- Around line 807-810: In ReadBlockFromDisk (the branch that currently does
`return error("ReadBlockFromDisk(CBlock&, CBlockIndex*): GetHash() doesn't match
index for %s at %s", pindex->ToString(), block_pos.ToString()); return false;`)
remove the unreachable `return false;` and instead replace the `return
error(...)` call with a logging call (e.g., LogError or the project's LogPrint
equivalent) that emits the same message using pindex->ToString() and
block_pos.ToString(), then follow it with `return false;` so the branch matches
the LogError(...); return false; pattern used elsewhere.

In `@src/validation.cpp`:
- Around line 2484-2488: The LogError call after Consensus::CheckTxInputs is
logging state.ToString() which is incorrect because the CheckTxInputs failure
details are in tx_state; update the LogError invocation in the ConnectBlock
error branch to include tx_state.ToString() (and/or
tx_state.GetRejectReason()/GetDebugMessage() if you prefer more detail) so the
actual transaction rejection reason from CheckTxInputs is recorded before
returning state.Invalid; keep the existing return that uses tx_state for the
reject reason/debug message.

In `@test/lint/lint-spelling.py`:
- Line 18: The list comprehension uses the loop variable named dir which shadows
the built-in dir() and triggers Ruff A001; update the variable name in the
expression that builds FILES_ARGS (the comprehension referencing
SHARED_EXCLUDED_SUBTREES) to a non-built-in name like subtree or subdir so it no
longer shadows the built-in (e.g., replace occurrences of dir inside the
comprehension with subtree).

- Around line 20-26: The EXCLUDED_DIRS list duplicates paths that are already
present in SHARED_EXCLUDED_SUBTREES; update the definition of EXCLUDED_DIRS to
avoid redundant entries by removing the hardcoded directory strings and simply
compose EXCLUDED_DIRS from any unique local exclusions (if any) plus
SHARED_EXCLUDED_SUBTREES, ensuring EXCLUDED_DIRS references
SHARED_EXCLUDED_SUBTREES (symbol names: EXCLUDED_DIRS, SHARED_EXCLUDED_SUBTREES)
so there is a single source of truth for shared exclusions.

- [BLOCKING] lines 806-810: Missed bitcoin#29236 conversion: stale `return error(...)` with unreachable `return false;`
  This site was not adapted during the bitcoin#29236 backport. `error(...)` already returns `false`, so the trailing `return false;` is unreachable and can trip `-Wunreachable-code` on warning-as-error builds. It is also the only call site in this PR's diff that still uses the old `error()` helper instead of the new `LogError(...) + return false` pattern, making the merge resolution inconsistent. Functionality is preserved (the function still returns false on hash mismatch), but the inconsistency should be fixed before merge.

In `src/validation.cpp`:
- [SUGGESTION] line 4781: LogError missing trailing `\n` in RollforwardBlock
  `LogError` expands to `LogPrintLevel_` and writes the formatted string verbatim via `LogPrintStr`. The logger uses the trailing `\n` to set `m_started_new_line` (logging.cpp:481), which controls whether the next entry receives its timestamp/source-location/threadname prefix. Without the terminator, the next log line is concatenated onto this one and loses its prefix. Every other LogError introduced by this PR (lines 4690, 4755, 4789, 4860, 4865, 4872, 4879, 4897, 4909, 4916) ends in `\n`; this one was missed during the conversion.
- [SUGGESTION] line 4924: LogError missing trailing `\n` on Dash-specific EvoDB inconsistency log
  Same root cause as line 4781: this Dash-specific call (note the `(DASH):` tag) was converted from `error(...)` but lost its newline. The next log entry will be glued onto this one without its usual prefix.
- [SUGGESTION] line 4936: LogError missing trailing `\n` in ReplayBlocks ReadBlockFromDisk failure
  Same missing-newline regression as 4781/4924. Format string ends with `...ToString())` with no `\n`, so the next log line loses its prefix.
- [SUGGESTION] line 4942: LogError missing trailing `\n` in ReplayBlocks DisconnectBlock failure
  Same missing-newline regression. Without the terminator, subsequent log records are concatenated and lose their normal metadata prefixing — particularly unhelpful when diagnosing replay/recovery failures.
- [SUGGESTION] line 5126: LogError missing trailing `\n` in LoadGenesisBlock catch handler
  Same missing-newline regression in the LoadGenesisBlock exception handler. Startup-time failures here are exactly the cases where preserving the prefix on the next log line matters for diagnosis.

- Around line 1-5: The list assignment for SHARED_EXCLUDED_SUBTREES has
misaligned continuation lines causing Flake8 E128/E124; fix it by consistently
aligning the items and the closing bracket (either put all items on the same
line or place each string on its own line indented to the same column under the
opening bracket), e.g. align each entry under the first list element and ensure
the closing ] lines up with the start of the assignment so
SHARED_EXCLUDED_SUBTREES is properly formatted.

In `@test/lint/lint-includes.py`:
- Around line 20-26: EXCLUDED_DIRS currently hardcodes directories that are also
present in SHARED_EXCLUDED_SUBTREES causing duplicates; update the EXCLUDED_DIRS
definition to avoid repeating entries by either removing the overlapping
hardcoded entries (leave only the unique ones plus SHARED_EXCLUDED_SUBTREES) or
build EXCLUDED_DIRS by concatenating and then deduplicating while preserving
order (e.g., use an ordered set/dedup logic) so that EXCLUDED_DIRS and
SHARED_EXCLUDED_SUBTREES do not contain duplicated paths; target the
EXCLUDED_DIRS symbol in the diff to implement the change.

In `src/validation.cpp`:
- [SUGGESTION] line 4781: `RollforwardBlock` leaves the log line unterminated after the `LogError` conversion
  `LogError` does not append a newline on its own. In `Logger::LogPrintStr`, `m_started_new_line` is only reset when the format string ends with `\n`, so this message leaves the logger in the middle of a line and the next record is emitted without its normal timestamp/category prefix. That makes block-replay failures materially harder to diagnose.
- [SUGGESTION] lines 4924-4942: `ReplayBlocks` has three unterminated `LogError` messages
  All three `LogError` calls added in this `ReplayBlocks` path omit a trailing newline. Because the logger prefixes only the start of a new line, any later log entry after one of these failures will be concatenated onto the same physical line and lose its normal metadata prefix. This affects EvoDB inconsistency reporting, rollback disk-read failures, and disconnect failures.
- [SUGGESTION] line 5126: `LoadGenesisBlock` logs startup failure without terminating the record
  The `catch` block was converted from `error(...)` to `LogError(...)`, but the newline was dropped. If genesis-block initialization throws, the next log record is appended to the same line and loses its usual prefix, which degrades exactly the startup diagnostics this path is supposed to preserve.
