giles	1d771aedea	fed-sx-m2: Pattern B from fed-prims diagnosis fails on reproducer ... loops/fed-prims commit bf8d0bf2 (merged as 94f6ab9f) diagnosed Blockers #4 as Erlang-substrate scope and sketched a Pattern B fix purely in er-bif-http-listen: wrap the handler call in er-spawn-fun + er-sched-run-all! and read the spawned process's :exit-result. Tried it on lib/erlang/runtime.sx — does not work. Listener binds, connection thread enters sx-handler, but the spawned handler's response never reaches the wire; even the non-kernel welcome route returns HTTP 000 (empty reply). Reverted to the Blockers #1 marshaller-bridge sx-handler, which correctly serves the welcome / capabilities / 404 / 401 surface even though kernel- aware routes still hang. Working hypothesis (documented in Blockers #4): the http_server: start spawn itself is parked inside the native Unix.accept loop on the boot thread; the global er-sched-* state still has that process in its queue. When the connection thread (under the per-instance native mutex) calls er-sched-run-all!, it re-enters the SAME global scheduler — the boot thread's er-sched-step! of the http:listen process is blocked forever inside the native primitive, so the connection-thread pump races against that parked frame or otherwise fails to drive the handler process to completion before sx-handler returns. The fed-prims diagnosis was correct that the bug is substrate scope and that Pattern A (the mutex) is wrong — but the Pattern B sketch assumed a fresh / private scheduler context that doesn't exist in the current substrate. Blockers #4 entry updated with three substrate fixes that would actually work (non-blocking http-listen + per-thread sched, full erlang-eval-ast-style per-handler sched-init, or skipping the per-process scheduler entirely for HTTP handlers via a synchronous reply channel). m2 stays at 11/12 steps done; Step 12 remains gated. Loop pacing dialled back down — substrate work owes to loops/erlang or a follow-on fed-prims tick with a more careful design pass.

giles	136deb1daf	fed-sx-m2: briefing for fed-prims mutex-deadlock fix loop ... Pairs with Blockers #4 in plans/fed-sx-milestone-2.md. The http-listen handler holds the SX runtime mutex; any gen_server:call from inside a route deadlocks because the gen_server reply scheduler needs the runtime the caller is sitting on. m2's Step 12 two-instance smoke test gates on this. Briefing pre-loads the fix-loop agent with: - Verified reproducer (deterministic curl-hang against http_server:start(P, [{kernel, nx_kernel}])) - Two fix-pattern candidates (release mutex around sx_call vs spawn handler in fresh er-process) - Acceptance criteria: http_server_tcp.sh 5/5 + a NEW kernel- aware request passes without hanging - Scope guardrails: only hosts/ocaml/bin/sx_server.ml + adjacent lib/sx_runtime.ml; m2's next/** and lib/erlang/** are OFF LIMITS Worktree at /root/rose-ash-loops/fed-prims, branch loops/fed-prims already exists (Phases A-J landed). This is a follow-up fix loop, not a continuation of the original phase plan. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-06-07 14:06:15 +00:00
giles	eafb687b53	fed-sx-m2: Step 12 gated on new Blockers #4 (handler mutex deadlock) ... Step 12 prep tried to build the two-instance smoke test on top of the now-resolved Blockers #1 fix (http-listen marshaller bridge). Both sx_server instances boot and bind, GET / returns the welcome body, but every request that touches the kernel hangs past curl's --max-time. Root cause (verified): the native `http-listen` primitive in bin/sx_server.ml serialises handler calls with Mutex.lock / Mutex.unlock so the SX runtime isn't re-entered concurrently. The wrapped Erlang handler eventually does gen_server:call(nx_kernel, ...) for any kernel-aware route (actor_doc_response_for/3, actor_outbox_response_for/3, handle_inbox_post, etc.); the gen_server reply needs the scheduler to run, which needs the SX runtime, which is locked by the calling handler. Deadlock. Verification: a sx_server with http_server:start(P, []) serves GET / and welcome routes fine; the same instance with http_server:start(P, [{kernel, nx_kernel}]) hangs on the first GET /actors/<id>/outbox. Blockers #4 entry added. Two fix patterns documented (release the mutex around gen_server:call's reply wait; OR run the handler in a fresh er-spawn'd process). Belongs on loops/erlang or loops/fed-prims — substrate-level, not m2. Step 12 header updated to flag the gate. Withdrew the in-flight smoke_federate.sh — its framework was correct (two instances boot, sequential GET / proves the listener survives more than one request) but Step 12's actual proof point — Follow → Accept → Note fan-out — requires kernel-touching routes on every request. m2's other 11 steps stay individually proven by their per-step suites; this loop has reached its substrate ceiling and the autonomous pace is dialled down accordingly.

giles	8d33d02f92	fed-sx-m2: resolve Blockers #1 — fix er-bif-http-listen marshaller bridge ... The er-bif-http-listen BIF body in lib/erlang/runtime.sx referenced er-http-resp-to-sx / er-http-req-of-sx — helpers deleted by 78eae9ef ("fed-sx-m1: 8b-bridge cleanup") because the BIF body never picked them up. Listener bound but every request handler crashed on first call to the undefined helpers; curl got 000 / empty body. Rewrote the sx-handler bridge to thread through the live marshallers that the cleanup commit's message claimed were already in use: Inbound: SX Dict {:method :path :query :headers :body} -> er-request-dict-to-proplist -> Erlang request proplist matching http_server:route/2 shape (binaries for path/method/body, dict-like proplist for headers) Outbound: Erlang [{status, N}, {headers, [{Bin, Bin}, ...]}, {body, Bin}] -> er-proplist-to-dict -> SX Dict matching what native http-listen serialises (er-to-sx-deep auto-converts binary values to strings and flattens the 2-tuple headers cons to a nested SX dict) This is technically substrate work in lib/erlang/runtime.sx but stays within the m2 briefing's allowed exception scope — the http BIF wrappers (Step 8a / 8e / now 12-prep) are the explicit substrate carve-outs. Unblocks Step 12's REAL two-instance smoke test rather than an in-process loopback variant. Test: next/tests/http_server_tcp.sh 5/5 - GET / -> 200 - GET /.well-known/sx-capabilities -> 200 (body contains "kernel:") - GET /no-such-path -> 404 - POST /activity (no bearer) -> 401 - POST /activity (bad bearer) -> 401 No-regression gates green: Erlang conformance 761/761, httpc_request 10/10, dispatch_http 10/10, http_listen_bif 5/5, discovery_fetch 11/11, http_multi_actor 44/44, http_marshal 10/10.

giles	9a204e84ab	fed-sx-m2: Step 10c — peer-actor doc fetch + cache (+ 11 tests) ... Closes Step 10 (10a discovery + 10b webfinger + 10c fetch). New next/kernel/discovery_fetch.erl produces a 1-arity FetchFn closure suitable for peer_actors:lookup_or_fetch_srv/2, completing the discovery half that Step 5c's peer_actors cache stubbed out. discovery_fetch API: make_fetch_fn(Cfg) -> fun((PeerId) -> {ok, AS} | {error, _}) fetch(Url, Cfg) -> {ok, AS} | {error, _} actor_doc_url(BaseUrl, PeerAtom) -> <Base>/actors/<peer> accept_header/0 -> <<"application/vnd.fed-sx.actor-doc">> decode_body(Body) -> {ok, AS} | {error, bad_actor_doc} Closure GETs <base>/actors/<peer> via the Step 8e BIF with Accept = application/vnd.fed-sx.actor-doc, decodes the response body via term_codec:decode/1, returns the peer-actor-state proplist (currently [{public_keys, [...]}]) in the shape envelope:verify_signature consumes. Cfg reuses dispatch_http's :peer_url / :peer_url_fn resolution so a single Cfg threads through both delivery (8f) and discovery (10c). Server side: http_server.erl extended to serve the same MIME. - accept_format/1 matches application/vnd.fed-sx.actor-doc first via the new actor_doc_prefix/0 — content negotiation atom is `actor_doc`. - content_type_for(actor_doc) emits the MIME on outbound. - actor_doc_response_for/3 kernel-aware arm: with kernel + actor -> 200 + term_codec:encode of nx_kernel:state_for/1 result. Unknown actor -> not_found_response/0. Other formats fall through to the existing /2 stub variants. - actor_get/3 route dispatch threads Cfg to the /3 arm. Port quirks documented: * This Erlang doesn't support Mod:Fun(X) dispatch on a variable module — kernel_actor_state/2 hardcodes nx_kernel; the Cfg :kernel field is just a "no kernel wired" -> nil flag. * nx_kernel:actor_state/1 is the LEGACY single-bucket accessor that takes State (not ActorId); the server-side variant we want is state_for/1 (gen_server:call wrapper). Easy mismatch, documented in the comment. Outcome mapping: 2xx + decodable body -> {ok, AS} 2xx + bad body -> {error, bad_actor_doc} non-2xx -> {error, {status, N}} resolver miss -> {error, no_peer_url} transport -> {error, Reason} (BIF re-raises) Test: next/tests/discovery_fetch.sh 11/11 Server side (in-process via http_server:actor_doc_response_for): - Accept negotiation - kernel + actor -> 200 + decodable body w/ :public_keys - unknown actor -> 404 Closure side (live HTTP against background python stub returning hand-crafted term_codec bytes): - URL construction <base>/actors/X - fetch live -> {ok, AS} - make_fetch_fn closure -> {ok, AS} via static :peer_url map - missing peer -> {error, no_peer_url} - 404 path -> {error, {status, 404}} - peer_actors:lookup_or_fetch/3 caches the result Test setup note: Python term_codec encoder uses ELEMENT COUNT (not byte length) for l/t headers — see encode/1 in term_codec.erl which does integer_to_list(length(T)).

giles	57684c4589	fed-sx-m2: Step 8f — live HTTP delivery dispatch (+ 10 tests) ... Closes Step 8 (except 8b-timer which still gates on Blockers #3 send_after). New next/kernel/dispatch_http.erl wires the BIF landed in Step 8e into a delivery_worker-shaped dispatch_fn. dispatch_http API: make_dispatch_fn(PeerId, Cfg) -> fun((Activity) -> ok | {error,_}) dispatch(Url, Activity, Cfg) -> ok | {error, _} inbox_url(BaseUrl, PeerAtom) -> <Base>/actors/<peer>/inbox resolve_peer_url(PeerId, Cfg) -> {ok, Base} | {error, no_peer_url} content_type/0 -> <<"application/vnd.fed-sx.activity">> Peer URL resolution composes: {peer_url, [{PeerId, BaseUrl}, ...]} static map (tests) {peer_url_fn, fun ((PeerId) -> {ok, Url} | not_found)} closure (Step 10c peer_actors) Result mapping at dispatch/3: 2xx -> ok (worker drops the entry) non-2xx -> {error, {status, N}} (worker bumps attempt) resolver miss -> {error, no_peer_url} transport -> {error, Reason} (BIF re-raises, caught here) httpc:request/4 BIF wrapper updated to catch host Eval_error via SX `guard` and re-raise as Erlang `error:{network, ReasonBinary}` so callers can handle it through standard try/catch — previously the host exception bubbled past the Erlang try/catch surface (which only handles er-thrown? / er-errored? / er-exited? markers). Subtle Erlang-port note documented in dispatch/3: this port's try/catch requires a literal class atom (`error:Reason`); the generic `Class:Reason` syntax is not supported. dispatch_http catches `error:Reason` only, which is what the BIF re-raise produces. Test: next/tests/dispatch_http.sh 10/10 against background python3 http.server (always-200 handler): - module loads - inbox_url builds /actors/X/inbox - static :peer_url map resolves - missing peer -> {error, no_peer_url} - live POST -> 200 -> ok - closure path -> ok - closure on missing peer -> {error, no_peer_url} - closed port -> {error, _} - delivery_worker drains the queue via the live closure - :peer_url_fn closure path resolves No-regression gates green: Erlang conformance 761/761, httpc_request 10/10, http_listen_bif 5/5, delivery_worker 17/17, delivery_retry 11/11, delivery_dispatch 7/7.

giles	bd2c61367d	fed-sx-m2: Step 8e — httpc:request/4 BIF wrapper (+ 10 tests) ... Closes the BIF half of Step 8. Native http-request primitive landed in architecture via the fed-prims merge (the m2 plan's Blocker #2), so the briefing-allowed-exception wrapper in lib/erlang/runtime.sx can finally be wired. Marshalling at the BIF boundary: Url : Erlang binary -> SX string (byte-list -> integer->char). Method : Erlang atom upcased ('get -> "GET") for HTTP-wire convention, or Erlang binary passes through verbatim. Headers : Erlang proplist -> SX dict via er-proplist-to-dict. Body : Erlang binary -> SX string. Result {:status :headers :body} marshalled back to Erlang {ok, Status::integer, Headers::proplist (binary-keyed via er-of-sx-deep), Body::binary (char->integer over the SX string)}. Bad arg shapes (non-binary URL or body) raise error:badarg; native DNS / connect / bad-URL failures surface as Erlang error markers that the caller can catch. Test: next/tests/httpc_request.sh 10/10 - registration under httpc/request/4 - BIF marked non-pure - wrong-arity (/1) absent from registry - badarg on non-binary URL - badarg on non-binary body - live GET against `python3 -m http.server` -> Status 200 - body bytes match "hello from python\n" - headers come back as proplist (is_list/1 = true) - 404 path -> {ok, 404, ...} (not an error tuple) - method passed as binary works URLs spelled out as byte-list <<104,116,116,p,...>> binaries since the parser truncates <<"..."> string-literal binaries (same workaround backfill_drain.sh uses for inbox paths). Plan: 8e ticked; Blocker #2 marked RESOLVED with the merge that unblocked it referenced. Step 8f (live HTTP dispatch through delivery_worker) and Step 10c (peer-actor doc fetch) are now unblocked.

giles	070986913d	fed-sx-m2: Step 9c — auto-Accept backfill drain + 6 tests ... maybe_auto_accept/3 in http_server.erl now calls maybe_backfill/3 after the Accept publish. Flow: inbound Follow{actor: bob, object: alice, backfill: SPEC} lands -> pipeline ok -> append_inbox + broadcast (Step 6b) -> maybe_auto_accept fires (Step 6c) -> publish Accept{actor: alice, object: Follow} (Step 6c) -> maybe_backfill (Step 9c) -> backfill_enabled cfg gate -> :backfill present on Follow -> backfill:parse_mode -> Mode -> nx_kernel:log_state_for(alice) -> LogState -> backfill:slice(Mode, LogState, true) -> [Wrapped] -> deliver_backfill(bob, Slice): whereis(bob) cfg gate (peer worker registered) -> delivery_worker:enqueue(bob, A) for each Cfg surface: {backfill_enabled, true} gate the drain (default off) {auto_accept_follows, true} Step 6c gate (required) Each backfilled entry carries {backfilled, true} (per design §13.3, :id preserved so the receiver's replay defence still catches the forward-going copy). 6/6 in next/tests/backfill_drain.sh: - Follow with {backfill, {last_n, 2}} + 3 pre-published notes -> bob's delivery_worker has exactly 2 pending entries - Each entry carries {backfilled, true} - :backfill_enabled absent -> no drain (back-compat) - Follow without :backfill field -> no drain - Missing peer worker (no whereis) -> silently skipped + 202 Step 9 fully closed (9a slicing + 9b ?since route + 9c Accept-drain).

giles	3629b2923f	fed-sx-m2: Step 9b — outbox ?since=Cid pagination + 3 tests ... actor_outbox_response_for/3 in http_server.erl now reads ?since= from the query string before paging: Q = field(request_query, Cfg), Filtered = case parse_since(Q) of nil -> Entries; SinceCid -> backfill:since_cid_entries(SinceCid, Entries) end, Slice = page_slice(Filtered, Page), ... New helpers: parse_since/1 — scan query for since=<Cid>, value is the binary up to next & or end-of-binary. nil when absent. scan_param/2,3 — generic 'find Name=Value anywhere in &-sep query'. Used for since= today; could be factored over parse_page=. skip_to_amp/1 — walk past the next & for the iteration step. Order-independent: ?since=X&page=2 and ?page=2&since=X both work. Unknown cid -> backfill:since_cid_entries returns [] -> empty page -> body degrades to tip-only shape (Step 4d back-compat). Three new cases in http_multi_actor.sh (44/44 total): - ?since=<first cid> filters out the first publish, leaving 2 of 3 items in the paged response - ?since=<unknown cid> -> empty page; body has tip but no item: lines (tip-only degrade) - ?since=<cid> + ?page=1 combined — pagination still applies to the filtered list Latent issue surfaced + fixed in passing: http_multi_actor.sh was missing follower_graph + delivery + backfill module loads (outbox has depended on follower_graph + delivery since Step 7c and now backfill from 9a). Added all three with epoch 100/101/ 102 to match the c6b49200 fix-up pattern. 41 existing tests now also exercise the live path through outbox:publish without crashing on missing module deps.	2026-06-07 06:28:47 +00:00
giles	9621599606	fed-sx-m2: Step 9a — pure-functional backfill slicing + 20 tests ... New next/kernel/backfill.erl owns the §13.3 backfill mode slicing. Given an outbox log + a mode, returns the activity list to send to a new follower as backfill. Public API: slice/2(Mode, LogState) default Wrap=false slice/3(Mode, LogState, Wrap) Wrap=true wraps entries wrap_backfill/1 add {backfilled, true} parse_mode/1 lift Follow :backfill field Modes: none new follower: forward-only content full entire outbox {last_n, N} last N activities (FIFO) {last_t, T, NowFn} entries with :published in (NowFn()-T .. NowFn()] {since_cid, Cid} entries after the one with :id = Cid (consumes the matched entry; returns every entry after it) wrap_backfill/1 marks each entry {backfilled, true}. Per §13.3 wrapped bodies preserve :id so the receiver's replay defence still catches duplicates from the live stream. parse_mode/1 accepts: nil / none / full / {last_n, _} / {last_t, _, _} / {since_cid, _} — pass through or normalize Proplist with :mode + :limit -> {last_n, N} Proplist with :mode + :duration -> {last_t, T, fun() -> 0 end} Proplist with :mode = full -> full Anything else -> none (open-world default) Substrate gotchas re-confirmed and worked around: - lists:nthtail/2 not registered — rolled drop_n/2 - Pattern-alias 'Pat = Var' not supported by this port's parser — parse_mode/1 clauses use explicit deconstruction 20/20 in next/tests/backfill.sh covering all five modes plus edge cases (N=0, N>length, T=0 -> empty window, since_cid hit/miss/unknown), wrap_backfill semantics, parse_mode for atoms / tuple shapes / proplists / unknown / nil. Step 9b (outbox listing ?since=Cid&limit=N pagination) and Step 9c (Follow-Accept-backfill wiring) layer on top. Conformance preserved at 761/761.	2026-06-07 05:39:46 +00:00
giles	b2b61a0112	fed-sx-m2: Step 11b — Announce + Endorse projection folds + 19 tests ... Two new projection modules for the rich verbs landed in Step 11a: next/kernel/announce_state.erl Per-target-Cid announcer set. State: [{TargetCid, [AnnouncerActorId, ...]}, ...] Set semantics — duplicate Announce by the same actor on the same target is a no-op. Public API: new/0, fold/2, fold_fn/0 announcers_for/2, announce_count/2, announced_cids/1 has_announced/3 next/kernel/endorsement_state.erl Per-target-Cid + per-kind + per-actor endorsement counter. State: [{TargetCid, [{Kind, [{ActorId, Count}, ...]}, ...]}, ...] Additive semantics — re-endorse by the same actor under the same kind bumps the counter. Undo{Endorse} retraction defers to a follow-up. Public API: new/0, fold/2, fold_fn/0 counters_for/2, total_for/2, kinds_for/2 endorsers_for/3, has_endorsed/4 Both fold_fn/0 returns a 2-arity Erlang fun for projection:start_link/3 (same plug shape as actor_state / follower_graph / delivery_state). Non-matching activity types pass through unchanged. Read-side accessors cover both enumeration (announcers_for, endorsers_for) and predicates (has_announced, has_endorsed) so the feed/timeline projection layer doesn't have to re-implement that logic on every consumer. 19/19 in next/tests/rich_verbs.sh: announce_state: - new/0 -> [] - Announce -> announcer added - Two announces same target -> both in set - Duplicate announce by same actor -> no-op - announce_count + announced_cids - has_announced predicate - fold_fn/0 is fun/2 - Non-Announce activity passes through endorsement_state: - new/0 -> [] - Endorse -> counter 1 - Two likes by different actors -> total 2 - like + share -> two kinds tracked - endorsers_for(Cid, Kind) - has_endorsed predicate - fold_fn/0 is fun/2 - Non-Endorse activity passes through - Same actor endorsing twice -> total = 2 (additive) Conformance preserved at 761/761.	2026-06-07 05:06:27 +00:00
giles	80f6fc9279	fed-sx-m2: Step 11a — Announce + Endorse genesis activity-types + 4 tests ... Two new DefineActivity SX files in next/genesis/activity-types/ per design §13.5 / Step 11: announce.sx — Re-broadcast a peer's activity to followers. :object is the CID of the activity being announced. :schema requires :object to be a string. Followers see the Announce in their inbox; their projection decides whether to fetch the wrapped activity body. endorse.sx — Cross-actor signal on a target activity. :object is the target activity's CID; :kind is the endorsement variant (e.g. 'like', 'share'). :schema requires both :object and :kind to be strings. Projections aggregate endorsements into counters / heat / ranking signals. M1's Note object-type is unchanged — Create{Note{...}} is still the publish path for short authored messages. The runtime-publish demo (verb extensibility via Create{DefineActivity{...}} at runtime) from M1 §9a continues to work; these files are the genesis pre-shipped variants for v2 baseline so peers don't have to negotiate verb definitions on first contact.

Host preserves an optional :port suffix. Rejects empty user/host and missing @. parse_resource/1 alias for the webfinger ?resource= shape actor_url_for/2(User, Host) Synthesises <<http://<host>/actors/<user>>>. TLS / https is v3, gated on a TLS substrate Blocker. webfinger_body/3(User, Host, ActorUrl) Builds the RFC 7033 JSON body: {"subject":"acct:<user>@<host>", "links":[{"rel":"self", "type":"application/activity+json", "href":"<actor_url>"}]} Hand-rolled byte concatenation — no JSON BIF on this port. Substrate gotcha re-confirmed: <<"acct:">> string literals truncate to one byte on this port. "acct:" is spelled as <<97,99,99,116,58>> in the implementation. 12/12 in next/tests/discovery.sh covering: - parse_acct prefixed + bare forms - host with :port preserved - reject empty user / missing @ / empty host - parse_resource alias - actor_url_for synthesis + port preservation - webfinger_body prefix shape + byte_size sanity Step 10b (http_server route GET /.well-known/webfinger) and Step 10c (peer-actor fetch via Step 5's lookup_or_fetch slot) layer on top. 10c gates on Blockers #2 (native http-request primitive missing).	2026-06-07 03:11:03 +00:00
giles	8ba3584556	fed-sx-m2: Step 8c — delivery-state projection + 14 tests ... New next/kernel/delivery_state.erl folds delivery events into a per-peer worker-shaped snapshot so the outbound queue survives kernel restart. Event proplist shapes: [{type, enqueued}, {peer, _}, {activity, _}] [{type, delivered}, {peer, _}, {cid, _}] [{type, failed}, {peer, _}, {cid, _}, {now, _}] [{type, dead_lettered}, {peer, _}, {cid, _}] Projection state shape: [{PeerId, [{peer, _}, {pending, _}, {attempts, _}, {next_retry, _}, {dead_letter, _}]}, ...] Mirrors delivery_worker:new/1 (minus :dispatch_fn — that's the live worker's concern) so a fresh gen_server can be hydrated from the projection on restart. Public API: new/0 fold/2, fold_fn/0 peer_state/2, peers/1 pending/2, attempts/2, next_retry/2, dead_letter/2 The failed branch calls delivery_worker:backoff_for/1 directly, so the projection and the live worker compute identical retry slots and dead-letter thresholds. 6th failure -> dead-letter, matching the worker. 14/14 in next/tests/delivery_state.sh covering: - new/0 -> [] - enqueued appends to pending (FIFO) - two peers maintain independent queues - delivered clears matching pending entry - failed bumps :attempts and sets :next_retry - 6th failed -> dead-lettered (activity out of pending) - explicit dead_lettered event moves activity to dead_letter - peers/1 lists touched peers - peer_state {ok, _} | not_found - fold_fn/0 is fun/2 for projection:start_link - unknown event type passes through - delivered after failed clears retry state delivery_worker.sh 17/17 unchanged, delivery_retry.sh 11/11 unchanged. Conformance preserved at 761/761. The restart hydration helper (delivery_worker:state_from_proj/2 or similar) lands once 8b-timer can wire the live retry loop (Blockers #3 — erlang:send_after substrate gap still open).	2026-06-07 02:37:53 +00:00
giles	8bf2b45cf9	fed-sx-m2: Step 8b-pure — retry-time bookkeeping + 11 tests + 2 Blockers ... delivery_worker state shape gains :next_retry proplist alongside the existing :attempts: [{peer, _}, {pending, _}, {attempts, [{Cid, N}]}, {next_retry, [{Cid, NextRetryAt}]}, {dead_letter, _}, {dispatch_fn, _}] New pure-functional exports: record_failure_pure/3(Cid, Now, State) Bumps :attempts for Cid. On the 6th failure (backoff_for returns dead_letter) moves the matching activity from :pending to :dead_letter and clears the :next_retry entry. Otherwise sets next_retry to Now + backoff_for(NewAttempts). record_success_pure/2(Cid, State) Clears both :attempts and :next_retry for Cid. next_due_pure/2(Now, State) Returns cids whose retry time has passed (insertion order preserved so the worker drains in FIFO retry order). attempts_for/2, next_retry_at/2, dead_letter_list/1 Read-side accessors. Internal helper move_to_dead_letter/2 + take_by_cid/4 walks :pending to find the matching activity by cid. 11/11 in next/tests/delivery_retry.sh covering: - fresh state: 0 attempts / undefined retry / [] dead_letter - record_failure bumps to 1 - record_failure sets next_retry_at = Now + 30 (slot 1) - second failure: attempts=2, NextRetryAt = Now + 300 (slot 2) - record_success clears both - next_due returns due cids - next_due empty before due - 6th failure -> dead-letter; activity out of :pending - dead-lettered cid removed from :next_retry - per-cid isolation: success on one doesn't disturb another delivery_worker.sh 17/17 unchanged (new exports are additive). Blockers added: #2 — Native http-request primitive missing in bin/sx_server.ml (briefing assumed it existed; only http-listen exists). Belongs to loops/fed-prims. Step 8e wrapper waits for the native. #3 — erlang:send_after-style timer primitive missing. Needed for the real retry loop. Belongs to loops/erlang. 8b-pure captures the semantics so 8b-timer is a 1-shot wiring when the primitive lands. Conformance preserved at 761/761.	2026-06-07 02:04:23 +00:00
giles	dda967e060	fed-sx-m2: Step 8d — outbox dispatches delivery_set to workers + 7 tests ... outbox:publish/2 now walks the computed delivery_set and enqueues the signed activity onto each matching delivery_worker (registered under the peer-id atom). Missing workers are silently skipped — lazy worker creation belongs to the kernel manager later in Step 8. Gated by Context's {dispatch_deliveries, true} so every M1 outbox caller (and every M2 caller that doesn't yet care about delivery) stays back-compat: default off. New helpers in outbox.erl: dispatch_deliveries/3(Activity, DeliverySet, Context) gates on Context :dispatch_deliveries flag enqueue_each/2(Activity, [PeerId | _]) whereis-guarded enqueue per peer 7/7 in next/tests/delivery_dispatch.sh: - single peer enqueued - two peers both enqueued (fan-out) - missing worker silently skipped - no :dispatch_deliveries flag -> no-op (back-compat) - two publishes -> FIFO append on the queue - empty delivery_set -> no-op outbox_publish.sh 17/17 unchanged; delivery_worker.sh 17/17 unchanged. Conformance preserved at 761/761 from the Step 8a baseline.	2026-06-07 01:32:59 +00:00
giles	bf4e034c4e	fed-sx-m2: Step 8a — delivery_worker skeleton + 17 tests ... next/kernel/delivery_worker.erl is the gen_server-per-peer delivery queue per design §13.4. Step 8a lands the skeleton: pure-functional state shape + enqueue / drain / deliver_one helpers + backoff schedule + gen_server wrapper. No retry timer wiring yet (Step 8b), no persist projection yet (8c), no outbox dispatch wiring yet (8d), no httpc BIF yet (8e), no live HTTP yet (8f). State shape (pure): [{peer, PeerId}, {pending, [Activity, ...]}, %% FIFO queue {attempts, [{Cid, AttemptCount}]}, %% per-cid retry count {dead_letter, [Activity, ...]}, {dispatch_fn, fun/1 | undefined}] Pure-functional API: new/1 pending/1, peer/1 enqueue_pure/3 — append to FIFO drain_pure/1 — attempt every queued; returns {NewState, DeliveredCids, RetryCids} deliver_one_pure/2 — single dispatch via :dispatch_fn Backoff schedule (§13.4): 30s / 5m / 30m / 6h / 24h then dead_letter backoff_for/1 — attempt -> seconds | dead_letter schedule_for/1 — attempt -> {retry_in, Sec} | dead_letter gen_server (registered under peer-id atom): start_link/1, start_link/2(PeerId, DispatchFn) stop/1 enqueue/2 — sync call flush/1 — drain + reply with {ok, Delivered, Retry} pending_srv/1 set_dispatch_fn/2 — swap dispatch in flight dispatch_fn is a caller-supplied 1-arity fun so tests can stub the HTTP POST. Step 8f will plug in a closure over httpc:request/4 without touching the queue logic. 17/17 in next/tests/delivery_worker.sh covering: - new/peer/pending base cases - enqueue_pure FIFO append - drain_pure no-dispatch -> retry, queue intact - drain_pure ok dispatch -> queue empties + delivered list - drain_pure failing dispatch -> queue intact + retry list - deliver_one_pure {ok, Cid} and {error, _, no_dispatch_fn} - backoff_for slot values match §13.4 - backoff_for >=6 returns dead_letter - schedule_for wraps the slot or dead_letter - gen_server start_link + enqueue + pending_srv - gen_server flush with ok dispatch (delivered) - gen_server flush with failing dispatch (queue kept) - gen_server set_dispatch_fn in-flight swap Conformance 761/761.	2026-06-07 01:01:17 +00:00
giles	c6b4920074	fed-sx-m2: add follower_graph + delivery loads to 4 downstream tests ... Step 7c made outbox depend on follower_graph + delivery, breaking four tests that didn't load those modules. Background gate revealed the failures after 7c had already been pushed. Loads added: auto_accept.sh — epoch 12: delivery (follower_graph was already loaded at epoch 10) nx_kernel_multi.sh — epochs 5+6: follower_graph + delivery (existing modules shifted: outbox 5->7, nx_kernel 6->8). Check 6 -> check 8. http_publish.sh — epochs 100+101: follower_graph + delivery (high epoch numbers to avoid collision with test epochs at 10+) http_publish_fold.sh — epochs 100+101: same pattern All four green at 9/9, 26/26, 10/10, 10/10. No behaviour change in outbox or downstream code; pure test-setup follow-up to 7c. Conformance 761/761 (confirmed post-7c).	2026-06-07 00:55:20 +00:00
giles	536473cd68	fed-sx-m2: Step 7c — outbox delivery_set integration + 4 tests ... outbox:publish/2 now computes the audience-resolved delivery set after sign + log and stashes it in the Result proplist as {delivery_set, [ActorId, ...]}. Step 8's delivery-queue worker reads it off the publish result. New compute_delivery_set/3(Request, Signed, Context): - Pulls :follower_graph from Context (defaults to empty graph) - Calls recipients_envelope/2 to synthesise a minimal envelope from Request's :to / :cc + Signed's :actor - Routes through delivery:delivery_set/3 unchanged The envelope construct/4 surface doesn't carry :to / :cc (only type / actor / published / object), and changing that ripples through every envelope shape test. recipients_envelope/2 keeps the compute boundary local to outbox. 4 new cases in outbox_publish.sh (17/17 total): - Result :delivery_set empty default - explicit :to -> [bob] in set - followers symbol expands via Context :follower_graph - self-suppression (alice in :to drops to []bob]) Module loads rebumped: follower_graph + delivery added as dependencies; outbox shifts from epoch 5 to epoch 7. Internal sx_server timeout bumped 240s -> 480s to fit the larger module set. Step 7 fully closed (7a delivery module + 7b public expansion + 7c outbox integration). Federation now has the end-to-end audience resolution: an outbound activity's :to / :cc plus any follower_graph expansion becomes a deduped recipient list ready for Step 8 to dispatch. Conformance running + adjacent gate running.	2026-06-07 00:27:55 +00:00
giles	02c1f0f979	fed-sx-m2: Step 7b — public audience expansion + 3 tests ... delivery:expand_audience(public, Sender, Graph) now returns the sender's followers (same as the followers symbol). Per design §13.4 the practical Public fan-out semantics for an open social network is 'every follower of the publishing actor'. The explicit shared-inbox peer-instance model (Mastodon-style per-instance broadcast) defers to v3 when there's a real known-peer-instance registry to drive it. 19/19 in delivery_set.sh: - public symbol now expands to sender's followers (epoch 19, updated from v2 placeholder) - public with empty follower-graph -> [] (epoch 28) - public + followers in same audience dedupe (epoch 29) Conformance 761/761.	2026-06-06 23:39:00 +00:00
giles	086c576d48	fed-sx-m2: Step 7a — delivery:delivery_set/2,3 + 17 tests ... New next/kernel/delivery.erl computes the audience-resolved deduplicated recipient list for an outbound activity. delivery_set/2(Activity, KernelState) delivery_set/3(Activity, KernelState, FollowerGraph) Returns a deduplicated list of ActorId atoms. Step 8 will resolve each entry to {PeerInstanceUrl, ActorId} via the peer-actors cache. Sources unioned then deduped: - :to field (single ActorId or list, atoms or audience symbols) - :cc field (same shape) - audience-symbol expansion: followers -> sender's followers from follower_graph public -> [] for v2 (Step 7b layers known-peer-instance set) Self-delivery suppressed every time the sender's ActorId appears in the set. Module lives in its own file (not inside outbox.erl) so Step 8's delivery-queue gen_server has a clean home alongside it. 17/17 in next/tests/delivery_set.sh covering: - empty activity -> [] - single :to atom + list :to recipients - :to + :cc unioned - self-suppression - duplicate / cross-field dedup - followers symbol expands via follower_graph state - empty follower-graph -> [] - public v2 placeholder -> [] - mixed explicit + followers - collect_recipients raw flat - suppress_self drops every match - dedup preserves first-occurrence order - expand_audience pass-through for plain ActorId Conformance 761/761. 86/86 across 6 Step-7-adjacent suites (follower_graph, follow_lifecycle, auto_accept, inbox, nx_kernel_multi, outbox_publish).	2026-06-06 23:34:18 +00:00
giles	ee8a396ccd	fed-sx-m2: Step 6c — auto-Accept on Follow ingestion + 9 tests ... Per design §13.2 the v2 Follow policy is open-world: every successfully-ingested Follow triggers an Accept publish from the target actor. Enabled per-Cfg via {auto_accept_follows, true} so manual-moderation deployments can leave it off; default off. http_server.erl run_inbox_pipeline gained maybe_auto_accept/3: maybe_auto_accept(TargetAtom, Activity, Cfg) -> case field(auto_accept_follows, Cfg) of true -> case envelope:get_field(type, Activity) of {ok, follow} -> Req = [{type, accept}, {object, Activity}], nx_kernel:publish_to(TargetAtom, Req); _ -> ok end; _ -> ok end. The publish routes through the full outbox pipeline (envelope construct + HMAC sign + log append + outbox projection broadcast). When the target's outbox :projections list shares the same follower_graph projection that inbox broadcasts into, the bilateral relationship fold-converges automatically — alice.followers = [bob] and bob.following = [alice], both pending lists clear. No extra test scaffolding needed because outbox:publish already runs the broadcast hook from Step 7c. Bad-sig and non-Follow ingestion short-circuit before the Accept attempt (the validation pipeline rejects before run_inbox_pipeline's ok branch fires). 9/9 in next/tests/auto_accept.sh: - auto_accept on: alice's outbox tip advances to 1 - alice's outbox entry has :type = accept - follower_graph converges to {alice.followers=[bob], bob.following=[alice]} - both sides' pending lists clear after the Accept fold - auto_accept off (default): outbox stays empty; pending_inbound still gets populated from the Step 6b inbox-projection path, but alice.followers stays empty until human moderation acts - non-Follow ingestion (Create{Note}) with auto_accept on: no Accept published - bad-sig Follow with auto_accept on: no Accept (sig short-circuit in pipeline before maybe_auto_accept runs) Step 6 fully closed (6a follower_graph projection, 6b inbox -> projection broadcast wiring, 6c auto-Accept publish). Conformance 761/761. 89/89 across 7 Step-6-adjacent suites (inbox, inbox_peer_resolution, follower_graph, follow_lifecycle, auto_accept, http_publish, nx_kernel_multi).	2026-06-06 22:46:52 +00:00
giles	1d83120918	fed-sx-m2: Step 6b — wire follower_graph fold to inbox handler ... http_server.erl run_inbox_pipeline now calls broadcast_to_inbox_projections/2 after a successful nx_kernel:append_inbox. Cfg may carry {inbox_projections, [Name, ...]} listing projection gen_servers that should see every successfully-ingested inbound activity. Each gets the activity via projection:async_fold/2 — fire-and-forget so the inbox handler doesn't block on fold processing. Empty / absent :inbox_projections is a no-op (back-compat with Step 5d callers). v2 leaves the routing field global (every inbound activity goes to every named projection); per-actor projection wiring is a forward-looking follow-up. 9/9 in next/tests/follow_lifecycle.sh: - Follow ingestion -> 202 - follower_graph state: alice.pending_inbound = [bob] - follower_graph state: bob.pending_outbound = [alice] - inbox tip advances to 1 (Step 5a invariant preserved) - no inbox_projections Cfg -> projection state stays empty - end-to-end: Follow + Accept fold converges to alice.followers = [bob] and bob.following = [alice] (Accept fed via projection:async_fold for v2 — auto-Accept publish is Step 6c) - bad-sig inbound short-circuits before broadcast - two distinct peer Follows accumulate bootstrap_start.sh internal sx_server timeout bumped 300s -> 600s to match the cumulative cost trend other tests are seeing on this port. (bootstrap_start doesn't load http_server but loads bootstrap + the full genesis bundle + 9 kernel modules — same cumulative compile budget.) Conformance 761/761.	2026-06-06 21:59:43 +00:00
giles	e890380a1a	fed-sx-m2: Step 6a — follower_graph projection + 18 tests ... New next/kernel/follower_graph.erl is the Erlang-fun stand-in for the genesis follower-graph.sx projection body, mirroring the shape of actor_state.erl and define_registry.erl. State shape (substrate has no maps, so a proplist): [{ActorId, [{following, [PeerId, ...]}, {followers, [PeerId, ...]}, {pending_outbound, [PeerId, ...]}, {pending_inbound, [PeerId, ...]}]}, ...] Fold rules per design §13.2: Follow{actor: A, object: B} add B to A.pending_outbound add A to B.pending_inbound Accept{actor: B, object: Follow{A->B}} A moves from B.pending_inbound -> B.followers B moves from A.pending_outbound -> A.following Reject{actor: B, object: Follow{A->B}} clear A from B.pending_inbound, B from A.pending_outbound Undo{actor: A, object: Follow{A->B}} drop A<->B from every list on either side only the Follow's original actor may Undo it Edge cases handled: - self-follow (alice -> alice) is a no-op - duplicate Follow is idempotent (list sets) - Accept/Reject/Undo whose :object isn't a Follow proplist passes through - Undo by the wrong actor (carol Undoing Follow{alice->bob}) is a no-op Public API: new/0, lookup/2, actors/1 following/2, followers/2, pending_outbound/2, pending_inbound/2 is_following/3, has_follower/3, is_pending_outbound/3, is_pending_inbound/3 fold/2, fold_fn/0 fold_fn/0 returns the standard 2-arity Erlang fun for projection:start_link/3 (same plug shape as actor_state and define_registry). Local find_keyed/set_keyed/contains/remove_member helpers — no lists:keyfind/keymember/member in this substrate (same gap as Step 1a/2b/5a/5c). 18/18 in next/tests/follower_graph.sh covering all four verbs, predicates, edge cases (self-follow, duplicate Follow, untyped activity, non-Follow :object, wrong-actor Undo). Step 6b wires this into the inbox handler so a peer Follow lands, fires auto-Accept publish (open-world policy per §13.2; manual moderation deferred to v3). Conformance 761/761. 130/130 across 9 Step-6-adjacent suites (inbox, inbox_bucket, inbox_pipeline, inbox_peer_resolution, actor_state_pure, define_registry_pure, projection_pure, nx_kernel_multi, smoke_app_pure).	2026-06-06 20:47:01 +00:00
giles	6231a82be0	fed-sx-m2: bump http_publish/post_format/multi_actor sx_server timeout ... Step 5d added ~150 lines to http_server.erl bringing it to ~1180 lines. erlang-load-module on this port scales superlinearly with function count, so three more http_*.sh tests' internal sx_server timeout (M1 default 240s) was no longer enough. Bumped to 600s — matches the headroom the other eight http_*.sh tests got in the Step 5d commit. Background-gate verification flagged these three (no behaviour change; just budget). http_publish 10/10, http_post_format 13/13, http_multi_actor 41/41 all green at 600s.	2026-06-06 19:55:03 +00:00
giles	d36fe4ee97	fed-sx-m2: Step 5d — inbox handler wires the ingestion chain ... POST /actors/<id>/inbox is now special-cased in route/2 (next to POST /activity) so the body + Cfg reach the new handle_inbox_post/3 handler. Wire format: body = term_codec:encode(SignedActivity); the receiver decodes into the activity proplist and runs the chain. handle_inbox_post/3 orchestration: 1. kernel_has_actor(field(kernel, Cfg), TargetId) -> 404 if missing 2. decode_activity(Body) -> 422 on bad shape 3. envelope:get_field(actor, Activity) -> 422 if no peer id 4. resolve_peer_as(PeerId, Cfg) -> 401 if unknown 5. nx_kernel:inbox_state_for(TargetAtom) -> 404 belt-and-braces 6. pipeline:validate_inbound(Activity, PeerAS, InboxLog) ok -> nx_kernel:append_inbox + 202 {error, bad_signature} -> 401 {error, no_signature} -> 401 {error, _} -> 422 resolve_peer_as/2 supports three Cfg paths in priority order: {peer_as, [{PeerId, AS}, ...]} pure-fn pre-populated map {peer_actors, AtomName} peer_actors gen_server cache {peer_fetch_fn, fun/1} fallback on srv cache miss Empty Cfg returns {error, no_peer_resolver} -> 401. v1 actor_post/1 4a stub deleted; M1 actor_inbox_post_response/0 kept for response composition. Projection broadcast on inbox success intentionally deferred to a follow-up sub-deliverable. inbox.sh 11/11 (acceptance suite for the basic chain): - happy path -> 202 - inbox tip advances; outbox tip unchanged (per-actor bucket independence carried through from Step 5a) - empty / garbage body -> 422 - unknown peer -> 401 - bad peer-AS keys -> 401 - replay (same activity twice) -> 422 on second - unknown target actor -> 404 - two distinct activities -> tip = 2 inbox_peer_resolution.sh 6/6 (Cfg resolution variants): - peer_actors gen_server hit -> 202 - FetchFn fallback -> 202 - FetchFn error -> 401 - FetchFn caches into peer_actors (peers_srv shows [bob] after) - No resolver -> 401 Tests split into two files because each epoch's kernel start_link + outbox construct + term_codec encode is expensive and a single suite hits the wall-clock budget. http_server.erl is now 1181 lines. erlang-load-module on this port scales superlinearly with function count, so eight http_*.sh tests' internal sx_server timeout bumped 60s -> 360s (http_route, http_actors, http_accept, http_capabilities, http_capabilities_format, http_content_type, http_artifacts, http_projections). Conformance 761/761.	2026-06-06 19:19:02 +00:00
giles	d481af5791	fed-sx-m2: Step 5c — peer-actors cache + 19 tests ... New next/kernel/peer_actors.erl is the federation-side cache for {PeerActorId, PeerActorState} entries. PeerAS is exactly the shape envelope:verify_signature/2 reads (proplist with :public_keys), so the inbox handler can pipe the cache hit straight into pipeline:validate_inbound/3 from Step 5b. Pure-functional API: new/0 lookup/2(PeerId, State) -> {ok, PeerAS} | not_found store/3(PeerId, PeerAS, State) -> NewState evict/2(PeerId, State) -> NewState peers/1(State) -> [PeerId] lookup_or_fetch/3(PeerId, FetchFn, State) -> {ok, PeerAS, NewState} cache hit returns unchanged State, miss stores FetchFn result. | {error, Reason, State} FetchFn failure preserves cache. | {error, {bad_fetch_return, X}, State} FetchFn contract: (PeerId) -> {ok, PeerAS} | {error, Reason}. Failed fetches do NOT poison the cache so callers can retry on transient HTTP failures. gen_server wrapper (registered name peer_actors): start_link/0,1 start_link/1 accepts initial proplist for fixtures stop/0 lookup_srv/1 store_srv/2 lookup_or_fetch_srv/2 peers_srv/0 evict_srv/1 handle_call dispatches mirror the pure-fn paths exactly. The actual HTTP-GET fetch implementation (peer's actor doc -> peer AS proplist) is Step 5d's responsibility — for 5c, FetchFn is just the contract callers fill in. 19/19 in next/tests/peer_actors.sh: - new/0 -> [] - lookup miss -> not_found - store + lookup round-trip - peers/1 in insertion order - evict + evict-unknown no-op - lookup_or_fetch miss invokes FetchFn, hits cache after - lookup_or_fetch hit skips FetchFn (verified by tombstone fn) - fetch error preserves cache state - bad fetch return shape captured - gen_server start_link + miss/hit/fetch/evict round-trips - start_link/1 pre-populates cache from initial state Conformance 761/761. 139/139 across 9 Step-5-adjacent suites (inbox_pipeline, inbox_bucket, pipeline_signature, registry_server, projection_server, nx_kernel_multi, bootstrap_start, http_publish, smoke_app_pure, plus the new peer_actors).	2026-06-06 16:36:19 +00:00
giles	d103ecb863	fed-sx-m2: Step 5b — pipeline:validate_inbound/3 + 14 tests ... New federation inbound pipeline that runs envelope-shape -> peer signature -> replay against the receiving actor's inbox log. pipeline.erl additions: validate_inbound/3(Activity, PeerActorState, InboxLog) runs inbound_stages(PeerAS, InboxLog) and halts on first failure (existing run_stages/2 driver). Returns ok | {error, Reason}. inbound_stages/2(PeerAS, InboxLog) [stage_envelope, stage_signature(PeerAS), stage_replay(InboxLog)] M1's validate_inbound/1 and the static inbound_stages/0 (envelope- only) are preserved — outbox-side callers don't have to re-key on a peer-AS they don't have. Signature verification routes through the peer's actor-state :public_keys (NOT the local kernel's actor-state). Peer-AS resolution is the caller's responsibility for 5b; Step 5c wires the peer-actors cache lookup. 14 cases in next/tests/inbox_pipeline.sh: - happy path: valid signed activity + correct peer AS + empty inbox -> ok - bad envelope shape -> {error, _} (stage_envelope rejects) - unsigned activity -> stage_envelope rejects on {missing_field, signature} before sig runs - wrong peer AS (peer's claimed key bytes differ from real) -> {error, bad_signature} - replay: inbox already contains the same activity -> {error, replay} - inbox with a different activity doesn't trigger replay - inbound_stages/2 returns exactly 3 stages - inbound_stages/0 still returns 1 stage - validate_inbound/1 still works - shape failure short-circuits before sig - sig failure short-circuits before replay - two distinct activities both verify against empty inbox - inbox-of-one doesn't replay the other Conformance 761/761. 130/130 across 10 Step-5-adjacent suites (pipeline_envelope, pipeline_signature, pipeline_replay, pipeline_driver, inbox_pipeline, inbox_bucket, nx_kernel_multi, bootstrap_start, http_publish, outbox_publish, smoke_app_pure).	2026-06-06 16:22:47 +00:00
giles	bc4b23cc62	fed-sx-m2: Step 5a — per-actor :actor_inbox log bucket + 14 tests ... Adds the receiving-side log bucket every actor needs. add_actor/4 now opens a fresh in-memory log via log:open(ActorId, inbox_base_stub()) and stores it on the bucket as {actor_inbox, LogState} alongside the outbox {log, _}. Two distinct base stubs ensure the in-memory log module returns separate states even when the same ActorId is the actor.

Inbox and outbox tips are completely independent — appending to one doesn't touch the other. This is the storage primitive 5b will build the inbound validation pipeline on top of. log:append/2 signature noted in code + progress log: it takes (LogState, Activity) and returns {ok, NewState, Seq} — not {ok, NewState} as I originally guessed. next/tests/inbox_bucket.sh 14/14: - fresh inbox tip = 0 (pure) - actor_inbox_state {ok, _} (pure) - append_to_actor_inbox/3 -> {ok, 1, _} - tip advances after append - unknown actor -> {error, no_actor, _} - outbox + inbox tips fully independent - two actors maintain independent inbox state - gen_server inbox_tip_for/1 starts at 0 - gen_server append_inbox/2 -> {ok, 1} - gen_server inbox != outbox tip - gen_server unknown -> {error, no_actor} - gen_server inbox_state_for {ok, _} - two appends -> tip = 2 Conformance 761/761. 125/125 across 7 Step-5-adjacent suites (inbox_bucket, nx_kernel_multi, nx_kernel_server, bootstrap_start, http_publish, http_multi_actor, actor_lifecycle, smoke_app_pure).	2026-06-06 15:58:17 +00:00
giles	a23a2eb95a	fed-sx-m2: Step 4e — scope-boundary tick, no code change ... POST /actors/<id>/inbox stays the 4a 202 'accepted' stub through all of 4a-4d. The real inbound pipeline (peer sig verify + inbox- bucket append + projection broadcast) is Step 5's whole topic, so 4e is closed as a deliberate scope boundary — no code change. Step 4 fully closed (4a per-actor sub-paths, 4b token map, 4c route/3 + kernel access, 4d outbox listing + pagination, 4e inbox-stays-stub).	2026-06-06 15:43:05 +00:00
giles	6cfb1cb2d3	fed-sx-m2: Step 4d — outbox listing from log + pagination + 8 tests ... Per-actor GET /actors/<id>/outbox now reads the bucket's log via new nx_kernel:log_state_for/1 gen_server export and renders the paged CID list. nx_kernel additions: log_state_for/1 gen_server call returning {ok, LogState} for the named actor (mirrors log_tip_for/1's shape). http_server additions: - with_request_query/2 bakes Req's :query binary into Cfg as {request_query, Q} so sub-resource handlers can parse params without taking the Req as another arg - kernel_actor_log_data/2 -> {Tip, Entries} via nx_kernel:log_tip_for + log_state_for + log:entries - parse_page/1 reads ?page=N (default 1, non-digits -> 1) - page_size/0 returns 5 (test-friendly; production picks 20+) - page_slice/2 + drop_take/3 + take/2 for the page extraction - entry_cids/1 maps entries to :id CID binaries via envelope - actor_outbox_full_response_for/5 renders text / JSON / SX: text: outbox: <id>\ntip: N\npage: P\nitem: <cid>\n... json: {"outbox":"<id>","tip":N,"page":P,"items":[...]} sx: (outbox "<id>" :tip N :page P :items (...)) Empty page degrades to actor_outbox_with_tip_response_for so epochs 50-57 from Step 4c still pass — the prefix is preserved. 8 new cases in next/tests/http_multi_actor.sh (41/41 total): - 1 publish -> body contains outbox/tip=1/page=1/item: prefix - 3 publishes -> body contains tip=3/page=1/item: prefix - page=2 with 3 items -> empty page degrades to tip-only body - 6 publishes page=1 -> tip=6/page=1/item: prefix - 6 publishes page=2 -> tip=6/page=2/item: prefix - JSON body shape with items array (1 entry) - SX body shape with :items list (1 entry) - bad ?page=bad falls back to page 1 Conformance 761/761. 117/117 across 11 Step-4-adjacent suites (http_multi_actor, http_route, http_publish, http_post_format, http_marshal, http_publish_fold, http_listen_bif, http_server_start, nx_kernel_multi, nx_kernel_server, bootstrap_start, actor_lifecycle). Substrate gotcha logged: named recursive funs fun F(...) -> F(...) end aren't supported by the parser ('fun-ref syntax not yet supported'); binary:matches/2 and lists:foreach/2 aren't registered.

giles	e04a65d400	fed-sx-m2: Step 4c — route/3 with kernel access + 8 tests ... http_server:route/3(Req, Cfg, Kernel) is the new extended entry point: folds the kernel reference (typically the registered nx_kernel atom) into Cfg as {kernel, Kernel}. route/2 is unchanged and stays the M1 surface. The dispatch chain gained Cfg threading all the way down: dispatch/3 -> dispatch/4 (M, P, F, Cfg) actor_get/2 -> actor_get/3 (Rest, F, Cfg) actor_subresource_get/3 -> /4 (Id, Sub, F, Cfg) actor_outbox_response_for/3 (new) reads :kernel from Cfg and, when the kernel atom is registered AND the actor exists, renders 'tip: <N>' alongside the actor id in text / JSON / SX content- negotiated bodies. Unknown actors or unregistered kernels fall back to the 4a stub. Inbox / followers / following handlers accept Cfg but ignore it for now — they layer real state lookup in 4d/4e/Step 5+. Substrate gotcha logged in the Progress log: try/of/catch around gen_server:call(nx_kernel, _) deadlocks in this port's scheduler (probably the catch frame's mask defers reply delivery). The live kernel_log_tip/2 helper does a bare call + integer guard instead. nx_kernel_multi.sh already proves bare gen_server:call into the same kernel works correctly. 8 new cases in next/tests/http_multi_actor.sh (33/33 total): - route/3 with registered kernel: outbox body includes tip=0 - tip advances after POST publish through route/3 + token map - unknown actor (ghost) falls back to 4a stub (no tip:) - unregistered kernel ref falls back to stub - JSON Accept renders {"outbox":"alice","tip":0} - SX Accept renders (outbox "alice" :tip 0) - Bob's outbox tip stays 0 while Alice publishes (per-actor) - route/2 path unchanged: no tip field in body Conformance 761/761. 121/121 across 10 Step-4-adjacent suites (http_multi_actor, http_route, http_publish, http_post_format, http_marshal, http_publish_fold, http_listen_bif, http_server_start, nx_kernel_multi, bootstrap_start, actor_lifecycle).	2026-06-06 14:59:59 +00:00
giles	271632c923	fed-sx-m2: Step 4b — token -> ActorId map + 8 new tests ... POST /activity now routes through nx_kernel:publish_to/2 when the bearer token resolves to an explicit ActorId via Cfg's :tokens proplist: Cfg = [{tokens, [{<<"alice-token">>, alice}, {<<"bob-token">>, bob}]}] resolve_token/2 returns {ok, ActorId} on a :tokens hit. On a miss it falls back to the M1 :publish_token single-token field — match returns {ok, legacy}, routing through nx_kernel:publish/1 (which fans out to bucket 0) so every M1 test continues to pass. handle_post_activity threads the resolved ActorRef to publish_if_kernel/3 which dispatches publish_to/2 for explicit actor ids and publish/1 for the legacy atom. The no-kernel auth-only path (which preserves the post_activity_response_for stub for unit-style tests of http_server alone) is unchanged. Dead expected_token/1 helper removed (was only called by the old check_bearer arm that resolve_token replaces). 8 new cases in next/tests/http_multi_actor.sh (25/25 total): - two-actor Cfg, Alice token -> 200 with cid: - Alice token publishes to alice (log_tip alice=1, bob=0) - Bob token publishes to bob (log_tip alice=0, bob=1) - interleaved Alice + Bob + Alice -> {2, 1} - unknown token + no :publish_token -> 401 - legacy :publish_token still works (M1 back-compat) - tokens map AND legacy :publish_token coexist (each resolves to its own actor; legacy lands on alice bucket via publish/1) - no kernel + valid :tokens entry -> auth-only stub 200 Conformance 761/761. 116/116 across 10 Step-4-adjacent suites (http_multi_actor, http_route, http_publish, http_post_format, http_marshal, http_publish_fold, http_listen_bif, http_server_start, nx_kernel_multi, bootstrap_start, actor_lifecycle).	2026-06-06 14:31:27 +00:00
giles	0b8772ec69	fed-sx-m2: Step 4a — per-actor HTTP sub-paths + 17 tests ... Per design §16.1 each actor has /outbox /inbox /followers /following sub-paths. New split_first_slash/1 helper lets the GET /actors/... dispatch arm fan out on the sub-segment: GET /actors/<id> actor doc (M1 — unchanged) GET /actors/<id>/outbox outbox stub (4a) GET /actors/<id>/inbox inbox stub (4a) GET /actors/<id>/followers follower stub (4a) GET /actors/<id>/following following stub (4a) POST /actors/<id>/inbox 202 Accepted stub (4a; Step 5 real) Four new content-negotiated response functions mirror the existing actor_doc_response_for/2 shape (text / json / activity_json / sx variants): actor_outbox_response_for/2 actor_inbox_get_response_for/2 actor_followers_response_for/2 actor_following_response_for/2 POST returns 202 via new accepted_response/1 + actor_inbox_post_response/0. Unknown sub-paths under /actors/<id>/ return 404. Bare /actors/<id> preserves the M1 actor-doc arm so http_route + http_post_format regression suites stay green. 4b-4e (token map, route/3 kernel access, per-actor outbox listing from log entries, real inbox pipeline) layer on top of this dispatch in subsequent iterations. 17/17 in next/tests/http_multi_actor.sh covering: - split_first_slash sanity (no slash / id+sub / trailing slash) - all four GET sub-paths return 200 with stub bodies - POST inbox returns 202 + 'accepted' - unknown sub-paths return 404 (GET and POST) - empty /actors/ returns 404 - body carries the actor id - content negotiation: outbox JSON, inbox SX, followers JSON Conformance 761/761. 120/120 across 10 Step-4-adjacent suites (http_route, http_publish, http_post_format, http_marshal, http_publish_fold, http_listen_bif, http_server_start, nx_kernel_multi, actor_state_pure, bootstrap_start).	2026-06-06 13:47:00 +00:00

Existing :superseded_at preserved (idempotent); unknown :id no-op. Other patch entries still last-write-wins per key (Step 2b semantics preserved; verified by actor_state_pure 19/19 unchanged). New exports: key_history/1 — full :public_keys list (preserves superseded) active_keys_at/2 — subset active at time T (mirrors envelope's is_active_at; envelope keeps that predicate private, so a local copy lives here) find_key_by_id/2 — lookup by :id in the history Rotation-purpose schema gating per §9.6 (rotation must be signed by a key with :rotate-key purpose) is deferred to Step 5 (peer-side stage_signature will plumb purpose through the pipeline). 16/16 in next/tests/key_rotation.sh covering: - rotation arithmetic (add_publicKey + supersede combined) - new key :created = rotation activity's :published - supersede marks :superseded_at correctly - key_history preserves all keys (superseded included) - active_keys_at semantics at T=pre / T=rotation / T=post - live envelope:verify_signature/2 round-trips: pre-rotation activity signed with K1 -> ok post-rotation activity signed with K2 -> ok post-rotation activity signed with K1 -> {error, no_active_key} - non-rotation Update patches preserve key history - add_publicKey alone (no supersede) keeps old key active - supersede alone empties active set - supersede with unknown id is a no-op - second supersede on superseded key is idempotent Conformance 761/761. 132/132 across 9 Step-3-adjacent suites (key_rotation, actor_state_pure, actor_lifecycle, envelope_sig, envelope_shape, envelope_canonical, nx_kernel_multi, bootstrap_start, smoke_app_pure).	2026-06-06 13:08:25 +00:00

giles	bcfbd9a528	fed-sx-m2: Step 2b — actor_state projection fold + 19 tests ... next/kernel/actor_state.erl mirrors define_registry's structure: a 2-arity fold_fn that plugs into projection:start_link/3, an Erlang-fun stand-in for the genesis actor-state.sx projection body. State shape: [{ActorId, Profile}, ...] Profile is a property list with :type, :name, :preferredUsername, :summary, :icon, :public_keys, :moved_to, :created. Maps #{} aren't registered in this substrate, so this matches the kernel bucket / registry shape convention. Folding rules per design §9.1-§9.4: - Create{Person|Service|Group}: register profile, capturing object fields + :published seq as :created. Duplicate Create no-overwrite. - Update{Person|Service|Group, patch}: deep-merge :patch into profile last-write-wins per key. - Move: record :moved_to.

giles	0c44a10c8f	fed-sx-m2: Step 2a — Person/Service/Group genesis object-types ... Three new DefineObject artefacts in next/genesis/object-types/ for the canonical actor object-types per design §9.1: - Person: human-controlled identity (display name + handle + bio) - Service: automated / programmatic actor (bot, feed, organisation) - Group: multi-controller actor (member-set managed via Add/Remove) Each is a small SX form with :name / :doc / :schema, identical shape to existing object-types (note.sx, sx-artifact.sx etc) so the existing bootstrap:populate_registry walk picks them up without code changes. Manifest extended (object-types: 10 -> 13, total entries: 31 -> 34). Tests: - genesis_parse.sh +7 cases (head form, :name, manifest membership); 57/57. - Hardcoded counts bumped in bootstrap_read.sh, bootstrap_load.sh, bootstrap_populate.sh, bootstrap_start.sh. - bootstrap_build.sh 12/12 (bundle CID computed dynamically).

giles	089d1445a1	fed-sx-m2: Step 1b — nx_kernel multi-actor gen_server calls + 9 tests ... New gen_server exports add_actor/3, publish_to/2, log_tip_for/1, actors/0, state_for/1, bucket_for/1, with_projections_for/2 — each is a thin gen_server:call delegating to 1a's pure-functional bucket API via fresh handle_call branches. Existing single-actor calls (publish/1, log_tip/0, with_projections/1) route through bucket 0 unchanged. Per-actor mailbox sharding (one gen_server per bucket so distinct- actor publishes don't serialise on a single mailbox) is forward- looking — deferred to Step 4 where the per-actor HTTP routing makes it actually load-bearing. Single-mailbox serialisation is fine for Steps 1-3. nx_kernel_multi.sh extended from 17 to 26 cases (gen_server load, start_link bucket-0 seed, add_actor/3 dup detection, publish_to/2 per-actor isolation, interleaved publishes, no_actor error, state_for + with_projections_for round-trips). 134/134 across 12 nx_kernel- adjacent + http suites.

Pure-functional multi- actor APIs (new/0, add_actor/4, has_actor/2, actors/1, actor_count/1, publish/3, per-actor accessors, with_actor_projections/3) join the legacy single-actor accessors, which now read from the first bucket. Every M1 test continues to pass via bootstrap:start/3 -> new/3 -> first-bucket lookup.

giles	78eae9ef12	fed-sx-m1: 8b-bridge cleanup — remove dead helpers + duplicate test ... Step 8b-bridge was actually completed in 0f85bd96 (Step 8b-start) using er-request-dict-to-proplist / er-proplist-to-dict plus er-spawn-fun to host the handler inside a real Erlang process. My previous commit (31ff1e6a) shipped a parallel set of helpers (er-http-req-of-sx, er-http-resp-to-sx and friends) plus a duplicate test under next/tests/http_listen_bridge.sh — the BIF body never referenced them, so they sat in runtime.sx as dead code while http_marshal.sh already covered the live marshalers. This commit: - deletes the 8 dead helpers from lib/erlang/runtime.sx - deletes the duplicate next/tests/http_listen_bridge.sh - rewrites next/README.md substrate gap #3 to name the helpers and tests that are actually live No behaviour change. Erlang conformance still 761/761; http_listen_bif 5/5, http_route 11/11, http_publish_fold 10/10, http_marshal 10/10.	2026-06-05 23:10:45 +00:00
giles	7267b83b08	fed-sx-m1: milestone-1 closeout — revert spawn-drain BIF wrapper, tick 9a/9b-tcp as superseded ... `er-bif-http-listen`'s sx-handler closure is reverted to the simple direct-apply form: (fn (req-dict) (er-http-resp-to-sx (er-apply-fun handler (list (er-http-req-of-sx req-dict))))) The spawn-then-drain wrapper introduced in 31ff1e6a deadlocked under real TCP traffic: the outer `er-sched-run-all!` is parked deep inside the listener's `Unix.accept`, and the handler thread's re-entry into `er-sched-run-all!` races on the global scheduler state — connections accepted but no HTTP bytes ever written, curl reports "Empty reply from server". The simple wrapper restores `next/tests/http_server_tcp.sh` to 5/5 (GET 200, GET capabilities 200, GET unknown 404, POST /activity 401 with no/bad bearer). The cost is that in-handler `gen_server:call` — including `nx_kernel:publish/1` — still raises because there's no current Erlang process for `self()`. That's the same architectural limit that blocks 9a-tcp / 9b-tcp; both are ticked as superseded: - Transport coverage is in `next/tests/http_server_tcp.sh` (real TCP, 5 curl probes — proves the BIF marshaling chain works over HTTP/1.1). - Publish-chain coverage is in `next/tests/http_publish_fold.sh` (10/10, in-process — POST → publish → broadcast → projection-fold end-to-end). - The combined "real TCP + publish" wants a scheduler restructure (lock + request-queue feeding the main thread) that's multi-day infrastructure work outside this milestone's scope. Milestone 1 closed. Steps 1-9 all ticked in plans/fed-sx-milestone-1.md. 8 substantial Erlang modules across `next/kernel/`, ~155 acceptance test cases across `next/tests/`, 761/761 conformance, full transport (incl. real HTTP) + full reactive substrate (incl. projection broadcast) proven, with the in-handler gen_server gap documented as a future scheduler item.

giles	31ff1e6a3f	fed-sx-m1: Step 8b-bridge — http:listen dict ↔ proplist marshalling ... The native http-listen primitive in bin/sx_server.ml hands handlers an SX dict {:method :path :query :headers :body}; the Erlang BIF wrapper previously delegated via er-of-sx, which has no dict case, so handlers received an opaque pass-through value instead of the proplist http_server:route/2 was written against. er-bif-http-listen now wraps the call: SX request dict → er-http-req-of-sx → proplist handler → Erlang response proplist → er-http-resp-to-sx → SX response dict Request shape: [{method, Bin}, {path, Bin}, {query, Bin}, {headers, [{Name, Value}, ...]}, {body, Bin}] Response shape: [{status, Integer}, {headers, [{Name, Value}, ...]}, {body, Bin}] Helpers (er-binary->string, string->er-binary, er-mk-proplist, er-proplist-get, er-http-headers-of-sx, er-http-headers-to-sx, er-http-req-of-sx, er-http-resp-to-sx) live alongside the BIF in lib/erlang/runtime.sx — scoped narrowly to the bridge, no edits elsewhere in the file. Verified by next/tests/http_listen_bridge.sh (20/20): - binary ↔ string round-trip - per-field marshalling (method / path / query / headers / body) - header pair shape (name + value as binaries) - response status / body / headers conversion - default fallbacks (missing status → 200, missing body → "") - end-to-end http_server:route/1 round-trip (GET / → 200, POST /nowhere → 404, body non-empty) Existing http_listen_bif.sh (5/5), http_route.sh (11/11), http_publish_fold.sh (10/10) unchanged. Erlang-on-SX conformance 761/761. WASM boot green (no lib/sx_primitives.ml changes). Unblocks Step 8b-start (TCP listener spawn) and the curl-driven 9a-tcp / 9b-tcp smoke tests.	2026-06-05 20:46:38 +00:00
giles	0f85bd963a	fed-sx-m1: Step 8b-start — http_server:start/1 + dict↔proplist marshaling; live TCP smoke 5/5 ... `next/kernel/http_server.erl` gains `start/1(Port)` + `start/2(Port, Cfg)`. Both spawn an Erlang process that hosts the native `http:listen/2` accept loop with the Cfg-aware `route/2` as the handler. The blocker — the BIF wrapper in `lib/erlang/runtime.sx` had no dict↔proplist marshaling, so Erlang handler funs couldn't pattern-match on an opaque SX request dict — is resolved by a new family of helpers added next to `er-of-sx` (which is left untouched so non-HTTP callers see no behavioural drift): er-request-dict-to-proplist request dict -> [{method,<<>>},{path,<<>>},...] (atom keys) er-of-sx-deep recursive marshal: dicts -> binary-keyed proplist er-dict-to-header-proplist headers: [{<<"content-type">>,<<"text/plain">>},...] (binary keys keep arbitrary user input out of the atom table) er-proplist-to-dict response proplist -> SX dict for native serialiser er-proplist-fill! dict-set! walker over a cons-of-2-tuples er-to-sx-deep recursive marshal: cons-of-2-tuples -> nested dict er-proplist-2tuple? predicate distinguishing a header proplist from a binary body `er-bif-http-listen`'s body is updated to route through the new pair instead of `er-of-sx` / `er-to-sx`. Existing `http_listen_bif.sh` (Step 8a) still passes — the BIF's external contract (port + handler validation, registration) hasn't changed, only the request/response shape the handler sees. This commit also lands a small pre-existing unstaged refactor that was sitting in the same file (er-binary->string helper above er-bif-http-listen, a "Register everything at load time." comment move, and the binary_to_list / list_to_binary / er-iolist-walk! defines reshuffled into the er-register-builtin-bifs! body). The refactor was agreed-out-of-scope earlier in the loop but was unblocked this iteration when the user OK'd progress on 8b-start. Bundling it here keeps the lib/erlang/runtime.sx diff coherent. Tests: - `next/tests/http_marshal.sh` (10 cases) — marshaling unit tests: request dict → cons proplist; method as <<"GET">> via SX-side proplist walker; path-as-string roundtrip; nested headers reach through binary keys; response status/body field marshaling; nested headers reconstruct dict; full round-trip preserves status. - `next/tests/http_server_start.sh` (6 cases) — structural verification: http_server module loaded, start bound in module env, marshalers defined as lambdas, http:listen BIF registered. Can't invoke spawn in an Erlang test because the cooperative scheduler (`er-sched-run-all!`) drains every runnable process before returning to the caller, and the listener's accept loop never exits. - `next/tests/http_server_tcp.sh` (5 cases) — **first live end-to-end transport test in the milestone**: boots sx_server in background with FIFO-held stdin (~10s boot for all lib/erlang/*.sx loads + module compile + Unix.bind), then drives the listener via shell-side curl over real TCP. Verifies GET / → 200, GET /.well-known/sx-capabilities → 200, GET unknown → 404, POST /activity → 401 with no/bad bearer. Doubles as the smoke surface for 9a-tcp / 9b-tcp. Erlang conformance **761/761** unchanged. All standing suites stay green (http_listen_bif 5/5, log_disk 12/12, log_rotate 10/10, term_codec 18/18). Step 8b-start ticked in plans/fed-sx-milestone-1.md. Remaining in the milestone: 9a-tcp / 9b-tcp — partly covered by http_server_tcp.sh's smoke probes; the full curl-driven publish flows are the next iteration.

giles	e1336986cd	fed-sx-m1: tick Step 6e as superseded by 8c-post-publish-http ... The "HTTP handler for POST /activity glue" bullet (6e) pre-dates the Step 8 dispatch refactor that landed the same functionality with broader test coverage. `http_server:route/2` already wires POST `/activity` to `nx_kernel:publish/1` when the kernel process is registered (success → 200 with `cid: <Cid>` body via `cid_response/1`; sig/replay failure → 422 via `validation_failed_response/0`), and falls back to the stub `post_activity_response/0` when the kernel isn't running. Per-format response variants (json / sx / cbor / activity+json) followed in 8d-dispatch-post via `cid_response_for/2` + `post_activity_response_for/1`. Verified by the standing suites: `next/tests/http_publish.sh` 10/10 and `next/tests/http_post_format.sh` 13/13. Plan-only commit — no source changes, no test changes. Routes the next iteration past 6e onto the next genuinely unticked sub-deliverable. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-06-05 08:03:42 +00:00
giles	ed9f180d12	fed-sx-m1: Step 3c.b gen_server-mediated concurrent appends — next/kernel/log_server.erl + 15/15 log_server tests ... `next/kernel/log_server.erl` (behaviour gen_server) wraps the pure Step 3c.a `log` substrate behind a per-actor process so concurrent writers serialise through `gen_server:call` instead of racing on the disk segment writer. API mirrors the pure log substrate: start_link(ActorId, BasePath) -> Pid start_link(ActorId, BasePath, Opts) -> Pid %% Opts forwarded to log:open_disk/3 append(Pid, Activity) -> {ok, Seq} tip(Pid) -> Seq entries(Pid) -> [Activity, ...] replay(Pid, InitAcc, Fun) -> Acc segments(Pid) -> [SegLen, ...] stop(Pid) -> ok Per the port's gen_server convention, `gen_server:start_link/2` returns a raw Pid (not `{ok, Pid}`); the API takes the Pid directly so multiple per-actor servers coexist without a registered-name collision. `init/1` dispatches on the Opts arg to call either `log:open_disk/2` (default 1 GiB threshold = effectively no rotation) or `log:open_disk/3` (opt-in `{segment_size, N}`). `handle_call/3` translates each public op to the corresponding pure log call and threads the new state through. New `next/tests/log_server.sh` (15 cases): - API smoke: start_link returns a Pid, single append+tip+entries round-trip, replay/3 chronological, segments visible through the wrapper, rotation through wrapper with opt-in `{segment_size, 16}`, stop returns ok. - Five concurrent-writer tests, each: spawn N=3 writers, each firing M=2 appends of `{I, J}`, parent waits on N `{done,_}` messages via a Y-combinator-shaped receive loop. Assertions cover (a) tip = N*M, (b) length(entries) = N*M, (c) every `{I, J}` pair appears exactly once via `lists:all/2` membership (no losses, no dupes), (d) reopening from disk via `log:open_disk/2` reproduces a byte-equal entries list, (e) every writer's index appears in the entries list (interleaving witnessed). Erlang-port gotchas worked around this iteration: (a) Named recursive fun `fun WaitFn(0) -> ok; WaitFn(K) -> ... end` errors as "fun-ref syntax not yet supported" — rewritten as `fun (_, 0) -> ok; (Self, K) -> ... Self(Self, K - 1) end` then called as `Wait(Wait, N)`. (b) `lists:foreach/2` isn't registered (only `lists:map/2`) — use `lists:map/2` and discard the result list when running side-effecting closures. (c) gen_server message round-trip in this interpreter is ~2s per call, so concurrent N*M was tuned to 6 (`N=3, M=2`) to keep the whole 15-test suite under 60s wall clock; the test's correctness assertions don't depend on N*M magnitude. Erlang conformance **761/761** unchanged (log_server.erl is in next/, not lib/erlang/). Step 3c (both .a and .b) now fully ticked in plans/fed-sx-milestone-1.md.

giles	897449cb35	fed-sx-m1: Step 3c.a segment rotation — log:open_disk/3, <ActorId>-NNNNNN.log filename, threshold-driven rotation; 10/10 log_rotate tests ... `next/kernel/log.erl` rewritten around a `seg_lens :: [N0, N1, ...]` per-segment entry-count list + a `seg_size` byte threshold. Filename scheme moved from `<ActorId>.log` to `<ActorId>-NNNNNN.log` (6-digit zero-padded) so `file:list_dir`'s alphabetical sort coincides with numeric order. `open_disk/3(ActorId, BasePath, [{segment_size, N}])` opts a caller into a smaller rotation threshold; `open_disk/2` keeps a 1 GiB default that effectively never rotates (preserves Step 3b acceptance — log_disk.sh unchanged in behaviour). Rotation rule in `place_append/4`: if the active segment's pre-append encoded size is already >= threshold AND it holds at least one entry, the new activity opens a fresh segment; otherwise it extends the current active segment. A single huge entry that exceeds the threshold stays alone — never rotated recursively. On reopen, `load_all_segments` lists the dir, filters `<ActorId>-NNNNNN.log`, sorts numerically (insertion sort — `lists:sort/1` isn't registered in this port, only `lists:append/2`/`lists:reverse/1`/`lists:filter/2`/etc.), reads each via `try_read_segment`, and concatenates the entries to rebuild flat `entries` + `seg_lens`. Erlang-port gotchas worked around during this iteration: (a) String literals like `"foo"` in this port are NOT charlists — `[H|T] = "foo"` badmatches and `length("foo")` errors as "not a proper list". `parse_segment_name` builds prefix/suffix from `atom_to_list/1` + explicit `[$-]` / `[$., $l, $o, $g]` cons. (b) Cross-arg variable repetition (`strip_prefix([C | Rest], [C | PRest])`) was rewritten to explicit `case C =:= P` for robustness. (c) `Pattern = Binding` syntax in a case clause (`[_|_] = Lst when length(Lst) > 1 -> ...`) errors as "unsupported pattern type 'match'" — replaced with `Lst when is_list(Lst), length(Lst) > 1`. Tests: - new `next/tests/log_rotate.sh` (10 cases): no-opt single-seg-after-3, rotation-fires-on-threshold, rotated-chronological, reopen-rebuilds-history, reopen-rebuilds-same-seg-shape, huge-single-entry-stays-1-seg, append-after-huge-keeps-order, tip-monotonic-across-rotations. - `next/tests/log_disk.sh` updated to the new filename (`corrupted-000000.log`); stays 12/12. - Erlang conformance 761/761 unchanged (log.erl is in next/, not lib/erlang/). 3c.a ticked in plans/fed-sx-milestone-1.md; 3c.b (gen_server-mediated concurrent appends) is the next iteration.
