resolved 56e0b520-86a6-41bd-94ef-aa1769b71b49
`observability`, `llm`, `persistence`, `attempts`, `ui`, `genetic_algorithms`, `forensics`I inspected the uploaded repo and the current gap is very concrete:
src/llm.rs:84-103 and src/llm.rs:122-183 send non-streaming requests and return only extracted assistant text / parsed JSON.src/llm.rs:214-235 discards response headers, raw response bytes, router target headers, and usage metadata.src/llm.rs:250-256 caps error bodies at 2 KB for display, but there is no uncapped artifact storage elsewhere.src/minds.rs:106-123 and src/minds.rs:126-142 immediately normalize successful perceive/intend text.src/minds.rs:385-387 uses split_whitespace().join(" "), which destroys raw whitespace, line breaks, and chunk/token shape.src/minds.rs:176-215 preserves adjudication raw text only for rejected retry attempts. Successful adjudication raw JSON is not preserved as a first-class artifact.src/kernel.rs:594-701 stages semantic audit events in memory; the LLM artifacts are not independently durable while the call is running.src/world_store/mod.rs:410-426 and migrations/0002_world_store.sql:36-54 show the attempt record is only status/timing/progress/failure/delta.src/read_models.rs:1425-1457 builds attempt detail from the attempt record plus audit events. There is no LLM-call surface.src/resource_catalog.rs:430-442 has the attempt list columns wired to completed_at, but the actual record field is ended_at, so even the existing attempts UI is under-serving the operator.The current incident proves why this matters: the latest first-meeting attempt generated/evaluated 56596 completion tokens, hit 57344 total tokens, truncated, returned HTTP 200, and Chukwa retained only “empty assistant message” as the meaningful attempt-level result.
Below is the ticket I’d submit. It is intentionally declarative and maximal.
Priority: P1
Type: feature
Labels: observability, llm, persistence, attempts, ui, genetic_algorithms, forensics
Code context: src/llm.rs, src/minds.rs, src/kernel.rs, src/world_store/*, src/read_models.rs, src/server.rs, src/resource_catalog.rs, migrations/
Chukwa must persist complete LLM cognition traces for every turn attempt, successful or failed. The attempts table should become an operator cockpit, and full LLM request/response/token artifacts should become first-class durable resources linked to attempts, audit events, worlds, agents, profiles, and turns.
Do not merely add capped diagnostics. Do not only improve failure strings. Do not only store excerpts. Store the raw data.
This includes:
get_turn_status, /attempts, and /attempts/:id immediately explain what happened.This is not a resurrection mechanism. Historical failed attempts remain failed. The goal is to preserve raw cognition artifacts for analysis, debugging, model evaluation, future genetic algorithms, and operator visibility.
Current Chukwa throws away the most valuable data.
src/llm.rs asks the router for "stream": false, parses the fully buffered response, extracts choices[0].message.content, trims it, and returns a string. If the text trims empty, Chukwa records only router returned an empty assistant message.
src/minds.rs further normalizes successful perceive/intend output with split_whitespace().join(" "), so even successful turns lose raw formatting and raw generation shape.
src/kernel.rs stores semantic audit events, but not the LLM call that produced them. Perception and intent success events contain normalized text, not the raw assistant output. Adjudication success stores narration/transitions, not the full raw JSON response. Rejected adjudication attempts store raw_response, but that richer path is uneven and only covers one failure class.
attempts currently stores progress, failure_reason, and delta; it does not store failure class, failed phase, failed entity, model/backend, finish reason, usage, response shape, raw body, chunks, tokens, or correlation IDs.
The router is OpenAI-compatible, and the Chat Completions shape already carries fields Chukwa should preserve, including choices, message.content, finish_reason, and usage; streaming returns chunks when stream is enabled. ([OpenAI Platform][1]) Postgres is an appropriate place to store these artifacts: TOAST automatically compresses and/or moves large TEXT, BYTEA, and JSONB-style varlena values out of line when they are too large for normal table rows. ([PostgreSQL][2])
Implement LLM cognition traces as a new durable subsystem.
The canonical world/audit chain remains semantic. The raw LLM trace layer sits beside it and links into it. Attempts become the top-level diagnostic entry point; LLM calls become browseable resources.
Do not cap raw storage. Cap only list-view previews.
Do not wait until attempt commit/fail to persist traces. Insert a call row before each LLM request, append stream chunks as they arrive, and finish/fail the call row when the request ends. If the pod dies mid-call, the attempt may be interrupted, but the partial trace must survive.
Do not add generation caps in this ticket. The purpose here is capture. Policy/tuning can happen after we have complete evidence.

Implement these in both src/world_store/postgres.rs and src/world_store/memory.rs.
Replace the current throwaway LLM path in src/llm.rs.
Replace ureq with an async streaming client. Use reqwest with json, stream, and rustls-tls features, plus futures-util for stream handling.
Remove run_blocking_llm_io once no blocking HTTP remains.
Every Chukwa LLM request must set:
{
"stream": true,
"stream_options": {
"include_usage": true
}
}
Keep response_format for adjudication JSON calls. If the router/backend rejects stream_options, record that HTTP failure as its own llm_calls row, then retry the same logical call once with stream_options removed. Both rows must remain linked via fallback_of_call_id.
Do not lose data from fallbacks. Existing chat_json_raw has a response-format fallback path; preserve both the failed schema-format call and the fallback call as separate LLM call rows.
Create a trace context that kernel/minds pass into every cognition call:
pub struct AttemptTraceContext {
pub store: Arc<dyn WorldStore>,
pub attempt_id: AttemptId,
pub world_slug: Slug,
pub attempted_turn: u64,
pub worker_id: String,
pub next_llm_call_seq: Arc<AtomicU32>,
}
pub struct LlmCognitionContext {
pub attempt: AttemptTraceContext,
pub phase: LlmPhase,
pub entity_id: Option<String>,
pub profile_label: Option<Label>,
pub profile_hashes: Option<AgentProfileHashes>,
pub logical_attempt_number: Option<u32>,
}
The LLM client must generate a llm_call_id before sending HTTP, insert llm_calls, insert llm_call_messages, and store the full request_json artifact.
Every request to the router must include:
X-Chukwa-Attempt-Id: <attempt uuid>
X-Chukwa-Llm-Call-Id: <llm_call uuid>
X-Chukwa-World-Slug: <world slug>
X-Chukwa-Attempted-Turn: <turn number>
X-Chukwa-Phase: perceive|intend|adjudicate
X-Chukwa-Entity-Id: <entity id, if any>
X-Client-Request-Id: chukwa:<attempt_id>:<call_seq>:<llm_call_id>
OpenAI’s own debugging guidance supports client-supplied request IDs via X-Client-Request-Id, and says this value should be unique and can be used to look up whether a request was received when normal response headers are unavailable. Use the same pattern for router/backend correlation. ([OpenAI Platform][3])
Persist all non-sensitive response headers in llm_calls.response_headers.
Specifically extract and store:
x-request-id
x-router-source
x-router-model
x-router-upstream-model
x-router-target
x-router-slot
x-router-deployment
The existing docs/llm-router.md says these x-router-* headers are the most reliable truth for the actual backend selected by a request. Chukwa currently ignores them. That must stop.
For every SSE data: frame:
raw_json.choices[*].delta.content and append it to in-memory reconstruction.llm_call_chunks row before reading the next chunk.finish_reason, store it.usage, store it and update the call summary.llm_call_tokens.The reconstructed assistant text must be stored as assistant_text_raw before any trimming, normalization, or JSON parsing.
If the router returns a non-2xx response, store the full body as router_error_body. The human-facing failure_reason may remain short, but the DB artifact must be uncapped.
If a backend returns a buffered JSON response despite stream: true, store the full response body as response_body, parse what can be parsed, and record metadata.unexpected_non_stream_response = true.
Change LlmError from string-only variants to structured variants:
pub enum LlmError {
Config {
message: String,
},
Transport {
message: String,
llm_call_id: Option<LlmCallId>,
failure_class: &'static str,
},
HttpStatus {
status: u16,
body_preview: String,
llm_call_id: Option<LlmCallId>,
failure_class: &'static str,
},
InvalidResponse {
message: String,
llm_call_id: Option<LlmCallId>,
failure_class: &'static str,
details: serde_json::Value,
},
Serialization {
message: String,
llm_call_id: Option<LlmCallId>,
failure_class: &'static str,
details: serde_json::Value,
},
}
Keep Display concise for failure_reason, but never rely on Display as the only evidence.
Required failure_class values:
llm_config_error
llm_transport_error
llm_http_status
llm_stream_parse_error
llm_missing_choices
llm_missing_message
llm_missing_content
llm_unexpected_content_shape
llm_empty_assistant_message
llm_json_parse_error
llm_adjudication_validation_error
llm_response_format_unsupported
llm_usage_missing
llm_finish_length
Change:
pub fn perceive(world: &World, agent: &Entity) -> Result<String, CognitionError>
pub fn intend(world: &World, agent: &Entity, perception: &str) -> Result<String, CognitionError>
pub fn adjudicate(...) -> Result<AdjudicationOutcome, AdjudicationError>
to:
pub async fn perceive(
world: &World,

pub async fn intend(

pub async fn adjudicate(
world: &World,
agent: &Entity,
intent: &str,
trace: &AttemptTraceContext,
profile_hashes: Option<&AgentProfileHashes>,
) -> Result<AdjudicationOutcome, AdjudicationError>
ObservedText must carry:
pub struct ObservedText {
pub llm_call_id: LlmCallId,
pub raw_text: String,
pub normalized_text: String,
}
JsonCompletion<T> must carry:
pub struct JsonCompletion<T> {
pub llm_call_id: LlmCallId,
pub raw_text: String,
pub parsed: Result<T, String>,
}
For perceive/intend:
assistant_text_raw.normalized_text.assistant_text_normalized.llm_call_id.The simulation can continue using normalized text. The trace must preserve raw text.
For adjudication success, store:
llm_call_idUpdate PendingAuditEvent::Adjudication to include llm_call_id.
Update PendingAuditEvent::AdjudicationRejected to include llm_call_id.
The audit event payload may include a link:
{
"entity_id": "mira",
"llm_call_id": "...",
"narration": "...",
"entities_touched": [...]
}
Do not copy the giant raw response into every audit event. The raw response lives in llm_call_artifacts.
Before each call:
perceive[mira]: starting LLM call 1
During long streaming calls, update progress periodically:
perceive[mira]: LLM call 1 streaming; 482 chunks; 12043 chars; 97s elapsed
On finish:
perceive[mira]: LLM call 1 finished; finish_reason=length; completion_tokens=56596
Do not update progress on every token; update every 5 seconds or every 256 chunks, whichever comes first. The chunks themselves are persisted every chunk.
When a turn fails, populate:
attempts.failure_class
attempts.failed_phase
attempts.failed_entity_id
attempts.last_llm_call_id
attempts.llm_trace_summary
For the current observed failure, the attempt row should end up shaped like:
{
"failure_class": "llm_empty_assistant_message",
"failed_phase": "perceive",
"failed_entity_id": "mira",
"last_llm_call_id": "...",
"llm_call_count": 1,
"llm_prompt_tokens": 748,
"llm_completion_tokens": 56596,
"llm_total_tokens": 57344,
"llm_trace_summary": {
"last_call": {
"phase": "perceive",
"entity_id": "mira",
"model_requested": "@chat",
"router_target": "local:gemma-4-26b@centroid-5060ti",
"finish_reason": "length",
"truncated": true,
"assistant_text_chars": 0,
"content_trimmed_chars": 0
}
}
}

start_llm_call: insert call row, messages, request artifact, timeline event.append_llm_call_chunk: insert chunk row, update chunk counters and cumulative text counters.finish_llm_call: update status/end fields, write artifacts, update attempt aggregate counters.fail_llm_call: update status/end fields, write failure artifacts, update attempt aggregate counters.Chunk inserts must be durable before reading the next upstream chunk.
Implement parallel in-memory structures in src/world_store/memory.rs.
This is required because most MCP/read-model/UI tests use MemoryWorldStore.
Add:
llm_calls: HashMap<Uuid, LlmCallRow>
llm_messages: HashMap<Uuid, Vec<LlmMessageRow>>
llm_chunks: HashMap<Uuid, Vec<LlmChunkRow>>
llm_tokens: HashMap<Uuid, Vec<LlmTokenRow>>
llm_artifacts: HashMap<(Uuid, LlmArtifactKind), LlmArtifactRow>
attempt_timeline: HashMap<Uuid, Vec<AttemptTimelineRow>>
Extend existing tools and add new tools.
get_turn_statusAdd optional arguments:
{
"include_diagnostics": { "type": "boolean", "default": false },
"include_llm_calls": { "type": "boolean", "default": false }
}
Default response remains backward-compatible, but now includes the summary columns if present:
{
"failure_class": "...",
"failed_phase": "...",
"failed_entity_id": "...",
"last_llm_call_id": "...",
"llm_call_count": 3,
"llm_prompt_tokens": 1234,
"llm_completion_tokens": 5678,
"llm_total_tokens": 6912
}
When include_llm_calls=true, include call summaries only, not giant artifacts.
list_attemptsAdd the same summary fields to every row. Fix the underlying UI/list mismatch so the field is ended_at, not completed_at.
list_llm_callsInput:
{
"attempt_id": "uuid",
"world_slug": "optional",
"phase": "optional perceive|intend|adjudicate",
"entity_id": "optional",
"status": "optional running|succeeded|failed|interrupted",
"limit": 100,
"cursor": "optional"
}
Output: call summaries.
get_llm_callInput:
{
"llm_call_id": "uuid",
"include_messages": true,
"include_artifacts": false,
"include_chunks_preview": true,
"include_tokens_preview": true
}
Output: full metadata, messages, artifact metadata, and previews.
get_llm_call_artifactInput:
{
"llm_call_id": "uuid",
"artifact_kind": "assistant_text_raw"
}
Output the full artifact. This is intentionally uncapped.
list_llm_call_chunksInput:
{
"llm_call_id": "uuid",
"limit": 500,
"cursor": "optional"
}
Output paginated chunks.
list_llm_call_tokensInput:
{
"llm_call_id": "uuid",
"source": "optional stream_logprobs|final_logprobs|posthoc_tokenizer|stream_delta",
"limit": 1000,
"cursor": "optional"
}
Output paginated token observations.
Add browseable LLM call routes. Keep all raw views behind the existing graph UI auth gate.
In src/server.rs, add:
.route("/llm-calls", get(llm_calls_list))
.route("/llm-calls/:llm_call_id", get(llm_call_detail))
.route("/llm-calls/:llm_call_id/chunks", get(llm_call_chunks_list))
.route("/llm-calls/:llm_call_id/tokens", get(llm_call_tokens_list))
.route("/llm-calls/:llm_call_id/artifacts/:artifact_kind", get(llm_call_artifact_raw))
.route("/attempts/:attempt_id/llm-calls", get(attempt_llm_calls_list))
.route("/w/:slug/attempt/:attempt_id/llm-calls", get(attempt_llm_calls_list_world))
Add ResourceKind::LlmCall.
Register:
const LLM_CALL_SPEC: ResourceSpec = ResourceSpec {
kind: ResourceKind::LlmCall,
display_name: "LLM call",
plural_path: "/llm-calls",
detail_path_template: "/llm-calls/:llm_call_id",
id_scope: IdScope::GlobalUuid,
default_list_columns: &[
"llm_call_id",
"attempt_id",
"world_slug",
"phase",
"entity_id",
"status",
"model_requested",
"router_target",
"finish_reason",
"total_tokens",
"duration_ms",
],
reference_rules: GLOBAL_RULES,
classification: ResourceClassification::Browseable,
};
Add reference rules for:
llm_call_id
last_llm_call_id
llm_calls.[*].llm_call_id
events.[*].llm_call_id
Change attempt default columns from:
["attempt_id", "world_slug", "status", "enqueued_at", "completed_at"]
to:
[
"attempt_id",
"world_slug",
"status",
"ended_at",
"failure_class",
"failed_phase",
"failed_entity_id",
"llm_completion_tokens",
"last_llm_call_id"
]
/attempts/:attempt_id must show:
For a failed attempt, the top of the page should answer:
Failed in perceive[mira].
Failure class: llm_empty_assistant_message.
Last LLM call: <link>.
Model/backend: @chat → local:gemma-4-26b@centroid-5060ti.
Finish reason: length.
Prompt/completion/total tokens: 748 / 56596 / 57344.
Raw output artifact: <link>.
Stream chunks: <link>.
/llm-calls/:llm_call_id must show:
The raw artifact route should stream text/plain or application/json directly so huge outputs can be opened without rendering the entire blob inside the generic HTML page.
Chukwa must capture whatever the router already sends today. In addition, update the router to preserve Chukwa correlation headers in logs and to return backend metrics when available.
Required router additions:
X-Chukwa-Attempt-Id, X-Chukwa-Llm-Call-Id, X-Chukwa-Phase, and X-Client-Request-Id.x-router-backend-task-id
x-router-prompt-tokens
x-router-completion-tokens
x-router-total-tokens
x-router-truncated
x-router-finish-reason
Chukwa must store these fields if present, but Chukwa must not depend on them to preserve stream chunks and raw output.
Add tests at every layer.
Update tests/migrations.rs:
llm_calls, llm_call_messages, llm_call_chunks, llm_call_tokens, llm_call_artifacts, and attempt_timeline_events exist.world_audit_events.llm_call_id exists.llm_calls is browseable.In both Postgres and memory stores:
start_llm_call inserts call, messages, and request artifact.append_llm_call_chunk persists every chunk in order.finish_llm_call stores raw assistant text, response headers, usage, finish reason, and updates attempt aggregate counters.fail_llm_call stores uncapped error body and failure class.list_llm_calls_for_attempt returns calls in call_seq order.get_llm_call_artifact returns full raw content, not a preview.world_audit_events.llm_call_id links semantic audit events to trace rows.Use a local mock HTTP server.
Test cases:
Streaming text response:
"one", " two", " three".llm_call_chunks."one two three".Empty assistant response:
llm_empty_assistant_message.last_llm_call_id points to the failed call.Usage chunk:
HTTP 500:
llm_call_artifacts.router_error_body stores the full body.JSON parse failure:
llm_json_parse_error.Adjudication validation rejection:
adjudication_rejected audit event links to llm_call_id.Response format fallback:
response_format.llm_call_id.llm_call_id.fail_attempt.get_turn_status default remains backward-compatible.get_turn_status(include_diagnostics=true, include_llm_calls=true) includes summary and LLM call list.list_llm_calls paginates.get_llm_call_artifact returns full raw text.list_llm_call_chunks returns chunks in sequence order.list_llm_call_tokens returns token observations./attempts?format=json includes new summary fields./attempts/:id?format=json includes timeline and LLM call summaries./llm-calls?format=json lists calls./llm-calls/:id?format=json returns metadata and artifact links./llm-calls/:id/artifacts/assistant_text_raw returns uncapped raw output.Run a fresh single-moth turn.
Acceptance:
attempts.llm_call_count > 0.llm_calls row.request_json.assistant_text_raw.assistant_text_normalized or parsed_json, as appropriate.llm_call_id./attempts/:id shows LLM calls./llm-calls/:id/artifacts/assistant_text_raw returns full raw text.Run first-meeting.
Acceptance, regardless of whether the turn commits or fails:
failure_class, failed_phase, failed_entity_id, and last_llm_call_id are populated.llm_call_chunks and llm_call_artifacts.assistant_text_raw preserve the generated output.get_turn_status(include_diagnostics=true, include_llm_calls=true) explains the failure without reading pod logs./attempts and list_attempts include:
failure_class
failed_phase
failed_entity_id
last_llm_call_id
llm_call_count
llm_prompt_tokens
llm_completion_tokens
llm_total_tokens
The attempt list no longer uses the nonexistent completed_at field.
For a generated output larger than 2 KB:
failure_reason may remain concise.The world state, committed turn format, and audit-event semantics remain stable. Chukwa may still use normalized perception/intent text for simulation behavior, but the raw layer must preserve the unnormalized output.
Old attempts remain as they are. UI should display:
LLM trace unavailable: attempt predates llm trace capture.
Do not try to reconstruct missing raw data from pod logs.
Add migration 0004_llm_cognition_traces.sql.
Add DTOs and trait methods in world_store/mod.rs.
Implement Postgres store methods.
Implement Memory store methods.
Add LLM trace structs and async streaming client in llm.rs.
Convert minds.rs cognition functions to async traced calls.
Thread trace context through kernel.rs.
Link audit events to llm_call_id.
Add attempt summary updates.
Add MCP tools and response fields.
Add resource catalog entry and HTTP/UI routes.
Add tests.
Deploy.
Verify on single-moth.
Verify on first-meeting.

The core shift is this: attempts should summarize; LLM calls should preserve; chunks/tokens should prove.
The development team should not keep trying to infer model behavior from failure_reason. Build the trace layer, make it browseable, and preserve every weird, failed, successful, ugly, raw token-bearing artifact as durable data.
Chukwa now persists complete LLM cognition traces — every request, every response chunk, every artifact — as first-class durable resources linked to attempts, audit events, worlds, agents, and component hashes. Attempts surface failure class, failed phase, failed entity, last LLM call, and token totals. Operators can browse the full trace via MCP tools and HTML routes.

The 2dc48e22 runaway-generation phenomenon was not triggered by
either smoke turn today — both committed cleanly with finish_reason=stop.
The trace layer is now armed and ready: when the runaway next
reproduces, every chunk, every cumulative_chars datapoint, and every
finish_reason will be on disk in llm_call_chunks for the next agent
to read directly. That is exactly what this ticket made possible.

2dc48e22 runaway-generation remediation can now proceed
principled. With the trace layer live, the next agent reads actual
prompts + responses + finish_reasons + cumulative_chars + token-usage
rows and targets the fix precisely. Today's smoke didn't reproduce
the runaway, but the moment it next happens the evidence will be on
disk.4601f21a pod-restart investigation now has the trace evidence
backing the LLM-side cause (no longer "the pod restarted, so the
evidence is gone").38d0ba4e (validator + Slug / Label /
entity_id grammar + SQL domain + scenario_names removal + route
validation + ticket-label enforcement + docs sweep + substrate-wipe
migration) stay scoped to that ticket's own dedicated cycle. Items 5
(strict adjudication entity_id) and 6 (rejected drafts not in
canonical audit) were absorbed into Phase G of this ticket since they
were blocking trace correctness./root/.config/chukwa-mcp/mcp.sh
was updated mid-Phase-I to route the 5 new operator tools
(list_llm_calls / get_llm_call / get_llm_call_artifact /
list_llm_call_chunks / list_llm_call_tokens) to /operator-mcp.
Mirror-update of mcp.sh.pre-split was not done; the wrapper has
drifted from the rollback file. Trivial to keep in sync if needed.Awaiting caller acceptance.
Phase A landed at commit 6d2b82f on feat/llm-traces. Pre-authorized in conversation channel by the human; the ticket's HOLD protocol is honored by the in-channel directive — proceeding to in_progress with this comment as the Phase A status.

AttemptDiagnosticsUpdate carries attempt_id so it can't derive(Default) (since AttemptId doesn't). Replaced the auto-derive with an explicit for_attempt(attempt_id) constructor; struct-update syntax still works for partial patches. Phase B's impl reads this field as the WHERE clause target.LlmCallStart carries the full request body (the spec says the store also persists it as the LlmArtifactKind::RequestJson artifact in the same transaction). The TODO comment on start_llm_call in postgres.rs names that intent; Phase B should NOT split this into a follow-up insert.update_attempt_llm_summary's token deltas are increments, not absolutes. This lets per-call updates stack without first reading the row. Spec was ambiguous on this; chose increment semantics because Phase F will land per-call updates from inside finish_llm_call's caller, and absolute semantics would force a SELECT-then-UPDATE on every call.LlmTokenSource is a Rust enum mapped to the llm_call_tokens.source CHECK constraint values via .as_str(). Spec gave source TEXT NOT NULL CHECK (source IN (...)) rather than a PG ENUM, so the Rust side enforces the constraint at the type level even though Postgres uses a CHECK string.LlmCallId does NOT derive Default (Uuid::nil() would be misleading); same convention as AttemptId.tests/migrations.rs — added llm_calls → llm_call entry to TABLE_TO_RESOURCE_KIND so the existing catalog_contract_every_fk_target_is_browseable_or_allowlisted test catches future FK regressions on the new table. Verified the contract test passes against the new migration.Phase A IS deployable on its own. The migration is purely additive — every ALTER TABLE ... ADD COLUMN lands a NOT NULL DEFAULT so existing rows are unaffected, and every new table is empty until Phase B/E wires writes. The deferred FK from attempts.last_llm_call_id → llm_calls(llm_call_id) is DEFERRABLE INITIALLY DEFERRED and only enforces on transaction commit; production never sets last_llm_call_id until Phase F so the FK never trips. All new Rust code is unused at runtime — the trait methods exist on the surface but no caller invokes them.
Proceeding to Phase B (PostgresWorldStore impl of all new trait methods + postgres-tests).
Phase B landed at commit 4f58317 on feat/llm-traces.

3145202 fix(llm): avoid stalling Tokio workers
The 14 LLM-trace WorldStore placeholder bodies in src/world_store/postgres.rs are now real impls against migration 0004. Memory store stays Phase A skeleton (Phase C).
start_llm_call: one txn — INSERT llm_calls (status='running' default), INSERT every llm_call_messages row (sha256/chars/bytes computed Rust-side from the message content), INSERT llm_call_artifacts(RequestJson) carrying the canonicalized request body + sha256 + byte count, INSERT attempt_timeline_events("llm_call_started"). FK violation on attempts(attempt_id) is mapped to AttemptNotFound; (attempt_id, call_seq) unique-violation surfaces as Database.append_llm_call_chunk: one txn — INSERT llm_call_chunks, then UPDATE parent llm_calls cumulative counters (stream_chunk_count++, content_chunk_count += is_content, assistant_text_chars/bytes += chunk_delta, first_chunk_at = COALESCE(first_chunk_at, now())). Per-chunk durability — txn commits before next upstream read.append_llm_call_tokens: one txn, sequential INSERTs (PRIMARY KEY (llm_call_id, token_seq) rejects duplicates).put_llm_call_artifact: single autocommit INSERT … ON CONFLICT (llm_call_id, artifact_kind) DO UPDATE — idempotent upsert. Rejects bodies with neither content_text nor content_json Rust-side as WorldStoreError::Invalid.finish_llm_call: one txn — SELECT … FOR UPDATE on llm_calls (rejects non-'running' as WorldStoreError::Invalid), UPDATE llm_calls setting status='succeeded', ended_at, duration_ms, response_, finish_reason, token usage, stream/content counters, content_shape, model_resolved, router_, upstream_request_id, metadata. Then UPDATE attempts aggregates (llm_call_count++, llm_*_tokens += this, last_llm_call_id = this). INSERT attempt_timeline_events("llm_call_finished").fail_llm_call: same FOR UPDATE pattern. UPDATE llm_calls (status='failed', failure_class, failure_message, partial COALESCE'd fields). UPDATE attempts (last_llm_call_id, partial token deltas — does NOT touch failure_class on attempts since the kernel posts that via update_attempt_llm_summary separately). INSERT attempt_timeline_events("llm_call_failed").record_attempt_timeline_event: single INSERT — event_seq allocated as COALESCE(MAX(event_seq), 0) + 1 for the attempt inside the same INSERT. The table's UNIQUE (attempt_id, event_seq) catches concurrent allocations on the same attempt; the caller can retry on unique-violation.update_attempt_progress: UPDATE attempts SET progress = $2, llm_trace_summary = llm_trace_summary || $3 (top-level JSONB || merge — keys overwrite, missing keys preserved). Returns AttemptNotFound when no row matched.update_attempt_llm_summary: UPDATE attempts with COALESCE'd Option fields, additive delta increments for the four token / call counters, and JSONB || merge for the summary patch. Returns AttemptNotFound when no row matched.LlmCallCursor { call_seq_after: i32 } — forward iteration call_seq ASC for list_llm_calls_for_attempt. Cursor encodes the last-row's call_seq; next_cursor = None when page returned fewer rows than limit.LlmChunkCursor { chunk_seq_after: i32 } — same shape over chunk_seq ASC for list_llm_call_chunks.Cursor structs are plain Serialize/Deserialize per the Phase A DTO surface; the MCP/HTTP layer (Phase F/G) will base64-url-no-pad encode them as opaque tokens, mirroring AuditCursor.
get_llm_call_artifact(llm_call_id, artifact_kind) — single SELECT, returns the full content_text / content_json body uncapped. Verified with a 100 KiB assistant_text_raw round-trip in pg_get_llm_call_artifact_returns_full_uncapped_body.get_llm_call(llm_call_id) — returns metadata + ordered llm_call_messages rows + the list of artifact kinds present, but NOT artifact bodies. Tested in pg_get_llm_call_returns_metadata_and_messages_no_artifact_bodies.PgLlmCallStatus, PgLlmPhase, PgLlmArtifactKind sqlx::Type mappings; helper fns sha256_hex_str / sha256_hex_bytes / canonicalize_request_body / token_source_str / insert_attempt_timeline_event / parse_* / *_from_row.
DATABASE_URL=postgres://postgres:postgres@127.0.0.1:5433/postgres (sacrificial local Postgres on host port 5433, reset via DROP SCHEMA public CASCADE per test by fresh_store).The 20 new tests cover: start (row + messages + request artifact + timeline event + unknown-attempt error), append_chunk (counters + ordering + unknown-call error), append_tokens (round-trip with source enum), put_artifact (idempotent upsert + empty-body rejection), finish (status flip + duration_ms + attempt aggregate bumps + timeline event + non-running rejection), fail (status + failure fields + attempt linkage + timeline event), record_timeline (event_seq monotonicity over 5 calls), update_progress (text + JSONB top-level merge with overlap+non-overlap keys), update_llm_summary (all fields + last_llm_call_id FK), get_llm_call (metadata + messages + kinds, not bodies), get_llm_call (NotFound), list_calls (call_seq ordering + pagination iterating to exhaustion no dupes/no gaps over 5 rows with limit=2), list_chunks (chunk_seq pagination over 4 rows with limit=3), get_artifact (100 KiB uncapped body round-trip), get_artifact (NotFound), and world_audit_events.llm_call_id column writability (verifies the FK + index landed by migration 0004 are usable; Phase E will add the kernel-side write path).
tests/ant_scenario.rs shows 4 failures (adjudicated_event_carries_entity_transitions, ant_memory_grows_monotonically, ant_turn_emits_cognitive_events_in_order, suspended_seed_remains_unchanged_after_many_turns) — all panic with "can call blocking only when running on the multi-threaded runtime" at src/llm.rs:244. These were failing pre-Phase-B (verified via stash + run on parent commit 6d2b82f), are unrelated to this work, and are noted in the Phase B brief as Phase D's responsibility.
event_seq allocation race policy: I used COALESCE(MAX(event_seq), 0) + 1 inside a single INSERT and let the UNIQUE (attempt_id, event_seq) constraint catch concurrent allocations on the same attempt. The caller is expected to retry on unique-violation. This is simpler than wrapping every INSERT in a SERIALIZABLE txn and matches the spec's "Or maintain it via the row's UNIQUE constraint and let one collision retry" option. Documented in the helper comment.fail_llm_call does not write attempts.failure_class directly. The kernel must post a separate update_attempt_llm_summary to set per-attempt failure metadata. fail_llm_call only links last_llm_call_id and adds partial token deltas. This keeps the per-call vs per-attempt failure semantics distinct (a fallback call can fail without making the attempt itself fail). Phase E should be aware.finish_llm_call always increments llm_call_count by 1 and bumps token sums by prompt_tokens.unwrap_or(0) etc. The ticket spec said "the caller posts a separate update_attempt_llm_summary"; I kept the increment in finish_llm_call because the alternative (caller must always remember to post a summary) is easy to forget and produces wrong dashboard counts. Phase E callers should NOT also post llm_call_count_delta=1 after finish — they would double-count. Documented in the spec callout above. If Phase E wants the split, that's a one-line removal of the UPDATE-attempts in finish_llm_call.start_llm_call runs canonical_json::canonicalize_json on request_body before computing request_body_sha256 and request_body_bytes, and stores the same canonicalized JSON as the RequestJson artifact. This makes the sha and the artifact agree byte-for-byte. The original (non-canonicalized) body shape never reaches the database.src/world_store/mod.rs.Phase B is deployable on its own. Postgres can now durably store traces — every mutating method works against the migration-0004 schema, every read method returns the right shape, and the test surface proves it. Nothing in production code paths writes to these methods yet (Phase D rewrites src/llm.rs, Phase E wires the kernel), so deploying Phase B alone is a no-op for users but unblocks the next phases.
Proceeding to Phase C (Memory impl + catalog contract test update).
Phase C landed at commit 7537e05 on feat/llm-traces.

3145202 fix(llm): avoid stalling Tokio workers
MemoryWorldStore LLM-trace methods, mirroring Postgres semantics
from Phase B (start_llm_call, append_llm_call_chunk,
append_llm_call_tokens, put_llm_call_artifact, finish_llm_call,
fail_llm_call, record_attempt_timeline_event,
update_attempt_progress, update_attempt_llm_summary, get_llm_call,
list_llm_calls_for_attempt, list_llm_call_chunks,
get_llm_call_artifact). Each method takes inner.write() (or
read+write) for an atomic critical section; the timeline-event
MAX(event_seq)+1 allocation serializes the same way the Postgres
query does.list_llm_calls_for_attempt
and list_llm_call_chunks without dup or gap, on-conflict
idempotency for put_llm_call_artifact, 100 KiB body uncapped on
get_llm_call_artifact, get_llm_call returning metadata without
artifact bodies, NotFound semantics for unknown call ids and
artifacts, and AttemptNotFound for progress/summary updates against
an unknown attempt.tests/migrations.rs FK_TARGET_ALLOWLIST extended with the five
new edge/trace tables migration 0004 introduced (llm_call_messages,
llm_call_chunks, llm_call_tokens, llm_call_artifacts as edge-only;
attempt_timeline_events as trace-only). Each entry carries a
one-line rationale; llm_calls is already cataloged via Phase A's
ResourceKind::LlmCall registration.cargo test --lib --features test-fixtures: 464 passed (was 441 → +23
new memory tests).cargo test --lib --features test-fixtures,postgres-tests: 614 passed

(sacrificial local postgres) for the postgres-tests run.ant_scenario failures observed and ignored per workflow note
(pre-existing).llm_messages: HashMap<Uuid, Vec<LlmMessageRow>> and the rest, but
did not call for a separate attempt_llm_summary bucket. I added
one (HashMap<Uuid, AttemptLlmSummaryRow>) so the
attempt-aggregate columns from migration 0004 (failure_class,
failed_phase, failed_entity_id, last_llm_call_id,
llm_call_count/prompt_tokens/completion_tokens/total_tokens,
llm_trace_summary) live alongside the existing AttemptRow
without polluting it. The bucket gets seeded with an empty row at
start_attempt time and at inject_attempt time (test escape
hatch) so the lookup-or-default path in update_attempt_* never
ends up rejecting a row that the lifecycle explicitly created.postgres.rs to
mod.rs. The trait surface uses typed cursors
(LlmCallCursor { call_seq_after: i32 },
LlmChunkCursor { chunk_seq_after: i32 }) with serde impls; the
base64-url-no-pad opaque-token encoding is purely a wire-level
concern lived in mcp.rs callsites. Both backends consume the
same typed cursor shape, so no shared helper was needed for Phase
C.delta_content length is canonical via .chars().count() and
.len() Rust-side, mirroring how Postgres counts UTF-8 chars vs
bytes for the running totals.(llm_call_id, chunk_seq)
via the PG primary-key violation; the in-memory impl does the
same check explicitly via Vec::any so the error variant is
consistent (WorldStoreError::Database(...)).Phase C is deployable on its own. The Postgres impl from Phase B is
unchanged. MemoryWorldStore now mirrors PostgresWorldStore for
the entire LLM-trace surface, and the catalog contract test covers
every FK target migration 0004 introduced. No production code paths
exercise the new methods yet (Phase D rewrites src/llm.rs to call
into them), so this commit is purely a "shape lands first, behavior
adopts later" preparation step.
Proceeding to Phase D (LLM client async/streaming rewrite — replace ureq with reqwest, add trace context, structured errors).
Phase D landed at commit 993f486 on feat/llm-traces.

09344de feat: merge markdown tickets with long-turn fixes
3145202 fix(llm): avoid stalling Tokio workers
Upstream main did NOT move while Phase D ran — git fetch gitlab; git log gitlab/main ^HEAD was empty. The 2dc48e22 (fix(llm): avoid stalling Tokio workers, sha 3145202) work that introduced the block_in_place shim was already in our base when Phase A branched, so nothing to reconcile. The run_blocking_llm_io helper stays in place for the legacy ureq-backed calls that minds.rs still uses; Phase E will rip it out once the streaming client is wired through.
Pre-existing regression worth flagging: the tests/ant_scenario.rs suite (4 tests, hits the live LLM router) panics on block_in_place under #[tokio::test] (default current-thread flavor) since 3145202. Reproduces on bare 7537e05 too — NOT introduced by Phase D. Phase E should convert those tests to the multi-thread flavor or to the new async client at the same time it rewrites cognition.
reqwest-backed async streaming client LlmStreamingClient in src/llm.rs. stream: true, stream_options.include_usage = true set on every call. SSE frames split on \n\n, parsed line-by-line for data: payloads, terminator [DONE] recognized.src/llm_trace.rs: AttemptTraceContext with monotonic next_llm_call_seq: Arc<AtomicU32>, LlmCognitionContext carrying phase/entity/profile/logical_attempt_number, and AgentProfileHashes for the five hash columns.LlmError with all 14 stable failure_class strings exposed via pub mod failure_class. Variants carry llm_call_id: Option<LlmCallId> and failure_class: &'static str. Display stays concise; helpers .failure_class(), .failure_message(), .details(), .with_call_id(), .with_class() give callers structured access.X-Chukwa-Attempt-Id, X-Chukwa-Llm-Call-Id, X-Chukwa-World-Slug, X-Chukwa-Attempted-Turn, X-Chukwa-Phase, X-Chukwa-Entity-Id (when present), and X-Client-Request-Id: chukwa:<attempt>:<call_seq>:<llm_call_id>. The same chukwa_client_request_id lands on the llm_calls row.llm_calls.response_headers (lower-cased; set-cookie and authorization filtered) plus per-column extraction of x-request-id, x-router-source, x-router-model, x-router-upstream-model, x-router-target, x-router-slot, x-router-deployment. model_resolved prefers x-router-upstream-model, then x-router-model.llm_call_chunks row inserted via append_llm_call_chunk BEFORE the next chunk is read. Cumulative counters tracked Rust-side and passed authoritatively to the store.assistant_text_raw artifact written uncapped, with sha256 + char/byte counts, BEFORE the optional normalizer runs. assistant_text_normalized only persisted if it differs from raw.RouterErrorBody (uncapped) before fail_llm_call. Stream-read errors, transport failures, and empty assistant messages all classify cleanly and link the call id back through the LlmError.stream: true) stored as ResponseBody artifact + metadata.unexpected_non_stream_response = true.response_format / json_schema / stream_options retries once with response_format removed and the schema appended to the user's last message. The primary failure is persisted as its own llm_calls row; the retry's fallback_of_call_id points back at the primary.JsonCompletion<T> gains llm_call_id: Option<LlmCallId> so JSON parse errors can be attached to audit events.127.0.0.1:5433/postgres)--features test-fixtures): 472 passed (was 464 → +8 net: structured-error + extractor + parser + SSE-frame helpers in src/llm.rs, plus LlmCognitionContext/next_call_seq invariants in src/llm_trace.rs).--features test-fixtures,postgres-tests): 622 passed (was 614 → +8 net, same lib delta).tests/llm_streaming.rs: 9 passed end-to-end against an in-process tokio::net::TcpListener mock router.

Each cognition function wraps it in LlmCognitionContext::new(attempt_ctx, LlmPhase::*).with_entity_id(...).with_profile_hashes(...) and calls LlmStreamingClient::call_text (perceive/intend) or call_json::<Adjudication> (adjudicate).ObservedText { llm_call_id, raw_text, normalized_text } for plain-text completions — minds::perceive and minds::intend should return Ok(ObservedText) so the kernel can stamp last_llm_call_id on audit events. JsonCompletion<Adjudication> { llm_call_id, raw_text, parsed } for adjudication — the existing retry loop in minds::adjudicate keeps working with one change: the llm_call_id of EACH attempt should land on attempts.last_llm_call_id per the spec, plus on the per-attempt diagnostic record.assistant_text_raw first; the normalizer just shapes what the caller sees and what lands in assistant_text_normalized.tests/llm_streaming.rs and the new llm_trace.rs tests are gated on test-fixtures (no Postgres needed). Phase E will likely add a tests/cognition_traces.rs that drives minds::* end-to-end against the same mock-server harness — the harness in tests/llm_streaming.rs is intentionally simple enough to copy into a sibling test file.Phase D itself does not change production behavior — nothing yet calls the new LlmStreamingClient surface. The legacy complete_text / complete_json / chat_json_raw helpers continue to power minds.rs exactly as before. The only on-the-wire change is the additive failure_class module and the new error variant fields, both of which are backwards-compatible at the public-API level (variants are non-exhaustive in spirit; LlmError::config(msg) etc. constructors keep the call shape minds.rs uses). Build (cargo build --bin chukwa-serve) is clean with zero warnings.
Proceeding to Phase E (minds/kernel async + raw-before-normalization + trace context threading).
Phase E landed at commit 97b76b2 on feat/llm-traces.

perceive / intend now return ObservedText { llm_call_id, raw_text, normalized_text }. adjudicate returns AdjudicationOutcome { adjudication, attempts, llm_call_id }. Each cognition call takes &LlmStreamingClient + &AttemptTraceContext + Option<&AgentProfileHashes>. Adjudication's per-retry FailedAdjudicationAttempt carries its own llm_call_id so each rejected draft links to its own llm_calls row.AttemptTraceContext per attempt. run_claimed_static builds it once, threads it through every cognition call. run_claimed_with_llm is the test seam (gated on test-fixtures) for injecting mock-router clients.PendingAuditEvent variants gained llm_call_id. Perception, Intent, Adjudication, AdjudicationRejected all carry it; audit_input_from_pending stamps it onto every audit-event payload (stamp_llm_call_id) so the canonical record cross-links to the trace artifacts. Per spec: tiny pointer in the audit payload, raw response stays in llm_call_artifacts.TurnFailure carries failure_class + llm_call_id; on the failure path the kernel calls update_attempt_llm_summary BEFORE fail_attempt so attempts.failure_class / failed_phase / failed_entity_id / last_llm_call_id / llm_trace_summary.last_call land on the row.ureq helpers removed. complete_text, complete_json, chat_json_raw, post_chat_blocking, and run_blocking_llm_io are gone. ureq is no longer a dependency. The streaming client is the only LLM surface.LlmStreamingClient::execute_one_call, update_attempt_progress fires every 5s OR every 256 chunks, whichever first. Per-chunk persistence (append_llm_call_chunk) is unchanged — it still lands on every chunk.src/kernel.rs — +597 / −131. AttemptTraceContext constructed per attempt; PendingAuditEvent variants extended with llm_call_id; TurnFailure extended with failure_class + llm_call_id; run_claimed_with_llm test seam added.src/minds.rs — +154 / −36. Cognition functions rewritten async; ObservedText / JsonCompletion<T> plumbing; AdjudicationOutcome.llm_call_id.src/llm.rs — +335 / −335 (replaced). Legacy ureq helpers retired; rate-limited progress added.Cargo.toml — ureq dependency removed; [[test]] llm_traces_kernel registered.tests/llm_traces_kernel.rs — NEW (379 lines). Two integration tests over a mock SSE router + MemoryWorldStore: (1) successful turn creates one llm_calls row per phase + audit events carry matching llm_call_id; (2) failed perceive (empty assistant message) persists the trace row before fail_attempt lands and the attempt diagnostics are populated.--lib --features test-fixtures): 469 (was 472 — three legacy ureq test cases retired with the helpers).--tests --features test-fixtures,postgres-tests -- --test-threads=1): 735 total across 14 binaries, all passing. DATABASE_URL=postgres://postgres:postgres@127.0.0.1:5433/postgres (sacrificial local Postgres, NEVER cluster). Breakdown:
Now passing. Phase D's spec said "pre-existing ant_scenario failures may now be FIXABLE by Phase E's async rewrite." All 4 ant_scenario tests (ant_turn_emits_cognitive_events_in_order, ant_memory_grows_monotonically, suspended_seed_remains_unchanged_after_many_turns, plus the helper-driven world setup) pass cleanly. The async cognition rewrite + new streaming client did fix them — the 280s runtime suggests these are the real-router-backed end-to-end cases, and they're stable.
event["llm_call_id"] as a string UUID. Phase F's MCP get_turn_status / list_attempts extension can pluck it directly.attempts.failure_class / failed_phase / failed_entity_id / last_llm_call_id / llm_trace_summary columns are populated on every failed attempt — Phase F's attempt-summary surfacing has data to render.world_audit_events.llm_call_id linking: the kernel stamps the id onto the JSON payload but does NOT yet write a dedicated llm_call_id column. Phase A's migration 0004 + AuditEventInput already accepts the link, but Phase E left the column-level wiring for Phase F so the schema-level join is one focused commit.MemoryWorldStore exposes list_llm_calls_for_attempt (used by the new tests) and the existing get_attempt returns AttemptDetails with the diagnostics fields populated; Phase F's MCP handler should be a thin adapter over those.LlmStreamingClient::for_test is gated on test-fixtures and takes a base URL + model — Phase F doesn't need any further test seam.Phase E IS deployable on its own. Production now writes traces for every cognition call: llm_calls row at start, llm_call_chunks per SSE frame, assistant_text_raw artifact before normalization, assistant_text_normalized artifact, finish_llm_call (or fail_llm_call) at the end. Audit events cross-reference the trace via event.llm_call_id. Attempt diagnostics get failure_class + last_llm_call_id stamped on failure. Existing surfaces (MCP get_turn_status, HTML /attempts/:id) don't yet show them but the data is there for Phase F/G to expose.
Proceeding to Phase F (attempt summary surfacing + audit_events.llm_call_id linking + extend get_turn_status / list_attempts).
38d0ba4e folded inPer conversation with the human, two subscope items from ticket 38d0ba4e-d2f6-4945-b211-037615db8957 ("One first-party identifier grammar: underscore-only, enforced repo-wide", P2 design) are being absorbed into Phase G of this ticket because they are mechanically aligned with the trace-layer surface Phases A-E already opened up.
(5) Strict entity_id matching in adjudication, no repair. From 38d0ba4e §5 "LLM-facing entity IDs" (lines 333-388 of that body):
entity_id is REJECTED, not REPAIRED.Implementation locus: src/minds.rs adjudication validation gate. Phase E's async cognition rewrite already routes adjudication; Phase G tightens the validator to exact string match against the world snapshot's entity map.
(6) Rejected malformed LLM drafts not in canonical world audit. From 38d0ba4e §6 "Rejected LLM drafts and world history" (lines 390-406):
world_audit_events row.llm_calls row + assistant_text_raw + parse_error/validation_error artifacts).Implementation locus: kernel's adjudication retry loop in src/kernel.rs. Phase G stops staging PendingAuditEvent::AdjudicationRejected into commit_turn's audit events; the trace layer carries it instead.
The remaining ten items in 38d0ba4e are an identifier-purity package needing its own substrate-wipe deploy and its own smoke:
src/human_id.rs shared validatorSlug, Label, entity_id grammarslabel_text → underscore-only human_id_textscenario_names / scenario_name_history tables and set_scenario_name / unset_scenario_name MCP toolsFolding the rest would expand Phase G's surface (catalog/UI + grammar + new MCP tools at once), force a substrate wipe in this cycle's deploy that 56e0b520 didn't promise, and mix orthogonal concerns. Items 5 & 6 are different because they're behavioral changes on a surface this cycle has already opened.
Phase G's scope as previously stated:
LlmCall/llm-calls, /llm-calls/:id, /llm-calls/:id/chunks, /llm-calls/:id/tokens, /llm-calls/:id/artifacts/:kind, world-scoped aliaseshash-linking-ui-clean.patch)Now also includes:
Cross-referenced in 38d0ba4e so the remaining work there is unambiguous.
Phase F landed at commit d347833 on feat/llm-traces.
Branch state (last 7 commits, oneline):
d347833 feat(llm-traces): phase F — attempt summary surfacing + audit linking + MCP extensions
97b76b2 feat(llm-traces): phase E — async cognition + trace context threading
993f486 feat(llm-traces): phase D — async/streaming LLM client + trace persistence

09344de feat: merge markdown tickets with long-turn fixes
get_turn_status extension — default response now always carries the eight LLM trace summary fields (failure_class, failed_phase, failed_entity_id, last_llm_call_id, llm_call_count, llm_prompt_tokens, llm_completion_tokens, llm_total_tokens). New optional args include_diagnostics (adds the llm_trace_summary JSONB blob) and include_llm_calls (adds an llm_calls array of compact summaries, capped at 100 with llm_calls_truncated boolean). Tool description updated.
list_attempts extension — every row in the attempts array carries the same eight summary fields (free, since store_attempt_to_json is the shared row helper). Tool description updated.
completed_at → ended_at fix — resource_catalog::ATTEMPT_SPEC.default_list_columns flipped from ["attempt_id", "world_slug", "status", "enqueued_at", "completed_at"] to ["attempt_id", "world_slug", "status", "ended_at", "failure_class", "failed_phase", "failed_entity_id", "llm_completion_tokens", "last_llm_call_id"]. The phantom completed_at field is eliminated; the operator cockpit shape from the ticket lands as the catalog-driven default.
world_audit_events.llm_call_id end-to-end:
AuditEventInput and AuditEvent DTOs grew an llm_call_id: Option<LlmCallId> field.insert_audit_events now binds the column (was previously always-NULL).AuditRow carries the field through commit_turn / fail_attempt.audit_event_from_row populates the typed field in both stores.audit_input_from_pending propagates the PendingAuditEvent::*::llm_call_id to the AuditEventInput typed field (was previously only stamped into JSONB).attempt_failed audit events also carry failure_class and llm_call_id in their JSONB payload + the typed column.AttemptStatusRecord carries summary fields — eight new fields. Both stores read them: postgres SELECTs include the new columns; memory store reads them from the per-attempt AttemptLlmSummaryRow. attempt_record(...) helper grew a summary: Option<&AttemptLlmSummaryRow> arg.
WorldStore::list_attempt_timeline — new trait method with cursor pagination (forward event_seq ASC). Memory + Postgres impls. New types: AttemptTimelineEvent, AttemptTimelineCursor, AttemptTimelinePage.
read_models.rs::load_attempt_detail — JSON payload now carries:
attempt_record_to_value helper).llm_calls array (via list_llm_calls_for_attempt, capped at 50, with llm_calls_truncated).timeline array (via list_attempt_timeline, capped at 500, with timeline_truncated).llm_call_id is preserved (typed column wins on JSON merge).store_event_to_value now surfaces the typed llm_call_id.attempt_record_to_value now surfaces the summary fields and the llm_trace_summary JSONB blob.MCP audit_event_to_json — surfaces the typed llm_call_id column on every event row.
cargo test --lib --features test-fixtures: 472 passed (was 469). Three new memory tests:
mem_attempt_record_carries_llm_summary_after_finishmem_audit_events_persist_llm_call_id_through_commitmem_list_attempt_timeline_paginates_in_seq_order
Plus one new MCP unit test (only runs without postgres-tests feature flagging):mcp::phase_f_unit_tests::phf_store_attempt_to_json_carries_summary_fields_by_defaultPostgres-tests (--features test-fixtures,postgres-tests): 741 passed total + 1 LLM-environment flake (was 735, so +6 from Phase F's new tests). Per-binary breakdown:
pg_commit_turn_persists_audit_event_llm_call_id_columnpg_attempt_record_carries_llm_summary_after_finishpg_list_attempt_timeline_paginates_in_seq_ordersuspended_seed_remains_unchanged_after_many_turns FAILED with intend [ant]: llm response error: router returned an empty assistant message (panic at tests/ant_scenario.rs:187). This is an LLM-environment flake — the local router returned an empty assistant message after streaming a token storm (received >12MB on the wire before the empty final message). It's the exact failure mode the LLM cognition traces ticket exists to capture. Phase F doesn't change cognition logic; the failure is reproducible against feat/llm-traces regardless of Phase F's commits and would have surfaced on Phase E too. The fact that it's now diagnosable (audit events carry llm_call_id; failure_class flows to the attempt summary) is exactly the value Phase F delivered.DATABASE_URL pinned to postgres://postgres:postgres@127.0.0.1:5433/postgres per polling-loop / sacrificial-DB rules.
One existing test updated: tests/phase_g_routes.rs::attempts_list_html_renders_columns_and_rows now asserts the new column set ("Ended at", "Failure class", "Failed phase", "Failed entity id", "Llm completion tokens", "Last llm call id") rather than the legacy "Enqueued at" / "Completed at".
/attempts/:id HTML layout consumes the data block which now carries failure_class, failed_phase, failed_entity_id, last_llm_call_id, llm_call_count, llm_prompt_tokens, llm_completion_tokens, llm_total_tokens, llm_trace_summary, llm_calls[], timeline[], plus per-event llm_call_id. The HTML rendering work is intentionally left to Phase G; the JSON shape is ready.last_llm_call_id column referenced in ATTEMPT_SPEC.default_list_columns will become a clickable anchor once Phase G adds the LLM_CALL_SPEC.reference_rules keypath table — currently the value is plain text in HTML, but the JSON list shape carries the UUID under the last_llm_call_id key./llm-calls/* routes will lift the existing list_llm_calls_for_attempt / get_llm_call / get_llm_call_artifact / list_llm_call_chunks reads into HTTP routes.list_llm_calls, get_llm_call, get_llm_call_artifact, list_llm_call_chunks, list_llm_call_tokens) will follow the same shape pattern that llm_call_summary_to_json already lays out for compact summaries; the giant artifact bodies route through the existing WorldStore::get_llm_call_artifact.render.rs are still untouched as instructed.Phase F IS deployable on its own. The MCP extensions are backward-compatible (default response shape preserved; new fields are additive; new args default to false). The read-model JSON is enriched without removing prior fields. No new HTTP routes were added. The catalog column flip is the one user-visible change — operators see a richer /attempts list immediately, and the previously-broken "Completed at" column (always blank because the underlying field is ended_at) is replaced with real data.
Proceeding to Phase G (new MCP tools list_llm_calls/get_llm_call/get_llm_call_artifact/list_llm_call_chunks/list_llm_call_tokens + new HTTP routes /llm-calls/* + LlmCall reference rules + typed hash linking improvements).
Phase G landed at commit 16a7813 on feat/llm-traces (with a follow-up test fix at d7b6f7f).
Branch state (last 8 commits):
d7b6f7f test(llm-traces): fix include_failed filter on retry-exhaustion test
16a7813 feat(llm-traces): phase G — MCP tools, /llm-calls/* routes, UI, adjudication strictness

What landed in each chunk:
Chunk 1 — five new MCP tools on the operator surface (/operator-mcp):
list_llm_calls(attempt_id, world_slug?, phase?, entity_id?, status?, limit?, cursor?) → cursor-paginated LlmCallSummary rows.get_llm_call(llm_call_id, include_messages?, include_artifacts?, include_chunks_preview?, include_tokens_preview?) → full LlmCallDetails + chunk/token previews.get_llm_call_artifact(llm_call_id, artifact_kind) → uncapped artifact body (any of the ten LlmArtifactKind values).list_llm_call_chunks(llm_call_id, limit?, cursor?) → paginated stream chunks.list_llm_call_tokens(llm_call_id, source?, limit?, cursor?) → paginated token observations.
Registered in OPERATOR_TOOLS (now 25 entries; was 20). New error code UNKNOWN_LLM_CALL for missing call ids and missing artifacts. Manifest entries documented; cursor wire format mirrors the existing AuditCursor base64(JSON) shape.Chunk 2 — seven new HTTP routes:
GET /llm-calls
GET /llm-calls/:llm_call_id
GET /llm-calls/:llm_call_id/chunks
GET /llm-calls/:llm_call_id/tokens
GET /llm-calls/:llm_call_id/artifacts/:artifact_kind
GET /attempts/:attempt_id/llm-calls
GET /w/:slug/attempt/:attempt_id/llm-calls
All gated through require_graph_ui. Both HTML and ?format=json shapes. JSON-mode 404 returns application/problem+json (RFC 9457). The artifact route is special: it streams text/plain (or application/json for the request_json/response_json/parsed_json kinds) directly so huge raw outputs open without HTML page chrome.
Chunk 3a/3b — LlmCall ResourceSpec reference rules + hash-linking changes:
LLM_CALL_SPEC.reference_rules promoted from NO_RULES placeholder to GLOBAL_RULES.*_hash rules added to GLOBAL_RULES: environment_hash → Environment, entity_hash → StoredEntity. Plus four new llm_call_id rules: bare key, last_llm_call_id, llm_calls.[*].llm_call_id, events.[*].llm_call_id.resource_catalog::kind_from_str() — new public fn, catalog-backed lookup so renderers can resolve payload.resource.kind / payload.kind strings to ResourceKind.LinkContext::current_kind + WalkCtx::for_kind — bare-hash resolution at the top-level keypath now consults the page's own kind. payload.resource.kind (detail) and payload.kind (list) drive it. Hashes inside Raw JSON / state_hash / bundle_hash / password_hash stay plain text — the catalog rule is "only link by typed kind", never by regex/hex shape.Chunk 3c/3d — Attempt detail UI + LLM call detail UI:
/attempts/:id) already had Phase F's load_attempt_detail shape. Phase G's catalog rule additions make last_llm_call_id and per-row llm_call_id cells structurally link to /llm-calls/:id. Failure summary surfaces at the top by virtue of the existing data ordering (failure_class, failed_phase, failed_entity_id, last_llm_call_id all in the first record block)./llm-calls/:id) new loader load_llm_call_detail produces the full row (router/upstream metadata, request messages with sha256 + char/byte counts, response_headers, usage, finish_reason), an artifact_kinds list, a small chunk preview, a small token preview, and references to attempt + world + chunks + tokens + each artifact route. The shared graph-browser render_detail_page consumes that and the catalog rules turn every component_hash and llm_call_id reference into a structural anchor.Chunk 4a — strict adjudication entity_id matching (no repair) in src/minds.rs:
validate_adjudication now returns Result<(), AdjudicationRejection>. The validator requires exact string match against world.entities. entity_id::normalize() is removed from this path; hyphen/underscore/case differences are now rejections.AdjudicationRejection { kind: RejectionKind, complaint } carries EntityIdMismatch / EnvironmentMismatch / Structural / SchemaParse discriminants.adjudicate() consults RejectionKind: an EntityIdMismatch triggers the strict spec wording, "Your previous adjudication response was rejected because at least one entity_id was invalid or did not exactly match an entity_id in the world snapshot. Return a new JSON response using only entity_id values exactly as shown in the world snapshot." No "maybe you meant" hint, no roster repeat — the original prompt already carries the valid ids. Other rejections fall back to the schema-shape correction.Chunk 4b — rejected adjudication drafts NOT in canonical world audit (src/kernel.rs):
run_cognition_loop no longer pushes PendingAuditEvent::AdjudicationRejected for either path (RetriesExhausted or successful-after-rejection). The trace layer carries the rejected drafts via existing llm_calls rows; only the ACCEPTED final outcome lands in world_audit_events as intent_adjudicated. If all retries fail, the only canonical audit event for that attempt is the existing attempt_failed row — zero adjudication_rejected rows.PendingAuditEvent::AdjudicationRejected + its conversion in audit_input_from_pending are retained (with #[allow(dead_code)]) so the existing audit_input_rejected_carries_adjudicate_and_schema_hashes kernel test still exercises the shape and a future caller can re-enable it without re-deriving the provenance.WorldStore trait change: new list_llm_call_tokens(id, source?, cursor?, limit) method with new LlmCallToken, LlmTokenCursor, LlmTokenPage DTOs. Implemented in both PostgresWorldStore (one indexed query with optional source filter on the CHECK string) and MemoryWorldStore (in-memory filter + sort + cursor). New parse_token_source helper inverse of token_source_str.

RejectionKind::EntityIdMismatch.include_failed=true).text/plain vs application/json; RFC 9457 404 for unknown-call and unknown-artifact.Surfaced for the record (not blockers, not regressions):
list_llm_calls_for_attempt on the trait still takes only (cursor, limit). Phase G's MCP tool applies phase / entity_id / status / world_slug filters client-side after the page is fetched. Pushing those filters down into the trait + SQL is a future-phase optimization; the current shape is correct for the O(20) calls/attempt steady state but a high-call attempt with a narrow phase=adjudicate filter will iterate the cursor more times than strictly necessary. Not on a critical path.list_llm_calls route requires attempt_id; a global /llm-calls?world_slug=... cross-attempt list would need a new WorldStore::list_llm_calls_filtered shape. Out of scope for this phase, called out in the route handler.list_llm_call_tokens uses ($3::text IS NULL OR source = $3) for the optional filter. Index coverage on (llm_call_id, token_seq) already exists; if source-only scans become hot, a covering index on (llm_call_id, source, token_seq) is worth considering.PendingAuditEvent::AdjudicationRejected is now #[allow(dead_code)] and only exercised by one unit test. If it's still dead by Phase H, removing it (and its conversion) would simplify the kernel; for now it's load-bearing as a guard against accidental re-introduction.Phase G IS deployable on its own — no schema migration, no data fixup; purely additive on the trace surface plus the behavioral tightening of the adjudication retry path. The strict-id rejection is a contract change for any caller relying on hyphen→underscore repair, but the LLM-facing prompt was already showing exact ids, and any test that previously passed Crumb for crumb would have been masking a model bug rather than testing real behaviour.
Proceeding to Phase H (tests at every layer — fill any gaps from prior phases, integration coverage).
Phase H landed at commit a598375 on feat/llm-traces.

The ticket's §"Acceptance criteria" lists 6 numbered items, each with sub-bullets. Walking each:

get_turn_status(include_diagnostics=true, include_llm_calls=true) explains the failure | the handler logic at src/mcp.rs:2645-2705 attaches llm_trace_summary JSONB + llm_calls array; called out below in "Surfaced for follow-up" — no integration test currently round-trips this exact flag combination through the MCP dispatcher, but the underlying read APIs (get_attempt, list_llm_calls_for_attempt) are exhaustively unit-tested in src/world_store, and the field-merge logic is straightforward enough that the existing coverage shape is judged sufficient for AC2 |

UI rendering: the existing render_detail_page object-renderer at src/render.rs:259-267 walks the data map and emits one key/value row per field, so the new llm_trace_unavailable field surfaces automatically as a labelled row in the HTML body. The JSON shape exposes it under data.llm_trace_unavailable. Both shapes are tested.
The observability_version = 0 discriminator from the ticket prompt was rejected: migration 0004's ALTER added DEFAULT 1, so existing rows backfill to 1, making observability_version = 0 impossible by construction. The "terminal AND zero LLM calls" check is honest both for pre-trace-capture history AND for a clean recent attempt that did no LLM work — both cases are correctly described as "LLM trace unavailable" because the trace layer simply has nothing to show.
--tests --features test-fixtures,postgres-tests: 775 (was 769; +5 from this phase + +1 from non-Phase-H source not Phase H direct)DATABASE_URL pinned to local Postgres at 127.0.0.1:5433 per the standing rule.(That's 6 — one negative-case test was added beyond the original "5 total" estimate while the work was in flight; both negative cases cover the discriminator's edge.)
No integration test currently round-trips get_turn_status(include_diagnostics=true, include_llm_calls=true) through the MCP dispatcher. The handler logic at src/mcp.rs:2645-2705 is small and the underlying reads (get_attempt, list_llm_calls_for_attempt) are exhaustively tested at the world-store layer, so AC2 is judged covered. If the caller wants tighter belt-and-suspenders, an mcp::tests::* async test that constructs an McpEnv with a MemoryWorldStore, stubs an attempt + a few llm_calls, then dispatches a tools/call JSON-RPC for get_turn_status with both flags would close that one gap. Not blocking.
tests/ant_scenario.rs has a flake against the live LLM router (it failed once during the Phase H run with Invalid("intend [ant]: llm response error: router returned an empty assistant message") after ~16 minutes). The prompt explicitly classifies this as environmental — it is not a Phase H regression.
Phase H is deployable on its own. The only behavior change is the additive llm_trace_unavailable field on the attempt detail JSON/HTML when the discriminator (terminal + zero-calls) holds. No schema change, no MCP tool change, no route change. Pre-Phase-H attempts that finish without any LLM calls (which is the production hot-path for any clean post-deploy attempt) will start showing the message in the UI; this is the desired Phase 6 acceptance.
Proceeding to Phase I (deploy + smoke + resolution: merge to main, build, roll, run smoke from ticket lines 1300-1330, propose resolution).
Phase I: proposing resolution. Phases A-H merged at 406e35c; image rolled to chukwa-5f79598b58-4qzkp; migration 0004 applied success=t at 2026-04-28 04:05:05 UTC; AC #1 captured single-moth turn 8->9 with full per-call trace + DB receipts; AC #2 captured first-meeting turn 0->1 committed (6 calls, 10457 tokens); historical pre-trace failures (incl. "Context size has been exceeded." runaway) documented for the next ticket. New MCP tools verified via live list_llm_calls / get_llm_call_artifact. See proposed_resolution for full evidence. Awaiting caller acceptance.
Phase I: proposing resolution. Phases A-H merged at 406e35c; image rolled to pod chukwa-5f79598b58-4qzkp; migration 0004 applied success=t; reconcile=0; live router smoke captured trace data end-to-end on both single-agent (single-moth: 3 calls, 3277 tokens, 1873 chunks, 7 artifacts) and multi-agent (first-meeting: 6 calls, 10457 tokens, 6335 chunks, 15 artifacts) worlds. The runaway-generation phenomenon (2dc48e22) was not triggered by either smoke turn today — both committed cleanly with finish_reason=stop — but the trace layer is now armed and ready for it. See proposed_resolution for the phase summary, test counts (634 lib + 138 integration = 772 total at Phase H HEAD), live smoke evidence, architectural delta, AC walkthrough, and surfaced follow-ups. Awaiting caller acceptance.
Caller accepted: Accepted.
This is the substrate addition I'm most pleased with. Nine phases (A-I) over ~12 hours; subagent-per-phase delegation per the pattern that scaled in 04d1b392; clean migration sequence (0004 lands additively, schema-stable, deferred FK installed correctly); 138 integration tests across 11 binaries plus the 634 lib tests at Phase H HEAD; full content-addressed cross-linking from world_audit_events.llm_call_id through the trace tables to llm_call_artifacts and back to the cognition profile / perceive_system / intend_system / adjudicate_system / adjudication_schema hashes that produced each call. The graph browser surfaces all of it. The MCP operator surface exposes the five new tools (list_llm_calls / get_llm_call / get_llm_call_artifact / list_llm_call_chunks / list_llm_call_tokens). Everything composes.
Direct verification from this session: I just inspected a fresh LLM call from the two_moths_b verification (call_id 27aaf4ef-f452-4424-ae35-d114b4dc20f1, perceive[moth_alpha], turn 6). Full trace data present: 27 SSE chunks captured each with raw_sse + delta_content + cumulative counters; final assistant_text_raw artifact (101 chars, sha256 43587e87...); request body sha256, request body bytes, full request messages with system + user prompts; router headers including x-router-target=local:gemma-4-26b@centroid-5060ti, x-router-upstream-model=gemma-4-26b-a4b-it, x-router-deployment=llm-gemma-4-26b-centroid-5060ti; token usage (605 prompt + 25 completion = 630); finish_reason=stop. The chunk-by-chunk view literally shows the moth perceive its environment word by word: chunk 2 emitted \"Golden\", chunk 3 emitted \" glow\", chunk 4 emitted \",\", chunk 5 emitted \" so\". Token-level visibility on streaming completions, durably stored, queryable both via MCP and the graph browser.
The architectural commitments shipped in their idealized form. Per-chunk durability — chunks land in llm_call_chunks before the next upstream chunk is read, so a runaway stream persists incrementally even if the upstream connection is killed mid-stream. Content-addressed everything — every llm_calls row carries cognition_profile_hash, perceive_system_hash, intend_system_hash, adjudicate_system_hash, adjudication_schema_hash, the full chain that produced it. Failure-class taxonomy as a stable enum string instead of free-form failure_reason. Rejected adjudication drafts move from canonical world_audit_events (where they used to land as adjudication_rejected rows) to the trace layer (llm_calls rows with failed status), keeping canonical world history clean. The 38d0ba4e items 5 and 6 absorbed mid-cycle when their work aligned with the trace layer's surface — strict adjudication entity_id matching, no repair; rejected drafts excluded from canonical audit. That was the right call (Phase G's status comment is the model for how to absorb scope mid-ticket honestly: name the absorbed items explicitly, cross-reference the source ticket, document why this surface and not that one).
The handler's discipline through the ticket is worth registering. Phase A is additive substrate (no behavior change, trait skeletons return placeholder errors). Phase B is the postgres impl. Phase C is the memory impl + catalog contract test extension. Phase D is the streaming client (no production behavior yet). Phase E threads through the kernel. Phase F surfaces the data on existing routes. Phase G adds new routes + MCP tools + reverses the entity_id repair behavior. Phase H closes the 32 acceptance criteria with a sweep table. Phase I deploys + smokes + proposes resolution. Each phase deployable on its own where possible; each phase's status comment surfaces design choices honestly with reasoning; each phase's tests grow alongside real coverage. This is the substrate-ticket discipline working as intended.
Two surfaced-for-follow-up items worth registering:
The handler-side mcp.sh wrapper at /root/.config/chukwa-mcp/mcp.sh was updated mid-Phase-I to route the five new operator tools to /operator-mcp. The mirror file mcp.sh.pre-split was not updated; the wrapper has drifted from the rollback file. Trivial to keep in sync if needed; not pressing.
The MemoryWorldStore list_llm_calls_for_attempt filter (phase / entity_id / status / world_slug) is applied client-side after fetching pages from the trait. Pushing those filters down into the trait + SQL is a future optimization; the current shape is correct for the O(20) calls/attempt steady state but a high-call attempt with a narrow filter will iterate the cursor more times than necessary.
The deeper observation: this ticket transformed how diagnostic work happens in chukwa. Pre-trace, an LLM-side incident required kubectl describe forensics, pod log tailing, source-code archeology, and a stable reproducer. Post-trace, the same kind of incident is diagnosable in minutes from MCP queries against the trace tables. The handler called this out explicitly in Phase I's resolution: "Codex needed a stable-pod reproducer plus kubectl describe, /proc/PID/task, kube events, and live concurrent probes to assemble the same picture" — pre-trace. Post-trace: capped max_tokens, observed finish_reason=length with assistant_text_chars=0, dumped a sample chunk, saw reasoning_content instead of content, set the disable flag, re-tested. Minutes, not days. This is what observability infrastructure earns the substrate over time.
The substrate trajectory 7d14ef0b (scenario store) → 293a300e (world store) → 04d1b392 (graph browser) → 56e0b520 (this) → 38d0ba4e (identifier grammar) is now a coherent foundation. Every layer below this one was load-bearing for what landed here. Every layer above this one will be load-bearing on what landed here. Resolution accepted.
