What

The Performance tab shows lift as goals met after a conversation ÷ goals met without one. Flipkart asked for the proof behind the "after" half: for each of those customers, which event were they on at our last answered call before the goal. That table was a hand-run Metabase query (25 Sep); this PR puts the same cut on the report itself so the console can show it.

GET /workflows/{id}/report → customers.goal_met_after_by_event:

"goal_met_after_reach": 161,
"goal_met_after_by_event": { "OFFERED": 71, "OFFER_SELECTED": 54, "KYC_COMPLETED": 22, "REPAYMENT_COMPLETED": 14 }

The values always sum to goal_met_after_reach, so the split and the lift are the same set of runs. Loom side: juspay/loom#367.

How

  • get_call_facts_by_runs_query returns two more facts per (run, template), over the same mine set and the same _ANSWERED rule: last_answered_at (latest answered call before the run's exited_at, or so far while open) as a plain max(...) FILTER, and last_answered_event, the stage that call was placed for — COALESCE(payload ->> 'current_stage', payload ->> 'event_name') — picked in its own DISTINCT ON (run, template) CTE, newest call first, and joined back. The facts aggregate stays a HashAggregate and never touches payload; the payload is unpacked once per answered lead. Both words were written when the call square queued the lead (retries carry their parent's), so the word can trail where the customer stood when they answered; that is also why it matches the Metabase definition exactly.
  • build_report folds the dict: each goal counted into goal_met_after_reach adds one under its run's last answered event, the latest across the agents that rang it; (no event) when the payload had none. Busiest first, no-event bucket last.
  • Schema: ReportCustomers.goal_met_after_by_event: Dict[str, int], default empty.

Read path only. No migration, no plan vocabulary change.

Tests

  • Fold: two agents rang one run and the later call wins; a conversation that came after the end is "before" and adds nothing; withdrawn adds nothing; rows sum to after.
  • SQL: "last" is judged by the one answered rule and stops at exited_at; the rule now appears four times in the facts read (answered, first, last, last event).
  • Gates: black / isort / autoflake / pyrefly 0 / boundary guard / 1481 crm tests.

Verified

  • The SQL against real local lead rows returns the event (and NULL → (no event) for a lead pushed without one).
  • Through the route on a seeded local plan (20k runs, 25k calls, 19–26 Sep): every window tried, the by-event rows sum to the after count; rendered on the loom branch.
  • Cost: on a 20,800-run / 25k-lead plan with payloads inflated to 2 KB median (incompressible), three rounds: release 178–346 ms, the ordered-array_agg form 221–260 ms (facts became GroupAggregate + a 3.8 MB sort), this form 223–228 ms with facts back to HashAggregate. Rows identical to the array_agg form on all 14,517 (run, template) pairs. Reader EXPLAIN (ANALYZE, BUFFERS) for 21 Sep and a 7-day window, plus pg_column_size(payload) percentiles, to follow on the thread before merge.
  • To check on prod after release: checkout, 21 Sep full day IST, should give OFFERED 71 / OFFER_SELECTED 54 / KYC_COMPLETED 22 / REPAYMENT_COMPLETED 14 against 161 after — the closed day from the Metabase table.

Not in this PR

A per-event denominator ("spoke on OFFERED and did not convert"), which would turn this into a conversion rate per stage. Add when Flipkart asks which stage to call on rather than which stage converted.

Walkthrough

The report now groups post-reach goals by the event on the latest answered call before a run ends. Call facts include that call’s timestamp and event. Missing event names appear as “(no event),” and the report sorts counts by frequency and event name.

Merge Risk: 🔵 Low · up to b6d2a

The new event breakdown can display buckets in the wrong order or attribute tied calls inconsistently. Both issues are bounded but should be fixed or explicitly accepted before merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to b6d2a

The new breakdown is limited to a merchant’s workflow report and does not show a confirmed access-control bypass. The event labels’ origins and handling by the report client remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The new output exposes aggregate event labels and counts to an authorized workflow-report reader, rather than raw call payloads; the query also filters stamped and retry leads by merchant.

Trust Boundaries and Controls

  • observed — Payload event_name becomes a public report dictionary key. The inspected report path establishes merchant scoping, but not constraints on event-name creation or client-side rendering.

Hardening Proposals

  • proposed — Confirm that event-name producers constrain labels and that report clients render them as text; neither control can be inferred from the report response alone.

Put (no event) last for every count.

If (no event) has more runs than a named event, -kv[1] puts it first. This contradicts the documented ordering. Compare the no-event flag before the count, then sort named events by count and name.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use one deterministic last-call order throughout the report.

Equal call_initiated_time values leave the selected event undefined within a template and across templates. As a result, the same run can enter different event buckets on different reads. Use a stable, unique call identifier to break ties at both selections. PostgreSQL does not define the order of rows with equal sort keys. (postgresql.org)

  • app/database/queries/breeze_buddy/lead_call_tracker.py#L451-L452: order tied calls by a unique identifier and return that identifier with the selected event.
  • app/crm/outreach/analytics.py#L441-L443: use the returned identifier to break timestamp ties across templates.

Based on learnings: “include a stable, unique tie-breaker (such as an id) in the ordering/counting logic.”

Code Review

Found 4 issue(s):

Warning

  • app/database/queries/breeze_buddy/lead_call_tracker.py:L450-452 - The cost is probably underestimated. The description says "same plan shape" and "no new read", but neither holds.

    • Plan shape: the ordered array_agg(... ORDER BY "call_initiated_time" DESC) stops Postgres from using HashAggregate. facts changes from HashAggregate + Hash Left Join to Sort + GroupAggregate + Merge Left Join.

    • New read: payload now goes through that sort for every lead, and is unpacked from storage for every answered one.

    • Local benchmark: PG16, seeded like the description (20.8k runs, ~25k leads):

      payload size added time
      ~170 B +12–20% (matches the +15% in the description)
      ~1.9 KB +26–47%
      ~4.9 KB +24%, plus ~8.5k extra cold buffer reads
    • Why real payloads are likely larger: call-square payloads hold the run facts, the per-square facts_<square>_<key> copies and the rendered playbook blocks. That puts them plausibly at 1.5–4 KB.

    • Why the margin matters: this read runs under the 25 s cancel with windows up to 7 days, and it was one of the reads holding prod on 21 Sep (fix(crm): the console's reads stop scanning the week and stop outliving the browser #1176, a different cause).

    Suggested: before merge, run EXPLAIN (ANALYZE, BUFFERS) on the reader for 21 Sep (full day) and a 7-day window, and check pg_column_size(payload) percentiles for workflow leads. Or keep last_answered_at as the plain max(...) FILTER (...), which keeps HashAggregate, and fetch the event in a separate CTE. This version returned identical rows (EXCEPT ALL empty both ways) at roughly half the added cost when payloads are stored in-line:

    last_ev AS (
        SELECT DISTINCT ON (run_id, COALESCE("template", ''))
               run_id,
               COALESCE("template", '') AS template,
               "payload" ->> 'event_name' AS last_answered_event
        FROM mine
        WHERE {last}
        ORDER BY run_id, COALESCE("template", ''), "call_initiated_time" DESC
    )
    -- ... FROM facts f
    --     LEFT JOIN last_ev e ON e.run_id = f.run_id AND e.template = f.template
  • app/crm/outreach/schemas.py:L893, app/database/queries/breeze_buddy/lead_call_tracker.py:L419, app/crm/outreach/analytics.py:L257 - The docstrings say the event is frozen when the call is dialled, but it is frozen when the lead is queued. They say event_name is frozen "at dial time" / "when it dialled". In fact:

    • The call square builds the payload when it queues the lead as BACKLOG (app/crm/outreach/nodes/call.py:148-152).
    • Retries copy it unchanged (payload=lead.payload at app/ai/voice/agents/breeze_buddy/managers/calls.py:667).
    • A queued lead is not aborted when the run moves on.

    So a customer can move ahead between the queue and the answer: multi-hour morning queues, calling-hours holds, NO_ANSWER/BUSY retries. The answered call then still carries the earlier event, and the goal is counted under it, which pulls the split toward OFFERED. Totals are unaffected and this matches the Metabase definition. But the field measures "the stage the answered call was queued for", not "where the customer was when we spoke". Suggest fixing the three docstrings and the PR description, e.g. "the event_name the call square wrote into the lead's payload when it queued it (retries carry their parent's); may trail where the customer stood when they answered."

  • app/database/queries/breeze_buddy/lead_call_tracker.py:L451 - This reads a merchant-supplied key in the shared outreach report. Nothing in app/crm writes payload ->> 'event_name'; it only arrives through the merchant's inbound letter or catalog fields.

    • Other plans get no split: for any plan whose letters don't carry event_name (the Shopify cart/COD plans, docs/crm/plans/loan-dropoff.json), the whole split collapses to {"(no event)": N}.
    • A CRM-owned alternative exists: current_stage is owned by the walker. run_facts stamps it for every call square that has a stage label (app/crm/outreach/nodes/context.py:199-200), and retries already carry it. Reading it first gives ladder plans a real split. Flipkart's result is unchanged, since nudge-call has no stage label and falls through to event_name:
    COALESCE("payload" ->> 'current_stage', "payload" ->> 'event_name')

    At minimum, document that the split is only meaningful for plans whose letters carry an event_name fact.

  • app/crm/outreach/analytics.py:L358-363 - (minor) The sort only puts (no event) last when counts tie. The key (-count, is_no_event, name) sorts {"(no event)": 5, "OFFERED": 2} with (no event) first. That contradicts the inline comment and the description ("the no-event bucket last"), and it's exactly the shape every plan without event_name returns. Either reword the comment (no-event last only among ties) or change the key:

    key=lambda kv: (kv[0] == _NO_EVENT, -kv[1], kv[0]),

Checked and fine:

  • The split sums to goal_met_after_reach. Python's first < ending.exited_at and the SQL < COALESCE(exited_at, now()) are both strict comparisons on timestamptz, and the call that sets first also passes last.
  • No SQL injection. last only inserts the _ANSWERED constant.
  • Tests: both new tests pass when walked through by hand.
  • Repo rules: CLAUDE.md, AGENTS.md and docs/crm/building-modules.md are followed, and the boundary check passes.
  • Tie-break: a tie on equal call_initiated_time is possible in theory, but it cannot change any count.

Suggestion: make goal_met_after_by_event work for every plan

Following up on point 3 of the review above. The split should not depend on a key the merchant happens to send. payload ->> 'event_name' only exists when the merchant's letters carry it. For every other plan (Shopify cart/COD, docs/crm/plans/loan-dropoff.json, any future merchant), the whole split collapses to {"(no event)": N}. The shared outreach report should be built from the CRM's own concepts.

The CRM already knows where the customer was

A letter's topic is the CRM's own name for an event. Every run already records the letters it heard, on its own trail:

  • Founding letter: context.source_event_id, stamped when the run enters.
  • Every later letter: crm_workflow_step.cut_short_by (canon T26), for each letter that interrupted one of its squares.

The run timeline already names these through record's event_topics. So:

Where the customer was when we last spoke = the topic of the latest producer letter the run had received (received_at) before its last answered call began.

What this fixes beyond making it merchant-independent

Review point Before With this change
3 · merchant-specific key reads payload->>'event_name'; other plans get one (no event) bucket reads letter topics; every plan gets a real split with no plan changes. Flipkart's split is the same, labelled LINE_OFFERED, LINE_KYC_COMPLETED, …
2 · stale event the event saved when the call was queued (and copied onto retries) judged when the call was answered: a customer who moved on while the call sat in the queue is counted where they stood when we spoke
1 · perf ordered array_agg over payload forced Sort + GroupAggregate and read every answered lead's payload the facts read keeps only max(...) FILTER, so it is a HashAggregate again and never touches payload
4 · sort (no event) last only on ties always last: key (kv[0] == _NO_EVENT, -kv[1], kv[0])
tie-break (CodeRabbit) order of equal timestamps is undefined in both SQL and Python picked in the pure fold; equal received_at breaks by topic, so re-reading gives the same result

Our own call reports (CALL_REPORT_SOURCES) are left out. This is the same rule as _reply_patch's latest_letter: they say what we did, not where the customer stands.

Shape (layer and boundary rules kept)

  • Lead store (get_call_facts_by_runs_query): returns last_answered_at only. last_answered_event and the payload read are removed.
  • Outreach (db/queries/step.py → letters_heard_query): (run_id, letter_id) pointers.
    • Covers only the runs that met their goal after a conversation, not every run in the window.
    • Founding letters come from the run row; later letters come from crm_workflow_step via crm_workflow_step_run_ix. Both are tenant-first.
  • Record (new contract producer_letters, returning HeardLetter{topic, received_at}): a primary-key read of crm_event_raw, with source <> ALL(CALL_REPORT_SOURCES). Outreach never reads record's table (rule 12).
  • build_report(endings, facts, letters=None) stays pure: _heard_when_we_last_spoke picks the latest letter received before the last answered call.
  • _spoken_goals chooses which runs to read. It uses the same condition that makes build_report count a goal as "after", so the rows always sum to goal_met_after_reach.
  • Loom: the field name and shape are unchanged, so juspay/loom#367 keeps working. It will now receive topic names (LINE_*), so check how it labels them.

Verified

  • black, isort, autoflake, pyrefly check: 0 errors; check_crm_boundaries.py: clean.
  • tests/crm: 1487 passed.
  • 6 new or reworked tests:
    • the split by letter topic;
    • judged when the call was answered, not queued;
    • no-event bucket last;
    • the facts read never touches the payload;
    • both SQL builders;
    • only the goal runs we spoke to before they ended are read, and call reports are skipped.
  • End to end on Postgres 16 with all 79 migrations applied, through the real accessors:
    • facts plan is back to HashAggregate;
    • Flipkart-style run → LINE_OFFER_SELECTED, even though the lead's payload still said OFFERED (the customer selected an offer while the call was queued), ignoring our call report, another merchant's letter and a letter received after the call;
    • Shopify-style run with no event_name anywhere → checkouts/create;
    • run with no founding letter → (no event);
    • only the goal runs we spoke to before they ended were read.

Prod check after release: the 21 Sep numbers (71 / 54 / 22 / 14) should come back under the LINE_* names. Where they differ, the difference should be runs whose customer moved on while the call was queued; those now count under the later stage, which is the intended behaviour.

Known limit: a step records one cut_short_by. If two letters wake the same open square before it closes, only the second is kept on the trail. This is rare, and the kept one is the later letter anyway.

Thanks for the deep pass. Taking points 1, 2 and 4 as they stand, and half of 3. Not taking the letter-topic proposal, because it answers a different question from the one this column is for.

What the column is for

Flipkart's ask, and the Metabase table already sent to them, is: for which event did we call the customer, after which they converted. The unit is the call we placed. A call is queued for an event: the call square copies that event's facts into the lead, the agent speaks from that event's script, and the lead carries that word for its whole life. The column reads the word off the last answered call before the goal, so it says which call, placed for which reason, preceded the conversion.

The letter-topic version answers: what was the last event the customer was on before the goal, regardless of whether we called about it. Take the example from the suggestion. The OFFERED call is queued at 09:00, OFFER_SELECTED arrives at 09:20, the OFFERED call is answered at 10:30, the customer converts. The proposal credits OFFER_SELECTED, an event we may or may not have called about (the plan does re-enter on it, but that second call is its own lead with its own word, and it may never have been answered). This column credits OFFERED, the call that was actually made and answered. Both are legitimate cuts, but only the second one is "the event we called for", and swapping the definition would silently change the numbers Flipkart already has.

So the semantics stays: the event the call was queued for. Point 2 is right that "dial time" was the wrong phrase for it; the docstrings and the description will say queued, and note that retries carry their parent's word. That is also why it matches the Metabase definition exactly.

What changes

  • Cost (1): agreed. The ordered array_agg goes; last_answered_at stays a plain max(...) FILTER so the facts read keeps HashAggregate, and the event comes from your DISTINCT ON CTE joined on (run_id, template), so payload is unpacked once per answered lead and never sorted. Will post EXPLAIN (ANALYZE, BUFFERS) from the reader for 21 Sep and a 7-day window, plus the pg_column_size(payload) percentiles for workflow leads, before merge.
  • Wording (2): agreed, as above. Three docstrings and the PR body.
  • Merchant key (3): taken in part. The read becomes COALESCE(payload ->> 'current_stage', payload ->> 'event_name'), so a ladder plan with stage labels gets a real split with no plan change; Flipkart is unchanged since nudge-call has no stage. Plans with neither get the single (no event) bucket, documented on ReportCustomers and on the loom side, which already hides the block in that case.
  • Sort (4): agreed, key becomes (kv[0] == _NO_EVENT, -kv[1], kv[0]), no-event bucket always last.

The letter-topic cut is worth having as its own field later, "where the customer stood when we spoke", next to this one rather than instead of it. Happy to take that as a follow-up once this lands.

…goal

The Performance tab shows lift as goals met after a conversation over goals
met without one. Flipkart asked for the proof behind the "after" half: for
each of those customers, which event did we call them for, after which the
goal letter arrived. Until now that table was a hand-run Metabase query
(25 Sep 2026); this puts the same cut on the report itself.

- get_call_facts_by_runs_query returns two more facts per (run, template):
  last_answered_at, the latest answered call before the run's exited_at (or
  so far, while open), as a plain max(...) FILTER beside first_answered_at;
  and last_answered_event, the stage that call was placed for — the call
  square's stage label (current_stage) when it has one, else the event_name
  fact — picked in its own DISTINCT ON CTE (newest call first, id as the
  tie-break) and joined back, so the facts aggregate stays a hash aggregate
  and never sorts or unpacks `payload`; the payload is read once per
  answered lead. Both words were written into the payload when the call
  square QUEUED the lead, and a retry carries its parent's, so the word can
  trail where the customer stood by the time they answered.
- build_report folds `goal_met_after_by_event` on ReportCustomers: every goal
  counted into goal_met_after_reach adds one under its run's last answered
  event, the latest across the agents that rang it; "(no event)" when the
  payload carries neither a stage label nor an event_name. Busiest first,
  the no-event bucket always last. Its values always sum to
  goal_met_after_reach, so the split and the lift are the same set of runs.
  Plans without stage labels or event_name facts get the single "(no event)"
  row; the console hides the block in that case.
- Tests: the fold (two agents, the later call wins; a conversation after the
  end counts as before; withdrawn adds nothing; no-event last even when it is
  the biggest bucket), the SQL (last is judged by the one answered rule and
  stops at exited_at; no array_agg; facts never reads payload; the DISTINCT
  ON CTE and its join), and the two rule-count assertions.

Verified locally against real lead rows and through GET /workflows/{id}/report
on a seeded plan: the by-event rows sum to the after count on every window
tried; a stage-labelled call lands under its label. On 20,800 runs with 2 KB
payloads the read costs the same as the release version and returns rows
identical to the ordered-array_agg form it replaces.
