Many of the clues had a fresh feeling about them. There were a lot of clues with anagrams inside some other piece of wordplay – in one case, inside another anagram. But they all worked nicely for me. My clue of the day was 19dn, for its sheer elegance, with 25ac as an honourable mention.
Thanks to the setter for a very enjoyable puzzle.
Clues are in blue, with definitions underlined. Answers are in BOLD CAPS, then wordplay. (ABC*) means 'anagram of ABC', with the anagram indicator in bold italics. Deletions are in [square brackets].
Across
1 Publish charter again (7)
RELEASE: or RE-LEASE.
5 Triviality media bigwig messed up (7)
FLUFFED: FLUFF / ED.
9 Realisticrepresentation of death row cages not amended (4-2-5)
DOWN-TO-EARTH: nested anagrams! Something over-complicated about that, but the setter no doubt did it that way to make the surface smoother. It’s (NOT*) “caged by” (DEATH ROW*).
10 Bash meat loudly (3)
LAM: sounds like (“loudly”) LAMB.
11 Cabinet's primary material for drawer? (6)
CRAYON: C[abinet] / RAYON.
12 Lovely, neutral country preparing for war (8)
CHARMING: CH (the code for Switzerland) / ARMING.
14 Drill crushing walls bare when plastered (6-7)
SQUARE BASHING: (BARE*) “walled by” SQUASHING. Is this expression used in North America? I think it’s mainly a British usage.
17 Absolute farce bunglingset of measurements (8,5)
BEAUFORT SCALE: (ABSOLUTE FARCE*). Is a scale a “set” of measurements? I think it’s acceptable here, since the scale is a set of 18 values for measuring wind strength, running from 0 for dead calm to 17 for the worst level of hurricane.

NEONATAL: (ONE*) inside NATAL.
23 Outline prow of sailing vessel (6)
SKETCH: S[ailing] / KETCH.

AMBIVALENCE: LAV (“ladies”, perhaps) reversed and inserted into AMBIENCE.
27 Simple cattle pens sow destroyed (2,5)
NO SWEAT: (SOW*) inside NEAT (cattle). It took me a while and some helpers to give up looking for an anagram of (PENS SOW*).
28 Tease feeble individual, one undesirable in bed? (7)
RAGWEED: RAG / WEED. A garden bed, that is.
Down

13 British go on about stray animal in stories (4,6)
BRER RABBIT: B (British), then ERR (stray) in RABBIT (go on). The answer jumped out once I had the first R to help and assumed a B would go before.

SPARK PLUG: SP (special – it’s in Chambers for one) / ARK (old box, as in Raiders of the Lost ARK) / PLUG (trailer - that thing they show before the movie in the cinema).
