+# OrbisRPC Production Report
+
+Build under review: `9d9c5b7` (daemon 0.4.0 line, `main`), payload
+`build-sdk/orbisrpc_sdk.elf` (2,071,536 B, daemon-world linkage only,
+zero baked titles). Verified: host unit + ASan/UBSan + e2e ALL PASS;
+linkage gate (libkernel_web / libSceLibcInternal / libSceNet, never
+libkernel.so). Running on-console at 192.168.1.136 via elfldr:9021.
+
+## Architecture
+
+- `daemon.c` — outer connect cycles (jittered backoff, 10-fail 10-min
+  cadence) + inner session loop (12 s poll, 2-hit commit debounce,
+  playback queue of one). Re-reads config every cycle; learned titles
+  persist via atomic save. Token-4004 waits for a config fix, never exits.
+- `detect.c` — sandbox-mount scan (authoritative ID) + save/appdir/atime
+  signals + eboot-count fast-switch. Name chain: config override ->
+  app.db (SQLite readonly) -> appmeta/sfo/appxml -> Sony TMDB live ->
+  raw-ID fallback. Tri-state unknown-hold, 5-min raw retry.
+- `discord.c`/`ws.c`/`tls.c` — gateway v10, TLS 1.2 ceiling,
+  VERIFY_REQUIRED against curated bundle, masked frames, HB ack tracking.
+- `art.c` — mp: proxy via external-assets, pack-pattern fallback,
+  uploaded-key fallback, memory + 7-day disk cache. Home tile: PlayStation
+  logo default; game tile: small system badge.
+- `health.c`/`updater.c`/`manifest.c` — dirty-boot marker, 60 s stable
+  gate, safe mode, signed all-or-nothing staging, boot rollback.
+- `cfg.c`/`lock.c`/`timesync.c` — schema'd fallible config, sysctl-liveness
+  single instance, SNTP wall clock for timer ms.
+- `tools/evict.c` — SIGTERM-then-SIGKILL deploy rotation for the locked daemon.
+
+## State machine
+
+NONE -> HOME ("PlayStation 4" + logo) <-> GAME (name + art + badge +
+ticking timer). Media titles map to Watching/Listening. Resume window:
+same title back within 10 min (or cross-restart via session.json) resumes
+the timer. Sessions append to playtime.log ledger.
+
+## Third-party logic ported (verified against source)
+
+- PS4-Rich-Presence (Python/C#): TMDB `_00` HMAC construction (live-200
+  verified), persistent mapped cache (self-learning map), title-ID hover
+  text, sandbox/NPXS-skip detect, backoff cadence, asset-key fallback.
+- PSN-API tool: small system badge pattern.
+- SonicLoader: read-only app.db tiers (appbrowse/appinfo/param.json).
+- Deliberate skips: PSN credentials, UI editors, PS1/PS2 lists, extra
+  toggles, third-party scrapes (reasons in git history/discussion).
+
+## Fixed this cycle
+
+Sandbox param.sfo source, details-ID duplication, user `titles`
+overrides, `home_art`, shipped logo default, app.db SQLite names,
+self-learning map, presence-builder test seam, small badge, strncpy NUL
+hardening, home_art validation, 4004 survival, cfg_save return,
+evict.elf deploy tool, CI ASan+e2e jobs.
+
+## Not fixed (external / out of scope)
+
+- Sony TMDB unreachable from the console (TCP filtered; correct URL
+  proven from LAN). Mitigated: app.db + learning map.
+- GoldHEN settings-page loader segfaults every ELF (external).
+- IME dialog init errors (external API behavior).
+- Vesktop `?` tile (client quirk; phone renders fine).
+- Dead Discord notify webhook (cosmetic post-push hook).
+
+## Risks
+
+- PS4 app.db schema varies by firmware: tiers fail soft, fallback chain
+  covers. Worst case is today's behavior, never worse.
+- Bare home_art keys are trusted: a typo drops the home tile only.
+- Full titles map (64) stops learning with a log line.
+
+## Hardware matrix (proven)
+
+Gateway ready, TLS-ECDHE suite, game detection + ticking timer post-SNTP,
+mp: art serving (phone), duplicate-ID gone, evict clean-stop rotations,
+reboot recovery. Pending eyes: appdb name flip, badge render, logo tile.
+
+## Readiness
+
+Production for the daemon scope. Installer/PKG remains out of scope per
+directive. Ship it.
