Tests cover directory resolution, CLI help, doctor setup, transcript parsing, usage, tools, sub-agents, model fallback, billing modes, and context-curve support.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to edb5c

The new Bahulam transcript integration currently misreports BYOK costs and can produce inconsistent model and token totals; its recursive file discovery can also follow symlinks outside the configured projects directory when a less-trusted process can modify that directory. These are concrete merge-readiness issues, so the PR should not merge until they are fixed or explicitly accepted.

Thanks for this, especially the status/goto, doctor, and cache-provenance integration.

Before I can merge it, could you attach a redacted real ~/.bahulam/projects/**/*.jsonl transcript? Ideally one hosted session and one BYOK session. Prompts, outputs, paths, and identities can be scrubbed, but please preserve event order and the model, usage, cost, credit, and is_byok fields. The current tests are synthetic and therefore repeat the parser's assumptions.

I found two accounting blockers:

  1. _add_usage subtracts cache-read and cache-write tokens from input. Bahulam's per-model input_tokens, cache_read_tokens, and cache_creation_tokens are priced additively, while some flat OpenRouter totals appear inclusive. This likely needs normalization by record shape rather than one formula. The current test locks in the undercount.
  2. Every model row records a cost and also marks all tokens as unpriced. OpenTab's default $ view therefore shows recorded cost + list-price estimate for the same tokens. The split also needs to respect session_info.is_byok versus hosted subscription/credit usage.

A few related items should be addressed after the transcript settles the schema:

  • Mirror Bahulam's $BAHULAM_HOME / $KEPLER_HOME and legacy ~/.kepler resolution.
  • Don't classify unknown bare model IDs as Anthropic.
  • Derive turn cache totals from models[], or disable the Context curve when they are unavailable.
  • Run ruff format; the new test file currently fails the format check.

Since Bahulam already writes Claude-shaped assistant records, would a small Bahulam adapter around the existing Claude parser be simpler than a separate 770-line parser? It would still need Bahulam-specific normalization for billing, cache semantics, and inline events, so I'm suggesting reuse rather than assuming it works unchanged.

Happy to re-review once we have a representative transcript and the accounting behavior is pinned by tests.

Remove the unused helpers and import.

_first_value and _price are never called. Bahulam accounting uses reported costs through _add_usage; it does not use _price. Remove both helpers and the unused api_equivalent_cost import.

Thanks for the detailed review.
I pushed fc6182e with the requested fixes and a few related parser corrections:

  • Removed legacy kepler_event handling from the Bahulam backend. The parser now only accepts current bahulam_event records. Any future users will only see bahulam_event.
  • Normalized accounting by record shape: usage.models[] input/cache fields are additive, while flat aggregate usage remains inclusive.
  • Fixed recorded-cost handling so tokens with reported cost are not also treated as unpriced/list-price estimated.
  • Kept missing-cost usage as unpriced so OpenTab can still estimate where appropriate.
  • Stopped qualifying unknown bare model IDs as Anthropic.
  • Added Bahulam subagent parsing from sub_agent_start / sub_agent_complete, including root vs subagent cost split for both costs and token usage.
  • Updated BAHULAM_PROJECTS_DIR / BAHULAM_HOME resolution and CLI/doctor help text.
  • Ran ruff format --check, ruff check, and focused store/cache tests.

Real local validation against current ~/.bahulam/projects now reports:

sessions: 69
subagents: 7
root_cost: 1.257876
total_cost: 1.486484
subagent_cost: 0.228608

I have attached a redacted hosted transcript preserving event order and the model, usage, cost, credit, and is_byok fields.

bahulam-hosted-latest-redacted-530faf88.jsonl.zip

On the comment that Bahulam already writes Claude-shaped assistant records, an adapter is easy than a separate 770-line parser, but the similarity ends with more functionalities that distinguish the Claude model going forward. It will also help us develop Bahulam/Code independently.

Thanks

Thanks for the update and especially for the real transcript. It answered the central ambiguity, but unfortunately it shows the new model normalization is reversed.

In the attached file, the first completion has:

input_tokens      190101
cache_read_tokens 152448
output_tokens       3341
total_tokens      193442

190101 + 3341 == 193442, so models[].input_tokens already includes cache. The current additive_input=True path reports 345890 for that completion. Across the complete transcript, OpenTab reports 4,717,485 tokens, while the model roles close at 2,554,541: 2,047,863 coder/root plus 506,678 plan subagent.

The hosted billing split is also still open. Every session_info has is_byok:false, and every completion has credits_charged:0, but the parser reports $0.127644 provider cost as recorded user spend. Hosted usage should remain $0/unpriced in normal mode; provider/list cost belongs behind $. BYOK can be treated as metered once verified against a BYOK transcript.

Two smaller blockers:

  • python3 run_tests.py is currently 1187/1188 because test_bahulam_default_dir_honors_current_home_env expects pytest's monkeypatch fixture, which the project's custom runner does not inject.
  • The resolver still omits $KEPLER_HOME and existing ~/.kepler/projects.

Since a Bahulam complete aggregates multiple internal model calls, and sometimes a subagent, it is not a per-request context size. Please also opt this backend out of supports_context_curve unless a true per-request series is used.

The PR currently conflicts with main, so please rebase the branch and resolve those conflicts before the next review.

The unknown-model and subagent parsing changes look like good progress. Once the accounting closes against the supplied transcript, the full suite is green, and the branch is rebased, I'm happy to re-review.

Adds a read-only store for Bahulam session JSONLs under
~/.bahulam/, on par with the Claude and Codex stores.
Supports the full tooling surface: summary, workflows,
model-breakdown, timeline, turn-level detail, tools tab,
demo mode, and cache provenance.
…resolver, custom-runner test

Six specific issues raised by @hamidi-dev:

1. models[].input_tokens is INCLUSIVE of cache_read (not exclusive).
   The previous additive_input=True path double-counted cache reads,
   inflating workflow.total_tokens ~2x. Removed the flag; every code
   path now subtracts cache_read + cache_creation from total_input to
   derive fresh input. Verified against the reviewer's transcript:
   4,717,485 -> 2,554,541 tokens (matches their 2,047,863 coder/root
   + 506,678 plan subagent split exactly).

2. Hosted sessions (is_byok=false) reported provider list cost as
   user spend. Now: track is_byok from session_info + credits_charged
   from complete events; hosted sessions surface credits_charged as
   total_cost and route provider cost into unpriced buckets. BYOK and
   legacy transcripts (no is_byok) keep the previous provider-cost
   behavior. The reviewer's $0.127644 provider figure correctly shows
   as $0 user spend.

3. test_bahulam_default_dir_honors_current_home_env used pytest's
   monkeypatch fixture, which the project's custom run_tests.py does
   not inject (1187/1188 -> 1317/1317). Rewrote with stdlib env
   save/restore.

4. Resolver honors $KEPLER_HOME and falls back to ~/.kepler/projects
   when it exists on disk, smoothing the Kepler-to-Bahulam migration
   for users upgrading in place.

5. Bahulam `complete` events aggregate multiple internal LLM calls
   (plus sub-agent rollups) into one turn row, so tokens_total is not
   a per-request context snapshot. Added supports_context_curve()
   returning False to opt out of context-curve rendering.

6. Rebased onto origin/main; parallel-add conflicts against upstream's
   antigravity + gemini backends resolved by keeping both sides.

Tests: 4 new (hosted-with-$0, hosted-with-charge, byok, context-curve)
and 3 existing updated for corrected math. 1317/1317 passing under
python3 run_tests.py.

Note for reviewers with a pre-fix cache: OpenTab persists parsed
rollups keyed by transcript (path, size, mtime_ns), so a cache written
before this PR will keep serving the double-counted numbers until the
transcript files change. One-time flush:

    opentab tui --source bahulam --no-cache
    # or
    rm -f ~/.cache/opentab/cache/bahulam-*.json

We did not bump CACHE_VERSION because it is shared across every
backend and this is a Bahulam-only correction.

Thanks for the detailed review, @hamidi-dev — every point is addressed in edb5c48, on top of the rebased base.

Important

Before re-testing: flush any pre-fix Bahulam cache. OpenTab persists parsed rollups keyed by transcript (path, size, mtime_ns), so a v11 cache written before this PR will keep serving the old double-counted numbers even with the fix installed. One line:

rm -f ~/.cache/opentab/cache/bahulam-*.json

Or bypass the cache once: opentab tui --source bahulam --no-cache. Without this step you'll see the fix in the code but not in the TUI, which took me a while to notice.

All six blockers, with your transcript as the verification:

Blocker Fix Verified
models[].input_tokens already includes cache; additive_input=True reported 345,890 for the first completion Removed the flag; every path treats input_tokens as inclusive and derives fresh input as input - cache_read - cache_creation. Your transcript: 4,717,485 → 2,554,541 tokens. Role split: 2,047,863 coder/root + 506,678 plan subagent — bit-exact against your numbers.
Hosted is_byok:false + credits_charged:0 reported $0.127644 as user spend Track is_byok from session_info and sum credits_charged from complete events. Hosted sessions: total_cost = sum(credits_charged), provider list cost routes to unpriced. BYOK: unchanged. Legacy transcripts without is_byok: unchanged (backward-compat). Your transcript now shows $0.000000 with tokens in unpriced_tokens.
Custom run_tests.py doesn't inject monkeypatch (1187/1188) Rewrote test_bahulam_default_dir_honors_current_home_env with stdlib env save/restore. 1317/1317 passing. Also added coverage for $KEPLER_HOME and ~/.kepler/projects fallback.
Resolver omitted $KEPLER_HOME and ~/.kepler/projects Added both. Order: $BAHULAM_PROJECTS_DIR$BAHULAM_HOME$KEPLER_HOME~/.bahulam/projects~/.kepler/projects (only if it exists on disk). New tests: test_bahulam_default_dir_falls_back_to_kepler_home_env, ..._legacy_kepler_projects_dir.
A Bahulam complete aggregates multiple internal model calls, so tokens_total isn't a per-request context window Added supports_context_curve() -> False to BahulamStore. New test: test_bahulam_opts_out_of_context_curve.
Branch conflicts with main Rebased onto origin/main; parallel-add conflicts against upstream's antigravity + gemini backends resolved by keeping both sides. Full test suite green after rebase. git log --oneline origin/main..HEAD shows 4 clean commits.

Test additions in edb5c48:

  • test_bahulam_hosted_session_treats_provider_cost_as_unpriced — uses your exact numbers (190101 / 152448 / 3341 / $0.127644) and asserts total_cost == 0, tokens in unpriced.
  • test_bahulam_hosted_session_shows_credits_charged_when_nonzero — paid hosted sessions surface credits_charged as spend.
  • test_bahulam_byok_session_uses_provider_cost — BYOK unaffected by the hosted change.
  • test_bahulam_opts_out_of_context_curve.
  • Three existing tests updated for corrected math (they encoded the bug).

Now the final view looks more accurate and reasonable.

Thanks
Ravi

Four surgical fixes from the follow-up review; two adjacent asks were
verified against current code and skipped with reasons in the PR reply.

1. cli.py --status help text: the previous rebase left two duplicated
   backend groups smashed together with "with DIR only" twice, and
   Antigravity was missing. Replaced with one clean parenthetical
   listing all 11 backends. Test assertion updated to match.

2. doctor: BAHULAM_PROJECTS_DIR, BAHULAM_HOME, and KEPLER_HOME are
   read by the resolver but weren't in _ENV_VARS, so `opentab doctor`
   never reported them even when they were the reason the wrong
   directory was being scanned. Added.

3. cli.py --bahulam-dir help and sources.py no-sessions guidance now
   name every compat env var the resolver actually honors, plus the
   ~/.kepler/projects legacy fallback.

4. bahulam.py total_cost: credits_charged is now added only when
   is_byok is False. Hosted sessions still surface credits_charged as
   user spend; BYOK sessions keep model_cost as the sole source and
   refuse to double-count if a stray non-zero credit slips into a
   BYOK transcript. Also added the missing "filled by
   App._load_model_cache" comment on model_count=0 so it matches
   every other backend.

Not changed (skipped with reason in PR reply):
- model_count=len(model_rows): every other store sets 0 and lets App
  populate from model_breakdown; changing bahulam alone breaks the
  contract.
- "same fix for turn-level tokens": already correct — the turn row
  computes inp = total_in - cr - cw at bahulam.py:570, verified
  against the plugins session (turn TOTAL 92.7M matched model_rows).

Tests: 1317/1317 passing under python3 run_tests.py.

Thanks Ravi. I checked the latest revision against the transcript you attached.
The token accounting is now exact: 2,554,541 tokens total, split into 2,047,863 coder and 506,678 plan. The turn totals close to the same number. The BYOK path is also correct at $0.127644 total**, with the expected **$0.041833 root / $0.085811 subagent split.
That closes the token accounting, path resolution, test isolation, context capability, and rebase issues.
A few blockers remain.

  1. Hosted billing
    credits_charged cannot currently be treated as USD.
    In the supplied transcript, the credit balance changes while credits_charged remains zero for every completion. The balance data also shows that credits are quota units rather than dollars: most calls use roughly 200 credits per USD, while the subagent model has a different conversion rate.
    This causes two problems:
  • Real hosted usage reports $0, despite consuming credits.
  • If credits_charged is nonzero, it is rendered directly as dollars.
    The nonzero branch also double-counts under $: recorded credits are added to total_cost, while the same tokens remain in unpriced_* and receive a second list-price estimate.
    Unless Bahulam exposes a reliable USD field or a documented model-specific conversion, hosted usage should remain token-only: recorded cost $0, tokens unpriced, and $ providing the list-price estimate. BYOK usage can continue using the recorded provider cost.
    records_cost should consequently be determined per store instance, as it is for the other mixed backends, rather than being a class-level True.
  1. Subagent Turns and Tools attribution
    The workflow and node totals are correct, but Turns and Tools assign the subagent usage to the root model.
    Completion 8 contains 343,760 root tokens, while its aggregate includes another 506,678 subagent tokens. The current timeline emits one 850,438-token root-model row, so the subagent tokens and tool usage are attributed to mimo-v2.5 rather than deepseek-v4-pro.
    The child completion needs its own turn rows, tagged with the child agent and model, as the Codex and Gemini stores do.
  2. Usage-less transcripts
    Empty and session_info-only files currently produce phantom workflows. The latter also creates zero-usage model rows for every configured model.
    Sessions and model rows with no recorded usage should be omitted.
  3. Subagent status resolution
    root_of() returns None, so opentab cost task_id-008 prints nothing for a subagent visible in the browser.
    root_of needs to walk the parent chain and return the root session.
  4. BYOK classification timing
    is_byok is currently applied per event. If a completion appears before session_info, that completion is classified as BYOK even when the session is hosted.
    This should be resolved once at session finalization and then applied consistently to every completion in that session.

  • ruff check reports the import-order issue in cli.py.
  • ruff format --check reports stores/bahulam.py and tests/test_stores_bahulam.py.
  • Please add Bahulam to the README backend list/support matrix and document it in docs/sources.md.
    CodeRabbit’s model_count=0 finding can be ignored. Stores initialize it to zero intentionally; App._load_model_cache() fills it from model_breakdown().
    The parser is close now. The core token accounting, BYOK cost path, node tree, resolver, doctor integration, and cache hooks all check out. The remaining substantive work is hosted billing semantics and preserving subagent identity in Turns and Tools.
