types.NodeView.TailNode takes a selfPolicyCaps tailcfg.NodeCapMap
parameter and merges it into the baseline. The mapper's WithSelfNode
hands it the policy result via state.NodeCapMap; peer-path callers
pass nil because peer-side CapMap is set downstream via
policyv2.PeerCapMap.
The nodeAttrs compat test now diffs the full TailNode self-view
output against captured SaaS netmaps. Before this change the test
compared compileNodeAttrs alone -- the policy-only output -- and
needed a strip list to compensate for the missing baseline. With
TailNode on the diff path, baseline emission is exercised end-to-end
by every capture; a regression in TailNode breaks the suite.
unmodelledTailnetStateCaps drops cap/ssh and cap/file-sharing now
that both sides emit them identically. The file header is rewritten
to read as 'caps SaaS emits where headscale has no equivalent yet'
rather than the more confusing 'shape divergence' framing.
Adds a data-driven test that loads testdata/nodeattrs_results/*.hujson
and diffs the captured SaaS-rendered netmaps against headscale's
compileNodeAttrs output. Each capture is one scenario the SaaS
control plane has rendered against the same policy headscale is asked
to compile -- the test enforces shape parity per node.
tailnet_state_caps.go enumerates the caps SaaS emits where headscale
has no equivalent concept yet (user-role admin/owner, tailnet lock,
services host, app connectors, internal magicsock and SSH tuning,
tailnet-state metadata) plus the always-on baseline (admin, ssh,
file-sharing) and the taildrive pair. stripUnmodelledTailnetStateCaps
filters both sides of cmp.Diff so the comparison focuses on the
policy-driven caps. PeerCapMap encodes which caps the Tailscale
client reads from the peer view (suggest-exit-node when exit routes
are approved, etc.) for use by the mapper.
testcapture switches to typed tailcfg/netmap/filtertype/apitype
values so schema drift between the capture tool and headscale
becomes a compile error rather than a silent test failure. Existing
compat suites (acl, grants, routes, ssh, issue_3212) move to the
typed shape.
The 53 SelfNode netmap captures and the 7 anonymizer-corrupted
suggest-charmander -> suggest-exit-node restorations in
routes_results / issue_3212 ride along.
