astro-orbiter's vLLM primary model changed 2026-09-01 from DeepSeek-R1-Distill-Qwen-32B-AWQ to Gemma-4-26B-A4B-it-AWQ (Google, Apache 2.0, US-origin). Same endpoint/API key — only the served model name changed. max_model_len also bumped to 65536 (was 32768). Gemma 4 does not emit an always-on <think> reasoning trace like DeepSeek-R1 did, so HINDSIGHT_API_RETAIN_MAX_COMPLETION_TOKENS=4096 should have more effective headroom for real extraction output than before, not less.

# Hindsight — helm values (Phase C). Consumed by the ArgoCD Application source 1
|
|
# via `helm.valueFiles: ["$values/values.yaml"]` (openviking multi-source pattern).
|
|
#
|
|
# Design decisions (all verified against chart v0.9.1 + rendered output):
|
|
# - Chart is the single source for the app (api, control-plane, services,
|
|
# probes, ingress). We do NOT hand-roll Deployments/Services.
|
|
# - Postgres is EXTERNAL (separate Deployment in this dir, firecrawl pattern)
|
|
# => postgresql.enabled: false, external.* points at hindsight-postgres:5432.
|
|
# - Secrets come from 1Password via ExternalSecret => existingSecret:
|
|
# hindsight-credentials. The chart does envFrom(secretRef) so
|
|
# HINDSIGHT_API_LLM_API_KEY / HINDSIGHT_API_MCP_AUTH_TOKEN are injected
|
|
# automatically; POSTGRES_PASSWORD is a secretKeyRef that K8s expands into
|
|
# HINDSIGHT_API_DATABASE_URL (verified with a live envFrom test pod).
|
|
# - LLM is the Nous free-tier inference endpoint
|
|
# (https://inference-api.nousresearch.com/v1), model
|
|
# `upstage/solar-pro4:free` (tool-calling, verified reflect). Fallback
|
|
# (documented, NOT deployed): `stepfun/step-3.7-flash:free`. API key via existingSecret
|
|
# envFrom (hindsight-credentials / HINDSIGHT_API_LLM_API_KEY), sourced from
|
|
# 1Password `nous` item per decision 4.
|
|
# - Ingress is driven through the chart's NATIVE ingress template (approved
|
|
# plan: "Ingress driven through values.yaml"). api.service.port=8888,
|
|
# controlPlane.service.port=3000.
|
|
# - Image tag defaults to .Values.version (root) when api.image.tag is unset,
|
|
# so version: "0.9.1" pins the API image to 0.9.1.

|
# LLM section referencing astro-orbiter for years. The nomic-embed-

|
# text-v1.5 model documented across mk-labs skills as "Hindsight's
|
|

#
|
|

|
|
# nomic-embed-text-v1.5 (768 dimensions) crash-looped hindsight-api on
|
|
# rollout: `RuntimeError: Cannot change embedding dimension from 384 to
|
|
# 768: memory_units table contains 1289 rows with embeddings.` The
|
|
# migration path (`ensure_embedding_dimension` in migrations.py) refuses
|
|
# a live dimension change without either re-embedding everything or
|
|
# deleting all existing memory_units rows across every bank (jarvis,
|
|
# hermes, war-machine, and ~18 other agent banks) — a destructive,
|
|
# irreversible operation requiring explicit human approval, not
|
|
# something to do as a side effect of an infra migration task. Reverted
|
|
# immediately; Hindsight keeps its bundled local embedder (384-dim,
|
|
# unchanged, zero data risk) until a deliberate, approved re-embedding

# migration is planned as its own task.

# --- t_d7f8cd65: fix 502s on the serial astro-orbiter node ---
|
|
# astro-orbiter is a single llama-swap process (serial: 1 generate at a
|
|
# time, ctx 64K). Hindsight's default LLM concurrency is 32, so a retain
|
|
# burst hits the node with N parallel calls -> the node rejects/times out
|
|
# the extras -> hindsight-api surfaces APITimeoutError as 502. astro-orbiter
|
|
# is the ONLY LLM endpoint (all ops route there), so cap the whole pool to
|
|
# 1 and pin retain to 1 as well. The upstream chart exposes these as native
|
|
# semaphore config (HINDSIGHT_API_*_MAX_CONCURRENT); no code change needed.
|
|
# Kept at 1 post-cutover: vLLM's single-process-per-model design is also
|
|
# effectively serial for a single generative model instance under this
|
|
# GPU's VRAM budget (KV cache sized tight against the 24GB card at
