVIOR` is one of the 11 allowed prefixes; `tags: [cli, typescript]` present.
- Problem: concrete symptom present (`robota -p "..."` fails with "No provider configuration found", exit 1, on `3.0.0-beta.73`); reproduction condition present (`ANTHROPIC_API_KEY` exported, no provider profile); no "TBD"/"TODO" or vague single-sentence description.
- Architecture Review Checklist: all 4 items `[x]`; sibling scan `[x]` with completion evidence (6 definitions scanned — 3 cloud synthesizable, 3 local excluded for baseURL requirement); Alternatives Considered has 3 entries, each with pro and con; Decision references the driving trade-off (honor advertised contract vs. silent config mutation vs. removing the promise; ambient-env dependence mitigated by startup notice).
- Completion Criteria: all 7 items have TC-N prefixes (TC-01–TC-07); at least one criterion per sub-item (resolution, priority, regression x2, local exclusion, notice, SPEC docs); each uses observable behavior form; no banned vague phrases ("works correctly", "no errors", "implemented", "displays correctly") found.
- Test Plan: section present; 7 rows match 7 TC-Ns in Completion Criteria (count matches); every row has non-empty Test Type and Tool/Approach with no "TBD"; the single manual row (TC-07) has a non-empty Notes entry explaining why automation is not applicable (doc change reviewed in PR diff).
- Structure: `## Tasks` section present with placeholder; `## Evidence Log` section present and empty at gate run; no `## Status` or `## Classification` sections in the body.

### [GATE-APPROVAL] — ✅ PASS | 2026-06-11

**Status upgrade:** review-ready → approved

- Explicit approval in current conversation: user replied "승인함" (verbatim) on 2026-06-11 to the agent's "## 설계안 요약 (승인 요청)" message that requested approval of exactly the four GATE-WRITE-passed specs (CLI-063/064/065/066) and stated "4건 승인해 주시면 GATE-APPROVAL → 구현(TDD) → PR 순서로 진행합니다."
- Direct, unambiguous, directed at this spec: the approval message summarized CLI-066's design decisions specifically (in-memory env-default profile synthesis from definition defaults in definition order, no persistence, settings profile always wins, one-line provider/model/env-var startup notice without key value, local-type definitions excluded) and flagged it as containing a product-direction decision ("제품 방향 결정 포함"); "승인함" confirms all four presented designs including this one — not a clarifying answer, not silence, not approval of a different item.
- No post-approval modification: frontmatter (`type: BEHAVIOR`, `tags: [cli, typescript]`) and Architecture Review content match what was summarized for approval; last Evidence Log entry before this gate is GATE-WRITE (2026-06-11); approval was given after spec content was authored and summarized.
- NON-COMPLIANCE trigger check: no implementation started before this gate — `.agents/tasks/CLI-066.md` does not exist; no uncommitted changes in `packages/agent-framework/src/command-api/provider/` or `packages/agent-cli/src/cli.ts`.

### [GATE-IMPLEMENT] — ❌ FAIL | 2026-06-12

**Status remains:** approved
**Failed criteria:**

- Tasks correspond to Completion Criteria: `.agents/tasks/CLI-066.md` exists (criterion 1 met) and its path is recorded in `## Tasks` (criterion 2 met); T1–T7 cover TC-01–TC-07 by label, but T5 and T2 contradict the approved spec content. T5 defines the exclusion rule as "no `$ENV:` apiKey default (gemma) or no default model (openai)", while TC-05 and the approved sibling scan state all three cloud definitions (anthropic/openai/gemini) carry `defaults.model` + `$ENV:` apiKey and only local-type definitions (gemma/qwen/deepseek) are excluded due to the baseURL requirement — T5 wrongly removes openai from the synthesizable set. T2 tests priority with "anthropic before gemini", while TC-02 specifies `ANTHROPIC_API_KEY` + `OPENAI_API_KEY` with anthropic winning — consistent with T5's incorrect model rather than the spec. Implementing per the tasks file would fail TC-02/TC-05.
  **Required action:** Rewrite T2 and T5 in `.agents/tasks/CLI-066.md` to match TC-02 (anthropic + openai env keys, anthropic wins by definition order) and TC-05 (local-type definitions gemma/qwen/deepseek excluded — baseURL requirement; cloud definitions including openai remain candidates), then re-run GATE-IMPLEMENT.
- NON-COMPLIANCE trigger check: no implementation commits — working tree clean for `packages/agent-framework/src/command-api/provider/` and `packages/agent-cli/src/cli.ts`; latest commit on provider-factory/provider-merge is CLI-064 (#698, 847cf8991), which introduced `ProviderConfigError` as a dependency of this item, not CLI-066 work.

### [GATE-IMPLEMENT] — ✅ PASS | 2026-06-12

**Status upgrade:** approved → in-progress

- Tasks file created: `.agents/tasks/CLI-066.md` exists with tasks T1–T8 and a Test Plan summary deferring to this spec's authoritative TC table.
- Tasks file path recorded: `## Tasks` section lists `.agents/tasks/CLI-066.md` (T1~T8, TC-01~TC-07 매핑).
- Tasks correspond to Completion Criteria (one task per TC-N): T1↔TC-01 (env-default synthesis, `source: 'env-default'`, `$ENV:` key reference); T2↔TC-02 (`ANTHROPIC_API_KEY` + `GEMINI_API_KEY`, anthropic wins by definition order — matches the reworded TC-02); T3↔TC-03 (settings profile wins); T4↔TC-04 (`ProviderConfigError` "No provider configuration found" unchanged); T5↔TC-05 (gemma literal-apiKey and openai no-default-model excluded; qwen/deepseek synthesize from complete defaults incl. baseURL — matches the reworded TC-05); T6↔TC-06 (one-line stderr notice, never the key value); T7↔TC-07 (framework + CLI SPEC resolution order); T8 is an additional verification/PR task beyond the TC minimum.
- Prior FAIL (2026-06-12) resolution verified: the spec's Solution correction note was checked against `packages/agent-provider/src/*/` source — openai `defaults` contains only `apiKey: '$ENV:OPENAI_API_KEY'` with no `model` (modelCatalog `status: 'unavailable'`, `openai/provider-definition.ts:30-37`); gemma `defaults.apiKey` is the literal `'lm-studio'` (not an `$ENV:` reference); qwen and deepseek both carry `$ENV:` apiKey reference + model + baseURL in `defaults` (`qwen/provider-definition.ts:77-81`, `deepseek/provider-definition.ts:43-47`); anthropic and gemini carry `$ENV:` apiKey + model; definition order in `default-provider-definitions.ts` is anthropic → openai → gemini → gemma → qwen → deepseek, so anthropic precedes gemini as TC-02/T2 assume. T2/T5 no longer contradict TC-02/TC-05 — both sides now state the same corrected membership.
- Approved Decision integrity: the candidate rule in Solution step 1 and the Decision (definition-defaults fallback, settings-first, no persistence, startup notice) are unchanged; only the draft's expected membership list was corrected via the documented italic correction note, with TC-02/TC-05 carrying inline rationale.
- NON-COMPLIANCE trigger check: no implementation commits — `git status` clean for `packages/agent-framework/src` and `packages/agent-cli/src`; latest commits touching the affected paths are CLI-065 (#699, f25ad91b5), CLI-064 (#698, 847cf8991), CLI-063 (#697, eedc2f9bc) — all prior items, no CLI-066 work started.

### [GATE-VERIFY] — ❌ FAIL | 2026-06-12

**Status remains:** in-progress
**Failed criteria:**

- All tasks complete: T7 (TC-07 SPEC sync) is marked `[x]` but its substance is materially incorrect — `packages/agent-framework/docs/SPEC.md` §Provider Resolution Order (line 362) states the synthesized config's "key stays the `$ENV:` reference", which is the **pre-correction draft behavior**. The documented in-Decision TC-01 correction (resolved key for profile-path parity, env var NAME in the dedicated `sourceEnvVar` field) was applied to the spec document, the implementation (`resolveEnvDefaultProvider` returns `apiKey: envValue` + `sourceEnvVar`, provider-factory.ts), and the tests (TC-01 asserts `apiKey: 'sk-test'`, `sourceEnvVar: 'ANTHROPIC_API_KEY'`) — but NOT to the framework SPEC.md, which also never mentions `sourceEnvVar`. The SPEC (SSOT) now contradicts the shipped behavior on the exact point the correction addressed. CLI SPEC.md §Zero-Config Startup has no such contradiction.
  **Required action:** Update `packages/agent-framework/docs/SPEC.md` §Provider Resolution Order to match the corrected TC-01 behavior (resolved key — profile-path parity via `normalizeProviderConfig`; env var name carried in `sourceEnvVar`; notice never touches the key value), then re-run GATE-VERIFY.

All other criteria verified and passing (no re-verification needed beyond the SPEC fix):

- Tasks T1–T6 `[x]`; T8 (wrap-up) unchecked but every component independently verified per the CLI-063/064/065 GATE-VERIFY interpretation: PR #700 OPEN (`feat/cli-066-env-zero-config` → `develop`, "feat(framework,cli): env-var-only zero-config startup (CLI-066)") with build SUCCESS + quality SUCCESS (Cloudflare Pages failure is the known non-blocking docs-preview check); backlog evidence recorded in `.agents/backlog/completed/CLI-066-env-key-only-startup-rejected.md` (status: done).
- Build passes: `pnpm --filter` build for agent-framework, agent-cli, agent-command, agent-core — all "Build complete".
- Tests pass: named files fresh-run — `env-default-provider.test.ts` 10/10 (TC-01 ×2 incl. resolved key + sourceEnvVar, TC-02 ×2 definition order, TC-03 profile-wins, TC-04 ProviderConfigError, TC-05 ×3 exclusions, empty-env guard), `cli-exit-codes.test.ts` 3/3 incl. TC-06 (notice exactly once, no key value). Full suites: agent-framework 901/901, agent-cli 128/128, agent-command 168/168, agent-core 705/705. `pnpm typecheck` 0 errors; `pnpm lint` 0 errors (643 warnings).
- Implementation matches the approved Decision: settings-first (env-default consulted only after `resolveActiveProvider` returns nothing), definition-order priority, no persistence, injected env (`IReadProviderSettingsOptions.env` / `IEnsureProviderConfigOptions.env`, default `process.env`), typed `source: 'env-default'` + `sourceEnvVar` on `IProviderConfig` (agent-core SSOT), `ensureProviderConfig` early-returns only when `ctx.provider === undefined` and a candidate exists, CLI notice once via stderr (print) / terminal (TUI) naming provider/model/env-var — never the key value.
- In-Decision corrections within bounds: (1) synthesizable membership (anthropic/gemini/qwen/deepseek in; openai out — no default model; gemma out — literal key) already validated against `packages/agent-provider/src/*/` by the GATE-IMPLEMENT re-run; candidate rule itself unchanged. (2) TC-01 resolved-key correction is consistent with the Decision (which mandates env injection and a value-free notice, not a literal-reference key) and is correctly reflected in code + tests + spec doc — only the framework SPEC.md sync (the failed criterion above) lags.

- Previously failed criterion (T7 SPEC sync) re-verified directly: `packages/agent-framework/docs/SPEC.md` §Provider Resolution Order (lines 351–371) now states the corrected TC-01 behavior — (a) the key is **resolved** from the env map with profile-path parity explicitly noted (`resolveActiveProvider` also returns resolved keys via `normalizeProviderConfig`), (b) the env var NAME travels in the dedicated `sourceEnvVar` field, (c) `defaults.baseURL`/`timeout`/`options` are carried over, (d) the caller-notice sentence reads `sourceEnvVar` to name provider/model/env-var "never the key value". `grep` confirms zero remaining occurrences of the pre-correction wording ("stays the `$ENV:` reference") and 2 occurrences of `sourceEnvVar` in the file. The SPEC (SSOT) no longer contradicts the shipped behavior; resolution order settings → env-default → `ProviderConfigError` unchanged.
- All tasks complete: `.agents/tasks/CLI-066.md` T1–T7 `[x]`; T7's substance defect is resolved per the line above. T1's task label retains the draft wording ("key stays a `$ENV:` reference") but the tasks file explicitly defers to this spec's authoritative TC table, where TC-01 carries the documented correction — non-blocking plan-artifact wording, not SSOT. T8 (wrap-up) unchecked but every component independently verified per the established CLI-063/064/065 GATE-VERIFY interpretation, re-confirmed by the prior run: PR #700 OPEN with build=pass + quality=pass on the final commit; backlog evidence recorded in `.agents/backlog/completed/CLI-066-env-key-only-startup-rejected.md`.
- No tasks blocked or pending: tasks file contains no blocked markers; only T8 wrap-up remains open as adjudicated above.
- Build passes: per prior run's recorded evidence (agent-framework, agent-cli, agent-command, agent-core — all "Build complete"); the only change since that run is the markdown-only SPEC.md fix, which cannot affect build output.
- Tests pass: per prior run's recorded evidence — named tests `env-default-provider.test.ts` 10/10 + `cli-exit-codes.test.ts` 3/3; full suites agent-core 705/705, agent-framework 901/901, agent-command 168/168, agent-cli (with transports) 463 + 128/128; `pnpm typecheck` 0 errors, `pnpm lint` 0 errors. Markdown-only change since that run does not invalidate this evidence.
- Note for wrap-up (non-blocking for this gate): the SPEC.md fix is currently an uncommitted working-tree change on `feat/cli-066-env-zero-config` (`git status`: ` M packages/agent-framework/docs/SPEC.md`); it must be committed and pushed to PR #700 before merge so the SSOT correction lands with the feature.

### [GATE-COMPLETE: TC-01] — ✅ verified | 2026-06-12

- Command: `npx vitest run src/command-api/provider/__tests__/env-default-provider.test.ts` (cwd `packages/agent-framework`), fresh run this gate.
- Output: `Test Files 1 passed (1) / Tests 10 passed (10)`, exit 0 — includes `resolveEnvDefaultProvider (CLI-066) > TC-01: synthesizes the anthropic config from definition defaults when its env key is set` and `readProviderSettings env-default integration (CLI-066) > TC-01: no settings anywhere + env key set → env-default config` (resolved key + `sourceEnvVar`, per the documented in-Decision correction).
- Test reference recorded in Test Plan row TC-01.

### [GATE-COMPLETE: TC-02] — ✅ verified | 2026-06-12

- Command: same fresh `env-default-provider.test.ts` run (10/10, exit 0).
- Output: `TC-02: definition order decides when multiple synthesizable keys are set` and `TC-02: falls through to the next synthesizable definition when the first key is unset` both pass — anthropic wins by definition order over gemini (reworded TC-02).
- Test reference recorded in Test Plan row TC-02.

### [GATE-COMPLETE: TC-03] — ✅ verified | 2026-06-12

- Command: same fresh `env-default-provider.test.ts` run (10/10, exit 0).
- Output: `readProviderSettings env-default integration (CLI-066) > TC-03: settings profile wins over the env key` passes (regression held). Corroborated by user-execution evidence in `.agents/backlog/completed/CLI-066-env-key-only-startup-rejected.md` (status: done): profile + env key → profile wins with zero notice lines.
- Test reference recorded in Test Plan row TC-03.

### [GATE-COMPLETE: TC-04] — ✅ verified | 2026-06-12

- Command: same fresh `env-default-provider.test.ts` run (10/10, exit 0).
- Output: `TC-04: no profile + no recognized env key → ProviderConfigError unchanged` passes (regression held).
- Test reference recorded in Test Plan row TC-04.

### [GATE-COMPLETE: TC-05] — ✅ verified | 2026-06-12

- Command: same fresh `env-default-provider.test.ts` run (10/10, exit 0).
- Output: all three TC-05 cases pass — `openai (no default model) never synthesizes even with its env var set`, `gemma (literal non-$ENV apiKey) never synthesizes`, `deepseek synthesizes from its complete defaults including baseURL` (reworded TC-05 membership: anthropic/gemini/qwen/deepseek in; openai/gemma out).
- Test reference recorded in Test Plan row TC-05.

### [GATE-COMPLETE: TC-06] — ✅ verified | 2026-06-12

- Command: `npx vitest run src/__tests__/cli-exit-codes.test.ts` (cwd `packages/agent-cli`), fresh run this gate.
- Output: `Test Files 1 passed (1) / Tests 3 passed (3)`, exit 0 — includes `TC-06 (CLI-066): env-default startup runs print mode and prints the notice exactly once`, which counts occurrences of `Using fakezero (fake-zero-model) via FAKE_ZERO_CONF_KEY` on stderr (exactly 1) and asserts the key value is absent. Corroborated by real-binary user-execution evidence (backlog file above): real `ANTHROPIC_API_KEY`, no profile → exit 0, one notice `Using anthropic (claude-sonnet-4-6) via ANTHROPIC_API_KEY …`, no key leakage.
- Test reference recorded in Test Plan row TC-06.

### [GATE-COMPLETE: TC-07] — ✅ verified | 2026-06-12

- Action: direct read of both SPEC sections this gate (manual per Test Plan — doc content not automatable; skip reason recorded in Test Plan row TC-07).
- `packages/agent-framework/docs/SPEC.md` §Provider Resolution Order (lines 351–371): documents settings → env-default → `ProviderConfigError` with the corrected resolved-key behavior (profile-path parity via `normalizeProviderConfig`, env var NAME in dedicated `sourceEnvVar` field, notice never touches the key value, nothing persisted, injectable `env`).
- `packages/agent-framework/docs/SPEC.md` §Error Taxonomy: `ProviderConfigError` row reads "No settings profile and no env-default synthesis candidate (see §Provider Resolution Order)" — error meaning updated as specified.
- `packages/agent-cli/docs/SPEC.md` §Zero-Config Startup (env-default) (line 1013): documents the synthesized startup, exactly-one notice line (`Using <provider> (<model>) via <ENV_NAME> — run robota --configure to persist a profile.`) to stderr in print mode / terminal in TUI, key value never printed, settings profiles always win, and the new meaning of "No provider configuration found" (no profile AND no synthesizable env key).

### [GATE-COMPLETE] — ✅ PASS | 2026-06-12

**Status upgrade:** verifying → done

- All 7 Completion Criteria checkboxes TC-01..TC-07 verified and checked `[x]` this gate (per-TC evidence entries above with commands, outputs, and exit codes).
- Test Plan: all 7 rows now carry a test reference (TC-01..TC-06, file + describe/test names) or an explicit skip reason (TC-07 manual — verified directly by guard read); no TC-N silently unaddressed.
- Fresh test evidence: `env-default-provider.test.ts` 10/10 (exit 0) and `cli-exit-codes.test.ts` 3/3 (exit 0), both re-run at this gate on `feat/cli-066-env-zero-config`.
- Prior-gate evidence chain intact: GATE-WRITE ✅ → GATE-APPROVAL ✅ → GATE-IMPLEMENT ✅ (after one FAIL+fix) → GATE-VERIFY ✅ (after one FAIL+fix) — no gate bypassed.
- Tasks file archived: `.agents/tasks/CLI-066.md` → `.agents/tasks/completed/CLI-066.md` with T1–T8 all `[x]` (T8 substance — PR #700 build=pass quality=pass + backlog evidence file status done — verified at GATE-VERIFY; checked at archive per CLI-065 precedent). `## Tasks` section updated to the archived path.
- User-execution evidence on real binary recorded in `.agents/backlog/completed/CLI-066-env-key-only-startup-rejected.md` (status: done) — done-gate rule satisfied.
- Handoff note (outside this guard's scope): the framework SPEC.md fix and this spec document's gate updates are uncommitted working-tree changes on `feat/cli-066-env-zero-config`; they must be committed and pushed to PR #700 before merge. Moving this spec document `active/ → done/` is `backlog-pipeline`'s responsibility.
