The maintainer's correction: counts over a function, language or framework carry nothing about safety; the
object a decision model may see is the path from an attacker-reachable entry to a protected operation, with the
checks on it in control-flow order and the provenance of the operation's arguments. Requirement 9, the trace
contract and tasks 4.2 and 4.3.

Codex delivery under spec access-control-prover plus one fix of mine. Operation rows may now name a handler by
name pattern and framework (Jenkins form validation and list filling, Tornado request methods, Remix actions);
the mapper recognises Symfony, Livewire and Laravel controllers, Remix exports and Tornado handlers;
`obligations/enforcement.py` turns Laravel route middleware, Symfony attributes and security.yaml rules and
Tornado's authenticated decorator into router and decorator witnesses. The path walk looks each node's callers
up once per change and does not walk a tree with no recognised entry: one seatunnel change fell from 670 s to
35 s. One name Codex could not source (Tornado get_current_user) is left out and said so in the facts header.
Smoke on the 23 fix changes: 15 pushes caught (65 percent, Wilson 45 to 81), 55 of 93 locations, precision
15 of 15 flagged, no instrument failure, no change over 120 s. Delivery A caught 7.

Codex delivery under spec access-control-prover. `semantic/obligations/paths.py` builds entry-to-function path
records from the cached caller index; `mapping.py` names Stapler web methods and Jetty handlers as entries;
`check_obligations` gains the opt-in premise `assume_entries_protected` with the label `unguarded_path`;
`hunt/prover.py` proves a change with no model call and states its coverage; `benchmarks/valid/prover_arm.py`
scores it with the valid-benchmark metrics. Two fixes after the first smoke run: a product file git holds empty
is read, not unread (four changes failed on `__init__.py` and empty assets), and absent-input reasons are
counted by name.
Smoke on the 23 fix changes of the training pool: 7 pushes caught (30 percent, Wilson 16 to 51), 28 of 93
locations, precision 7 of 8 flagged, no instrument failure; three changes over the 120 second bound. Twelve of
the 17 Jenkins fixes reach the fixed method but check no operation because the method is the operation;
the spec now carries handler-named operations for delivery B.

Codex stopped on a real conflict: with path records and no clause or sibling norm the checker returns no finding
by design. The prover's premise (a recognised entry is protected unless declared public) is now an opt-in keyword
with its own label and evidence, default off, existing behaviour and tests unchanged.

A deterministic check that a protected operation is reachable from an entry point without a check dominating
the path, per framework, built on the existing obligations checker, caller index and entry mapper; scored as a
rule arm on the access-control training pool. Follows the maintainer's finding that the hunter's features
describe shape and cannot decide unsafety.
