e00c899219 cmd, templates, integration: extract shared production constants
Constants the operator/test reader benefits from centralising.
Tests stay verbatim (the .golangci.yaml goconst tune skips them);
extraction here applies only where the same literal acts as
shared vocabulary across files.

  cmd/headscale/cli/strings.go (new)
    Cobra subcommand verbs and aliases shared by every list / show
    / new / delete / expire command across api_key, nodes, policy,
    preauthkeys, users — plus the Result / Created / Expiration
    column headers used in printOutput maps.

  hscontrol/templates/design.go
    cssBorderHS, cssBreakWord, cssCenter, cssOverflowWrap — shared
    styles applied across design.go, ping.go, register_confirm.go.
    spaceS already existed; switch raw "0.5rem" literals to it.

  integration/hsic/hsic.go
    binHeadscale, flagOutput, acceptJSON — names invoked across
    hsic.go and config.go.

  integration/tsic/tsic.go
    tailscaleBin — used across docker exec call sites.

b29ae25356 policy/v2: evaluate the tests block on user-initiated writes
v2 silently dropped policy.tests, so a policy that contradicted its
own assertions still applied. Resolve src/dst via the existing Alias
machinery, walk the compiled global filter rules (acls and grants
both contribute), and run on every user-write boundary: SetPolicy,
the file watcher, and `headscale policy check`. A failing test
rejects the write before it mutates live state.

Boot-time reload skips evaluation; an already-stored policy that
references a deleted user shouldn't lock the server out.

`headscale policy check` is a thin frontend for the new CheckPolicy
gRPC method. The server-side handler builds a fresh PolicyManager
from the request bytes and the state's live users/nodes, runs
SetPolicy on the sandbox so the tests block executes, and returns
the result through gRPC status. No persistence, no policy_mode
coupling. --bypass-grpc-and-access-database-directly opens the DB
directly when the server is not running.

cmd/headscale/cli/root.go no longer special-cases `policy check` in
init() (the early return from PR #2580 broke --config registration
and viper priming for --bypass).

integration/cli_policy_test.go covers policy_mode={file,database} x
fixture={acl-only, acl+passing-tests, acl+failing-tests} x
bypass={false,true} = 12 rows.

Updates #1803

4e0c2b8556 cmd/headscale/cli: validate users in policy check
Add --bypass-grpc-and-access-database-directly to policy check so
the new ambiguous-user validator runs against the live user list.
Without the flag, policy check stays a syntax-only check and the
success message says so.

Updates #3160

0d4f2293ff state: replace zcache with bounded LRU for auth cache
Replace zcache with golang-lru/v2/expirable for both the state auth
cache and the OIDC state cache. Add tuning.register_cache_max_entries
(default 1024) to cap the number of pending registration entries.

Introduce types.RegistrationData to replace caching a full *Node;
only the fields the registration callback path reads are retained.
Remove the dead HSDatabase.regCache field. Drop zgo.at/zcache/v2
from go.mod.

af777f44f4 cmd/headscale/cli: extract bypassDatabase helper and simplify policy file reads
Add bypassDatabase() to consolidate the repeated LoadServerConfig +
NewHeadscaleDatabase pattern in getPolicy and setPolicy.

Replace os.Open + io.ReadAll with os.ReadFile in setPolicy and
checkPolicy, removing the manual file-handle management.

6c08b49d63 cmd/headscale/cli: add confirmAction helper for force/prompt patterns
Centralise the repeated force-flag-check + YesNo-prompt logic into a
single confirmAction(cmd, prompt) helper.  Callers still decide what
to return on decline (error, message, or nil).

7b7b270126 cmd/headscale/cli: add mustMarkRequired helper for init-time flag validation
Replace three inconsistent MarkFlagRequired error-handling styles
(stdlib log.Fatal, zerolog log.Fatal, silently discarded) with a
single mustMarkRequired helper that panics on programmer error.

Also fixes a bug where renameNodeCmd.MarkFlagRequired("new-name")
targeted the wrong command (should be renameUserCmd), making the
--new-name flag effectively never required on "headscale users rename".

095106f498 cmd/headscale/cli: convert remaining commands to RunE
Convert the 10 commands that were still using Run with
ErrorOutput/SuccessOutput or log.Fatal/os.Exit:

- backfillNodeIPsCmd: use grpcRunE-style manual connection with
  error returns; simplify the confirm/force logic
- getPolicy, setPolicy, checkPolicy: replace ErrorOutput with
  fmt.Errorf returns in both the bypass-gRPC and gRPC paths
- serveCmd, configTestCmd: replace log.Fatal with error returns
- mockOidcCmd: replace log.Error+os.Exit with error return
- versionCmd, generatePrivateKeyCmd: replace SuccessOutput with
  printOutput
- dumpConfigCmd: return the error instead of swallowing it

e4fe216e45 cmd/headscale/cli: switch to RunE with grpcRunE and error returns
Rename grpcRun to grpcRunE: the inner closure now returns error
and the wrapper returns a cobra RunE-compatible function.

Change newHeadscaleCLIWithConfig to return an error instead of
calling log.Fatal/os.Exit, making connection failures propagate
through the normal error path.

Add formatOutput (returns error) and printOutput (writes to stdout)
as non-exiting replacements for the old output/SuccessOutput pair.
Extract output format string literals into package-level constants.
Mark the old ErrorOutput, SuccessOutput and output helpers as
deprecated; they remain temporarily for the unconverted commands.

Convert all 22 grpcRunE commands from Run+ErrorOutput+SuccessOutput
to RunE+fmt.Errorf+printOutput. Change usernameAndIDFromFlag to
return an error instead of calling ErrorOutput directly.

Update backfillNodeIPsCmd and policy.go callers of
newHeadscaleCLIWithConfig for the new 5-return signature while
keeping their Run-based pattern for now.

43afeedde2 all: apply golangci-lint 2.9.0 fixes
Fix issues found by the upgraded golangci-lint:
- wsl_v5: add required whitespace in CLI files
- staticcheck SA4006: replace new(var.Field) with &localVar
  pattern since staticcheck does not recognize Go 1.26
  new(value) as a use of the variable
- staticcheck SA5011: use t.Fatal instead of t.Error for
  nil guard checks so execution stops
- unused: remove dead ptrTo helper function

db: use PolicyManager for RequestTags migration
Refactor the RequestTags migration (202601121700-migrate-hostinfo-request-tags)
to use PolicyManager.NodeCanHaveTag() instead of reimplementing tag validation.

Changes:
- NewHeadscaleDatabase now accepts *types.Config to allow migrations
  access to policy configuration
- Add loadPolicyBytes helper to load policy from file or DB based on config
- Add standalone GetPolicy(tx *gorm.DB) for use during migrations
- Replace custom tag validation logic with PolicyManager

Benefits:
- Full HuJSON parsing support (not just JSON)
- Proper group expansion via PolicyManager
- Support for nested tags and autogroups
- Works with both file and database policy modes
- Single source of truth for tag validation

73023c2ec3 all: use immutable node view in read path
This commit changes most of our (*)types.Node to
types.NodeView, which is a readonly version of the
underlying node ensuring that there is no mutations
happening in the read path.

Based on the migration, there didnt seem to be any, but the
idea here is to prevent it in the future and simplify other
new implementations.

reformat code (#2019)
* reformat code

This is mostly an automated change with `make lint`.
I had to manually please golangci-lint in routes_test because of a short
variable name.

* fix start -> strategy which was wrongly corrected by linter
