Add precision guards for systematic agent false-positive patterns (#112)
* Add precision guards for systematic agent false-positive patterns

Encodes reviewer-confirmed FP guards from the online eval: tooltip-inherited, page-trigger default return, drill-down filter not visible in diff, dual-trigger CalcFields (do.md); and a released-baseline precondition for breaking-change/upgrade findings on never-shipped symbols.

* Scope suggested-code and location to exactly the changed lines

Addresses reviewer-reported misplaced suggestions from the eval: insert-only-property emitting the whole field, single-statement rewrites anchored on the procedure name, and reductive multi-line collapses. The skill now emits a location range that matches precisely the rewritten lines.

* Correct suggested-code scoping guidance to match one-click anchor mechanics

A lone inserted line matches no existing file line and cannot be anchored; bracket the new line with one adjacent unchanged line instead. Reductive collapses omit suggested-code and fall back to a manual snippet.

* Move BC-specific FP guards out of do.md into leaf skills

do.md is the stable action-skill template and must stay domain-agnostic (JesperSchulz review). Relocate the four known false-positive patterns to their domain leaves: ToolTip-inheritance to al-ui-review; drill-down/lookup filtering and CalcFields lifecycle to al-performance-review; page-trigger exit(true) semantics to al-error-handling-review.

* Move suggested-code line-scoping guidance out of do.md into al-code-review

do.md must not carry instructions for how the review skill behaves (JesperSchulz review). Relocate the location/suggested-code precise-span rules to al-code-review's existing Suggested-code guidance section. do.md is now unchanged vs main.

* Move false-positive guards from skills into knowledge files

Keep review skills slim (finders/appliers). The FP guards and released-baseline preconditions previously embedded in leaf skills become negative-clarification knowledge articles in their domains, and the agent-findings policy edits to al-ui/al-privacy are reverted to main. Adds 6 knowledge files: error-handling (page-boolean-triggers-default-to-true), ui (bound-page-field-inherits-source-field-tooltip), performance (calcfields-in-both-getrecord-triggers-is-not-redundant, page-effective-filter-may-live-outside-the-diff), breaking-changes (unreleased-symbol-change-is-not-a-breaking-change), upgrade (unreleased-schema-change-needs-no-upgrade-path).

* Revert branch's suggested-code scoping addition in al-code-review

The three location-span shapes added to al-code-review are output-format mechanics, not domain knowledge: one-click span correctness is the engine's job (Resolve-SuggestionPlacement) and do.md already owns the suggested-code/location contract. The AL concerns the examples illustrate are already covered by existing knowledge (use-isempty-for-existence-check, data-classification-required-on-pii-fields, no-space-before-method-parenthesis). Restores al-code-review to main; the branch now adds only the 6 knowledge files.

* Restore al-ui/al-privacy review skills to base (zero diff in PR)

These two leaf skills carried an accidental net change against the PR merge-base because an earlier revert used the current origin/main (post-#110) instead of the branch base (pre-#110). Restoring them to the merge-base version removes them from the PR diff entirely. Three-way merge still preserves main's #110 suppression.

A page field bound to a table field inherits that field's ToolTip

Description

A page field bound to a table field inherits the source field's ToolTip at runtime: the control shows the table field's ToolTip even when the page control declares none of its own. A page field without an inline ToolTip is therefore not, by itself, a missing-tooltip defect — the text may be supplied by the bound source field.

The genuinely-missing case — a bound field whose source table field also carries no ToolTip, or an unbound control that needs one — is already reported by the compiler analyzer AA0218, which BCQuality calibrates to info. That analyzer, not an agent finding, owns the missing-tooltip signal.

Best Practice

Do not raise a missing-ToolTip finding for a page field that has a source-table binding; assume the source field supplies the tooltip. Reserve tooltip findings for the cases the dedicated tooltip rules define, and let analyzer AA0218 carry the mechanically-detectable missing-tooltip case at its calibrated severity.

Anti Pattern

Flagging every page field that has no inline ToolTip property as an accessibility violation, ignoring that a bound field inherits its source field's tooltip and that AA0218 already covers the truly-missing case.
