Multi-argument parameterized layers silently mis-handled every
wrong-arity call:
- Missing args: cl-progv (since its Emacs 27 rewrite) binds
parameters beyond the supplied values to nil, never leaving them
unbound, so (tp-set "s" '(two-arg-layer "red")) quietly produced
(:foreground "red" :background nil) - while the docstring of
tp-layer-props-with-args falsely promised an unbound-variable
error.
- Excess flat-form args fell into extra-props and were applied as
garbage text-property KEYS with value nil ("green" as a property
name).
- The stack path (tp-push-layer with one arg for a two-parameter
layer) fell through tp--normalize-layer-spec's named-inline branch,
building an odd-length plist and dying with the cryptic "Odd length
text property list".
Fixes, per site:
- tp-layer-props-with-args checks (length args) against the arglist
and signals "tp layer NAME takes N argument(s), got M"; its
docstring now documents the explicit error instead of the
impossible unbound-parameter story. Extra values remain ignored
in this direct call, per the documented contract.
- tp--resolve-props signals the same error after the arity split when
fewer values were available (covering parameterized groups too),
and rejects flat-form excess positional args whose first extra
element is not a symbol (i.e. can never be a property key).
- tp--normalize-layer-spec signals "tp layer NAME expects N args,
got M" for any parameterized-layer arity mismatch instead of
falling through to the named-inline branch.
Correct-arity flat, wrapped, extra-props and group behavior is
unchanged (covered by controls in the new tests, which port the
review's verify-arg1 probe).

Reactive performance (tp-reactive/tp-render/tp-ops): layer->buffer
registry replaces full buffer-list scans on reactive updates, with a
conservative unknown->learning-scan fallback, kill-buffer pruning,
and tp-reactive-track-buffer to close the propertized-string-insert
gap; minimal-diff tp-text replacement preserves point and markers and
makes identical-text updates true no-ops; tp-gc-anonymous-layers
collects interned anonymous layers no registered buffer still shows.
Stack capabilities (tp-stack): tp-hide-layer/tp-show-layer visibility
(hidden layers stay in the stack but do not render; hiding the top
reveals the next visible layer), tp-lower-layer, tp-rotate-layer
DIRECTION/COUNT, tp-layer-stack-at, and modified-run-count returns
with NOERROR options.
Search and layer APIs (tp-search/tp-layer): SUBEXP capture groups and
START/END bounds for tp-regexp-*/tp-match-*, PREDICATE/NOT-CURRENT
exposure on tp-forward/tp-backward/-do (defaults keep 0.2.0 semantics),
multi-argument parameterized layers (define-tp/define-tps arglists of
any arity, tp-layer-props-with-args, tp-layer-arglist), and the
interactive tp-describe-layer.
79 new regression tests; combined suite 522/522 green, shuffled run
green, doctests 63/63, byte-compile clean with warnings-as-errors.

35 fixes across tp-layer.el, tp-stack.el, tp-search.el, tp-reactive.el
and tp-render.el, each empirically reproduced before and after:
layer-definition resolution/cycles/copying/cleanup, clipped region-local
stack mutators, symmetric backward search matching, length-changing
replacements, and reactive re-render correctness (replace-not-accumulate,
buffer-local isolation, batching union, per-interval props).
Adds four per-module regression suites (100 new tests); combined suite
is 438/438 green. tp-test-backward updated to the now-symmetric backward
matching contract it previously codified inverted. The string-vs-buffer
shortfall divergence in tp-forward-do/tp-backward-do is documented in
CHANGELOG as a known divergence rather than changed. Adds CHANGELOG.md.
