-## History
-
-The CLI was originally a two-binary distribution during its gradual port from a Go CLI to
-TypeScript: a `supabase` Bun single-file executable alongside a `supabase-go` binary that the TS
-CLI proxied to for not-yet-ported commands. The port completed (CLI-1970), the last residual
-delegation surface was removed (CLI-2432), and the Go source tree (`apps/cli-go/`) was deleted in
-the same effort — the CLI now ships as a single compiled binary per platform. See
-[ADR 0030](../../../docs/adr/0030-go-cli-removal.md) for the full removal record.

 ## Notes
 
 - Effect CLI's `--completions` global flag remains exposed at the root; it is not
   the compatibility path and is not what this subcommand routes through.
-- **Known divergence (CLI-1906):** the old Go CLI exited `0` on both bare
-  `completion` (no shell subcommand) AND `completion <unknown-shell>` — an
-  unrecognized subcommand name was treated the same as a missing one, printing
-  help and returning success. The TS CLI currently exits `1` for
-  both invocations; this is a real, systemic exit-code bug in the shared CLI
-  harness (`shared/cli/run.ts`), not `completion`-specific — it reproduces on
-  any bare or unrecognized-subcommand invocation of a group command with
-  subcommands (e.g. `branches`, `branches bogus-subcommand`). See CLI-1906 for
-  the fix; this doc describes current (buggy) behavior, not the intended
-  target.

-- **Documented divergences from the old Go CLI (intentional):**
-  - `--include-raw-output` is declared as a normal boolean **on each subcommand** (the old Go CLI declared it as a persistent flag on the `domains` group). Two consequences: (a) it must appear after the subcommand name (`domains get --include-raw-output`) rather than before it (`domains --include-raw-output get`), matching how `--project-ref` is already handled shell-wide; (b) it cannot reproduce the old help-hiding or the `Flag --include-raw-output has been deprecated` stderr warning, which Effect CLI has no hook for. It still reproduces the behavioral effect (forces `-o json` when `-o` is unset/pretty); on `delete` it is inert.
-  - The degenerate `validation_records != 1` status message approximates a Go-style `%+v` struct dump (which embeds a non-deterministic pointer address).
-  - Text-mode status output is newline-terminated even where the old CLI's output wasn't. Without the final newline, interactive shell prompts can redraw over the last status line, hiding the ACME TXT record.
-  - In a structured `-o` mode the human status is suppressed on stderr, keeping stdout clean and matching the parity contract.
+- **Notes:**
+  - `--include-raw-output` is declared as a normal boolean **on each subcommand**. Two consequences: (a) it must appear after the subcommand name (`domains get --include-raw-output`) rather than before it (`domains --include-raw-output get`), matching how `--project-ref` is already handled shell-wide; (b) it is not hidden from help and emits no `Flag --include-raw-output has been deprecated` stderr warning, since Effect CLI has no hook for either. It forces `-o json` when `-o` is unset/pretty; on `delete` it is inert.
+  - The degenerate `validation_records != 1` status message is an approximate struct dump (the exact text is not stable).
+  - Text-mode status output is newline-terminated. Without the final newline, interactive shell prompts can redraw over the last status line, hiding the ACME TXT record.
+  - In a structured `-o` mode the human status is suppressed on stderr, keeping stdout clean.
   - The CNAME pre-check's "failed to locate" error text embeds a readable, 1024-byte-capped JSON dump of the DNS answers, rather than an uncapped decimal byte-value array — see `domains.cname.ts`'s comment at the failure site for detail.

It is delivered into the created (not yet started) container as a `docker cp` stdin tar archive at `/root/index.ts` — never a single-file host bind mount, which materializes as an empty directory on daemons that cannot see the client's filesystem (remote `DOCKER_HOST`/Docker-context daemons, podman machines) and breaks bring-up with edge-runtime's "failed to determine entrypoint" (supabase/cli#6254). Only this bootstrap template is daemon-independent: user function sources, import maps, static files, and the multiline-env script directory (present only when an env value contains a newline) still arrive by host bind mounts, so they require a daemon that can see the project directory.
 - The aggregated bind mount list is pruned before `docker create`: a bind is dropped when another bind of the same mode already supplies the same content at the same container path — a file bind nested inside an already-bound read-only package directory would otherwise make the bootstrap `docker cp` fail with `destination "<container>:/" must be a directory` (supabase/supabase#50088). Pruned paths remain visible in the container through their covering parent mounts; the `--workdir` gate and the file-watch set are computed from the unpruned aggregate.
 - Existing local values declared under an import map's `scopes` are explicit read-only Docker mounts and may resolve outside the nearest Git root; each distinct out-of-root host path prints one `WARN` during bring-up, deduplicated across Functions sharing an import map. Such out-of-root mounts are excluded from the file-watch set per Function, so a scope target contributes no watch root of its own and cannot enlarge or destabilise the watcher; a path that another Function reaches through its ordinary binds is still watched. Other file-valued binds are watched through their immediate parent non-recursively, while directory binds remain recursive. Missing targets retain serve's existing skip behavior.
-- **Intentional divergence from Go — spec-strict import-map key matching (CLI-2179, ruled 2026-08-12):** bind mounts are computed by the functions import scanner (`walkImportPaths`/`substituteImportMapValue`, shared with `functions deploy` and `start`'s Edge Runtime bring-up), which matches import-map keys per the import-maps spec Deno/edge-runtime implement — exact match, or prefix match only for a `/`-suffixed key — instead of Go's any-key `strings.HasPrefix` (`pkg/function/deno.go:150-155`). Bind mounts may shrink vs the Go CLI for maps that relied on bare-key prefix matching; an unwalkable target (`ENOTDIR` — a value routed through a file) is skipped with a `WARN`.

   no baseline query, `Finished …` still prints) — the opposite of `migration repair`/`fetch`/
   `down`, which treat a decline as a cancellation.
-- **Atomicity note:** the old Go CLI sent the baseline `DELETE`/`INSERT` via a batched pipeline
-  (not an explicit transaction) — a partial failure could leave the DELETE applied without the

-  error (matching `migration repair`'s own equivalent divergence); the success path produces
-  the same output as before.
-- **Documented divergences** (neither reproduced, both judged strictly worse to replicate):
-  (a) the old Go CLI's line-scanning silently truncated `lineByLineDiff`'s output when a
-  single dumped line exceeded 64 KiB, with no error surfaced — not reproduced (`squash.diff.ts`);
-  (b) the old Go CLI's separator-comment write discarded its error return, while the
-  auth/storage diff write right after it was checked — this port combines both into one write,
-  so a hypothetical failure isolated to just the separator bytes now surfaces as
-  `failed to write line: …`; not realistically triggerable on a real filesystem for a single
-  already-open file descriptor.

 - UUID validation runs **after** project-ref resolution but **before** the API call. Error messages: `invalid snippet ID: invalid UUID length: N` for malformed lengths, `invalid snippet ID: invalid UUID format` for length-36 inputs with wrong dash positions or hex chars.
 - The linked-project cache fires after project-ref resolves; the telemetry state always flushes. Both run on success and on every error path — including invalid-UUID early-exit — via the two `Effect.ensuring` blocks in the handler.

 ## Notes
 
 - `--type saml` is **required**.
-- `--metadata-file` and `--metadata-url` are mutually exclusive. Violations emit the exact template: `if any flags in the group [metadata-file metadata-url] are set none of the others can be; [metadata-file metadata-url] were all set`. "Set" follows `pflag.Changed` semantics — an explicit empty value (`--metadata-file=`) still counts.
-- Flag values follow pflag's consumption rules, not the TS parser's: every value the handler acts on (`--project-ref`, `--metadata-file`, `--metadata-url`, `--attribute-mapping-file`, `--domains`, `--name-id-format`, `--skip-url-validation`) is reconciled against a pflag-faithful raw-argv scan. E.g. `--project-ref --metadata-file x.xml --metadata-url u` hands `--metadata-file` to `--project-ref` as its value and fails ref validation — the metadata file is never read (CLI-1982). Repeated flags resolve last-wins (pflag Sets every occurrence; the TS parser is first-wins), and an occurrence pflag's `Value.Set` would reject — `--type` outside `[ saml ]`, a boolean outside the accepted spellings (`--skip-url-validation=yes`), or a `--name-id-format` outside the enum — fails with pflag's exact `invalid argument …` message before every validation and request.
-- Required-ness follows pflag too: when the `--type` token is itself consumed as another flag's value (`--domains --type saml`), the command fails with the exact `required flag(s) "type" not set` before any request (required-flags validation runs before flag-group validation). `-t` shorthand occurrences are recognised by the scan and never trip this.
-- The workdir follows pflag/viper too: the workdir-change step chdir's to the effective `--workdir` (last occurrence, even a flag-shaped consumed token like `--workdir --metadata-file`) or `SUPABASE_WORKDIR`, and a missing directory aborts with the exact `failed to change workdir: chdir …` before the required-flag check, the mutex check, and any request. A changed-but-empty `--workdir=` shadows the env var and falls back to the always-valid project-root walk-up, exactly like viper.
-- The profile follows pflag/viper too (PR #5974 round 7): whenever the pflag-effective `--profile`/`SUPABASE_PROFILE` token differs from the one the Effect parser gave the config layer (a `--profile` token consumed by another flag — `--domains --profile alternate.yml` targets the env/default profile, not `alternate.yml`; a flag-shaped consumed value — `--profile --metadata-url`; repeats, which pflag resolves last-wins; an explicit `--profile supabase` shadowing the env; an untrimmed/empty persisted `~/.supabase/profile` file), the handler re-runs the profile loader on the effective token (`profile-load.ts`) — the POST targets that profile's `api_url`, and a token that can't be loaded aborts with the matching error (`failed to read profile: …` / `failed to parse profile: …` / `invalid profile: …`, byte-exact for the deterministic classes) before the workdir check and any request. Where the scan and the parser agree — every normal invocation — the config layer's resolution (including its pre-existing lenient missing/malformed-file fallback, which predates CLI-1982 and applies shell-wide) is used unchanged. The upgrade-gate fallback GETs and the linked-project cache fill also target the reconciled host.
-- Accepted micro-divergences of the profile emulation (each fail-closed: both CLIs exit 1 with zero requests; only stderr detail can differ): YAML parse-failure detail text (JS `yaml` vs go-yaml, shared `failed to read profile: While parsing config: ` prefix); non-YAML/JSON viper config types (`.toml`, `.env`, …) parsed as YAML; `http_url`/`hostname_rfc1123`/`uuid4` validator tags approximated; the final line of a padded multi-line error loses its trailing spaces to the shared error normalizer's trim. Also: when the effective and layer profiles differ AND the token is keyring-relevant, the keyring token lookup still uses the layer profile's name (env-token flows, e.g. the cli-e2e harness, are unaffected), and the upgrade-suggestion billing URL keeps the layer profile's dashboard host.
+- `--metadata-file` and `--metadata-url` are mutually exclusive. Violations emit the exact template: `if any flags in the group [metadata-file metadata-url] are set none of the others can be; [metadata-file metadata-url] were all set`. "Set" means explicitly passed — an explicit empty value (`--metadata-file=`) still counts.
+- Flag values are resolved by a raw-argv scan rather than the TS parser: every value the handler acts on (`--project-ref`, `--metadata-file`, `--metadata-url`, `--attribute-mapping-file`, `--domains`, `--name-id-format`, `--skip-url-validation`) is reconciled against that scan. E.g. `--project-ref --metadata-file x.xml --metadata-url u` hands `--metadata-file` to `--project-ref` as its value and fails ref validation — the metadata file is never read (CLI-1982).

+- Required-ness uses the same scan: when the `--type` token is itself consumed as another flag's value (`--domains --type saml`), the command fails with the exact `required flag(s) "type" not set` before any request (required-flags validation runs before flag-group validation). `-t` shorthand occurrences are recognised by the scan and never trip this.

 - Metadata URL validation error message: `only HTTPS Metadata URLs are supported Use --skip-url-validation to suppress this error` (no trailing period; differs from `sso update`'s variant).
-- The `## Attribute Mapping` / `## SAML 2.0 Metadata XML` sections are emitted as plain markdown (heading + fence). Visual styling of the headings does not match the old Glamour-rendered output; the XML body inside the fence is byte-parity via `formatSsoMetadataXml`.
-- **Missing `--type` parser error**: the error message itself is `Error: required flag(s) "type" not set` verbatim (mapped in `shared/output/normalize-error.ts`). Effect CLI's parser however dumps the full help block to stdout _before_ the error, unlike the old CLI, which showed usage only on explicit `--help`. The error string is unchanged; the surrounding help dump is an Effect CLI behavior that would require forking the CLI parser to suppress.

-- The old Go CLI's markdown source included a trailing space in the `Single sign-on URL (ACS URL) ` label, but Glamour collapses it when computing column widths.

 - `--metadata-file` and `--metadata-url` are mutually exclusive.
-- Flag values follow pflag's consumption rules, not the TS parser's: every value the handler acts on (`--project-ref`, `--metadata-file`, `--metadata-url`, `--attribute-mapping-file`, the three domain slices, `--name-id-format`, `--skip-url-validation`) is reconciled against a pflag-faithful raw-argv scan — same mechanism as `sso add` (CLI-1982). Repeated flags resolve last-wins (pflag Sets every occurrence; the TS parser is first-wins), and an occurrence pflag's `Value.Set` would reject — a boolean outside the accepted spellings (`--skip-url-validation=yes`), or a `--name-id-format` outside the enum — fails with pflag's exact `invalid argument …` message before any validation or request.
-- Positional arity follows pflag too: the exact-one-argument rule is re-counted over pflag-effective positionals (arity validation runs before every hook and flag validation), so a consumed flag token that orphans its parser-value (`--domains --metadata-url u <id>`) fails with the exact `accepts 1 arg(s), received 2` before the GET — and wins over both the mutex and invalid-UUID errors.
-- The workdir follows pflag/viper too: the workdir-change step chdir's to the effective `--workdir` (last occurrence, even a flag-shaped consumed token like `--workdir --metadata-file`) or `SUPABASE_WORKDIR`, and a missing directory aborts with the exact `failed to change workdir: chdir …` after the arity check but before the mutex checks and any request. A changed-but-empty `--workdir=` shadows the env var and falls back to the always-valid project-root walk-up, exactly like viper.
-- The profile follows pflag/viper too (PR #5974 round 7): whenever the pflag-effective `--profile`/`SUPABASE_PROFILE` token differs from the one the Effect parser gave the config layer (repeats — pflag is last-wins where the parser is first-wins, so `--profile a.yml --profile b.yml` GETs and PUTs `b.yml`'s `api_url`; a flag-shaped consumed value — `--profile --add-domains`; an explicit `--profile supabase` shadowing the env; an untrimmed/empty persisted `~/.supabase/profile` file), the handler re-runs the profile loader on the effective token (`profile-load.ts`). Both the initial GET and the PUT then target that profile's `api_url` — the GET is issued through the raw HTTP client because the typed client bakes the layer's `api_url` in at construction — and a token that can't be loaded aborts with the matching error (`failed to read profile: …` / `failed to parse profile: …` / `invalid profile: …`, byte-exact for the deterministic classes) after the arity check, before the workdir and mutex checks and any request. The raw GET mirrors the old typed client's behavior on the 200 path too: an undecodable JSON body aborts with `failed to get sso provider: <detail>` before any PUT (detail text is JS `JSON.parse`'s — micro-divergence), a 200 without a JSON content type falls into the gate + unexpected-status branch, and the response is stitched through the shared per-command identity guard exactly like the typed client. The upgrade-gate fallback GETs and the linked-project cache fill also target the reconciled host. Where the scan and the parser agree — every normal invocation — the config layer's resolution (including its pre-existing lenient missing/malformed-file fallback, which predates CLI-1982 and applies shell-wide) is used unchanged, via the typed client.
-- Accepted micro-divergences of the profile emulation (each fail-closed: both CLIs exit 1 with zero requests; only stderr detail can differ): YAML parse-failure detail text (JS `yaml` vs go-yaml, shared `failed to read profile: While parsing config: ` prefix); non-YAML/JSON viper config types (`.toml`, `.env`, …) parsed as YAML; `http_url`/`hostname_rfc1123`/`uuid4` validator tags approximated; the final line of a padded multi-line error loses its trailing spaces to the shared error normalizer's trim. Also: when the effective and layer profiles differ AND the token is keyring-relevant, the keyring token lookup still uses the layer profile's name (env-token flows, e.g. the cli-e2e harness, are unaffected), and the upgrade-suggestion billing URL keeps the layer profile's dashboard host.
+- Flag values are resolved by a raw-argv scan rather than the TS parser: every value the handler acts on (`--project-ref`, `--metadata-file`, `--metadata-url`, `--attribute-mapping-file`, the three domain slices, `--name-id-format`, `--skip-url-validation`) is reconciled against that scan — same mechanism as `sso add`.

 - Always performs the GET pre-check, regardless of whether `--add-domains` / `--remove-domains` are used.
 - Domain merge: removals are applied first, then additions. The result is **unordered**; consumers must sort if comparing.
 - **`domains` is always present in the PUT body** (CLI-1981): `--add-domains`/`--remove-domains` default to a non-nil empty array, so the merge gate is always true from the CLI. With no domain flags (or an explicit empty `--domains=`) the body carries the recomputed existing set; when the provider has no domains it is the literal `"domains":[]`.
 - Metadata URL validation error message: `only HTTPS Metadata URLs are supported Use --skip-url-validation to suppress this error.` (single trailing period; differs from `sso add`'s variant which omits the trailing period).
-- The `## Attribute Mapping` / `## SAML 2.0 Metadata XML` sections are emitted as plain markdown (heading + fence). Visual styling of the headings does not match the old Glamour-rendered output; the table portion and the XML body inside the fence are byte-parity (see `formatSsoMetadataXml`).
+- The `## Attribute Mapping` / `## SAML 2.0 Metadata XML` sections are emitted as plain markdown (heading + fence). The headings carry no extra styling; the XML body inside the fence is formatted by `formatSsoMetadataXml`.
 - **PUT failure message reuses the GET error string**: a non-2xx PUT response produces `unexpected error fetching identity provider: <body>` — note "fetching" not "updating".

A newly un-gated sibling (a path ADR 0021's gate excluded before the write, but not after) is absorbed into the SAME plan, through the SAME skip rules as any other change (an `env()`-sourced sibling is still never overwritten; a `local_only` sibling the remote never reported is still never written) and the SAME warning derivation (a newly-absorbed `dual_scope`/`duplicates_root`/`array_drift` candidate is flagged exactly like a first-round one — the fixpoint's output is classified in ONE pass over the union of every round's changes, not accumulated plan-by-plan). Repeats until a round finds nothing new to project, capped at 4 rounds — die-free: hitting the cap simply stops absorbing further rounds, leaving layer 2 as the actual safety net.
 
-**Layer 2 — schema-validation gate.** Before the pre-write TOCTOU re-read, the projected FINAL document — every surviving planned write, plus a newly-created block's `project_id`, applied to the raw on-disk document shape — is decoded through `@supabase/config`'s real `CliConfigSchema` decode (`decodeCliConfigDocumentForValidationEffect`, `@supabase/config/internal`), with the same `goViperCompat` semantics the next `loadCliConfig` call will apply and its own environment resolution (see below). This composes the SAME env-interpolation → schema-decode steps `loadCliConfigFile` itself runs, minus the raw parse that doesn't apply to an in-memory document. On a decode failure, every planned write under the nearest enclosing family/provider table of each failing path is dropped (walking upward from the failing path for the deepest ancestor declaring an `enabled` key, falling back to the immediate parent) — reported as a NEW skip reason, `would_invalidate`, plus a `would_invalidate` warning naming the still-missing field(s) and, when a missing field's local spelling is itself an unresolved `env(VAR)` reference, the exact variable to set. The document is re-projected and re-validated, capped at 4 rounds; if it still fails once nothing more can be dropped, the whole command fails with a typed, never-user-actionable error (`LegacyConfigPullValidationFailedError`) rather than writing — dropping a family always restores a subtree to its pre-pull state, which loaded successfully at the start of the very same command, so exhausting the cap without success means the drop heuristic missed the right family or something else is structurally broken, not a real user-facing condition.

 Layer 2's validation mirrors the loader's OWN environment resolution exactly — the current process environment layered with the project's `.env`/`.env.local` (`decodeCliConfigDocumentForValidationEffect`, `@supabase/config/internal`), not bare `process.env` — and, for a `[remotes.*]` destination, ALSO decodes the write projected onto the overlay-merged document (the same merge a future `loadCliConfig` targeting that project ref applies before its own checks-enabled decode), since a block's business-rule checks are disabled until it is actually selected and a write can therefore pass unmerged yet still fail once merged. A decode failure whose path ALREADY failed in the raw, pre-write document — checked the same way, before any of this run's writes are projected — is pre-existing: never attributed to this plan, never dropped, never a reason to fail the command, since the file was already in that state and pulling only ever needs to leave it no worse.
