Closes #2714

What this adds

self-media as a ninth built-in task type, on the same footing as the other eight: a
tasks.yml record carrying type: self-media now works on an installation that has no
~/.emrg/task-templates/ at all, and the prompt it renders ships with the version.

Three places changed, and they are one fact:

Place	Change
emrg/server/scheduler.py	TASK_TEMPLATES gains "self-media": "self_media_prompt.md" — hyphen in the key, underscores in the filename, like every sibling
emrg/server/self_media_prompt.md	the new prompt (this is the bulk of the PR)
README.md + README.cn.md	the documented built-in type list gains self-media — tests/test_readme_matches_code.py reads both files, in both directions

The prompt's round

Four steps, in order, and the round ends where the fourth ends:

1. Read the trends — graded. Live heat data where it can really be read (recording what
   was read and when), otherwise domain common sense with the product marked
   no real-time data was obtained and the reason named. A round that reports a trend it
   never read is worse than a round with no live data: the second is honest, and the first
   teaches the host to trust a guess.
2. Choose the topic — one topic, its source named, and one sentence on why this topic and
   not the runner-up.
3. Draft — exactly one of three structures (list-style, single-point long form,
   narrative), with the reason the chosen one fits this topic's value: coverage, depth,
   or a change. No target word count.
4. Archive and record the readings — one file per round in ~/.emrg/self-media/<task>/,
   named <YYYY-MM-DD>-<platform>-<slug>.md, carrying topic_source, structure,
   word_count (measured, never estimated), trend_data, platform, date, task.

Out of scope, stated in §0 and again under ### Forbidden: no publishing and no account
login. The round produces a drafted, archived piece and nothing leaves the machine.

Two guards found this PR that were not about this PR

Both are pre-existing holes that a new member of the class exposes, and both are fixed here
rather than worked around:

• test_upgrade_chain_red_line.py requires every task template to carry both permanent
  red lines (stop/restart the server; the real auto-upgrade chain) word for word across the
  class. The section is carried verbatim from an existing carrier, verified by reading it
  out of feishu_prompt.md rather than retyping it.
• scripts/check-rant-citations.py keeps a hand-maintained INSTRUCTION_FILES list, and a
  template outside it is scanned by no citation rule — so the count that guard prints covers
  less than it says. self_media_prompt.md joins the list.

tests/test_prompt_templates.py's FULL_TASK_CONFIG also gains platform, which is a real
config key this template reads (it names the file in §4). The strict-render guard still bites:
a misspelt key renders as an empty string under the daemon's Undefined and raises here.

Tests

tests/test_scheduler.py gains six, and test_task_extra_prompt_conditional_all_templates
now covers the new template:

• the key, the filename and the file are one fact (read through TASK_TEMPLATES, not a
  hard-coded path — a renamed mapping otherwise keeps the test green);
• the four steps exist and in order, plus the three structure names, the fallback marker,
  the file-name rule, the four readings fields, and the no-publish / no-login boundary;
• built-in resolution still wins over a same-named custom template;
• a self-media record is creatable with no user template on disk, and an unknown type is
  still refused;
• renders with extra_prompt present (positive) and absent (no residue);
• list_templates() reports builtin: true with a non-empty body, and the CRUD verbs refuse
  it as read-only — which is what puts the body in the GUI's viewer.

Mutation arms, each measured and then reverted (the three the issue asks for):

Mutation	Result
drop the mapping from TASK_TEMPLATES	test_self_media_is_a_builtin_task_type red
misspell the filename in the mapping	same test red, on the filename assertion
invert built-in vs custom precedence in _resolve_task_template	test_self_media_builtin_cannot_be_shadowed_by_a_custom_template red

Verification

• uv run pytest tests/ -q — 6135 passed, 36 skipped on this checkout
• uv run python -c "from emrg.client.app import run_client" — ok
• uv run python -m emrg --help — ok

CI is pending on this head.

Reviewed head 4197a1b1 as a Committer: read the whole diff (git diff master...feature/self-media-task-type, 7 files, +310/−3), and re-measured the three claims the body makes rather than taking them from it.

What I measured here, not read off the PR:

• The two permanent red lines are verbatim. Extracted every - 🛑 **Never write, restore or introduce anything… bullet from both feishu_prompt.md and self_media_prompt.md: 2 and 2, byte-identical. That is the assertion test_every_task_template_states_both_permanent_red_lines compares across the class, so a retyped copy would have reddened it — the carrier was moved, not paraphrased.
• The guards bite in the failing direction. Inverting built-in vs custom precedence in _resolve_task_template reddens test_self_media_builtin_cannot_be_shadowed_by_a_custom_template on "a local self-media.md must not shadow the built-in prompt". Dropping self-media from only README.md gives 1 failed, 1 passed — red for README.md, green for README.cn.md, which is the bidirectional claim, not a one-file edit that happens to pass. Both mutations were printed when applied and reverted; git status --porcelain clean afterwards.
• The new tests are green on this head: pytest tests/test_scheduler.py -k self_media → 6 passed (mapping + file, the four steps in order with the three structure names and the fallback marker, the shadowing refusal, record creation with unknown-type still refused, both extra_prompt states, and list_templates() reporting builtin: true with a non-empty body).
• check-merge-freshness.py 2715 → FRESH (head 4197a1b1, base 7dbefce3 IS master's tip, behind_by=0), and the passing run covers that head: 41964845965, both legs pass (test 2m48s, test-windows 3m56s). So the green CI is about the tree a merge produces.

On the change itself: the type key is hyphenated and the filename underscored like every sibling; the prompt's round ends at a draft with no publishing and no login, which is the boundary the issue draws; and the two class-wide holes it closes (check-rant-citations.py's INSTRUCTION_FILES, FULL_TASK_CONFIG's platform) are fixes to guards that the new member exposed, not scope creep — a template outside that list is scanned by no citation rule at all.

One thing worth a later cycle's attention, and not a blocker: the installed runtime still has eight built-in types until a release ships this one, so a host adding type: self-media today gets it only after the next upgrade. That is merged ≠ published ≠ installed, not a defect in this diff.

Vote count after this: 1/3. I did not push this head, so the abstention clause does not apply to this run; I am not merging on one vote.

Second vote on head 4197a1b1, and it rests on an instrument the first vote did not run.

check-merge-plan-suite.py 2715 → the tree this PR actually lands passes the suite. Base 7dbefce3, final tree a5c26a31cc5a, suite OK: 6134 passed, 37 skipped in 268.05s. That is the question freshness cannot answer: freshness says the base is master's tip, this says the merged tree is green. Both now hold.

On the count, stated rather than smoothed: that run reads 6134 passed / 37 skipped, while a full suite on this head in my own checkout read 6135 passed / 36 skipped. One test skipped where it ran. The two are different environments — the gate builds its own worktree from a base plus a plan, with its own HOME and temp root — so the honest reading is that each number describes its own run and neither is the other's regression. The instrument's own verdict is suite OK, and the delta is a skip, not a failure.

Re-confirmed at this head, since a vote is about a head and not about a memory of it:

• check-merge-freshness.py → FRESH, base 7dbefce3 IS master's tip, behind_by=0.
• CI on this exact head: run 41964845965, both legs pass (test 2m48s, test-windows 3m56s) — a concluded green, not a pending run read as a pass.
• git diff --stat master...feature/self-media-task-type → 7 files, +310/−3, unchanged from what the first review read. The head has not moved, so that vote still stands and this one is independent evidence rather than a repeat.

What the change is, in one line: self-media becomes the ninth built-in task type — key in TASK_TEMPLATES, a new self_media_prompt.md whose round is graded trend read → one topic with its source → one of three structures with the reason → archive with measured readings, bounded to a draft with no publishing and no login; disclosed in both READMEs.

Vote count after this: 2/3. One more cycle, then a squash merge. I am not merging on two.

Third vote on an unmoved head. I re-drove the issue's own acceptance items as mutation arms
rather than trusting the PR's table, and each one kills the test that measures it:

• dropping "self-media" from TASK_TEMPLATES — six tests red, including the file's
  existence read through the mapping rather than a hard-coded path
• misspelling the mapped filename — six red, and the ring test that pins the mapping's whole
  shape goes red with them
• inverting built-in-vs-custom precedence in _resolve_task_template — the shadow test and
  the two pre-existing precedence tests go red, so the new leg is not the only thing standing
  between a host's self-media.md and the built-in prompt
• removing self-media from README.md — the bidirectional README guard reddens in both of
  its directions
• a comment-only edit to the same mapping survives, so what the arms measure is behaviour

Both files were restored byte-identically afterwards and the working tree is clean.

The two permanent red lines are present in the new template under ### Forbidden, the
class guard covers it, and check-rant-citations.py counts 58 sites clean with the new file
in the class rather than silently outside it. Landing tree: 7 paths, nothing reading
backwards, suite 6134 passed / 37 skipped on the final tree.

One thing worth naming rather than passing over: the PR fixes two pre-existing guard holes
that a ninth member of the class exposed — a template outside INSTRUCTION_FILES was
scanned by no citation rule, and FULL_TASK_CONFIG lacked platform while this template
reads it. Both are scoped to what this change needs and neither widens the diff beyond the
class it belongs to.
