v1.6 Release Roadmap — sequencing, waves & critical path (provisional)

[VijitSingh97]

Single source of truth for the v1.6 release plan — same format as #364. Provisional: small milestone, far out; re-sequence when the cycle opens. Spec-gap assessments from the 2026-07 audit sit on every issue.

The theme: v1.6 loosens where the stack can live. Everything to date assumes the appliance model — one dedicated host, Caddy owning :443, the default subnet. v1.6 makes the documented opt-outs real: co-hosting next to other services (#181), a remote Tari node like Monero's remote mode (#103), and proof the stack actually works off the default subnet (#201).

   #181  co-hosting umbrella ── split into: disable-Caddy mode / alternative-ports
         (Wave 0: split the issue; define the auth-when-Caddy-is-bypassed fail-closed rule)
   #103  remote Tari base node ── Wave 0: feasibility SPIKE first
         (remote --merge-mine over gRPC: templates/submission/latency/auth → go/no-go;
          must define how the #314 socat Tor bridge behaves in remote mode)
   #201  e2e: non-default network.subnet in the live matrix
         (independent; extend to cover post-#346 proxy_net + the #344 onion vhost binding)

Wave 0 — Splits & spikes

• [Feature/Discussion] Support co-hosting via migration guides and relaxed reverse-proxy/network bindings #181 — split the umbrella: part 2 (disable-Caddy / external reverse proxy — decide the bind contract and the "auth must not vanish with Caddy" rule) and part 3 (alternative ports = a Caddyfile listen-port knob, not compose mappings) become their own issues.
• Evaluate a remote Tari base-node option (tari.mode: remote), mirroring Monero remote #103 — feasibility spike: remote merge-mine gRPC go/no-go before any config work. [TODO: verify upstream] items are listed in the gap assessment.

The work

• e2e: deploy a NON-default network.subnet in the live matrix (#180) #201 — e2e: deploy a non-default network.subnet in the live matrix. Already executable as written; one-line scope addition per the gap comment.
• [Feature/Discussion] Support co-hosting via migration guides and relaxed reverse-proxy/network bindings #181 — Co-hosting: migration guides + relaxed reverse-proxy/network bindings (via its split children).
• Evaluate a remote Tari base-node option (tari.mode: remote), mirroring Monero remote #103 — Remote Tari base-node option (tari.mode: remote) — only if the spike says go.

Release status — cycle not open

Gates when it opens: #181 split merged · #103 spike verdict recorded · gouda pass including one co-hosted-profile scenario · CHANGELOG · standard cut process.
