tp--buffer-has-layer-region-p tested liveness with a direct tp-name
property search, which only sees the rendered top layer of each run.
A layer buried below a pushed top, or hidden via tp-hide-layer, keeps
its tp-name inside the tp-layers storage property, so:
- tp-gc-anonymous-layers undefined layers a live buffer still held,
destroying their definitions and reactive deps; pop/show later
resurfaced text whose reactivity was permanently dead;
- tp-reactive-track-buffer (the documented remedy for the
string-insertion registration gap) never registered buried or
hidden layers either, so the gap-closer itself had the gap.
Fix:
- tp-reactive.el gains the shared stack-aware scan
tp-reactive--buffer-layer-names: a tp--map-intervals walk that
collects the direct tp-name of each run plus the tp-name of every
plist inside the run's tp-layers value (read as a plain list of
plists, so tp-reactive needs nothing from the stack module).
tp-reactive-track-buffer is rewritten on it.
- tp--buffer-has-layer-region-p is rewritten on the same scan and
moves - together with tp-gc-anonymous-layers (autoload kept) - from
tp-render.el into tp-layer.el beside tp--anonymous-layer-registry,
so the whole anonymous-layer lifecycle (mint, intern, undefine,
collect) lives in one module and tp-render sheds its only
non-rendering responsibility. tp-render's tp--map-layer-buffers
keeps calling the predicate downward.
Regression tests port the review's gc1/xm02 probes: buried-under-push
kept alive with reactivity surviving a later pop; hidden layer kept
alive with show+setq re-rendering; track-buffer registering buried
and all-hidden layers from inserted strings. Existing tests cover
the visible-kept and killed-buffer-collected control cases.

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.
