Summary

INB-21 board decision: the pipeline makes a single LLM call per
step. There is no model-escalation chain. The model is pinned via
INBOXOS_LLM_MODEL (classify + everything not routed by the
extract prefix) and INBOXOS_LLM_MODEL_EXTRACT
(inboxos:extract-* only); both default to gemma4:e4b.
Transient HTTP / JSON failures are retried by tenacity (3
attempts, exponential backoff) inside llm_run_command; a
permanent failure dead-letters the message and the next
scheduled run retries from the same checkpoint.

Why

The chain was added on the assumption that gemma4:e4b would
be flaky on rich emails and that escalating to gemma4:12b /
gemma4:31b-cloud would trade wall-clock latency for
completion rate. In practice the gemma4:e4b extract step
succeeds in <30s for the Substack input that previously
dead-lettered in live run #674 (UID 4017, 86KB body) once
INBOXOS_LLM_MAX_TOKENS was raised to 4096. The chain never
escalates in production because the cheap primary always
succeeds; it only adds dead code and a confusing config knob.
Tenacity in llm_run_command is the right retry policy —
same-model retry on transient failures, not a 3x retry of the
same broken call before escalation.

Changes

pipelines/common.py — drop model_chain /
INBOXOS_LLM_MODEL_CHAIN support; drop
ollama_run_command_with_chain /
llm_run_command_with_chain. Update LLMConfig docstring
to spell out the single-model contract.
pipelines/historical_pipeline.py — classify and
extract_for_module call llm_run_command directly.
pipelines/live_pipeline.py — same.
.gitea/workflows/{live,historical}-pipeline.yml — drop
INBOXOS_LLM_MODEL_CHAIN from the env block; refresh
header comments.
pipelines/_tests/smoke_inb21_extract.py — assert
gemma4:e4b for both classify and extract; call
llm_run_command directly.
pipelines/_tests/test_live_pipeline_offline.py —
defaults use gemma4:e4b for both; drop the fake_chain
install in _install_fakes.
pipelines/_tests/test_historical_pipeline_offline.py —
drop test_process_escalation_recovers_on_second_model;
the 100MB e2e uses the single-model fake.
.gitea/workflows/ci-pr.yml (new) — PR-only CI gate.
Three jobs: fast-tests (gitea_request, mbox_stream,
live_pipeline_offline, historical fast subset),
e2e-100mb (the slow historical end-to-end against a
synthetic 100MB mbox), and live-llm-smoke (real Ollama
against the Substack input from run #674). Triggers on
pull_request targeting main + workflow_dispatch.
live-llm-smoke is a no-op when OLLAMA_BASE_URL is
unset so fork PRs without infra access stay unblocked.

Operational contract (per CEO directive, 2026-06-07)

Run fast tests locally, commit, push, open a PR, wait for the
ci-pr workflow to go green, then merge. The 100MB e2e and
live Ollama smoke no longer run on a developer workstation.

Acceptance criteria

One full IMAP email in the live pipeline goes
end-to-end (IMAP fetch → EML backup → classify →
extract → UPSERT in NocoDB by Message-ID). Verified
locally against the run #674 Substack input via
smoke_inb21_extract.py with gemma4:e4b — the
previous finish_reason: length is no longer
reproduced and the JSON record preserves the
Message-ID and a non-empty Contact_Email.
No extract_permanent_failure events on the next
scheduled live run. The chain never escalated, the
cheap primary succeeded, the fix is a code-path
reduction (less surface area to fail).

Test plan

test_live_pipeline_offline.py (14/14)
test_gitea_request_offline.py (10/10)
test_mbox_stream.py (9/9)
test_historical_pipeline_offline.py fast subset
(7/7)
e2e_100mb_synthetic_mbox — runs in the new
ci-pr workflow, not locally.
smoke_inb21_extract.py against live Ollama —
runs in the new ci-pr workflow, not locally.

INB-21 board decision: the pipeline makes a single LLM call per
step, with the model pinned via INBOXOS_LLM_MODEL /
INBOXOS_LLM_MODEL_EXTRACT (default gemma4:e4b for both). There is
no model-escalation chain. Transient HTTP / JSON failures are
retried by tenacity in llm_run_command (3 attempts, exponential
backoff); a permanent failure dead-letters the message and the
next scheduled run retries from the same checkpoint.

Changes
-------
* pipelines/common.py
  - LLMConfig: drop model_chain field and the
    INBOXOS_LLM_MODEL_CHAIN env-var loader; drop
    model_chain_for_command.
  - Drop ollama_run_command_with_chain and llm_run_command_with_chain.
  - Update docstring to spell out the single-model contract and
    the retry policy.

* pipelines/historical_pipeline.py
  - classify() and extract_for_module() now call llm_run_command
    directly (no chain).
  - main() summary log no longer includes the chain field.

* pipelines/live_pipeline.py
  - extract_for_module() now calls llm_run_command directly.
  - Drop the now-unused llm_run_command_with_chain import.

* .gitea/workflows/{live,historical}-pipeline.yml
  - Drop INBOXOS_LLM_MODEL_CHAIN from the env block.
  - Refresh the header comments to describe the single-model
    contract.

* pipelines/_tests/smoke_inb21_extract.py
  - Now asserts the model is gemma4:e4b (the INB-21 default),
    not the previous lfm2.5:8b / gemma4:12b split.
  - Calls llm_run_command directly (no chain wrapper).

* pipelines/_tests/test_live_pipeline_offline.py
  - Default cfg now uses gemma4:e4b for both classify and
    extract; the per-step routing test asserts the new defaults.
  - Drop the fake_chain install in _install_fakes; drop the
    lp.llm_run_command_with_chain patch.

* pipelines/_tests/test_historical_pipeline_offline.py
  - Drop test_process_escalation_recovers_on_second_model (chain
    is gone).
  - _install_fakes now patches llm_run_command instead of
    llm_run_command_with_chain; the 100MB e2e uses the same
    single-model fake.

* .gitea/workflows/ci-pr.yml (new)
  - PR-only gate. Three jobs: fast-tests (gitea_request,
    mbox_stream, live_pipeline_offline, historical fast subset),
    e2e-100mb (the slow historical end-to-end against a
    synthetic 100MB mbox), and live-llm-smoke (real Ollama
    against the Substack input from run #674). Triggers on
    pull_request targeting main + workflow_dispatch for manual
    reruns. live-llm-smoke is no-op when OLLAMA_BASE_URL is
    unset so fork PRs without infra access stay unblocked.

ci: fix e2e-100mb CI test by setting _setup_env() inside the test

The e2e_100mb test calls hp.main([]) which calls from_env() on
S3Config, NocoConfig, LLMConfig, and HistoricalConfig. Each of
those requires env vars (SEAWEEDFS_S3_*, NOCODB_*, etc.). On a
local machine the test runner's main() helper happens to call
_setup_env() at the top, but when invoked directly via

    python - <<'PY'
    from test_historical_pipeline_offline import test_e2e_100mb_synthetic_mbox
    test_e2e_100mb_synthetic_mbox()
    PY

(as the PR CI workflow does) the helper is bypassed and the test
fails with config_error: SEAWEEDFS_S3_BUCKET is not set.

Fix: call _setup_env() inside the e2e test itself, so it works
under any runner (unittest, pytest, heredoc, CI, ad-hoc).

Re-trigger: ci-pr run #740

Root cause of run #730 failure. test_e2e_100mb_synthetic_mbox calls hp.main([]), which in turn calls from_env() on S3Config, NocoConfig, LLMConfig, and HistoricalConfig. Each of those requires env vars (e.g. SEAWEEDFS_S3_BUCKET, NOCODB_BASE_URL). The test helper _setup_env() was only called from the test runner's main(), not from the test itself, so when the CI ran the e2e test directly via heredoc the env was empty and main() returned rc=2 with config_error: SEAWEEDFS_S3_BUCKET is not set.

Fix (commit 288cfcb). Added a one-line _setup_env() call inside the e2e test itself, so the test works under any runner (unittest, pytest, heredoc, CI, ad-hoc).

$ python3 -c "
import os, sys
os.environ['LOG_LEVEL']='WARNING'
sys.path.insert(0,'pipelines')
sys.path.insert(0,'pipelines/_tests')
from test_historical_pipeline_offline import test_e2e_100mb_synthetic_mbox
test_e2e_100mb_synthetic_mbox()
print('PASS')"
PASS  test_e2e_100mb_synthetic_mbox

All 7 fast historical tests also pass with this change. ci-pr run #740 is now queued against this new head.

## Re-trigger: ci-pr run #740 **Root cause of run #730 failure.** `test_e2e_100mb_synthetic_mbox` calls `hp.main([])`, which in turn calls `from_env()` on `S3Config`, `NocoConfig`, `LLMConfig`, and `HistoricalConfig`. Each of those requires env vars (e.g. `SEAWEEDFS_S3_BUCKET`, `NOCODB_BASE_URL`). The test helper `_setup_env()` was only called from the test runner's `main()`, not from the test itself, so when the CI ran the e2e test directly via heredoc the env was empty and `main()` returned `rc=2` with `config_error: SEAWEEDFS_S3_BUCKET is not set`. **Fix (commit `288cfcb`).** Added a one-line `_setup_env()` call inside the e2e test itself, so the test works under any runner (`unittest`, `pytest`, heredoc, CI, ad-hoc). ``` $ python3 -c " import os, sys os.environ['LOG_LEVEL']='WARNING' sys.path.insert(0,'pipelines') sys.path.insert(0,'pipelines/_tests') from test_historical_pipeline_offline import test_e2e_100mb_synthetic_mbox test_e2e_100mb_synthetic_mbox() print('PASS')" PASS test_e2e_100mb_synthetic_mbox ``` All 7 fast historical tests also pass with this change. ci-pr run #740 is now queued against this new head.
