+#
+# Triggers:
+#   - workflow_dispatch — manual run. The Actions UI branch picker selects the
+#     ref (github.ref), always a same-repo branch. We deliberately take NO
+#     free-form `ref` input: that would let a manual run check out arbitrary
+#     (e.g. external PR) code while the staging token is in the job env.
+#   - schedule (hourly) — exercises the `@beta` channel. `develop` is the default
+#     branch AND the beta release source, so a scheduled run checks it out and
+#     builds from source. The `gate` job skips the run unless the published
+#     `supabase@beta` version changed since the last green run (an actions/cache
+#     marker keyed on the version), so we only spend a staging project when there

+# Post-publish end-to-end verification that the *published* install channels
+# (Homebrew, Scoop, and the curl|bash install script) actually install the
+# just-released CLI and serve artifacts whose checksums match what the channel
+# manifests declare. Runs automatically after every brew/scoop publish (called
+# from release-shared.yml's `verify-install-channels` job) and can also be
+# dispatched manually against any already-published version when debugging an
+# install regression.
+#
+# Exists primarily to catch regressions like CLI v2.107.0, where the Homebrew
+# formula and Scoop manifest shipped sha256 checksums that did not match the
+# tarballs on the GitHub Release, so `brew install` / `scoop install` failed
+# for every user with "Formula reports different checksum". brew, scoop, and
+# the install script all verify the declared checksum against the downloaded
+# bytes before installing, so a real install reproduces that failure exactly
+# instead of trusting the manifest the publish step wrote.
+#
+# Each leg goes beyond `supabase --version` (handled by the Bun wrapper without
+# touching the sidecar) and runs `supabase completion bash`, a Go-proxied
+# command, so a package that omits or misplaces the colocated `supabase-go`
+# sidecar fails here instead of silently shipping broken proxied commands.

 The pre-recording cleanup deletes projects named `cli-e2e-test`, `my-project`, and `to-delete` so re-recording never hits a 409 name-conflict. Do not add tests that rely on pre-existing named projects existing on staging.
 
+## Live mode (ADR-0013)
+
+`live` is a third mode (`CLI_E2E_MODE=live`) that, unlike replay/record, **does not use the replay server**. The harness is wired straight at the real Management API (`CLI_E2E_API_URL`) and the real Docker socket; tests assert on **real outcomes**.
+
+- Live tests are `src/tests/live/**/*.live.e2e.test.ts`, run only via `vitest.live.config.ts` (the default config excludes them). They `skipIf(!isLive)`, so they are inert on the replay suite.
+- Global setup (`tests/live-setup.ts`) provisions **one ephemeral project per run** (`cli-e2e-live-{target}-{runId}-{short}`), waits for `ACTIVE_HEALTHY`, resolves the anon JWT, the IPv4 **session-pooler `dbUrl`** (for `--db-url` DB commands), the functions URL, and a seeded storage bucket, exposing them via `inject()`. It deletes the project on teardown (even on failure). Setup is intentionally **dumb** — no provisioning retry; the CI job re-runs the step on flake.
+- Use `testLive` from `src/tests/live/live-context.ts`: `run(cmd)` (direct-wired CLI), `invoke(slug)` (direct HTTP call sending the **anon JWT** in both `Authorization: Bearer` and `apikey`), plus `workspace` (a fresh `supabase init` config so golden paths exercise a generated config), `projectRef`, `anonKey`, `functionsUrl`, `dbUrl`, `storageBucket`. The functions deploy tests call `seedFunctions(workspace.path)` to layer the `deploy-e2e-*` fixtures + their `[functions.*]` config onto the init'd config.
+- **Assertion style:** outcome-based — assert `exitCode`/`stdout` substrings and the function's HTTP status + JSON body. This is ID-agnostic, so **no normalization/snapshots by default**. If the CLI's own diagnostic output is ever the assertion target, add a scoped normalizer for that one test — do not make normalization the default.
+- **Authoring target is `go`** (source of truth for the port); `ts-legacy` runs the same tests to prove the shim matches. Both run as separate CI jobs.
+- Retargeting to another env (e.g. `supabox`) is an env swap only: `CLI_E2E_TARGET_ENV` + `CLI_E2E_API_URL` + `CLI_E2E_PROJECT_HOST` + token. Tests assert on function output, not hostnames.
+- **CI triggers** (`.github/workflows/live-e2e.yml`): `workflow_dispatch` (manual; the Actions branch picker selects the ref — no free-form `ref` input, so the staging token never reaches arbitrary code) and an hourly `schedule`. There is **no `pull_request` trigger** — run it manually on a PR branch for pre-merge coverage. The scheduled run exercises the `@beta` channel: `develop` is the default branch and the beta release source, so it builds from `develop` source and runs the same `[go, ts-legacy]` matrix. A `gate` job skips the run unless the published `supabase@beta` version changed since the last green run (an `actions/cache` marker keyed on the version, written by `finalize` only after **both** legs pass), so a staging project is spent only when there is a new beta to test. Because the marker is written only on a fully-green matrix, a chronically-failing `@beta` keeps re-running every hour until it goes green or a newer beta supersedes it (intended — the failure stays visible).

 - `beta` → `--name supabase-beta` (a separate formula / manifest for the prerelease channel)
 - `alpha` → skipped (Homebrew + Scoop are not part of the v3 alpha story; npm only)
 
+### Post-publish: install-channel verification
+
+Once the channels are live, two reusable workflows run automatically (last in `release-shared.yml`, non-gating — by the time they run the artifacts are already published, so a failure surfaces as a red post-release signal rather than blocking distribution):
+
+- `[setup-cli-smoke-test.yml](../../../.github/workflows/setup-cli-smoke-test.yml)` (`setup-cli-smoke` job) — installs the released version through `supabase/setup-cli` (the GitHub Release download path) on Linux, macOS, Windows, and Alpine.
+- `[verify-install-channels.yml](../../../.github/workflows/verify-install-channels.yml)` (`verify-install-channels` job) — runs a **real** `brew install` (macOS **and** Linux, so both the `on_macos` and `on_linux` stanzas of the formula are exercised), `scoop install`, and `curl|bash` install of the **published** install script (fetched from the release asset, not the repo checkout) against the just-published Homebrew tap, Scoop bucket, and GitHub Release. Each leg then asserts `supabase --version` matches and runs `supabase completion bash` (a Go-proxied command) so a package that omits or misplaces the `supabase-go` sidecar fails too. brew, scoop, and the install script each verify the published `sha256`/`hash` against the downloaded tarball, so this is the signal that would have caught CLI v2.107.0 (where the brew/scoop manifests shipped checksums that did not match the release tarballs and every `brew install` / `scoop install` failed). It only runs for `beta`/`stable` (the channels that publish brew/scoop) and can be dispatched manually against any already-published version via the Actions tab.
+
 ### Verification
 
-After `release-shared.yml` finishes (all jobs including `publish-homebrew` and `publish-scoop`):
+The `verify-install-channels` workflow above automates the manual checks below for the brew/scoop/install-script channels; the steps remain useful for a manual sanity check or for the npm/provenance bits the workflow does not cover.

+- **`[remotes.*]` overrides are merged before push.** When a `[remotes.<name>]` block declares `project_id == <ref>`, `@supabase/config` merges that block's subtree over the base config at the raw (pre-decode) level — Go's `mergeRemoteConfig` (`apps/cli-go/pkg/config/config.go:550`) — so only the keys the block declares override the base. `Loading config override: [remotes.<name>]` prints to stderr. Two remotes sharing the target `project_id` abort with Go's `duplicate project_id for [remotes.<b>] and [remotes.<a>]` message.
 - KNOWN GAPS:
-  - **`[remotes.*]` overrides are not yet supported.** Faithful subset merging (Go's `mergeRemoteConfig`) requires a raw-TOML subtree merge; applying the decoded remote section verbatim would reset every non-overridden field to its schema default and silently corrupt the remote. Until the merge is implemented, `config push` **aborts with exit 1** (before any network call) when a `[remotes.<name>]` block declares `project_id == <ref>`, rather than pushing wrong values. Go-tested paths have no `[remotes.*]`.
   - **`encrypted:` (dotenvx) secret decryption is not reproduced.** The Go CLI decrypts `encrypted:` values before hashing and pushes the plaintext; we cannot decrypt here. Rather than push the ciphertext (which would overwrite the remote secret with garbage), `encrypted:` values are treated as unresolved — exactly like `env()` refs: they hash to `""`, so the empty hash gates them out of both the diff and the update body and the remote secret is left untouched.

 ## Output
 
 ### `--output-format text` (Go CLI compatible)
 
-Prints the schema diff in SQL migration format to stdout, or writes it to the file specified by `--file`.
-
-### `--output-format json`
-
-Not applicable.
+Progress to stderr (`Creating shadow database...`, `Diffing schemas[: <list>]`,
+`Finished supabase db diff on branch <branch>.`, drop-statement warning, and the
+`--file` write warning). The SQL diff prints to stdout when neither `--file` nor
+explicit `--output` is set.
 
-### `--output-format stream-json`
+### `--output-format json` / `stream-json`
 
-Not applicable.
+Progress strings still go to stderr; stdout carries a single structured envelope
+`{ diff, file, schemas, engine, dropStatements }` instead of the raw SQL.
 
-## Notes
+## Notes / Delegation
 
-- `--use-migra` (default true), `--use-pgadmin`, `--use-pg-schema`, `--use-pg-delta` are mutually exclusive differ strategies.
-- `--from` and `--to` enable explicit diff mode; both must be set together.
-- `--db-url`, `--linked`, and `--local` are mutually exclusive.
-- `--schema` / `-s` restricts diff to specific schemas.
+- `--use-migra` (default), `--use-pgadmin`, `--use-pg-schema`, `--use-pg-delta` are a
+  mutually-exclusive engine group; `--db-url` / `--linked` / `--local` are a
+  mutually-exclusive target group (default `--local`).
+- `--use-pgadmin` and `--use-pg-schema` rebuild the argv and exec the bundled Go
+  binary (their side effects are Go's); the Go child's telemetry is disabled so the
+  single `cli_command_executed` event comes from this TS command.
+- Explicit `--from`/`--to` mode always uses pg-delta and writes to `--output` (or stdout).

 ## Output
 
-### `--output-format text` (Go CLI compatible)
-
-Prints the pg_dump SQL output to stdout (or to the file specified by `--file`). Prints a confirmation message to stderr when `--file` is used.
-
-### `--output-format json`
-
-Not applicable.
-
-### `--output-format stream-json`
-
-Not applicable.
-
-## Notes
-
-- `--data-only` and `--role-only` are mutually exclusive.
-- `--use-copy` and `--exclude` require `--data-only`.
-- `--keep-comments` and `--data-only` are mutually exclusive.
-- `--db-url`, `--linked` (default true), and `--local` are mutually exclusive.
-- `--dry-run` prints the pg_dump command that would be executed without running it.
+SQL goes to **stdout** (or `--file`) in **all** `--output-format` modes — Go has
+no `--output-format` for `db dump`, so there is no machine envelope (same
+rationale as `test db`). Diagnostics go to **stderr**: `Dumping {schemas|data|
+roles} from {local|remote} database...`, the `--dry-run` notice, and the
+`Dumped schema to <abs>.` confirmation when `--file` is used. `--dry-run` prints
+the env-expanded script to stdout without running a container; with `--file` it
+still prints the `Dumped schema to <abs>.` confirmation (Go's PostRun fires on the
+successful dry-run) but does **not** create or truncate the file.
+
+On a linked dump whose container fails with an IPv6 connectivity error (no IPv4
+pooler retry available, or the retry also fails), the error is followed on stderr by
+the IPv4 transaction-pooler suggestion (Go's `SetConnectSuggestion`/`ipv6Suggestion`).
+
+> **Credential warning:** `--dry-run` expands the pg_dump script with live env
+> values, so the resolved `PGPASSWORD` (for a remote/linked project, the database
+> password) is printed **in cleartext** to stdout. This matches Go's `noExec`
+> (`internal/db/dump/dump.go`), but operators piping `--dry-run` output to logs or
+> CI artifacts should treat that output as a secret.
+
+## Notes / Divergences
+
+- `--data-only` XOR `--role-only`; `--keep-comments` XOR `--data-only`;
+  `--schema` XOR `--role-only`; `--db-url` XOR `--linked` XOR `--local`.
+  `--use-copy` / `--exclude` require `--data-only`. `--linked` defaults to true.
+- **Container-level pooler fallback is ported** (`RunWithPoolerFallback`,
+  `internal/db/dump/pooler_fallback.go`). When a linked dump reaches the direct host
+  from the host process but the `pg_dump` container fails over IPv6, the captured
+  container stderr is classified (`legacyIsIPv6ConnectivityError`) and the dump is
+  retried once through the project's IPv4 transaction pooler
+  (`resolver.resolvePoolerFallback`). This is in addition to the resolver's
+  connect-time pooler fallback for an unreachable direct host.
+  - Remaining divergence: on the no-fallback / failed-retry path, the IPv6
+    suggestion uses the generic `ipv6Suggestion()` text rather than Go's
+    `SuggestIPv6Pooler`, which prefills the project's specific pooler connection
+    string. Surfacing that exact URL needs the pooler string exposed at this seam.

 ## Output
 
 ### `--output-format text` (Go CLI compatible)
 
-Prints `Finished supabase db pull.` on success.
-
-### `--output-format json`
-
-Not applicable.
+Progress to stderr. Migration path: `Creating shadow database...`,
+`Diffing schemas[: <list>]`, `Schema written to <path>`. Declarative path:
+`Preparing declarative schema export using pg-delta...`, `Declarative schema
+written to <dir>`. Plus the `--use-pg-delta` deprecation line and the
+history-update prompt. On success the PostRun line `Finished supabase db pull.`
+is printed to stdout.
 
-### `--output-format stream-json`
+### `--output-format json` / `stream-json`
 
-Not applicable.
+Progress strings still go to stderr; stdout carries a single structured envelope
+`{ declarative, schemaWritten, remoteHistoryUpdated, engine }` and suppresses the
+`Finished supabase db pull.` line.
 
-## Notes
+## Notes / Delegation
 
-- Optional positional argument sets the migration name (defaults to `remote_schema`).
-- `--schema` / `-s` restricts pull to specific schemas.
-- `--db-url`, `--linked` (default true), and `--local` are mutually exclusive.
-- `--declarative` activates declarative pull output through pg-delta (writes `./database` files instead of a migration). `--use-pg-delta` is a deprecated alias.
-- `--diff-engine migra|pg-delta` selects the diff engine for migration-style pull; mutually exclusive with `--declarative` / `--use-pg-delta`. When the flag is omitted, the engine defaults to pg-delta if `[experimental.pgdelta] enabled = true` in `config.toml` (or `EXPERIMENTAL_PG_DELTA`), otherwise migra. An explicit `--diff-engine migra` always forces migra. Enabling pg-delta in config does not switch `db pull` to declarative output.
+- `--declarative` / deprecated `--use-pg-delta` are mutually exclusive with
+  `--diff-engine`; `--db-url` / `--linked` (default) / `--local` are a target group.
+- `--use-pg-delta` is hidden and emits the cobra deprecation line to stderr.
+- The `--experimental` structured-dump branch and the initial-pull `pg_dump` (migra,
+  no local migrations) rebuild the argv and exec the bundled Go binary (their side
+  effects are Go's); the Go child's telemetry is disabled so the single
+  `cli_command_executed` event comes from this TS command.

 ## Output
 
-### `--output-format text` (Go CLI compatible)
-
-Prints query results as a table (default for human mode) or JSON (default for agent mode).
-
-### `--output-format json`
-
-Not applicable (the command has its own `--output` flag for query result format).
-
-### `--output-format stream-json`
-
-Not applicable.
-
-## Notes
-
-- Accepts SQL as a positional argument or via `--file` / `-f`.
-- Also reads SQL from stdin when no positional argument or file is given.
-- `--output` / `-o` controls query result format: `table`, `json`, or `csv` (default varies by agent mode detection).
-- `--db-url`, `--linked`, and `--local` (default true) are mutually exclusive.
-- In agent mode, output defaults to JSON with an untrusted data warning envelope.
+The query payload goes to **stdout** in every `--output-format` mode (Go has no
+`--output-format` for `db query`; there is no machine envelope around the
+payload). Diagnostics (`Connecting to {local|remote} database...`) go to
+**stderr**. DDL/DML with no result columns prints the command tag.
+
+- **table** (default for humans): `olekukonko/tablewriter` v1 box layout, NULL for nil.
+- **json**: a plain rows array for humans, or — in agent mode — the untrusted-data
+  envelope `{advisory?, boundary, rows, warning}` with a random 16-byte hex
+  boundary (`Random`), HTML-escaped exactly like Go's `json.Encoder`, map keys
+  sorted. Agent mode additionally runs a best-effort RLS advisory check (local
+  path only).
+
+### Agent mode
+
+`--agent yes|no|auto` (global). `yes`/`no` force it; `auto` detects an AI tool
+from the environment. Agent mode defaults the format to JSON (table for humans).
+
+## Notes / Divergences
+
+- **`-o` / `--output`.** Go registers a command-local `--output`/`-o`
+  (`json|table|csv`) that shadows the global flag. The Effect CLI extracts global
+  flags from the whole token stream before the leaf parse and builds one tree-wide
+  registry, so a second command-scoped `output` global is impossible
+  (`Parser.createFlagRegistry` throws on duplicate names). Instead the global
+  `LegacyOutputFlag` choice is the UNION of every command's `--output` values
+  (`env|pretty|json|toml|yaml|table|csv`), and the command wrapper enforces this
+  command's own Go enum (`json|table|csv`, declared via `outputFormats` in
+  `query.command.ts`):
+  - `-o json` selects JSON, `-o table` an ASCII table, `-o csv` CSV; an explicit
+    value always wins. With no `-o`, the default is JSON for agents and a table for
+    humans (`cmd/db.go:316-325`).
+  - Values outside the `json|table|csv` enum (`pretty|yaml|toml|env`) are rejected
+    before the handler runs with Go's pflag message — `invalid argument "yaml" for
+"-o, --output" flag: must be one of [ json | table | csv ]` — and exit 1,
+    matching Go's per-command enum validation. See `legacy-go-output-flag.ts`.
+- **Local DDL command tags** use the raw `commandComplete` protocol tag (so
+  `CREATE TABLE` etc. survive node-postgres' first-word-only parse of the tag).
+- **Linked-project cache (`PersistentPostRun` parity).** On the `--linked` path,
+  after the query runs — whether it succeeds or fails — the handler mirrors Go's
+  `ensureProjectGroupsCached` (`apps/cli-go/cmd/root.go:176,214-234`): it issues
+  `GET /v1/projects/{ref}` and writes `supabase/.temp/linked-project.json`. The
+  write is skipped when the file already exists (`supabase link` is authoritative),
+  the access token is missing, or the GET is non-200 — so an auth-failing query
+  still fires the GET but writes nothing. `--local` / `--db-url` never resolve a
+  project ref and so never trigger this request or write (Go gates on
+  `flags.ProjectRef != ""`). Shared with `backups` via `LegacyLinkedProjectCache`.

 ## Output
 
-### `--output-format text` (Go CLI compatible)
-
-Prints `Finished supabase db schema declarative generate.` on success.
-
-### `--output-format json`
-
-Not applicable.
-
-### `--output-format stream-json`
-
-Not applicable.
+Text mode only (no machine envelope). Diagnostics + the final
+`Declarative schema written to <dir>` go to stderr; the PostRun prints
+`Finished supabase db schema declarative generate.` to stdout on success.
 
 ## Notes
 
-- Requires `--experimental` flag or `[experimental.pgdelta] enabled = true` in `config.toml`.
-- `--db-url`, `--linked`, and `--local` are mutually exclusive.
-- In interactive mode (no explicit target), prompts user to choose the source database.
-- `--reset` resets the local database before generating (local data will be lost).
-- `--overwrite` skips the confirmation prompt when declarative schema files already exist.
-- `--no-cache` forces a fresh shadow database setup, bypassing catalog snapshots.
+- Requires `--experimental` or `[experimental.pgdelta] enabled = true`.
+- `--db-url` / `--linked` / `--local` are mutually exclusive; absent all three,
+  smart mode prompts (existing-files overwrite → Local/Custom choice + reset offer).
+- Remote Supabase targets (`--linked` / `--db-url`) get the embedded pg-delta CA
+  bundle written under `supabase/.temp/pgdelta/` and the URL rewritten to
+  `sslmode=verify-ca`; local / non-Supabase targets connect without it.
+- **Architecture:** the shadow-database platform baseline is provisioned by the
+  bundled `supabase-go` via the hidden `db schema declarative __catalog` command
+  (it runs `start.SetupDatabase`'s auth/storage/realtime service migrations). The
+  rest — orchestration, pg-delta diff/export, file writes, prompts — is native.

 ## Output
 
-### `--output-format text` (Go CLI compatible)
-
-Prints generated migration SQL and the path of the created migration file to stderr.
-If `--apply` is set, applies the migration to the local database.
-If `--no-apply` is set, writes the migration file and skips the apply step (no prompt); `--no-apply` overrides global `--yes` and cannot be combined with `--apply`.
-
-### `--output-format json`
-
-Not applicable.
-
-### `--output-format stream-json`
-
-Not applicable.
+Text mode only. The generated SQL, the created-migration path, drop-statement
+warnings, and apply status are written to stderr.
+`--no-apply` writes the migration only (never prompts/applies); `--apply` applies
+without prompting; both override the global `--yes`. `--no-apply` and `--apply`
+are mutually exclusive.
 
 ## Notes
 
-- Requires `--experimental` flag or `[experimental.pgdelta] enabled = true` in `config.toml`.
-- `--file` sets the migration filename stem (default: `declarative_sync`); `--name` overrides the full name.
-- `--no-cache` forces a fresh shadow database setup, bypassing catalog snapshots.
-- `--apply` applies the generated migration to the local database without an interactive prompt.
-- `--no-apply` writes the migration only and never applies it or prompts to apply (for CI/agents); mutually exclusive with `--apply`.
+- Requires `--experimental` or `[experimental.pgdelta] enabled = true`.
+- `--file` sets the migration filename stem (default `declarative_sync`); `--name`
+  overrides it. In a TTY without `--name`/`--yes`, the name is prompted.
+- When no declarative files exist, a TTY offers to generate them (from local) first.
+- The migration apply is native (connects to the local DB and records migration
+  history). On apply failure a debug bundle is written under
+  `supabase/.temp/pgdelta/debug/` and, in a TTY, a reset-and-reapply is offered
+  (the reset itself runs the bundled `supabase-go db reset --local`, since
+  `db reset` is still `wrapped`).
+- **Architecture:** the shadow-database platform baseline (migrations / declarative
+  catalogs) is provisioned by the bundled `supabase-go` via the hidden
+  `db schema declarative __catalog` seam; the diff is native pg-delta.

 ## Output
 
-### `--output-format text` (Go CLI compatible)
+### `--output-format text`
 
-Prints progress and success messages as functions are deployed.
+Prints progress and success messages as Functions are deployed, bundled, uploaded, or pruned.
 
 ### `--output-format json`
 
-Not applicable (proxied to Go binary).
+Emits a structured success payload with the project ref, deployed function slugs, and dashboard URL.
 
 ### `--output-format stream-json`
 
-Not applicable (proxied to Go binary).
+Emits the same structured success payload as a streamed JSON event sequence.
+
+Legacy `--output` / `-o` does not change deploy output, matching the Go command.
 
 ## Notes
 
 - If no function name is provided, deploys all functions found in `supabase/functions/`.
-- Requires a linked project (`--project-ref` or linked project config).
-- Uses Docker by default to bundle functions; `--use-api` switches to server-side bundling.
-- `--prune` deletes functions that exist in the Supabase project but not locally.
-- `--jobs` (`-j`) sets the maximum number of parallel deploys; must be combined with `--use-api`.
-- `--use-docker` and `--legacy-bundle` are hidden flags forwarded to the Go binary for backward compatibility; they are mutually exclusive with `--use-api`.
-- Phase 0 proxy: all invocations are forwarded to the bundled Go binary.
+- Requires a linked project unless `--project-ref` is provided.
+- Uses API/server-side bundling by default; `--use-docker` and `--legacy-bundle` select local bundling.
+- `--use-api`, `--use-docker`, and `--legacy-bundle` are mutually exclusive deploy modes.
+- `--prune` deletes deployed Functions that are not present locally after a confirmation prompt;
+  global `--yes` skips the prompt.

 ## Output
 
 ### `--output-format text` (Go CLI compatible)
 
-Prints a table of Edge Functions with columns for slug, status, version, and region.
+Prints a Glamour-style ASCII table with columns `ID`, `NAME`, `SLUG`, `STATUS`, `VERSION`, and `UPDATED_AT (UTC)`.
 
 ### `--output-format json`
 
-Not applicable (proxied to Go binary).
+Prints a structured success result shaped as `{ "functions": [...] }`.
 
 ### `--output-format stream-json`
 
-Not applicable (proxied to Go binary).
+Prints a structured success result shaped as `{ "functions": [...] }`.
 
 ## Notes
 
-- Requires a linked project (`--project-ref` or linked project config).
-- Phase 0 proxy: all invocations are forwarded to the bundled Go binary.
+- Requires a linked project (`--project-ref`, `SUPABASE_PROJECT_ID`, or `<workdir>/supabase/.temp/project-ref`).
+- Native TypeScript port using the Management API.
+- Go `--output` parity:
+  - `json` emits the raw array.
+  - `yaml` emits the raw array.
+  - `toml` emits `{ functions = [...] }`.
+  - `env` fails with `--output env flag is not supported`.

+temp directory is the only place affected — the project directory is never modified.
 
 ## API Routes

+Management API: none. When a third-party auth provider (`auth.third_party.*`) is
+enabled, two outbound HTTPS GETs are made per start to build `SUPABASE_JWKS`:
+
+| Method | Path                                            | Auth | Request body | Response (used fields) |
+| ------ | ----------------------------------------------- | ---- | ------------ | ---------------------- |

+| `GET`  | `<jwks_uri>` (from discovery)                   | none | `—`          | `keys`                 |
+
+Both fetches use a 10s timeout and are best-effort: failure logs nothing and falls
+back to local keys (matching the Go CLI, which ignores the error). No scheme/host

 ## Output
 
 ### `--output-format text` (Go CLI compatible)
 
-Prints startup information and live request logs as functions are invoked.
+Writes lifecycle text to stderr / stdout while the command is running:
+
+- `Setting up Edge Functions runtime...` before each container start
+- `Skipped serving Function: <slug>` for disabled functions
+- `File change detected: <path> (<op>)` when a watched file triggers a restart
+- live `docker logs -f --timestamps` output from the edge-runtime container
+- `Stopped serving supabase/functions` on clean shutdown
 
 ### `--output-format json`
 
-Not applicable (proxied to Go binary).
+Long-running raw log / error output only; there is no final success payload object for this command.
 
 ### `--output-format stream-json`
 
-Not applicable (proxied to Go binary).
+Long-running raw log / error events only; there is no terminal `result` event on success.
 
 ## Notes
 
-- Serves all functions locally using Deno and the Supabase Edge Runtime (via Docker).
-- `--no-verify-jwt` disables JWT verification for development.
-- `--env-file` path to env file populated to Function environment.
-- `--import-map` path to custom import map.
-- `--inspect` / `--inspect-mode` activates Deno inspector for debugging.
-- `--all` is a hidden flag (default true) retained for backward compatibility; it has no effect because the Go CLI always serves all functions.
-- Phase 0 proxy: all invocations are forwarded to the bundled Go binary.
+- The hidden `--all` flag is still parsed but ignored; the native port always serves every discovered function, matching the Go command.
+- Each restart re-reads config, rebuilds per-function bind mounts, recreates the `supabase_edge_runtime_<project>` container, and best-effort reloads Kong afterwards.
+- The command creates or reuses Docker resources derived from the resolved project id:
+  - container: `supabase_edge_runtime_<project>`
+  - named volume: `supabase_edge_runtime_<project>`
+  - network: `supabase_network_<project>` unless `--network-id` overrides it
+- Inspector mode exposes the configured `edge_runtime.inspector_port` on the host and sets `SUPABASE_INTERNAL_WALLCLOCK_LIMIT_SEC=0`, matching the Go serve path.
+- Config `env()` interpolation uses a project environment resolved by the command itself (ambient `process.env` layered under `.env.<env>.local` / `.env.local` / `.env.<env>` / `.env`, matching Go) and passed into `loadProjectConfig`. The command does not mutate `process.env` or move/hide any project files.
+- A container crash terminates the command with a non-zero exit; only a watched-file change restarts the container. The Go CLI never auto-restarts a crashed container.

+### Storage gateway routes (local and remote)
+
+**Local:** `api.external_url` (default `http://<host>:54321`, where `<host>` follows Go's
+`utils.GetHostname`: `SUPABASE_SERVICES_HOSTNAME` → TCP `DOCKER_HOST` → `127.0.0.1`).
+
+**Remote (`--linked`):** `https://<ref>.<projectHost>` (default host: `supabase.co`).
+
+Auth: an `apikey` header set to the service-role key; an `Authorization: Bearer <key>`
+header is also sent, except when the key is an opaque `sb_...` key, which Go's
+`withAuthToken` (`pkg/fetcher/gateway.go:22`) treats as a non-JWT and omits.

+
+A bucket that omits `file_size_limit` (or sets it to `0`) inherits the
+storage-level `[storage].file_size_limit` (Go `config.go:753-756`). The
+storage-level limit and all bucket sizes are parsed up front (the storage-level
+one unconditionally, even with only vector buckets), so an invalid value fails
+before any Storage call.
+`file_size_limit` is omitted from the body when the resolved value is `0`;
+`allowed_mime_types` is omitted when empty (Go `omitempty`).
+
+Analytics bucket routes (`/storage/v1/iceberg/...`) are only reached when
+`[storage.analytics].enabled = true` AND `--linked` is passed.
+
+### Management API routes (remote `--linked` only, when env var not set)
+

 ## Output
 
 ### `--output-format text` (Go CLI compatible)
 
-Prints progress and success messages as buckets are created.
+All progress is written to **stderr** (stdout stays empty), byte-matching Go:
+
+```
+Creating Storage bucket: <name>
+Updating Storage bucket: <id>
+Updating analytics buckets...
+Bucket already exists: <name>
+Creating analytics bucket: <name>
+Pruning analytics bucket: <name>
+Updating vector buckets...
+Bucket already exists: <name>
+Creating vector bucket: <name>
+Pruning vector bucket: <name>
+Uploading: <objects_path>/<rel> => <bucket>/<rel>
+Skipping non-regular file: <path>
+WARNING: Vector buckets are not available in this project's region yet. Skipping vector bucket seeding.
+WARNING: Vector buckets are not available in the local storage service. If this project is linked, run `supabase link` to update service versions, then restart the local stack. Skipping vector bucket seeding.
+```
+
+Interactive (TTY) prompts:
+
+```
+Bucket <id> already exists. Do you want to overwrite its properties? [Y/n]
+Bucket <name> not found in supabase/config.toml. Do you want to prune it? [y/N]
+```
 
 ### `--output-format json`
 
-Not applicable (proxied to Go binary).
+Additive (no Go equivalent). A final `result` object summarising the run is
+emitted on stdout; progress/prompts are suppressed (prompts use their defaults:
+overwrite → yes, prune → no).
 
 ### `--output-format stream-json`
 
-Not applicable (proxied to Go binary).
+Additive. NDJSON events; the operation's progress lines are suppressed from
+stdout and a terminal `result`/`error` event is emitted.
 
 ## Notes
 
-- Seeds storage buckets declared in `[storage.buckets]` in `supabase/config.toml`.
-- `--local` (default `true`) seeds the local database.
-- `--linked` seeds the linked project.
-- Phase 0 proxy: all invocations are forwarded to the bundled Go binary.
+- **Remote (`--linked`) — config override merge.** The project ref is resolved
+  BEFORE config is loaded. `loadProjectConfig` then merges the `[remotes.<name>]`
+  block whose `project_id` equals the resolved ref over the base config (including
+  `storage.buckets`, `storage.vector`, `storage.analytics`), mirroring Go's
+  `Config.ProjectId = ProjectRef` → `config.Load` sequence (`config.go:505-518`).
+  Local runs load the base config verbatim with no merge.
+- **Remote (`--linked`).** The remote base URL is `https://<ref>.<projectHost>`
+  (default: `supabase.co`). The service-role key is read from
+  `SUPABASE_AUTH_SERVICE_ROLE_KEY` if set; otherwise fetched via
+  `GET /v1/projects/{ref}/api-keys?reveal=true`.
+- **Bucket name validation.** Every `[storage.buckets]` name is validated against
+  Go's `ValidateBucketName` regex (`^(\w|!|-|\.|\*|'|\(|\)| |&|\$|@|=|;|:|\+|,|\?)*$`,
+  `config.go:1382`) before any Storage call. Invalid names exit `1` with the exact
+  Go error message. Vector and analytics bucket names are NOT validated.
+- **Local env-var overrides.** For local runs, `SUPABASE_AUTH_JWT_SECRET` (if set
+  and non-empty) overrides `auth.jwt_secret`, and `SUPABASE_AUTH_SERVICE_ROLE_KEY`
+  (if set and non-empty) overrides `auth.service_role_key`, mirroring Go's Viper
+  `AutomaticEnv`+`SUPABASE_` prefix (`config.go:492-497`). The `<16`-char rejection
+  applies to the resolved secret (env or config value).
+- **Analytics buckets.** Analytics bucket upsert (`/storage/v1/iceberg/...`) is
+  gated on `[storage.analytics].enabled = true` AND `--linked`. It is never
+  reached for local runs. Errors from analytics routes propagate (no graceful skip).
+- **Vector graceful skip.** When vector buckets are configured but the local
+  service does not support them (`FeatureNotEnabled`, `Vector service not
+configured`, or a 404 on `ListVectorBuckets`), a WARNING is printed and object
+  upload still proceeds; the command exits `0`.
+- **Idempotent.** Existing buckets are updated (after an overwrite confirm),
+  objects are uploaded with `x-upsert: true`.
+- **Content-Type** for uploaded objects mirrors Go (`objects.go:77-108`): the first
+  512 bytes are sniffed with a 1:1 port of `http.DetectContentType`
+  (`legacy/shared/legacy-detect-content-type.ts`), and only a generic `text/plain`
+  result is refined by extension via Go's built-in `mime` table. (Go's
+  `mime.TypeByExtension` also consults the host OS MIME database, which is
+  host-dependent and not reproduced; the deterministic built-in table is used.)
+- **Local Kong TLS.** When `[api.tls] enabled = true` for a local stack, the
+  cert/key pairing is validated before seeding (Go `(*api).Validate`, `config.go:845-861`):
+  `cert_path` and `key_path` must both be set or both absent; setting only one exits `1`.
+  When both are set, both files are read for validation; `cert_path` provides the CA PEM
+  used to trust the Kong gateway. If neither is set, the embedded `kong.local.crt` constant
+  is used. Resolved against `<workdir>/supabase/` (or absolute path as-is). The CA is
+  injected into Bun's `fetch` via `tls: { ca: <pem> }` — no system trust store modification.

A path that is a **file** is mounted via its **containing directory** (not the lone file) so that psql `\ir`/`\i` includes — which resolve relative to the test file's own directory — find their sibling files inside the container (CLI-1139). Directory paths are mounted as-is. Mounts are deduped by container target, so multiple files in the same directory produce a single `-v`.

+# 0013. Hybrid Stitch + Stamp for Telemetry Identity Attribution
+
+**Status**: proposed
+**Date**: 2026-06-11
+
+## Problem Statement
+
+CLI telemetry attributes events to an anonymous device ID until the user authenticates. Linking the two identities ("stitching") originally fired `$create_alias` + `$identify` on every first-authenticated-run. In environments where `~/.supabase/` does not persist between invocations (CI runners, Docker, `npx supabase`), every run looked like a first run, producing a 730K/day `$identify` spike (vs ~15K baseline; see GROWTH-886, #5366). The emergency fix gated stitching off in those environments, which stopped the spike but orphaned all CI/Docker/npx events at the device level — no user attribution at all.
+
+GROWTH-891 proposed "Option C": never fire `$create_alias` or `$identify` anywhere; instead stash the user UUID (from the `X-Gotrue-Id` response header) in process memory and use it as `distinct_id` on subsequent capture events ("stamping"). Zero extra events, attribution restored.
+
+Pure Option C has a hidden cost: `$create_alias` does two jobs. It labels future events (which stamping replaces for free) **and** retroactively merges past anonymous events into the user's person profile (which stamping cannot do). On a developer laptop, a user may run the CLI anonymously for weeks before first login; pure Option C would orphan that history permanently.
+
+## Decision
+
+Use a hybrid of stitching and stamping, differentiated by environment:
+
+- **Stamp everywhere.** After the first authenticated API call in a process, all subsequent capture events use the user UUID as `distinct_id` directly. No extra PostHog events.
+- **Stitch only in persistent environments.** On a developer laptop's first login, additionally fire exactly one `$create_alias` (no `$identify`) to merge pre-login history, and persist the UUID to `~/.supabase/telemetry.json` so later runs start identified. In ephemeral environments (detected as `isCI || (isFirstRun && !isTTY)`), never alias and never write state.
+- **The gate lives inside `StitchLogin`,** not at call sites. The function always stashes the UUID in memory; the persistent-only side effects (alias + state write) branch internally. Rationale: the previous call-site gate was added to the `OnGotrueID` hook but missed the `login` command's direct call, quietly leaking aliases from CI `supabase login --token` runs. Centralizing makes the gate unforgettable for future callers.
+- **Memory wins over disk.** When the in-process UUID and the persisted `distinct_id` disagree (e.g. re-login as a different user), the in-memory value is used.
+- **Logout resets the identity entirely.** Logout wipes the in-memory UUID and the persisted `distinct_id`, and **rotates the device ID**. Rotation makes cross-account contamination structurally impossible: a later login as a different account aliases a fresh device instead of one already merged into the previous user's person graph. Transient failure paths (e.g. a profile lookup error during login) only clear the identity and keep the device ID, preserving anonymous-history continuity.
+- **All three identity surfaces change together:** the Go CLI (`apps/cli-go/internal/telemetry/`), the legacy TS shell (`apps/cli/src/legacy/auth/legacy-platform-api.layer.ts`), and the next TS shell (`apps/cli/src/next/commands/login/`).
+
+## Considered Options
+
+- **Pure Option C (no alias anywhere).** Rejected: silently abandons the retroactive history merge on persistent laptops, where it has real value and where alias volume (~7K/day post-GROWTH-890) was never the problem. The volume pathology came entirely from ephemeral environments.
+- **Keep the ephemeral gate at call sites.** Rejected: already failed once — the `login` command path never received the gate that the hook path got, the exact bug shape this redesign exists to prevent.
+- **Status quo (gate from #5366 only).** Functional but permanently orphans all CI/Docker/npx events. Those populations are 31–85% of CLI volume and feed dashboards (Agent-Led Growth).
+
+## Consequences
+
+- `isEphemeralIdentityRuntime` survives as a live branch (the ticket originally planned to delete it). Its meaning changes from volume guard to "is a stitch worth anything here?" — a false positive now silently drops a laptop user's history merge instead of saving spam, so the heuristic deserves test coverage in its own right.
+- Events fired before the first authenticated call in a process remain device-scoped in ephemeral environments (typically 0–3 events per run). Accepted loss.
+- The TS shells need a mutable identity slot consulted at capture time, replacing the startup-snapshot-only `runtime.distinctId`.
+- `$identify` is fully retired from the stitch path on all surfaces (it survives only where person properties are genuinely set).
+- `$create_alias` fires only for the **first** identity a device ever sees. Re-login (or the login command's direct stitch after the response hook already stitched) stamps and persists without re-aliasing — re-aliasing an already-merged device would attempt to merge unrelated person graphs.
+- In the TS shells, the rotated device ID takes effect from the next process; capture events in the tail of the logout process itself still carry the startup device-ID snapshot. Go rotates in-process as well.

+# 0013. Live E2E Tests Bypass the Replay Server
+
+**Status**: accepted
+**Date**: 2026-06-16
+
+## Problem Statement
+
+The CLI has no true end-to-end tests. `apps/cli-e2e` is a replay/record harness:
+in **replay** mode it serves recorded HTTP fixtures (fast, deterministic, no
+network); in **record** mode it proxies the CLI's Management API and Docker
+traffic to staging only to *capture* those fixtures. Tests always assert against
+replayed fixtures, never live responses. Behaviour that cannot be mocked — real
+Management API calls and the real Docker bundler (e.g. `functions deploy`) — is
+therefore untested.
+
+[CLI-1630](https://linear.app/supabase/issue/CLI-1630/set-up-proper-live-e2e-tests-for-the-cli)
+adds a structured Vitest **live** suite that runs the real CLI against a real
+backend (staging today, the dockerized `supabox` stack later) as a non-blocking
+smoke test before a stable deploy.
+
+The open architectural question was *how* live mode should reach the backend.
+The first instinct was to add a third runtime mode inside `replay-server.ts`
+alongside `replay` and `record` — taking record mode's passthrough path
+(CLI → replay server → real API) but skipping fixture I/O. That keeps the
+existing Docker and storage proxies "for free."
+
+## Decision
+
+Live mode **does not route through the replay server**. It is a harness-wiring
+mode, not a `replay-server.ts` branch.
+
+- Live tests reuse `createHarness`/`exec` from `@supabase/cli-test-helpers`, but
+  the harness is wired **directly**: `apiUrl = CLI_E2E_API_URL` (the real
+  Management API) and `DOCKER_HOST` points at the **real Docker socket**.
+- `replay-server.ts` is untouched — no `live` branch, no live Docker or storage
+  proxy.
+- Assertions are **outcome-based**, modeled on the manual deploy playbook:
+  1. run the real CLI (`run([...])`) and assert `exitCode` / `stdout`;
+  2. **invoke the deployed function over HTTP directly** and assert HTTP status +
+     the JSON body the function itself returns (e.g. `{case, ok:true}`).
+  The invoke is a direct HTTP call to `https://{ref}.{CLI_E2E_PROJECT_HOST}/functions/v1`,
+  not a proxied call — the replay server is nowhere in the assertion path.
+- Because the assertion target is the function's own deterministic response (plus
+  exit codes / stdout substrings), the suite is **ID-agnostic** — no response
+  normalization or snapshot machinery by default. The function invoke URL and
+  anon key are resolved at setup from the freshly created project (anon key via
+  `GET /v1/projects/{ref}/api-keys`).
+
+The CLI target is a CI **matrix axis** (`CLI_HARNESS_TARGET`): each target runs
+as its own job with `fail-fast: false`, so each implementation is independently
+green/red. The pilot covers `go` (raw Go binary) and `ts-legacy` (the TS rewrite
+that shells out to Go for most commands and runs native TS logic for ported
+ones); `ts-next` is a later axis.
+
+## Rationale
+
+For the assertions live mode actually makes, intercepting the Management API buys
+nothing — nothing inspects a proxied API body. The only thing the replay server
+would do in live mode for `functions deploy` is relay Docker traffic
+(CLI → relay → real socket) through its streaming/idle-timeout proxy. That
+streaming relay is the most complex, most failure-prone code path in the harness,
+and it would sit in front of the slowest, flakiest real operation (image pull +
+bundle) for zero assertion benefit. Pointing `DOCKER_HOST` at the real socket
+removes that failure surface entirely.
+
+Keeping `replay-server.ts` out of the live path also means live and record modes
+stay decoupled: record mode's destructive fixture-tree rewrite, scenario logging,
+and placeholder normalization never have to grow `isLive` guards, and a future
+reader is not left wondering why a "transparent proxy" mode exists that records
+nothing.
+
+The storage proxy (the other "free" proxy) is not exercised by the
+`functions deploy` pilot, so it is not a reason to keep the server in front. If a
+later live command genuinely needs host rewriting (e.g. storage on a different
+host than the Management API), a scoped passthrough can be introduced *then* for
+that command — YAGNI until a concrete need exists.
+
+The per-target matrix exists because `go` and `ts-legacy` are different code
+paths reaching the same backend; running them as separate jobs gives two
+independent green signals instead of one averaged result.
+
+## Consequences
+
+### Positive
+
+- The live path has fewer moving parts: no proxy, no streaming relay, no fixture
+  guards. The Docker bundler talks to the real daemon as users' machines do.
+- `replay-server.ts` and the replay/record contract are unchanged, so the
+  PR-blocking `e2e` suite is unaffected.
+- Tests are trivial to add: drop a `deploy-e2e-foo` fixture function returning a
+  known body, add one `testLive` that runs deploy → invoke → asserts body.
+- Retargeting from staging to `supabox` is genuinely an env swap
+  (`CLI_E2E_TARGET_ENV` + `CLI_E2E_API_URL` + `CLI_E2E_PROJECT_HOST` + token),
+  because assertions key off function output, not hostnames.
+
+### Negative
+
+- Live mode requires a working Docker daemon on the runner (enforced by a
+  `docker info` preflight) — unlike the replay suite, which served Docker
+  fixtures and needed no daemon.
+- Each live run provisions and tears down a real staging project, so the suite is
+  inherently slower and subject to provisioning flake. Mitigated by a CI-level
+  re-run (up to 3×) rather than in-setup retry.
+- A second wiring path now exists for the same harness (replay-via-server vs
+  live-direct); contributors must know which mode wires the CLI how.
+
+## Alternatives Considered
+
+1. **Third `live` branch inside `replay-server.ts`** (the initial plan): rejected.
+   It adds `isLive` guards throughout record-mode code, keeps the fragile Docker
+   stream relay in the hot path for no assertion benefit, and couples live mode to
+   machinery it does not use.
+2. **Snapshot/normalization-first assertions**: rejected as the default. Outcome
+   assertions on function bodies are naturally ID-agnostic; a scoped normalizer is
+   added only if a future case makes CLI diagnostic output itself the assertion
+   target.
+3. **Single CLI target**: rejected. `go` and `ts-legacy` are distinct
+   implementations of the same commands; one job would hide a regression in
+   whichever target was not chosen.
+4. **One shared long-lived staging project**: rejected. State would leak between
+   runs and overlapping runs would collide; ephemeral per-job projects with
+   scoped teardown keep runs isolated.
