description	Interactively authoring an access-manager permission-declaration manifest (permissions.yaml) for the access-manager "inversão de responsabilidade": drives a plugin team through discovering its real Authorize() surface, normalizing every action to the SEMANTIC standard (never HTTP verbs), declaring roles/group grants and the M2M contract, then emits and validates a manifest that matches the lib-auth/v3 auth/declaration schema. Use when a plugin must publish its own permissions at boot (WireFromEnv) instead of the access-manager seed owning them, or when writing/fixing a permissions.yaml. It also bumps the repo's github-actions-shared-workflows CI pin to the release carrying the permission-manifest nudge. Skip when the plugin has no auth guards, or you only need the wiring (see WireFromEnv) and the manifest already exists.

Declaring Plugin Permissions

Drive a Lerian plugin team through authoring permissions.yaml — the client-side, SEMANTIC declaration the plugin PUBLISHES at boot under the access-manager inversion. This is an interactive workflow: follow the steps in order and use AskUserQuestion to gather every choice. Do not free-hand a manifest.

Overview

Schema authority: lib-auth/v3 auth/declaration/manifest.go (>= v3.4.0-beta.1), mirrored server-side by plugin-access-manager identity/pkg/model/declaration.go. The reconciler validates this exact shape at boot and refuses a bad manifest.

THE CRITICAL INVARIANT: every (resource, action) pair in the manifest MUST exactly match a real AuthClient.Authorize(service, resource, action) guard in the plugin (lib-auth auth/middleware/middleware.go). If they diverge, authz silently breaks — the guard demands a permission the manifest never declared. Adopting the semantic standard therefore means the route guards AND the manifest move together.

• CANONICAL model (semantic, complies): br-sisbajud (internal/auth/declaration/permissions.yaml).
• ANTI-EXAMPLE (HTTP verbs, do NOT copy): midaz-fees — its guards pass Authorize("plugin-fees","estimates","post"). Legacy. Never emit verb actions.

When to use

• A plugin must publish its own permissions at boot (inversion) — authoring a new permissions.yaml.
• Fixing or migrating a plugin whose guards/manifest use HTTP verbs to the semantic standard.

Skip when

• The plugin has no Authorize(...) guards / no RBAC surface.
• Only the wiring is needed and the manifest already exists — point to authdecl.WireFromEnv and stop.

The naming standard (non-negotiable)

The schema doc comment says verbatim: "The action is SEMANTIC (create/read/update/delete), never an HTTP verb."

HTTP verb (FORBIDDEN)	Semantic action (REQUIRED)
post	create
get	read
put / patch	update
delete (method)	delete / remove

Domain verbs are first-class and encouraged where CRUD does not fit: rotate, trigger, justify, generate, reprocess, read_pii, request_read, request_write, receive. Keep them; do not force them into CRUD.

This is ENFORCED, not just advised. post/get/put/patch are rejected by the lib-auth manifest validator at boot AND by the check-manifest-actions CI guard (Step 9). Only delete among HTTP methods is allowed — it is also a valid semantic action. Never emit post/get/put/patch as an action.

Manifest schema (author against THIS)

Top-level YAML: service (str, REQUIRED), version (int, REQUIRED), permissions (list), roles (list), m2m (object). All bare-name rules below: the server composes the prefix — never pre-prefix.

Field	Rule
service	REQUIRED, non-empty, no ./.. segment. KEEP any plugin- prefix. MUST equal the M2M app slug AND DisplayName (BOLA, enforced at boot). Also the 1st arg of Authorize.
version	REQUIRED int >= 1. ADVISORY — excluded from content hash; bumping alone is a no-op publish.
permissions[].resource	REQUIRED, BARE (server composes {service}/).
permissions[].action	REQUIRED, SEMANTIC — never an HTTP verb.
permissions[].effect	allow or deny ONLY.
permissions[].roles	>= 1 BARE role name, each MUST be declared in roles:.
roles[].name	REQUIRED, BARE. / allowed as hierarchy separator (fees/editor).
roles[].granted_to	list of { group: <bare-name> }. GROUP-ONLY — there is no user grantee. Server composes the {owner}/ prefix.
m2m.exposed	bool — this plugin is callable as an M2M target.
m2m.needs	list of target service slugs this plugin CALLS via M2M (e.g. midaz).

Composed names the server builds: permission {service}/{resource}:{action}, role {service}/{name}, group {owner}/{group}.

See template.permissions.yaml in this folder for a compact, valid, commented example.

Interactive workflow — follow in order

Step 1 — Determine service

Grep the plugin for its product/slug constant before asking:

grep -rn -iE "ProductName|ApplicationName|ModuleName|feesApplicationName|Slug\s*=" \
  --include="*.go" <plugin-root> | head

Propose the found constant as the default. Confirm with AskUserQuestion, and warn: it MUST equal the M2M app DisplayName and be the first arg of every Authorize(...) call (BOLA). Keep any plugin- prefix.

Step 2 — Discover the REAL authorization surface

Enumerate what the code actually enforces today:

grep -rn "\.Authorize(" --include="*.go" <plugin-root>

Extract each (service, resource, action) triple from the guard chains (and route tables). Present the full list. This list is ground truth — the manifest must cover exactly these pairs (Step 8 re-checks).

Step 3 — Normalize actions to the SEMANTIC standard

For EACH discovered action:

• If it is an HTTP verb (post/get/put/patch/delete-method) → propose the semantic equivalent from the table AND flag that the route guard must change too (guard + manifest move together — this is a code change, not just YAML).
• If it is already semantic → keep it.
• If CRUD does not fit → offer the relevant domain verb.

Use AskUserQuestion per action/resource to let the engineer confirm or rename, offering sensible options (e.g. for delete: delete vs remove). Record the final semantic (resource, action) set. If any guard currently passes a verb, list those guards explicitly as follow-up code edits the team owns — do not silently emit verb actions to make the mismatch "go away".

Step 4 — Roles and group grants

Ask (via AskUserQuestion):

• Which roles exist? Default viewer + editor; offer domain roles (operator/investigator/compliance-officer/…) as in br-sisbajud.
• Which BARE group(s) grant each role? (Groups are group-only, bare.)
• Grant mapping — offer this DEFAULT, let them override: read/query actions → viewer + editor; mutating actions → editor-only.

Every permission MUST list >= 1 role, and every listed role MUST be declared.

Step 5 — M2M contract

Ask:

• exposed: is this plugin an M2M target (callable by other plugins)?
• needs: which services does it CALL via M2M (e.g. midaz)? Omit the block if neither applies.

Step 6 — Emit permissions.yaml

Write the manifest to the plugin's declaration dir (mirror br-sisbajud: internal/auth/declaration/permissions.yaml). Bare resources/groups/roles, semantic actions, valid effects, >= 1 role per permission. Then show the wiring the plugin adds (manifest authoring is the focus; this is the glue):

//go:embed permissions.yaml
var Manifest []byte

// ...at startup (authdecl = github.com/LerianStudio/lib-auth/v3/auth/declaration, >= v3.4.0-beta.1):
stop, err := authdecl.WireFromEnv(ctx, authdecl.WireInput{
    Slug:     <service>,   // MUST equal manifest.service (BOLA)
    Manifest: Manifest,
    Logger:   logger,
})

Deployment sets the FIXED, un-prefixed env contract (default OFF, fail-open): DECLARATION_ENABLED, PLUGIN_IDENTITY_HOST, M2M_CLIENT_ID, M2M_CLIENT_SECRET, PLUGIN_AUTH_ENABLED, PLUGIN_AUTH_HOST.

Step 7 — Validate

Run structural checks against every rule below, and if a Go toolchain + lib-auth (>= v3.4.0-beta.1) are available, verify against the REAL validator (parse+Validate, zero network) with a tiny throwaway program:

// authdecl "github.com/LerianStudio/lib-auth/v3/auth/declaration"
// _, err := authdecl.New(authdecl.Config{Slug: "<service>", Manifest: raw, /* IdentityAddr, ClientID/Secret dummy */})
// New parses + Validate()s the manifest eagerly and enforces slug==service (BOLA); a
// non-manifest error means the manifest itself is structurally valid.

Or a YAML lint + this checklist. Validation rules (all aggregated at boot):

• service non-empty and not ./...
• version >= 1.
• each action is SEMANTIC: post/get/put/patch are REJECTED at boot (delete is allowed — also a valid semantic action).
• each permission: non-empty resource and action; effect in {allow, deny};

  = 1 role; every role reference is a DECLARED role.

• no duplicate composed permission {service}/{resource}:{action}.
• no duplicate composed role {service}/{name}.
• no Casdoor-safe-name collision: chars / ? : # & % = + ; and whitespace collapse to - (lossy), so two different names can collide — and a name that derives to empty is rejected.

Step 8 — Alignment gate (BLOCKING)

Re-confirm every declared (resource, action) maps to a real Authorize(...) call (Step 2 list) and vice-versa. Enumerate ANY mismatch as blocking:

• guard exists, manifest missing → add the permission.
• manifest declares a pair no guard uses → remove it or add the guard.
• guard still passes an HTTP verb → the team MUST update the guard to the semantic action so both sides use it (do not "fix" it by declaring the verb).

Do not consider the manifest done while any mismatch remains.

Step 9 — Scaffold the durable CI guard (Makefile)

The alignment gate above is a one-time check. Lock the semantic standard in so a future edit that reintroduces an HTTP verb FAILS the build — two layers:

• Boot-time (lib-auth): the manifest validator rejects post/get/put/patch actions at boot — a plugin with an HTTP-verb action won't start. delete stays valid. Automatic once the plugin is on the lib-auth release carrying the rule; nothing to add.
• CI (Makefile): add an earlier, cheaper guard that fails in CI before boot.

Check the plugin's Makefile for the existing check-* convention (most Lerian plugins wire check-tests, check-migrations, … into a ci:/check aggregate — grep ^check- and ^ci:). Add a check-manifest-actions target matching that idiom and wire it into the aggregate:

MANIFEST ?= internal/auth/declaration/permissions.yaml

.PHONY: check-manifest-actions
# Fail if the manifest is missing/unreadable, or if it uses HTTP-verb actions.
# 'delete' is allowed (also a valid semantic action). Mirrors the boot-time
# lib-auth rule. (Pattern assumes block-style `action:` entries — adapt it if
# your manifest uses flow-style, e.g. `- {resource: x, action: post}`.)
check-manifest-actions:
	@test -r "$(MANIFEST)" || { echo "ERROR: manifest not found or unreadable: $(MANIFEST)"; exit 1; }
	@echo "Checking manifest actions are semantic (not HTTP verbs)..."
	@if grep -inE '^[[:space:]]*action:[[:space:]]*["'\'']?(post|get|put|patch)["'\'']?[[:space:]]*$$' "$(MANIFEST)"; then \
		echo "ERROR: HTTP-verb action in $(MANIFEST) — use a SEMANTIC action (create/read/update/delete or a domain verb). 'delete' is allowed."; \
		exit 1; \
	fi
	@echo "OK: manifest actions are semantic."

Add check-manifest-actions to the ci:/check: prerequisite list (and .PHONY). If the plugin has no check-*/ci idiom, still add the target and call it where tests run. Confirm it FAILS on a seeded action: post and PASSES on the real manifest before finishing.

Step 10 — Bump the shared-workflows CI pin

The org shared CI (LerianStudio/github-actions-shared-workflows, reusable go-pr-validation.yml) now carries a NON-BLOCKING permission-manifest-nudge that reminds any lib-auth repo still missing a permissions.yaml. You are already touching this repo — bump its pin so the pipeline is current.

• Find the consumer pins: grep -rn 'LerianStudio/github-actions-shared-workflows' .github/workflows. Expect exact-tag uses: …@vX.Y.Z on go-pr-validation.yml / go-release.yml / routine.yml. Leave any …@v1 major-float pins as-is.
• Resolve the latest release tag: gh release view --repo LerianStudio/github-actions-shared-workflows --json tagName -q .tagName (or gh api repos/LerianStudio/github-actions-shared-workflows/releases/latest -q .tag_name). It must be >= the release that introduced permission-manifest-nudge.
• Bump EVERY exact-tag shared-workflows pin in .github/workflows/*.yml to that tag, keeping all of them on the SAME version. Do not touch unrelated uses: lines.

This is hygiene, not a gate: for THIS repo — which now declares a manifest — the nudge reports "compliant" and posts nothing. The bump only keeps the shared pipeline current. Confirm the target tag exists before writing, and preserve the pin format.

Red Flags — STOP

• An action is post/get/put/patch/delete-the-method → it is an HTTP verb.
• A resource, role, or group carries a {service}/ or {owner}/ prefix → it will double-prefix; write it BARE.
• A granted_to entry has a user: key → there is no user grantee; groups only.
• A permission lists zero roles, or a role not in roles: → validation fails.
• You are emitting a verb action to sidestep a guard mismatch → fix the guard instead.
• service differs from the M2M app DisplayName / the Authorize 1st arg → BOLA break.

All of these mean: stop and correct before writing/finishing the manifest.

Anti-Rationalization

Rationalization	Why it's WRONG	Required action
"The guard passes post, so I'll declare post to match."	Freezes the legacy anti-pattern; the standard is semantic on BOTH sides.	Rename guard AND manifest to the semantic action together.
"I'll pre-prefix the resource with the service to be safe."	Server composes the prefix; you get {service}/{service}/….	Write resources/roles/groups BARE.
"A user grantee would be convenient here."	The schema has no user grantee.	Use a group; grant the group to the role.
"Version bump publishes the new content."	Version is excluded from the content hash — bump alone is a no-op.	Change the actual permissions/roles content.
"The manifest is valid, so we're done."	Structural validity ≠ alignment with real guards.	Pass Step 8; every pair must map to an Authorize call.
