Problem

Fleet identity checks accept only st3/fleet/<fleet>. An authenticated endpoint with fractal/fleet/<fleet> fails those checks even when its fleet and gateway match.

Change

• Centralize exact old/new fleet protocol matching in one allocation-free predicate.
• Use it for the join gateway binding, adapter invite and confirmation bindings, and signed member endpoint validation.
• Preserve existing fleet, member, gateway and sponsor checks. Keep default writers, grants, exposures and dial behavior unchanged.
• Cover both names, wrong fleets and prefixes, persisted TOML spelling, and pairing confirmation. Update replication docs and release notes.
• Persisted settings, generic endpoint routes, status and handshake fields already carry protocol strings unchanged; no new validation or rewriting is added there.

Verification

At b2d3edea461a611b6e4e414b37592560bcee8b6e, through build admission and nix develop:

• cargo test -p smallclaims fleet::: 60 passed, 0 failed. Includes fleet_protocol_names_are_bound_to_the_exact_fleet, advertised_fleet_protocol_names_are_read_without_rewriting_routes, persisted_fleet_protocol_round_trip_preserves_either_name, and pairing_join_writes_configuration_only_after_helper_confirmation (both prefixes).
• cargo test -p fractal-fabric-adapter: 47 passed, 0 failed. Includes endpoint_protocol_accepts_both_names_only_for_this_fleet and unchanged grant/re-key/leave safety tests.
• Before: new-name sponsor bindings fail the exact old-name check. After: old and new names pass for the same fleet; wrong fleets and prefixes remain refused at these identity boundaries.
• Diff: 129 additions and 7 deletions (136 changed lines).
• Disposable Cargo target removed after tests: 1,222,162,944 allocated bytes removed.
• Ambient Cargo initially had no real toolchain on PATH; using the repository Nix shell resolved it. No full workspace suite or formatter was run.

Open questions

No design questions. This is accepting readers only, not dual exposure or a writer switch. PR #3644 overlaps reconcile.rs and reconcile_tests.rs; this PR changes only its protocol check and adds a separate test. No new public capability or readiness checker. Kept draft as requested.

CI scanner repair pushed as a normal commit: 0ac2c1cb2bb9828adfb97ba9f1b019031bc56b6d.

The conservative Rust input scanner treats the protocol prefix literal fractal/fleet/ as a possible path rooted at crates/fractal. No test actually opens that crate. Declared the scan result in .st/rust-test-inputs.json rather than obscuring the protocol constant or changing the scanner.

scripts/rust-test-inputs-scan --check .st/rust-test-inputs.json passed locally (exit 0). The initial 60-second invocation timed out; the completed invocation took 107 seconds. No Cargo target was used or recreated. Product code and earlier test results are unchanged. Total diff is now 140 changed lines.
