+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Base namespace predicates generate unnecessary prefixes in Turtle/LongTurtle output
+
+## Description
+When serializing data into Turtle or LongTurtle formats, predicates that belong to the base namespace are incorrectly rendered with an explicit prefix. For example, a predicate that should appear as `myPredicate` might instead be output as `base:myPredicate` or `_base:myPredicate`. This is unexpected, as predicates in the base namespace should not require an explicit prefix.
+
+Additionally, in LongTurtle format, pnames (prefixed names) containing bracket characters are not properly escaped, leading to malformed output.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `1964642d472c` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Internal ConjunctiveGraph warning displayed when processing JSON-LD
+
+## Description
+When processing JSON-LD data, an internal `ConjunctiveGraph` warning is unexpectedly displayed in the console or logs. This warning indicates the use of a deprecated component within the library. The expected behavior is that no such warning should appear, ensuring clean output and indicating up-to-date internal component usage.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `b459049af00b` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Turtle/N3 serializers output undeclared prefixes for predicates matching the base URI
+
+## Description
+When serializing an RDF graph to Turtle, Long Turtle, or N3 format, if a base URI is set and a predicate URI contains that base URI as a substring (e.g., the predicate starts with the base URI), the serializer incorrectly outputs an undeclared prefix for that predicate.
+
+For example, if the base URI is `http://example.org/base/` and a predicate is `http://example.org/base/something`, the output might contain `base:something` without `base` being declared as a prefix. This results in invalid Turtle/N3 output.
+
+The expected behavior
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `2a902e512123` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+    they block `command_resolved` and are recorded for transparency.

+# Issue
+
+**Title:** Incorrect "changed size" reported or unstable iteration when processing store graphs
+
+## Description
+When iterating through the graphs within the store, the "changed size" metric is not being updated or reported accurately. Additionally, the iteration process itself appears unstable, potentially leading to inconsistent results or missed items. Expected behavior is that iterating over the store's graphs should reliably and accurately reflect the "changed size" and provide a stable, consistent traversal of all graphs.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `9b14b8f97994` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** WGS namespace IRI mismatch leads to incorrect Turtle serialization prefixes
+
+## Description
+When serializing data containing WGS (W3C Basic Geo) vocabulary to Turtle, the system currently uses an `https://` namespace IRI. This `https://` IRI does not align with the standard `http://www.w3.org/2003/01/geo/wgs84_pos#` IRI found in published W3C data. As a result, the Turtle serialization invents an incorrect `wgs1:` prefix for the WGS vocabulary. The expected behavior is for the system to use the official `http://` WGS namespace IRI, allowing for correct and consistent prefixes like `geo:` or `wgs:` in Turtle output.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `695f864a6763` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Invalid QName generated for XML namespace URIs
+
+## Description
+When a URI starts with `http://www.w3.org/XML/1998/namespace/` (including a trailing slash), it is incorrectly serialized.
+
+**Expected behavior:** The URI should be serialized as a valid QName or a full IRI, allowing it to be parsed back successfully.
+**Actual behavior:** The URI is serialized as `xml:/`, which is not a valid QName and causes subsequent parsing to fail.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `5abda95ac70c` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Turtle/LongTurtle serializer corrupts shared RDF lists with shared internal cells
+
+## Description
+When serializing an RDF graph using the Turtle or LongTurtle format, if an RDF list contains an internal cell (not just the head of the list) that is referenced by multiple subjects, the serializer incorrectly uses the compact `(...)` collection syntax. This causes the shared list cell to be consumed by one reference, leaving other references to that cell undefined in the serialized output. The resulting serialization is incomplete and does not round-trip, leading to data loss.
+
+**Reproduction:**
+Given the following RDF graph:
+```turtle
+_:tail rdf:first "
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `29eb45e55fd6` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+

+# Issue
+
+**Title:** Incorrect Deskolemization of Literals
+
+## Description
+When processing logical expressions containing literals, the deskolemization step produces incorrect results. This leads to an inaccurate representation or evaluation of the original expression. The expected behavior is that literals should be deskolemized correctly, maintaining the logical equivalence of the expression.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `747b8d30e6ca` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** `Dataset.add()` method has poor performance
+
+## Description
+The `Dataset.add()` method exhibits significant performance degradation, particularly when adding multiple triples or graphs. This leads to unacceptably long execution times for operations involving frequent additions to a `Dataset`. The expected behavior is for `Dataset.add()` to be performant and efficient, even when handling a large number of additions.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `507a4e1d1a35` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Corpus extractions produce invalid data
+
+## Description
+When performing corpus extractions, the system generates data that is incorrect or malformed. This issue leads to unreliable or unusable output, hindering subsequent data processing or analysis steps.
+
+**Expected behavior:** Corpus extractions should consistently produce valid and correctly structured data.
+**Actual behavior:** Corpus extractions yield invalid results.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `077d0fff5014` and running the modified tests.

+ ## Results
+ 
+-- Runtime path: deterministic whole-string parse, extraction-first for noisy text, LALR fallback only on misses. Earley is not used at runtime.
+-- Test suite: `127 passed in 0.22s`
+-- Tight loop: `19.52 us/input` at `10000` rounds
+-- Internal path benchmark:
+-  - `fast exact`: `6.5 us`
+-  - `fast collection`: `19.5 us`
+-  - `extract hit`: `46.1 us`
+-  - `extract miss`: `13.6 us`
+-- Cross-library snapshot from `benchmarks/benchmark_baselines.py`:
+-  - `timefhuman`: `56.1 us/input`, `37/37 ok`, `10/10 exact`
+-  - `parsedatetime`: `45.0 us/input`, `36/37 ok`, `6/10 exact`
+-  - `datefinder`: `42.9 us/input`, `23/37 ok`, `5/10 exact`
+-  - `recurrent`: `195.2 us/input`, `36/37 ok`, `6/10 exact`

+-  - `dateparser`: `49105.3 us/input`, `20/37 ok`, `6/10 exact`
++- Runtime path: deterministic whole-string parse first, bounded extraction for noisy text, LALR fallback only on misses. Earley is not used at runtime.
++- Correctness: public `timefhuman(...)` now completes on the `datefinder` `core_corpus` and `seattle_html_76k` datasets without raising conversion errors.
++- Test suite: `137 passed in 0.55s`
++- Warm whole-document median on this machine:
++  - `core_corpus`: `timefhuman 0.00199s` for `10` matches, `datefinder.extract 0.00045s` for `14` matches
++  - `seattle_html_76k`: `timefhuman 0.09717s` for `48` matches, `datefinder.extract 0.07821s` for `57` matches

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Timezone information is not handled when a specific time is not provided
+
+## Description
+When attempting to use or apply timezone information without explicitly specifying a time component (e.g., providing only a date or a timezone object), the system fails to correctly process the timezone. The expected behavior is that timezone information should be correctly handled, potentially defaulting to a time like midnight, or at least not causing incorrect behavior or errors due to the absence of a specified time.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `6dec2fbf6fce` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Grammar incorrectly matches subsets of words
+
+## Description
+The current grammar rules are too broad, leading to unintended matches. When a specific word or phrase is defined, the grammar sometimes incorrectly matches a shorter subset of that word or phrase. This results in inaccurate parsing and recognition. The expected behavior is for the grammar to only match complete, distinct words or phrases as defined, without matching their partial components unless those components are explicitly defined as standalone terms.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `3d9f5f1ba0ea` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** `now` value is static and doesn't update after program start
+
+## Description
+The `now` function or variable provides a timestamp that is populated only once when the program initializes. Consequently, any subsequent calls to retrieve the current time will return the initial startup time, rather than the actual current time.
+
+**Expected behavior:** Each time `now` is accessed, it should return the current system time.
+**Actual behavior:** `now` returns a fixed timestamp corresponding to the program's start time, regardless of how much time has passed.
+
+**Reproduction:**
+1. Start the program.
+2. Log or display the `now` value.
+3. Wait for a few seconds.
+4. Log or display the `now` value again.
+5. Observe that both logged values are identical, even though real time has progressed.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `a5bd07e78928` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** `set_args` fails to interpret dot notation for nested arguments
+
+## Description
+When attempting to set arguments for nested configurations using dot notation with `set_args`, the values are not correctly applied to the intended nested paths. Instead, the system either creates a flat key using the full dot-separated string or fails to set the value at all. The expected behavior is for `set_args` to correctly parse the dot notation and set the value at the corresponding nested path within the configuration.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `7a60ee1d0e8c` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Sequence validator raises AttributeError when validating a mapping
+
+## Description
+When a field is typed as `Sequence[T]` and a mapping (e.g., a dictionary) is provided as input for that field, the validation process incorrectly raises an `AttributeError`. The expected behavior is for the validator to either successfully validate the mapping if it conforms to a sequence, or to raise a more appropriate validation error indicating a type mismatch, rather than an `AttributeError`.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `200203f9c4a5` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Filename defaults and relative paths behave unexpectedly
+
+## Description
+Currently, `Filename.default` values are strictly validated as if they were final filenames, preventing the use of template-like default values. This restricts the flexibility of defining default filename patterns. Additionally, it's not possible to define a `Filename` that is relative to another `Filename` if the parent `Filename` is only defined via a default value and not explicitly present in the configuration.
+
+The expected behavior is for `Filename.default` to accept any template-like string, and for relative `Filename` definitions to correctly resolve against parent `Filename`s that have default values, even if those parents are not explicitly configured.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `72eb9a44f398` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Application does not load configuration from XDG_CONFIG_DIRS
+
+## Description
+The application fails to discover and load configuration files located in directories specified by the `XDG_CONFIG_DIRS` environment variable.
+
+**Reproduction:**
+1. Set `XDG_CONFIG_DIRS` to a path like `/etc/xdg:/usr/local/etc/xdg`.
+2. Place a relevant configuration file (e.g., `myapp.conf`) in `/etc/xdg/myapp.conf`.
+3. Run the application.
+
+**Expected behavior:**
+The application should load `myapp.conf` from `/etc/xdg/myapp.conf`.
+
+**Actual behavior:**
+The application does not find or apply the configuration from `/etc/xdg/myapp.conf`.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `d4ab55771649` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** "Payment not received" failed-SIP rows are not classified as REVERSAL
+
+## Description
+When processing SIP rows, entries that have both the status "Payment not received" and are marked as "failed-SIP" are not being correctly classified. Currently, these specific rows are not categorized as `REVERSAL`. The expected behavior is for all rows matching these criteria to be classified as `REVERSAL`.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `220edcfd7a16` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+When processing PDF documents using `read_cas_pdf`, `pypdfium` reports "objects still open" warnings during application teardown, indicating that PDF documents are not being properly closed after use. PDF documents should be closed to prevent resource leaks and avoid these warnings.
+
+Additionally, when parsing CDSL Mutual Fund holdings, folio numbers that span across columns (e.g., "910121125" in one column and "82/0" in an adjacent column) are incorrectly parsed. The "82/0" portion is currently misinterpreted as a separate "mode" column, leading to the truncation of the actual folio number. The full folio number, such as "91012112582/0", should be correctly assembled and parsed as a single entity.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `789865de12b2` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** STP is not classified as a switch across RTAs
+
+## Description
+When STP (Spanning Tree Protocol) is present, the system fails to classify it as a switch. This misclassification occurs consistently across both RTAs.
+Expected behavior: STP should be correctly identified and classified as a switch.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `8dcabe8aeec4` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** JSON export fails with PydanticSerializationUnexpectedValue for reclassified transactions
+
+## Description
+When transactions are reclassified, the `TransactionType` field incorrectly stores a string representation of the enum rather than the enum object itself. This leads to a `PydanticSerializationUnexpectedValue` error when attempting to export data to JSON, particularly for merged descriptions. The expected behavior is for the `TransactionType` field to consistently hold the correct enum value, allowing JSON export to complete successfully without errors after reclassification.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `96ce8cdb5561` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** CDSL CAS: Mutual Fund holdings show incorrect (zero) current value for certain row formats
+
+## Description
+When parsing CDSL Consolidated Account Statements (CAS), some Mutual Fund holdings rows are incorrectly processed, leading to a reported current value of zero. This happens for a specific row variant where a distribution mode column (e.g., ARN/DIRECT) is present, but there is no separate "invested / total cost" column. In these cases, the row contains only three numeric columns: units, NAV, and current value.
+
+**Actual Behavior:** The current value for such holdings is parsed as 0, which also results in an incorrect (lower) total balance for the MF-Folios.
+**Expected Behavior:** The current value should be correctly extracted from the third numeric column in these specific rows, and the total MF-Folios balance should accurately reflect the sum of all holdings' current values.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `226c7d016abe` and running the modified tests.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Incorrect Mutual Fund Profit/Return Calculation
+
+## Description
+When calculating the profit or return for Mutual Funds, the reported figures are inaccurate. The system currently calculates these values based on the position, which leads to incorrect financial outcomes. The expected behavior is for Mutual Fund profit/return to be accurately determined using the value-cost identity.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `ea95d2eee7e1` and running the modified tests.

+ # Changelog
+ 
++## 1.2.x
++
++### New
++
++- `NSDLCASData.parse_warnings` — non-fatal warnings for demat holdings whose
++  numbers don't reconcile.
++
++### Fixed
++
++- NSDL demat holdings parsed by arithmetic (`units*nav≈value`) instead of
++  hardcoded pixel columns; fixes wrong nav/value on layout-shifted statements.
++- NSDL equities: same fix (`shares*price≈value`) + pledged sub-rows no longer
++  parsed as separate holdings.
++- CDSL mutual-fund profit/return assigned by `value-cost` identity, not
++  position; fixes return% being reported as profit.
++
++### Changed
++
++- `CapitalGainsReport` is lazy-loaded, keeping `import casparser` lighter.
++
+ ## 1.2.1
+ 
+ ### Fixed

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** Stamp duty over-allocated when a purchase lot is sold in multiple parts
+
+## Description
+When a single purchase lot is partially sold across multiple disposals, the stamp duty allocated to each subsequent partial sale is incorrectly calculated. This leads to an over-allocation of the total stamp duty, exceeding

++- **Stamp-duty allocation on split lots.** When a single purchase
++  lot is consumed across N disposals the `FIFOUnits.sell` re-queue
++  carried the *full* original stamp duty on every remaining slice,
++  so the proportional allocation re-claimed the same paid stamp
++  on each disposal — total stamp claimed grew unboundedly with
++  split depth. (Worked example: 300-unit lot with ₹1.25 stamp,
++  split 100/100/100 → total claimed ₹2.29 vs ₹1.25 paid, an 84%
++  over-claim that further widens for deeper splits.) The lot is
++  now re-queued with the *unallocated remainder* (`purchase_tax -
++  stamp_duty`), so the invariant `Σ(stamp_claimed) == stamp_paid`
++  holds exactly across any number of partial consumptions. Section
++  48 only permits deducting the stamp actually paid as a
++  transfer expense, so the prior behaviour over-stated the
++  deduction on Schedule 112A.

+"""In-container verifier for pr_runtime tasks (graded F2P/P2P reward).
+
+This module is the **standalone verifier** that runs inside the task's
+Docker container, NOT a helper used at generation time. It is read as
+source at generation time, base64-encoded, and embedded into
+``tests/test.sh``. At run time the container decodes it back to a file
+and invokes it after the test suite has run.
+
+Why a graded reward instead of binary pass/fail
+------------------------------------------------
+SWE-bench resolution is binary: a patch "resolves" the issue iff ALL
+FAIL_TO_PASS tests pass AND ALL PASS_TO_PASS tests still pass. That's
+the right signal for an eval leaderboard, but a terrible gradient for
+RL training — an agent that fixes 4 of 5 failing tests scores the same
+0.0 as one that fixes nothing.
+
+So this verifier emits BOTH:
+  * /logs/verifier/reward.txt  — the GRADED scalar (training signal,
+        which Harbor reads):  reward = f2p_rate * p2p_factor
+  * /logs/verifier/reward-details.json — carries the strict SWE-bench
+        ``resolved`` bool (eval signal) PLUS the full breakdown.
+
+Refs: SWE-bench (F2P/P2P semantics), SWE-RL / SWE-Gym (dense reward for
+RL), UTBoost (weak-test coverage lets wrong patches pass — hence we
+record p2p_count so consumers can judge regression-guard strength).
+
+Scoring
+-------
+Given the baked FAIL_TO_PASS / PASS_TO_PASS test-name lists (computed by
+the generation-time two-stage validation) and the agent-run test log:
+
+  f2p_rate   = (# F2P tests now PASSED) / (# F2P tests)
+  p2p_rate   = (# P2P tests still PASSED) / (# P2P tests)   [1.0 if no P2P]
+  p2p_factor = p2p_rate          # regressions scale the reward down
+  reward     = f2p_rate * p2p_factor
+  resolved   = (all F2P pass) AND (all P2P pass)            # strict SWE-bench
+
+Oracle invariant: the gold patch flips every F2P and keeps every P2P,
+so f2p_rate=1.0, p2p_rate=1.0 -> reward=1.0 and resolved=True. This is
+what the T3 oracle gate (reward == 1.0) relies on.
+
+Graceful degradation: if the log can't be parsed into per-test
+statuses (unrecognized runner output), fall back to the exit-code
+reward (1.0 if the suite exited 0, else 0.0) and stamp
+``parse_status="fallback_exitcode"`` — never crash, never silently
+zero out a real fix.
+
+Pure stdlib — uses only ``argparse``, ``json``, ``os``, ``re``, ``sys``.
+The 4 per-runner parsers are condensed ports of
+``repo2rlenv.log_parsers.*`` kept in lockstep via the unit tests under
+``tests/test_pr_runtime_verifier.py``.

+# Issue
+
+**Title:** NPS scheme/fund-manager information is incorrectly split across page breaks
+
+## Description
+When generating documents that include NPS scheme and fund-manager details, the information is sometimes split incorrectly if a page break occurs within or between these sections. This results in incomplete or misaligned data on subsequent pages. The expected behavior is for the system to robustly handle page breaks, ensuring that NPS scheme and fund-manager information remains correctly grouped and displayed, even when spanning multiple pages.
+
+## Task
+
+Modify the repository so that the issue described above is resolved. The task's test suite verifies your patch by applying it on top of the base commit `31b743b0e8ba` and running the modified tests.
