Recording the full mcp-lifecycle fixture against real isolated PHP
(08-09-PLAN.md Task 2) uncovered three byte-level gaps between wristband's
assumed contract and actual production PHP behavior:
- Every explicit "Cache-Control: no-store" PHP sets is actually delivered
as "no-store, private" (Laravel's session-cookie default merges "private"
onto any explicit value); wristband's own default for unheadered JSON
error responses is "no-cache, private" (matching the house convention
already used elsewhere), not empty.
- PHP's redirect responses (authorize success and every error redirect)
render Symfony's default HTML redirect body with Content-Type
"text/html; charset=utf-8"; Go's bare 302 with no body never matched.
wristband/redirect_html.go ports that exact byte template, including
PHP's htmlspecialchars(ENT_QUOTES) escaping (Go's html.EscapeString uses
different quote entities).
tide/normalize.go: isIDKey now also masks "_ids" plural array fields
(e.g. collection_ids), a latent parity-corpus gap no prior fixture had
exercised with a literal, non-empty, non-placeholder array value.
RFC 7591 registration returns a string client_id and unix client_id_issued_at; treating those as Carbon/integer foreign keys would fail PHP self-replay of MCP OAuth.

Album sync payloads hash the collection and stamp a checkpoint that
change across seed runs and must not fail PHP self-replay.

PHP album payloads leave discogs_id null. The id mask required an
integer and failed PHP self-replay on otherwise identical bodies.
