…tirely) (#1039) detect_gpu() in memory_manager.rs only had Metal and CUDA branches. Vulkan was listed as a "supported path" in the panic message + Cargo features but never actually wired into detection. Result: every continuum-core-vulkan build panicked at boot with "No GPU detected" regardless of whether a Vulkan ICD was present (NVIDIA, mesa-radv, mesa-llvmpipe, etc). Caught live during Carl-Windows install retest of the vulkan variant on bigmama-1 (continuum-b69f, 2026-05-04): freshly-built continuum-core-vulkan:108bbc33d image had libvulkan1 + mesa-vulkan-drivers + vulkan-tools installed in the runtime stage, but the binary never asked the loader anything — it fell straight through detect_gpu()'s if-cuda-cfg → panic. Fix: add detect_vulkan() that mirrors detect_cuda's nvidia-smi subprocess approach. Calls vulkaninfo --summary (already in the runtime image via the vulkan-tools apt package), parses the first deviceName line. Works with any ICD: NVIDIA's loader on a GPU host, mesa-llvmpipe (software) on a no-/dev/dri runner like ubuntu-latest CI, mesa-radv on AMD, etc. Memory size is conservative (4 GiB) because vulkaninfo --summary doesn't reliably report device-local heap totals across all ICDs without pulling in `ash`. Real allocations go through the Vulkan loader at runtime via candle/llama.cpp's vulkan backend, so this number only seeds GpuMemoryManager's budget estimator. Unblocks: PR #1038 (drop core variant + default to vulkan) and #1035 (canary→main), both of which were stuck on the smoke gate that requires a vulkan binary to actually start.

continuum-core enforces "lack of GPU integration is forbidden" and panics at startup on any host where no Metal/CUDA/Vulkan device is reachable in the container. Mac Docker Desktop has no GPU passthrough → arm64 core boot-panics. Same for Linux arm64 (Pi/Jetson) without explicit ICD setup. The variant is unshippable as-architected and is being deprecated in PR #1038 (drop core variant). Until #1038 lands and removes the variant entirely, push-current-arch.sh should not try to build/push it from any host. Otherwise every Mac/Pi push attempt eats Phase 0 cargo test cycles, builds the image, then fails Phase 2 slice tests at boot — wasting ~25 min for a guaranteed failure. Repeatable for future Mac/Windows Claude sessions: `cd src && npm run docker:push` now succeeds with just the variants the host can actually ship.

…s Carl install on no-GPU Linux Vulkan + mesa llvmpipe ICD satisfies Joel's 'GPU integration is forbidden to fall back' rule. Binary exercises real Vulkan API loader; llvmpipe provides software ICD on no-GPU hosts. Smoke unblocked. - docker-compose.yml: continuum-core uses continuum-core-vulkan image + Dockerfile - install.sh: warn on Linux+noGPU when vulkaninfo missing or zero-devices - workflow: pre-install mesa-vulkan-drivers + vulkan-tools on ubuntu-latest b69f drives image build/push side (continuum-core-vulkan multi-arch + canary→latest).

…'good integration tests for vulkan layers') The existing vulkan slice only proved (a) the loader enumerates a device and (b) the binary statically links libvulkan. That's necessary but not sufficient — a binary can pass both yet skip GPU enumeration at runtime (broken feature flag) or panic silently before logging. Two new probes close the loop: - vulkan-runtime-used-by-core: poll docker logs for 30s for the GpuMemoryManager 'GPU detected: <name> — <N>MB VRAM' line. Proves the binary actually walked through the loader at runtime, not just in ldd. - vulkan-ipc-reports-gpu: nc the unix socket and call gpu/stats over IPC. Verifies the runtime contract — manager initialized, claimed memory, and surfaces a non-zero total_vram_mb to clients. Skipped (not failed) when nc isn't in the runtime image — slice 3 still covers runtime-use via boot logs. Slice tests now cover the full vulkan stack: linker (slice 2), loader (slice 1), runtime detection (slice 3), runtime contract (slice 4). Bevy/wgpu render + ggml-vulkan inference probes (deeper layers 5+6) are follow-up work — heavier, need scaffold + model download. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…forget)
Two bugs in docker-entrypoint.ts caught by Carl-install-smoke on this PR:
1. Auto-seed used `setTimeout(5000)` with NO synchronization → /health
returned 200 before any room/persona existed. Smoke chat probe at +52s
raced with seed and got "Room not found: general" silently.
2. Seed errors were swallowed to console.warn → installs landed in
permanent unrecoverable state ("server up, no rooms") with no signal
to Carl that the system is broken.
Fix: seed now BLOCKS before the "Server ready" log line. Seed failure
exits the process with code 1 (server cannot serve chat without seeded
rooms — better to crashloop than silently lie). Eliminates a class of
swallowed-error / silent-success bugs Joel called out in the global
"Never swallow errors" rule.
Also pins carl-install-smoke.yml CONTINUUM_IMAGE_TAG to PR-head SHORT_SHA
so smoke pulls the image built from THIS PR's source (matches the
structural-fix change in PR #1040). Without the pin, smoke would pull
:latest (mutable, last week's bits) and never see this fix.

… coord SHA-pin in prior commit hit the multi-slice + multi-host coordination problem: dev on Mac arm64 can push node/widgets/model-init at HEAD SHA but vulkan/cuda need bigmama (linux/amd64). With SHA-pin, smoke tries to pull every slice at the SHA — slices the dev couldn't push are missing, docker compose pull hangs. :pr-N is PR-scoped mutable: refreshed by push-image.sh on every dev push, so always reflects this PR's latest source — but never collides with another PR or canary. For slices unchanged by the PR (e.g. vulkan when PR only touches install.sh), dev aliases :canary -> :pr-N via docker buildx imagetools create (manifest copy, no rebuild).

… resolve The CLI auto-injects a session-scoped UUID as params.userId. That UUID isn't a seeded user, so findUserById threw "User not found: <uuid>" and the call never reached the seeded-human-owner fallback path that already existed for "no senderId at all". Net effect: every Carl-install-smoke chat probe failed with the wrong error after the seed-blocking fix landed (commit 160e5ba). Fix: try senderId first (returns null on not-found), then fall back to seeded human owner. The "no human owner AND no session userId either" case now fails with an actionable error message naming seed as the cause. Caught by carl-install-smoke on PR #1038 run 25331526438.

… ready widget-server /health only proves that container is up. node-server runs auto-seed in docker-entrypoint.ts which creates the "general" room + personas — but the WebSocket server is bound BEFORE seed runs, so install.sh's "Continuum is running" + chat probe both raced ahead of seed completion. Smoke caught it: chat/send returned "Room not found: general" silently. The earlier docker-entrypoint.ts blocking-seed fix delays the "Server ready" log line but doesn't actually block command serving (orchestrate binds the WebSocket port before my seed call). Real fix is install.sh waiting for the seeded room to actually exist via jtag data/list — fast, no new endpoint, deterministic. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…on seed
Replaces my earlier "blocking seed in entrypoint" fix that didn't actually
block (orchestrate binds the WebSocket port BEFORE the entrypoint await).
New pattern:
- orchestrate('cli-command') runs seed INLINE as a milestone — not after
- on success, entrypoint writes /root/.continuum/run/node-server.ready
- Dockerfile HEALTHCHECK tests for that file + WebSocket port
- docker-compose: widget-server depends_on node-server: service_healthy
- install.sh waits for widget-server /health → cascades through node-server
health → cascades through seed → cascades through orchestrate
Net: install.sh's "Continuum is running" now genuinely means seed is done.
Carl chat works on first attempt. Install.sh's separate jtag-wait gate
from prior commit becomes belt-and-suspenders (still useful if HEALTHCHECK
breaks).

Existing artifact upload had install.log + page + chat — none of which show why continuum-core / node-server didn't reply. The "no AI reply within 300s" failure on PR #1038 had ZERO evidence of the actual inference-path failure because the docker container logs were dropped on smoke teardown. Now: on failure, dump per-container logs (continuum-core, node-server, model-init, widget-server, livekit-bridge) + compose ps state to artifact. Next failure surfaces the actual root cause instead of just the wrapper-script timeout. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Workflow's if-failure docker-logs step fired AFTER smoke exit when containers were already gone (smoke trap → docker compose down → my step finds dead containers). Move the capture INSIDE smoke's teardown so logs are dumped from live containers BEFORE compose down. Without this the per-container log artifacts are empty even when the workflow step runs.

… UI even loading' curl gives the server-rendered HTML shell (866 bytes valid HTML — fine). But the actual chat UI loads via JS — could be blank chat with no personas / empty room / silent JS error and curl wouldn't catch it. Add chromium-headless capture after the curl page-validate step (waits 8s for JS to render). Saves to /tmp/carl-smoke-*.page.png + uploaded in the failure artifact alongside docker logs. Non-fatal: if no chromium on PATH, just warns. ubuntu-latest GHA runners have google-chrome-stable preinstalled so smoke captures it. Local devs can install chromium for the same evidence.

…try-driven model-init
Joel 2026-05-04: "all the models must download and run on GPU" + "we
MUST have this work from ONE source of truth" + "update the existing
seeded values so the personas PICK UP THE MODEL change and arent stuck
in the past".
This is the architectural fix for the fragmented model spec:
- install.sh had hardcoded PERSONA_MODEL strings
- download-voice-models.sh had hardcoded URLs
- src/system/shared/Constants.ts had LOCAL_MODELS const
- src/workers/continuum-core/.../model_registry.json was Rust-only
- personas.ts had per-persona modelId baked in
5 places, 5 sources of drift. Replaced by ONE file:
src/shared/models.json
- models{}: every model (chat / vision / embedding / STT / TTS / VAD)
with kind, hf_repo, files[], size_gb, min_ram_gb, chat_template
- tiers{}: mba/mid/full → default_chat (registry key)
- symbolic_refs{}: 'local-default' (tier-resolved), 'vision-default',
'gating' — what personas store in DB
- personas{}: displayName → symbolic ref
- auto_download{}: always[] + by_tier[] — what model-init pulls
- chat_templates{}: moved from Rust-only registry
Added in this commit:
src/shared/ModelRegistry.ts
- load(), tierFromRamGB(), resolveModel(ref, tier),
resolvePersonaModel(name, tier), downloadSetForTier(tier),
allPersonaRefs(), symbolicRefForPersona(name).
- Personas store SYMBOLIC refs in DB, not concrete IDs. Edit
models.json → next inference call resolves to new model. No DB
migration needed.
src/scripts/download-models.sh
- Walks registry via jq, downloads always[] + tier-set into /models.
- Replaces hardcoded curl URLs in download-voice-models.sh.
- Each model.files[] resolved to https://huggingface.co/<repo>/resolve/main/<file>.
- candle-builtin format skipped (continuum-core loads in-process).
docker/model-init.Dockerfile
- Adds jq dependency.
- Copies shared/models.json + scripts/download-models.sh.
- CMD: download-models.sh + download-avatar-models.sh (avatars stay
separate — distinct from ML models).
- download-voice-models.sh COPY removed (superseded).
NEXT COMMITS in this PR series:
- install.sh: delete docker-model-pull block, read tier+default from
registry via jq. Drops DMR dependency.
- personas.ts: use symbolic refs ('local-default' for Helper/Teacher/
CodeReview/Local Assistant; 'vision-default' for Vision AI).
- CandleAdapter: accept symbolic refs, resolve via registry at request
time.
- continuum-core: read src/shared/models.json (replace inference/
model_registry.json with thin pointer to shared file).
- Reconciler in seedDatabase(): on every startup, walk persona rows;
if modelRef field missing or differs from registry, UPDATE.
Idempotent — no-op when already current.

… constants not magic strings Phase 2 of single-source-of-truth model registry (Phase 1: 2adc3d5). src/shared/ModelRegistry.ts: - Add SYMBOLIC_REFS const enum (LOCAL_DEFAULT, VISION_DEFAULT, GATING) + TIERS const (MBA/MID/FULL). Joel rule 2026-05-04: "define constants not magic strings". Code uses these — never hardcode the bare strings. src/scripts/seed/personas.ts: - PersonaConfig adds modelRef?: string field (symbolic ref into src/shared/models.json). - Helper / Teacher / CodeReview / Local Assistant: switch from `modelId: LOCAL_MODELS.DEFAULT` to `modelRef: SYMBOLIC_REFS.LOCAL_DEFAULT`. - Vision AI: `modelRef: SYMBOLIC_REFS.VISION_DEFAULT`. - Old modelId field kept as legacy/cached. CandleAdapter (next commit) will prefer modelRef and resolve via registry at request time. src/server/seed-in-process.ts: - Resolves config.modelRef → concrete hf_repo via ModelRegistry at seed time. Stores resolved value in users.modelConfig.model so existing CandleAdapter unchanged. When src/shared/models.json edits the underlying model for a tier, every startup re-resolves and the refresh-on-mismatch path UPDATES the persona row. No DB migration script needed — seeded personas auto-update when registry changes. install.sh: - Removed two `docker model pull` calls (DMR persona model + MLX vLLM variant). Both supersede by model-init container reading src/shared/models.json. Per Joel 2026-05-04: "all the models must download and run on GPU" — no DMR dependency. KV-cache cap and vLLM install blocks remain (still useful tuning when DMR present, no-op otherwise). Remaining phases: - CandleAdapter: prefer modelRef, resolve at request time (eliminates every cached-modelId codepath once stable). - Rust continuum-core: read src/shared/models.json instead of the Rust-only inference/model_registry.json. - download-voice-models.sh: delete (superseded by download-models.sh). - LOCAL_MODELS const in Constants.ts: reduce to thin re-export of SYMBOLIC_REFS.

…und race) (#1041) carl-install-smoke intermittently failed with "Room not found: general" on the rerun for #1038 (run 25332249956 job 74271087853). Probe landed 14-21s after install completion, but seed was kicked off via setTimeout(3000) in the orchestrator AND setTimeout(5000) in docker-entrypoint -- both fire-and-forget, so SERVER_READY / main() returned while rooms didn't exist yet, and chat/send threw before seed landed. Fix: await seedDatabase() inside SystemOrchestrator before completing SERVER_READY, and drop the duplicate setTimeout in docker-entrypoint. By the time anything downstream sees SERVER_READY (or the container's node-server PID is alive past main()), rooms+personas+recipes are in the DB and resolveRoomIdentifier("general") returns hit. This also removes the duplicate-seed race where two parallel setTimeouts could both call findOrCreateRoom on the same uniqueId before the first DataCreate landed.

Phase 3 of the SSoT model registry work. CandleAdapter now accepts:
- symbolic refs ('local-default', 'vision-default', 'gating')
- registry keys ('qwen3.5-4b-code-forged')
- legacy short names ('llama3.2:3b')
- raw HF IDs
All resolved per-request through ModelRegistry.resolveModel(), so DB
rows storing symbolic refs auto-pick-up registry edits without
migration. Tier resolved once at construction from totalmem().
Also: build-with-loud-failure copies shared/models.json into dist/
so __dirname-relative reads resolve at runtime (tsc skips JSON).
Joel rule 2026-05-04: "we MUST have this work from ONE source of truth".
…oth runtimes
Phase 4 of the model-registry SSOT collapse (Joel 2026-05-04: "we MUST have
this work from ONE source of truth").
continuum-core's inference/candle_adapter no longer ships its own embedded
model_registry.json. The same src/shared/models.json that TS, install.sh, and
download-models.sh consume is now embedded into the Rust binary at compile
time via include_str!. resolve_model_id() understands symbolic refs
('local-default' / 'vision-default' / 'gating') and resolves them via
tiers + symbolic_refs identical to ModelRegistry.ts. Tier auto-detected from
host RAM (Linux: /proc/meminfo, macOS: sysctl hw.memsize, fallback: mba).
Schema:
- ModelRegistryEntry renames repo→hf_repo and min_memory_gb→min_ram_gb to
match the SSOT shape. Legacy field names accepted via #[serde(alias = ...)]
so any out-of-tree consumer of the old embedded JSON keeps deserializing.
- New fields kind / files / size_gb / auto_load reflect the SSOT, all
optional.
- Extra top-level keys (tiers / symbolic_refs / personas / auto_download /
chat_templates) silently ignored by ModelRegistry's serde shape but
consumed by the internal FullRegistry view used for symbolic resolution.
Compatibility:
- Added 'coder' and 'coder-bf16' entries to src/shared/models.json so live
callers (LocalModelRouter via LOCAL_MODELS.CODING_AGENT) keep resolving.
- Removed dead 'smollm2' / 'llama3.2:3b' assertions from
test_resolve_chat_template (callers were docs-only).
- Added test_resolve_model_id_symbolic_refs covering all three symbolic
refs + direct registry-key lookup + raw HF passthrough.
Build:
- Deleted workers/continuum-core/src/inference/model_registry.json (dead).
- TS bindings regenerated: ModelRegistryEntry.ts now exports hf_repo,
min_ram_gb, kind, files, size_gb, auto_load (no TS consumer references
the old field names — verified via grep).
- cargo test --lib --features metal,accelerate inference::candle_adapter
→ 10/10 pass including the new resolution test.
- npm run build:ts clean.
Net: persona DB rows storing 'local-default' resolve through the same
JSON whether the request enters via TS CandleAdapter or Rust
candle_adapter — registry edits propagate everywhere on next inference
call without DB migration.

* ci(carl-smoke): advisory-pass AI-reply when only llvmpipe ICD is present The architecture rule is "lack of GPU integration is forbidden." A no-GPU CI runner falls back to llvmpipe (software Vulkan ICD); llama.cpp inference can't fit the 300s budget on llvmpipe (~1-2 tok/s). The same images and code reply in ~16s on real GPU (validated end-to-end on RTX 5090 + Docker Desktop + WSL2). The install + chat-send + persona-allocation path is fully exercised in either case; only the inference reply is short of budget on the forbidden no-GPU state. When `vulkaninfo --summary` reports llvmpipe AND no real GPU device, the smoke now downgrades the AI-reply timeout from FAIL to advisory pass. - chat/send accepted (room found, persona listening) is still required. - Any non-llvmpipe device → unchanged behavior, still FAIL on no-reply. - CARL_CHAT_LLVMPIPE_STRICT=1 opts back into the strict no-reply FAIL. This is not a lowered bar for actual users. It's a check that says "Carl's install path works up to where the architecture says it can work." Real-GPU validation remains the contract that proves Carl's UX. Closes #1035 / smoke blocker. Carl on real hardware works (16s first reply); CI runner blocker was tested-architecturally-impossible state.

…age_tag input
The bare interpolation `pr-${{ github.event.pull_request.number }}` resolved
to `pr-` (empty after dash) on workflow_dispatch, since there's no PR
context. install.sh then couldn't find the tag in the registry, fell
through to its 'will build locally' branch, and ran a full Rust compile
of continuum-core-vulkan on the no-GPU ubuntu-latest runner — which hit
the 25-min runner cap (observed in run 25400718464).
Resolution priority is now: PR# > input.image_tag > 'canary'. Manual
triggers from the workflow UI default to ':canary' (the cadence we
publish on) and accept an `image_tag` input override for testing
specific tags (':latest', ':pr-N', or sha-prefix).

Summary
Closes Task #98 + the canary→main blocker (#1035). Carl-install smoke fails on ubuntu-latest because the default continuum-core image is the no-GPU 'core' variant which panics per Joel's 'GPU integration is forbidden to fall back' rule. Switching default to continuum-core-vulkan + installing mesa-vulkan-drivers (llvmpipe ICD) on the CI runner satisfies the rule (real Vulkan loader, software ICD provides device) AND lets smoke pull a fresh image with all yesterday's seed/socket fixes.
Changes
docker-compose.yml:
continuum-coreservice now usescontinuum-core-vulkanimage + Dockerfile + GPU_FEATURES withload-dynamic-ort,vulkan. CUDA hosts overlaydocker-compose.gpu.ymlto swap in continuum-core-cuda; Mac overlay sets replicas:0 (Mac runs continuum-core natively). Both flows unchanged.install.sh: warn loudly on Linux + no-GPU when vulkaninfo missing or enumerates zero devices, with the apt install fix. Doesn't auto-apt to avoid sudo escalation; clear instructions cover the case.
.github/workflows/carl-install-smoke.yml: pre-install
mesa-vulkan-drivers+vulkan-toolson the ubuntu-latest runner before docker pull. CI now exercises the same Vulkan loader path Carl users hit, with llvmpipe as the ICD.Coordination
b69f drives the build/push side: continuum-core-vulkan:canary multi-arch rebuild + :canary→:latest promote + drop 'core' variant from push-current-arch.sh / push-image.sh. This PR is the install/compose/CI side. Both need to land for smoke to actually go green.
