feat(dev-portal): kbagent Developer Portal support with no-bypass write safety

[matyas-jirat-keboola]

Summary

Adds a kbagent dev-portal command group wrapping the Keboola Developer Portal API (apps-api.keboola.com). Production-safe by design: every write requires a human at a real terminal to type a random hex code — there is no --yes flag, no env-var override, and non-TTY shells exit 6 immediately.

• Multi-identity credential storage — service-account and admin identities live in config.json alongside KB project tokens (0600, _warning header extended to mention DP credentials). MFA codes prompted on /dev/tty for personal accounts; service accounts (service.{vendor}.{id}) skip MFA.
• v1 ops: identity CRUD (add/list/remove/edit/use/current/verify), reads (list, get) — fully agent-friendly for peer-config research, and writes (create, patch, upload-icon, publish, deprecate) — gated by random-code confirm + --dry-run preview path.
• Refactor: require_random_code_confirmation() extracted from commands/permissions.py into commands/_helpers.py so the same primitive backs permissions set/reset and every dev-portal write.
• Permission registry: 15 new dev-portal.* operations (--deny-writes blocks all writes automatically; deprecate is destructive, publish is admin).

Version bumped to 0.48.0. All rule #17 silent-drift surfaces updated (AGENT_CONTEXT, CLAUDE.md, SKILL.md, commands-reference.md, gotchas.md, new dev-portal-workflow.md).

are advisory; the human author retains every veto. CI-coverable issues
(lint, format, tests) are confirmed via make check, not duplicated here.

Summary

This PR adds a kbagent dev-portal command group wrapping the Keboola Developer Portal API (apps-api.keboola.com). The implementation is well-structured: the 3-layer architecture is respected (new DeveloperPortalClient extends BaseHttpClient; service layer is pure; commands are thin), the OPERATION_REGISTRY has all 15 real entries, the TTY-only write-safety design is sound, the require_random_code_confirmation() refactor is clean, and most silent-drift surfaces (AGENT_CONTEXT, CLAUDE.md, SKILL.md, commands-reference.md, gotchas.md) are correctly updated. However, three BLOCKING gaps remain: keboola-expert.md was not updated at all (the highest-risk silent-drift surface per CONTRIBUTING.md), the server/routers/dev_portal.py endpoint is absent without a documented skip justification, and the hints/definitions/dev_portal.py entry is absent without a documented exception. The verdict is REQUEST CHANGES.

Blocking findings

[B-1] plugins/kbagent/agents/keboola-expert.md — NOT updated (highest silent-drift risk)

keboola-expert.md does not appear in the PR's changed-files list and has zero mentions of dev-portal. Per CONTRIBUTING.md > "Plugin synchronization map", this file is the highest silent-drift risk in the repo and must be updated for any new write or destructive command. Two sub-gaps:

(a) §2 Tool Selection Matrix — none of the five write commands (dev-portal create, patch, upload-icon, publish, deprecate) have a | ... | First choice | Fallback | NEVER | row. Without a matrix entry, the keboola-expert subagent will fall back to MCP tool call or refuse portal write tasks instead of using the correct CLI path with --dry-run discipline.

(b) §1 Rule 6 VERSION GATE — the gate list ends with semantic-layer search-context|get-context ... = 0.47.0+ but never mentions dev-portal commands needing 0.48.0+. Any session running on a pre-0.48.0 install will attempt kbagent dev-portal ..., receive "command not found", and generate an unhelpful error traceback rather than the clean refusal the VERSION GATE is designed to produce.

Fix: add dev-portal {list,get,create,patch,upload-icon,publish,deprecate} and identity lifecycle need 0.48.0+ to the Rule 6 list, and add at minimum one Tool Selection Matrix row for dev-portal patch and one for dev-portal publish (the two highest-risk write paths), following the existing row format (| User intent | First choice | Fallback | NEVER |).

[B-2] src/keboola_agent_cli/server/routers/ — no dev_portal.py router, no documented skip

CONTRIBUTING.md > "HTTP API endpoint" checklist item states: "every command in a group has a matching endpoint in that group's router... Skip allowed only for genuinely terminal-only commands (interactive prompts, Rich-rendered output that has no useful JSON shape, doctor/init/update-style infrastructure). Document any skip in the PR description." The PR description does not mention this skip at all.

The dev-portal write commands (create, patch, publish, deprecate, upload-icon) use require_random_code_confirmation() which immediately exits 6 on a non-TTY — making them technically non-callable via REST. That design choice IS a valid justification for skipping the router. But the justification must appear in the PR description so reviewers do not re-file it, and so the decision is documented before it goes to main. The kbagent serve consumer contract (CONTRIBUTING.md Plugin sync map: "callers get HTTP 404 instead of a visible skip") cannot be met without at least a stub router that returns 501 with a human-readable message for the write commands, or an explicit skip documented in the description.

Fix (two options): (a) add a server/routers/dev_portal.py stub that exposes the read commands (list, get) as REST endpoints, and returns HTTP 405 Method Not Allowed for write commands with an explanation body; OR (b) add a one-sentence skip justification to the PR description ("No REST router: dev-portal write commands are hardcoded to require a live TTY; the REST surface intentionally omits them") so reviewers and future contributors understand the decision.

[B-3] src/keboola_agent_cli/hints/definitions/ — no dev_portal.py hint definition, no documented exception

CONTRIBUTING.md > "Code changes" checklist item: "every command must support --hint client and --hint service code generation". The exception list is explicit: doctor, context, init, serve, version, update, changelog, permissions, and the four http self-call verbs. dev-portal is NOT on that list — it wraps apps-api.keboola.com via DeveloperPortalClient, which IS a Keboola API client (same pattern as KeboolaClient, ManageClient, AiServiceClient).

The PR description does not mention --hint at all, and grep 'should_hint\|emit_hint' dev_portal.py returns empty.

Fix: add hints/definitions/dev_portal.py with CommandHint entries for at minimum dev-portal list, dev-portal get, and dev-portal patch (the three most likely to be used programmatically via the REST surface or --hint service code generation). The write-commands' --hint client recipes are still useful for scaffolding scripts that wrap the client directly. If the team decides dev-portal is deliberately --hint-free (e.g., because the portal API is credential-gated and hint generation is not useful without live creds), document that decision in the PR description with the same one-sentence justification format the checklist uses.

Non-blocking findings

[NB-1] tests/test_e2e.py:TestDevPortalE2E — only one unconditional E2E test; 13 of 15 commands have zero E2E coverage

CONTRIBUTING.md convention #16 (also CONTRIBUTING.md > "Tests" checklist): "Every new CLI command MUST have a corresponding E2E test in tests/test_e2e.py." The PR adds TestDevPortalE2E with two tests: test_identity_list_smoke (unconditional, confirms the command returns a list from an empty config — no network, no portal) and test_list_apps_against_real_portal (skip-guarded behind E2E_DP_USERNAME / E2E_DP_PASSWORD). The PR description marks the credential-gated test as "Optional".

The unconditional smoke test exercises dev-portal identity list only. The 12 other commands (dev-portal get, create, patch, upload-icon, publish, deprecate, identity add, identity remove, identity edit, identity use, identity current, identity verify) have no E2E test at all, even at the exit-code-only level. This is understandable for writes (TTY requirement makes them hard to E2E-test in CI), but reads (dev-portal list --vendor, dev-portal get --app) can be exercised against a public vendor endpoint without private credentials.

Deferring portal writes to a follow-up cycle is acceptable given the TTY constraint. However, dev-portal list and dev-portal get (which do NOT require write credentials) should have at least a skip-guarded test parallel to how other credential-gated E2E tests work in this repo.

[NB-2] src/keboola_agent_cli/commands/permissions.py:246,293 — permissions set/reset refactor drops structured error in JSON mode for the non-TTY path

The old _require_interactive_confirmation() returned False on non-TTY, and both permissions_set and permissions_reset called formatter.error(message="Confirmation failed. Permission policy not changed.", error_code=ErrorCode.PERMISSION_DENIED) before raising typer.Exit(code=EXIT_PERMISSION_DENIED).

The new require_random_code_confirmation() writes directly to sys.stderr and raises typer.Exit(code=EXIT_PERMISSION_DENIED) — bypassing formatter.error() entirely. In --json mode, callers that previously received a structured {"status": "error", "error": {"code": "PERMISSION_DENIED", "message": "Confirmation failed. ..."} envelope now receive only an empty body and exit code 6. This is a backward-compatibility regression for any script that was parsing the JSON error envelope on exit-code-6 from permissions set/reset.

The test_set_rejected_without_confirmation test only asserts result.exit_code == EXIT_PERMISSION_DENIED and does not catch this regression.

Fix: in the new require_random_code_confirmation(), write the error to sys.stderr for human-mode consistency, but also raise a KeboolaApiError(error_code=ErrorCode.PERMISSION_DENIED, message="...") that the calling command can catch and route through formatter.error() — or keep require_random_code_confirmation() raising typer.Exit and have the command wrap the call in a try/except to emit the structured error first.

[NB-3] src/keboola_agent_cli/changelog.py:0.48.0 — changelog lists dev-portal.identity.get which is not a registered operation or an implemented command

The 0.48.0 changelog entry reads: "15 dev-portal.* permission-registry operations (...dev-portal.identity.verify, dev-portal.identity.get) registered...". The command dev-portal identity get does not exist in dev_portal.py (no @identity_app.command("get") decorator), and "dev-portal.identity.get" is not in OPERATION_REGISTRY. The actual 15th entry is "dev-portal.identity" (parent callback placeholder, categorized as read).

This is a documentation-only inaccuracy — the OPERATION_REGISTRY itself is correct. But the changelog is a user-facing release document; shipping it with a non-existent operation listed as if it were real will confuse anyone who reads the release notes and tries to use kbagent dev-portal identity get.

Fix: replace dev-portal.identity.get in the changelog text with dev-portal.identity (the parent callback entry that actually exists), and drop the phantom command reference.

Nits

• [NIT-1] src/keboola_agent_cli/commands/dev_portal.py:260 and src/keboola_agent_cli/commands/_helpers.py:require_random_code_confirmation — _assert_tty() and require_random_code_confirmation() both check sys.stdin.isatty(). The write commands call _assert_tty() early (before API calls), then call require_random_code_confirmation() later (after the preview). This double-check is intentional for UX (fail fast before API calls), but both functions have identical TTY-check logic. Consider extracting _is_tty() -> bool into _helpers.py as the single source of truth for the TTY predicate, so the two guards cannot diverge.

• [NIT-2] src/keboola_agent_cli/permissions.py:153 — "dev-portal.identity.remove": "write" but "data-app.secrets-remove": "destructive" (analogous credential-remove operation). Credential removal is arguably destructive by the CONTRIBUTING.md table ("Destroys data") since it permanently deletes the stored identity. This is a judgment call — the existing precedent in "project.remove" is "admin" — but aligning with data-app.secrets-remove: destructive would be more consistent.

Open questions for the author

1. --hint exception decision: Is dev-portal intentionally excluded from --hint support? The exception list in CONTRIBUTING.md is for "commands that manage kbagent itself, not Keboola". The Developer Portal is a separate Keboola service — the same rationale as AiServiceClient. If the call patterns are genuinely too variable to hint (portal payloads are arbitrary JSON, not a fixed schema), that is worth documenting explicitly as a first-class exception in CONTRIBUTING.md for future contributors.

2. Server router skip scope: If the read commands (dev-portal list, dev-portal get) do not require TTY, could they be exposed as REST endpoints in server/routers/dev_portal.py even if write commands are skipped? The "peer-research" use case described in the workflow doc is plausible in a scheduled agent context (reading portal entries programmatically), which is exactly the use case kbagent serve is designed for.

Review of #354 — feat(dev-portal): kbagent Developer Portal support with no-bypass write safety

Generated by kbagent-pr-reviewer subagent. Verdict and findings below
are advisory; the human author retains every veto. CI-coverable issues
(lint, format, tests) are confirmed via make check, not duplicated here.

Summary

This PR adds a kbagent dev-portal command group wrapping apps-api.keboola.com with
15 new OPERATION_REGISTRY entries, full 3-layer architecture compliance, and a
no-bypass TTY confirm for all write operations. The implementation is solid: make check
passes with 3667 tests, 3-layer boundaries are respected, all new ErrorCode enum entries
are used properly, and backward-compat on AppConfig is maintained via safe defaults.
gotchas.md correctly uses (since v0.48.0) in the heading.

Two silent-drift gaps prevent a clean APPROVE: (1) plugins/kbagent/agents/keboola-expert.md
was NOT updated despite the PR description claiming "all rule #17 surfaces updated" — the
§2 Tool Selection Matrix has no rows for any of the five write/destructive dev-portal
commands; (2) hints/definitions/dev_portal.py is absent with no documented skip reason,
which CONTRIBUTING.md requires for every command wrapping a non-infrastructure API client.
Additionally, dev-portal list and dev-portal get are pure reads with no TTY dependency
and have no server router endpoint, undocumented in the PR description.

Blocking findings

[B-1] plugins/kbagent/agents/keboola-expert.md — §2 Tool Selection Matrix missing all dev-portal rows

git diff origin/main...origin/feat/dev-portal -- plugins/kbagent/agents/keboola-expert.md
produces zero output: the file was not changed in this PR. The PR description claims
"All rule #17 silent-drift surfaces updated" but keboola-expert.md is not in the
changed-files list. CONTRIBUTING.md §"Plugin synchronization map" and §"Releasing a new
version" step 5 both require a | intent | First choice | Fallback | NEVER | row for
every new write/destructive command. Five commands qualify: dev-portal create (write),
dev-portal patch (write), dev-portal upload-icon (write), dev-portal publish (admin),
dev-portal deprecate (destructive). Without these rows, the keboola-expert subagent
will fall back to MCP tool call or refuse tasks involving Developer Portal updates, defeating
the purpose of the agent-safe --dry-run preview path.

Fix: add rows to the §2 matrix for each of the five write/destructive commands and for the
read commands (dev-portal list, dev-portal get) to enable peer-config research workflows.
For the write rows, the "First choice" should be kbagent dev-portal <cmd> --dry-run (show
preview to human, then human runs without --dry-run); "NEVER" should call out bypassing the
TTY confirm or passing --yes (which does not exist). Also update §1 Rule 6 VERSION GATE
examples if 0.48.0 adds a minimum-version constraint worth noting.

[B-2] src/keboola_agent_cli/hints/definitions/ — no dev_portal.py hint file, no documented skip

CONTRIBUTING.md "Checklist: Adding a New CLI Command" requires every command wrapping a
Keboola API client to have a CommandHint with ClientCall + ServiceCall in
hints/definitions/. The listed infrastructure exception (doctor, context, init, serve,
version, update, changelog, permissions, http) does NOT apply here: DeveloperPortalClient
inherits BaseHttpClient and is a standard HTTP client for an external Keboola service,
exactly the pattern hints are designed for. src/keboola_agent_cli/hints/definitions/__init__.py
has no dev_portal import. The PR description does not mention a skip reason.

Fix: add src/keboola_agent_cli/hints/definitions/dev_portal.py with CommandHint
registrations for the read commands (dev-portal.list, dev-portal.get) and the identity
CRUD commands. Write commands can include a hint with a note that actual execution requires
a real terminal. Add from . import dev_portal to hints/definitions/__init__.py. Then add
if should_hint(ctx): emit_hint(...) short-circuits in each command function.

[B-3] src/keboola_agent_cli/server/routers/ — no router for dev-portal read commands; skip undocumented

CONTRIBUTING.md requires a 1:1 server router for every new command group, with a skip
allowed "only for genuinely terminal-only commands." The write commands (create, patch,
upload-icon, publish, deprecate) are legitimately terminal-only because they call
require_random_code_confirmation() unconditionally (defensible skip). But dev-portal list
and dev-portal get are pure reads: they return structured JSON, have no TTY dependency,
and are directly useful for programmatic consumers such as Web UI panels, scheduled agents,
and CI pipelines that need to inspect portal state. The PR description contains zero
mention of the router skip, leaving reviewers unable to assess whether it was intentional.

Fix: add src/keboola_agent_cli/server/routers/dev_portal.py with at minimum
GET /dev-portal/list and GET /dev-portal/get endpoints, mirroring the CLI flag shapes.
For the five write commands, document the skip in the PR description: "dev-portal write
commands are intentionally absent from the REST router — they require a human at a TTY and
cannot be safely invoked programmatically."

Extra finding (human review): double login / double MFA on patch and publish

Spotted during manual review on top of the automated pass — not flagged by the bot.

patch and publish open a Developer Portal client twice in two separate with blocks, each triggering a fresh _ensure_authenticated() → a fresh /auth/login:

• prepare_patch logs in to fetch current state — services/dev_portal_service.py:182
• apply logs in again to send the write — services/dev_portal_service.py:255
• (same shape for publish: prepare_publish at services/dev_portal_service.py:234 + apply at :255)

Impact:

• Service accounts (service.{vendor}.{id}, no MFA): just a redundant second login round-trip — harmless but wasteful.
• Personal admin accounts: two MFA prompts for a single patch/publish — once in prepare_*, then the random-code confirm, then a second MFA prompt in apply. That's a rough UX for the human-in-the-loop flow this group is built around.

create/deprecate/upload-icon are fine — their prepare_* defers login, so apply logs in once.

Suggested fix: reuse a single authenticated client (or cache the bearer) across prepare_* → apply for one invocation, so the human authenticates at most once per command. The bearer already lives only in process memory, so threading the same client through is safe.

Everything else in the PR looks solid — clean 3-layer split, full test coverage, sound TTY-confirm safety model, token never logged/persisted beyond the 0600 config.

Hi @matyas-jirat-keboola — Petr asked me to push the review follow-ups straight onto this branch so it's unblocked. Three commits (bac250c, bfcd7f5, 46756a5), make check green (3673 passed, 0 failures). Holler if you'd rather I'd left any of these to you.

1. fix: authenticate once across prepare/apply (no double MFA) — bac250c
patch/publish opened a fresh client in prepare_* (to read current state) and again in apply() (to write), so each did its own /auth/login. On a personal MFA account that's two MFA prompts for one write. The service now caches the bearer per alias (in-memory, rebuilt per CLI call) and seeds it into the apply() client via a new client.seed_bearer()/bearer API. create/deprecate/upload-icon were already single-login. Regression test asserts exactly one login across prepare+apply.
Bonus: typed BaseHttpClient.__enter__ as Self, which clears pre-existing ty errors (16 of them) where DeveloperPortalClient methods were unresolved on BaseHttpClient inside with blocks — make typecheck is now clean on this branch.

2. feat: read endpoints via kbagent serve — bfcd7f5
New server/routers/dev_portal.py: GET /dev-portal/apps (list by vendor) + GET /dev-portal/apps/{app} (get one), wired into the app + ServiceRegistry. Mirrors dev-portal list|get for external consumers. Writes + identity management stay CLI-only by design (TTY-confirmed writes are meaningless over HTTP; identity commands handle credentials) — documented in the router docstring and OpenAPI tag.

3. docs: Tool Selection Matrix row — 46756a5
One per-group dev-portal row in keboola-expert.md §2. Stayed under the 60 KB prompt budget by trimming now-deprecated --hint client fallbacks from five existing rows (per #355, --hint is superseded by kbagent serve).

The matrix-row and --hint findings from the earlier review are resolved at the policy level by #355 (merged), so they're no longer blocking here.

Review of #354 — feat(dev-portal): kbagent Developer Portal support with no-bypass write safety

Generated by kbagent-pr-reviewer subagent. Verdict and findings below
are advisory; the human author retains every veto. CI-coverable issues
(lint, format, tests) are confirmed via make check, not duplicated here.

Summary

This PR adds a kbagent dev-portal command group wrapping apps-api.keboola.com. The architecture is sound: identity CRUD in config.json, prepare/apply split with a random-code TTY gate on writes, bearer cached in-process only. The earlier-flagged --hint and tool-matrix issues were resolved at the policy level (PR #355). Two new commits since the last review introduced the bearer-cache lifecycle (bac250c) and the serve read router (bfcd7f5). The bearer-cache fix is correct for the CLI (single-invocation service), but its interaction with the long-lived ServiceRegistry in kbagent serve introduces a stale-bearer lockout bug and an auth-bypass gap in --ui mode. Both are BLOCKING. Verdict: REQUEST CHANGES.

[B-1] src/keboola_agent_cli/server/app.py:721-748 — /dev-portal missing from api_prefixes in _is_ui_public; auth bypass in --ui mode

_is_ui_public returns True for any GET path not in api_prefixes. The tuple at lines 721-748 lists every other router prefix (/projects, /configs, /data-apps, ...) but omits /dev-portal. In kbagent serve --ui mode, BearerAuthMiddleware.dispatch calls is_ui_public(method, path) at auth.py:72; a GET /dev-portal/apps?vendor=keboola request does not match any prefix, so is_ui_public returns True and the request is forwarded to the router without bearer validation. The dev-portal router executes normally, returning real portal app data to an unauthenticated caller. Note: a browser user who loaded GET / already has the session cookie and is unaffected; this gap hits script/curl callers in --ui mode.

Fix: add "/dev-portal" to the api_prefixes tuple alongside the other router prefixes.

# app.py line ~748 — add this line:
"/dev-portal",

[B-2] src/keboola_agent_cli/services/dev_portal_service.py:160-164 — stale bearer never cleared on error in _authed_client; permanent 401 lockout in kbagent serve

_bearers[alias] = new_bearer is inside the with client: block after the yield. When an exception propagates out of yield (e.g., portal returns 401 on an expired bearer), Python's generator protocol causes the with to exit via GeneratorExit/exception path, skipping new_bearer = client.bearer and the _bearers update entirely. The stale bearer remains in self._bearers[alias]. In the CLI this is harmless (the service is rebuilt per invocation). In kbagent serve, ServiceRegistry is a singleton (app.state.registry installed once in create_app), so dev_portal._bearers persists across all HTTP requests. Once a portal bearer expires (Developer Portal tokens have a finite TTL), every subsequent GET /dev-portal/* call seeds the stale bearer, receives a new 401, and the service never re-authenticates — permanent lockout until server restart.

Fix: clear _bearers[alias] on INVALID_TOKEN / DP_LOGIN_FAILED errors, or use a try/except around the yield to remove the entry on error:

@contextmanager
def _authed_client(self, alias: str) -> Iterator[DeveloperPortalClient]:
    ident = self._resolve_identity(alias)
    client = self._client_factory(ident)
    cached = self._bearers.get(alias)
    if cached is not None:
        client.seed_bearer(cached)
    try:
        with client:
            yield client
            new_bearer = client.bearer
            if new_bearer is not None:
                self._bearers[alias] = new_bearer
    except KeboolaApiError as exc:
        if exc.error_code in (ErrorCode.INVALID_TOKEN, ErrorCode.DP_LOGIN_FAILED):
            self._bearers.pop(alias, None)
        raise

A regression test should verify that after a simulated 401 from the portal, a second call re-authenticates (login count increases to 2 instead of staying at 1).

Non-blocking findings

[NB-1] plugins/kbagent/agents/keboola-expert.md:65-114 — dev-portal group not listed in §1 Rule 6 VERSION GATE

The dev-portal command group requires 0.48.0+, but §1 Rule 6 does not mention it. The tool-selection matrix row (§2, line 166) does contain (0.48.0+) inline, so a careful agent will encounter it during task planning — but the VERSION GATE is the canonical "check first" mechanism. An agent on 0.47.x might proceed to dev-portal list and get a confusing "No such command" error instead of a clean refusal.

Fix: add \dev-portal` command group needs 0.48.0+to the VERSION GATE examples list alongside the other version entries, e.g. after thesemantic-layer` block.

[NB-2] src/keboola_agent_cli/services/dev_portal_service.py:198-219 and src/keboola_agent_cli/commands/dev_portal.py:383-412 — patch --dry-run performs a live portal GET (undocumented portal connectivity requirement)

prepare_patch calls _authed_client → logs in → calls client.get_app() to fetch current state for diff computation. This is correct behaviour (the dry-run diff would be empty without it), but --dry-run is documented as the "agent-safe preview" path. An AI agent running kbagent dev-portal patch --dry-run against an identity with a personal account (MFA required) will trigger the MFA /dev/tty prompt, which has no TTY in a non-interactive context and will raise DP_MFA_REQUIRED. The test at tests/test_dev_portal_cli.py:140 mocks prepare_patch entirely, hiding this dependency.

Fix: document the connectivity requirement in --dry-run's help text and in dev-portal-workflow.md, or add a service-account-only note. Optionally, add a CLI test that exercises the DP_MFA_REQUIRED error path for patch --dry-run with a personal account on a non-TTY (using _tty_prompt monkeypatch returning None).

Nits

• [NIT-1] src/keboola_agent_cli/commands/dev_portal.py:287 — _render_pending type annotation is # type: ignore[type-arg]; the function signature could use PendingWrite from the service module instead of the untyped Any workaround now that all Pending* types are exported.
• [NIT-2] src/keboola_agent_cli/commands/dev_portal.py:324 — _pending_as_json also carries # type: ignore[type-arg]; same fix as NIT-1 applies.

• Behavior reproduction: could not exercise against a real Developer Portal (no E2E_DP_USERNAME/E2E_DP_PASSWORD). CLI unit tests pass; serve router tests pass. The two BLOCKING findings are structural and do not require live portal verification.

Open questions for the author

• Is patch --dry-run intentionally agent-callable against service accounts only (personal accounts would MFA-block)? If yes, the workflow doc should say so explicitly. If personal accounts should be supported for dry-run, the prepare layer needs to handle the no-TTY case gracefully (return a diff stub or skip the get_app call).

Thanks for the re-review — both BLOCKING findings were real regressions from my earlier follow-up commits. All six findings addressed in 583708f, b3f60d3, e6b787c; make check green (3675 passed, 0 failures, ty clean).

[B-1] auth bypass on GET /dev-portal/* in --ui mode — fixed 583708f
Added "/dev-portal" to api_prefixes in _is_ui_public (app.py). New test test_dev_portal_read_requires_auth_in_ui_mode asserts 401 without auth.

[B-2] stale bearer permanent lockout in serve — fixed b3f60d3
_authed_client now evicts _bearers[alias] on INVALID_TOKEN/DP_LOGIN_FAILED, so the next call re-authenticates instead of replaying the dead token. Regression test seeds a stale bearer → asserts the 401 propagates AND the entry is evicted → a follow-up call logs in fresh and succeeds. (Went with eviction/next-call recovery rather than in-request retry on purpose: retry-on-401 would re-trigger an MFA prompt mid-apply on a personal account, which is exactly what the bearer cache was added to avoid.)

[NB-1] dev-portal missing from §1 VERSION GATE — fixed e6b787c
Added dev-portal command group = 0.48.0+ to the VERSION GATE list; stayed under the 60 KB prompt budget by trimming two now-deprecated --hint client prose mentions.

[NB-2] patch --dry-run does a live portal GET — fixed e6b787c
patch/publish --dry-run help text and dev-portal-workflow.md now state the preview still logs in + GETs the app (needs connectivity; a personal/MFA identity prompts for MFA), and recommend a service.{vendor}.{id} identity for a fully non-interactive preview.

[NIT-1/NIT-2] # type: ignore[type-arg] on _render_pending/_pending_as_json — fixed e6b787c
Both now annotate with OutputFormatter / PendingWrite (TYPE_CHECKING import) and drop the ignores.

Open question (your last point): patch --dry-run against a personal account WILL MFA-block — that's now documented as a service-account path rather than reworked, since the diff genuinely needs the current state. Happy to make the prepare layer return a diff stub for the no-TTY case instead if you'd prefer that over the doc note.
